We will need this later on when we implement proper support for
precision qualifiers in the drivers and also to do link time checks for
uniforms as indicated by the spec.
This patch also adds compile-time checks for variables without precision
information (currently, Mesa only checks that a default precision is set
for floats in fragment shaders).
As indicated by Ian, the addition of the precision information to
ir_variable has been done using a bitfield and pahole to identify an
available hole so that memory requirements for ir_variable stay the
same.
v2 (Ian):
- Avoid if-ladders by defining arrays of supported sampler names and
indexing
into them with type->sampler_array + 2 * type->sampler_shadow
- Make the code that selects the precision qualifier to use an utility
function
- Fix a typo
v3 (Tapani):
- rebased
- squashed in "Precision qualifiers are not allowed on structs"
- fixed select_gles_precision for sampler arrays
- fixed precision_qualifier_allowed for arrays of structs
v4 (Tapani):
- add atomic_uint handling
- do not allow precision qualifier on images
(issues reported by Marta)
v5 (Tapani):
- support precision qualifier on image types
v6 (Tapani):
- set precision qualifier on interface block members

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.
