Fixes#3529
* Make BasicBlock::reachable() only consider static reachability
* Fix reachability calculation to be independent of block order
* add tests
* Add validation that input/output locations are assigned correctly
* Account for component assignment
* Account for 4 components per location and track the combined
coordinate
* Account for multiple output indexes
* handle specifically arrayed variables
* Arrayed variables that specify a component get locations determined
per index of the array for the sub type
* Added tests that check locations and components can be assigned
to interleave an array's locations and components
* Fix up which interfaces are allowed to be arrayed for various shader
stages based on glslang
ImageGatherBiasLodAMD makes it possible to use the Bias and Lod image
operands with OpImageGather and OpImageSparseGather. This commit makes
sure the validator checks for that capability before reporting errors
and adds a few positive tests.
According to SPV_AMD_shader_image_load_store_lod spec, Lod operand is
valid with OpImageRead, OpImageWrite, or OpImageSparseRead if the
extension is enabled.
Fixes#3139
* If the header of the construct is also a merge block, jump to the
associated header instead of the immediate dominator
* prevents spurious failures from unrelated constructs
* new tests
* Allow OpExtInst for DebugInfo between secion 9 and 10
Fixes#3086
* Handle spirv-opt errors on DebugInfo Ext
* Add IR Loader test
* Fix ir loader bug
* Handle DebugFunction/DebugTypeMember forward reference
* Add test cases (forward reference to function)
* Support old DebugInfo extension
* Validate local debug info out of function
Add support for SPV_KHR_non_semantic_info
This entails a couple of changes:
- Allowing unknown OpExtInstImport that begin with the prefix `NonSemantic.`
- Allowing OpExtInst that reference any of those sets to contain unknown
ext inst instruction numbers, and assume the format is always a series of IDs
as guaranteed by the extension.
- Allowing those OpExtInst to appear in the types/variables/constants section.
- Not stripping OpString in the --strip-debug pass, since it may be referenced
by these non-semantic OpExtInsts.
- Stripping them instead in the --strip-reflect pass.
* Add adjacency validation of non-semantic OpExtInst
- We validate and test that OpExtInst cannot appear before or between
OpPhi instructions, or before/between OpFunctionParameter
instructions.
* Change non-semantic extinst type to single value
* Add helper function spvExtInstIsNonSemantic() which will check if the extinst
set is non-semantic or not, either the unknown generic value or any future
recognised non-semantic set.
* Add test of a complex non-semantic extinst
* Use DefUseManager in StripDebugInfoPass to strip some OpStrings
* Any OpString used by a non-semantic instruction cannot be stripped, all others
can so we search for uses to see if each string can be removed.
* We only do this if the non-semantic debug info extension is enabled, otherwise
all strings can be trivially removed.
* Silence -Winconsistent-missing-override in protobufs
* Validate that if a construct contains a header and it's merge is
reachable, the construct also contains the merge
* updated block merging to not merge into the continue
* update inlining to mark the original block of a single block loop as
the continue
* updated some tests
* remove dead code
* rename kBlockTypeHeader to kBlockTypeSelection for clarity
Re-enable OpReadClockKHR validation
Fixes#2952
* Refactor some common scope validation
* Perform correct validation for scope in OpReadClockKHR
* Scope must be Subgroup or Device
* new tests
* Validate that selections are structured
WIP
* new checks that switch and conditional branch are proceeded by a
selection merge where necessary
* Don't consider unreachable blocks
* Add some tests
* Changed how labels are marked as seen
* Moved check to more appropriate place
* Labels are now marked as seen when there are encountered in a
terminator instead of when the block is checked
* more tests
* more tests
* Method comment
* new test for a bad case
* When input or result is a pointer type also allow 32-bit integer
vectors for the other type
* Relaxation only applies to SPIR-V 1.5 or in the presence of
SPV_KHR_physical_storage_buffer
* new tests
* Vulkan specific checks
* storage buffer variables must be structs or arrays of structs
* storage buffer struct must be Block decorated
* uniform struct must be Block or BufferBlock decorated
* new tests
* Ensure same enum values have consistent extension lists
* val: fix checking of capabilities
The operand for an OpCapability should only be
checked for the extension or core version.
The InstructionPass registers a capability, and all its implied
sub-capabilities before actually checking the operand to an
OpCapability.
* Add basic support for SPIR-V 1.5
- Adds SPV_ENV_UNIVERSAL_1_5
- Command line tools default to spv1.5 environment
- SPIR-V 1.5 incorporates several extensions. Now the disassembler
prefers outputing the non-EXT or non-KHR names. This requires
updates to many tests, to make strings match again.
- Command line tests: Expect SPIR-V 1.5 by default
* Test validation of SPIR-V 1.5 incorporated extensions
Starting with 1.5, incorporated features no longer require
the associated OpExtension instruction.
As far as I know, it is legal to have multiple decoration adding the
same decoration to the same id. The validator registers all of these
decoration as if they were distinct decorations. This can cause poor
memory usage and performance in some cases.
This fix is to make sure that duplicates are not registers.
I keep the type of the decoration list as an std::vector because I
expect it to be small enough in most cases that the linear search will
still be faster that using some type of map.
No tests are added because we do not have a mechanism to test memory
usage in our unit tests.
Fixes#2837. The total memory usage drop to 14,236KB.
Fixes#2793
* Don't special case matrix validation compared to other composites
* just check the constituents are constants or undefs
* later checking validates the column type
* new test
* Process OpDecorateId in ADCE
When there is an OpDecorateId instruction that is live,
the ids that is references must be kept live. This change
adds them to the worklist.
I've also updated a validator check to allow OpDecorateId
to be able to apply to decoration groups.
Fixes#1759.
* Remove dead code.
This change refactors all storage class validation for atomics
to reflect the similar refactoring in the specification.
It is currently not possible to write a test for the check
rejecting Generic in an OpenCL 1.2 environment as the required
GenericPointer capability isn't allowed there. I've decided
to keep the check nonetheless to guard against the capability
becoming available without the rules for atomics being updated.
The ID changes in existing tests aren't ideal but introducing
names drags in a substantial refactoring of this file.
Contributes to #2595.
