So if I have emit_move_insn not to produce:
(insn 10 9 11 3 t1.c:10 (set (subreg:SF (reg/v:SI 119 [ c ]) 0)
(reg:SF 123)) -1 (nil))
but instead:
(insn 10 9 11 3 t1.c:10 (set (reg/v:SI 119 [ c ])
(subreg:SI (reg:SF 123) 0)) -1 (nil))
I could not get the (subreg:SI (reg:SF 123) 0) propgated into
(insn 11 10 16 3 t1.c:11 (set (mem:SI (reg/v/f:DI 121 [ b ]) [3 S4 A32])
(reg/v:SI 119 [ c ])) -1 (nil))
I have not figured out why yet. Once that is done, we can have simplify_set in
combine change the modes of the mem.
