Timothy Arceri 51daccb289 nir: add a loop unrolling pass
V2:
- tidy ups suggested by Connor.
- tidy up cloning logic and handle copy propagation
 based of suggestion by Connor.
- use nir_ssa_def_rewrite_uses to fix up lcssa phis
  suggested by Connor.
- add support for complex loop unrolling (two terminators)
- handle case were the ssa defs use outside the loop is already a phi
- support unrolling loops with multiple terminators when trip count
  is know for each terminator

V3:
- set correct num_components when creating phi in complex unroll
- rewrite update remap table based on Jasons suggestions.
- remove unrequired extract_loop_body() helper as suggested by Jason.
- simplify the lcssa phi fix up code for simple loops as per Jasons suggestions.
- use mem context to keep track of hash table memory as suggested by Jason.
- move is_{complex,simple}_loop helpers to the unroll code
- require nir_metadata_block_index
- partially rewrote complex unroll to be simpler and easier to follow.

V4:
- use rzalloc() when creating nir_phi_src but not setting pred right away
 fixes regression cause by ralloc() no longer zeroing memory.

V5:
- simplify calling of complex_unroll()
- use new loop terminator fields to get the break/continue from blocks
  and simplify loop unrolling code
- handle slightly less trivial loop terminators. if branches can
  now have instructions but can only contain a single block.
- use nir print type IR snippets in unroll function descriptions
- add better explanation and variable for why we need to clone
  additional times when the second terminator it the limiting
  terminator.
- partially convert out of ssa before unrolling loops (suggested by Jason)

v6:
- remove unused nir_builder
- use Jasons new from ssa helper
- tidy/fixup cursor use
- unroll terminators that contain control flow correctly
- unroll complex loops with control flow before the terminators
  correctly

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.
