After trying multiple times to merge if-statements with phis
between them I've come to the conclusion that it cannot be done
without regressions. The problem is for some shaders we end up
with a whole bunch of phis for the merged ifs resulting in
increased register pressure.

So this patch just merges ifs that have no phis between them.
This seems to be consistent with what LLVM does so for radeonsi
we only see a change (although its a large change) in a single
shader.

as the only difference in the final code is the removal of the
redundent condition evaluations and jumps.

Also the biggest code reduction (~7%) for radeonsi was in a tomb
raider tressfx shader but for some reason this does not get merged
for i965.

5 years agocompiler/spirv: use 32-bit polynomial approximation for 16-bit asin()
Iago Toral Quiroga [Thu, 31 May 2018 08:34:03 +0000 (10:34 +0200)]
compiler/spirv: use 32-bit polynomial approximation for 16-bit asin()

The 16-bit polynomial execution doesn't meet Khronos precision requirements.
Also, the half-float denorm range starts at 2^(-14) and with asin taking input
values in the range [0, 1], polynomial approximations can lead to flushing
relatively easy.

An alternative is to use the atan2 formula to compute asin, which is the
reference taken by Khronos to determine precision requirements, but that
ends up generating too many additional instructions when compared to the
polynomial approximation. Specifically, for the Intel case, doing this
adds +41 instructions to the program for each asin/acos call, which looks
like an undesirable trade off.

So for now we take the easy way out and fallback to using the 32-bit
polynomial approximation, which is better (faster) than the 16-bit atan2
implementation and gives us better precision that matches Khronos
requirements.

nv30: avoid setting user_priv without setting cur_ctx

The whole user_priv thing is a mess, but as long as it's there, it
basically has to map 1:1 to the cur_ctx. Unfortunately we were setting
user_priv to some context, then that context could get deleted without
any draws/validations in it, leading user_priv to become NULL, with
cur_ctx still pointing at some old context. Then we wouldn't run the
switch logic, which in turn led to a NULL bufctx being dereferenced.

loader/dri3: Enable adaptive_sync via _VARIABLE_REFRESH property

The DDX driver can be notified of adaptive sync suitability by
flagging the application's window with the _VARIABLE_REFRESH property.

This property is set on the first swap the application performs
when adaptive_sync is set to true in the drirc.

It's performed here instead of when the loader is initialized for
two reasons:

(1) The window's drawable can be missing during loader init.
    This can be observed during the Unigine Superposition benchmark.

(2) Adaptive sync will only be enabled closer to when the application
    actually begins rendering.

If adaptive_sync is false then the _VARIABLE_REFRESH property
is deleted on loader init.

The property is only managed on the glx DRI3 backend for now. This
should cover most common applications and games on modern hardware.

Vulkan support can be implemented in a similar manner but would likely
require splitting the function out into a common helper function.
