The problem seems to be that during combine simplify-rtx.c "simplifies":
(sign_extend:DI (ior:SI (lshiftrt:SI (reg:SI 125)
(const_int 31 [0x1f]))
(subreg/s:SI (reg:DI 134 [ iftmp.1 ]) 4)))
into:
(ior:DI (and:DI (lshiftrt:DI (subreg:DI (reg:SI 125) 0)
(const_int 31 [0x1f]))
(const_int 3 [0x3]))
(reg:DI 134 [ iftmp.1 ]))
It is not 2 bits but one bit that should be ored into.
