Sat Jan 27 07:59:25 1996 Richard Kenner (kenner@vlsi1.ultra.nyu.edu)
* tree.h (enum built_in_function): Add BUILT_IN_{SET,LONG}JMP. * expr.c: Include hard-reg-set.h. (arg_pointer_save_area): New declaration. (expand_builtin, case BUILT_IN_{SET,LONG}JMP): New cases. * Makefile.in (expr.o): Includes hard-reg-set.h. * c-decl.c (init_decl_processing): Add definitions for __builtin_setjmp and __builtin_longjmp. * cccp.c (initialize_builtins): Add def of __HAVE_BUILTIN_SETJMP__.
* expr.c (expand_expr, case COMPONENT_REF): Pass EXPAND_INITIALIZER to recursive call.
IOW - old; the last branch lacking it is 2.7.2.* Both 2.8 and egcs (and thus 2.95 and everything subsequent) have it.
