Previously, remove_dead_constants() would renumber the UNIFORM registers to be sequential starting from zero, and the resulting register number would be used directly as an index into the params[] array. This renumbering made it difficult to collect and save information about pull constant locations, since setup_pull_constants() and move_uniform_array_access_to_pull_constants() used different names. This patch generalizes setup_pull_constants() to decide whether each uniform register should be a pull constant, push constant, or neither (because it's unused). Then, it stores mappings from UNIFORM register numbers to params[] or pull_params[] indices in the push_constant_loc and pull_constant_loc arrays. (We already did this for pull constants.) Then, assign_curb_setup() just needs to consult the push_constant_loc array to get the real index into the params[] array. This effectively folds all the remove_dead_constants() functionality into assign_constant_locations(), while being less irritable to work with. v2: Add assert(remapped <= i), requested by Topi.

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 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. Recipe ------ Building on windows requires several open-source packages. These are steps that work as of this writing. 1) install python 2.7 2) install scons (latest) 3) install mingw, flex, and bison 4) install libxml2 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs get libxml2-python-2.9.1.win-amd64-py2.7.exe 5) install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs get pywin32-218.4.win-amd64-py2.7.exe 6) install git 7) download mesa from git see http://www.mesa3d.org/repository.html 8) 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.
