v2026.4 2026-09-09
- Optimizer
- Add pass to convert typed pointers to untyped pointers (`--convert-to-
untyped`)
- Support optimizing shaders using SPV_KHR_opacity_micromap across dead-code
elimination and local passes
- Add folding rule to dissolve OpCopyLogical of OpCompositeConstruct in
simplification pass
- Harden optimizer passes against ID overflow (#6851, #6852, #6857, #6858,
#6863)
- Filter duplicate decorations during module serialization to binary
- Correctness fixes for vector constant folding size and OpSelect folding
pre-SPIR-V 1.4 (#6798, #6827)
- Stability fixes for IRContext analysis handling, debug info stripping, and
eliminate dead functions (#6765, #6797, #6799)
- Validator
- Support and validate SPV_EXT_cooperative_matrix_maintenance1
- Support and validate SPV_QCOM_image_processing3 and OpImageGatherQCOM
- Add validation for NonSemantic.DebugPrintf extended instruction set
- Validate OpAbortKHR explicit layout message type and require scalar
packing (#6854, #6859)
- Tighten relaxed block layout alignments and add explicit alignment VUIDs
(#6819, #6853)
- Validate Offset decoration on Input/Output storage classes and add VUID
12509 (#6835, #6855)
- Allow OpExtInstWithForwardRefsKHR in generic non-semantic instruction sets
- Restrict Workgroup execution scope to OpGroupNonUniformRotateKHR for non-
uniform group operations
- Validate OpControlBarrierArriveEXT execution and memory scopes
- Allow Generic pointer casts to and from CodeSectionINTEL storage class
- Allow BFloat16 and FP8 result types in OpExtInst
- Validate OpSourceContinued order following OpSource
- Correctness fixes for >64-bit integer constant evaluation and
AliasScopeINTELMask/NoAliasINTELMask operand counting (#6816, #6791,
#6865)
- Validate ArrayStride on OpConstantDataKHR result types
- Add validation for UTFEncodedKHR decoration on array types
- Validate that OpAbortKHR Message Type is a concrete type
- Linker
- Detect duplicate exported definitions without imports to prevent ODR
violations
- Assembler/Disassembler
- Initialize parsed operand floating-point encoding to ensure deterministic
disassembly of literal floats
