Interesting...
Since I was playing around with this already, I tried these options
with the Byte benchmark suite. Results for a K6-200 :
before-> after
Integer 3.451 -> 3.493
FP 1.747 -> 1.722
The full results are avaliable if you want them. Summary -- Most of
the integer results went up ~ 2 - 8 %, with Numeric Sorting dropping
by 10%. For floating point, LU Decomp went up 6%, Neural Net went down
13%, and Fourier was essentially unchanged.
According to the GCC man pages, -fforce-mem is turned on by -O2, and
benching seems to bear this out.
