--- Comment #3 from ktkachov at gcc dot gnu.org ---
FWIW On 4.7.4 without LRA the ICE is:
ice.c:9:1: error: insn does not satisfy its constraints:
(insn 25 12 19 2 (set (reg:QI 2 r2)
(reg:QI 13 sp)) ice.c:8 193 {*arm_movqi_insn}
(nil))
But 4.7 is no loner maintained, so that's more of a trivia at this point
