Commit 259fc50545 added linker error for
mismatching uniform precision, as required by GLES 3.0 specification and
conformance test-suite.
Several Android applications, including Forge of Empires, have shaders
which violate this rule, on a dead varying that will be eliminated.
The problem affects a big number of applications using Cocos2D engine
and other GLES implementations accept this, this poses a serious
application compatibility issue.
Starting from GLSL ES 3.0, declarations with conflicting precision
qualifiers are explicitly prohibited. However GLSL ES 1.00 does not
clearly specify the behavior, except that
"Uniforms are defined to behave as if they are using the same storage in
the vertex and fragment processors and may be implemented this way.
If uniforms are used in both the vertex and fragment shaders, developers
should be warned if the precisions are different. Conversion of
precision should never be implicit."
The word "used" is not clear in this context and might refer to
1) declared (same as GLES 3.x)
2) referred after post-processing, or
3) linked after all optimizations are done.
Looking at existing applications, 2) or 3) seems to be widely adopted.
To avoid compatibility issues, turn the error into a warning if GLSL ES
version is lower than 3.0 and the data is dead in at least one of the
shaders.

Hilariously this is a fairly big win. Neil's multi-context-test
improves from ~24 to ~36 fps with llvmpipe on a Core i5-3317U. softpipe
also improves, from about 2.25 to 3.09 fps (when it's that slow, you're
allowed to be that precise).
I'd have added it to swrast classic, but the testcase wants GL 3.0 and
shaders, and that's not a thing classic has, so I figured making it work
on softpipe was crime enough.

Previously the CreateContext method of __DriverApiRec took a set of
arguments to describe the attribute values from the window system API's
CreateContextAttribs function. As more attributes get added this could
quickly get unworkable and every new attribute needs a modification for
every driver.
To fix that, pass the attribute values in a struct instead. The struct
has a bitmask to specify which members are used. The first three members
(two for the GL version and one for the flags) are always set. If the
bit is not set in the attribute mask then it can be assumed the
attribute has the default value. Drivers will error if unknown bits in
the mask are set.

It shouldn't be necessary to flush the context within the driver
implementation because the old context is explicitly flushed in
_mesa_make_current which is called a little further on. It is useful to
only have a single place that flushes when switching contexts to make it
easier to later implement the GL_KHR_context_flush_control extension.
The flush in intelMakeCurrent was added in commit 5505865 to implement
the GLX semantics that the context should be flushed when it is
released. When the commit was made there was no flush in
_mesa_make_current because it was only added later in 93102b4c. I think
that later commit effectively makes the first commit redundant.

Uploaded data must start at (stride * start), because we can't modify
start in all cases. If it's the first allocation, it's also the amount
of memory wasted. If the starting offset is larger than the size of
the upload buffer, the buffer is re-created, used for 1 upload, and then
thrown away. If the upload is small, most of the buffer space is unused
and wasted. Keep doing that and the OOM killer comes. It's actually
pretty quick.
With signed VB offsets, we can set min_out_offset = 0
in u_upload_alloc/u_upload_data.
This fixes OOM situations with SPECviewperf.

Replacing this with an array instead improves descriptor set

The dynamic index of a vector (not array!) is lowered to a sequence of
conditional assignments. However, the interpolate_at_* expressions
require that the interpolant is an l-value of a shader input.
So instead of doing conditional assignments of parts of the shader input
and then interpolating that (which is nonsensical), we interpolate the
entire shader input and then do conditional assignments of the interpolated
result.

The intended rule has been clarified in GLSL 4.60, Section 8.13.2
(Interpolation Functions):
"For all of the interpolation functions, interpolant must be an l-value
from an in declaration; this can include a variable, a block or
structure member, an array element, or some combination of these.
Component selection operators (e.g., .xy) may be used when specifying
interpolant."
For members of interface blocks, var->data.must_be_shader_input must be
determined on-the-fly after lowering interface blocks, since we don't want
to disable varying packing for an entire block just because one input in it
is used in interpolateAt*.
v2: keep setting must_be_shader_input in ast_function (Ian)
v3: follow the relaxed rule of GLSL 4.60
v4: only apply the relaxed rules to desktop GL
(the ES WG decided that the relaxed rules may apply in a future version
but not retroactively; see also
dEQP-GLES31.functional.shaders.multisample_interpolation.interpolate_at_centroid.negative.*)
