/* This is the main driving routine of the optimizer.
 * It first processes the flags given as argument;
 * for every flag it does not recognize itself, it
 * calls 'proc_flag'; as soon as the -M flag is seen,
 * it opens the machine descriptor file and
 * reads phase-independend information (notably the
 * wordsize and pointersize of the target machine);
 * next it calls 'phase_machinit' with this file as
 * parameter. Subsequently it calls 'initialize'.
 * Finally, all procedures are read, one at a time,
 * and 'optimize' is called with the current procedure
 * as parameter.
