The saturate propagation pass recognizes that the second instruction below does not interfere with an attempt to propagate the saturate modifier from instruction 3 to 1. 1: add(8) dst0 src0 src1 2: mov.sat(8) dst1 dst0 3: mov.sat(8) dst2 dst0 Unfortunately, we did not consider the case of instruction 2 having a source modifier on dst0. Take for instance: 1: add(8) dst0 src0 src1 2: mov.sat(8) dst1 -dst0 3: mov.sat(8) dst2 dst0 Consider such an instruction to interfere. Increase instruction counts in Anomaly 2, which could be a bug fix depending on the values the first instruction produces. instructions in affected programs: 53228 -> 53934 (1.33%) HURT: 360 Cc: <mesa-stable@lists.freedesktop.org> Reviewed-by: Ian Romanick <ian.d.romanick@intel.com>
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. - 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.
