[cfe-dev] Print assembly output of a compiled file from clang

[Kim Gadecki via cfe-dev]

Hey guys,

I tried the following at the command prompt:

F:\Clanggit\build\32\debug\bin>clang++ source.cpp -v -S -masm=intel

I'm expecting this to output the assembly for my compiled source.cpp 
translation unit but I don't get anything. Any ideas?

Thanks,
Kim
