[PATCH] D43002: Emit S_OBJNAME symbol in CodeView

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

Thinking about it again, maybe it should be an MCOption like David suggested. S_OBJNAME should probably refer to the final location of the native object file, which is only known to whoever sets up MCOptions. For example, with "fat" LTO, the linker is the one responsible for setting up the output file.

Named metadata nodes are things like `!llvm.ident = {...}` that you see at global scope in .ll files, but I don't think it's relevant.

As far as this patch is concerned, I don't think we should put this thing on the compile unit. The whole idea of compile units is to preserve the separation between compilation units through LTO, but we can't really do that in codeview anyway.
