Previously, the memory context situation was a bit of a mess: fs_visitor allocated its own memory context, and freed it in the destructor. However, some data produced by fs_visitor (such as the list of instructions) needs to live beyond when fs_visitor is "done", so the caller can pass it to fs_generator. Everything worked out because brw_wm_fs_emit's fs_visitor variables happen to not go out of scope until the end of the function. But that meant that moving the declaration of, say, the SIMD16 fs_visitor instance, could cause everything to explode. Using a memory context that exists for the duration of the compile is clearer, and should be equivalent. Ultimately, we don't want to use 'c', but this matches the behavior of fs_generator and gen8_fs_generator, so it'll be simple to change later.

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.
