(Happily, gcc-4.3 is an improvement there, but it's still worse than 2.95.) Oddly, this one does better with athlon-xp tuning. /proc/cpuinfo info pic? tune [t_34/t_295, t_401/t_295, t_43/t_295] cpu family 6,model 11, Intel(R) Pentium(R) III CPU - S 1266MHz, -fPIC tune=pentium3 [1.37, 1.72, 1.20] cpu family 6,model 11, Intel(R) Pentium(R) III CPU - S 1266MHz, -fPIC tune=athlon-xp [2.16, 2.49, 1.10] I'm not sure how important Pentium III performance is anymore. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19923
