           Summary: Regression(r236060): Building .S files in android asan
                    mode is broken
           Product: clang
           Version: trunk

          Priority: P

Used to work. Now:

error:
/usr/local/google/home/thakis/src/llvm-build/bin/../lib/clang/3.7.0/lib/linux/libclang_rt.asan-arm-android.so
uses VFP register arguments, output does not

(libclang_rt.asan-arm-android.so was built with the same clang as the output
files, but possibly with different fp flags.)
