2013-05-21scons: Don't force stabs debug format for Mingw.José Fonseca1-42/+0
- 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 ??

2011-09-12scons: Don't use gstabs on mingw-64.José Fonseca1-3/+5
2011-09-06scons: Move MinGW flags from crossmingw.py to gallium.pyJosé Fonseca1-8/+0
So that they are used by native MinGW compilers too.
2011-08-30scons: Prefer x86_64-w64-mingw32- prefix.José Fonseca1-1/+1
This allows to use mingw-w64 binaries on debian systems which already include a (typically incomplete) 64 cross compiler.
2011-08-26scons: don't compile some files with -gstabs if using mingw32Brian Paul1-0/+38
Compiling some (large) files with i686-pc-mingw32-gcc 4.2.2 (at least) and the -gstabs option triggers a compiler error. Use this work-around to simply compile the effected files without -gstabs.
2011-02-03scons: Eliminate libgcc_s_sjlj-1.dll dependencyJosé Fonseca1-0/+3
Certain mingw32 cross compilers (e.g. RedHat's) defaults to use DLL gcc runtime. Given the main deliverable from this project are self-contained drivers, which are loaded by any application, this dependency can cause havoc.
2010-09-27scons: Add MinGW-w64 prefixes for MinGW build.Vinson Lee1-0/+2
2010-05-05scons: Add support for Mingw64.José Fonseca1-1/+10
2010-04-09scons: Set -gstabs for C++ too.José Fonseca1-1/+1
2010-02-10scons: add another prefix for mingw32 on FedoraBrian Paul1-0/+1
(cherry picked from commit f1afb352daf0e74751c99254592eef863c64392a)
2010-02-04scons: Have MinGW target MSVCRT 7.0José Fonseca1-0/+1
Necessary for _aligned_malloc/free().
2009-09-24scons: Don't require -liberty on MinGW.José Fonseca1-1/+1
Not always present.
2009-06-19scons: Output the friendly "Linking ..." message when creating DLLs with MinGW.José Fonseca1-1/+1
2009-01-26scons: Request the stabs debug info format for Mingw.José Fonseca1-0/+4
Mingw gdb apparently chokes on dwarf debug info.
2009-01-24scons: Use --enable-stdcall-fixup only when building DLLs.José Fonseca1-1/+2
2009-01-14scons: Use .a suffix for MinGW.José Fonseca1-6/+4
This allows to build MinGW and MSVC within the same dir.
2008-11-18scons: Support MinGW32 cross compiler.José Fonseca1-0/+182
To build an alternative opengl32.dll with Gallium's software-rasterizer from a debian-based distribution run: sudo apt-get install mingw32 scons platform=windows toolchain=crossmingw machine=x86 winsys=gdi dri=no
