Without the bloated cplus_demangle from binutils, i.e building with:
$ make NO_DEMANGLE=1 O=~acme/git/build/perf -j3 -C tools/perf/ install
Before:
text data bss dec hex filename
471851 29280 4025056 4526187 45106b /home/acme/bin/perf
After:
[acme@doppio linux-2.6-tip]$ size ~/bin/perf
text data bss dec hex filename
446886 29232 4008576 4484694 446e56 /home/acme/bin/perf
So its a 5.3% size reduction in code, but the interesting part is in the git
diff --stat output:
19 files changed, 20 insertions(+), 1909 deletions(-)
If we ever need some of the things we got from git but weren't using, we just
have to go to the git repo and get fresh, uptodate source code bits.

/* Help to copy the thing properly quoted for the shell safety.

* any single quote is replaced with '\'', any exclamation point
|

* is replaced with '\!', and the whole thing is enclosed in a
|
|
* single quote pair.
|
|
*
|
|
* For example, if you are passing the result to system() as an
|
|
* argument:
|
|
*
|
|
* sprintf(cmd, "foobar %s %s", sq_quote(arg0), sq_quote(arg1))
|
|
*
|
|
* would be appropriate. If the system() is going to call ssh to
|
|
* run the command on the other side:
|
|
*
|
|
* sprintf(cmd, "git-diff-tree %s %s", sq_quote(arg0), sq_quote(arg1));
|
|
* sprintf(rcmd, "ssh %s %s", sq_util/quote.host), sq_quote(cmd));
|
|
*
|
|
* Note that the above examples leak memory! Remember to free result from
|
|
* sq_quote() in a real application.
