glsl: skip comparison opt when adding vars of different size

The spec allows adding scalars with a vector or matrix. In this case
the opt was losing swizzle and size information.

  a good way to keep some of that property."

This patch differs from the one proposed by Dave in that it only adds
the NF_DONT_MOVE flag to copy_move instructions that are created by split_phi*
and that are located in loops.

Fixes piglit: tests/shaders/ssa/fs-while-loop-rotate-value.shader_test
(no regressions in the shader set). It also fixes all failing tests from

  dEQP-GLES3.functional.shaders.loops.*

freedreno: fix HW_ATOMIC_COUNTERS cap

This was mistakenly exposed, even though we want atomic counters to be
lowered to atomic ops on an SSBO like nearly every other GPU.  Which
somehow recently started getting segfaults due to calling a null
pipe->set_hw_atomic_buffers().

Fixes a crash in stk, and probably other things.

6 years agoradv: add VK_EXT_display_control to radv driver [v5]

radv: add VK_EXT_display_control to radv driver [v5]

This extension provides fences and frame count information to direct
display contexts. It uses new kernel ioctls to provide 64-bits of
vblank sequence and nanosecond resolution.

v2:
Rework fence integration into the driver so that waiting for
any of a mixture of fence types (wsi, driver or syncobjs)
causes the driver to poll, while a list of just syncobjs or
just driver fences will block. When we get syncobjs for wsi
fences, we'll adapt to use them.

v3: Adopt Jason Ekstrand's coding conventions

Declare variables at first use, eliminate extra whitespace between
types and names. Wrap lines to 80 columns.

Suggested-by: Jason Ekstrand <jason.ekstrand@intel.com>
v4: Adapt to WSI fence API change. It now returns VkResult and
no longer has an option for relative timeouts.

v5: wsi_register_display_event and wsi_register_device_event now
use the default allocator when NULL is provided, so remove the
computation of 'alloc' here.

v6:
    Change WSI fence wait function to return VkResult instead of
    bool. This makes the meaning of the return value easier to

    Also change the WSI fence wait function to take only absolute
    timeouts and not provide an option for a relative timeout. No
    users wanted relative timeouts, and it's simpler if that option
    isn't available.

    Terminate the DPMS property loop once we've found the property.

    Assert that the fence hasn't already been destroyed in
    wsi_display_fence_destroy.

    Rearrange the event handler function order in the file to place
    routines in an easier to find order.

v9:

Suggested-by: Jason Ekstrand <jason.ekstrand@intel.com>
v10:
    Use wsi->alloc if none provided in wsi_display_fence_alloc.

    Now that drivers are expected to pass the allocator argument
    straight through from the application, we need to check those
    for NULL everywhere.
