Fix use of uninitialized fields reported by valgrind
In pixman-noop.c and pixman-sse2.c, we are accessing
image->bits.width/height without first making sure the image is a bits
image. The warning is harmless because we never act on this
information without checking that the image is a8r8g8b8, but valgrind
does warn about it.
In pixman-noop.c, just reorder the clauses in the if statement; in
pixman-sse2.c require images to have the FAST_PATH_BITS_IMAGE flag
set.

be replaced with new template just by wrapping existing macros.

ARM: NEON: Bilinear macro template for instruction scheduling
This macro template takes 6 code blocks.
1. process_last_pixel
2. process_two_pixels
3. process_four_pixels
4. process_pixblock_head
5. process_pixblock_tail
6. process_pixblock_tail_head
process_last_pixel does not need to update horizontal weight. This
is done by the template. two and four code block should update
horizontal weight inside of them. head/tail/tail_head blocks
consist unrolled core loop. You can apply instruction scheduling
to the tail_head blocks.
You can also specify size of the pixel block. Supported size is 4
and 8. If you want to use mask, give BILINEAR_FLAG_USE_MASK flags
to the template, then you can use register MASK. When using d8~d15
registers, give BILINEAR_FLAG_USE_ALL_NEON_REGS to make sure
registers are properly saved on the stack and later restored.

them.

Use sentinels instead of special casing first and last stops
When storing the gradient stops internally, allocate two more stops,
one before the beginning of the stop list and one after the
end. Initialize those stops based on the repeat property of the
gradient.
This allows gradient_walker_reset() to be simplified because it can
now simply pick the two closest stops to the position without special
casing the first and last stops.

gradient walker: Correct types and fix formatting
The type of pos in gradient_walker_reset() and gradient_walker_pixel()
is pixman_fixed_48_16_t and not pixman_fixed_32_32. The types of the
positions in the walker struct are pixman_fixed_t and not int32_t, and
need_reset is a boolean, not an integer. The spread field should be
called repeat and have the type pixman_repeat_t.
Also fix some formatting issues, make gradient_walker_reset() static,
and delete the pointless PIXMAN_GRADIENT_WALKER_NEED_RESET() macro.

Simple repeat: Extend too short source scanlines into temporary buffer
Too short scanlines can cause repeat handling overhead and optimized
pixman composite functions usually process a bunch of pixels in a
single loop iteration it might be beneficial to pre-extend source
scanlines. The temporary buffers will usually reside in cache, so
accessing them should be quite efficient.

Make sure iwMMXt is only detected on ARM
iwMMXt is incorrectly detected on x86 and amd64. This happens because
the test uses standard _mm_* intrinsic functions which it compiles with
-march=iwmmxt, but when the user has set CFLAGS=-march=k8 for instance,
no error is generated from -march=iwmmxt, even though it's not a valid
flag on x86/amd64. Passing CFLAGS=-march=native does not override the
-march=iwmmxt flag though, which is why it wasn't noticed before.
So, just #error out in the test if the __arm__ preprocessor directive
isn't defined.

Check in configure for at least gcc-4.6, since gcc-4.7 (and hopefully

_mm_srli_si64 which is known to cause unpatched compilers to fail.
Select iwmmxt at runtime only after NEON, since we expect the NEON
optimizations to be more capable and faster than iwmmxt.

BILINEAR->NEAREST filter optimization for simple rotation and translation
Simple rotation and translation are the additional cases when BILINEAR
filter can be safely reduced to NEAREST.
commit ad5c6bbb36c1c5e72313f7c7bc7c6e6b7e79daba
Author: Søren Sandmann Pedersen <ssp@redhat.com>
Date: Sun Sep 4 02:53:39 2011 -0400
Strength-reduce BILINEAR filter to NEAREST filter for identity transforms
An image with a bilinear filter and an identity transform is
equivalent to one with a nearest filter, so there is no reason the
standard fast paths shouldn't be usable.
But because a BILINEAR filter samples a 2x2 pixel block in the source
image, FAST_PATH_SAMPLES_COVER_CLIP can't be set in the case where the
source area is the entire image, because some compositing operations
might then read pixels outside the image.
This patch fixes the problem by splitting the
FAST_PATH_SAMPLES_COVER_CLIP flag into two separate flags
FAST_PATH_SAMPLES_COVER_CLIP_NEAREST and
FAST_PATH_SAMPLES_COVER_CLIP_BILINEAR that indicate that the clip
covers the samples taking into account NEAREST/BILINEAR filters
respectively.
All the existing compositing operations that require
FAST_PATH_SAMPLES_COVER_CLIP then have their flags modified to pick
either COVER_CLIP_NEAREST or COVER_CLIP_BILINEAR depending on which
filter they depend on.
In compute_image_info() both COVER_CILP_NEAREST and
COVER_CLIP_BILINEAR can be set depending on how much room there is
around the clip rectangle.
Finally, images with an identity transform and a bilinear filter get
FAST_PATH_NEAREST_FILTER set as well as FAST_PATH_BILINEAR_FILTER.

test: better coverage for BILINEAR->NEAREST filter optimization
The upcoming optimization which is going to be able to replace BILINEAR filter
with NEAREST where appropriate needs to analyze the transformation matrix
and not to make any mistakes.
The changes to affine-test include:
1. Higher chance of using the same scale factor for x and y axes. This can help
to stress some special cases (for example the case when both x and y scale
factors are integer). The same applies to x/y translation.
2. Introduced a small chance for "corrupting" transformation matrix by flipping
random bits. This supposedly can help to identify the cases when some of the
fast paths or other code logic is wrongly activated due to insufficient checks.

Eliminate compute_sample_extents() function
In analyze_extents(), instead of calling compute_sample_extents() call
compute_transformed_extents() and inline the remaining part of
compute_sample_extents(). The upcoming bilinear->nearest optimization
will do something different with these two pieces of code.

Split computation of sample area into own function
compute_sample_extents() have two parts: one that computes the
transformed extents, and one that checks whether the computed extents
fit within the 16.16 coordinate space.
Split the first part into its own function
compute_transformed_extents().

Remove x and y coordinates from analyze_extents() and compute_sample_extents()
These coordinates were only ever used for subtracting from the extents
box to put it into the coordinate space of the image, so we might as
well do this coordinate translation only once before entering the
functions.

are now in a static library, which gets linked to all the tests and

bits: optimise fetching width==1 repeats
Profiling ign.com, 20% of the entire render time was absorbed in this
single operation:
<< /content //COLOR_ALPHA /width 480 /height 800 >> surface context
<< /width 1 /height 677 /format //ARGB32 /source <|!!!@jGb!m5gD']#$jFHGWtZcK&2i)Up=!TuR9`G<8;ZQp[FQk;emL9ibhbEL&NTh-j63LhHo$E=mSG,0p71`cRJHcget4%<S\X+~> >> image pattern
//EXTEND_REPEAT set-extend
set-source
n 0 0 480 677 rectangle
fill+
pop
which is a simple composition of a single pixel wide image. Sadly this
is a workaround for lack of independent repeat-x/y handling in cairo and
pixman. Worse still is that the worst-case behaviour of the general repeat
path is for width 1 images...

Workaround bug in llvm-gcc
llvm-gcc (shipped in Apple XCode 4.1.1 as the default compiler or in
the 2.9 release of LLVM) performs an invalid optimization which
unifies the empty_region and the bad_region structures because they
have the same content.
A bugreport has been filed against Apple Developers Tool for this
issue. This commit works around this bug by making one of the two
structures volatile, so that it cannot be merged.

In pixman_image_create_bits() allow images larger than 2GB
There is no reason for pixman_image_create_bits() to check that the
image size fits in int32_t. The correct check is against size_t since
that is what the argument to calloc() is.
This patch fixes this by adding a new _pixman_multiply_overflows_size()
and using it in create_bits(). Also prepend an underscore to the names
of other similar functions since they are internal to pixman.
V2: Use int, not ssize_t for the arguments in create_bits() since
width/height are still limited to 32 bits, as pointed out by Chris
Wilson.

Speed up pixman_region{,32}_contains_rectangle()
When someone selects some text in Firefox under a non-composited X
server and initiates a drag, a shaped window is created with a complex
shape corresponding to the outline of the text. Then, on every mouse
movement pixman_region_contains_rectangle() is called many times on
that complicated region. And pixman_region_contains_rectangle() is
doing a linear scan through the rectangles in the region, although the
scan does exit when it finds the first box that can't possibly
intersect the passed-in rectangle.
This patch changes the loop so that it uses a binary search to skip
boxes that don't overlap the current y position. The performance
improvement for the text dragging case is easily noticable.
V2: Use the binary search for the "getting up to speed or skippping
remainder of band" as well.

Fix lcg_rand_u32() to return 32 random bits.
The lcg_rand() function only returns 15 random bits, so lcg_rand_u32()
would always have 0 in bit 31 and bit 15. Fix that by calling
lcg_rand() three times, to generate 15, 15, and 2 random bits
respectively.
V2: Use the 10/11 most significant bits from the 3 lcg results and mix
them with the low ones from the adjacent one, as suggested by Andrea
Canciani.

C fast path for scaled src_x888_8888 with nearest filter
The necessity is justified by a message in the pixman mailing list:
http://lists.freedesktop.org/archives/pixman/2011-July/001330.html
NONE repeat is not supported, but could be added by tweaking
the interpretation and making use of 'fully_transparent_src'
scanline function argument.

Rename "det" as "discr" to make it match the mathematical name
"discriminant".

Bilinear REPEAT_NORMAL source line extension for too short src_width
To avoid function call and other calculation overhead, extend source
scanline into temporary buffer when source width is too small.
Temporary buffer will be repeatedly accessed, so extension cost is
very small due to cache effect.

REPEAT_NORMAL support for bilinear fast path template
The basic idea is to break down normal repeat into a set of
non-repeat scanline compositions and stitching them together.
Bilinear may interpolate last and first pixels of source scanline.
In this case, we can use temporary wrap around buffer.

Replace boolean arguments with flags for bilinear fast path template
By replacing boolean arguments with flags, the code can be more
readable and flags can be extended to do some more things later.
Currently following flags are defined.
FLAG_NONE
- No flags are turned on.
FLAG_HAVE_SOLID_MASK
- Template will generate solid mask composite functions.
FLAG_HAVE_NON_SOLID_MASK
- Template will generate bits mask composite functions.
FLAG_HAVE_SOLID_MASK and FLAG_NON_SOLID_MASK should be mutually
exclusive.

ARM: Fix two bugs in neon_composite_over_n_8888_0565_ca().
The first bug is that a vmull.u8 instruction would store its result in
the q1 register, clobbering the d2 register used later on. The second
is that a vraddhn instruction would overwrite d25, corrupting the q12
register used later.
Fixing the second bug caused a pipeline bubble where the d18 register
would be unavailable for a clock cycle. This is fixed by swapping the
instruction with its successor.

Move noop dest fetching to noop implementation
It will at some point become useful to have CPU specific destination
iterators. However, a problem with that, is that such iterators should
not be used if we can composite directly in the destination image.
By moving the noop destination iterator to the noop implementation, we
can ensure that it will be chosen before any CPU specific iterator.

Add a noop composite function for the DST operator
The DST operator doesn't actually do anything, so add a noop "fast
path" for it, instead of checking in pixman_image_composite32().
The performance tradeoff here is that we get rid of a test for DST in
the common case where the operator is not DST, in return for an extra
walk over the clip rectangles in the uncommon case where the operator
actually is DST.

Add a "noop" implementation.
This new implementation is ahead of all other implementations in the

ie., they don't require any work. For example, it might contain a
"fast path" for the DST operator that doesn't actually do anything or
an iterator for a8r8g8b8 that just returns a pointer into the image.

Offset rendering in pixman_composite_trapezoids() by (x_dst, y_dst)
Previously, this function would do coordinate calculations in such a
way that (x_dst, y_dst) would only affect the alignment of the source
image, but not of the traps, which would always be considered to be in
absolute destination coordinates. This is unlike the
pixman_image_composite() function which also registers the mask to the
destination.
This patch makes it so that traps are also offset by (x_dst, y_dst).
Also add a comment explaining how this function is supposed to
operate, and update tri-test.c and composite-trap-test.c to deal with
the new semantics.

Add support for the r8g8b8a8 and r8g8b8x8 formats to the tests.
commit f05a90e5f8d1d0af60e2c684cbe9f1327c33135a
Author: Alexandros Frantzis <alexandros.frantzis@linaro.org>
Date: Fri Mar 18 14:36:15 2011 +0200
Add simple support for the r8g8b8a8 and r8g8b8x8 formats.
This format is particularly useful on big-endian architectures, where RGBA in
memory/file order corresponds to r8g8b8a8 as an uint32_t. This is important
because RGBA is in some cases the only available choice (for example as a pixel
format in OpenGL ES 2.0).

test: Randomize some tests if PIXMAN_RANDOMIZE_TESTS is set
This patch makes so that composite and stress-test will start from a
random seed if the PIXMAN_RANDOMIZE_TESTS environment variable is
set. Running the test suite in this mode is useful to get more test
coverage.
Also, in stress-test.c make it so that setting the initial seed causes
threads to be turned off. This makes it much easier to see when
something fails.

Simplify the prototype for iterator initializers.
All of the information previously passed to the iterator initializers
is now available in the iterator itself, so there is no need to pass
it as arguments anymore.

Fill out parts of iters in _pixman_implementation_{src,dest}_iter_init()
This makes _pixman_implementation_{src,dest}_iter_init() responsible
for filling parts of the information in the iterators. Specifically,
the information passed as arguments is stored in the iterator.
Also add a height field to pixman_iter_t().

In delegate_{src,dest}_iter_init() call delegate directly.
There is no reason to go through
_pixman_implementation_{src,dest}_iter_init(), especially since
_pixman_implementation_src_iter_init() is doing various other checks
that only need to be done once.
Also call delegate->src_iter_init() directly in pixman-sse2.c

ARM: a bit faster NEON bilinear scaling for r5g6b5 source images
Instructions scheduling improved in the code responsible for fetching r5g6b5
pixels and converting them to the intermediate x8r8g8b8 color format used in
the interpolation part of code. Still a lot of NEON stalls are remaining,
which can be resolved later by the use of pipelining.

SSE2 optimization for bilinear scaled 'src_8888_8888'
A primitive naive implementation of bilinear scaling using SSE2 intrinsics,
which only handles one pixel at a time. It is approximately 2x faster than
pixman general compositing path. Single pass processing without intermediate
temporary buffer contributes to ~15% and loop unrolling contributes to ~20%
of this speedup.

Main loop template for fast single pass bilinear scaling
Can be used for implementing SIMD optimized fast path
functions which work with bilinear scaled source images.
Similar to the template for nearest scaling main loop, the
following types of mask are supported:
1. no mask
2. non-scaled a8 mask with SAMPLES_COVER_CLIP flag
3. solid mask
PAD repeat is fully supported. NONE repeat is partially
supported (right now only works if source image has alpha
channel or when alpha channel of the source image does not
have any effect on the compositing operation).

composite-test which shows off all the compositing operators).

Better support for NONE repeat in nearest scaling main loop template
Scaling function now gets an extra boolean argument, which is set
to TRUE when we are fetching padding pixels for NONE repeat. This
allows to make a decision whether to interpret alpha as 0xFF or 0x00
for such pixels when working with formats which don't have alpha
channel (for example x8r8g8b8 and r5g6b5).

C fast paths for a simple 90/270 degrees rotation
Depending on CPU architecture, performance is in the range of 1.5 to 4 times
slower than simple nonrotated copy (which would be an ideal case, perfectly
utilizing memory bandwidth), but still is more than 7 times faster if
compared to general path.
This implementation sets a performance baseline for rotation. The use
of SIMD instructions may further improve memory bandwidth utilization.

Move fallback decisions from implementations into pixman-cpu.c.
Instead of having each individual implementation decide which fallback
to use, move it into pixman-cpu.c, where a more global decision can be
made.
This is accomplished by adding a "fallback" argument to all the
pixman_implementation_create_*() implementations, and then in
_pixman_choose_implementation() pass in the desired fallback.

the _pixman_image_get_scanline_generic_64 can be moved to

_pixman_image_get_scanline_32/64, so these can be deleted.

Add iterators in the general implementation
We add a new structure called a pixman_iter_t that encapsulates the
information required to read scanlines from an image. It contains two
functions, get_scanline() and write_back(). The get_scanline()
function will generate pixels for the current scanline. For iterators
for source images, it will also advance to the next scanline. The
write_back() function is only called for destination images. Its
function is to write back the modified pixels to the image and then
advance to the next scanline.
When an iterator is initialized, it is passed this information:
- The image to iterate
- The rectangle to be iterated
- A buffer that the iterator may (but is not required to) use. This
buffer is guaranteed to have space for at least width pixels.
- A flag indicating whether a8r8g8b8 or a16r16g16b16 pixels should
be fetched
There are a number of (eventual) benefits to the iterators:
- The initialization of the iterator can be virtualized such that
implementations can plug in their own CPU specific get_scanline()
and write_back() functions.
- If an image is horizontal, it can simply plug in an appropriate
get_scanline(). This way we can get rid of the annoying
classify() virtual function.
- In general, iterators can remember what they did on the last
scanline, so for example a REPEAT_NONE image might reuse the same
data for all the empty scanlines generated by the zero-extension.
- More detailed information can be passed to iterator, allowing
more specialized fetchers to be used.
- We can fix the bug where destination filters and transformations
are not currently being ignored as they should be.
However, this initial implementation is not optimized at all. We lose
several existing optimizations:
- The ability to composite directly in the destination
- The ability to only fetch one scanline for horizontal images
- The ability to avoid fetching the src and mask for the CLEAR
operator
Later patches will re-introduce these optimizations.

A new configure option --enable-static-testprogs
This option can be used for building fully static binaries of the test
programs so that they can be easily run using qemu-user. With binfmt-misc
configured, 'make check' works fine for crosscompiled pixman builds.

Make 'fast_composite_scaled_nearest_*' less suspicious
Taking address of a variable and then using it as an array looks suspicious
to static code analyzers. So change it into an array with 1 element to make
them happy. Both old and new variants of this code are correct because 'vx'
and 'unit_x' arguments are set to 0 and it means that the called scanline
function can only access a single element of 'zero' buffer.

Bugfix for a corner case in 'pixman_transform_is_inverse'
When 'pixman_transform_multiply' fails, the result of multiplication just
could not have been identity matrix (one of the values in the resulting
matrix can't be represented as 16.16 fixed point value). So it is safe
to return FALSE.

Fix linking issues when HAVE_FEENABLEEXCEPT is set.
All objects using test/util.c fail to link:
| CCLD region-test
| /usr/bin/ld: utils.o: in function enable_fp_exceptions:utils.c(.text+0x939): error: undefined reference to 'feenableexcept'
There's indeed no explicit dependency on -lm, and if HAVE_FEENABLEEXCEPT
happens to be set, test/util.c uses feenableexcept(), which is nowhere
to be found while linking.
Fix this by adding -lm to TEST_LDADD, although two alternatives could be
thought of:
- Only specifying -lm for objects using util.c.
- Introducing a conditional to add -lm only when configure detects
have_feenableexcept=yes.

Fix for potential unaligned memory accesses
The temporary scanline buffer allocated on stack was declared
as uint8_t array. As a result, the compiler was free to select
any arbitrary alignment for it (even though there is typically
no reason to use really weird alignments here and the stack is
normally at least 4 bytes aligned on most platforms). Having
improper alignment is non-portable and can impact performance
or even make the code misbehave depending on the target platform.
Using uint64_t type for this array should ensure that any possible
memory accesses done by pixman code are going to be handled correctly
(pixman-combine64.c can access this buffer via uint64_t * pointer).
Some alignment related problem was reported in:

ARM: reuse common NEON code for over_{n_8|8888_n|8888_8}_0565
Renamed suppementary macros from 'over_n_8_0565' to 'over_8888_8_0565',
because they can actually support all variants of this operation:
over_8888_8_0565/over_n_8_0565/over_8888_n_0565.
Also 'over_8888_8_0565' now uses more optimized common code instead of its
own variant, improving performance a bit. Even though this operation is
still memory bandwidth limited, scaled variants of these fast paths may
put more stress on CPU later.

ARM: better NEON instructions scheduling for over_n_8_0565
Code rearranged to get better instructions scheduling for ARM Cortex-A8/A9.
Now it is ~30% faster for the pixel data in L1 cache and makes better use
of memory bandwidth when running at lower clock frequencies (ex. 500MHz).
Also register d24 (pixels from the mask image) is now not clobbered by
supplementary macros, which allows to reuse them for the other variants
of compositing operations later.

This macro hides the implementation details of pixels fetching
for the mask image just like 'fetch_src_pixblock' does for the

This patch does not introduce any functional changes and the
resulting code in the compiled object file is exactly the same.

Fix opacity check
Radial gradients are "conical", thus they can have some non-opaque
parts even if all of their stops are completely opaque.
To guarantee that a radial gradient is actually opaque, it needs to
also have one of the two circles containing the other one. In this
case when extrapolating, the whole plane is completely covered (as
explained in the comment in pixman-radial-gradient.c).

ARM: optimization for scaled src_0565_0565 with nearest filter
The performance improvement is only in the ballpark of 5% when
compared against C code built with a reasonably good compiler
(gcc 4.5.1). But gcc 4.4 produces approximately 30% slower code
here, so assembly optimization makes sense to avoid dependency
on the compiler quality and/or optimization options.

ARM: performance tuning of NEON nearest scaled pixel fetcher
Interleaving the use of NEON registers helps to avoid some stalls

ARM: macro template in C code to simplify using scaled fast paths
This template can be used to instantiate scaled fast path functions
by providing main loop code and calling NEON assembly optimized
scanline processing functions from it. Another macro can be used
to simplify adding entries to fast path tables.

ARM: nearest scaling support for NEON scanline compositing functions
Now it is possible to generate scanline processing functions
for the case when the source image is scaled with NEAREST filter.
Only 16bpp and 32bpp pixel formats are supported for now. But the
others can be also added later when needed. All the existing NEON
fast path functions should be quite easy to reuse for implementing
fast paths which can work with scaled source images.

ARM: NEON: source image pixel fetcher can be overrided now
Added a special macro 'pixld_src' which is now responsible for fetching
pixels from the source image. Right now it just passes all its arguments
directly to 'pixld' macro, but it can be used in the future to provide
a special pixel fetcher for implementing nearest scaling.
The 'pixld_src' has a lot of arguments which define its behavior. But
for each particular fast path implementation, we already know NEON
registers allocation and how many pixels are processed in a single block.
That's why a higher level macro 'fetch_src_pixblock' is also introduced
(it's easier to use because it has no arguments) and used everywhere
in 'pixman-arm-neon-asm.S' instead of VLD instructions.
This patch does not introduce any functional changes and the resulting code
in the compiled object file is exactly the same.

This was mostly harmless and had no effect on little endian systems.
But wrong vector element size is at least inconsistent and also
can theoretically cause problems on big endian ARM systems.

Do CPU features detection from 'constructor' function when compiled with gcc
There is attribute 'constructor' supported since gcc 2.7 which allows
to have a constructor function for library initialization. This eliminates
an extra branch for each composite operation and also helps to avoid
complains from race condition detection tools like helgrind.
The other compilers may or may not support this attribute properly.
Ideally, the compilers should fail to compile the code with unknown
attribute, so the configure check should do the right job. But in
reality the problems are surely possible. Fortunately such problems
should be quite easy to find because NULL pointer dereference should
happen almost immediately if the constructor fails to run.
clang 2.7:
supports __attribute__((constructor)) properly and pretends to be gcc
tcc 0.9.25:
ignores __attribute__((constructor)), but does not pretend to be gcc

[mmx] Mark some of the output variables as early-clobber.
GCC assumes that input variables in inline assembly are fully consumed
before any output variable is written. This means it may allocate the
variables in the same register unless the output variables are marked
as early-clobber.
From Jeremy Huddleston:
I noticed a problem building pixman with clang and reported it to
the clang developers. They responded back with a comment about
the inline asm in pixman-mmx.c and suggested a fix:
"""
Incidentally, Jeremy, in the asm that reads
__asm__ (
"movq %7, %0\n"
"movq %7, %1\n"
"movq %7, %2\n"
"movq %7, %3\n"
"movq %7, %4\n"
"movq %7, %5\n"
"movq %7, %6\n"
: "=y" (v1), "=y" (v2), "=y" (v3),
"=y" (v4), "=y" (v5), "=y" (v6), "=y" (v7)
: "y" (vfill));
all the output operands except the last one should be marked as
earlyclobber ("=&y"). This is working by accident with gcc.

Remove workaround for a bug in the 1.6 X server.
There used to be a bug in the X server where it would rely on
out-of-bounds accesses when it was asked to composite with a
window as the source. It would create a pixman image pointing
to some bogus position in memory, but then set a clip region
to the position where the actual bits were.
Due to a bug in old versions of pixman, where it would not clip
against the image bounds when a clip region was set, this would
actually work. So when the pixman bug was fixed, a workaround was
added to allow certain out-of-bound accesses.
However, the 1.6 X server is so old now that we can remove this
workaround. This does mean that if you update pixman to 0.22 or later,
you will need to use a 1.7 X server or later.

Draw radial gradients with PDF semantics
Change radial gradient computations and definition to reflect the
radial gradients in PDF specifications (see section 8.7.4.5.4,
Type 3 (Radial) Shadings of the PDF Reference Manual).
Instead of having a valid interpolation parameter value for every
point of the plane, define it only for points withing the area
covered by the family of circles generated by interpolating or
extrapolating the start and end circles.
Points outside this area are now transparent black (rgba 0 0 0 0).
Points within this area have the color assiciated with the maximum
value of the interpolation parameter in that point (if multiple
solutions exist within the range specified by the extend mode).

Remove broken optimizations in combine_disjoint_over_u()
The first broken optimization is that it checks "a != 0x00" where it
should check "s != 0x00". The other is that it skips the computation
when alpha is 0xff. That is wrong because in the formula:
min (1, (1 - Aa)/Ab)
the render specification states that if Ab is 0, the quotient is
defined to positive infinity. That is the case even if (1 - Aa) is 0.

Delete simple repeat code
This was supposedly an optimization, but it has pathological cases
where it definitely isn't. For example a 1 x n image will cause it to
have terrible memory access patterns and to generate a ton of modulus
operations.
Since no one has ever measured whether it actually is an improvement,
and since it is doing the repeating at the wrong the stage in the
pipeline, and since with the previous commit it can't be triggered
anymore because we now require SAMPLES_COVER_CLIP for regular fast
paths, just delete it.

Fix bug in FAST_PATH_STD_FAST_PATH
The standard fast paths deal with two kinds of images: solids and
bits. These two image types require different flags, but
PIXMAN_STD_FAST_PATH uses the same ones for both.
This patch makes it so that solid images just get the standard flags,
while bits images must be untransformed contain the destination clip
within the sample grid.
This means that the old FAST_PATH_COVERS_CLIP flag is now not used
anymore, so it can be deleted.

Some clean-ups in fence_malloc() and fence_free()
This patch removes an unnecessary typecast of MAP_FAILED,
replaces an erroneous free() by the correct munmap() in the
error path for a failing mprotect(), and, finally, removes
redundant calls to mprotect() that aren't necessary, because
munmap() doesn't call for any specific memory protection.

This test is a modified version of Siarhei's compositor throughput

consumption for the M-test, and with an additional 8x8-random test
intended to determine peak ops/sec capability. There are also quite a
lot more operations tested for.

Use a macro to generate some {a,x}8r8g8b8, a8, and r5g6b5 bilinear fetchers.
There are versions for all combinations of x8r8g8b8/a8r8g8b8 and
pad/repeat/none/normal repeat modes. The bulk of each scaler is an
inline function that takes a format and a repeat mode as parameters.
The new scalers are all commented out, but the next commits will
enable them one at a time to facilitate bisecting.

analyze_extents: Fast path for non-transformed BITS images
Profiling various cairo traces showed that we were spending a lot of
time in analyze_extents and compute_sample_extents(). This was
especially bad for glyphs where all this computation was completely
unnecessary.
This patch adds a fast path for the case of non-transformed BITS
images. The result is approximately a 6% improvement on the
firefox-talos-gfx benchmark:
Before:
[ # ] backend test min(s) median(s) stddev. count
[ 0] image firefox-talos-gfx 13.797 13.848 0.20% 6/6
After:
[ # ] backend test min(s) median(s) stddev. count
[ 0] image firefox-talos-gfx 12.946 13.018 0.39% 6/6

Move some of the FAST_PATH_COVERS_CLIP computation to pixman-image.c
When an image is solid or repeating, the FAST_PATH_COVERS_CLIP flag
can be set in compute_image_info().
Also the code that turned this flag off in pixman.c was not correct;
it didn't take transformations into account. With this patch, pixman.c
doesn't set the flag by default, but instead relies on the call to
compute_samples_extents() to set it when possible.

make check reports no problems. (Earlier I had to use --disable-mmx

Remove FAST_PATH_NARROW_FORMAT flag if there is a wide alpha map
If an image has an alpha map that has wide components, then we need to
use 64 bit processing for that image. We detect this situation in
pixman-image.c and remove the FAST_PATH_NARROW_FORMAT flag.
In pixman-general, the wide/narrow decision is now based on the flags
instead of on the formats.

variable in pixman-general.c to "narrow" and fixing up the logic
correspondingly, the code there reads a lot more straightforwardly.

SSE2 optimization for scaled over_8888_8888 operation with nearest filter
This is the first demo implementation, it should be possible to
generalize it later to cover more operations with less lines of code.
It should be also possible to introduce the use of '__builtin_constant_p'
gcc builtin function for an efficient way of checking if 'unit_x' is known
to be zero at compile time (when processing padding pixels for NONE, or
PAD repeat).
Benchmarks from Intel Core i7 860:
== before (nearest OVER) ==
op=3, src_fmt=20028888, dst_fmt=20028888, speed=142.01 MPix/s
== after (nearest OVER) ==
op=3, src_fmt=20028888, dst_fmt=20028888, speed=314.99 MPix/s
== performance of nonscaled operation as a reference ==

PAD repeat support for fast scaling with nearest filter
When processing pixels from the left and right padding, the same
scanline function is used with 'unit_x' set to 0.
Actually appears that gcc can handle this quite efficiently. When
using 'restrict' keyword, it is able to optimize the whole operation
performed on left or right padding pixels to a small unrolled loop
(the code is reduced to a simple fill implementation):
9b30: 89 08 mov %ecx,(%rax)
9b32: 89 48 04 mov %ecx,0x4(%rax)
9b35: 48 83 c0 08 add $0x8,%rax
9b39: 49 39 c0 cmp %rax,%r8
9b3c: 75 f2 jne 9b30
Without 'restrict' keyword, there is one instruction more: reloading
source pixel data from memory in the beginning of each iteration. That
is slower, but also acceptable.

the source with zero pixels). So it's better not to use PIXMAN_REPEAT_NONE
for handling FAST_PATH_SAMPLES_COVER_CLIP special case.

Nearest scaling fast path macro split into two parts
Scanline processing is now split into a separate function. This provides
an easy way of overriding it with a platform specific implementation,
which may use SIMD optimizations. Only basic C data types are used as
the arguments for this function, so it may be implemented entirely in
assembly or be generated by some JIT engine.
Also as a result of this split, the complexity of code is reduced a
bit and now it should be easier to introduce support for the currently
missing NONE, PAD and REFLECT repeat types.

When pixman_compute_composite_region32() returns FALSE, don't fini the region.
The rule is that the region passed in must be initialized and that the
region returned will still be valid. Ie., the lifecycle is the
responsibility of the caller, regardless of what the function returns.
Previously, compute_composite_region32() would finalize the region and
then return FALSE, and then the caller would finalize the region
again, leading to memory corruption in some cases.

Use windows.h directly for mingw32 build
This patch adresses the issue discussed in
http://lists.freedesktop.org/archives/pixman/2010-April/000163.html
There were only two clashing identifiers. The first one is IN, which
obviously causes problems in Pixman for lines like
PIXMAN_STD_FAST_PATH (IN, solid, a8, a8, fast_composite_in_n_8_8),
Fortunately the mingw headers provide a solution: by defining
_NO_W32_PSEUDO_MODIFIERS, these stupid symbols are skipped.
The other name is UINT64, used in pixman-mmx.c. I renamed that
function to to_uint64, but may be another name is more appropriate.

Be more paranoid about checking for GTK+
From time to time people run into issues where the configure script
detects GTK+ when it is either not installed, or not functional due to
a missing pixman. Most recently:
https://bugs.freedesktop.org/show_bug.cgi?id=29736
This patch makes the configure script more paranoid by
- always using PKG_CHECK_MODULES and not PKG_CHECK_EXISTS, since it
seems PKG_CHECK_EXISTS will sometimes return true even if a dependency
of GTK+, such as pixman-1, is missing.
- explicitly checking that pixman-1 is installed before enabling GTK+.

REPEAT_NORMAL is (NO_NONE | NO_PAD | NO_REFLECT).

Replace compute_src_extent_flags() with analyze_extents()
This commit fixes two separate problems: 1. Incorrect computation of
the FAST_PATH_SAMPLES_COVER_CLIP flag, and 2. FAST_PATH_16BIT_SAFE is
a nonsensical thing to compute.
== 1. Incorrect computation of SAMPLES_COVER_CLIP:
Previously we were using pixman_transform_bounds() to compute which
source samples would be used for a composite operation. This is
incorrect for several reasons:
(a) pixman_transform_bounds() is transforming the integer bounding box
of the destination samples, where it should be transforming the
bounding box of the samples themselves. In other words, it is too
pessimistic in some cases.
(b) pixman_transform_bounds() is not rounding the same way as we do
during sampling. For example, for a NEAREST filter we subtract
pixman_fixed_e before rounding off to the nearest sample so that a
transformed value of 1 will round to the sample at 0.5 and not to the
one at 1.5. However, pixman_transform_bounds() would simply truncate
to 1 which would imply that the first sample to be used was the one at
1.5. In other words, it is too optimistic in some cases.
(c) The result of pixman_transform_bounds() does not account for the
interpolation filter applied to the source.
== 2. FAST_PATH_16BIT_SAFE is nonsensical
The FAST_PATH_16BIT_SAFE is a flag that indicates that various
computations can be safely done within a 16.16 fixed-point
variable. It was used by certain fast paths who relied on those
computations succeeding. The problem is that many other compositing
functions were making similar assumptions but not actually requiring
the flag to be set. Notably, all the general compositing functions
simply walk the source region using 16.16 variables. If the
transformation happens to overflow, strange things will happen.
So instead of computing this flag in certain cases, it is better to
simply detect that overflows will happen and not try to composite at
all in that case. This has the advantage that most compositing
functions can be written naturally way.
It does have the disadvantage that we are giving up on some cases that
previously worked, but those are all corner cases where the areas
involved were very close to the limits of the coordinate
system. Relying on these working reliably was always a somewhat
dubious proposition. The most important case that might have worked
previously was untransformed compositing involving images larger than
32 bits. But even in those cases, if you had REPEAT_PAD or
REPEAT_REFLECT turned on, you would hit bits_image_fetch_transformed()
which has the 16 bit limitations.
== Fixes
This patch fixes both problems by introducing a new function called
analyze_extents() that has the responsibility to reject corner cases,
and to compute flags based on the extents.
It does this through a new compute_sample_extents() function that will
compute a conservative (but tight) approximation to the bounding box
of the samples that will actually be needed. By basing the computation
on the positions of the _sample_ locations in the destination, and by
taking the interpolation filter into account, it fixes problem one.
The same function is also used with a one-pixel expanded version of
the destination extents. By checking if the transformed bounding box
will overflow 16.16 fixed point, it fixes problem two.

Extend scaling-crash-test in various ways
This extends scaling-crash-test to test some more things:
- All combinations of NEAREST/BILINEAR/CONVOLUTION filters and
NORMAL/PAD/REFLECT repeat modes.
- Tests various scale factors very close to 1/7th such that the source
area is very close to edge of the source image.
- The same things, only with scale factors very close to 1/32767th.
- Enables the commented-out tests for accessing memory outside the
source buffer.
Also there is now a border around the source buffer which has a
different color than the source buffer itself so that if we sample
outside, it will show up.
Finally, the test now allows the destination buffer to not be changed
at all. This allows pixman to simply bail out in cases where the
transformation too strange.

This patch adds extra guards around our use of
OpenMP pragmas and checks that the pragmas won't
cause link errors. This fixes the build on
Tru64 and Solaris with the native compilers and clang.

Don't trust OpenBSD's gcc to produce working code for __thread.
The gcc on OpenBSD 4.5 to 4.7 at least produces bad code for __thread,
without as much as a warning.

The x888 suggests that they have something to do with the x8r8g8b8
formats, but that's not the case; they are assuming a8r8g8b8
formats. (Although in some cases they also work for x8r8g8b8 type
formats).

test: Make sure the palettes for indexed format roundtrip properly
The palettes for indexed formats must satisfy the condition that if
some index maps to a color C, then the 15 bit version of that color
must map back to the index. This ensures that the destination operator
is always a no-op, which seems like a reasonable assumption to make.

Alexander Shulgin pointed out that underscore-prefixed identifiers are

instead.

Fix conical gradients to match QConicalGradient from Qt
Under the assumption that pixman gradients are supposed to match
QConicalgradient, described here:
http://doc.trolltech.com/4.4/qconicalgradient.html
this patch fixes two separate bugs in pixman-conical-gradient.c.
The first bug is that the output of atan2() is in the range of [-pi,
pi], which means the parameter into the gradient can be negative. This
is wrong since a QConicalGradient always interpolates around the
center from 0 to 1. The fix for that is to (a) make sure the given
angle is between 0 and 360, and (b) add or subtract 2 * M_PI if the
computed angle ends up outside [0, 2 * pi].
The other bug is that we were interpolating clockwise, whereas
QConicalGradient calls for a counter-clockwise interpolation. This is
easily fixed by subtracting the parameter from 1.
Finally, this patch encapsulates the computation in a new force-inline
function so that it can be reused in both the affine and non-affine
case.

Eliminate mask_bits from all the scanline fetchers.
Back in the day, the mask_bits argument was used to distinguish
between masks used for component alpha (where it was 0xffffffff) and
masks for unified alpha (where it was 0xff000000). In this way, the
fetchers could check if just the alpha channel was 0 and in that case
avoid fetching the source.
However, we haven't actually used it like that for a long time; it is
currently always either 0xffffffff or 0 (if the mask is NULL). It also
doesn't seem worthwhile resurrecting it because for premultiplied
buffers, if alpha is 0, then so are the color channels
normally.
This patch eliminates the mask_bits and changes the fetchers to just
assume it is 0xffffffff if mask is non-NULL.

Some of the tests are quite heavy CPU users and may benefit from
using multiple CPU cores, so the programs from 'test' directory
are now built with OpenMP support. OpenMP is easy to use, portable
and also takes care of making a decision about how many threads
to spawn.

This new generalized function can be reused in both blitters-test

it parallelizable (it is a sum of individual 32-bit values returned
by a callback function, which is now responsible for running test-specific
code). Return values may be crc32, some other hash or even just zero on
success and non-zero on error (in this case, the expected result of the
whole test run should be 0).

Fixes for pthread thread local storage.
The tls_name_key variable is passed to tls_name_get(), and the first
time this happens it isn't initialized. tls_name_get() then passes it
on to tls_name_alloc() which passes it on to pthread_setspecific()
leading to undefined behavior.
None of this is actually necessary at all because there is only one
such variable per thread local variable, so it doesn't need to passed
as a parameter at all.
All of this was pointed out by Tor Lillqvist on the cairo mailing
list.

http://sourceware.org/ml/binutils/2008-03/msg00260.html
For pixman the impact is a build failure when using
binutils 2.18. Versions 2.19 and higer are fine. Still
some distros may be using older versions of binutils and
this is causing problems.
This patch workarounds the problem by replacing a problematic
"vmov a, b" instruction with equivalent "vorr a, b, b". Actually
they even map to the same instruction opcode in the generated
code, so the resulting binary is identical with and without patch.

ARM: Use '.object_arch' directive in NEON assembly file
This can be used to override the architecture recorded in the EABI object
attribute section. We set a minimum arch to 'armv4'. Binutils documentation
recommends to use this directive with the code performing runtime detection
of CPU features.
Additionally NEON/VFP EABI attributes are suppressed. And the instruction
set to use is explicitly set to '.arm'.
Configure test for NEON support is also updated to include a bunch of
these new directives (if any of these is unsupported by the assembler,
it is better to fail configure test than to fail library build).
All these changes are required to fix SIGILL problem on armv4t, reported in

Add FAST_PATH_SAMPLES_COVER_CLIP and FAST_PATH_16BIT_SAFE
FAST_PATH_SAMPLES_COVER_CLIP:
This is set of the source sample grid, unrepeated but transformed
completely completely covers the clip destination. If this is set
you can use a simple scaled that doesn't have to care about the repeat
mode.
FAST_PATH_16BIT_SAFE:
This signifies two things:
1) The size of the src/mask fits in a 16.16 fixed point, so something like:
max_vx = src_image->bits.width << 16;
Is allowed and is guaranteed to not overflow max_vx
2) When stepping the source space we're guaranteed to never overflow
a 16.16 bit fix point variable, even if we step one extra step
in the destination space. This means that a loop doing:
x = vx >> 16;
vx += unit_x; d = src_row[x];
will never overflow vx causing x to be negative.
And additionally, if you track vx like above and apply NORMAL repeat
after the vx addition with something like:
while (vx >= max_vx) vx -= max_vx;
This will never overflow the vx even on the final increment that
takes vx one past the end of where we will read, which makes the
repeat loop safe.

In some cases we end up trying to use the STORE_4 macro with an 8 bit

On OS X and other systems that don't have __thread, they expand to a
complicated concoction that uses pthread_once() and
pthread_get/set_specific() to get thread local variables.

Store the operator table more compactly.
The four cases for each operator:
none-are-opaque, src-is-opaque, dest-is-opaque, both-are-opaque
are packed into one uint32_t per operator. The relevant strength
reduced operator can then be found by packing the source-is-opaque and
dest-is-opaque into two bits and shifting that number of bytes.
Chris Wilson pointed out a bug in the original version of this commit:
dest_is_opaque and source_is_opaque were used as booleans, but their
actual values were the results of a logical AND with the
FAST_PATH_OPAQUE flag, so the shift value was wildly wrong.
The only reason it actually passed the test suite (on x86) was that
the compiler computed the shift amount in the cl register, and the low
byte of FAST_PATH_OPAQUE happens to be 0, so no shifting actually took
place, and the original operator was returned.

Date: Fri Sep 18 14:10:31 2009 -0400
Make the operator strength reduction constant time.
By extending the operator information table to cover all operators we
can replace the loop with a table look-up. At the same time, base the
operator optimization on the computed flags rather than the ones in
the image struct.
Finally, as an extra optimization, we no longer ignore the case where
there is a mask. Instead we consider the source opaque if both source
and mask are opaque, or if the source is opaque and the mask is
missing.

Move all code to do debugging spew into pixman-private.
Rather than the region code having its own little debug system, move
all of it into pixman-private where there is already return_if_fail()
macros etc. These macros are now enabled in development snapshots and
nowhere else. Previously they were never enabled unless you modified
the code.
At the same time, remove all the asserts from the region code since we
can never turn them on anyway, and replace them with
critical_if_fail() macros that will print spew to standard error when
DEBUG is defined.
Finally, also change the debugging spew in pixman-bits-image.c to use
return_val_if_fail() instead of its own fprintf().

Eliminate all the composite methods.
They are no longer necessary because we will just walk the fast path
tables, and the general composite path is treated as another fast
path.
This unfortunately means that sse2_composite() can no longer be
responsible for realigning the stack to 16 bytes, so we have to move
that to pixman_image_composite().

Make general_composite_rect() just another fast path.
We introduce a new PIXMAN_OP_any fake operator and a PIXMAN_any fake
format that match anything. Then general_composite_rect() can be used
as another fast path.
Because general_composite_rect() does not require the sources to cover
the clip region, we add a new flag FAST_PATH_COVERS_CLIP which is part
of the set of standard flags for fast paths.
Because this flag cannot be computed until after the clip region is
available, we have to call pixman_compute_composite_region32() before
checking for fast paths. This will resolve itself when we get to the
point where _pixman_run_fast_path() is only called once per composite
operation.

There is not much real benefit in having asserts turned on in

of computing it on each composite invocation.
This patch also computes format codes for images such as PIXMAN_solid,

selected for a 1x1 solid image, when that fast path doesn't actually
understand repeating.

When fetching from an alpha map, replace the alpha channel of the image
Previously it would be multiplied onto the image pixel, but the Render
specification is pretty clear that the alpha map should be used
*instead* of any alpha channel within the image.
This makes the assumption that the pixels in the image are already
premultiplied with the alpha channel from the alpha map. If we don't
make this assumption and the image has an alpha channel of its own, we
would have to first unpremultiply that pixel, and then premultiply the
alpha value onto the color channels, and then replace the alpha
channel.

test: Add new alphamap test program.
This program demonstrates three bugs relating to alpha maps:
- When fetching from an alpha map into 32 bit intermediates, we use
the fetcher from the image, and not the one from the alpha map.
- For 64 bit intermediates we call fetch_pixel_generic_lossy_32()
which then calls fetch_pixel_raw_64, which is NULL because alpha
images are never validated.
- The alpha map should be used *in place* of any existing alpha
channel, but we are actually multiplying it onto the image.

region: Enable or disable fatal errors and selfchecks based on version number
There is a couple of bugs in bugzilla where bugs in the X server
triggered asserts in the pixman region code. It is probably better to
let the X server survive this. (In fact, I thought I had disabled them
for 0.16.0, but apparently not).
The patch below uses these rules:
- In _stable_ pixman releases, assertions and selfchecks are turned
off. Assertions, so that the X server doesn't die. Selfchecks,
for performance reasons.
- In _unstable_ pixman releases, both assertions and selfcheck are
turned on. These releases are what get added to development
distributions such as rawhide, so we want as much self-checking
as possible.
- In _random git checkouts_, assertions are enabled, so that bugs
are caught, but selfchecks are disabled so that you can use them
for performance work without having to fiddle with turning
selfchecks off.

ARM: macro template for single scanline compositing functions
Existing template already supports 2D images processing,
but pixman also needs some NEON optimized functions for
improving performance when compositing is decoupled
into "fetch -> process -> store" stages and done via
temporary scanline buffer. That's why a new simplified
template which deals only with the generation of single
scanline processing functions is handy.

Fix rounding of top and bottom coordinates.
The rules for trap rasterization is that coordinates are rounded
towards north-west.
The pixman_sample_ceil() function is used to compute the first
(top-most) sample row included in the trap, so when the input
coordinate is already exactly on a sample row, no rounding should take
place.
On the other hand, pixman_sample_floor() is used to compute the final
(bottom-most) sample row, so if the input is precisely on a sample
row, it needs to be rounded down to the previous row.
This commit fixes the rounding computation. The idea of the
computation is like this:
Floor operation that rounds exact matches down: First subtract
pixman_fixed_e to make sure input already on a sample row gets rounded
down. Then find out how many small steps are between the input and the
first fraction. Then add those small steps to the first fraction.
The ceil operation first adds (small_step + pixman_e), then runs a
floor. This ensures that exact matches are not rounded off.
Based on a patch by M Joonas Pihlaja.

Fix slightly skewed sampling grid for antialiased traps
The sampling grid is slightly skewed in the antialiased case. Consider
the case where we have n = 8 bits of alpha.
The small step is
small_step = fixed_1 / 15 = 65536 / 15 = 4369
The first fraction is then
frac_first = (small_step / 2) = (65536 - 15) / 2 = 2184
and the last fraction becomes
frac_last
= frac_first + (15 - 1) * small_step = 2184 + 14 * 4369 = 63350
which means the size of the last bit of the pixel is
65536 - 63350 = 2186
which is 2 bigger than the first fraction. This is not the end of the
world, but it would be more correct to have 2185 and 2185, and we can
accomplish that simply by making the first fraction half the *big*
step instead of half the small step.
If we ever move to coordinates with 8 fractional bits, the
corresponding values become 8 and 10 out of 256, where 9 and 9 would
be better.
Similarly in the X direction.

Eliminate the NEED_SOLID_MASK flag
This flag was used to indicate that the mask was solid while still
allowing a specific format to be required. However, there is not
actually any need for this because the fast paths all used
_pixman_image_get_solid() which already allowed arbitrary formats.
The one thing that had to be dealt with was component alpha. In
addition to interpreting the presence of the NEED_COMPONENT_ALPHA
flag, we now also interprete the *absence* of this flag as a
requirement that the mask does *not* have component alpha.
Siarhei Siamashka pointed out that the first version of this commit
had a bug, in which a NEED_SOLID_MASK was accidentally not turned into
a PIXMAN_solid in the ARM NEON implementation.

Use the destination buffer directly in more cases instead of fetching.
When the destination buffer is either a8r8g8b8 or x8r8g8b8, we can use
it directly instead of fetching into a temporary buffer. When the
format is x8r8g8b8, we require the operator to not make use of
destination alpha, but when it is a8r8g8b8, there are no restrictions.

ARM: introduction of the new framework for NEON fast path optimizations
GNU assembler and its macro preprocessor is now used to generate
NEON optimized functions from a common template. This automatically
takes care of nuisances like ensuring optimal alignment, dealing with
leading/trailing pixels, doing prefetch, etc.
Implementations for a lot of compositing functions are also added,
but not enabled.

Define PIXMAN_USE_INTERNAL_API in pixman-private.h

users from setting their own CFLAGS, just define the
PIXMAN_USE_INTERNAL_API and PIXMAN_DISABLE_DEPRECATED in
pixman-private.h

Add fast path scaled, bilinear fetcher.
This adds a bilinear fetcher for the case where the image has a scaled
transformation, does not repeat, and the format {ax}8r8g8b8.
Results for the swfdec-youtube benchmark
Before:
[ # ] backend test min(s) median(s) stddev. count
[ 0] image swfdec-youtube 7.841 7.915 0.72% 6/6
After:
[ # ] backend test min(s) median(s) stddev. count
[ 0] image swfdec-youtube 6.677 6.780 0.94% 6/6
These results were measured on a faster machine than the ones in the
previous commit, so the numbers are not comparable.

Speed up bilinear interpolation.
Speed up bilinear interpolation by processing more than one component
at a time on 64 bit architectures, and by precomputing the dist{ixiy}
products on 32 bit architectures.
Previously bilinear interpolation for one pixel would take 24
multiplications. With this improvement it takes 12 on 64 bit, and 20
on 32 bit.
This is a small but consistent speedup on the swfdec-youtube
benchmark:
[ # ] backend test min(s) median(s) stddev. count
Before:
[ 0] image swfdec-youtube 18.010 18.020 0.09% 4/5
After:
[ 0] image swfdec-youtube 17.488 17.584 0.22% 5/6

As an interim measure, replace AM_INIT_AUTOMAKE([dist-bzip2]) with
AM_INIT_AUTOMAKE([foreign dist-bzip2]). This will prevent the generation
of the INSTALL file. It is also part of the 24206 solution.

convert the index to bit position.

ARM: Remove fallback to ARMv6 implementation from NEON delegate chain
This can help to fix build problems with '-mthumb' gcc option in CFLAGS.
ARMv6 optimized code can't be compiled for thumb (because of its inline
assembly) and gets automatically disabled in configure. Reference
to it from NEON optimized code resulted in linking problems.
Every ARMv6 optimized fast path function also has a better NEON
counterpart, so there is no need to fallback to ARMv6. Shorter
delegate chain should additionally result in a bit better performance.

Work around a Sun Studio 12 code generation bug involving _mm_set_epi32().
Calling a static function wrapper around _mm_set_epi32() when not
using optimisation causes Sun Studio 12's cc to emit a spurious
floating point load which confuses the assembler. Using a macro wrapper

Work around differing _mm_prefetch() prototypes on Solaris.
Sun Studio 12 expects the address to prefetch to be
a const char pointer rather than a __m128i pointer or
void pointer.

Default to optimised builds when using a Sun Studio compiler.
Autoconf's AC_PROG_CC sets the default CFLAGS to -O2 -g for
gcc and -g for every other compiler. This patch defaults
CFLAGS to the equivalent -O -g when we're using Sun Studio's cc
if the user or site admin hasn't already set CFLAGS.

Work around a Sun Studio 12 code generation bug involving _mm_set_epi32().
Calling a static function wrapper around _mm_set_epi32() when not
using optimisation causes Sun Studio 12's cc to emit a spurious
floating point load which confuses the assembler. Using a macro wrapper
rather than a function steps around the problem.

ARM: workaround for gcc bug in vshll_n_u8 intrinsic
Some versions of gcc (cs2009q1, 4.4.1) incorrectly reject
shift operand having value >= 8, claiming that it is out of

_pixman_run_fast_path: typo
This is one example of a compiler warning that was lost amit the build
noise.
The error here is that in a list of required conditions we used ';'
instead of '&&' with the result of continuing to use the fast-path
even if we had a wide mask.
Another error is that it was testing src, not mask as it should.

Test program for stressing the use of different formats and operators
The code and overall method is mostly based on scaling-test. This one
focuses on trying to stress as many different color formats and types
of composition operations as possible.
This is an initial implementation which may need more tuning. Also
not all color format and operator combinations are actually used.
When cpu specific optimizations are disabled, this test provides
identical deterministic results on x86, PPC and ARM.
Script blitters-test-bisect.rb now works in non-stop mode, until
it finds any problem. This allows to run it for example overnight
in order to test a lot more variants of pixman calls and increase
chances of detecting problems in pixman. Just like with scaling-test,
running blitters-test binary alone with no command line arguments
runs a small predefined number of tests and compares checksum
with a reference value for quick verification.

Change bits_image_fetch_transformed() to work one pixel at a time.
Previously, it would generate a buffer of coordinates, then pass that
off to a pixel fetcher, but this caused a large performance regression
with the swfdec-fill-rate-2xfsaa cairo trace.
This is the first step towards fixing that.

Explain how we can simplify the radial gradient computation
Soeren rightfully complained that I had removed all the comments from
André's patch, most importantly that explain why the transformation is
valid. So add a few details to show that B varies linearly across the
scanline and how we can therefore reduce the per-pixel cost of evaluating
B.

Add implementation of MMX __m64 functions for MSVC x64.
Microsoft C++ does not define __m64 and all related MMX functions in
x64. However, it succeeds in generating object files for SSE2 code
inside pixman.
The real problem happens during linking, when it cannot find MMX functions
(which are not defined as intrinsics for AMD64 platform).
I have implemented those missing functions using general programming.
MMX __m64 is used relatively scarcely within SSE2 implementation, and the
performance impact probably is negligible.
Bug 22390.

Only apply the workaround if the clip region extends beyond the drawable.
This works because the X server always attempts to set a clip region
within the bounds of the drawable, and it only fails at it when it is
computing the wrong translation and therefore needs the workaround.

Rework the workaround for bogus X server images.
Bug 22844 demonstrates that it is not sufficient to play tricks with
the clip regions to work around the bogus images from the X
server. The problem there is that if the operation hits the general
path and the destination has a different format than a8r8g8b8, the
destination pixels will be fetched into a temporary array. But because
those pixels would be outside the clip region, they would be fetched
as black. The previous workaround was relying on fast paths fetching
those pixels without checking the clip region.
In the new scheme we work around the problem at the
pixman_image_composite() level. If an image is determined to need a
work around, we translate both the bits pointer, the coordinates, and
the clip region, thus effectively undoing the X server's broken
computation.

ARM: Workaround cs2007q3 compiler bug for NEON registers clobber list
128-bit registers "qX" are incorrectly handled in inline assembly
clobber list for codesourcery cs2007q3 gcc toolchain. Only the
first 64-bit half is saved and restored by gcc. Changing clobber
list to use only 64-bit register aliases can solve this problem.
For example, 128-bit register q0 is mapped to two 64-bit
registers d0 and d1, q1 is mapped to d2 and d3, etc.

- Use GOOD_RECT() instead of magic if statements for funtions that take

- Use GOOD_RECT() in _reset(). The checks in the previous code seemed to
allow an empty box, but then created a broken region from it.

Move workaround logic to pixman-bits-image.c.
Instead of computing whether a workaround is needed on every call to
_pixman_run_fast_path(), just cache this information in the image.
Also, when workarounds are needed, clip against the source geometry to
prevent out of bound reads.

Add workarounds for X servers doing out-of-bounds accesses.
Old X servers rely on out-of-bounds accesses when they are asked
to composite with a window as the source. They create a pixman image
pointing to some bogus position in memory, but then they set a clip
region to the position where the actual bits are.
Due to a bug in old versions of pixman, where it would not clip
against the image bounds when a clip region was set, this would
actually work.
The workaround added by this commit is to try and detect whether a
source drawable is actually a window without a client clip set. Such a
window will generally have a clip region that corresponds exactly to
the hierarchy clip in the server, whereas pixmaps will have a clip
region that is an exact match to the drawable.
When we detect such a window, we allow a fast path to run that would
normally be rejected due to the sources not completely subsuming the
composite region.
Fixed X servers should call the new function
pixman_disable_out_of_bounds_workaround() to disable the workaround.
This was reported in bug 22484.

Update the CRC value in scaling-test.c.
The changes in pixman behavior justifying this are:
- New clipping rules
- Bug fixes in region code. In particular, when
pixman_region_init_rects() is called on these two boxes:
{ 2, 6, 7, 6 }
{ 4, 1, 6, 7 }
it now ignores the first one, which is empty and produces
{ 4, 1, 6, 7 }
Previously, it would produce:
{ 2, 1, 7, 7 }
for some reason.

Change checks for srca == 0 to src == 0
It is not generally correct to bail out just because the source alpha
is 0. The color channels still mig not be and in that case the correct
result is:
s + (1 - srca) * d = s + d
which is not generally 0.

Option -mcpu has higher priority than -march with the current versions

reason why 'arm1136j-s' is used in this patch, it could be any armv6
compatible core.

Fix offset bug in pixman_run_fast_path().
Fast paths should only run when the source images complete cover the
composite region, because otherwise they would be required to sample
the border, and fast paths generally don't know how to do that.
The check for this did not work right because it didn't take the
offset generated by the composite coordinates into account. This
commits fixes that by adding (x, y) coordinates to image cover
indicating the new position of the source in destination coordinates.
Based on this we now compare against the region extents which are
already in destination coordinates.

Remove FLASH_SUBTRACT blend mode.
We may resurrect it later, but leave it out for now, as the closest
thing we have to a spec:
http://www.kaourantin.net/2005/09/some-word-on-blend-modes-in-flash.html
claims that alpha values should be subtracted, whereas real-world flash
files indicate that they shouldn't.

[NEON] Replace Ian's glyph-blitter with a better one.
Each scanline of the destination is bulk-loaded into a cached buffer on
the stack (using the QuadWordCopy routine) before being processed. This
is the primary benefit on uncached framebuffers, since it is necessary
to minimise the number of accesses to such things and avoid
write-to-read turnarounds.
This also simplifies edge handling, since QuadWordCopy() can do a
precise writeback efficiently via the write-combiner, allowing the main
routine to "over-read" the scanline edge safely when required. This is
why the glyph's mask data is also copied into a temporary buffer of
known size.
Each group of 8 pixels is then processed using fewer instructions,
taking advantage of the lower precision requirements of the 6-bit
destination (so a simpler pixel multiply can be used) and using a more
efficient bit-repacking method.
(As an aside, this patch removes nearly twice as much code as it
introduces. Most of this is due to duplication of Ian's inner loop,
since he has to handle narrow cases separately. RVCT support is of
course preserved.)
We measured the doubling of performance by rendering 96-pixel height
glyph strings, which are fillrate limited rather than latency/overhead
limited. The performance is also improved, albeit by a smaller amount,
on the more usual smaller text, demonstrating that internal overhead is
not a problem.

Work around X server bug.
X servers prior to
ebfd6688d1927288155221e7a78fbca9f9293952
relied on pixman not clipping to destination geometry whenever an
explicit clip region was set. Since only X servers set
source_clipping, we can just trigger off of that.

Simplify clipping rule
The new rule is:
- Output is clipped to the destination clip region.
- If a source image has the clip_sources property set, then there
is an additional step, after repeating and transforming, but before
compositing, where pixels that are not in the source clip are
rejected. Rejected means no compositing takes place (not that the
pixel is treated as 0). By default source clipping is turned off;
when they are turned on, only client-set clips are honored.
The old rules were unclear and inconsistently implemented.

pixman: define pixman_have_{mmx,sse2} on 64-bit Linux
The refactoring of pixman removed pixman-sse2.h and pixman-mmx.h in commit
41a9a17e0308f2075bb1bd59c4411e43a67d49ec
(http://cgit.freedesktop.org/pixman/commit/?id=41a9a17e0308f2075bb1bd59c4411e43a67d49ec).
On 64-bit Linux this breaks linking of new programs as well as execution of
existing programs with the following errors:
../pixman/.libs/libpixman-1.so: undefined reference to `pixman_have_mmx'
../pixman/.libs/libpixman-1.so: undefined reference to `pixman_have_sse2'
This patch fixes the issue for me by re-introducing the definitions for these
functions. It might be preferable, though, to create proper trivial static
inline functions instead.

Fix alpha map computation in pixman_compute_composite_region()
According to the RENDER spec, the origin of the alpha map is
interpreted relative to the origin of the drawable of the image, not
the origin of the drawable of the alpha map.
This commit fixes that and adds an alpha-test.c test program.
The only use of alpha maps I have been able to find is in Qt and they
don't use a non-zero alpha origin.

Don't read potentially uninitialized data in pixman_CombineMaskU()
This is mainly to quiet valgrind. The data in question would only be
uninitialized when the corresponding mask pixel was zero, so the end
result is zero in any case.

Fix overflows during trap rasterization. [Bug 16560].
Avoid overflows when rasterizing traps that fall entirely in the space
between the final sample row and the end of the coordinate system, or
in the space between the beginning of the coordinate system and the
first sample row. Such traps don't contain any sample points, so the
top and bottom of the edges can safely be moved to the beginning/end.

Fixed rendering bug for source alpha == 0 in OVER fastpath functions
Handling of the case when source alpha is zero was keeping destination
pixel unmodified. But this is different from how generic path behaves.
For example fbOver(0x00200483, 0x9CAC7E9F) == 0x9CCC82FF and the
destination pixel changes from 0x9CAC7E9F to 0x9CCC82FF in spite
of having zero alpha.

functions depending on the exact type of the image.

Updated scaling test to support rgb565, source clipping, etc.
Now test provides better coverage for various image scaling
cases. Unused byte for x8r8g8b8 format is ignored. Running
the test program without any command line options provides
a PASS/FAIL verdict based on the precalculated crc32 value
for using pixman with all the fastpath functions disabled,
which should simplify testing for correcteness.

Set srcRepeat = False when using fbCompositeSrcScaleNearest
NORMAL repeat was broken (the optimized function can handle repeat operation
itself and can be screwed up if 'pixman_walk_composite_region' tries to help it
by splitting the work into handling multiple separate areas).
Splitting work into handling different areas does not work right for the
transform case (and it is never used for generic path). The point is that this
splitting only has full pixel precision at the moment, while correct blitting
needs to preserve some fractional part in calculations when moving from one
"tile" to another.

Allocate initial array of RegionInfo on the stack.
The region validate() code is frequently called by cairo as it is used to
extract regions from the trapezoids for fast-paths through the drawing
code and also for fast-path clipping and the RegionInfo allocation (as
well as the pixman_rect_alloc during the final union) appears as a hot
spot on application memory profiles.

Optimize rectilinear nearest-neighbour scaling
Add a special case for a source transformation that is only a scale and
preserves rectangular pixels and doesn't rotate the image. Currently, only
SOURCE is special cased, however I plan to do more work in this area as needed.
The biggest advantage the specialization currently has is writing directly to
the destination surface instead of a temporary scanline buffer. However, it is
still pretty unoptimized but I want to keep things simple for now.

Rename the current ARM code to ARM SIMD
This code is only for CPUs supporting the SIMD instructions, not for all ARM
CPUs.
I stumbled above the recent commit with the ARM SIMD code while preparing a
patch that models the patch from #13445 after the MMX and SSE2 cases:
The ARM SIMD option currently uses --disable-arm, although this code is only
for CPUs >= ARMv6. That's as if one would call the option to disable the SSE2
code --disable-x86.
This patch therefore renames the configure option and the function and file
names to arm-simd/arm_simd.

'force_inline' and replace all existing uses of 'inline' as a forced inline
with 'force_inline'.

unswitch red and blue
The previous code assumed a color format of ABGR when naming the
variables. The true color format is ARGB. This did not cause any bugs
because no functions rely on the order of colors so far. This patch
renames the variables just to avoid confusion.

Fix for bug 17824

Move _mm_empty() to correct place
The "fbComposeSetupSSE2()" function is guarding most of its code
depending on the capabilities of the CPU, but unfortunately the call
to "_mm_empty()" is not part of this code path but executed
unconditionally. This results in a "illegal instruction" crash on
non-MMX / non-SSE capable CPUs caused by the the "emms" instruction
(embedded in "_mm_empty()").
Fix bug 17729.

Inline fetch functions in pixman-transformed.c
There was significant performance overhead associated with indirect
call to the fetch functions, so inline them.
Also, the old code assumed that if the number of rectangles in the
source clip was 1, then the clip was identical to the image
boundaries. Fix that by running a full region_contains_point()
whenever the source clip is different from pict->common.full_region.
Based on a patch from Antoine Azar.

Add a lossy 32-bit generic pixel fetch function for wide surfaces.
The transformed fetch path currently only works at 32-bit precision. Until a
wide version of that function is added, we need to have a path to perform a
wide FetchPixel and then contract it down to a8r8g8b8.
Also, use the right format when expanding the result in fbFetchTransformed64.
fbFetchTransformed returns a8r8g8b8 results.

Take the source format into account in pixman_expand.
Extract the original bits of the source image for each component and then
replicate up to 16 bits to fill the wide components. Make sure to hard-code the
alpha value to 1 if the source format didn't have alpha.

Date: Fri Jun 6 18:05:15 2008 -0700
Add wide source picture, external alpha, and transformed image routines.
The wide external alpha path should work correctly with wide formats. The wide
transformed fetch code for now just does a 32-bit fetch and then expands, which
will lose precision. Source pictures, for now, are evaluated at depth 32 and
then are expanded to depth 64. We could get higher precision by evaluating them
directly at depth 64, but this should be good enough for now.

Work around GCC bug causing crashes in Mozilla with SSE2
When using SSE2 intrinsics, gcc assumes that the stack is 16 byte
aligned. Unfortunately some code, such as Mozilla and Mono contain
code that aligns the stack to 4 bytes.
The __force_align_arg_pointer__ makes gcc generate a prologue that
realigns the stack pointer to 16 bytes. Fix bug 15693.

Replace hardcoded numbers and uint*_t in combine.inc.
The masks and shifts have been replaced with preprocessor defines generated by
combine.pl. The uint*_t types have been replaced with comp4_t, comp2_t, and
comp1_t depending on how many components the value is supposed to hold.

Fix the SSE related AMD64 build breakage
The introduction of pixman_have_sse() copied the #ifdef __amd64__
found around pixman_have_mmx() in pixman-mmx.c but didn't include the
equivalents of the macros in pixman-mmx.h. As a result, the AMD64 link
fails because the pixman_have_sse() function doesn't exist.
I also introduced header inclusion guards to pixman-mmx.h and
pixman-sse.h while I was at it.

Add rounding epsilon for NEAREST filter after transformation, not before.
For nearest filtering, the transformed location must be rounded to the
nearest sample. For locations that precisely in the middle between two
samples, we round down by adding -epsilon to the coordinates.
Before, we would do this on untransformed coordinates. This patch
changes it to happen after transformation. It also clarifies the
difference between sample locations and rounding.

[pixman-image] [mlk] Free the locally allocated bits.
If we fail to allocate the image, remember to free the bits if we have
created the buffer on behalf of the caller.

[pixman-image] Avoid a potential malloc(0).
Do not attempt to allocate bits if either the image width or height is
0 - Cairo has a habit of attempting to create such surfaces when
generating glyphs. The malloc(0) may return a NULL pointer and be treated
as an out-of-memory error.

Fix special case selection when the mask has a transform

was a mismerge that avoided setting the maskTransform condition when the mask
has a transform. This allowed a special case routine to be chosen when the
mask had a transform, which is not expected by the special case routines.

rasterize traps that extend outside of the image bounds correctly
Traps that extend outside of the image bounds are rasterized incorrectly
currently; the problem is a signed vs. unsigned comparison that got
introduced when a width parameter went from int -> uint. This patch
puts it back to int (since it's stored as an int in the bits structure
to begin with), and also fixes a similar warning in the memset wrapper

Remove unnecessary wrapping from fbFetch/fbStore.
These functions fetch from a picture to a scanline buffer, or store

Don't skip fbFetch/fbStore when PIXMAN_FB_ACCESSORS is enabled.
pixman_composite_rect_general_accessors skips the fetch / store steps by setting
store to NULL when the op is ADD or OVER and the dest format is [ax]8r8g8b8.
This optimization is only valid when no accessors are in play.

Optimize fill rectangles in the op=PIXMAN_OP_CLEAR case

Use the general code in some cases even when a fast path is available
If src or mask are repeating 1x1 images and srcRepeat or
maskRepeat are still TRUE, it means the fast path we
selected does not actually handle repeating images.
So rather than call the "fast path" with a zillion
1x1 requests, we just use the general code (which does
do something sensible with 1x1 repeating images).
