Hi, seems I am not the only one who runs Gentoo on a relatively memory-constrained machine with 2GB RAM virtual. I cannot bootstrap gcc-12 too, for a looong while. Manually I can get around by -O0 but I screwed up something and the resulting binries from step 2 and 3 differ: emerge -uN sys-devel/gcc [wait for error-exit] pushd

You cannot manually run part of the build process with different flags because then the comparison will fail with when that file got built earlier. Anyway, I suggest, for now (until the GCC upstream change is made): 1. Drop -pipe from *FLAGS 2. Add -Wl,--no-keep-memory to LDFLAGS
(In reply to Sam James from comment #4) > You cannot manually run part of the build process with different flags > because then the comparison will fail with when that file got built earlier. I just tried hoping the Makefiles are are correctly and do not rely on env variables. I know it was not correct and hence I mentioned that explicitly. although it was not main problem itself. > Anyway, I suggest, for now (until the GCC upstream change is made): > 1. Drop -pipe from *FLAGS > 2. Add -Wl,--no-keep-memory to LDFLAGS Wow, works, thank you!
I don't plan on backporting this to 12, but: commit 1f1f22257a2af5095f008ed5e6d48330024a24c7 Author: Sam James <sam@gentoo.org> Date: Mon Oct 16 13:40:03 2023 +0100 sys-devel/gcc: "backport" insn-emit split patches to 14.x (14.0.0_pre20231015) Done for parity with 13.x. This is a continuation of 7a6b2d23ec02e75475a6123254ccd44d73827f39 ('13.2.0: backport split match.pd changes') in a sense - see that commit for rationale for backporting. Motivated here again by more reports of OOMs with insn-match.cc.
