Geometry shader inputs are arrays, but they use an unusual array layout: instead of all array elements for a given geometry shader input being stored consecutively, all geometry shader inputs are interleaved into one giant array. As a result, the array stride we use to access geometry shader inputs must be equal to the size of the input VUE, rather than the size of the array element. This patch introduces a new virtual function, vec4_visitor::compute_array_stride(), which will allow geometry shader compilation to specialize the computation of array stride to account for the unusual layout of geometry shader input arrays. It also renames the local variable that the ir_dereference_array visitor uses to store the stride, to avoid confusion.

File: docs/README.WIN32 Last updated: 23 April 2011 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. 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.
