The problem was that BitcodeReader::materializeModule would read functions from the bc file in densemap pointer key order (doubly non-deterministic!), which would cause the use-def chains to be set up for globals in non-determinstic order. Non-determinstic use/def chains can cause nondeterminism in many places down-stream. Many thanks to Julien Lerouge for putting together the pass in the PR that shows the issue! llvm-svn: 73470 |
