Iago Toral Quiroga bc73016703 i965/sbe: fix number of inputs for active components
In 16631ca30e we fixed gen9 active components to account for padded
inputs in the URB, which we can have with SSO programs. To do that,
instead of going through the bitfield of inputs (which doesn't include
padding information), we compute the number of inputs from the size
of the URB entry.

Unfortunately, there are some special inputs that are not stored in
the URB and that we also need to account for. These special inputs
are identified and handled during calculate_attr_overrides().

Instead of keeping track of the exact number of inputs, we just
program active components for all possible inputs like we do in
anvil.

This fixes a regression in a WebGL program that uses Point Sprite
functionality (specifically, VARYING_SLOT_PNTC).

v2:
 - Add 'Fixes' tag (Mark Janes)
 - make no_vue_inputs int instead of uint32_t, and add const qualifier
   to num_inputs variable (Ian)

v3:
 - Do not try to count inputs correctly, just program all input
   slots like we do in anvil (Ken)

Fixes: 16631ca30e (i965/sbe: fix active components for SSO programs with over 16 inputs)

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 https://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.
