Description Mart Raudsepp gentoo-dev 2025-01-08 23:06:55 UTC
ld.lld: error: inconsistent LTO Unit splitting (recompile with -fsplit-lto-unit)

Previous working one was www-client/chromium-128.0.6613.113 from before new rust eclasses.

On top of emerge --info, chromium gets -mbranch-protection=pac-ret added to CFLAGS/CXXFLAGS, because my default -mbranch-protection=standard breaks (or used to) chromium due to its JIT not being BTI compatible. The user patch is about the same thing. The other user patch is one Kangie had me try to remove one of the conditionals about rust supporting -Zsplit-lto-unit or something without it affecting the end result.
