Duncan P. N. Exon Smith a77d073305 ValueMapper: Stop memoizing ConstantAsMetadata ... Stop memoizing ConstantAsMetadata in ValueMapper::mapMetadata. Now we have to recompute it, but these metadata aren't particularly common, and it restricts the lifetime of the Metadata map unnecessarily. (The motivation is that I have a patch which uses a single Metadata map for the lifetime of IRMover. Mehdi profiled r266446 with the patch applied and we saw a pretty big speedup in lib/Linker.) llvm-svn: 266513		2016-04-16 03:39:44 +00:00
