- recent gdb handles DWARF fine (tested both with version 7.1.90.20100730 from mingw-w64 project, and 7.5-1 from mingw project) - http://people.freedesktop.org/~jrfonseca/bfdhelp/ was updated to handle DWARF - stabs requires ugly hacks to prevent compilation failures - mixing stabs/dwarf prevents proper backtraces (which is inevitable, given that the MinGW C runtime is pre-built with DWARF) For example, without this change I get: (gdb) bt #0 _wassert (_Message=0xf925060 L"Num < NumOperands && \"Invalid child # of SDNode!\"", _File=0xf60b488 L"llvm/include/llvm/CodeGen/SelectionDAGNodes.h", _Line=534) at ../../../../mingw-w64-crt/misc/wassert.c:51 #1 0x0368996b in _assert (_Message=0x39d7ee4 "Num < NumOperands && \"Invalid child # of SDNode!\"", _File=0x39d7e94 "llvm/include/llvm/CodeGen/SelectionDAGNodes.h", _Line=534) at ../../../../mingw-w64-crt/misc/wassert.c:44 #2 0x00000004 in ??
