We were missing handling for a few other ops that rearrange their
sources somehow in codegen, namely complex2 and select.

5 years agolima/gpir/sched: Don't try to spill when something else has succeeded
Connor Abbott [Sat, 27 Jul 2019 16:31:09 +0000 (18:31 +0200)]
lima/gpir/sched: Don't try to spill when something else has succeeded

In try_node(), we assume that the node we pick can still be scheduled
successfully after speculatively trying all the other nodes. Normally we
always undo every node after speculating it, so that when we finally
schedule best_node the scheduler state is exactly the same and it
succeeds. However, we also try to spill nodes, which can change the
state and in a corner case that can make scheduling best_node fail. In
particular, the following sequence of events happened with piglit
shaders@glsl-vs-if-nested: a partially-ready node N was spilled and a
register store node S, which is a use of N, was created and then later
the other uses of N were scheduled, so that S is now ready and N is
partially ready. First we try to schedule S and succeed, then we try to
schedule another node M, which fails, so we try to spill the remaining
uses of N. This succeeds, but scheduling M still fails so that best_node
is still S. However since one of the uses of N is one cycle ago, and
therefore we inserted a read dependent on S one cycle ago when spilling
N, S can no longer be scheduled as read-after-write latency is three
cycles.

While we could ad-hoc try to catch cases like this, or (the best option
but very complicated) treat the spill as speculative and roll it back if
we decide not to schedule the node, a simpler solution is to just
give up on spilling if we've already successfully speculatively
scheduled another node. We'd give up a few cases where we discover that
by spilling even harder we could schedule a more desirable node, but
that seems like it would be pretty rare in practice. With this we
guarantee that nothing has been touched after best_node was successfully
scheduled. We also cut down on pointless spilling, since if we already
scheduled a node it's unlikely that spilling harder will let us schedule
an even better node, and hence any spilling at this point is probably
useless.

While we're here, clean up the code around spilling by flattening the
two if's and getting rid of the second unnecessary check for INT_MIN.

Iago Toral Quiroga fixed this in commit 94f740e3fce0cb26e4d90cb9de75b,
but it recently regressed in 0d8826f723cd8868b5271f17f18a1ab4548a1199.
Quoting Iago's original commit message for the fix:

GetTex*Image should return INVALID_ENUM if target is not valid, however,
GetTextureImage does not receive a target, and instead should return
INVALID_OPERATION if the effective target is not valid.  From the
OpenGL 4.6 core profile spec, section 8.11 Texture Queries:

   "An INVALID_OPERATION error is generated by GetTextureImage if the
    effective target is not one of TEXTURE_1D, TEXTURE_2D, TEXTURE_3D,
    TEXTURE_1D_ARRAY, TEXTURE_2D_ARRAY, TEXTURE_CUBE_MAP_ARRAY,
    TEXTURE_RECTANGLE, or TEXTURE_CUBE_MAP (for GetTextureImage only)."

Note that this differs from the original ARB_direct_state_access spec.

However, the EXT_direct_state_access version does take a target
parameter, so it should continue reporting INVALID_ENUM.
