[llvm-dev] Confused about optimization pass order

I'm wondering how exactly LLVM deals with passes that open up opportunities
for other passes. For example, InstCombine says that it opens many
opportunities for dead code/store elimination. However, the reverse may
also be true. How does LLVM currently handle this?
