llvm dev - Nov 2011 - [LLVMdev] Optimization passes

Is there a succinct way I can get the full list of which optimization passes are
applied, and in what order, for standard clang -O1, -O2, -O3?

$ clang -O3 -mllvm -debug-pass=Structure -x c - < /dev/null

lists the function passes, module passes and codegen passes that clang runs at
-O3.

Try adding the flags -mllvm --debug-pass=Structure when compiling a file 
with clang at the desired optimization level.

Yes, that's exactly the kind of thing I was hoping for, thanks so much.
