The later, more generic function will be used in the intra-stage linker.
|
|
|
|
|
|
It is a lot simplier, cleaner, and more stable now.
|
|
The instruction can be hung off of any other in the tree, even if the
other one will be deleted, since it'll get stolen to the shader's
context later if it's still live.

Fixes glsl-vs-vec4-indexing-3.
|
|
We would clear the in_lhs flag early, avoiding copy propagation on the
array index variable (oops) and then copy propagating on the array
variable (ouch). Just avoid all copy propagation on the LHS instead.

Add two invariant checks related to functions and function signatures:
1. Ensure that function definitions (ir_function) are not nested.
2. Ensure that the ir_function pointed to by an ir_function_signature
is the one that contains it in its signatures list.
|
|
There is no setter function, the getter returns a constant pointer,
and ir_function_signature::_function is private for a reason. The
only way to make a connection between a function and function
signature is via ir_function::add_signature. This helps ensure that
certain invariants (i.e., a function signature is in the list of
signatures for its _function) are met.

Temporary variables added for &&, ||, and ?: were not being added to
the instruction stream. This resulted in either test failures or
Valgrind being angry after the original IR tree was destroyed by
talloc_free. The talloc_free caused the ir_variables to be destroyed
even though they were still referenced.

Fix r600_context.h -> r700_oglprog.h -> r600_context.h include
recursion.

Fixes glsl-fs-uniform-array-1, glsl-vs-uniform-array-1, and the -2
tests on software.

This reverts commit b4d0c0e0ee983ee614b047799c3e01221a353c98.
Now that ir_mat_op_to_vec is landed, this change is no longer needed.
|
|
This will be used by the Mesa IR and likely most HW backends, as it
allows other optimizations to occur that might not otherwise.
Fixes glsl-vs-mat-sub-1, glsl-vs-mat-div-1.

Need to flush command stream before mapping texture image
that is referenced by current cs.
Candidate for 7.8 branch.

This feels a little odd, but it will be useful for ir_mat_to_vec,
where I want to see a plain assignment of the expression to a
variable, not to a writemasked array dereference with a call as the
array index.
|
|
It would be easy to miss an entry either of the two visitors involved
that would result in trying to ir->remove() the call to remove it from
the instruction stream when really it's part of an expression tree
that wasn't flattened.

There's already an implementation of pipe_barrier using
the other pipe_* primitives; just use that on Windows, too.
Now Windows passes pipe_barrier_test.
|
|
The new default implementation of pipe_condvar makes it
unnecessary.
|
|
Unfortunately compiling with these defines enabled would mean
Gallium can't run on Windows XP/2003 or older.
Todo: Need a macro to declare if we don't care about WinXP
compatibililty.
|
|
Or at least a little of it. This version will sleep
for a fixed amount of time instead of just deadlocking,
which is a slight improvement.
Also do the same thing on any unrecognized platform.

An initial implementation made by Dave Airlie.
For it to be used, a color-only clear must be invoked and exactly one
point-sampled render target must be set. The render target must be
macrotiled (for us to overcome alignment issues) and bpp must be either
16 or 32.
I can't see a difference in performance. :(

With an ordinary quad, the pixels on the main diagonal are computed
and stored twice, which is somewhat inefficient and might not work well
with specialized clear codepaths.
|
|
And other minor fixups.

FDO bug #28563.
|
|
When searching for valid miptree check images in range
of [BaseLeve, MaxLevel] not [MinLod, MaxLoad].
Prevents unnecessary miptree allocations in cases when during
every rendering operation different texture image level
was selected using MIN_LOD = MAX_LOD = level (for every level
new miptree for whole texture was allocated).
Candidate for 7.8 branch.

Always store selected miptree in texObj->mt so get_base_teximage_offset returns correct data.
Found with piglit/mipmap-setup.
Candidate for 7.8 branch.
