emerge --info
I can only reproduce if I add -flto=thin to a amd64 build (x86 not using this asm, so). Builds fine otherwise, I did have to add USE=o-flag-munging though. This should really go upstream. I did test without -flto=thin, but I didn't check if the error was any different (emerge --keep-going). Looks like it just turns into https://bugs.gentoo.org/707330. Is it worth opening -flto* bugs here? (In reply to Theo Anderson from comment #4) > I did test without -flto=thin, but I didn't check if the error was any > different (emerge --keep-going).

Yes, that's what USE=o-flag-munging I mentioned fixes. > Is it worth opening -flto* bugs here? clang/lld issues alone doesn't seem so bad (to me), but lto or other exotic flag may be a bit much to ask for. Worse if it's asm issues. Not that I can speak for every maintainers. Still better to try and get these fixed upstream though, unless it's an issue gentoo is introducing. Closing as fixed in 1.9.1 |
