From 0f2811d1c539d123b69ffa0da3cd13febd10ef43 Mon Sep 17 00:00:00 2001 From: David Edelsohn Date: Thu, 17 Apr 1997 09:37:02 +0000 Subject: [PATCH] * Make-common.in (sim-options.o, sim-load.o): Add rules for. (sim_main_headers): Add sim-trace.h. * run.c (exec_bfd, target_byte_order): Delete. (main): Pass -E to sim_open. Delete code to load sections, call sim_load instead. Check return code of sim_create_inferior. * sim-base.h (CURRENT_STATE): Define. (sim_state_base): Make typedef. New members options, prog_argv, prog_bfd, text_{section,start,end}, start_addr, simcache_size, mem_size, memory [+ corresponding access macros].
