v2017.1 2017-11-23
|
|
- Update README with details on the public_spirv_tools_dev@khronos.org mailing list.
|
|
- General:
|
|
- Automatically deploy built artifacts to GitHub Releases
|
|
- Add a Linker (module combiner). Under development.
|
|
- Add Android.mk for Android NDK builds.
|
|
- Add the 'effcee' library as an optional dependency for use in tests.
|
|
Eventually it will be a required dependency, once downstream projects have
|
|
a chance to adjust. Requires 're2' library.
|
|
- Avoid static-duration variables of class type (with constructors).
|
|
- Hack around bugs in gcc-4.8.1 template handling
|
|
- Faster opcode lookup
|
|
- Validator:
|
|
- Recognize extensions listed on SPIR-V registry,
|
|
through #25 SPV_AMD_shader_fragment_mask
|
|
- Validator issues an info message when it sees an unrecognized extension.
|
|
- Type check basic arithmetic operations
|
|
- Type check carry/extended arithmetic operations
|
|
- Type check vector arithmetic operations
|
|
- Type check Relational and Logical instructions

|
|
section.
|
|
- Checks the right kind of return is called for each function (void or non-void).
|
|
- Add option to relax type check when storing structs (--relax-store-struct)
|
|
- Optimizer:
|
|
- Refactoring internal representation of the module, including:
|
|
- IRContext: owns a module and manages analyses
|
|
- Instructions are owned by intrusive lists, and have unique IDs
|
|
- BasicBlock owns its instruction list.
|
|
- DefUseManager: change representation of uses, for faster processing
|
|
on large modules.
|
|
- Add high level recipes: -O, -Os, and -Oconfig
|
|
Recipes for -O and -Os are under development.
|
|
- Add eliminate-dead-function transform
|
|
- Add strength reduction transform: For now, convert multiply by power of 2
|
|
to a bit shift.
|
|
- Add CFG cleanup transform
|
|
- Add removal of dead module-scope variables
|
|
- Add merge-return transform for modules without structured control flow
|
|
- Add redundancy elimination within a basic block (local value numbering)
|
|
- Extract-insert elimination:
|
|
- Recognize the case where the first instruction in the sequence is an
|
|
OpCompositeConstruct or OpConstantComposite
|
|
- Handle some cases of nested structs
|
|
- Dead branch elimination now can eliminate entire selection constructs
|
|
when all arms are dead.
|
|
- Compressing codec:
|
|
- Updated algorithm to 1.01, 1.02, 1.03
|
|
- Not built by default. Use -DSPIRV_BUILD_COMPRESSION=ON to build.
|
|
- Codec can be parameterized by a customized model.
