I have a couple of more questions.

1. Does -std-compile-opts of opt do the same optimization with llvm-gcc
with -O[1-3] options? If I want to debug into passes through llvm-gcc,
how do I set a breakpoint right before pass execution? In my gdb
llvm-gcc session, I don't have llvm::PassManager available.

2. When I use "-p" with opt, there is nothing I can see from the
output. Instead, "--debug-pass=Details" gives me more detailed info. Did
I miss other stuffs that are required to be with "-p?"
