            Bug ID: 215107
           Summary: head -r309656 clang 3.9.0 for TARGET_ARCH=powerpc:
                    -mminimal-toc rejected (missing llvm 19098 ix?)
           Product: Base System
           Version: CURRENT
          Hardware: powerpc
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: markmi at dsl-only.net

llvm 19098 has a comment that says:

-mlongcall added in r280040/r280041

but the original submittal also requested
-mminimal-toc so the Resolved status
of 19098 might be that both were covered.

Another issue might be powerpc-only vs.
both powerpc64 and powerpc.

As for what happened when trying to build
head -309656 (after bypassing the rejection of
of some BOOK E instructions in hwpmc). . .
