Add support for the 'SIZE' keyword to the Fortran expression parser. This returns the number of elements either in an entire array (passing a single argument to SIZE), or in a particular dimension of an array (passing two arguments to SIZE). At this point I have not added support for the optional third argument to SIZE, which controls the exact integer type of the result. gdb/ChangeLog: * f-exp.y (eval_op_f_array_size): Declare 1 and 2 argument forms of this function. (expr::fortran_array_size_1arg): New type. (expr::fortran_array_size_2arg): Likewise. * f-exp.y (exp): Handle FORTRAN_ARRAY_SIZE after parsing UNOP_OR_BINOP_INTRINSIC. (f77_keywords): Add "size" keyword. * f-lang.c (fortran_array_size): New function. (eval_op_f_array_size): New function, has a 1 arg and 2 arg form. * std-operator.def (FORTRAN_ARRAY_SIZE): New operator. gdb/testsuite/ChangeLog: * gdb.fortran/size.exp: New file. * gdb.fortran/size.f90: New file.
