This makes the whole LOAD_PAYLOAD munging unnecessary which simplifies the code and will allow the optimization to succeed in more cases independent of whether the LOAD_PAYLOAD instruction can be found or not. The following patch is squashed in: SQUASH: i965/fs: Add basic dataflow check to opt_sampler_eot(). The sampler EOT optimization pass naively assumes that the texturing instruction provides all the data used by the FB write just because they're standing next to each other. The least we should be checking is whether the source and destination regions of the FB write and texturing instructions match. Without this the previous seemingly harmless patch would have caused opt_sampler_eot() to misoptimize a shader from dota-2 causing DCE to eliminate all of its 78 instructions except for the final sampler EOT message (!).

File: docs/README.WIN32 Last updated: 21 June 2013 Quick Start ----- ----- Windows drivers are build with SCons. Makefiles or Visual Studio projects are no longer shipped or supported. Run 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. Recipe ------ Building on windows requires several open-source packages. These are steps that work as of this writing. - install python 2.7 - install scons (latest) - install mingw, flex, and bison - install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs get pywin32-218.4.win-amd64-py2.7.exe - install git - download mesa from git see http://www.mesa3d.org/repository.html - run scons 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.
