Update the known good SPIRV-Tools commit to eventually propagate the
commit allowing the ray tracing stages in pass instrumentation to the
vulkan validation layers (validation layers depends on glslang which
depends on spirv-tools).
Including spirv and AST tests
Also increase size of TBuiltInVariable bitfields since we've now exceeded 127
and add a static_assert to make this easier to find next time it happens!
You may need to install python 3.x and also
[windows users] may need to get it in your path in front of python 2.7.x.
If you don't need the external projects (i.e., SPIRV-Tools) and don't want
to upgrade to python 3, don't create the External subdirectory and CMake
won't require python 3. (CMake has a bug that makes it find the wrong one
on a first pass if the top level does not require the version needed by
lower levels.)
Includes the following:
Add Vulkan 1.1 capability sets
Don't merge types of resources
Remove stores of undef.
Make sure the constant folder get the correct type.
Includes the following spirv-opt improvements:
Preserve inst-to-block and def-use in passes.
Add store for var initializer in inlining.
Handle types with self references.
Includes:
Fold divide and multiply by same value.
Allow ADCE to remove more instructions.
Remove dead Workgroup variables in ADCE.
Fold fclamp feeding compare.
Add pass to fold a load feeding an extract.
Remove redundant stores.
SROA: Only create symbols that are loaded.
Get ADCE to handle OpCopyMemory
Remove the limit on struct size in SROA.
Notably, this includes the following:
- Fix exponential performance of DeadInsertElim
- Constant folding of OpVectorTimesScalar
- Add Vector DCE
- Add store-store elimination to LocalSingleBlockElim
- Improve folding of OpVectorTimesScalar and OpPhi
- Fixes handling of kill and unreachable ops in inlining
Changes include:
Fix SSA rewrite for nested loops.
Add support for two new extensions:
- SPV_NV_shader_subgroup_partitioned
- SPV_EXT_descriptor_indexing
Legalize OpImageTexelPointer
Copy propagate arrays
Contains the following improvements:
Fixes 1341: Atomics (and other instructions with side-effects) removed.
Add folding for redundant add/sub/mul/div/mix operations
Add constant folding rules for floating-point comparison
Add folding of redundant OpSelect insns
Add folding of OpCompositeExtract and OpConstantComposite
