https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=257124 --- Comment #10 from Mikhail Teterin <mi@FreeBSD.org> --- > The problem is that once you start inlining It is my understanding, that "inline" is a hint (as is/was "register")... If compiler knows, the target architecture cannot handle it, it will/should skip it. > Perhaps, although I suspect there will not be a lot of interest Ok, so we agree, that it is a clang/llvm bug and what's left is to figure out, what to do about it. > investigating i386-specific optimization issues Sad... i386 is still listed as Tier-1 in 11. and 12., becoming Tier-2 in 13. https://www.freebsd.org/platforms/ I wonder, what LLVM's stance on this is. > I believe it is disabled by default on all archs right now? Yes, it is, you're right. I'd say, it can be enabled by default, where known to work, and marked with warning elsewhere. But not REMOVED altogether. > I'm sure nobody will use an ancient i386 only machine There are valid reasons to use i386 even on modern processors -- such as, for example, as a small-memory (under 4Gb) VM in a large (64-bit) host. -- You are receiving this mail because: You are the assignee for the bug.help
