2000-12-12  Geoffrey Keating  <geoffk@redhat.com>

	* 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]).

	psim.c(is_num - added, psim_options): Parse and init new option.

	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>

	* configure: Regenerate.
	* emul_{netbsd,unix}.c (toplevel): No longer try to include

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

 	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>

	* The code to allow an event queue to be updated during a signal

	* psim.c (psim_options): Add hack to -i option to optionally
 	include a level vis -i2.

 	performed.

 	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>

 	here.  Update to new format.

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>

 	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.
	(print_icache_body): Remove code that was looking for *_is_0 and
 	then generating corresponding definitions.

	* 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.

 	object.
