Aparently there are some issues in symbol resolution if an application
packages its own loader and you have a system-installed one. I don't
really understand the details, but it's not onorous to add.
The immediate write from PIPE_CONTROL is 64-bits at least on BDW. This
used to work on 64-bit archs because the compiler would align the following
anv_state struct up for us. However, in 32-bit builds, they overlap and it
causes problems.
We really need to stop pulling information directly out of shaders for
state setup. For one thing, if we want any sort of an on-disk shader
cache, having all of this metadata in one place is going to be crucial.
Also, passing it all through prog_data cleans up the compiler <-> state
setup API substantially.

It's extremely FS specific so the fact that we have a stage check in the
middle of it is rather bogus. While were here, we rename
setup_payload_gen4 and setup_payload_gen6 to make it obvious that they are
both FS specific.

Commit c98deb18d5 in 2010 disallowed embedded struct definitions
in ES. Then in 2013 d9bb8b7b56 disallowed it for everything but
GLSL 1.10.
Commit c98deb18d5 seemed the cleanest way to do the check so its
been extended to cover GL and the other version has been removed.

We no longer need to build any part of Mesa with Windows SDK 7.0.7600 or
MSVC 2008. MSVC 2013 will be the oldest we support.
In practice this means people are now free to declare variables in the
middle of blocks, on the whole Mesa tree.
Care should still be taken with variable length arrays and void pointer
arithmetic.

A few packets have dwords in them that are all MBZ and we failed to
write those. This change makes sure we iterate through all dwords and
write them all.
When NIR was originally drafted, there was no easy way to determine if
something was constant or not. The result was that we had lots of
special-casing for constant values such as this. Now that load_const
instructions are SSA-only, it's really easy to find constants and this
isn't really needed anymore.

This fixes two issues. First, we had a use-after-free in the case where
the instruction got deleted and we tried to return mov->dest.write_mask.
Second, in the case where we are doing a self-mov of a register, we delete
those channels that are moved to themselves from the write-mask. This
means that those channels aren't reported as being handled even though they
are. We now stash off the write-mask before remove unneeded channels so
that they still get reported as handled.

With the previous algorithm, when row and j are both 3, the index

This huge commit switches us over to using a simple xml format (genxml)
for defining our command streamer commands and a python script for
generating the pack headers we use in the driver.
This fixes an assertion failure in [at least] one of the Unreal Engine Linux
demo/games that uses DXT1 compression. Specifically, the "Vehicle Game".
At some point, the game ends up trying to blit mip level whose size is 2x2,
which is smaller than a DXT1 block. As a result, the assertion in the blit path
is triggered. It should be safe to simply make sure we align the width and
height, which is sadly an example of compression being less efficient.
NOTE: The demo seems to work fine without the assert, and therefore release
builds of mesa wouldn't stumble over this. Perhaps there is some unnoticeable
corruption, but I had trouble spotting it.
Thanks to Jason for looking at my backtrace and figuring out what was going on.

tl;dr: For many types of GL object, we can *NEVER* use the Gen function.
In OpenGL ES (all versions!) and OpenGL compatibility profile,
applications don't have to call Gen functions. The GL spec is very
clear about how you can mix-and-match generated names and non-generated
names: you can use any name you want for a particular object type until
you call the Gen function for that object type.
Here's the problem scenario:
- Application calls a meta function that generates a name. The first
Gen will probably return 1.
- Application decides to use the same name for an object of the same
type without calling Gen. Many demo programs use names 1, 2, 3,
etc. without calling Gen.
- Application calls the meta function again, and the meta function
replaces the data. The application's data is lost, and the app
fails. Have fun debugging that.
