With some bit magic, we can get something much nicer:

  v_add_u32     v0, s2, v0                              // 000000000000: 68000002

  v_mul_f32     v1, 0.5, v1                             // 000000000010: 0A0202F0

  v_mov_b32     v2, 0                                   // 000000000020: 7E040280
  v_mov_b32     v3, 1.0                                 // 000000000024: 7E0602F2

  exp           param0, off, off, off, off              // 000000000030: C4000200 00000000
  s_endpgm                                              // 000000000038: BF810000

The above output was based on just shoving it in ShaderPlayground -- I was not able to use pipeline feedback as I was unable to get RenderDoc working due to the EXT_physical_device_drm requirement.

I additionally considered using >> 1 instead of * 0.5, but AMD has dedicated modifiers to merge a * 0.5, * 2.0, etc in a single instruction. (Albeit, not taken advantage of in the code above, but might with ACO)

1d9c1bcea6 input-device: remove wlr_input_device.link 
This field's ownership is unclear: it's in wlr_input_device, but
it's not managed by the common code, it's up to each individual
backend to use it and clean it up.

Since this is a backend implementation detail, move it to the
backend-specific structs.

3b93da70a0 backend/wayland: report parent presentation clock 
There's no guarantee that the parent Wayland compositor uses
CLOCK_MONOTONIC for reporting presentation timestamps, they could
be using e.g. CLOCK_MONOTONIC_RAW or another system-specific clock.

Forward the value via wlr_backend_impl.get_presentation_clock.

d0bb7df630 output: remove XRGB8888 cursor fallback format 
All graphics drivers supporting cursor planes support ARGB8888,
the default cursor format, so this fallback is almost certainly
unused.

Essentially all cursor themes use alpha transparency to make it
clearer where relative to the screen content the cursor hotspot is.
It is better to fall back to a slightly slower software cursor than
it is to fall back to the opaque square that is a hardware cursor
without an alpha channel.

e879d566bb output: Add function to set preferred render format 
This change introduces new double buffered state to the wlr_output,
corresponding to the buffer format to render to.

The format being rendered to does not control the bit depth of colors
being sent to the display; it does generally determine the format with
which screenshot data is provided. The DRM backend _may_ sent higher
bit depths if the render format depth is increased, but hardware and
other limitations may apply.

3d7d6ec06f output: use XRGB8888 format instead of ARGB8888 
Most (and possibly all) compositors using wlroots only ever render
fully opaque content. To provide better performance, this change
switches the default format used by wlr_output buffers from
ARGB8888 to the opaque XRGB8888.

Compositors like mutter, kwin, and weston already default to
XRGB8888, so this change is unlikely to expose any new bugs in
underlying drivers and hardware.

This does not affect the hardware cursor's buffer format, which is
still ARGB8888 by default.

As part of this change, the X11 backend (which does not support
changing format at runtime) now picks a true color, 24 bit depth
visual (i.e. XRGB8888) instead of a 32 bit depth (ARGB8888) one.

33eba9080c output: fix renderer buffer cap sanity check in wlr_output_init_render 
The backend and renderer don't directly interact together, so there's
no point in checking that their buffer caps intersect. What we want to
check is that:

- The backend and allocator buffer caps are compatible, because the
  backend consumes buffers to display them.
- The renderer and allocator buffer caps are compatible, because the
  renderer imports buffers to sample them or render to them.

For instance, when running with the DRM backend and the Pixman renderer,
the (backend & renderer) check will fail because backend = DMABUF and
renderer = DATA_PTR.
