10 * ppc-instructions (Disabled_Exponent_Underflow): Increment
11 the exponent when denormalizing.
13 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
15 * configure: Regenerated to track ../common/aclocal.m4 changes.
17 1999-05-08 Felix Lee <flee@cygnus.com>
19 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
20 * configure: Regenerated to track ../common/aclocal.m4 changes.
22 1999-04-02 Keith Seitz <keiths@cygnus.com>
24 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
25 the frequency at which the poll_quit callback is called.
26 (poll_quit_count): New global.
27 (sim_io_poll_quit): Only call the poll_quit callback
28 after the specified POLL_QUIT_INTERVAL.
30 1999-02-22 Jim Lemke <jlemke@cygnus.com>
32 * dc-complex: Force expansion on all bits of field BO.
33 Previously, the least-significant (prediction) bit was ignored.
34 * ppc-instructions (conditional branches): Implement mpc860c0 option.
35 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
36 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
37 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
38 * interrupts.c (program_interrupt): Added handling for above interrupt.
40 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
42 Make the simulator compatible with the MPC750. It would be nicer
43 to make this a real multi-sim, but that's more work than we have
45 * emul_generic.c (emul_add_tree_options): Only require strict
46 alignment if it was explicitly requested at configuration time.
47 Don't make it the default for little-endian machines.
48 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
49 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
50 THRM2, THRM3): Plop in the MPC750 SPR registers.
51 (DABR): This is weird. This was HID5, but the PPC spec says this
52 should be DABR; why did some random processor use it for something
53 else? The HID5 entry dates back to the original checkin of the
54 simulator code in 1995, so remove it.
55 * sim_calls.c (register_names): Delete this; since the user can
56 now change GDB's list of register names dynamically, we can't
57 pretend there's a static mapping here.
58 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
59 function to get the register name. That ought to be accurate.
60 However, we're changing a compile-time dependency (using the
61 REGISTER_NAMES macro) into a link- and run-time dependency
62 (calling REGISTER_NAME, which happens to be a function call on the
65 1999-01-22 Jim Lemke <jlemke@cygnus.com>
67 * igen.c(gen_semantics_[ch]): setup/use of new option

71 psim.c(is_num - added, psim_options): Parse and init new option.
72 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
74 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
76 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

92 fractional type, so that quiet NaN's aren't treated like
95 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
97 * table.c (table_open): For cygwin hosts, we need to use the
98 return value from the read routine as the number of bytes to
99 process. This apparently is due to text-mode vs binary-mode. If
100 the mounts are done text-mode, then the size returnedby fstat()
101 may be different than the number of bytes "read" in text mode.
103 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>

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

539 ticks recorded by the event queue.
541 * psim.c (psim_write_register, psim_read_register): Force the cpu
542 to zero when it is either of `-1' or `nr_cpus'. In both cases the

551 * The code to allow an event queue to be updated during a signal
552 was missing. For main.c, a cntrl-c simulation termination wasn't
555 * The simulation would not correctly restart if an event requested
556 that the simulation be halted.
558 * psim.c (psim_options): Add hack to -i option to optionally
559 include a level vis -i2.
560 (psim_usage): Document.

613 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
615 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
616 debug.c. It could be much simpler.

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

702 * configure.in (enable-sim-icache): Clarify description. Make
703 #define one of the defaults regardless of the cache. Probably
