but -falign-loops -freorder-blocks -ftree-vect-loop-version seem to be in.
Or all these vary by processor ?
I do not see align-loops set, and -freorder-blocks is definitely not
in. If -ftree-vect-loop-version is in, that would be a bug.
What target are you looking at, and what are you looking at that
suggests these options are enabled?
For example, using -fverbose-asm -S -Os (which here defaults to
-mtune=i486 -march=i486) on Linux x86, returns them, so I guess
they're in ?
This is GCC 4.4.4 from Slackware 13.1.
