rs6000.h (LEGITIMATE_LO_SUM_ADDRESS_P): Complex LO_SUM addresses less than word size are not legitimate...
* config/rs6000/rs6000.h (LEGITIMATE_LO_SUM_ADDRESS_P): Complex
LO_SUM addresses less than word size are not legitimate,
because they lead to invalid SUBREGs.
* config/rs6000/rs6000.c (rs6000_legitimize_address): Likewise.
