Why this code didn't work in all circumstances is unknown and without a
working Ironlake simulator (which uses a different AUB format) we'll
probably never know, short of a lot of experimentation, and spending a
bunch of time to try to optimize a few instructions on Ironlake is not
time well spent.
Moreover, for mix(vec4, vec4, vec4) using the accumulator introduces a
dependence between the otherwise independent per-component calculations.
Not using the accumulator, even if it means an extra instruction per
component might be preferable. We don't know, we don't have data, and
we don't have the necessary register on Ironlake for shader_time to tell
us.

(cherry picked from commit 200382be85)
The glGetGraphicsResetStatusARB from ARB_robustness extension always
returns GUILTY_CONTEXT_RESET_ARB and never returns NO_ERROR for guilty
context with LOSE_CONTEXT_ON_RESET_ARB strategy. This is because Mesa
returns GUILTY_CONTEXT_RESET_ARB if batch_active !=0 whereas kernel
driver never reset batch_active and this variable always > 0 for guilty
context. The same behaviour also can be observed for batch_pending and
INNOCENT_CONTEXT_RESET_ARB.
But ARB_robustness spec says:
If a reset status other than NO_ERROR is returned and subsequent calls
return NO_ERROR, the context reset was encountered and completed. If a
reset status is repeatedly returned, the context may be in the process
of resetting.
8. How should the application react to a reset context event?
RESOLVED: For this extension, the application is expected to query the
reset status until NO_ERROR is returned. If a reset is encountered, at
least one *RESET* status will be returned. Once NO_ERROR is
encountered, the application can safely destroy the old context and
create a new one.
The main problem is the context may be in the process of resetting and
in this case a reset status should be repeatedly returned. But looks
like the kernel driver returns nonzero active/pending only if the
context reset has already been encountered and completed. For this
reason the *RESET* status cannot be repeatedly returned and should be
returned only once.
The reset_count and brw->reset_count variables can be used to control
that glGetGraphicsResetStatusARB returns *RESET* status only once for
each context. Note the i915 triggers reset_count twice which allows to
return correct reset count immediately after active/pending have been
incremented.
v2 (idr): Trivial reformatting of comments.

_mesa_meta_setup_blit_shader() currently generates a fragment shader
which, irrespective of the number of draw buffers, writes the color
to only one 'out' variable. Current shader rely on an undefined
behavior and possibly works by chance.
From OpenGL 4.0 spec, page 256:
"If a fragment shader writes to gl_FragColor, DrawBuffers specifies a
set of draw buffers into which the single fragment color defined by
gl_FragColor is written. If a fragment shader writes to gl_FragData,
or a user-defined varying out variable, DrawBuffers specifies a set
of draw buffers into which each of the multiple output colors defined
by these variables are separately written. If a fragment shader writes
to none of gl_FragColor, gl_FragData, nor any user defined varying out
variables, the values of the fragment colors following shader execution
are undefined, and may differ for each fragment color."
OpenGL 4.4 spec, page 463, added an additional line in this section:
"If some, but not all user-defined output variables are written, the
values of fragment colors corresponding to unwritten variables are
similarly undefined."
V2: Write color output to gl_FragColor instead of writing to multiple
'out' variables. This'll avoid recompiling the shader every time
draw buffers count is updated.

Retrieving the high 32 bits of a signed multiply is rather annoying. It
appears that the simplest way to do this is to compute the absolute
value of the arguments, and perform a u32 x u32 -> u64 operation. If the
arguments' signs differ, then negate the result. Since there is no u64
support in the cvt instruction, we have the perform the 2's complement
negation "by hand".
This logic can come into use by the IMUL_HI instruction (very unlikely
to be seen), as well as from constant folding of division by a constant.

Separating the software fallbacks from the rest of the meta path (which
is usually hardware accelerated) gives callers better control over their
blitting options.
For example, i965 might want to try meta blit, hardware blits, then
swrast as a last resort. Splitting it makes that possible.
This updates all callers to maintain the existing behavior (even in the
few cases where it isn't desirable behavior - later patches can change
that).
