lookupLibcallImplName()

static 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.
