3 Make the simulator compatible with the MPC750. It would be nicer
4 to make this a real multi-sim, but that's more work than we have
6 * emul_generic.c (emul_add_tree_options): Only require strict
7 alignment if it was explicitly requested at configuration time.
8 Don't make it the default for little-endian machines.
9 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
10 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
11 THRM2, THRM3): Plop in the MPC750 SPR registers.
12 (DABR): This is weird. This was HID5, but the PPC spec says this
13 should be DABR; why did some random processor use it for something
14 else? The HID5 entry dates back to the original checkin of the
15 simulator code in 1995, so remove it.
16 * sim_calls.c (register_names): Delete this; since the user can
17 now change GDB's list of register names dynamically, we can't
18 pretend there's a static mapping here.
19 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
20 function to get the register name. That ought to be accurate.
21 However, we're changing a compile-time dependency (using the
22 REGISTER_NAMES macro) into a link- and run-time dependency
23 (calling REGISTER_NAME, which happens to be a function call on the
26 1999-01-22 Jim Lemke <jlemke@cygnus.com>
28 * igen.c(gen_semantics_[ch]): setup/use of new option
30 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
31 ppc-instructions(the four branch insn groups): detect problematic br's.
32 psim.c(is_num - added, psim_options): Parse and init new option.
33 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
35 1998-12-01 Ken Raeburn <raeburn@cygnus.com>

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

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

499 determine the simulation speed by looking at the number of elapsed
500 ticks recorded by the event queue.
502 * psim.c (psim_write_register, psim_read_register): Force the cpu
503 to zero when it is either of `-1' or `nr_cpus'. In both cases the
504 next cpu would be zero any way.
506 * mon.c (mon_print_info): If possible, print the system cycle
507 performance. This is an indication of the number of instructions
510 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
512 * The code to allow an event queue to be updated during a signal

540 * gen-idecode.c (print_run_until_stop_body): Call
541 event_queue_process_events to clear possibly pending events before
542 starting a simulation run. Re-arange main loop so that simulator
543 is correctly restarted when an event halts the simulation.

546 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
549 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

637 was too compilicated. The cache table did not allow values to be
638 computed from cache entries. #defines could only be used when a
639 cache was present, remove the restriction.
641 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
642 scratch variable is defined when a cache entry is beinf
