This patch introduces a new function, vec4_visitor::emit_vertex(), which contains the code for emitting vertices that will need to be common between the vertex and geometry shaders. Geometry shaders will need to use a different message header, and a different opcode, for their URB writes, so we introduce virtual functions emit_urb_write_header() and emit_urb_write_opcode() to take care of the GS-specific behaviours. Also, since vertex emission happens at the end of the VS, but in the middle of the GS, we need to be sure to only call emit_shader_time_end() during VS vertex emission. We accomplish this by moving the call to emit_shader_time_end() into the VS implementation of emit_urb_write_opcode().

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.
