/* This file contains two arrays with information concerning the C_INSTR tokens:
* t_C_info C_info[]; - Describes the arguments of EM-instructions
* struct ? EM_instr[]; - Contains per entry:
* 1) The name of the C_INSTR
* 2) The type of its argument, an index in
* C_info[].
* 3) The segment for which code/data must
* be generated.
* The array is sorted on the C_INSTR-name.
*
* Furthermore there are two routines present in this file :
* set_C_instr_info( instr) - It looks 'instr' up in EM_instr[] and
* char *instr; - sets the global variables
* - 'C_instr_info' and 'segment'.
*
* arg_type( arg) - 'arg' must be a string starting with a '$'
* char *arg; - and a number. arg_type() will return the
* - type of the 'number'th argment of the current
* - C_INSTR.
* - For example, if the EM_table contains:
* C_loc ==> "pushl $1".
* then arg_type( "$1") will return ARITH.
