1039 Make the simulator compatible with the MPC750. It would be nicer
1040 to make this a real multi-sim, but that's more work than we have
1041 time for.
1042 * emul_generic.c (emul_add_tree_options): Only require strict
1043 alignment if it was explicitly requested at configuration time.
1044 Don't make it the default for little-endian machines.
1045 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1046 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1047 THRM2, THRM3): Plop in the MPC750 SPR registers.
1048 (DABR): This is weird. This was HID5, but the PPC spec says this
1049 should be DABR; why did some random processor use it for something
1050 else? The HID5 entry dates back to the original checkin of the
1051 simulator code in 1995, so remove it.
1052 * sim_calls.c (register_names): Delete this; since the user can
1053 now change GDB's list of register names dynamically, we can't
1054 pretend there's a static mapping here.
1055 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1056 function to get the register name. That ought to be accurate.
1057 However, we're changing a compile-time dependency (using the
1058 REGISTER_NAMES macro) into a link- and run-time dependency
1059 (calling REGISTER_NAME, which happens to be a function call on the
1060 PPC).
1061

1092Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1093
1094 * table.c (table_open): For cygwin hosts, we need to use the
1095 return value from the read routine as the number of bytes to
1096 process. This apparently is due to text-mode vs binary-mode. If
1097 the mounts are done text-mode, then the size returnedby fstat()
1098 may be different than the number of bytes "read" in text mode.

1123Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1124
1125 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1126 but there was no such target, only plain psim. So I changed the
1127 run target to depend on psim.
1128

1450
1451 * Property create/initialization still wasn't correctly ordered.

1470
1471 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1472 works for normal and boolean table entries.
1473
1474 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
1475 valid. Handle this just like *_{read,write}_register now handles

1489 max iterations exceeded.
1490
1491 * gen-idecode.c: Re-work the table lookup code so that it assumes
1492 that the entry is a leaf by default. Simplify the boolean table
1493 entry code so that it involves a mask + test instead of shift +
1494 shift + mask + test.
1495

1524
1525 * igen wasn't aborting if the opcode table contained no valid
1526 fields.
72f4393d 1527
c906108c
SS		 1528 * misc.c (name2i): Possibly abort if an invalid name is

1534 * When performance monitoring is disabled, it is still possible to
1535 determine the simulation speed by looking at the number of elapsed
1536 ticks recorded by the event queue.
72f4393d 1537
c906108c
SS		 1538 * psim.c (psim_write_register, psim_read_register): Force the cpu
1539 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1540 next cpu would be zero any way.
1541
1542 * mon.c (mon_print_info): If possible, print the system cycle
1543 performance. This is an indication of the number of instructions
1544 per second.
1545
1546Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1547
1548 * The code to allow an event queue to be updated during a signal
1549 was missing. For main.c, a cntrl-c simulation termination wasn't
1550 handled cleanly.
72f4393d 1551
c906108c
SS		 1552 * The simulation would not correctly restart if an event requested

72f4393d 1554
c906108c
SS		 1555 * psim.c (psim_options): Add hack to -i option to optionally

1569 the processing state when processing has started. Adjust code
1570 so that it is tolerant of halts.
1571 (event_queue_init): Start the event queue out with processing
1572 false.
1573 (event_queue_tick): Check that processing isn't still being
1574 performed.
72f4393d 1575
c906108c
SS		 1576 * gen-idecode.c (print_run_until_stop_body): Call
1577 event_queue_process_events to clear possibly pending events before
1578 starting a simulation run. Re-arange main loop so that simulator
1579 is correctly restarted when an event halts the simulation.
1580

1586
1587 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1588 RA. Based on instruction frequency stats, expand additional
1589 instructions.
1590 * ppc-instructions: Change all `RA == 0' to RA_is_0.
72f4393d 1591
c906108c

1598Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1599

72f4393d 1602
c906108c
SS		 1603Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1604
1605 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1606 to be initialized independant of the rest of the simulation
1607 initalization. Otherwize a trace option explictly set from gdb
1608 could be overridden by hw_trace.
1609
1610 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1611
1612 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1613 debug.c. It could be much simpler.
1614
1615Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
72f4393d 1616
c906108c

1623 (device_find_string_property): Allow a string array.
1624 (device_init_static_properties): Update.
1625 (device_init_runtime_properties): Update.
1626
1627 * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk
1628 media. If no file image is specified, use the next one in the
1629 image property list.
1630 (hw_disk_init_address): Change the file property so that it is a
1631 string array - use the first entry for the initial file image.
1632
1633 * tree.c (print_string_aray_property): New function - print a
1634 string array.
1635 (print_properties): Adjust.
1636 (print_string): Write a string, handling double quotes.

c906108c
SS		 1641 * hw_disk.c: Allow floppy disk devices to be specified.
1642
1643 * psim.c (psim_command): New function, parse more complex psim
1644 commands such as "change-media" and "trace".
1645 * sim_calls.c (sim_do_command): Use.
1646
1647Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1648
1649 * For expressions like (RA == 0) that are entered in to the cache
1650 as RA_is_0. If possible generate the result of the expression so
1651 that the compiler gets a better chance of eliminating dead
1652 branches.
1653
1654 * gen-icache.c (print_icache_extraction): For a cache entry of
1655 the form <name>_is_<const> where it is a boolean field, generate
1656 the result of the expression instead of the expression its self.
1657 (print_icache_body): Remove code that was looking for *_is_0 and
1658 then generating corresponding definitions.
1659
1660 * gen-icache.c (print_icache_struct): If there is no cache, do not
1661 output expressions in idecode.h file.
72f4393d 1662
c906108c 1663 * gen-icache.c (print_icache_body): Output them here.

1670Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1671
1672 * The code that put values in and extracted values from the cache
1673 was too compilicated. The cache table did not allow values to be
1674 computed from cache entries. #defines could only be used when a
1675 cache was present, remove the restriction.
1676
1677 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1678 scratch variable is defined when a cache entry is beinf
1679 filled. Change the definition of a COMPUTE variable to be defined
1680 when the cache entry is being used.

3013 always update the cache_entries semantic and address fields.
3014
3015 * gen-idecode.c (print_idecode_switch_illegal): Include a break

72f4393d
L		 3057 configuration options. Let the user specify the packages or
3058 hardware devices that are to be included in the build. Makes it

c906108c
SS		 3060
3061 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
3062 hardware instead of checking it using ls. configure.in should

3105
3106 * gen-idecode.c: Output the complete run_until_stop function
72f4393d 3107 instead of just the code to handle a single instruction issue.
c906108c
SS		 3108 * : Have the generated idecode.c include inline.c (instead of psim.c).
3109
3110 * std-config.h: Change psim.c so that it isn't inlined (as this is
72f4393d 3111 no longer needed).
c906108c
SS		 3112
3113 * psim.c (run_until_stop): Delete the old run_until_stop function
72f4393d
L		 3114 instead calling the idecode_run and idecode_run_until_stop
3115 functions that gen-idecode.c is now creating.

3150 * gen-idecode.c (print_jump_until_stop_body): New function and
72f4393d
L		 3151 idecode generation option. Instead of generating and calling
