issue in the way block variables are marked as parsed. In the DWARF parser we always parse all blocks for a function at once, so we can mark all blocks as having all variables parsed and avoid recursive function calls to try and reparse things that have already been handled. Fixed an issue with how variables get scoped into blocks. The DWARF parser can now handle abtract class definitions that contain concrete static variables. When the concrete instance of the class functions get instantiated, they will track down the concrete block for the abtract block and add the variable to each block. llvm-svn: 133302
