                    Steven Bosscher  <steven@gcc.gnu.org>

        * Makefile.in (cfgrtl.o): Add $(INSN_ATTR_H).
        * cfgrtl.c: Include insn-attr.h.
        (rest_of_pass_free_cfg): New function.
        (pass_free_cfg): Use rest_of_pass_free_cfg as execute function.

                    Eric Botcazou  <ebotcazou@adacore.com>

        * resource.c (find_basic_block): Use BLOCK_FOR_INSN to look up
        a label's basic block.
        (mark_target_live_regs): Tidy and rework obsolete comments.
        Change back DF problem to LIVE.  If a label starts a basic block,
        assume that all registers that used to be live then still are.
        (init_resource_info): If a label starts a basic block, set its
        BLOCK_FOR_INSN accordingly.
        (free_resource_info): Undo the setting of BLOCK_FOR_INSN.
