- Support DebugInfo extended instruction set, targeted at OpenCL environments.
|
|
|

|
See the SPIR-V Registry.
|
|
|
|

- Optimizer:
|
2018-01-12 18:32:04 +00:00
|
|
|
- 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.

|
|
|
|
|

|
|
|
|
- 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.

|
|
|
|
Fixes #1112.
|
2017-12-19 22:50:01 +00:00
|
|

|
|
|
|
|
- More validation of primitive instructions
|
2018-01-12 18:32:04 +00:00

cases of pointer-to-pointer. Contributes to HLSL legalization (issue #1118).
