It would be nicer + to make this a real multi-sim, but that's more work than we have + time for. + * emul_generic.c (emul_add_tree_options): Only require strict + alignment if it was explicitly requested at configuration time. + Don't make it the default for little-endian machines. + * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4, + MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1, + THRM2, THRM3): Plop in the MPC750 SPR registers. + (DABR): This is weird. This was HID5, but the PPC spec says this + should be DABR; why did some random processor use it for something + else? The HID5 entry dates back to the original checkin of the + simulator code in 1995, so remove it. + * sim_calls.c (register_names): Delete this; since the user can + now change GDB's list of register names dynamically, we can't + pretend there's a static mapping here. + (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME + function to get the register name. That ought to be accurate. + However, we're changing a compile-time dependency (using the + REGISTER_NAMES macro) into a link- and run-time dependency + (calling REGISTER_NAME, which happens to be a function call on the + PPC). + +1999-01-22 Jim Lemke <jlemke@cygnus.com> + + * igen.c(gen_semantics_[ch]): setup/use of new option + (-o mpc860c0[=n]). + interrupts.[ch](mpc860c0_instruction_program_interrupt): added. + ppc-instructions(the four branch insn groups): detect problematic br's. + psim.c(is_num - added, psim_options): Parse and init new option. + These changes are currently under #ifdef WITH_OPTION_MPC860C0. + +1998-12-01 Ken Raeburn <raeburn@cygnus.com> + + * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99. + +Fri Nov 20 12:17:28 1998 Andrew Cagney <cagney@b1.cygnus.com> + + * main.c (sim_io_poll_quit): Stub function. + + * events.c (SIM_EVENTS_POLL_RATE): Define. + (sim_events_poll): Copy function from common/sim-events.c. + (event_queue_init): Copy scheduling of sim_events_poll from same. + + * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function, + poll the external environment. + +1998-11-19 Michael Meissner <meissner@cygnus.com> + + * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the + fractional type, so that quiet NaN's aren't treated like + Infinities. + +Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com> + + * table.c (table_open): For cygwin hosts, we need to use the + return value from the read routine as the number of bytes to + process. This apparently is due to text-mode vs binary-mode. If + the mounts are done text-mode, then the size returnedby fstat() + may be different than the number of bytes "read" in text mode. + +Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com> + + * emul_netbsd.c (do_open): fix order-of-evaluation problem. + (do_close): ditto. + (do_fstat): ditto. + (do_lstat): ditto. + +1998-09-03 Michael Meissner <meissner@cygnus.com> + + * emul_{netbsd,unix}.c: Update copyright year. + +Mon Jun 29 10:57:36 1998 Michael Snyder <msnyder@cleaver.cygnus.com> + + * sim_calls.c (sim_fetch_register, sim_store_register): + return zero when nothing to do. + +1998-06-26 Michael Meissner <meissner@cygnus.com> + + * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h. + * configure: Regenerate. + * emul_{netbsd,unix}.c (toplevel): No longer try to include + sys/mount.h. It conflicts on Linux when gnu libc2 is used. + +Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com> + + * Makefile.in: The run target depended on a target psim$(EXEEXT), + but there was no such target, only plain psim. So I changed the + run target to depend on psim. + +Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com> + + * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32.
