OK, thanks, I see the problem.
Roger, if you haven't already plugged it, the very same hole is present in the
STRICT_LOW_PART case too. For Jan's testcase:
(insn 10 35 12 2 (set (zero_extract:SI (subreg:SI (reg/v:DI 58 [ a ]) 4)
(const_int 8 [0x8])
(const_int 8 [0x8]))
(const_int 1 [0x1])) 53 {movsi_insv_1} (insn_list:REG_DEP_TRUE 35
(nil))
(nil))
(insn 12 10 14 2 (set (subreg:SI (reg/v:DI 58 [ a ]) 0)
(const_int 1 [0x1])) 34 {*movsi_1} (insn_list:REG_DEP_TRUE 10 (nil))
(nil))
(insn 14 12 16 2 (set (strict_low_part (subreg:QI (reg/v:DI 58 [ a ]) 4))
(const_int 1 [0x1])) 46 {*movstrictqi_1} (insn_list:REG_DEP_TRUE 12
(nil))
(nil))
