Matt Turner e53130cc27 nir: Walk blocks in source code order in lower_vars_to_ssa.
Prior to this commit rename_variables_block() is recursively called,
performing a depth-first traversal of the control flow graph. The
function uses a non-trivial amount of stack space for local variables,
which puts us in danger of smashing the stack, given a sufficiently deep
dominance tree.

XCOM: Enemy Within contains a shader with such a dominance tree (1574
nir_blocks in total, depth of at least 143).

Jason tells me that he believes that any walk over the nir_blocks that
respects dominance is sufficient (a DFS might have been necessary prior
to the introduction of nir_phi_builder).

In fact, the introduction of nir_phi_builder made the problem worse:
rename_variables_block(), walks to the bottom of the dominance tree
before calling nir_phi_builder_value_get_block_def() which walks back to
the top of the dominance tree...

In any case, this patch ensures we avoid that problem as well.

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.
