From page 46 (page 52 of the PDF) of the GLSL 4.20 spec:
" More than one layout qualifier may appear in a single
declaration. If the same layout-qualifier-name occurs in multiple
layout qualifiers for the same declaration, the last one overrides
the former ones."
Consider this example:
" #version 150
#extension GL_ARB_shading_language_420pack: enable
layout(max_vertices=2) layout(max_vertices=3) out;
layout(max_vertices=3) out;"
Although different values for "max_vertices" results in a compilation
error. The above code is valid because max_vertices=2 is ignored.
Hence, when merging qualifiers in an ast_type_qualifier, we now ignore
new appearances of a same layout-qualifier-name if the new
"is_multiple_layouts_merge" parameter is on, since the GLSL parser
works in this case from right to left.
In addition, any special treatment for the buffer, uniform, in or out
layout defaults has been moved in the GLSL parser to the rule
triggered just after any previous processing/merging on the
layout-qualifiers has happened in a single declaration since it was
run too soon previously.
Fixes GL44-CTS.shading_language_420pack.qualifier_override_layout

docs/README.WIN32
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.
