Limit the MEMSET (setmemsi pattern) and MEMCPY (movmemsi pattern) instructions to 0-511 bytes. There is a hardware limitation on large MEMSET, MEMCPY operations that the library versions of memset() and memcpy() deal with. 2015-09-29 James Bowman <james.bowman@ftdichip.com> * config/ft32/predicates.md (ft32_imm_operand): New predicate. * config/ft32/ft32.md (movmemsi, setmemsi): Use ft32_imm_operand predicate, disallow register for operand 2.
