| | | | | | | | | | | | It appears to have caught a use-after-free introduced as by r159567 and/or friends which call 'addPass' from many more places. The bug in 'addPass' doesn't appear to be new, and was spotted by inspection when ASan shown a bright light of a stacktrace at these functions.

* Extend TargetPassConfig to allow running only a subset of the normal passes.Bob Wilson2012-07-029-23/+118
| | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159570 91177308-0d34-0410-b5e6-96231b3b80d8
