◆ getFunctionTy()

std::pair< FunctionType *, AttributeList > RuntimeLibcallsInfo::getFunctionTy ( LLVMContext & Ctx,
const Triple & TT,
const DataLayout & DL,
RTLIB::LibcallImpl LibcallImpl ) const
Returns
the function type and attributes for the LibcallImpl, depending on the target TT. If the function has incomplete type information, return nullptr for the function type.

◆ hasVectorMaskArgument()

bool RuntimeLibcallsInfo::hasVectorMaskArgument ( RTLIB::LibcallImpl Impl)

◆ lookupLibcallImplName()

LLVM_ABI iota_range< RTLIB::LibcallImpl > llvm::RTLIB::RuntimeLibcallsInfo::lookupLibcallImplName ( StringRef Name)
inlinestatic

Check if a function name is a recognized runtime call of any kind.

This does not consider if this call is available for any current compilation, just that it is a known call somewhere. This returns the set of all LibcallImpls which match the name; multiple implementations with the same name may exist but differ in interpretation based on the target context.
