Previously we were relying on CFLAGS_FOR_BUILD to be the same as CFLAGS
when not cross compiling, but this assumption didn't take into
consideration 32-bit builds on 64-bit systems. More generally, not
honoring CFLAGS is bad.
Automake is evidently too stupid to accept

(cherry picked from commit 3310acdf47)
Since transform feedback needs to be able to access individual fields
of varying structs, we can no longer match up the arguments to
glTransformFeedbackVaryings() with variables in the vertex shader.
Instead, we build up a hashtable which records information about each
possible name that is a candidate for transform feedback, and then
match up the arguments to glTransformFeedbackVaryings() with the
contents of that hashtable.
Populating the hashtable uses the program_resource_visitor
infrastructure, so the logic is shared with how we handle uniforms.

Previously, transform feedback varyings were parsed in an ad-hoc
fashion that wasn't compatible with structs (or array of structs).
This patch makes it use parse_program_resource_name(), which correctly
handles both.
Note that parse_program_resource_name()'s technique for handling
mal-formed input strings is to simply let them through and rely on the
fact that a future name lookup will fail. Because of this,
tfeedback_decl::init() no longer needs to return a boolean error
code--it always succeeds, and if the input was mal-formed the error
will be detected later.

Currently, Blorp requires the source and destination formats to be
equal. However, we'd really like to be able to blit between XRGB and
ARGB formats; our BLT engine paths have supported this for a long time.
For ARGB -> XRGB, nothing needs to occur: the missing alpha is already
interpreted as 1.0. For XRGB -> ARGB, we need to smash the alpha
channel to 1.0 when writing the destination colors. This is fairly
straightforward with blending.
For now, this code is never used, as the source and destination formats
still must be equal. The next patch will relax that restriction.

(cherry picked from commit c0554141a9)
The BLT engine has many limitations. Currently, it can only blit
X-tiled buffers (since we don't have a kernel API to whack the BLT
tiling mode register), which means all depth/stencil operations get
punted to meta code, which can be very CPU-intensive.
Even if we used the BLT engine, it can't blit between buffers with
different tiling modes, such as an X-tiled non-MSAA ARGB8888 texture
and a Y-tiled CMS ARGB8888 renderbuffer. This is a fundamental
limitation, and the only way around that is to use BLORP.
Previously, BLORP only handled BlitFramebuffer. This patch adds an
additional frontend for doing CopyTexSubImage. It also makes it the
default. This is partly to increase testing and avoid hiding bugs,
and partly because the BLORP path can already handle more cases. With
trivial extensions, it should be able to handle everything the BLT can.
This helps PlaneShift massively, which tries to CopyTexSubImage2D
between depth buffers whenever a player casts a spell. Since these
are Y-tiled, we hit meta and software ReadPixels paths, eating 99% CPU
while delivering ~1 FPS. This is particularly bad in an MMO setting
because people cast spells all the time.
It also helps Xonotic in 4X MSAA mode. At default power management
settings, I measured a 6.35138% +/- 0.672548% performance boost (n=5).
(This data is from v1 of the patch.)

Ivybridge doesn't appear to have the same errata as Sandybridge; no
corruption was observed by setting it to more than the minimal correct
value. It's possible that we were simply lucky, since the URB entries
are 1024-bit on Ivybridge vs. 512-bit Sandybridge. Or perhaps the
underlying hardware issue is fixed.
Either way, we may as well program the minimum value since it's now
readily available, likely to be more efficient, and possibly more
correct.

(This commit message was primarily written by Paul Berry, who explained
what's going on far better than I would have.)
Previous to this patch, we thought that the only restrictions on
3DSTATE_SF's URB read length were (a) it needs to be large enough to
read all the VUE data that the SF needs, and (b) it can't be so large
that it tries to read VUE data that doesn't exist. Since the VUE map
already tells us how much VUE data exists, we didn't bother worrying
about restriction (a); we just did the easy thing and programmed the
read length to satisfy restriction (b).
However, we didn't notice this erratum in the hardware docs: "[errata]
Corruption/Hang possible if length programmed larger than recommended".
Judging by the context surrounding this erratum, it's pretty clear that
it means "URB read length must be exactly the size necessary to read all
the VUE data that the SF needs, and no larger". Which means that we
can't program the read length based on restriction (b)--we have to
program it based on restriction (a).
The URB read size needs to precisely match the amount of data that the
SF consumes; it doesn't work to simply base it on the size of the VUE.
Thankfully, the PRM contains the precise formula the hardware expects.

corruption in PlaneShift, and Piglit's fbo-5-varyings test.

In the documentation for BindBufferRange, OpenGL specs from 3.0
through 4.1 contain this language:
"The error INVALID_VALUE is generated if size is less than or
equal to zero or if offset + size is greater than the value of
BUFFER_SIZE."
This text was dropped from OpenGL 4.2, and it does not appear in the
GLES 3.0 spec.
Presumably the reason for the change is because come clients change
the size of the buffer after calling BindBufferRange. We don't want
to generate an error at the time of the BindBufferRange call just
because the old size of the buffer was too small, when the buffer is
about to be resized.
Since this is a deliberate relaxation of error conditions in order to
allow clients to work, it seems sensible to apply it to all versions
of GL, not just GL 4.2 and above.
(Note that there is no danger of this change allowing a client to
access data beyond the end of a buffer. We already have code to
ensure that that doesn't happen in the case where the client shrinks
the buffer after calling BindBufferRange).
