1021
1022 Make the simulator compatible with the MPC750. It would be nicer
1023 to make this a real multi-sim, but that's more work than we have
1024 time for.
1025 * emul_generic.c (emul_add_tree_options): Only require strict
1026 alignment if it was explicitly requested at configuration time.
1027 Don't make it the default for little-endian machines.
1028 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1029 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1030 THRM2, THRM3): Plop in the MPC750 SPR registers.
1031 (DABR): This is weird. This was HID5, but the PPC spec says this
1032 should be DABR; why did some random processor use it for something
1033 else? The HID5 entry dates back to the original checkin of the
1034 simulator code in 1995, so remove it.
1035 * sim_calls.c (register_names): Delete this; since the user can
1036 now change GDB's list of register names dynamically, we can't
1037 pretend there's a static mapping here.
1038 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1039 function to get the register name. That ought to be accurate.
1040 However, we're changing a compile-time dependency (using the
1041 REGISTER_NAMES macro) into a link- and run-time dependency
1042 (calling REGISTER_NAME, which happens to be a function call on the
1043 PPC).
1044
10451999-01-22 Jim Lemke <jlemke@cygnus.com>
1046
1047 * igen.c(gen_semantics_[ch]): setup/use of new option

1075Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1076
1077 * table.c (table_open): For cygwin hosts, we need to use the
1078 return value from the read routine as the number of bytes to
1079 process. This apparently is due to text-mode vs binary-mode. If
1080 the mounts are done text-mode, then the size returnedby fstat()
1081 may be different than the number of bytes "read" in text mode.

1107
1108 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1109 but there was no such target, only plain psim. So I changed the
1110 run target to depend on psim.

72f4393d 1520
c906108c
SS		 1521 * psim.c (psim_write_register, psim_read_register): Force the cpu
1522 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1523 next cpu would be zero any way.
1524
1525 * mon.c (mon_print_info): If possible, print the system cycle
1526 performance. This is an indication of the number of instructions
1527 per second.
1528
1529Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1530
1531 * The code to allow an event queue to be updated during a signal

72f4393d 1534
c906108c
SS		 1535 * The simulation would not correctly restart if an event requested

1587
1588 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1589 to be initialized independant of the rest of the simulation
1590 initalization. Otherwize a trace option explictly set from gdb
1591 could be overridden by hw_trace.
1592
1593 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1594
1595 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,

1631
1632 * For expressions like (RA == 0) that are entered in to the cache
1633 as RA_is_0. If possible generate the result of the expression so
1634 that the compiler gets a better chance of eliminating dead
1635 branches.
1636
1637 * gen-icache.c (print_icache_extraction): For a cache entry of
1638 the form <name>_is_<const> where it is a boolean field, generate
1639 the result of the expression instead of the expression its self.
1640 (print_icache_body): Remove code that was looking for *_is_0 and
1641 then generating corresponding definitions.
1642
1643 * gen-icache.c (print_icache_struct): If there is no cache, do not
1644 output expressions in idecode.h file.

1653Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1654
1655 * The code that put values in and extracted values from the cache
1656 was too compilicated. The cache table did not allow values to be
1657 computed from cache entries. #defines could only be used when a
1658 cache was present, remove the restriction.
1659
1660 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1661 scratch variable is defined when a cache entry is beinf
1662 filled. Change the definition of a COMPUTE variable to be defined
1663 when the cache entry is being used.
1664 * gen-icache.c: Update.
72f4393d 1665
c906108c

2996 always update the cache_entries semantic and address fields.
2997
2998 * gen-idecode.c (print_idecode_switch_illegal): Include a break
2999 when generating illegal instructions. This was commented out
3000 which is a hangover from looking a at switch statements generated
3001 using indirect jumps.
3002
3003Tue Jul 23 20:57:01 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

72f4393d
L		 3040 configuration options. Let the user specify the packages or
3041 hardware devices that are to be included in the build. Makes it

c906108c
SS		 3043
3044 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
3045 hardware instead of checking it using ls. configure.in should

3087Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
3088
3089 * gen-idecode.c: Output the complete run_until_stop function
72f4393d 3090 instead of just the code to handle a single instruction issue.
c906108c
SS		 3091 * : Have the generated idecode.c include inline.c (instead of psim.c).
3092
3093 * std-config.h: Change psim.c so that it isn't inlined (as this is
72f4393d 3094 no longer needed).
c906108c
SS		 3095
3096 * psim.c (run_until_stop): Delete the old run_until_stop function
72f4393d
L		 3097 instead calling the idecode_run and idecode_run_until_stop
3098 functions that gen-idecode.c is now creating.
c906108c

3133 * gen-idecode.c (print_jump_until_stop_body): New function and
72f4393d
L		 3134 idecode generation option. Instead of generating and calling
