1 1999-04-02 Keith Seitz <keiths@cygnus.com>
3 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
4 the frequency at which the poll_quit callback is called.
5 (poll_quit_count): New global.
6 (sim_io_poll_quit): Only call the poll_quit callback
7 after the specified POLL_QUIT_INTERVAL.
9 1999-02-22 Jim Lemke <jlemke@cygnus.com>
11 * dc-complex: Force expansion on all bits of field BO.
12 Previously, the least-significant (prediction) bit was ignored.
13 * ppc-instructions (conditional branches): Implement mpc860c0 option.
14 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
15 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
16 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
17 * interrupts.c (program_interrupt): Added handling for above interrupt.
19 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
21 Make the simulator compatible with the MPC750. It would be nicer
22 to make this a real multi-sim, but that's more work than we have
24 * emul_generic.c (emul_add_tree_options): Only require strict
25 alignment if it was explicitly requested at configuration time.
26 Don't make it the default for little-endian machines.
27 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
28 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
29 THRM2, THRM3): Plop in the MPC750 SPR registers.
30 (DABR): This is weird. This was HID5, but the PPC spec says this
31 should be DABR; why did some random processor use it for something
32 else? The HID5 entry dates back to the original checkin of the
33 simulator code in 1995, so remove it.
34 * sim_calls.c (register_names): Delete this; since the user can
35 now change GDB's list of register names dynamically, we can't
36 pretend there's a static mapping here.
37 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
38 function to get the register name. That ought to be accurate.
39 However, we're changing a compile-time dependency (using the
40 REGISTER_NAMES macro) into a link- and run-time dependency
41 (calling REGISTER_NAME, which happens to be a function call on the
44 1999-01-22 Jim Lemke <jlemke@cygnus.com>
46 * igen.c(gen_semantics_[ch]): setup/use of new option
48 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
49 ppc-instructions(the four branch insn groups): detect problematic br's.
50 psim.c(is_num - added, psim_options): Parse and init new option.
51 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
53 1998-12-01 Ken Raeburn <raeburn@cygnus.com>

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

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

518 ticks recorded by the event queue.
520 * psim.c (psim_write_register, psim_read_register): Force the cpu
521 to zero when it is either of `-1' or `nr_cpus'. In both cases the
522 next cpu would be zero any way.
524 * mon.c (mon_print_info): If possible, print the system cycle
525 performance. This is an indication of the number of instructions
528 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
530 * The code to allow an event queue to be updated during a signal

655 was too compilicated. The cache table did not allow values to be

659 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
660 scratch variable is defined when a cache entry is beinf
