Subject: GCC x86 optimizations


I've been using djgpp since 1.07 with gcc 2.2.2. Every release of
gcc since has produced slower code, by about 10-15 % for my particular
application. So I've kept using dj 1.08 and gcc 2.2.2. When I heard about
the intel optimized gcc, I grabed it and compiled it. It runs fine and
compiles properly. However, the (produced) code is still slower than 2.2.2 :-<
anyway, I thought I'd let people know so they don't spend hours compiling
the intel version.
FYI, I have a 486DX33 with 256k of cache, 16 MB of memory.
I cannot comment on the speed of the code on a pentium.
(I'm not sure I still have the intel version sitting around somewhere,
but cc1 is huge [several megs]. If I still have it, I could make it
available...)

Hope this helps.
