But it is going to be some time [weeks or months] before I again have acces= s 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 powerpc6= 4] code generation via clang. For powerpc it does not follow the stack handling part of the expected ABI correctly. Testing the fix involves sidestepping t= he 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.] --=20 You are receiving this mail because: You are the assignee for the bug.=
