I can't see the light with all these options, but a quick test with GCC 4.2.4
yields the same output with -O3 -ftree-loop-linear as with -O0. On
x86_64-linux
and x86_64-linux with -m32.
Turning random optimizations off is usually not a good idea, and the stated
options are surely not what you use - what is that instead?
