I have AMD K6, so I use -mk6. I do have an option to use either -march=i486 ( default ) or -march=k6. With latter, I get slightly worse performance benchmarks. So I was wondering, is K6 optimization going to be improved before the next release? I obviously expect -march=k6 to produce better benchmarks. Thanks Igor P.S. If I don't specify -mk6, gcc segfaults. So while that's not a work-stopper for me now, you might want to take a look at it. What is the default cpu target?
