Yeah, I was starting to get that impression too. I thought the old esp/ebp mixup was across all the gcc platforms - but who knows. Feel free to fix the RegisterContext_x86 enum definitions for esp/ebp - on Mac OS X we'll still be using the debugserver-provided register definitions. (and we don't use eh_frame very often on Mac OS X - we primarily use a local compact unwind format that I haven't written an importer for yet) Normally this kind of thing would be defined in the processor ABI document -- but I've never been able to find a document like that for IA-32. _______________________________________________ lldb-commits mailing list lldb-commits@cs.uiuc.edu http://lists.cs.uiuc.edu/mailman/listinfo/lldb-commits
