◆ checkCapabilityRequirements()
|
static |
Checks that candidatescapability requirements are possible to be satisfied with the given isAllowedFn.
candidates is a vector of vector for capability requirements following ((Capability::A OR Capability::B) AND (Capability::C OR Capability::D)) convention.

static |
Checks that candidates extension requirements are possible to be satisfied with the given targetEnv.
candidates is a vector of vector for extension requirements following ((Extension::A OR Extension::B) AND (Extension::C OR Extension::D)) convention.

Converts a scalar type to a suitable type under the given targetEnv.

◆ convertTensorType()
|
static |
Converts a tensor type to a suitable type under the given targetEnv.
Note that this is mainly for lowering constant tensors. In SPIR-V one can create composite constants with OpConstantComposite to embed relative large constant values and use OpCompositeExtract and OpCompositeInsert to manipulate, like what we do for vectors.
