Detailed Description

Handle function pointer.

Constructor & Destructor Documentation

◆ BTFTypeFuncProto()

BTFTypeFuncProto::BTFTypeFuncProto ( const DISubroutineType STy,
uint32_t  VLen,
const std::unordered_map< uint32_t, StringRef > &  FuncArgNames 
)

The Func kind represents both subprogram and pointee of function pointers.

If the FuncName is empty, it represents a pointee of function pointer. Otherwise, it represents a subprogram. The func arg names are empty for pointee of function pointer case, and are valid names for subprogram.
