Wed Sep 25 16:31:41 1996 Michael Meissner <meissner@tiktok.cygnus.com>
* simops.c (OP_{6E01,6A01,6E1F,6A00}): Print both words being
stored if tracing.
Mon Sep 23 17:55:30 1996 Michael Meissner <meissner@tiktok.cygnus.com>
* simops.c (op_types): Add OP_{CONSTANT8,R2,R3}.
(trace_input_func): Add support for OP_{CONSTANT8,R2,R3}.
(OP_{4900,24800000,4800,4A00,4B00,4D00,4C00}): Add OP_R2 and OP_R3
to call/subroutine returns to trace the first two arguments and
the return value. For small jumps, use CONSTANT8, not CONSTANT16.
Fri Sep 20 15:36:45 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
* interp.c (sim_create_inferior): Reinitialize State every time
