The VBO module maps a buffer with GL_MAP_FLUSH_EXPLICIT, and keeps
appending data, and calling glFlushMappedBufferRange(). We were
invalidating the VF cache each time it flushed a new range, which
results in a ton of VF flushes.
If the contents of the destination in the target range are undefined
(never even possibly written), this patch makes us assume that it's
likely not in the cache and so cache invalidations are required. If
the destination range is defined, we continue cache flushing as we may
need to expunge stale data.
This eliminates 88% of the VF cache invalidates on Manhattan 3.0.
Improves performance in Manhattan 3.0 on my Icelake 8x8 with the GPU
frequency locked to 700Mhz by 0.376724% +/- 0.0989183% (n=10).
This cuts roughly 85% of the 3DSTATE_SAMPLER_STATE_POINTERS_PS calls in
the J2DBench images test. For some reason, the state tracker is calling
bind_sampler_state with the same sampler state in a bunch of cases.
The line stipple pattern and factor only matter if line stippling is
actually enabled. Otherwise, we can safely ignore it.
PBO upload may give us zero for line stipple information, while normal
drawing tends to give us an actual stipple pattern such as 0xffff. This
was causing us to flag IRIS_DIRTY_LINE_STIPPLE way too often, leading to
useless 3DSTATE_LINE_STIPPLE commands, which are non-pipelined and thus
very expensive.
Improves performance in Manhattan 3.0 on Skylake GT4e by
0.149261% +/- 0.0380796% (n=210). On an Icelake 8x8 with the GPU

These are supposed to be lowered into sge/slt/seq/sne equivalents.

The entire point of schedule_first is that the node has to be scheduled
as soon as possible without any moves because it doesn't produce a
proper floating-point value, or its value changes depending on where you
read it. We were still introducing a move for preexp2 in some cases
though, even if it got scheduled as soon as possible, which broke some
exp() tests. Fix that.

The whole point of schedule_first nodes is that they need to be
scheduled as soon as possible, so if a schedule_first node is the
successor in a fake dependency that prevents it from being scheduled
after its parent, that can cause problems. We need to add these fake
dependencies to the parent as well, and we need to guarantee that the
pre-RA scheduler puts schedule_first nodes right before their parents in
order to prevent this from adding cycles to the dependency graph.

The point of the function is to avoid creating a complex move which is
used by certain slots in the next instruction, but unscheduled
successors will never be in the next instruction. Found while debugging

The scheduler assumes that load nodes are always duplicated so that they
can always be scheduled eventually and therefore they never need to be
spilled. But some lowerings were running after the pre-RA scheduler,
whereas duplication has to happen before then since it's needed for the
scheduler to do a better job reducing register pressure. This meant
that lowerings were introducing multiple uses of a load instruction,
which broke the scheduler's expectation and resulted in infinite loops
in situations where the only nodes available to spill were load nodes.
Spilling load nodes would be silly, so we want to fix the lowerings
rather than the scheduler. Just do all lowerings before the pre-RA
scheduler, which also helps with reducing pressure since the scheduler
can more accurately compute the pressure.

The dead_cf pass calls into the CF manipulation helpers which attempt to
keep NIR's SSA form sane. However, when the only break is removed from
a loop, dominance gets messed up anyway because the CF SSA clean-up code
only looks at phis and doesn't consider the case of code becoming
unreachable. One solution to this would be to put the loop into LCSSA
form before we modify any of its contents. Another (and the approach
taken by this pass) is to just run the repair_ssa pass afterwards
because the CF manipulation helpers are smart enough to keep all the
use/def stuff sane; they just don't always preserve dominance
properties.
While we're here, we clean up some bogus indentation.

NIR currently assumes that unreachable blocks are trivially dominated by
everything. However, when considering well-formed SSA, there is no path
from any block to an unreachable block. Therefore, we can break any
use-def chains where the use is in an unreachable block. This removes
any dependencies on code created by uses in unreachable blocks and lets
DCE do a better job of cleaning it up.
