◆ RuntimeLibcallsInfo() [2/3]

◆ RuntimeLibcallsInfo() [3/3]

RuntimeLibcallsInfo::RuntimeLibcallsInfo ( const Module & M) explicit

◆ getFunctionTy()

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.

◆ lookupLibcallImplName()

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.
