OPT optimizations


OPT documentation mentions optimization options -O1,-O2 and -O3 etc.
(I am using -O0, no optimizations). The documentation does not tell
you what optimizations are included in each option. It says they are
same as gcc. gcc dodoc is not of much help either. Where can I find
this information.

Just call

opt -O3 -debug-pass=Arguments program.ll

which prints the list of passes executed.
