            Bug ID: 35344
           Summary: assertion triggers while trying to build the userspace
                    part of FreeBSD on sparc64
           Product: clang
           Version: 5.0
          Hardware: Sun
                OS: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P
         Component: LLVM Codegen
          Assignee: unassignedclangbugs at nondot.org

archive with prepocessed source and run script

While FreeBSD doesn't officially support building with clang on sparc64, I
thought I'd give it a try to see how much works, and how much doesn't.
Unfortunately, an assertion in the compiler itself triggers (see below). I've
attached the preprocessed source and the run script. Please let me know if you
need more information.
