determine the simulation speed by looking at the number of elapsed
ticks recorded by the event queue.
* psim.c (psim_write_register, psim_read_register): Force the cpu
to zero when it is either of `-1' or `nr_cpus'. In both cases the
next cpu would be zero any way.
* mon.c (mon_print_info): If possible, print the system cycle
performance. This is an indication of the number of instructions
per second.
Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

that the simulation be halted.
* psim.c (psim_options): Add hack to -i option to optionally
include a level vis -i2.
(psim_usage): Document.

starting a simulation run. Re-arange main loop so that simulator
is correctly restarted when an event halts the simulation.
* psim.c (psim_halt): Handle an event halting the simulation.
* psim.c (psim_init): Adjust initial cpu - == -1 - to match
reworked idecode.
Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

* ppc-instructions: Change all `RA == 0' to RA_is_0.
* ppc-opcode-stupid: Move all but the basic table in -complex into
here. Update to new format.

Implement.
Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
* hw_trace.c (hw_trace_init_data): Delete. The trace options need
to be initialized independant of the rest of the simulation
initalization. Otherwize a trace option explictly set from gdb
could be overridden by hw_trace.
* psim.c (psim_options): Clarify reason why the trace ioctl occures.
* FIXME: The trace code is too scattered - hw_trace.c, psim.c,
debug.c. It could be much simpler.
Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

device so that it supports this.

as RA_is_0. If possible generate the result of the expression so
that the compiler gets a better chance of eliminating dead
branches.
* gen-icache.c (print_icache_extraction): For a cache entry of
the form <name>_is_<const> where it is a boolean field, generate
the result of the expression instead of the expression its self.

output expressions in idecode.h file.

Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
* The code that put values in and extracted values from the cache
was too compilicated. The cache table did not allow values to be
computed from cache entries. #defines could only be used when a
cache was present, remove the restriction.
* ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
scratch variable is defined when a cache entry is beinf
filled. Change the definition of a COMPUTE variable to be defined
when the cache entry is being used.
* gen-icache.c: Update.
* ld-cache.h, ld-cache.c: Change field names so that their meaning
is more obvious. old_name->field_name, new_name->derived_name.
* gen-icache.c: Update
* gen-icache.h, gen-icache.c (print_icache_body): Make the three
different types of cache code - put into cache, extract from
cache, no cache - an explicit argument to print_icache_body.
* gen-icache.c (print_icache_extraction): Ditto.
* gen-semantics.c (print_c_semantic): Update use.
* gen-idecode.c (print_jump_insn): Update use.

* igen.c (main): Change 'R' option so that it does not force the
cache.
* configure.in (enable-sim-icache): Clarify description. Make
#define one of the defaults regardless of the cache. Probably
should revamp and add a separate option.
Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
* pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1..3.
(is_iso9660): New function, verify a CD9660 File system.

partition selection is supported.
Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

object.

signed_cell.
