Same here.

And additionally the mips-unsigned-ext-var.c test fails:

 clang/test/CodeGen/mips-unsigned-ext-var.c:5:10: fatal error: 'stdarg.h'
file not found
 #include <stdarg.h>

          ^

 1 error generated.

 FileCheck error: '-' is empty.



Could you please fix the issue or revert the commit?

Thanks!
