This covers the pattern where a KILL_IF is used, which triggers a comparison of -x to 0. This can usually be folded into the comparison whose result is being compared to 0, however it may, itself, have already been combined with another comparison. That shouldn't impact the logic of this pass however. With this and the & 1.0 change, code like 00000020: 001c0001 80081df4 set b32 $r0 lt f32 $r0 0x3e800000 00000028: 001c0000 201fc000 and b32 $r0 $r0 0x3f800000 00000030: 7f9c001e dd885c00 set $p0 0x1 lt f32 neg $r0 0x0 00000038: 0000003c 19800000 $p0 discard becomes 00000020: 001c001d b5881df4 set $p0 0x1 lt f32 $r0 0x3e800000 00000028: 0000003c 19800000 $p0 discard Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> |

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 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.
