Comment (by kallisti5):
{{{
09:34 < umccullough> kallisti5, so you can use -mtune=i586 or
-mtune=pentium
09:35 < umccullough> hopefully the mmx/sse code is in ASM
09:36 < umccullough> or, just use -mtune=generic i guess
09:36 < umccullough> but that one is ambiguous IMO
09:36 < umccullough> sounds like it targets i686
09:38 < umccullough> or, you can -march=i586 -mtune=i686 which hopefully
makes compatible code that tries to optimize for 686
09:39 < umccullough> on gcc2, i think it's a little muddier
09:42 <@DeadYak> umccullough: that's precisely what it does, on gcc2
that'd be -march=pentium -mcpu=pentiumpro
09:43 * kallisti5 takes notes
09:43 <@DeadYak> -march restricts the instruction set it's allowed to use,
-mcpu/-mtune tries to fine tune for that particular model and up's
pipelines within the constraints of -march
