I've tried to migrate to the new profile "default/linux/amd64/23.0/split-usr/desktop" and wasn't able to do it because gcc compilation was failed. I've found that the reason is that I have USE="graphite" enabled for gcc. On 17.1 profile it compiles fine, but on 23.0 it fails on stage2 and stage3 comparison. Looks like the problem in enabling graphite together with one of the new flags enabled in the new profile by default. Reproducible: Always Steps to Reproduce: 1. Switch to 23.0 profile 2. Enable USE=graphite for gcc 3. emerge -1 gcc Actual Results: Emerge fails Expected Results: Emerged successfully
Please share the full build.log, the gcc-build-logs tarball the GCC ebuild creates, and emerge --info.

Your CPU is big.little. I added a workaround in the eclass for that yesterday -- please emerge --sync and try again?
*** This bug has been marked as a duplicate of bug 927641 ***
I've synced and tried to compile gcc again. And it still fails. It looks like it doesn't related to USE=graphite as I initially thought. It fails with USE=-graphite as well. Should I provide more info?

Ok, just let me know if you want me to test it when it will be ready, or any other help.
The bug has been referenced in the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=e897f91e8e81b8168e7045db2f6d8dd9ebdb9ddf commit e897f91e8e81b8168e7045db2f6d8dd9ebdb9ddf Author: Sam James <sam@gentoo.org> AuthorDate: 2024-03-24 17:19:46 +0000 Commit: Sam James <sam@gentoo.org> CommitDate: 2024-03-24 17:47:08 +0000 toolchain.eclass: abort if hybrid CPU detected w/ -march=native Unfortunately, the previous approach can't work. --param doesn't fully wipe out the previous value added by -march=native, so we still get a failed comparison. Users hitting this should install app-misc/resolve-march-native, run resolve-march-native, and use that in their *FLAGS instead of -march=native - at least for sys-devel/gcc via package.env, if not in make.conf. Therefore, our only real option is to just abort when we detect a problematic situation and tell users what to do. The only other idea I had was to try taskset in src_compile which feels super brittle and not sure it'd even work at all. Thanks to Andrei for testing and debugging with us on IRC & the bug.

(Either wait until it hits your mirror or manually apply it to the eclass?)
(In reply to Sam James from comment #10) > Thanks! Could you try out that bit I just pushed? (Either wait until it hits > your mirror or manually apply it to the eclass?) $ resolve-march-native -march=alderlake -mabm -mno-cldemote -mno-kl -mno-pconfig -mno-sgx -mno-widekl -mshstk --param=l1-cache-line-size=64 --param=l1-cache-size=48 --param=l2-cache-size=25600 Is it better to put all of these flags to CFLAGS, or -march=alderlake is enough?
Ok, after changing CFLAGS to resolve-march-native output gcc compiled successfully with USE=graphite. BTW, shouldn't this page be updated as well? https://wiki.gentoo.org/wiki/Safe_CFLAGS
