demangledArgTypesMatchIR()

bool llvm::SPIRV::demangledArgTypesMatchIR ( const SPIRV::IncomingCall * Call, StringRef DemangledCall, SPIRVGlobalRegistry * GR, LLVMContext & Ctx, const CallBase & CB )

static

Checks that scalar/vector numeric arguments of Call match the types implied by their mangling in DemangledCall.

Pointers and opaque builtin types (images, samplers, pipes, etc.) are not validated here, as mangling does not enforce their exact spelling.

Returns

false if a numeric argument's SPIR-V type disagrees with the type implied by the mangled name, true otherwise.

Handles the translation of the provided special opaque/builtin type Type to SPIR-V type.

Generates the corresponding machine instructions for the target type or gets the already existing OpType<...> register from the global registry GR.

Returns

A machine instruction representing the OpType<...> SPIR-V type.

Type is the special opaque/builtin type to be lowered.
