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)
