Function Documentation

◆ lowerBuiltin() [1/2]

std::optional< bool > llvm::SPIRV::lowerBuiltin ( const StringRef  DemangledCall,
InstructionSet::InstructionSet  Set,
MachineIRBuilder MIRBuilder,
const Register  OrigRet,
const Type OrigRetTy,
const SmallVectorImpl< Register > &  Args,
SPIRVGlobalRegistry GR 
)

Lowers a builtin funtion call using the provided DemangledCall skeleton and external instruction Set.

Returns
the lowering success status if the called function is a recognized builtin, std::nullopt otherwise.

DemangledCall is the skeleton of the lowered builtin function call. Set is the external instruction set containing the given builtin. OrigRet is the single original virtual return register if defined, Register(0) otherwise. OrigRetTy is the type of the OrigRet. Args are the arguments of the lowered builtin call.

◆ lowerBuiltin() [2/2]

std::optional< bool > llvm::SPIRV::lowerBuiltin ( const StringRef  DemangledCall,
SPIRV::InstructionSet::InstructionSet  Set,
MachineIRBuilder MIRBuilder,
const Register  OrigRet,
const Type OrigRetTy,
const SmallVectorImpl< Register > &  Args,
SPIRVGlobalRegistry GR 
)

◆ lowerBuiltinType() [1/2]

SPIRVType * llvm::SPIRV::lowerBuiltinType ( const Type OpaqueType,
SPIRV::AccessQualifier::AccessQualifier  AccessQual,
MachineIRBuilder MIRBuilder,
SPIRVGlobalRegistry GR 
)

◆ lowerBuiltinType() [2/2]

SPIRVType * llvm::SPIRV::lowerBuiltinType ( const Type Type,
AccessQualifier::AccessQualifier  AccessQual,
MachineIRBuilder MIRBuilder,
SPIRVGlobalRegistry GR 
)

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.

◆ parseBuiltinTypeNameToTargetExtType()

const TargetExtType * llvm::SPIRV::parseBuiltinTypeNameToTargetExtType ( std::string  TypeName,
MachineIRBuilder MIRBuilder 
)
