Extended Description

Works:

thakis@ubu:~$ cat test.S
.warning "Here be dragons"

thakis@ubu:~$ arm-linux-gnueabihf-g++ -c test.S
test.S: Assembler messages:
test.S:1: Warning: Here be dragons

But:

$ ~/src/llvm-build/bin/clang -target arm-linux-androideabi -c test.S
test.S:1:1: error: unknown directive
.warning "here be dragons"
^

This is used in openmax.

(would be nice if there was some driver flag to suppress .warning diagnostics if this gets implemented)

No driver flag for the warning though. The assembler diagnostics code looks generally unfinished (it ignores clang's -fcolor-diagnostics for example); maybe I'll poke at that at some point.
