Function Documentation

◆ getConvergenceRegions()

ConvergenceRegionInfo llvm::SPIRV::getConvergenceRegions ( Function F,
DominatorTree DT,
LoopInfo LI 
)

◆ getConvergenceToken() [1/2]

std::optional< IntrinsicInst * > llvm::SPIRV::getConvergenceToken ( BasicBlock BB)

◆ getConvergenceToken() [2/2]

std::optional< const IntrinsicInst * > llvm::SPIRV::getConvergenceToken ( const BasicBlock BB)

Definition at line 119 of file SPIRVConvergenceRegionAnalysis.cpp.

◆ 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.

◆ parseBuiltinCallArgumentBaseType()

Type * llvm::SPIRV::parseBuiltinCallArgumentBaseType ( const StringRef  DemangledCall,
unsigned  ArgIdx,
LLVMContext Ctx 
)

Parses the provided ArgIdx argument base type in the DemangledCall skeleton.

A base type is either a basic type (e.g. i32 for int), pointer element type (e.g. i8 for char*), or builtin type (TargetExtType).

Returns
LLVM Type or nullptr if unrecognized

DemangledCall is the skeleton of the lowered builtin function call. ArgIdx is the index of the argument to parse.

◆ parseBuiltinTypeNameToTargetExtType()

TargetExtType * llvm::SPIRV::parseBuiltinTypeNameToTargetExtType ( std::string  TypeName,
LLVMContext Context 
)

Translates a string representing a SPIR-V or OpenCL builtin type to a TargetExtType that can be further lowered with lowerBuiltinType().

Returns
A TargetExtType representing the builtin SPIR-V type.

TypeName is the full string representation of the SPIR-V or OpenCL builtin type.
