Matt Turner 099cbc1477 i965/fs: Track dependencies in instruction scheduling per reg offset.
Previously instruction scheduling tracked dependencies on a per-register
basis. This meant that there was an artificial dependency between
interpolation instructions writing into the same virtual register.

Instruction scheduling would insert a number of instructions between the
two instructions in this example, when they are actually independent.

   linterp vgrf8+0.0:F, hw_reg2:F, hw_reg3:F, hw_reg6:F
   linterp vgrf8+1.0:F, hw_reg2:F, hw_reg3:F, hw_reg6+16:F

This lead to cases where the first texture coordinate is interpolated at
the beginning of the shader, but the second is done immediately before
the texture operation that uses it as a source.

After this change, the artificial dependency is removed and the
interpolation instructions are scheduled together.

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.
