This adds a number of tests that check that all types will match to
identically written clones during linking, including nearly every Type
and some combinations (e.g. Functions of Arrays of Floats). Intent is
for use with https://github.com/KhronosGroup/SPIRV-Tools/pull/2580,
however that PR focuses on issues with TypeArray whereas these tests are
(more) comprehensive and test more subtle (and possibly incorrect)
cases.
A number of these tests fail, many are fixed by the aforementioned PR.
Some additional tests involving TypeForwardPointer are currently
disabled as they cause assertion failures.
Fixes#2604
* Allow selection constructs to branch to the nearest selection merge
whose header is terminated by an OpSwitch
* Cleanup break and continue checks generally
* add tests
In order to try to reduce code duplication and to be able
to fold more cases, we want to use the instruction folder
when folding an OpSpecConstantOp with constant operands.
A couple other changes are need to make this work. First
GetDefiningInstruction| in the constant manager is able
to handle |type_id| being logically equivalent to another
type, so we updated the interface, and removed the assert.
Some tests were also updated because we not generate
better code because constants are not duplicated as much
as before.
No need for new tests. The functionality of the instruction folder is
already tested. There are tests check that the instruction folder is
being used correctly for OpCompositeExtract and OpVectorShuffle in the
existing test cases.
Fixes#2585.
It is currently not possible to use an Image Format that is
not Unknown without requiring a capability forbidden by the
OpenCL environment. As such the validation of Image Format
currently leans on capability validation entirely.
Fixes#2592.

Validate structured exits from constructs
* Add checks that exits from a construct are valid
* Add Construct::IsStructuredExit()
* uses specific rules for each type of construct
* Added a test and check for #2213
* Adding tests for bad loop and continue exits
* Fix identification of continue block that prevented some selections
from having any blocks
* Update memory model support for SPIR-V 1.4
Fixes#2552
* Upgrade memory model now supports two memory access operands for
OpCopyMemory*
* in all cases the pass will first generate two operands by either
adding them or copying
* updates accounts for multiple operands
* tests
There is a case where sroa is not handling id overflow gracefully. It
is handled and an error message is output when the ids overflow.
Fixes https://crbug.com/961030.
* Make pointers to logically matching types interchangeable with option.
DXC will be generating code where the function parameters will be a more
generic type that the actual parameter. They should be logically
matching and the decorations of the actual parameter must be a superset
of the decorations of the formal parameter.
We want to accept this code with an options so that spirv-opt can then
inline and fix the type mismatch. We will accept this under a new
options `--before-hlsl-legalization`.
The new option will also imply `relax-logical-pointer` so that HLSL
frontends will need to use just the one more generic option.
Moved the |LogicallyMatches| to the validation state to make it
available in more places. Also added a parameter to have it check the
decorations. I did not do a separate function for the decorations
because checking the decorations involves making sure the types
logically match anyway.
Fixes#2535
* Use grammar last version
Fixes#2560
* Parse last version and use it in checks
* Update grammar header generation
* Fix NonWritable tests
* Fix check and add specific tests
Fixes#2555
* Fix a bug in validation where interfaces were considered non-unique
between different entry points targeting the same function
* added a test
* Update private to local pass to remove localized private variables
from entry point interfaces
* added tests
Fixes#2551
* Add support for 1.4 entry point interface lists
* only input and output variables are automatically live
* can clean up interfaces after DCE
* added tests
* allow opt tests to specify a target environment
The 'is' operator is not meant to be used for comparisons. It currently working is an implementation detail of CPython.
CPython 3.8 has added a SyntaxWarning for this.
* SPIR-V 1.4 headers, add SPV_ENV_UNIVERSAL_1_4
* Support --target-env spv1.4 in help for command line tools
* Support asm/dis of UniformId decoration
* Validate UniformId decoration
* Fix version check on instructions and operands
Also register decorations used with OpDecorateId
* Extension lists can differ between enums that match
Example: SubgroupMaskEq vs SubgroupMaskEqKHR
* Validate scope value for Uniform decoration, for SPIR-V 1.4
* More unioning of exts
* Preserve grammar order within an enum value
* 1.4: Validate OpSelect over composites
* Tools default to 1.4
* Add asm/dis test for OpCopyLogical
* 1.4: asm/dis tests for PtrEqual, PtrNotEqual, PtrDiff
* Basic asm/Dis test for OpCopyMemory
* Test asm/dis OpCopyMemory with 2-memory access
Add asm/dis tests for OpCopyMemorySized
Requires grammar update to add second optional memory access operand
to OpCopyMemory and OpCopyMemorySized
* Validate one or two memory accesses on OpCopyMemory*
* Check av/vis on CopyMemory source and target memory access
This is a proposed rule. See
https://gitlab.khronos.org/spirv/SPIR-V/issues/413

* Validate NonWritable decoration
Also permit NonWritable on members of UBO and SSBO.

* Add 1.4 validation for pointer comparisons
* New tests
* Validate with image operands SignExtend, ZeroExtend
Since we don't actually know the image texel format, we can't fully
validate. We need more context.
But we can make sure we allow the new image operands in known-good
cases.

to instead use the version from the binary

1.4 environment
* Fix test for update to SPIR-V 1.4 headers
* Fix formatting
* Ext inst lookup: Add Vulkan 1.1 env with SPIR-V 1.4

* Operand version checks should use module version
Use the module version instead of the target environment version.
* Fix comment about two-access form of OpCopyMemory
Add functionality to fix-storage-class so that it can fix up mismatched
data types for pointers as well.
Fixes bugs in when fixing up storage class.
Move GenerateCopy to the Pass class to be reused.
The spirv-opt change for #2535.
* Change implementation of post order CFG traversal
It seems like the recursion is going very deep, and causing some problem
is particular situations. I've reimplemented the CFG post order
traversal to not use recursion.
Fixes#2539.
There was a bit shift done on 32-bit values, but they should have been
done on 64-bit values. This is fixed. At the same time, uses of size_t
are repalaced by uint64_t to ensure these values are 64-bit.
A test case cannot be created because the code that was change is not
run at the moment since we do not split up vectors or matricies. I do
not want to delete the code because I like to experitment with it every
once in a while.
Fixes#2528.
