Revision history for SPIRV-Tools
v2016.6-dev 2016-09-16
- Published the C++ interface for assembling, disassembling, validation, and
optimization.
- Support SPV_KHR_shader_draw_parameters in assembler, disassembler, parser.
- Fixes issues:
#429: Validator: Allow OpTypeForwardPointer and OpTypeStruct to reference
undefined IDs
v2016.5 2016-09-16
- Support SPV_KHR_shader_ballot in assembler, disassembler, parser.
- Disassembler: Generate friendly names for built-in variables.
- Partial fixes:
#359: Add Emacs helper for automatically diassembling/assembling a SPIR-V
binary on file load/save.
- Fixes:
#414: Validator: Allow OpUndef for composite constants
#415: Validator: Phi can use its own value in some cases.
v2016.4 2016-09-01
- Relicensed under Apache 2.0
- Add optimization passes (in API and spirv-opt command)
- Fold spec constants defined with OpSpecConstantOp and
OpSpecConstantComposite to normal constants with fixed value(s).
- Fixes issues:
#318: Relicensed under Apache 2.0
v2016.3 2016-08-24
- Add target environment enums for OpenCL 2.1, OpenCL 2.2,
OpenGL 4.0, OpenGL 4.1, OpenGL 4.2, OpenGL 4.3, OpenGL 4.5.
- Add spirv-cfg, an experimental tool to dump the control flow graph
as a GraphiViz "dot" graph
- Add optimization pass: Eliminate dead constants.
- Add spirv-lesspipe.sh filter utility
- Fixes issues:
#288: Check def-use dominance rules for OpPhi (variable,parent) operands
#339: Allow OpUndef in types-constants-global-vars section, as required
by SPIR-V 1.0 Rev7, 1.1 Rev 3.
#340: Avoid race on mkdir during build
#365: Relax PointSize, ClipDistance, CullDistance capability check in all
environments not just Vulkan 1.0.
v2016.2 2016-08-05
- Validator is incomplete
- Checks ID use block is dominated by definition block
- Add optimization passes (in API and spirv-opt command)
- Strip debug info instructions
- Freeze spec constant to their default values
- Allow INotEqual as operation for OpSpecConstantOp
- Fixes bugs:
#270: validator: crash when continue construct is unreachable
#279: validator: infinite loop when analyzing some degenerate control
flow graphs
#286: validator: don't incorrectly generate def-use error for
(variable,parent) parameters to OpPhi
#290: disassembler: never generate bare % for an identifier
#295: validator: def-use dominance check should ignore unreachable uses
#276: validator: allow unreachable continue constructs
#297: validator: allow an unreachable block to branch to a reachable
merge block
v2016.1 2016-07-19
- Fix https://github.com/KhronosGroup/SPIRV-Tools/issues/261
Turn off ClipDistance and CullDistance capability checks for Vulkan.
- The disassembler can emit friendly names based on debug info (OpName
instructions), and will infer somewhat friendly names for most types.
This is turned on by default for the spirv-dis command line tool.
- Updated to support SPIR-V 1.1 rev 2
- Input StorageClass, Sampled1D capability, and SampledBuffer capability
do not require Shader capability anymore.
v2016.0 2016-07-04
- Adds v<year>.<index> versioning, with "-dev" indicating
work in progress. The intent is to more easly report
and summarize functionality when SPIRV-Tools is incorporated
in downstream projects.
- Summary of functionality (See the README.md for more):
- Supports SPIR-V 1.1 Rev 1
- Supports SPIR-V 1.0 Rev 5
- Supports GLSL std450 extended instructions 1.0 Rev 3
- Supports OpenCL extended instructions 1.0 Rev 2
- Assembler, disassembler are complete
- Supports floating point widths of 16, 32, 64 bits
- Supports integer widths up to 64 bits
- Validator is incomplete
- Checks capability requirements in most cases
- Checks module layout constraints
- Checks ID use-definition ordering constraints,
ignoring control flow
- Checks some control flow graph rules
- Optimizer is introduced, with few available transforms.
- Supported on Linux, OSX, Android, Windows
- Fixes bugs:
- #143: OpenCL pow and pown arguments
