Eliminate the checked cast from get_call_reg_set_usage
gcc/ChangeLog
2014-09-05 David Malcolm <dmalcolm@redhat.com>
* caller-save.c (setup_save_areas): Strengthen local "insn" from
rtx to rtx_insn *.
* final.c (get_call_reg_set_usage): Likewise for first param,
eliminating a checked cast.
* regs.h (get_call_reg_set_usage): Likewise for first param.
* resource.c (mark_set_resources): Introduce local rtx_call_insn *
"call_insn" for the case of a MARK_SRC_DEST_CALL via a checked
cast, replacing references to "x" with "call_insn" where
appropriate.
(mark_target_live_regs): Strengthen local "real_insn" from rtx to
rtx_insn *, adding a checked cast.
