https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=207175 --- Comment #3 from Mark Millard <markmi@dsl-only.net> --- https://llvm.org/bugs/show_bug.cgi?id=26605 got its fix in llvm's 261422 check in. But it is going to be some time [weeks or months] before I again have access to the powerpcs that I had been using. I'm not currently set up to check 11.0 -r310975 on powerpc's [or powerpc64's]. I expect that this specific issue is fixed. [But I'll note that there are many other problems for powerpc [and powerpc64] code generation via clang. For powerpc it does not follow the stack handling part of the expected ABI correctly. Testing the fix involves sidestepping the ABI requirement so that clang's generated code is tolerated. With such work arounds I've only gotten as far as buildworld being clang based, not buildkernel.] -- You are receiving this mail because: You are the assignee for the bug.
