https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=281765 Bug ID: 281765 Summary: llvm - ThinLTO never uses more than a single thread by default Product: Base System Version: 14.1-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: diizzy@FreeBSD.org CC: brooks@FreeBSD.org, dim@FreeBSD.org, pkubaj@FreeBSD.org Maybe I'm missing something obvious/intentional but according to upstream documentation [1] it should default to one thread per physical core but at least I have never seen that happen on various amd64 and aarch64 systems. Addin -Wl,--thinlto-jobs=N to LDFLAGS makes it work as expected though. 1: https://clang.llvm.org/docs/ThinLTO.html -- You are receiving this mail because: You are the assignee for the bug.help
