Can someone point me at a document that shows which optimizations are
turned on by -O and -O2 in djgpp? I have "Using GNU CC" but the actual
optimzations that are done by a particular version of gcc may be
different from those listed in the manual.
I have a program that I've ported from a sparc/unix environment that
works perfectly until I turn on -O or -O2 optimization, and then it
segvs immediately, and I'm trying to track down which optimizations
are conflicting with the original authors ideas of what is safe coding
:-)
