I've added a movti expander to sh.md, and found a regression for -m4 -ml on simd-1.c with optimization options -O1, -O2, -O3 and -Os . I've foun that a output reload address was being overwritten by a secondary output reload. The secondary output reload had RELOAD_FOR_OUTPUT_ADDRESS, and the address reload had RELOAD_FOR_OUTADDR_ADDRESS, both for the same operand. In the absence of a seond RELOAD_FOR_OUTPUT_ADDRESS reload, these types are not supposed to conflict. The output address reload should have used RELOAD_FOR_OUTPUT_ADDRESS.
