Processors with out-of-order execution benefit *less* from scheduling
than non-OOO superscalar processors.

Not yet, but thank
Out of curiosity, were the benchmarks done with any of the Haifa
command-line-options, notably -fsched-interblock, -fsched-spec,
-fsched-spec-load, and -fbranch-count-reg ?
(toplev.c, grep for '#ifdef HAIFA', and read the comments
scattered elsewhere (haifa-sched.c))

I think the Haifa scheduler is only really effective on pure RISC p

This seems marginal, in other words. How did the res
Just curious what effect using the --enable-haifa flag for building
gcc-2.95.1/x86 would have so I did a comparison using the Dhrystone
benchmark from /usr/ports/benchmarks/bytebench.
This was run on a Ziatech 200Mhz Pentium cPCI system. I don't know
if this is really worth further testin
