scons: Don't force stabs debug format for Mingw.
- 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 ?? () #3 0x00000004 in ?? () #4 0x0f60b488 in ?? () #5 0x00000000 in ?? () While with this change I get: (gdb) bt #0 _wassert (_Message=0xfb982e8 L"Num < NumOperands && \"Invalid child # of SDNode!\"", _File=0xefbcb40 L"llvm/include/llvm/CodeGen/SelectionDAGNodes.h", _Line=534) at ../../../../mingw-w64-crt/misc/wassert.c:51 #1 0x039c996b in _assert (_Message=0x3d17f24 "Num < NumOperands && \"Invalid child # of SDNode!\"", _File=0x3d17ed4 "llvm/include/llvm/CodeGen/SelectionDAGNodes.h", _Line=534) at ../../../../mingw-w64-crt/misc/wassert.c:44 #2 0x033111cc in getOperand (Num=4, this=<optimized out>) at llvm/include/llvm/CodeGen/SelectionDAGNodes.h:534 #3 getOperand (i=4, this=<optimized out>) at llvm/include/llvm/CodeGen/SelectionDAGNodes.h:779 #4 llvm::SelectionDAG::getNode (this=0xf00cb08, Opcode=79, DL=..., VT=..., N1=..., N2=...) at llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cpp:2859 #5 0x03377b20 in llvm::SelectionDAGBuilder::visitExtractElement (this=0xfb45028, I=...) at llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp:2803 [...] Reviewed-by: Brian Paul <brianp@vmware.com>
