18 * emul_netbsd.c (do_open): Translate the flag parameter to the
19 open syscall to the numbers supported by the host.
21 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
23 * sim-endian.h: Don't have parameters on macro definitions which
24 are simply renaming functions, to permit use of XCONCAT2 in both
25 the macro name and the arguments in a use of such a definition.
27 2000-11-15 Jim Blandy <jimb@redhat.com>
29 * sim_calls.c: Doc fix.
30 (sim_fetch_register, sim_store_register): Call

59 the exponent when denormalizing.
61 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
63 * configure: Regenerated to track ../common/aclocal.m4 changes.
65 1999-05-08 Felix Lee <flee@cygnus.com>
67 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
68 * configure: Regenerated to track ../common/aclocal.m4 changes.
70 1999-04-02 Keith Seitz <keiths@cygnus.com>
72 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
73 the frequency at which the poll_quit callback is called.
74 (poll_quit_count): New global.
75 (sim_io_poll_quit): Only call the poll_quit callback
76 after the specified POLL_QUIT_INTERVAL.
78 1999-02-22 Jim Lemke <jlemke@cygnus.com>
80 * dc-complex: Force expansion on all bits of field BO.
81 Previously, the least-significant (prediction) bit was ignored.

88 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
90 Make the simulator compatible with the MPC750. It would be nicer
91 to make this a real multi-sim, but that's more work than we have
93 * emul_generic.c (emul_add_tree_options): Only require strict
94 alignment if it was explicitly requested at configuration time.
95 Don't make it the default for little-endian machines.
96 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
97 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
98 THRM2, THRM3): Plop in the MPC750 SPR registers.
99 (DABR): This is weird. This was HID5, but the PPC spec says this
100 should be DABR; why did some random processor use it for something
101 else? The HID5 entry dates back to the original checkin of the
102 simulator code in 1995, so remove it.
103 * sim_calls.c (register_names): Delete this; since the user can
104 now change GDB's list of register names dynamically, we can't
105 pretend there's a static mapping here.
106 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
107 function to get the register name. That ought to be accurate.
108 However, we're changing a compile-time dependency (using the
109 REGISTER_NAMES macro) into a link- and run-time dependency
110 (calling REGISTER_NAME, which happens to be a function call on the
113 1999-01-22 Jim Lemke <jlemke@cygnus.com>

119 psim.c(is_num - added, psim_options): Parse and init new option.
120 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
122 1998-12-01 Ken Raeburn <raeburn@cygnus.com>

140 fractional type, so that quiet NaN's aren't treated like
143 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
145 * table.c (table_open): For cygwin hosts, we need to use the
146 return value from the read routine as the number of bytes to
147 process. This apparently is due to text-mode vs binary-mode. If
148 the mounts are done text-mode, then the size returnedby fstat()
149 may be different than the number of bytes "read" in text mode.
151 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
153 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

170 * configure: Regenerate.
171 * emul_{netbsd,unix}.c (toplevel): No longer try to include
172 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
174 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
176 * Makefile.in: The run target depended on a target psim$(EXEEXT),
177 but there was no such target, only plain psim. So I changed the
178 run target to depend on psim.
180 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
182 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
183 now defined in ../common/aclocal.m4, and the double definition causes
184 problems with AC_SUBST of EXEEXT.

583 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
585 * When performance monitoring is disabled, it is still possible to
586 determine the simulation speed by looking at the number of elapsed
587 ticks recorded by the event queue.
589 * psim.c (psim_write_register, psim_read_register): Force the cpu
590 to zero when it is either of `-1' or `nr_cpus'. In both cases the
591 next cpu would be zero any way.
593 * mon.c (mon_print_info): If possible, print the system cycle
594 performance. This is an indication of the number of instructions
597 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
599 * The code to allow an event queue to be updated during a signal
600 was missing. For main.c, a cntrl-c simulation termination wasn't
603 * The simulation would not correctly restart if an event requested
604 that the simulation be halted.

607 include a level vis -i2.
608 (psim_usage): Document.

661 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
663 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
664 debug.c. It could be much simpler.
666 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

723 * The code that put values in and extracted values from the cache
724 was too compilicated. The cache table did not allow values to be
725 computed from cache entries. #defines could only be used when a
726 cache was present, remove the restriction.
728 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
729 scratch variable is defined when a cache entry is beinf
730 filled. Change the definition of a COMPUTE variable to be defined
731 when the cache entry is being used.
732 * gen-icache.c: Update.
734 * ld-cache.h, ld-cache.c: Change field names so that their meaning

750 * configure.in (enable-sim-icache): Clarify description. Make
751 #define one of the defaults regardless of the cache. Probably
752 should revamp and add a separate option.
