Hello, this is my first patch contributed to GHC. If there are any inadequacies about it (maybe like this introductory disclaimer), please let me know about it. So, the need for this patch arose, while I was involved with processing hcr files (external core output) and I noticed, that the output didn't fully conform to the specification [1]. No %local-tags were used, which turned out to be a real nuisance as it was not possible to determine which VDEFs can be erased in a further optimization process and which ones are exported by the module. Since the specification does not define the meaning of the %local-tag, I assume, it makes sense, that it tags all functions, that are not exported by the module. The patch does not fully comply to the specification, as in my implementation a local tag may appear before a VDEF but not before a VDEFG.
