While refactoring this code I was confused by both the name I had introduced (addNonArgumentVariable... but it has all this logic to handle argument numbering and keep things in order?) and by the redundancy. Seems when I fixed the misordered inlined argument handling, I didn't realize it was mostly redundant with the argument ordering code (which I may've also written, I'm not sure). So let's just rely on the more general case. The only oddity in output this produces is that it means when we emit all the variables for the current function, we don't track when we've finished the argument variables and are about to start the local variables and insert DW_AT_unspecified_parameters (for varargs functions) there. Instead it ends up after the local variables, scopes, etc. But this isn't invalid and doesn't cause DWARF consumers problems that I know of... so we'll just go with that because it makes the code nice & simple. (though, let's see what the buildbots have to say about this - *crosses fingers*) There will be some cleanup commits to follow to remove the now trivial wrappers, etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@220527 91177308-0d34-0410-b5e6-96231b3b80d8
