This adds two passes to accomplish this: one pass to analyze a shader
to determine the input slots that are live. The second pass is run on
the preceding shader to eliminate any stores to output slots that are
not consumed by the following shader.
These passes support vert, tesc, tese, geom, and frag shaders.
These passes are currently only available through the API.
These passes together with dead code elimination, and elimination of
dead input and output components and variables (WIP), will allow users
to do dead code elimination across shader boundaries.
Fixes#4918
* Prevent block merging from producing an invalid case construct by
merging a switch target/default with another construct's merge or
continue block
* This is to satisfy the structural dominance requirement between the
switch header and the case constructs
Fixes#4671
Fixes https://crbug.com/oss-fuzz/43265
* Only validate full layout in a vulkan environment
* Universal validation still checks that the right decorations are
present, but the values are only considered for vulkan
* One exception is that invalid overlaps are only checked for vulkan
* This is a pragmatic choice as SPIR-V doesn't define the size of
types so the amount of universal checking would be quite limited
* Removed redundant check for GLSLShared and GLSLPacked decorations
* Should never have been validated as part of universal validation
* make conditionals independent
Fixes https://crbug.com/oss-fuzz/48553
* Assign a reflexive dominator if no other dominator can be found using
forward traversals
* This prevents a null dereference of a pointer in the sorting of the

* Support Narrow Types in BitCast Folding Rule
This change adds support for narrow types in the BitCastScalarOrVector
folding rule. According to Section 2.2.1 of the SPIR-V spec, types that
are narrower than 32 bits are automatically either sign extended, or
zero extended depending on the type. With that guaranteed, we should
be able to use the first 32-bit word of any narrow type for the folding
logic without performing any special conversions.
In order to reduce code duplication, this change moves the
GetU32BitValue and GetU64BitValue functions from IntConstant to
ScalarConstant. Without this move, we would have needed an identical
version of GetU32BitValue on FloatConstant.
* Add Tests for 16-bit BitCast Folding
This change adds several new test cases to the
IntegerInstructionFoldingTest which trigger the 16-bit BitCast logic.
The logic for half types was also added to the integer case since we
can't easily validate half float types in C++ code. It's easier to
validate them as unsigned integers instead. Pllus this also allows us
to verify the SPIR-V constant sign extension logic too.
* Add 8-Bit Folding Test Cases
This change adds a couple more test cases to the integer instruction
folding test suite in order to ensure that the BitCast logic also
works correctly with the Int8 shader capability.
The always-friendly messages make it harder to debug when the
disassembly is later generated without friendly names.
Additionally, the friendly-name-mapper is slow. Disabling it improves
performance of an ANGLE test that creates numerous shaders by ~5%.
Half the messages used to output 'id[%name]' and half id[%name]. With
this change, all messages consistently output 'id[%name]'. Some typos
are also fixed in the process.
This was spotted in the Validation Layers where OpSpecConstantOp %x CompositeExtract %y 0 was being folded to a constant, but anything that was using it wasn't recognizing it as a constant, the simple fix was to add a const_mgr->MapInst(new_const_inst); so the next instruction knew it was a const
* Remove `spvOpcodeTerminatesExecution`
This function is the same as `spvOpcodeIsAbort` except for
OpUnreachable. The names are so close in meaning that it is hard to
distinguish them. I've removed `spvOpcodeTerminatesExecution` since it
is used in only a single place. I've special cased OpUnreachable in
that location.
At the same time, I fixed up some comments related to the use of the
TerminatesExecution and IsAbort functions.
Following up on #4930.
* Fix comments
Removed now unused DebugDeclare visibility logic for generating
DebugValue.
Also eliminated the phi sort introduced in 272e4b3. This should have
been removed in the first commit.
Changed a couple small parts of the algorithm to reduce time to build
the dominator trees. There should be no visible changes.
Add a depth first search algorithm that does not run a function on
backedges. The check if an edge is a back edge is time consuming, and
pointless if the function run on it is a nop.
Add name annotations to the generated instrumentation code to
make it easier to understand. Example spirv-cross output:
vec4 _140;
if (0u < inst_bindless_direct_read_4(0u, 0u, 1u, uint(_19)))
{
_140 = texture(textures[nonuniformEXT(_19)], inUV);
}
else
{
inst_bindless_stream_write_4(50u, 1u, uint(_19), 0u);
_140 = vec4(0.0);
}
