i965: Use unsynchronized maps for the program cache on LLC platforms.
There's no reason to stall on pwrite - the CPU always appends to the
buffer and never modifies existing contents, and the GPU never writes
it. Further, the CPU always appends new data before submitting a batch
that requires it.
This code predates the unsynchronized mapping feature, so we simply
didn't have the option when it was written.
Ideally, we would do this for non-LLC platforms too, but unsynchronized
mapping support only exists for LLC systems.

glsl: improve accuracy of atan()
Our current atan()-approximation is pretty inaccurate at 1.0, so
let's try to improve the situation by doing a direct approximation
without going through atan.
This new implementation uses an 11th degree polynomial to approximate
atan in the [-1..1] range, and the following identitiy to reduce the
entire range to [-1..1]:
atan(x) = 0.5 * pi * sign(x) - atan(1.0 / x)
This range-reduction idea is taken from the paper "Fast computation
of Arctangent Functions for Embedded Applications: A Comparative
Analysis" (Ukil et al. 2011).
The polynomial that approximates atan(x) is:
x * 0.
9999793128310355 - x^3 * 0.
3326756418091246 +
x^5 * 0.
1938924977115610 - x^7 * 0.
1173503194786851 +
x^9 * 0.
0536813784310406 - x^11 * 0.
0121323213173444
This polynomial was found with the following GNU Octave script:
x = linspace(0, 1);
y = atan(x);
n = [1, 3, 5, 7, 9, 11];
format long;
polyfitc(x, y, n)
The polyfitc function is not built-in, but too long to include here.

all cases. However, we really want to use write-back caching where
possible, as it is more efficient.
Most renderbuffers are not used for scanout - off-screen FBOs certainly
are fine, and non-pageflipped backbuffers should be fine as well. So
in most cases WB will work. However, we don't know what will be used
for scan-out, so we instead simply use the PTE value specified by the
kernel, as it knows these things.

colors, so this is still an improvement (and when we set up a linker for
TGSI, we'll hopefully fix those 8 fails).

glsl: Optimize min/max expression trees
Original patch by Petri Latvala <petri.latvala@intel.com>:
Add an optimization pass that drops min/max expression operands that
can be proven to not contribute to the final result. The algorithm is
similar to alpha-beta pruning on a minmax search, from the field of
AI.
This optimization pass can optimize min/max expressions where operands
are min/max expressions. Such code can appear in shaders by itself, or
as the result of clamp() or AMD_shader_trinary_minmax functions.
This optimization pass improves the generated code for piglit's
AMD_shader_trinary_minmax tests as follows:
total instructions in shared programs: 75 -> 67 (-10.67%)
instructions in affected programs: 60 -> 52 (-13.33%)
GAINED: 0
LOST: 0
All tests (max3, min3, mid3) improved.
A full shader-db run:
total instructions in shared programs:
4293603 ->
4293575 (-0.00%)
instructions in affected programs: 1188 -> 1160 (-2.36%)
GAINED: 0
LOST: 0
Improvements happen in Guacamelee and Serious Sam 3. One shader from
Dungeon Defenders is hurt by shader-db metrics (26 -> 28), because of
dropping of a (constant float (0.00000)) operand, which was
compiled to a saturate modifier.
Version 2 by Iago Toral Quiroga <itoral@igalia.com>:
Changes from review feedback:
- Squashed various cosmetic changes sent by Matt Turner.
- Make less_all_components return an enum rather than setting a class member.
(Suggested by Mat Turner). Also, renamed it to compare_components.
- Make less_all_components, smaller_constant and larger_constant static.
(Suggested by Mat Turner)
- Change mixmax_range to call its limits "low" and "high" instead of
"range[0]" and "range[1]". (Suggested by Connor Abbot).
- Use ir_builder swizzle helpers in swizzle_if_required(). (Suggested by
Connor Abbot).
- Make the logic more clearer by rearrenging the code and commenting.
(Suggested by Connor Abbot).
- Added comment to explain why we need to recurse twice. (Suggested by
Connor Abbot).
- If we cannot prune an expression, do not return early. Instead, attempt
to prune its children. (Suggested by Connor Abbot).
Other changes:
- Instead of having a global "valid" visitor member, let the various functions
that can determine this status return a boolean and check for its value
to decide what to do in each case. This is more flexible and allows to
recurse into children of parents that could not be prunned due to invalid
ranges (so related to the last bullet in the review feedback).
- Make sure we always check if a range is valid before working with it. Since
any use of get_range, combine_range or range_intersection can invalidate
a range we should check for this situation every time we use any of these
functions.
Version 3 by Iago Toral Quiroga <itoral@igalia.com>:
Changes from review feedback:
- Now we can make get_range, combine_range and range_intersection static too
(suggested by Connor Abbot).
- Do not return NULL when looking for the larger or greater constant into
mixed vector constants. Instead, produce a new constant by doing a
component-wise minmax. With this we can also remove of the validations when
we call into these functions (suggested by Connor Abbot).
- Add a comment explaining the meaning of the baserange argument in
prune_expression (suggested by Connor Abbot).
Other changes:
- Eliminate minmax expressions operating on constant vectors with mixed values
by resolving them.
No piglit regressions observed with Version 3.
