--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So there is no confusion here.
Look at gen_ldm_seq:
The last set to base_reg is not needed.

Look at arm_gen_movmemqi, the for loop that sets i and increments i but never
uses i; The condition that is used here is in_words_to_go.

Look at arm_expand_prologue: the last setting of insn and insn is not used
after that point.

Look at thumb_pop: pushed_words is only set or incremented and never used
otherwise.

For the last one look at thumb1_emit_multi_reg_push, the last setting of
regs_to_pop is not used after that except in a comment.
