Kenneth Graunke e95969cd95 i965/fs: Don't issue FB writes for bound but unwritten color targets.
We used to loop over all color attachments, and emit FB writes for each
one, even if the shader didn't write to a corresponding output variable.
Those color attachments would be filled with garbage (undefined values).

Football Manager binds a framebuffer with 4 color attachments, but draws
to it using a shader that only writes to gl_FragData[0..2].  This meant
that color attachment 3 would be filled with garbage, resulting in
rendering artifacts.  Now we skip writing to it, fixing rendering.

Writes to gl_FragColor initialize outputs[0..nr_color_regions-1] to
GRFs, while writes to gl_FragData[i] initialize outputs[i].

Thanks to Jason Ekstrand for tracking this down.

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

to build classic osmesa driver; 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.
