This will be used for GL_ARB_separate_shader_objects. That extension
not only allows separable shaders to rendezvous by location, but it also
allows traditionally linked shaders to rendezvous by location. The spec
says:
36. How does the behavior of input/output interface matching differ
between separable programs and non-separable programs?
RESOLVED: The rules for matching individual variables or block
members between stages are identical for separable and
non-separable programs, with one exception -- matching variables
of different type with the same location, as discussed in issue
34, applies only to separable programs.
However, the ability to enforce matching requirements differs
between program types. In non-separable programs, both sides of
an interface are contained in the same linked program. In this
case, if the linker detects a mismatch, it will generate a link
error.
v2: Make sure consumer_inputs_with_locations is initialized when
consumer is NULL. Noticed by Chia-I.
v3: Rebase on removal of ir_variable::user_location.
v4: Replace a (stale) FINISHME with some good explanation comments from
Eric.

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.
