into the package, or (b) keep the patch, and further patch install.rs/step.rs
so that install_std() takes a single "target" parameter; test this.
Long build time
===============
* Seems to be fixed with 1.17.0 and rustbuild.
* Try to investigate the 1 hour vs 7 hour build time difference we saw between
git diff debian/1.13.0+dfsg1-2..debian/1.14.0+dfsg1-1 -- debian
<eddyb> infinity0: LLVM [in Rust]?
<eddyb> infinity0: ./configure --enable-debug has this annoying detail that nobody has fixed yet, that it disabled optimizations
<eddyb> so you always have to add --enable-optimize or something like that to counteract the negative effect
<eddyb> unoptimized rustc is *very* slow, in fact it's my sole guess for 7 hours, assuming you didn't just simply lose 8x parallelism or something
<eddyb> infinity0: -Z time-passes between two different compilers, on the same test, would also be pretty revealing
<eddyb> infinity0: also try timing the entire compile-fail test run between stage1/bin/rustc and stage2/bin/rustc (the latter is what running tests uses by default)
<eddyb> infinity0: in the old thing [pre-rustbuild makefiles] it's... make check-stage1-cfail, I think
Older backlog
