Bob Wilson a848f156de Extend TargetPassConfig to allow running only a subset of the normal passes. ... This is still a work in progress but I believe it is currently good enough to fix PR13122 "Need unit test driver for codegen IR passes". For example, you can run llc with -stop-after=loop-reduce to have it dump out the IR after running LSR. Serializing machine-level IR is not yet supported but we have some patches in progress for that. The plan is to serialize the IR to a YAML file, containing separate sections for the LLVM IR, machine-level IR, and whatever other info is needed. Chad suggested that we stash the stop-after pass in the YAML file and use that instead of the start-after option to figure out where to restart the compilation. I think that's a great idea, but since it's not implemented yet I put the -start-after option into this patch for testing purposes. llvm-svn: 159570		2012-07-02 19:48:45 +00:00
