Duncan P. N. Exon Smith aa712f8848 ValueMapper: Avoid recursion in mapSimplifiedMetadata, NFC ... The main change is to delay materializing GlobalValue initializers from Mapper::mapValue until Mapper::~Mapper. This effectively removes all recursion from mapSimplifiedMetadata, as promised in r265270. mapSimplifiedMetadata calls mapValue for ConstantAsMetadata nodes to find the mapped constant, and now it shouldn't be possible for mapValue to indirectly re-invoke mapMetadata. I'll add an assertion to that effect in a follow-up (separated so that the assertion can easily be reverted independently, if it comes to that). This a step toward a broader goal: converting Mapper::mapMetadataImpl from a recursive to an iterative algorithm. When a BlockAddress points at a BasicBlock inside an unmaterialized function body, we need to delay it until the function body is materialized in Mapper::~Mapper. This commit creates a temporary BasicBlock and returns a new BlockAddress, then RAUWs the BasicBlock once it is known. This situation should be extremely rare since a BlockAddress is usually used from within the function it's referencing (and BlockAddress itself is rare). There should be no observable functionality change. llvm-svn: 265273		2016-04-03 20:17:45 +00:00
