RE: How to detect user uses -masm=intel?

[unlvsur unlvsur <unlvsur@live.com>]

What I mean is that what macro GCC sets when it compiles -masm=intel


Int main()
{
#ifdef /*__INTEL_ASM????*/
                printf(“intel”);
#else
                printf(“at&t”);
#endif
}

Inside the inline-asm you can use the alternative.
Like this:
cmp{b}\t{%1, %h0|%h0, %1}

This is how GCC implements this inside too.

Thanks,
