This is essentially the same problem fixed in an earlier patch for immediates. Setting the stride to zero will be particularly useful for my future SIMD lowering pass, because we will be able to just check whether the stride of a source register is zero and skip emitting the copies required to unzip it in that case. Instead of setting stride to zero in every caller of emit_uniformize() I've changed the function to return the result as its return value (previously it was being written into a caller-provided destination register), because this way we can enforce that the result is used with the correct regioning from the function itself. The changes to the prototype of its VEC4 counterpart are mainly for the sake of symmetry, VEC4 registers don't have stride. Reviewed-by: Samuel Iglesias Gonsálvez <siglesias@igalia.com> |

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.
