Summary: Currently the order of blocks returned by `IDF::calculate` can be non-deterministic. This was discovered in several attempts to enable SSAUpdaterBulk for JumpThreading (which led to miscompare in bootstrap between stage 3 and stage4). Originally, the blocks were put into a priority queue with a depth level as their key, and this patch adds a DFSIn number as a second key to specify a deterministic order across blocks from one level. The solution was suggested by Daniel Berlin. Reviewers: dberlin, davide Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D46646 llvm-svn: 332167 |
