Re: CPU flags?

[Paul THOMAS]

Paul,

Do you mean the values that -march and -mcpu-type can take on?  I have:

# CPU types supported in gcc-3.2 and higher: athlon-xp, athlon-mp, athlon-4,
# athlon-tbird, athlon, k6, k6-2, k6-3, i386, i486, i586 (Pentium), i686
# (PentiumPro), pentium, pentium-mmx, pentiumpro, pentium2 (Celeron), pentium3,
# and pentium4. ( from http://www.linuxquestions.org/questions/archive/40/2004/06/2/192003 )
