I'd still need to do the resolve_reg_p check, otherwise if it is e.g. a

Hi!
On the following testcase, we have
(insn 10 7 11 2 (set (reg/v:TI 106 [ h ])
(rotate:TI (reg/v:TI 106 [ h ])
(const_int 64 [0x40]))) "pr114211.c":8:5 1042 {rotl64ti2_doubleword}
(nil))
before subreg1 and the pass decides to use
(reg:DI 127 [ h ]) / (reg:DI 128 [ h+8
