--- Comment #3 from Mark Millard <markmi@dsl-only.net> ---
https://llvm.org/bugs/show_bug.cgi?id=3D26605 got its fix in llvm's 261422 =
check
in.

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.]
