As the following testcase shows, get_reload_reg could sometimes return
a reused reg in a wrong mode. If curr_insn_input_reloads[i].input
and original have VOIDmode, they could compare equal (same integer
constant), yet mode might be different from

Hi!
As the following testcase shows, get_reload_reg could sometimes return
a reused reg in a wrong mode. If curr_insn_input_reloads[i].input
and original have VOIDmode, they could compare equal (same integer
constant), yet mode might be different from
GET_MODE (curr_insn_input_reloads[i].reg).
