I think you attached the wrong config.log file. Please attach this file: > /var/tmp/portage/sys-devel/gcc-13.3.1_p20240614/work/build/x86_64-pc-linux-musl/libgcc/config.log

Created attachment 898300 [details] emerge--info lto Here is my emerge --info as well. Given the error in config.log, my first guess was some kind of incompatibility caused by LTO. OP doesn't seem to have LTO enabled, however, and I'm getting the same errors with LTO off. Maybe OP is using LTO elsewhere?
I'm 99% sure you have to use GNU binutils right now for GCC.

OP, we need /var/tmp/portage/sys-devel/gcc-13.3.1_p20240614/work/build/x86_64-pc-linux-musl/libgcc/config.log and gcc-build-logs.tar.xz.
I re-installed sys-devel/binutils and that solved this issue on my end.
See https://briancallahan.net/blog/20240122.html for how we could fix this eventually.
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=d99053c9327d72eb0e13de964b0b79355caebc5b commit d99053c9327d72eb0e13de964b0b79355caebc5b Author: Sam James <sam@gentoo.org> AuthorDate: 2024-09-11 22:17:22 +0000 Commit: Sam James <sam@gentoo.org> CommitDate: 2024-09-11 22:20:19 +0000 toolchain.eclass: depend on sys-devel/binutils:* GCC doesn't build in Gentoo at least without GNU Binutils. It is possible but it requires some work. It's not clear to me if some of that work needs to happen in LLVM upstream too (see below). In commits 7011340a0f13dcada6f3be48054957035bc6e01a and a7c27596827072f586dc07e6d53531ecb2c7cd6e, I tried to get things building with Clang's assembler but didn't get it over the line. I think I remember Arfrever and I coming up with a few later drafts (?) on IRC in #gentoo-hardened but I didn't commit any of it as it didn't work in the end anyway. But see https://briancallahan.net/blog/20240122.html which tackles at least one of the issues I ended up hitting before. In any case, add the dependency for now to keep things working.
