Thu Aug 28 12:09:15 1997 Andrew Cagney <cagney@b1.cygnus.com>
* sim-base.h (STATE_ARCHITECTURE, STATE_TARGET): Add to simulator
base type.
* sim-options.c (standard_options): Add --architecture=MACHINE and
--target=TARGET options.
(OPTION_ARCHITECTURE, OPTION_TARGET): Define.
(standard_option_handler): Handle architecture and target options.
(bfd.h): Include.
* sim-utils.c (sim_analyze_program): Pass STATE_TARGET to
bfd_openr.
(sim_analyze_program): Set prog_bfd architecture from
STATE_ARCHITECTURE if known.
