Thus far an Objective-C interface is a DW_TAG_structure_type that only has variables and properties as members. Objective-C methods are emitted as freestanding DW_TAG_subprogram function definitions. In addition, the .apple_objc accelerator table provides a mapping from ClassName -> [list of subprogram DIEs for each method in Class or one of its categories]. The idea behind this patch is to get rid of the accelerator table and encode the same information in the DIE hierarchy instead. LLDB was never using the accelerator table to accelerate lookup but only when it was in the middle of parsing a DW_TAG_structure_type of an Objective-C interface, so this shouldn't even come add a performance penalty. https://reviews.llvm.org/D48241 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
