It's much easier to do this in the generator rather than while coming out of NIR. brw_type_for_nir_type doesn't know the Gen, so we'd have to add a bunch of plumbing. The alternate fix is to not emit int64 moves for doubles in the first place... but that seems even more difficult. This change won't catch non-MOV instructions that try to use 64-bit integer types on Gen < 8. This may convert certain kinds of bugs in to different kinds of bugs that are more difficult to detect (since the assertions in the function won't catch them). NOTE: I don't think anything can emit mixed-type 64-bit moves until the same platform supports both ARB_gpu_shader_fp64 and ARB_gpu_shader_int64. When we enable int64 on Gen < 8, we can solve this problem other ways. This prevents regressions on HSW in the next patch.

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.
