On Fedora 20/x86-64, I got

/export/gnu/import/git/llvm/tools/clang/test/CodeGen/mips-unsigned-extend.c:13:9:
error: expected string not found in input
// N64: call void @foo(i32 signext %0)
        ^

; ModuleID = '/export/gnu/import/git/llvm/tools/clang/test/CodeGen/mips-unsigned-extend.c'
^
<stdin>:17:2: note: possible intended match here
 call void @foo(i32 signext %1)
