Mon Jan 8 12:17:22 1996 Michael Meissner <meissner@tiktok.cygnus.com>
* device_table.c (register_init): Make format type correct.
Wed Jan 3 19:21:46 1996 Andrew Cagney <cagney@highland.com.au>
* emul_bugapi.c (emul_bugapi_create): Add nodes to init the
system-call trap to the emul instruction call instruction (Along
with an rfi and infinate loop).
* emul_bugapi.c (emul_bugapi_instruction_call): Expand to include
a few real PPC bug calls. Test with simple hello world.
Tue Jan 2 20:51:19 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
* device.h, device.c (device_child, device_sibling): New
functions. Return corresponding device value.
* emul_chirp.c (chirp_emul_child, chirp_emul_peer,
chirp_emul_parent): New functions - emulate corresponding OpenBoot
interfaces.
* device_table.c (register_init): Extend properties attached to
register init node to allow a specific processor's register to be
specified.
* emul_chirp.c (emul_chirp_create): Init SMP correctly - the
initial PC for all processors is an infinate loop but then, for
processor zero, is quickly changed to be the correct code starting
address.
* emul_chirp.c (emul_chirp_create): Add fake bootpath
et.al. properties to tree.
* emul_chirp.c (chirp_emul_getproplen): New function. Emulate the
getproplen OpenBoot call.
* emul_chirp.c (emul_chirp_instruction_call): Document other
possible chirp emulation internal states.
* emul_chirp.c (emul_chirp_instruction_call): Trace failed lookups
as well as successful ones.
* emul_chirp.c (emul_chirp_open): New function - handle open
client call.
* Makefile.in (maintainer-clean): Proper rule that eliminates more
junk.
Tue Dec 19 13:00:11 1995 Andrew Cagney <cagney@highland.com.au>
* emul_chirp.c (chirp_emul_exit): Full out call.
* device_table.c (htab_map_page): Wasn't handling byte swap when
creating entries in the hash table.
* device.c (device_tree_find_node): Allow primative wild-card match
of device names with the path.
FIXME: As mentioned earlier, the device stuff needs work to bring
it into line with OpenBoot. Part of this work is rewriting the
find_node function so that it behaves as specified in p1275.
Mon Dec 18 19:58:56 1995 Andrew Cagney <cagney@highland.com.au>
* emul_chrp.c (chirp_emul_write, chirp_emul_finddevice): add
better tracing.
* emul_chrp.c: Change return type of emul functions to int. Emul
functions either return -1 or zero so unsigned was a bit
dangerous.
* inline.h (*), igen.c, dgen.c, *: Update INLINE macros so that
they are paramaterised with the type of the function. Gets around
the problem of `static' needing to come first with `attribute'
comming last. Format declarations and definitions so that emacs
doesn't get confused.
Fri Dec 15 17:06:44 1995 Andrew Cagney <cagney@highland.com.au>
* std-config.h (PSIM_INLINE): Add missing inline configuration
control for the main loop.
* mon.c (mon_print_info): If monitoring disabled still print out
the number seconds used.
* psim.c (run_until_stop): Don't monitor the cache misses when
monitoring is disabled.
* configure.in (sim_mon, sim_monitor): Correct typo - sim_mon ->
sim_monitor for shell variable (or should that have been the other
way around?).
* vm.c (vm_synchronize_context): Fix wrong test for unsuported
change in endian-mode.
* std-config.h (WITH_REGPARM), inline.h (IDECODE_INLINE,
SEMANTICS_INLINE): Add -DWITH_REGPARM=<n> option. Enables the
__attribute__((__regparm(WITH_REGPARM))) for some functions.
configure with --enable-sim-cflags="-DWITH_REGPARAM=3" (say).
Unfortunatly it tickles a bug (gcc?) and can't be used.
Mon Dec 18 13:36:06 1995 Michael Meissner <meissner@tiktok.cygnus.com>
* device.c (device_tree_add_device): Make trace fprintf arguments
type correct.
* device_table.c (htab_decode_hash_table): Ditto.
(htab_map_binary): Ditto.
(htab_init_callback): Ditto.
* vm.c (om_virtual_to_real): Ditto.
Sat Dec 16 09:54:18 1995 Michael Meissner <meissner@wogglebug.tiac.net>
* emul_netbsd.c (emul_netbsd_create): Deal with new BFD that
