Revision history for SPIRV-Tools
|
||||
|
||||
v2017.3-dev 2017-12-15
|
||||
- Start v2017.3-dev
|
||||
v2017.3 2018-01-12
|
||||
- General:
|
||||
- Generate a SPIRV-Tools.pc file for pkg-config
|
||||
- Support DebugInfo extended instruction set, targeted at OpenCL environments.
|
||||
See the SPIR-V Registry.
|
||||
- Generate a SPIRV-Tools.pc file for pkg-config.
|
||||
- Optimizer:
|
||||
- Add Private-to-Function variable conversion for modules with logical
|
||||
addressing
|
||||
- Add --legalize-hlsl option to run transforms used to transform intermediate
|
||||
code generated by HLSL to SPIR-V for Vulkan compilers. Those compilers
|
||||
normally run these transforms automatically. This option is used for developing
|
||||
those transforms.
|
||||
- Progress for legalization of code generated from HLSL (issue #1118):
|
||||
- Add --legalize-hlsl option to run transforms used to transform intermediate
|
||||
code generated by HLSL to SPIR-V for Vulkan compilers. Those compilers
|
||||
normally run these transforms automatically. This option is used for developing
|
||||
those transforms.
|
||||
- Add Private-to-Function variable conversion for modules with logical
|
||||
addressing.
|
||||
- Add --ccp: SSA Conditional Constant Propagation (CCP)
|
||||
- Add --print-all to show disassembly for each optimization pass.
|
||||
- Internal: Add loop descriptors and post-order tree iterator.
|
||||
- Generalized dead branch elimination
|
||||
- Aggressive dead code elimination (ADCE) now removes dead functions and
|
||||
module-scope variables.
|
||||
- Vector extract/insert elimination now optimizes through some cases of
|
||||
VectorShuffle, and GLSL.std.450 Mix extended instruction.
|
||||
- Validator:
|
||||
- Add validation for GLSL.std.450 extended instruction set.
|
||||
- Check out of bounds composite accesses, where that's statically computable.
|
||||
Fixes #1112.
|
||||
- Check upper bits of literal numbers that aren't a multiple of 32-bits wide.
|
||||
- More validation of primitive instructions
|
||||
- Add optional "relaxed" checking logical addressing mode to permit some
|
||||
cases of pointer-to-pointer. Contributes to HLSL legalization (issue #1118).
|
||||
- Fixes:
|
||||
#1100: Validator: Image operand Sample can be used with OpImageSparseFetch,
|
||||
OpImageSparseRead
|
||||
OpImageSparseRead.
|
||||
#1108: Remove duplicates transform was incorrectly removing non-duplicate
|
||||
decorations.
|
||||
#1111: Optimizer's type manager could reference deleted memory
|
||||
#1111: Optimizer's type manager could reference deleted memory.
|
||||
#1112: Fix decoration equality check, e.g. it is now symmetric.
|
||||
#1129: Validator now disallows Dim=SupbassData for OpImageSparseRead.
|
||||
#1143: Fix CCP: Was generating incorrect code for loops.
|
||||
#1153: Fix CCP crash.
|
||||
#1154: Optimizer's internal instruction-to-block mappings were sometimes
|
||||
inconsistent.
|
||||
#1159: Fix CCP infinite loop.
|
||||
#1168: Fix dead branch elimination intermittently generating incorrect code.
|
||||
Fixes https://github.com/KhronosGroup/glslang/issues/1205
|
||||
#1186: Fix validation of PackDouble2x32 and UnpackDouble2x32
