Treating everything as scalar arrays allows us to drop a bunch of special case input/output munging all throughout the backend. Instead, we just need to remap the TessLevel components to the appropriate patch URB header locations in remap_patch_urb_offsets(). We also switch to treating the TES input versions of these as ordinary shader inputs rather than system values, as remap_patch_urb_offsets() just makes everything work out without special handling. This regresses one Piglit test: arb_tessellation_shader-large-uniforms/GL_TESS_CONTROL_SHADER-array-at-limit The compiler starts promoting the constant arrays assigned to gl_TessLevel* to uniform arrays. Since the shader also has a uniform array that uses the maximum number of uniform components, this puts it over the uniform component limit enforced by the linker. This is arguably a bug in the constant array promotion code (it should avoid pushing us over limits), but is unlikely to penalize any real application.

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.
