GCC with graphite loop optimization stopped working after upgrading dev-libs/isl to 0.15. I tried to recompile GCC, but it failed with errors like /home/gentoo/tmp/portage/sys-devel/gcc-5.1.0/work/gcc-5.1.0/gcc/graphite-poly.h:102:11: error: ‘isl_options_set_schedule_fuse’ was not declared in this scope According to https://gcc.gnu.org/install/prerequisites.html ISL 0.14 (or 0.12.2) is required for graphite loop optimization. Reproducible: Always
no, the whole point of the code is to support multiple versions of isl. we do not want to pin the versions in gcc. also, you must post `emerge --info` and full build logs as attachments for all of your bug reports.

If it helps you, I'll attach the build.log of sys-devel/gcc-5.1. Another thing which hit me several times: when ISL is upgraded to an new slot/so name, gcc stops working. Would it be possible to have a slot dependency on ISL in the GCC ebuilds, so that an upgrade of ISL would trigger a remerge of GCC (like gentoo does for poppler and libreoffice e.g.)?

can we upgrade this to a major or critical bug? The gcc-5.1.0 ebuild should certainly be modified to not allow new isl to pull in. I can't downgrade to older isl with gcc-5.1, getting error: configure: error: gmp library not found GCC-4.9.2 needs older isl and cloog to build, so I'm effectively stuck with a system I can't modify my toolchain on, which is sort of a critical problem. Will try building a new gcc-5.1 without graphite support and maybe will be back to a usable toolchain.
(In reply to Joe Kappus from comment #5) you're using a compiler that isn't even in ~arch yet, so no, major/critical status doesn't make sense. you should be able to switch to older compilers using gcc-config at any time. further, isl only causes problems w/gcc itself if you try to use graphite related flags ... if that's broken, then don't use them.
should be all set now in the tree; thanks for the report! Commit message: Fix building with isl-0.15 http://sources.gentoo.org/sys-devel/gcc/gcc-5.1.0.ebuild?r1=1.4&r2=1.5
updated the dlopen patch to handle the new version: http://sources.gentoo.org/gentoo/src/patchsets/gcc/5.1.0/gentoo/74_all_gcc5_isl-dl.patch?r1=1.1&r2=1.2 had to port gcc itself too in some places: http://sources.gentoo.org/gentoo/src/patchsets/gcc/5.1.0/gentoo/75_all_gcc5-isl-0.15.patch?rev=1.1
There was a follow up on the GCC mailinglist https://gcc.gnu.org/ml/gcc-patches/2015-07/msg01506.html. Upstream combined the two patches and commited them as https://gcc.gnu.org/git/?p=gcc.git;a=patch;h=a26dad6a5955ed8574efc8d149faca3963a48d46. Perhaps you want to adjust your patch.
i'm aware as i was cc-ed on the patches. all the patches were against the master branch though, so they don't really apply to the gcc-5 branch.
This bug is marked as RESOLVED FIXED but it still seems to apply. I cannot compile either gcc-5.2.0 or gcc-4.9.3 with USE="graphite" using isl-0.15. Both builds fail, using gcc-5.2.0 compiled without graphite, and produce the following errors: graphite-optimize-isl.c In file included from /tmp/portage-acc/tmp/portage/sys-devel/gcc-5.2.0/work/gcc-5.2.0/gcc/graphite.c:88:0: /tmp/portage-acc/tmp/portage/sys-devel/gcc-5.2.0/work/gcc-5.2.0/gcc/graphite-poly.h:398:43: error: 'isl_constraint' has not been declared extern void print_isl_constraint (FILE *, isl_constraint *); /tmp/portage-acc/tmp/portage/sys-devel/gcc-5.2.0/work/gcc-5.2.0/gcc/graphite-poly.h:402:35: error: variable or field 'debug_isl_constraint' declared void extern void debug_isl_constraint (isl_constraint *); /tmp/portage-acc/tmp/portage/sys-devel/gcc-5.2.0/work/gcc-5.2.0/gcc/graphite-poly.h:402:35: error: 'isl_constraint' was not declared in this scope /tmp/portage-acc/tmp/portage/sys-devel/gcc-5.2.0/work/gcc-5.2.0/gcc/graphite-poly.h:402:51: error: expected primary-expression before ')' token extern void debug_isl_constraint (isl_constraint *); ...
