Tue May 6 06:14:01 1997 Mike Meissner <meissner@cygnus.com>
* sim-trace.c (toplevel): Include bfd.h.
(trace_options): Note that --trace-linenum also turns on
--trace-insn.
(trace_option_handler): If --trace-linenum, also turn on
--trace-insn.
(trace_one_insn): New function to trace an instruction. Support
--trace-linenum.
* sim-trace.h (TRACE_LINENUM_P): Define macro.
(trace_one_insn): Declare function.
Mon May 5 14:08:34 1997 Mike Meissner <meissner@cygnus.com>
* sim-trace.h (__attribute__): Define as nothing if not GNU C or

Tue May 6 06:12:04 1997 Mike Meissner <meissner@cygnus.com>
* igen.c (print_itrace): Call trace_one_insn to trace
instructions, rather than doing it directly.
Mon May 5 14:11:46 1997 Mike Meissner <meissner@cygnus.com>
* gen-engine.c (engine_switch_leaf): Remove extra %s.
