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).
