We need something that looks like a compiler and not like some hacker put some functions together. /rant This is a band-aid for these two problems: - The R600 and EG control-flow instructions appear in switch statements next to each other, causing conflicts when adding new instructions. - The ALU control-flow instructions are bitshifted by 3 (from CF_INST 26:29 to CF_INST 23:29, as is defined by r600 ISA) even for EG, where CF_INST is 22:29. To fix this mess, the 'inst' field is bitshifted to the left either by 22, 23, or 26 (directly in the definitions), such that it can be just or'd when making bytecode without any shifting. All switch statements have been divided into two, one for R600 and the other for EG. Of course, there is a better way to do this, but that is left for future work. Tested on RV730 and REDWOOD with no regressions. v2: minor cleanup as per Alex's comment. Reviewed-by: Alex Deucher <alexander.deucher@amd.com>
File: docs/README.WIN32 Last updated: 23 April 2011 Quick Start ----- ----- Windows drivers are build with SCons. Makefiles or Visual Studio projects are no longer shipped or supported. Run scons osmesa mesagdi to build classic mesa Windows GDI drivers; or scons libgl-gdi to build gallium based GDI driver. This will work both with MSVS or Mingw. Windows Drivers ------- ------- At this time, only the gallium GDI driver is known to work. Source code also exists in the tree for other drivers in src/mesa/drivers/windows, but the status of this code is unknown. General ------- After building, you can copy the above DLL files to a place in your PATH such as $SystemRoot/SYSTEM32. If you don't like putting things in a system directory, place them in the same directory as the executable(s). Be careful about accidentially overwriting files of the same name in the SYSTEM32 directory. The DLL files are built so that the external entry points use the stdcall calling convention. Static LIB files are not built. The LIB files that are built with are the linker import files associated with the DLL files. The si-glu sources are used to build the GLU libs. This was done mainly to get the better tessellator code. If you have a Windows-related build problem or question, please post to the mesa-dev or mesa-users list.
