hi, i'm using gcc2.6.0 on a Pentium 90 running Solaris2.5. i have a large application which is floating point intensive. prelimanry benchmarks show the float performance to only be about half of what our 50mhz sparc20s give, whereas the published specflops say the pentiums should only be 5-10% slower. i remember hearing a while back that originally gcc didn't do a good job of optimization on the pentiums, but that someone had fixed that. is the solution to compile the latest version of gcc? or do i have to use some specific compiler flags to improve performance? i looked for a gcc faq but didn't see one, so i'd appreciate it if someone could point me to a source of information. thanks, -ed
