1999-04-02  Keith Seitz  <keiths@cygnus.com>

	* sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
	the frequency at which the poll_quit callback is called.
	(poll_quit_count): New global.
	(sim_io_poll_quit): Only call the poll_quit callback
	after the specified POLL_QUIT_INTERVAL.

1999-02-22  Jim Lemke  <jlemke@cygnus.com>

	* dc-complex: Force expansion on all bits of field BO.
	Previously, the least-significant (prediction) bit was ignored.
	* ppc-instructions (conditional branches): Implement mpc860c0 option.
	* igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
	* psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
	* interrupts.h: Added "mpc860c0_instruction_program_interrupt".
	* interrupts.c (program_interrupt): Added handling for above interrupt.

1999-02-01  Jim Blandy  <jimb@zwingli.cygnus.com>

	Make the simulator compatible with the MPC750.  It would be nicer
	to make this a real multi-sim, but that's more work than we have
	time for.
	* emul_generic.c (emul_add_tree_options): Only require strict
	alignment if it was explicitly requested at configuration time.
	Don't make it the default for little-endian machines.
	* ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
 	MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
 	THRM2, THRM3): Plop in the MPC750 SPR registers.
	(DABR): This is weird.  This was HID5, but the PPC spec says this
 	should be DABR; why did some random processor use it for something
 	else?  The HID5 entry dates back to the original checkin of the
	simulator code in 1995, so remove it.
	* sim_calls.c (register_names): Delete this; since the user can
	now change GDB's list of register names dynamically, we can't
	pretend there's a static mapping here.
	(sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
 	function to get the register name.  That ought to be accurate.
  	However, we're changing a compile-time dependency (using the
 	REGISTER_NAMES macro) into a link- and run-time dependency
	(calling REGISTER_NAME, which happens to be a function call on the
	PPC).

1999-01-22  Jim Lemke <jlemke@cygnus.com>

	* igen.c(gen_semantics_[ch]): setup/use of new option
	(-o mpc860c0[=n]).
	interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
	ppc-instructions(the four branch insn groups): detect problematic br's.
	psim.c(is_num - added, psim_options): Parse and init new option.
	These changes are currently under #ifdef WITH_OPTION_MPC860C0.

1998-12-01  Ken Raeburn  <raeburn@cygnus.com>

	* hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

Fri Nov 20 12:17:28 1998  Andrew Cagney  <cagney@b1.cygnus.com>

	* main.c (sim_io_poll_quit): Stub function.

	* events.c (SIM_EVENTS_POLL_RATE): Define.
	(sim_events_poll): Copy function from common/sim-events.c.
	(event_queue_init): Copy scheduling of sim_events_poll from same.

	* sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
 	poll the external environment.

1998-11-19  Michael Meissner  <meissner@cygnus.com>

	* ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
	fractional type, so that quiet NaN's aren't treated like
	Infinities.

Mon Sep 28 09:42:45 1998  Drew Moseley  <dmoseley@cygnus.com>

	* table.c (table_open): For cygwin hosts, we need to use the
 	return value from the read routine as the number of bytes to
 	process.  This apparently is due to text-mode vs binary-mode.  If
 	the mounts are done text-mode, then the size returnedby fstat()
 	may be different than the number of bytes "read" in text mode.

Sun Oct  4 00:50:47 1998  Felix Lee  <flee@cygnus.com>

	* emul_netbsd.c (do_open): fix order-of-evaluation problem.
	(do_close): ditto.
	(do_fstat): ditto.
	(do_lstat): ditto.

1998-09-03  Michael Meissner  <meissner@cygnus.com>

	* emul_{netbsd,unix}.c: Update copyright year.

Mon Jun 29 10:57:36 1998  Michael Snyder  <msnyder@cleaver.cygnus.com>

	* sim_calls.c (sim_fetch_register, sim_store_register):
	return zero when nothing to do.

1998-06-26  Michael Meissner  <meissner@cygnus.com>

	* configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
	* configure: Regenerate.
	* emul_{netbsd,unix}.c (toplevel): No longer try to include
	sys/mount.h. It conflicts on Linux when gnu libc2 is used.

Tue May 12 12:10:33 PDT 1998  James Ingham  <jingham@leda.cygnus.com>

	* Makefile.in: The run target depended on a target psim$(EXEEXT),
	but there was no such target, only plain psim.  So I changed the
	run target to depend on psim.

Sat May  2 01:10:12 1998  Stu Grossman  <grossman@babylon-5.cygnus.com>

	* aclocal.m4:  Remove defs of AM_EXEEXT and AM_CYGWIN32.  These are
	now defined in ../common/aclocal.m4, and the double definition causes
	problems with AC_SUBST of EXEEXT.
	* configure:  Regenerate.
	
Wed Apr 29 15:44:52 1998  Geoffrey Noer  <noer@cygnus.com>

	* configure: regenerate with autoconf 2.12.1.
	* Makefile.in: add EXEEXT support

Sun Apr 26 15:31:55 1998  Tom Tromey  <tromey@creche>

	* configure: Regenerated to track ../common/aclocal.m4 changes.
	* config.in: Ditto.

Sun Apr 26 15:19:51 1998  Tom Tromey  <tromey@cygnus.com>

	* acconfig.h: New file.
	* configure.in: Reverted change of Apr 24; use sinclude again.
	Don't call AC_C_CROSS.

Fri Apr 24 14:16:40 1998  Tom Tromey  <tromey@creche>

	* configure: Regenerated to track ../common/aclocal.m4 changes.
	* config.in: Ditto.

Fri Apr 24 11:18:46 1998  Tom Tromey  <tromey@cygnus.com>

	* Makefile.in (top_builddir): New macro.
	(INTLLIBS): New macro.
	(INTLDEPS): Likewise.
	(psim): Depend on INTLDEPS; link against INTLLIBS.
	* configure.in: Call CY_GNU_GETTEXT.

Wed Apr 22 14:28:48 1998  Michael Meissner  <meissner@cygnus.com>

	* configure: Regenerate with autoconf 2.12.1.

Fri Mar 13 09:25:58 1998  Andrew Cagney  <cagney@b1.cygnus.com>

 	length parameter.  Return -1.

Mon Feb  9 14:13:14 1998  Andrew Cagney  <cagney@b1.cygnus.com>

	* ppc-instructions (fdiv, fdivs): Check for divide by zero.
	(is_invalid_zero_divide, invalid_zero_divide_operation): New
 	functions.
	
Wed Dec 10 17:38:28 1997  Andrew Cagney  <cagney@b1.cygnus.com>

	* sim_calls.c (sim_load): Do not parse PROG using buildargv, use
 	raw value instead.

1997-11-05  Felix Lee  <flee@cygnus.com>

	* emul_chirp.c: #ifdef HAVE_UNISTD_H

 	flush_stdout.

Fri Sep 26 09:50:29 1997  Andrew Cagney  <cagney@b1.cygnus.com>

	* ppc-instructions (sraw, slw, srw): From Charles Lefurgy, Fix

 	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.

	* 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>

	* 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

 	always update the cache_entries semantic and address fields.

	* gen-idecode.c (print_idecode_switch_illegal): Include a break

        no longer needed).

	* psim.c (run_until_stop): Delete the old run_until_stop function
        instead calling the idecode_run and idecode_run_until_stop
