This was ridiculous. We were ignoring the inst->header.saturate flag in the case of math and only math. On gen4, we would leave inst->header.saturate in place if it happened to be set, which would end up being applied to the implicit mov and thus trash the first argument. On gen6, we would overwrite inst->header.saturate with the saturate flag from the argument, which was not set appropriately in brw_vec4_emit.cpp, and was only not a bug due to our incompetence at coalescing saturate moves. By ripping the argument out and making saturate work just like all the other brw_eu_emit.c code generation, we can avoid both these classes of bugs. Fixes piglit fog-modes, and the new specific fs-saturate-exp2 case. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=48628 NOTE: This is a candidate for the 8.0 branch.

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.
