Hi,
I found out that when I use "-fno-unswitch-loops" option, it have no effect - loops are unswitched anyway:
-O3 -fno-unswitch-loops
Because of that to avoid -funswitch-loops optimization I must use something like this:
-O2 -finline-functions -fpredictive-commoning -fgcse-after-reload -ftree-vectorize
Is that a bug?
Tested with GCC 4.4.1 (m68k).
Regards
