1 1999-05-08 Felix Lee <flee@cygnus.com>
3 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
4 * configure: Regenerated to track ../common/aclocal.m4 changes.
6 1999-04-02 Keith Seitz <keiths@cygnus.com>
8 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
9 the frequency at which the poll_quit callback is called.
10 (poll_quit_count): New global.
11 (sim_io_poll_quit): Only call the poll_quit callback
12 after the specified POLL_QUIT_INTERVAL.
14 1999-02-22 Jim Lemke <jlemke@cygnus.com>
16 * dc-complex: Force expansion on all bits of field BO.
17 Previously, the least-significant (prediction) bit was ignored.
18 * ppc-instructions (conditional branches): Implement mpc860c0 option.
19 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
20 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
21 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
22 * interrupts.c (program_interrupt): Added handling for above interrupt.
24 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
26 Make the simulator compatible with the MPC750. It would be nicer
27 to make this a real multi-sim, but that's more work than we have
29 * emul_generic.c (emul_add_tree_options): Only require strict
30 alignment if it was explicitly requested at configuration time.
31 Don't make it the default for little-endian machines.
32 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
33 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
34 THRM2, THRM3): Plop in the MPC750 SPR registers.
35 (DABR): This is weird. This was HID5, but the PPC spec says this
36 should be DABR; why did some random processor use it for something
37 else? The HID5 entry dates back to the original checkin of the
38 simulator code in 1995, so remove it.
39 * sim_calls.c (register_names): Delete this; since the user can
40 now change GDB's list of register names dynamically, we can't
41 pretend there's a static mapping here.
42 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
43 function to get the register name. That ought to be accurate.
44 However, we're changing a compile-time dependency (using the
45 REGISTER_NAMES macro) into a link- and run-time dependency
46 (calling REGISTER_NAME, which happens to be a function call on the
49 1999-01-22 Jim Lemke <jlemke@cygnus.com>
51 * igen.c(gen_semantics_[ch]): setup/use of new option
53 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
54 ppc-instructions(the four branch insn groups): detect problematic br's.
55 psim.c(is_num - added, psim_options): Parse and init new option.
56 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
58 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
60 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

73 1998-11-19 Michael Meissner <meissner@cygnus.com>
75 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
76 fractional type, so that quiet NaN's aren't treated like
79 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
81 * table.c (table_open): For cygwin hosts, we need to use the
82 return value from the read routine as the number of bytes to
83 process. This apparently is due to text-mode vs binary-mode. If
84 the mounts are done text-mode, then the size returnedby fstat()
85 may be different than the number of bytes "read" in text mode.
87 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
89 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

100 * sim_calls.c (sim_fetch_register, sim_store_register):
101 return zero when nothing to do.
103 1998-06-26 Michael Meissner <meissner@cygnus.com>
105 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
106 * configure: Regenerate.
107 * emul_{netbsd,unix}.c (toplevel): No longer try to include
108 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
110 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
112 * Makefile.in: The run target depended on a target psim$(EXEEXT),
113 but there was no such target, only plain psim. So I changed the
114 run target to depend on psim.
116 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
118 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
119 now defined in ../common/aclocal.m4, and the double definition causes
120 problems with AC_SUBST of EXEEXT.

484 or doubles clock interrupts.
487 Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

522 determine the simulation speed by looking at the number of elapsed
523 ticks recorded by the event queue.
525 * psim.c (psim_write_register, psim_read_register): Force the cpu
526 to zero when it is either of `-1' or `nr_cpus'. In both cases the
527 next cpu would be zero any way.
529 * mon.c (mon_print_info): If possible, print the system cycle
530 performance. This is an indication of the number of instructions
533 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
535 * The code to allow an event queue to be updated during a signal
536 was missing. For main.c, a cntrl-c simulation termination wasn't
539 * The simulation would not correctly restart if an event requested
540 that the simulation be halted.
542 * psim.c (psim_options): Add hack to -i option to optionally
543 include a level vis -i2.
544 (psim_usage): Document.

659 * The code that put values in and extracted values from the cache
660 was too compilicated. The cache table did not allow values to be
661 computed from cache entries. #defines could only be used when a
662 cache was present, remove the restriction.
664 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
665 scratch variable is defined when a cache entry is beinf
