Add CHANGES file with high level software history Add a high level version number for SPIRV-Tools, beginning with v2016.0-dev. The README describes the format of the version number. The high level version number is extracted from the CHANGES file. That works around: - stale-bait for when we don't add tags to the repository - our inability to add tags to the repository Option --version causes spirv-as, spirv-dis, and spirv-val to show the high level version number. Add spvSoftwareVersionString to return the C-string for the high level version number. Add spvSoftwareVersionDetailsString() so that clients can get more information if they want to. Also allows us to clean up the uses in the tool executables files, so now only one file includes build-version.inc. Move the update-build-version logic to the only CMakeLists file that needs it. The update build version script takes a new argument to name the output file.

Revision history for SPIRV-Tools
Start v2016.2.
2016-07-19 19:04:43 +00:00
v2016.2-dev 2016-07-19
- Start v2016.2
Check definitions appear in dominator of use Also address use and def of ID in same instruction
2016-07-13 22:57:52 +00:00
- Validator is incomplete
- Checks ID use block is dominated by definition block
Fix infinite loop in dominance calculation. Ensure the dominance calculation visits all nodes in the CFG. The successor list of the pseudo-entry node is augmented with a single node in each cycle that otherwise would not be visited. Similarly, the predecssors list of the pseduo-exit node is augmented with the a single node in each cycle that otherwise would not be visited. Pulls DepthFirstSearch out so it's accessible outside of the dominator calculation. Fixes https://github.com/KhronosGroup/SPIRV-Tools/issues/279
2016-07-27 21:02:22 +00:00
- Add optimization passes (in API and spirv-opt command)
Freeze spec constants to their default values Add a pass to freeze spec constants to their default values. This pass does not fold the frozen spec constants and does not handle SpecConstantOp instructions and SpecConstantComposite instructions.
2016-07-26 16:11:03 +00:00
- Strip debug info instructions
- Freeze spec constant to their default values
Update CHANGES to reflect INotEqual update
2016-08-02 21:48:16 +00:00
- Allow INotEqual as opertion for OpSpecConstantOp

2016-07-27 21:02:22 +00:00
- Fixes bugs:
#270: validator: crash when continue construct is unreachable
#279: validator: infinite loop when analyzing some degenerate control
flow graphs
Never generate % for a friendly disassembled Id Fixes https://github.com/KhronosGroup/SPIRV-Tools/issues/290
2016-08-02 15:59:10 +00:00
#290: disassembler: never generate bare % for an identifier
Start v2016.2.
2016-07-19 19:04:43 +00:00
Finalize v2016.1.
2016-07-19 19:03:52 +00:00
v2016.1 2016-07-19
Turn off ClipDistance CullDistance cap checks for Vulkan Turn them off until resolution of the debate over how they should be checked. Fixes https://github.com/KhronosGroup/SPIRV-Tools/issues/261
2016-07-07 21:03:22 +00:00
- Fix https://github.com/KhronosGroup/SPIRV-Tools/issues/261
Turn off ClipDistance and CullDistance capability checks for Vulkan.
Disassembling: map IDs to friendly names. Add a FriendlyNameMapper to deduce friendly names for IDs based on OpName, type structure, etc.
2016-07-08 18:29:52 +00:00
- 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.
Finalize v2016.1.
2016-07-19 19:03:52 +00:00
- Updated to support SPIR-V 1.1 rev 2
- Input StorageClass, Sampled1D capability, and SampledBuffer capability
do not require Shader capability anymore.
Start v2016.1-dev
2016-07-04 19:13:08 +00:00
Finalize v2016.0
2016-06-02 19:29:13 +00:00
v2016.0 2016-07-04

2016-04-22 00:50:11 +00:00
- 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
Finalize v2016.0
2016-06-02 19:29:13 +00:00
- 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.
