--- Comment #9 from H.J. Lu <hjl.tools at gmail dot com> ---
With Bm constraint on SSE *mov<mode>_internal, curr_insn_transform in
lra-constraints.c generates an extra

(insn 354 353 323 8 (set (reg:V4SF 192)
        (reg:V4SF 202 [192])) 1226 {*movv4sf_internal}
     (nil))

for input:

(insn 353 322 354 8 (set (reg:V4SF 202 [192])
        (reg:V4SF 201 [192])) 1226 {*movv4sf_internal}
     (nil))
