I have successfully built both clang:11 and libomp-11.0.0 with -flto. It's only llvm:11 that fails. It seems to build a broken llvm-tablegen binary which then crashes during the build when...

I can also confirm that building llvm:11 with all flags from this overlay: CFLAGS="-march=znver1 **-O3 -fgraphite-identity -floop-nest-optimize -fdevirtualize-at-ltrans -fipa-pta -flto=4 -fuse-linker-plugin** -pipe -fomit-frame-pointer **-fno-finite-math-only** -Wl,-O1" works as long as I...

Unfortunately I don't think you get any speedups when using distcc with LTO though. It seems like the linking step runs locally and it probably needs to. Otherwise I would...

@shelterx Are you sure you actually built llvm with -flto though? Because of this issue: https://github.com/InBetweenNames/gentooLTO/issues/619 -flto is actually stripped from the llvm package in this overlay: `/etc/portage/package.cflags/lto.conf:sys-devel/llvm *FLAGS-=-flto* #...

@shelterx This is quite interesting. I might do some of my own tests on these packages later. I have a 4 core weak AMD system used as a server and...

Meson 0.62.1 was released on the 23rd of April and has also been in the unstable Gentoo tree for quite a while. Unfortunately though this fix was not included there...

Meson 0.62.2 has been released but it still fails to build gst-plugins-good. Latest meson-9999 still builds it without any issues.

meson-0.63.0 has been released to gentoo unstable and it successfully builds gst-plugins-good for me with LTO enabled
