The Gen5+ sampler message payload construction code steps through the
coordinate and derivative components by induction like 'coordinate =
offset(coordinate, bld, 1)', the problem is that while doing that it
may step one past the end of the coordinate vector causing an
assertion failure in offset() if it happens to be a (single component)
immediate. Right now coordinates and derivatives are typically passed
as actual registers but that will no longer be the case when we start
propagating constants into logical messages.
Instead express coordinate components in closed form like
'offset(coordinate, bld, i)' -- The end result seems slightly more
readable that way and it allows passing the coordinate and derivative
registers by const reference instead of by value, so it seems like a
clean-up in its own right.
v2: Fold a few post-increment operators into the last MOV
statement. (Jason)

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.
