981 Make the simulator compatible with the MPC750. It would be nicer
982 to make this a real multi-sim, but that's more work than we have
983 time for.
984 * emul_generic.c (emul_add_tree_options): Only require strict
985 alignment if it was explicitly requested at configuration time.
986 Don't make it the default for little-endian machines.
987 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
988 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
989 THRM2, THRM3): Plop in the MPC750 SPR registers.
990 (DABR): This is weird. This was HID5, but the PPC spec says this
991 should be DABR; why did some random processor use it for something
992 else? The HID5 entry dates back to the original checkin of the
993 simulator code in 1995, so remove it.
994 * sim_calls.c (register_names): Delete this; since the user can
995 now change GDB's list of register names dynamically, we can't
996 pretend there's a static mapping here.
997 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
998 function to get the register name. That ought to be accurate.
999 However, we're changing a compile-time dependency (using the
1000 REGISTER_NAMES macro) into a link- and run-time dependency
1001 (calling REGISTER_NAME, which happens to be a function call on the
1002 PPC).

1005

1034Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1035
1036 * table.c (table_open): For cygwin hosts, we need to use the
1037 return value from the read routine as the number of bytes to
1038 process. This apparently is due to text-mode vs binary-mode. If
1039 the mounts are done text-mode, then the size returnedby fstat()
1040 may be different than the number of bytes "read" in text mode.

1066
1067 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1068 but there was no such target, only plain psim. So I changed the
1069 run target to depend on psim.

1346
1347 * Many of the ppc-opcode-* files are identical baring the type of

1477 determine the simulation speed by looking at the number of elapsed
1478 ticks recorded by the event queue.
72f4393d 1479
c906108c
SS		 1480 * psim.c (psim_write_register, psim_read_register): Force the cpu
1481 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1482 next cpu would be zero any way.
1483
1484 * mon.c (mon_print_info): If possible, print the system cycle
1485 performance. This is an indication of the number of instructions
1486 per second.
1487
1488Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1489
1490 * The code to allow an event queue to be updated during a signal
1491 was missing. For main.c, a cntrl-c simulation termination wasn't
1492 handled cleanly.
72f4393d 1493
c906108c
SS		 1494 * The simulation would not correctly restart if an event requested
1495 that the simulation be halted.
72f4393d 1496
c906108c
SS		 1497 * psim.c (psim_options): Add hack to -i option to optionally

1503 (main): Catch CNTRL-C signals with the function cntrl_c.
1504
1505 * events.c (event_queue_process): Mask interrupts while
1506 manipulating the async event queue.

1511 the processing state when processing has started. Adjust code
1512 so that it is tolerant of halts.
1513 (event_queue_init): Start the event queue out with processing
1514 false.
1515 (event_queue_tick): Check that processing isn't still being
1516 performed.

c906108c
SS		 1518 * gen-idecode.c (print_run_until_stop_body): Call
1519 event_queue_process_events to clear possibly pending events before
1520 starting a simulation run. Re-arange main loop so that simulator

1528
1529 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1530 RA. Based on instruction frequency stats, expand additional
1531 instructions.

72f4393d 1533
c906108c

1546
1547 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1548 to be initialized independant of the rest of the simulation
1549 initalization. Otherwize a trace option explictly set from gdb
1550 could be overridden by hw_trace.
1551
1552 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1553
1554 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,

1590
1591 * For expressions like (RA == 0) that are entered in to the cache
1592 as RA_is_0. If possible generate the result of the expression so
1593 that the compiler gets a better chance of eliminating dead
1594 branches.
1595
1596 * gen-icache.c (print_icache_extraction): For a cache entry of
1597 the form <name>_is_<const> where it is a boolean field, generate
1598 the result of the expression instead of the expression its self.
1599 (print_icache_body): Remove code that was looking for *_is_0 and
1600 then generating corresponding definitions.
1601
1602 * gen-icache.c (print_icache_struct): If there is no cache, do not
1603 output expressions in idecode.h file.

1612Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1613
1614 * The code that put values in and extracted values from the cache
1615 was too compilicated. The cache table did not allow values to be
1616 computed from cache entries. #defines could only be used when a
1617 cache was present, remove the restriction.
1618
1619 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1620 scratch variable is defined when a cache entry is beinf
1621 filled. Change the definition of a COMPUTE variable to be defined
1622 when the cache entry is being used.
1623 * gen-icache.c: Update.
72f4393d 1624
c906108c
SS		 1625 * ld-cache.h, ld-cache.c: Change field names so that their meaning

c906108c
SS		 1629 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1630 different types of cache code - put into cache, extract from
1631 cache, no cache - an explicit argument to print_icache_body.

72f4393d 1633
c906108c
SS		 1634 * gen-semantics.c (print_c_semantic): Update use.

1639 cache.
1640
1641 * configure.in (enable-sim-icache): Clarify description. Make
1642 #define one of the defaults regardless of the cache. Probably
1643 should revamp and add a separate option.

1656
1657 * The cap object was retaining a reference to the instance of a
1658 device after it was deleted. Instead add and remove cap's from the
1659 cap db as they are created and deleted. This ensuring that a
1660 capibility is only used during the lifetime of the corresponding
1661 object.
72f4393d 1662
c906108c
SS		 1663 * cap.h, cap.c: Correct cap type - was signed32 should be

2955 always update the cache_entries semantic and address fields.
2956
2957 * gen-idecode.c (print_idecode_switch_illegal): Include a break

c906108c
SS		 3002
3003 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and

72f4393d 3049 instead of just the code to handle a single instruction issue.
c906108c
SS		 3050 * : Have the generated idecode.c include inline.c (instead of psim.c).
3051
3052 * std-config.h: Change psim.c so that it isn't inlined (as this is

SS		 3054
3055 * psim.c (run_until_stop): Delete the old run_until_stop function
72f4393d
L		 3056 instead calling the idecode_run and idecode_run_until_stop
3057 functions that gen-idecode.c is now creating.

72f4393d
L		 3087 of ITRACE. The CPP line directives would have previously set the

72f4393d
L		 3093 idecode generation option. Instead of generating and calling

4075
4076 * device.c (attach_device_interrupt_edge): New. Interrupt model
72f4393d
L		 4077 did not allow interrupts to be wired up as a general net (edges).
4078 Re-implement so that interrupt events can be passed to multiple
4079 controllers and interrupt controllers can further propogate
4080 interrupt events.
