* sim_calls.c (sim_create_inferior): Assert that psim_write_register succeeded. (sim_fetch_register, sim_store_register): Make "regname" constant. Delete Altivec hack. Return result from psim_read_register / psim_write_register. * psim.h (psim_read_register, psim_write_register): Change return type to int. Update comments. * psim.c: Update copyright. (psim_stack): Assert that the psim_read_register worked. (psim_read_register, psim_read_register): Return the register's size. Allocate the cooked buffer dynamically. * hw_register.c: Update copyright. (do_register_init): Check that psim_write_register succeeded. * hw_init.c: Update copyright. (create_ppc_elf_stack_frame, create_ppc_aix_stack_frame): Assert that the register transfer worked.
