[mlir][spirv] Add support for SwitchOp (#168713)

2025-11-20T15:19:10+00:00

The dialect implementation mostly copies the one of `cf.switch`, but
aligns naming to the SPIR-V spec.

[mlir][spirv] Ensure function declarations precede definitions (#164956)

2025-10-27T09:28:50+00:00

SPIR-V spec requires that any calls to external functions are preceded
by declarations of those external functions. To simplify the
implementation, we sort functions in the serializer using a stronger
condition: any functions declarations are moved before any functions
definitions - this ensures that external functions are always declared
before being used.

[mlir][spirv] Add support for SPV_ARM_graph extension - part 2 (#156665)

2025-09-12T13:51:35+00:00

This is the second patch to add support for the `SPV_ARM_graph` SPIR-V
extension to MLIR’s SPIR-V dialect. The extension introduces a new
`Graph` abstraction for expressing dataflow computations over full
resources.

The part 2 implementation includes:

- Serialization and deserialization support for:
- `OpGraphARM`, `OpGraphInputARM`, `OpGraphSetOutputARM`,
`OpGraphEndARM`
  - `OpGraphEntryPointARM`, `OpGraphConstantARM`, `OpTypeGraphARM`
- Tests covering binary round-tripping.

Graphs currently support only `SPV_ARM_tensors`, but are designed to
generalize to other resource types, such as images.

If serialization option `emitDebugInfo` is enabled, then it is required
to serialize `SPV_KHR_non_semantic_info` extension provided that it is
available in the target environment.
