This does the inverse operation of shuffle_32bit_load_result_to_64bit_data and we will use it when we need to write 64-bit data in the layout expected by untyped write messages. v2 (curro): - Use subscript() instead of stride() - Assert on the input types rather than silently retyping. - Use offset() instead of horiz_offset(), drop the multiplier definition. - Drop the temporary vgrf and force_writemask_all. - Make component_i const. - Move to brw_fs_nir.cpp v3 (curro): - Pass dst and src by reference. - Simplify allocation of tmp register. - Move to brw_fs_nir.cpp. - Get rid of the temporary. v3 (Iago): - Check that the src and dst regions do not overlap, since that would typically be a bug in the caller.

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.
