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.
|
|
|
|

|
|

|
|
- Validator is incomplete
|
|
- Checks capability requirements in most cases
|
|
- Checks module layout constraints
|
|
- Checks ID use-definition ordering constraints,
