* 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 operation for OpSpecConstantOp
* Validate NonWritable decoration
Also permit NonWritable on members of UBO and SSBO.
* SPIR-V 1.4: NonWrtiable can decorate Function and Private vars
* Update optimizer CLI tests for SPIR-V 1.4
* Testing tools: Give expected SPIR-V version in message
* SPIR-V 1.4 validation for entry point interfaces
* Allow only unique interfaces
* Allow all global variables
* Check that all statically used global variables are listed
* new tests
* Add validation fixture CompileFailure
* 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.
* Validate OpCopyLogical
* Recursively checks subtypes
* new tests
* Add SPIR-V 1.4 tests for NoSignedWrap, NoUnsignedWrap
* Allow scalar conditions in 1.4 with OpSelect
* Allows scalar conditions with vector operands
* new tests
* Validate uniform id scope as an execution scope
* Validate the values of memory and execution scopes are valid scope
values
* new test
* Remove SPIR-V 1.4 Vulkan 1.0 environment
* SPIR-V 1.4 requires Vulkan 1.1
* FIX: include string for spvLog
* FIX: validate nonwritable
* FIX: test case suite for member decorate string
* FIX: test case for hlsl functionality1
* Validation test fixture: ease debugging
* Use binary version for SPIR-V 1.4 specific features
* Switch checks based on the SPIR-V version from the target environment
to instead use the version from the binary
* Moved header parsing into the ValidationState_t constructor (where
version based features are set)
* Added new versions of tests that assemble a 1.3 binary and validate a
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
* Update spirv-val help
* 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
This pass tries to fix validation error due to a mismatch of storage classes
in instructions. There is no guarantee that all such error will be fixed,
and it is possible that in fixing these errors, it could lead to other
errors.
Fixes#2430.
Updated script to work with python3 and python2.
Added required tools.
We added a section to the readme to mention the tools that are needed to
build and test spirv-tools. For the compiler, the compilers used by the
bots are mentioned.
The bots have been changed. The windows bots will not use python 3.6 for testing. The other bots will still use python 2.7. Both Python2 and Python3 will be tested.
Fixes#2407.
Fixes#1856.
When processing options in a file, it does have access to the
ValidatorOptions and OptimizerOptions object, so options that change
those do not work. We just need to pass it in.
Fixes#2219.
This CL takes the various opt unit tests and makes a single executable
instead of one per test. This reduces the number of build targets by
~125 when building with ninja.
Merge return assumes that the only unreachable blocks are those needed
to keep the structured cfg valid. Even those must be essentially empty
blocks.
If this is not the case, we get unpredictable behaviour. This commit
add a check in merge return, and emits an error if it is not the case.
Added a pass of dead branch elimination before merge return in both the
performance and size passes. It is a precondition of merge return.
Fixes#1962.
A limit of 0 for the scalar replacement options it used to indicate that
there is no limit. The current implementation does not allow 0. This
should be fixed.
Adds unrolling to the legalization passes.
After enabling unrolling I found a bug when there is a self-referencing
phi node. That has been fixed.
The test that checks for that the order of optimizations is correct also
needed to be updated.
This forks the testing harness from https://github.com/google/shaderc
to allow testing CLI tools.
New features needed for SPIRV-Tools include:
1- A new PlaceHolder subclass for spirv shaders. This place holder
calls spirv-as to convert assembly input into SPIRV bytecode. This is
required for most tools in SPIRV-Tools.
2- A minimal testing file for testing basic functionality of spirv-opt.
Add tests for all flags in spirv-opt.
1. Adds tests to check that known flags match the names that each pass
advertises.
2. Adds tests to check that -O, -Os and --legalize-hlsl schedule the
expected passes.
3. Adds more functionality to Expect classes to support regular
expression matching on stderr.
4. Add checks for integer arguments to optimization flags.
5. Fixes#1817 by modifying the parsing of integer arguments in
flags that take them.
6. Fixes -Oconfig file parsing (#1778). It reads every line of the file
into a string and then parses that string by tokenizing every group of
characters between whitespaces (using the standard cin reading
operator). This mimics shell command-line parsing, but it does not
support quoting (and I'm not planning to).
