1054 * emul_generic.c (emul_add_tree_options): Only require strict
1055 alignment if it was explicitly requested at configuration time.
1056 Don't make it the default for little-endian machines.
1057 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1058 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1059 THRM2, THRM3): Plop in the MPC750 SPR registers.
1060 (DABR): This is weird. This was HID5, but the PPC spec says this
1061 should be DABR; why did some random processor use it for something
1062 else? The HID5 entry dates back to the original checkin of the
1063 simulator code in 1995, so remove it.
1064 * sim_calls.c (register_names): Delete this; since the user can
1065 now change GDB's list of register names dynamically, we can't
1066 pretend there's a static mapping here.
1067 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1068 function to get the register name. That ought to be accurate.
1069 However, we're changing a compile-time dependency (using the
1070 REGISTER_NAMES macro) into a link- and run-time dependency
1071 (calling REGISTER_NAME, which happens to be a function call on the
1074 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1076 * igen.c(gen_semantics_[ch]): setup/use of new option

1081 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
1083 1998-12-01 Ken Raeburn <raeburn@cygnus.com>

1104 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1106 * table.c (table_open): For cygwin hosts, we need to use the
1107 return value from the read routine as the number of bytes to
1108 process. This apparently is due to text-mode vs binary-mode. If
1109 the mounts are done text-mode, then the size returnedby fstat()
1110 may be different than the number of bytes "read" in text mode.
1112 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>

1135 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1137 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1138 but there was no such target, only plain psim. So I changed the
1139 run target to depend on psim.

1143 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are

1547 determine the simulation speed by looking at the number of elapsed
1548 ticks recorded by the event queue.
1550 * psim.c (psim_write_register, psim_read_register): Force the cpu
1551 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1552 next cpu would be zero any way.
1554 * mon.c (mon_print_info): If possible, print the system cycle
1555 performance. This is an indication of the number of instructions
1558 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1560 * The code to allow an event queue to be updated during a signal
1561 was missing. For main.c, a cntrl-c simulation termination wasn't
1564 * The simulation would not correctly restart if an event requested
1565 that the simulation be halted.
1567 * psim.c (psim_options): Add hack to -i option to optionally
1568 include a level vis -i2.
1569 (psim_usage): Document.

1689 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1690 scratch variable is defined when a cache entry is beinf

1693 * gen-icache.c: Update.
