glsl: tidy up IR after loop unrolling

c7affbf6875622a enabled GLSLOptimizeConservatively on some
drivers. The idea was to speed up compile times by running
the GLSL IR passes only once each time do_common_optimization()
is called. However loop unrolling can create a big mess and
with large loops can actually case compile times to increase
significantly due to a bunch of redundant if statements being
propagated to other IRs.

Here we make sure to clean things up before moving on.

There was no measureable difference in shader-db compile times,
but it makes compile times of some piglit tests go from a couple
of seconds to basically instant.

The shader-db results seemed positive also:

Timothy Arceri [Mon, 4 Sep 2017 03:11:49 +0000 (13:11 +1000)]
glsl: make loop unrolling more like the nir unrolling path

The old code assumed that loop terminators will always be at
the start of the loop, resulting in otherwise unrollable
loops not being unrolled at all. For example the current
code would unroll:

  int j = 0;
  do {
     if (j > 5)
        break;

     ... do stuff ...

     j++;
  } while (j < 4);

But would fail to unroll the following as no iteration limit was
calculated because it failed to find the terminator:

  int j = 0;
  do {
     ... do stuff ...

     j++;
  } while (j < 4);

Also we would fail to unroll the following as we ended up
calculating the iteration limit as 6 rather than 4. The unroll
code then assumed we had 3 terminators rather the 2 as it
wasn't able to determine that "if (j > 5)" was redundant.

  int j = 0;
  do {
     if (j > 5)
        break;

     ... do stuff ...

     if (bool(i))
        break;

     j++;
  } while (j < 4);

This patch changes this pass to be more like the NIR unrolling pass.
With this change we handle loop terminators correctly and also
handle cases where the terminators have instructions in their
branches other than a break.

V2:
- fixed regression where loops with a break in else were never
  unrolled in v1.
- fixed confusing/wrong naming of bools in complex unrolling.

7 years agoanv/wsi: Allocate enough memory for the entire image

anv/wsi: Allocate enough memory for the entire image

Previously, we allocated memory for image->plane[0].surface.isl.size
which is great if there is no compression.  However, on BDW, we can do
CCS_D on X-tiled images so we also have to allocate space for the
auxiliary buffer.  This fixes hangs in some of the WSI CTS tests and
should also reduce hangs in real applications.  In particular, it fixes
the dEQP-VK.wsi.*.incremental_present.* test group.

When we hand the image off to X11 or Wayland, it will ignore the CCS
entirely which is ok because we do a resolve when it's transitioned to
VK_IMAGE_LAYOUT_PRESENT_SRC_KHR.

When a texture is immutable, we can't tack on extra levels

level limit and return an error if it's surpassed.
