Re: [PATCH] Pass -mtune and -march options to assembler.

I think your best choice would be to use the build-time autoconf tests to
decide if we think we're talking to GNU as, and pass the options in that case,
or not if not, optionally with a new command-line switch to override the default.

What about different choice - add information about options to assembler file.
Alternatives:

# COMMAND_LINE gcc -o test.c test.c -O2 -mtune=core2

or

.ident COMMAND_LINE gcc -o test.c test.c -O2 -mtune=core2

What's better?
