Handling Local Variables When the interpreter encounters an int or char keyword, it calls decl_local( ) to create storage for a local variable As stated earlier, no global variable declaration statement will be encountered by the interpreter once the program is executing, because only code within a function is executed Therefore, if a variable declaration statement is found, it must be for a local variable (or a parameter, which will be discussed in the next section) In structured languages, local variables are stored on a stack If the language is compiled, the system stack is generally used; however, in an interpreted mode, the stack for local variables must be maintained by the interpreter The stack for local variables is held by the array local_var_stack Each time a local variable is encountered, its name, type, and value (initially zero) are pushed onto the stack using local_push( ) The global variable lvartos indexes the stack (For reasons that will become clear, there is no corresponding ''pop" function Instead, the local variable stack is reset each time a function returns) The decl_local and local_push( ) functions are shown here:
Page 767 /* Declare a local variable */ void decl_local(void) { struct var_type i; get_token(); /* get type */
iv_type = tok; ivalue = 0; /* init to 0 */ do { /* process comma-separated list */ get_token(); /* get var name */ strcpy(ivar_name, token); local_push(i); get_token (); } while(*token == ','); if(*token != ';') sntx_err(SEMI_EXPECTED); } /* Push a local variable */ void local_push(struct var_type i) { if(lvartos > NUM_LOCAL_VARS) sntx_err(TOO_MANY_LVARS); local_var_stack[lvartos] = i; lvartos++; }
The decl_local ( ) function first reads the type of the variable or variables being declared and sets the initial value to zero Next, it enters a loop, which reads a comma-separated list of identifiers Each time through the loop, the information about each variable is pushed onto the local variable stack At the end, the final token is checked to make sure that it contains a semicolon Calling User-Defined Functions Probably the most difficult part of implementing an interpreter for C is the execution of user-defined functions Not only does the interpreter need to begin reading the source code at a new location and then return to the calling routine after the function terminates, but it must also deal with these tasks: the passing of arguments, the allocation of parameters, and the return value of the function All function calls (except the initial call to main( )) take place through the expression parser from the atom( ) function by a call to call( ) It is the call( ) function
