Summary: The port is nearly straightforward. The only complication is related to the analyses handling, since one of the analyses used in this module pass is domtree, which is a function analysis. That requires asking for the results of each function and disallows a single interface for run-on-module pass action. Decided to copy-paste the main body of this pass. Most of its code is requesting analyses anyway, so not that much of a copy-paste. The rest of the code movement is to transform all the implementation helper functions like stripNonValidData into non-member statics. Extended all the related LLVM tests with new-pass-manager use. No failures. Reviewers: sanjoy, anna, reames Reviewed By: anna Subscribers: skatkov, llvm-commits Differential Revision: https://reviews.llvm.org/D41162 llvm-svn: 320796
