Targets should implement this method to assign a section to globals with an explicit section specfied.
The implementation of this method can assume that GO->hasSection() is true.

◆ getFunctionEntryPointSymbol()
|
overridevirtual |
If supported, return the function entry point symbol.
Otherwise, returns nullptr. Func must be a function or an alias which has a function as base object.
