            Bug ID: 43651
           Summary: Add support to -Wa,-W in clang
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P

Currently clang does not support -Wa,-W.

$ cat test.c 


int main () {return 0;}
$ clang -Wa,-W test.c 
clang: error: unsupported argument '-W' to option 'Wa,'



>From man page of GNU as:

       -W
       --no-warn
           Suppress warning messages.

We need this option for gcc compability.
