Does anybody know about an optimization test or benchmark available?
It happens sometimes to me that the codes with and without optimization
give different results. E.g. compiling paranoia.c from netlib on my
linux box with gcc 2.7.2.3.f.1 with optimizations enabled (-O or -O2)
produces an infinite loop and reports completely misleading results. The
same compiler on sgi (mips 2) works O.K.
Can you give URL to the page devoted to the computer optimization? Is
there any list (or standard) of situations whose the optimizer should
optimize or leave intact?


Thanks, Cyril
