ERRTYPE says whether it is argument passing, assignment,
initialization or return.
- LOCATION is the location of the assignment, EXPR_LOC is the location of
- the RHS or, for a function, location of an argument.
+ In the following example, '~' denotes where EXPR_LOC and '^' where
+ LOCATION point to:
+
+ f (var); [ic_argpass]
+ ^ ~~~
+ x = var; [ic_assign]
+ ^ ~~~;
+ int x = var; [ic_init]
+ ^^^
+ return x; [ic_return]
+ ^
+
FUNCTION is a tree for the function being called.
PARMNUM is the number of the argument, for printing in error messages. */
