So you have also hit that bug ?
http://public.kitware.com/Bug/view.php?id=8392
Can you please try the attached patch ?
It introduces a language "ASM-GCC" and removes the extension ".S" from the
normal assembler support.
Can you please give it a try ?
Is it only gcc which supports processing assembler files or do other compilers
also support this ?
