I compiled under Redhat 6.0 pgcc patched egcs (with -06 and -mpentium). After compiling with it mbench (byte benchmark for linux), I noticed that my programs run only compiled with option -fforce_addr (I had to add "-mk6" also). Program mbench originally compiled by authors was quicker in integer parts, but have slower floating points parts than programs compiled with my new egcs (-mk6 -O6 -fforce_addr). How to understand this strange fact that old gcc with libc5 has better optimized integer parts. Maybe I need some special options? Write me about it.
