gdb/fortran: Additional builtin procedures
Add some additional builtin procedures for Fortran, these are MOD, CEILING, FLOOR, MODULO, and CMPLX. gdb/ChangeLog: * f-exp.y (BINOP_INTRINSIC): New token. (exp): New parser rule handling BINOP_INTRINSIC. (f77_keywords): Add new builtin procedures. * f-lang.c (evaluate_subexp_f): Handle BINOP_MOD, UNOP_FORTRAN_CEILING, UNOP_FORTRAN_FLOOR, BINOP_FORTRAN_MODULO, BINOP_FORTRAN_CMPLX. (operator_length_f): Handle UNOP_FORTRAN_CEILING, UNOP_FORTRAN_FLOOR, BINOP_FORTRAN_MODULO, BINOP_FORTRAN_CMPLX. (print_unop_subexp_f): New function. (print_binop_subexp_f): New function. (print_subexp_f): Handle UNOP_FORTRAN_CEILING, UNOP_FORTRAN_FLOOR, BINOP_FORTRAN_MODULO, BINOP_FORTRAN_CMPLX. (dump_subexp_body_f): Likewise. (operator_check_f): Likewise. * fortran-operator.def: Add UNOP_FORTRAN_CEILING, UNOP_FORTRAN_FLOOR, BINOP_FORTRAN_MODULO, BINOP_FORTRAN_CMPLX gdb/testsuite/ChangeLog: * gdb.fortran/intrinsics.exp: Extend to cover MOD, CEILING, FLOOR, MODULO, CMPLX.
