We need to keep track if a state change other than frag/vert shader
state will trigger us to need a different shader variant, and if
necessary mark the appropriate shader state as dirty. Otherwise we will
forget to re-emit the shader state.

Keep the existing function as a common helper. But this lets us move an
a2xx specific hack out of common code. And the PIPE_TEX_WRAP_CLAMP
emulation will require an a3xx specific hack. So rather than piling on
hacks, split this out.

Still some open questions.. and at any rate, no additional piglit passes

cases :-(
But it does fix some mystery page-faults.. So add some comments in the
code where there are things that we need to emulate or do more r/e, and
push as-is.

Previously we would get a potentially computed post-swizzle coord based

The second argument does not have to be adjacent, so adjusting the order

(cherry picked from commit 18291ee17a)
4f338c9b introduced logic to trigger a flush rather than overflowing
cmdstream buffer. But the threshold was too low, triggering flushes
where they were not needed. This caused problems with games like
xonotic.
Part of the problem is that we need to mark all state dirty between
cmdstream submit ioctls, because we cannot rely on state being
preserved across ioctls. But even with that, there are still some
problems that are still being debugged. For now:
1) correctly mark all state dirty
2) introduce FD_MESA_DEBUG flush flag to force rendering to be flushed
between each draw, to trigger problems (so that I can debug)
3) use a more reasonable threshold so for normal usecases we don't
trigger the problems
This at least corrects the regression, but there is still more debugging
to do.

Because of render-to-alpha (000x) shenanigans, freedreno needs to do
some special handling when rendering to alpha-only formats. And I
noticed that while we had _is_luminance(), _is_intensity(), etc, an
_is_alpha() helper was missing. So fix that.

Since software primitive-restart emulation is going to be removed (and

We currently aren't too clever about dealing with running out of
cmdstream buffer space. Since we use a single buffer for both drawing
and tiling commands, we need to ensure there is enough space at the tail
of the cmdstream buffer to fit the tiling commands.
Until we get more clever, the easy solution is a threshold to trigger
flushing rendering even if the application does not trigger flush (swap,
changing render target, etc). This way we at least don't crash for apps
that do several thousand draw calls (like some piglit tests do).

Most of the things the new compiler still has trouble with basically
amount to cp stage removing too many copies. But without the cp stage,
the shaders the new compiler produces are still better (perf and
correctness) than the old compiler. So a simple thing to do until I
have more time to work on it is first trying falling back to new
compiler without cp, before finally falling back to old compiler.

all_delayed will also be true if we didn't attempt to schedule anything
due to no more instructions using current addr/pred. We rely on coming
in to block_sched_undelayed() to detect and clean up when there are no
more uses of the current addr/pred, which isn't necessarily an error.
This fixes a regression introduced in b823abed.

There are some cases where the scheduler can get itself into impossible
situations, by scheduling the wrong write to pred or addr register
first. (Ie. it could end up being unable to schedule any instruction if
some instruction which depends on the current addr/reg value also
depends on another addr/reg value.)
To solve this we'd need to be able to insert extra mov instructions
(which would also help when register assignment gets into impossible
situations). To do that, we'd need to move the nop padding from sched
into legalize.
But to start with, just detect when we get into an impossible situation
and bail, rather than sitting forever in an infinite loop. This way it
will at least fall back to the old compiler, which might even work if
you are lucky.
