While trying out the new GRAPHITE optimizations (rice burning..) I found that a number of packages has problems. GCC is definitely to blame for this one: while compiling libcaca you get an ICE right at the beginning. Reproducible: Always Steps to Reproduce: 1. Turn on loop optimizations: -O3 -floop-strip-mine -floop-block -floop-interchange -ftree-loop-distribution -ftree-loop-im 2. Emerge libcaca 3.

Thanks for the gcc 4.4 test report, assigning to toolchain
Same problem with GCC 4.4.1.
Seems to be this one: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40157
nice work.
will not be fixed in 4.4 according to upstream. keeping this open in case another distro backports a fix from 4.5.
(In reply to comment #6) > will not be fixed in 4.4 according to upstream. keeping this open in case > another distro backports a fix from 4.5. > How about tracking the affected packages, and removing floop-block from the CFLAGS in the ebuilds? Just a thought. I'm having this issue with: media-libs/libcaca-0.99_beta16-r1:0 media-libs/celt-0.7.0 Or should I open a new bug for the purpose? Not entirely sure of the etiquette for such a thing. That is, am I hijacking this bug by suggesting this, or is this the right place to do so?
For what it's worth, starting with the following CFLAGS, simply removing -floop-block allows libcaca to build, whereas celt failed with any of -floop-interchange -floop-strip-mine -floop-block enabled. It builds fine with all three of these removed: CFLAGS='-O2 -march=pentium4 -floop-interchange -floop-strip-mine -floop-block -pipe' Tested with gcc (Gentoo 4.4.2 p1.0) 4.4.2 on x86, and the following: media-libs/libcaca-0.99_beta16-r1:0 media-libs/celt-0.7.0
Marking this as WONTFIX unless someone else backports the patch. Even then, I wouldn't really want to apply it since upstream never plans on doing it for 4.4.
