v2018.1-dev 2018-02-02
- General:
- Support Visual Studio 2013 again. (Continue support for VS 2015 and VS 2017.)
- Support building SPIRV-Tools as a shared library.
- Improve the HLSL legalization optimization recipe. #1311
- Optimizer:
- Improve folding
- General speedups.
- Improve folding, including coverage for floating point and OpSelect.
- Add loop-invariant code motion pass.
- Add loop-unrolling pass, for honouring unroll hits.
- Add loop-unswitch pass.
- Add instruction simplification pass.
- Aggressive dead code elimination: Understands capability hierarchy when finding
instructions it can eliminate (combinators). (PR #1268)
- CCP can now fold floating point arithmetic. #1311
- Validator:
- Validate barrier instructions.
- Check Vulkan-specific rules for atomics.
- Fixes:
- #1265: Optimizer: Fix use-after free bug in if-conversion. (Fix object lifecycle bug
in type manager.)
- #1282: Fix new warnings found by GCC 8.0.1.
- #1285: Optimizer: Fix random failures during inlining. (Dangling references in DefUseManager)
- #1295: Optimizer: Fix incorrect handling of Phi nodes in CCP.
- #1300: Fix CCP: avoid bad CCP transitions and unsettled values.
- #1304: Avoid static-duration variables of class type (with constructors).
- #1323: Fix folding of an insert composite feeding a composite extract.
- #1339: Fix CCP: Handle OpConstantNull boolean values as conditions.
- #1341: DCEInst: Keep atomic instructions (and some others with side effects).
