Hi,  

I'm compiling a computationally-intensive program where performance is
an important issue.  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?
