This cleans up fs_inst::regs_read() slightly by disentangling the calculation of "components" from the handling of message payload arguments. This will also simplify the SIMD lowering and logical send message lowering passes, because it will avoid expressions like 'regs_read * REG_SIZE / component_size' which are not only ugly, they may be inaccurate because regs_read rounds up the result to the closest register multiple so they could give incorrect results when the component size is lower than one register (e.g. uniforms). This didn't seem to be a problem right now because all such expressions happen to be dealing with per-channel GRFs only currently, but that's by no means obvious so better be safe than sorry. v2: Split PIXEL_X/Y and LINTERP into separate case blocks.

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.
