Thanks for checking, Richard!


For those wondering, like me, where ptr_mode is defined: gcc/machmode.h has:
  extern enum machine_mode ptr_mode;

The the function itself is (tree.c):

/* Construct, lay out and return the type of pointers to TO_TYPE with
   mode MODE.  If CAN_ALIAS_ALL is TRUE, indicate this type can
   reference all of memory. If such a type has already been
   constructed, reuse it.  */

tree
build_pointer_type_for_mode (tree to_type, enum machine_mode mode,
                             bool can_alias_all)
