wich gcc-4.0-20050102 i've some unexpected failure.
i've played something with this test and i've found that they don't work
at -O2 cause -funit-at-a-time.
a little scheme
-O1 -funit-at-a-time x
-O0 -funit-at-a-time v
So it's like some optimitation in O1 can to eccessive work with
-funit-at-a-time, well the bad thing is that
O0 -fcprop-registers -fdefer-pop -fguess-branch-probability
-fif-conversion -fif-conversion2 -floop-optimize -fmerge-constants
-fthread-jumps -fmerge-constants -fdelayed-branch -fthread-jumps
-funit-at-a-time -fexceptions -fnon-call-exception
...Using all -O1 flag in documentation work.
something is wrong... perhaps in me ;-)
But how can I implement unimaginable chaos in my compiler?
