Duncan P. N. Exon Smith eeb2c7e32c ValueMapper: Add support for seeding metadata with nullptr ... Support seeding a ValueMap with nullptr for Metadata entries, a situation I didn't consider in the Metadata/Value split. I added a ValueMapper::getMappedMD accessor that returns an Optional<Metadata*> with the mapped (possibly null) metadata. IRMover needs to use this to avoid modifying the map when it's checking for unneeded subprograms. I updated a call from bugpoint since I find the new code clearer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@265228 91177308-0d34-0410-b5e6-96231b3b80d8		2016-04-02 17:04:38 +00:00
