Before, when we encountered a situation where we had to optimistically color a node, we would immediately give up and push all the remaining nodes on the stack in the order of their index - which is a random, and potentially not optimal, order. Instead, choose one node to optimistically color in ra_select(), and then once we've optimistically colored it, keep on going as normal in the hopes that we've opened up more avenues for the normal select phase to make progress. In cases with high register pressure, this helps make the order we push things on the stack much better, and therefore increase the chance that we can allocate successfully. total instructions in shared programs: 4545447 -> 4545401 (-0.00%) instructions in affected programs: 1353 -> 1307 (-3.40%) GAINED: 124 LOST: 6 Signed-off-by: Connor Abbott <connor.abbott@intel.com> Reviewed-by: Eric Anholt <eric@anholt.net>
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.
