Chris Lattner 714fa95d01 Fix PR4336: Iterating over use-def chains doesn't seem to be deterministic. ... 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! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73470 91177308-0d34-0410-b5e6-96231b3b80d8		2009-06-16 05:15:21 +00:00
