-+ * This pass performs multiple optimizations.
-+ *
-+ * #1 propagate_moves
-+ * check if a->b->a can be moved out of a loop.
-+ *
-+ * #2 strcpy
-+ * check if a temp reg can be eliminated.
-+ *
-+ * #3 const_comp_sub
-+ * convert a compare with int constant into sub statement.
-+ *
-+ * #4 merge_add
-+ * merge adds
-+ *
-+ * #5 elim_dead_assign
-+ * eliminate some dead assignments.
-+ *
-+ * #6 shrink stack frame
-+ * remove push/pop for unused variables
-+ *
-+ * #7 rename register
-+ * rename registers without breaking register parameters, inline asm etc.
-+ *
-+ * Lessons learned:
-+ *
-+ * - do not trust existing code, better delete insns and inster a new one.
-+ * - do not modify insns, create new insns from pattern
-+ * - do not reuse registers, create new reg rtx instances

-+ * #1 propagate_moves
-+ * check if a->b->a can be moved out of a loop.
-+ *
-+ * #2 strcpy
-+ * check if a temp reg can be eliminated.
-+ *
-+ * #3 const_comp_sub
-+ * convert a compare with int constant into sub statement.
-+ *
-+ * #4 merge_add
-+ * merge adds
-+ *
-+ * #5 elim_dead_assign
-+ * eliminate some dead assignments.
-+ *
-+ * #6 shrink stack frame
-+ * remove push/pop for unused variables
-+ *
-+ * #7 rename register
-+ * rename registers without breaking register parameters, inline asm etc.
-+ *
-+ * Lessons learned:
-+ *
-+ * - do not trust existing code, better delete insns and inster a new one.
-+ * - do not modify insns, create new insns from pattern
-+ * - do not reuse registers, create new reg rtx instances
