I need to be able to determine exactly which optimizations will happen when
different -O# options are used. The docs seem to tell which ones are turned
on usually, but I need to be able to figure out precisely which ones are
turned on for my target for each optimization level. This info must be
somewhere in the gcc source, but I haven't been able to figure out where yet
(awful lot of source to go at this blind...). Could someone point me in the
right direction?
BTW--if it matters my target is m68k-coff
Thanks,
- Steve
