Whoa! What are you doing with all of those flags?
I think you found a way to confuse gcc, resulting in the ICE.
Many of those flags are redundant at best.
-O3 should be about the same as -O2 plus a bunch of -f flags.
-march=i686 used to (and might still?) imply -mcpu=i686
I would try something simpler all the time. For example:
-O2 -Wall -Wno-unused -march=i686 -fomit-frame-pointer -pipe
or
-O3 -Wall -Wno-unused -march=i686 -fomit-frame-pointer -pipe
or
-O2 -Wall -Wno-unused -march=i686 -funroll-loops
-fstrength-reduce -fomit-frame-pointer -ffast-math
-fsigned-char -pipe
Although I *think* -fstrict-aliasing, -fstrength-reduce etc.
are implied by -O2 or -O3, some people claim differences if
they specify them anyway. (I've seen it before.)
Also I should note that aggressive settings can backfire on you
and actually miscompile! Such as the time I used -O3 on IRIX
and found the grid in tempest all screwed up. Also, -O3 isn't
always universally better. You might want to experiment with
the above settings and see which one gives you best results.
