Andres Gomez 1443c10d74 glsl: struct constructors/initializers only allow implicit conversions
When an argument for a structure constructor or initializer doesn't
match the expected type, only Section 4.1.10 “Implicit Conversions”
are allowed to try to match that expected type.

From page 32 (page 38 of the PDF) of the GLSL 1.20 spec:

  " The arguments to the constructor will be used to set the structure's
    fields, in order, using one argument per field. Each argument must
    be the same type as the field it sets, or be a type that can be
    converted to the field's type according to Section 4.1.10 “Implicit
    Conversions.”"

From page 35 (page 41 of the PDF) of the GLSL 4.20 spec:

  " In all cases, the innermost initializer (i.e., not a list of
    initializers enclosed in curly braces) applied to an object must
    have the same type as the object being initialized or be a type that
    can be converted to the object's type according to section 4.1.10
    "Implicit Conversions". In the latter case, an implicit conversion
    will be done on the initializer before the assignment is done."

v2: Remove also the now redundant constant conversion, the
    constant_record_constructor helper and the replacement code
    (Timothy).

Fixes GL44-CTS.shading_language_420pack.initializer_list_negative

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.
