We don't actually need to extend g0's live range to the EOT message
generally - most messages that end a shader are headerless. The main
implicit use of g0 is for constructing scratch headers. With the last
two patches, we now consider scratch access that may exist in the IR
and already extend the liveness appropriately.
There is one remaining problem: spilling. The register allocator will
create new scratch messages when spilling a register, which need to
create scratch headers, which need g0. So, every new spill or fill
might extend the live range of g0, which would create new interference,
altering the graph. This can be problematic.
However, when compiling SIMD16 or SIMD32 fragment shaders, we don't
allow spilling anyway. So, why not use allow g0? Also, when trying
various scheduling modes, we first try allocation without spilling.
If it works, great, if not, we try a (hopefully) less aggressive
schedule, and only allow spilling on the lowest-pressure schedule.
So, even for regular SIMD8 shaders, we can potentially gain the use
of g0 on the first few tries at scheduling+allocation.
Once we try to allocate with spilling, we go back to reserving g0
for the entire program, so that we can construct scratch headers at
any point. We could possibly do better here, but this is simple and
reliable with some benefit.
Thanks to Ian Romanick for suggesting I try this approach.

brw_send_indirect_split_message() implicitly reads g0 to construct the

The generator code for emitting legacy scratch headers was implicitly
using g0 as a source. But the IR wasn't indicating any usage of g0,
which means the liveness isn't properly tracked at the IR level.
It works because we reserve g0 as permanently live for the whole
program. In order to stop doing that, we need to record it properly.

API requires samplers to return 32-bit even though hardware can handle
16-bit floating point, so we detect that case and make more efficient
use of memory BW. This is helping improve performance of encode and

While extending our backend to handle 16-bit sampler return payloads, we
found that in piglit's arb_texture_view-rendering-formats, the SIMD8 FS
was missing the sampling operation altogether. This was because we were
first emitting the texturing instruction, and then calling
get_nir_def(), which adds an UNDEF instruction when the destination is
smaller than the 32-bit. So the texturing was dead code elimated. Fix
this by calling get_nir_def() earlier.
