[PATCH] DebugInfo: Emit info for constant expressions in template arguments

[David Blaikie]

  Looks reasonable - did you test this end-to-end, just to be sure LLVM can cope with this? (I can't remember how specific I made the location handling logic in LLVM's codegen for non-type template parameters) Might be interesting to see what GCC does with it, just out of curiosity, and check the llvm-dwarfdump to see what it looks like (yeah, even though it's a Microsoft extension, etc - it'd be nice to not produce something that GCC finds particularly unpalatable)
