[HLSL] Diagnostics for semantic annotations #87393

Open llvm-beanz opened 3 months ago

llvm-beanz commented 3 months ago

Description

This issue tracks all-up diagnostics for semantic annotations. We need to identify all the parts of this.

For example:

In HLSL there are certain combinations of semantics that are valid for inputs and outputs of shaders as defined by the shader stage. @bob80905 began writing a proposal for how we can perform this analysis and verification during semantic analysis: https://github.com/microsoft/hlsl-specs/pull/156

Acceptance Criteria

Implement robust diagnostic for combinations of semantics on inputs and outputs as defined in the specification above.

See this DXC bug that has some cases that should be considered here: https://github.com/microsoft/DirectXShaderCompiler/issues/3508
