Function dmd.escape.escapeByValue

e is an expression to be returned by value, and that value contains pointers. Walk e to determine which variables are possibly being returned by value, such as: int* function(int* p) { return p; } If e is a form of &p, determine which variables have content which is being returned as ref, such as: int* function(int i) { return &i; } Multiple variables can be inserted, because of expressions like this: int function(bool b, int i, int* p) { return b ? &i : p; }

void escapeByValue (
  Expression e,
  EscapeByResults* er,
  bool live = false,
  bool retRefTransition = false

No side effects.


e expression to be returned by value
er where to place collected data
live if @live semantics apply, i.e. expressions p, *p, **p, etc., all return p.
retRefTransition if e is returned through a return ref scope function call
