1025
1026 Make the simulator compatible with the MPC750. It would be nicer
1027 to make this a real multi-sim, but that's more work than we have
1028 time for.
1029 * emul_generic.c (emul_add_tree_options): Only require strict
1030 alignment if it was explicitly requested at configuration time.
1031 Don't make it the default for little-endian machines.
1032 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1033 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1034 THRM2, THRM3): Plop in the MPC750 SPR registers.
1035 (DABR): This is weird. This was HID5, but the PPC spec says this
1036 should be DABR; why did some random processor use it for something
1037 else? The HID5 entry dates back to the original checkin of the
1038 simulator code in 1995, so remove it.
1039 * sim_calls.c (register_names): Delete this; since the user can
1040 now change GDB's list of register names dynamically, we can't
1041 pretend there's a static mapping here.
1042 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1043 function to get the register name. That ought to be accurate.
1044 However, we're changing a compile-time dependency (using the
1045 REGISTER_NAMES macro) into a link- and run-time dependency
1046 (calling REGISTER_NAME, which happens to be a function call on the
1047 PPC).
1048
10491999-01-22 Jim Lemke <jlemke@cygnus.com>
1050

1079Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1080
1081 * table.c (table_open): For cygwin hosts, we need to use the
1082 return value from the read routine as the number of bytes to
1083 process. This apparently is due to text-mode vs binary-mode. If
1084 the mounts are done text-mode, then the size returnedby fstat()
1085 may be different than the number of bytes "read" in text mode.

1110Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1111
1112 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1113 but there was no such target, only plain psim. So I changed the
1114 run target to depend on psim.
1115
1116Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>

1459 works for normal and boolean table entries.
1460
1461 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
1462 valid. Handle this just like *_{read,write}_register now handles

1477
1478 * gen-idecode.c: Re-work the table lookup code so that it assumes
1479 that the entry is a leaf by default. Simplify the boolean table
1480 entry code so that it involves a mask + test instead of shift +
1481 shift + mask + test.

1522 determine the simulation speed by looking at the number of elapsed
1523 ticks recorded by the event queue.
72f4393d 1524
c906108c
SS		 1525 * psim.c (psim_write_register, psim_read_register): Force the cpu
1526 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1527 next cpu would be zero any way.
1528
1529 * mon.c (mon_print_info): If possible, print the system cycle
1530 performance. This is an indication of the number of instructions
1531 per second.
1532
1533Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1534
1535 * The code to allow an event queue to be updated during a signal
1536 was missing. For main.c, a cntrl-c simulation termination wasn't
1537 handled cleanly.
72f4393d 1538
c906108c
SS		 1539 * The simulation would not correctly restart if an event requested

72f4393d 1541
c906108c
SS		 1542 * psim.c (psim_options): Add hack to -i option to optionally

1556 the processing state when processing has started. Adjust code
1557 so that it is tolerant of halts.
1558 (event_queue_init): Start the event queue out with processing
1559 false.
1560 (event_queue_tick): Check that processing isn't still being
1561 performed.
72f4393d 1562
c906108c
SS		 1563 * gen-idecode.c (print_run_until_stop_body): Call
1564 event_queue_process_events to clear possibly pending events before
1565 starting a simulation run. Re-arange main loop so that simulator

1573
1574 * ppc-opcode-complex: Correct typo - was expanding ORA instead of

72f4393d 1578
c906108c

SS		 1590Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1591
1592 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1593 to be initialized independant of the rest of the simulation
1594 initalization. Otherwize a trace option explictly set from gdb
1595 could be overridden by hw_trace.
1596
1597 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1598
1599 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,

72f4393d 1603

1612 (device_init_runtime_properties): Update.
1613

1618 string array - use the first entry for the initial file image.
1619
1620 * tree.c (print_string_aray_property): New function - print a
1621 string array.
1622 (print_properties): Adjust.

1633
1634Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1635
1636 * For expressions like (RA == 0) that are entered in to the cache
1637 as RA_is_0. If possible generate the result of the expression so
1638 that the compiler gets a better chance of eliminating dead
1639 branches.
1640
1641 * gen-icache.c (print_icache_extraction): For a cache entry of
1642 the form <name>_is_<const> where it is a boolean field, generate
1643 the result of the expression instead of the expression its self.
1644 (print_icache_body): Remove code that was looking for *_is_0 and
1645 then generating corresponding definitions.
1646
1647 * gen-icache.c (print_icache_struct): If there is no cache, do not
1648 output expressions in idecode.h file.
72f4393d 1649

1657Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1658
1659 * The code that put values in and extracted values from the cache
1660 was too compilicated. The cache table did not allow values to be
1661 computed from cache entries. #defines could only be used when a
1662 cache was present, remove the restriction.
1663
1664 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1665 scratch variable is defined when a cache entry is beinf
1666 filled. Change the definition of a COMPUTE variable to be defined
1667 when the cache entry is being used.
1668 * gen-icache.c: Update.
72f4393d 1669
c906108c
SS		 1670 * ld-cache.h, ld-cache.c: Change field names so that their meaning

c906108c
SS		 1674 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1675 different types of cache code - put into cache, extract from
1676 cache, no cache - an explicit argument to print_icache_body.
1677 * gen-icache.c (print_icache_extraction): Ditto.

c906108c
SS		 3047
3048 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and

c906108c
SS		 3095 * : Have the generated idecode.c include inline.c (instead of psim.c).
3096
3097 * std-config.h: Change psim.c so that it isn't inlined (as this is

72f4393d
L		 3138 idecode generation option. Instead of generating and calling

72f4393d
L		 4054 value in the device tree. Options are now first entered into a

4056 greater flexability in configuration.
c906108c
SS		 4057
4058 * psim.c (psim_tree): Returns a basic device tree ready for

4078 created from it.
c906108c
SS		 4079
4080 * psim.c (psim_create): Update to handle above way of creating
72f4393d 4081 things. Extract all information from the device tree.

4101 device tree load from file code.
c906108c
SS		 4102
4103 * psim.c (psim_create): Dump device tree if enabled. If nump

4120
4121 * device.c (attach_device_interrupt_edge): New. Interrupt model
72f4393d
L		 4122 did not allow interrupts to be wired up as a general net (edges).
4123 Re-implement so that interrupt events can be passed to multiple
4124 controllers and interrupt controllers can further propogate
4125 interrupt events.

72f4393d
L		 4150 standard mapping between a devices internal representation (a
4151 pointer) and its external (or what is passed to a client)
4152 representation (a phandle). Implement using the cap object
4153 attached to the root node.

4177 read/write calls for buffer transfers. This will cause a fault to
4178 occure if the transfer fails. CHRP catches the fault while the
4179 others suffer the consequences.
