2015-11-21 Mike Frysinger <vapier@gentoo.org>
* gencode.c (tab): Pass sd into trap calls.
* interp.c (prog_argv, callback): Delete.
(parse_and_set_memory_size): Add SIM_DESC arg.
(trap): Declare callback and prog_argv.
(sim_resume): Declare callback.
(sim_info): Change callback->printf_filtered calls to sim_io_printf.
(sim_open): Delete callback assignment. Pass sd to
parse_and_set_memory_size.
(parse_and_set_memory_size): Change callback->printf_filtered call
to sim_io_printf.
(sim_create_inferior): Delete prog_argv assignment.
(sim_do_command): Change callback->printf_filtered calls to
sim_io_printf. Pass sd to parse_and_set_memory_size.
