how to see cpp(C preprocessor) output for a file?

[ckim at etri.re.kr]

Hello,

Is there any way I can see the cpp output of a file (for example
arch/arm/lib/vsprintf.c) after the build? (in the Makefile option for
example)

I see some code not executed though I think I have all the configs for the
lines.

Thanks!
