gimplify.c - missing tree codes

[Steve Teale]

In 4.3.4,the switch in function gimplify_expr(...) included:


	case STATIC_CHAIN_EXPR:
	  /* The argument is used as information only.  No need to
	     gimplify */
	case STATIC_CHAIN_DECL:  
	  ret = GS_ALL_DONE;
	  break;

4.4.3 does not mention these codes, so any front end that generates them
fails at a later catch-all with an Internal compiler error.

What was the rationale for removing them? Is it a big deal to put them
back?

Thanks
Steve
