Yes. This patch was in response to:
! emit_jump_insn_before (tem, loop_end);
!
! for (tem = PREV_INSN (loop_end);
! tem && GET_CODE (tem) != JUMP_INSN;
! tem = PREV_INSN (tem))
! ;
!
! if (tem)
! JUMP_LABEL (tem) = XEXP (jump_label, 0);
---
! loop_emit_jump_insn_before (tem, loop_end, XEXP (jump_label, 0));
from the first patch.
