* sim-profile.c (profile_print_speed): Call
sim_events_elapsed_time instead of PROFILE_EXEC_TIME for moment.
* sim-events.c (sim_events_elapsed_time): New function return nr
host MS consumed by the simulator.
(sim_watch_valid): Use.
* sim-module.c (modules): Install sim_events very very early.
* sim-profile.c (profile_print): Call profile_print_pc.
(print_bar):
(profile_pc_init): New function, set up processor for PC
profiling.
(profile_print_pc): New function, print a PC profile.
(profile_pc_event): New function, sample PC.
* sim-profile.h (PROFILE_PC_COUNT, PROFILE_PC_START,
PROFILE_PC_END, PROFILE_PC_SHIFT, PROFILE_PC_SAMPLE_SIZE): Add to
profile struct.
* sim-options.c (sim_print_help): Pacify GCC.
* sim-n-core.h (sim_core_read_aligned_N,
sim_core_write_aligned_N): Add un-conditional profile call.
(sim_core_read_unaligned_N, sim_core_write_unaligned_N): Add
profile call when aligned read/write isn't used.
* sim-base.h: Include sim-profile, sim-model after sim-core &
sim-events allow sim-core to define useful values.
* sim-profile.c (OPTION_PROFILE_CORE): Define.
(profile_option_handler, profile_options): Add support for
--profile-core option.
(print_bar): Include when core profiling.
(profile_print_core): New function, print core profile.
* sim-config.c (print_sim_config): Print profile status.
* sim-profile.h (PROFILE_NEXT_IDX, PROFILE_core,
WITH_PROFILE_PC_P): Define.
(PROFILE_CORE_COUNT): Count each core-map/size separatly.
(PROFILE_COUNT_CORE): Define.
