LOC(X) returns the address of X as an integer: https://gcc.gnu.org/onlinedocs/gfortran/LOC.html Before: (gdb) p LOC(r) No symbol "LOC" in current context. After: (gdb) p LOC(r) $1 = 0xffffdf48 gdb/ChangeLog: 2021-03-09 Felix Willgerodt <felix.willgerodt@intel.com> * f-exp.h (eval_op_f_loc): Declare. (expr::fortran_loc_operation): New typedef. * f-exp.y (exp): Handle UNOP_FORTRAN_LOC after parsing an UNOP_INTRINSIC. (f77_keywords): Add LOC keyword. * f-lang.c (eval_op_f_loc): New function. * std-operator.def (UNOP_FORTRAN_LOC): New operator. gdb/testsuite/ChangeLog: 2020-03-09 Felix Willgerodt <felix.willgerodt@intel.com> * gdb.fortran/intrinsics.exp: Add LOC tests.
