754 Make the simulator compatible with the MPC750. It would be nicer
755 to make this a real multi-sim, but that's more work than we have
756 time for.
757 * emul_generic.c (emul_add_tree_options): Only require strict
758 alignment if it was explicitly requested at configuration time.
759 Don't make it the default for little-endian machines.
760 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
761 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
762 THRM2, THRM3): Plop in the MPC750 SPR registers.
763 (DABR): This is weird. This was HID5, but the PPC spec says this
764 should be DABR; why did some random processor use it for something
765 else? The HID5 entry dates back to the original checkin of the
766 simulator code in 1995, so remove it.
767 * sim_calls.c (register_names): Delete this; since the user can
768 now change GDB's list of register names dynamically, we can't
769 pretend there's a static mapping here.
770 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
771 function to get the register name. That ought to be accurate.
772 However, we're changing a compile-time dependency (using the
773 REGISTER_NAMES macro) into a link- and run-time dependency
774 (calling REGISTER_NAME, which happens to be a function call on the
775 PPC).

808
809 * table.c (table_open): For cygwin hosts, we need to use the
810 return value from the read routine as the number of bytes to
811 process. This apparently is due to text-mode vs binary-mode. If
812 the mounts are done text-mode, then the size returnedby fstat()
813 may be different than the number of bytes "read" in text mode.

1306
1307 * ppc-opcode-stupid: Move all but the basic table in -complex into
1308 here. Update to new format.
1309
1310 * Makefile.in (tmp-defines): New target. Force defines.h to always
1311 be built. Hence get ppc-opcode-goto to build.
1312
1313Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1317
1318Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1319
1320 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1321 to be initialized independant of the rest of the simulation
1322 initalization. Otherwize a trace option explictly set from gdb
1323 could be overridden by hw_trace.
1324
1325 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1326
1327 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1328 debug.c. It could be much simpler.
1329
1330Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1331
1332 * Some devices support removable media. Add hooks to the disk

1346 string array - use the first entry for the initial file image.
1347

1367 branches.
1368
1369 * gen-icache.c (print_icache_extraction): For a cache entry of
1370 the form <name>_is_<const> where it is a boolean field, generate
1371 the result of the expression instead of the expression its self.
1372 (print_icache_body): Remove code that was looking for *_is_0 and

1385Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1386
1387 * The code that put values in and extracted values from the cache
1388 was too compilicated. The cache table did not allow values to be
1389 computed from cache entries. #defines could only be used when a
1390 cache was present, remove the restriction.
1391
1392 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1393 scratch variable is defined when a cache entry is beinf
1394 filled. Change the definition of a COMPUTE variable to be defined
1395 when the cache entry is being used.
1396 * gen-icache.c: Update.
1397

1401
1402 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1403 different types of cache code - put into cache, extract from
1404 cache, no cache - an explicit argument to print_icache_body.

1406
1407 * gen-semantics.c (print_c_semantic): Update use.

1412 cache.
1413
1414 * configure.in (enable-sim-icache): Clarify description. Make
1415 #define one of the defaults regardless of the cache. Probably
1416 should revamp and add a separate option.
1417

1429
1430 * The cap object was retaining a reference to the instance of a
1431 device after it was deleted. Instead add and remove cap's from the
1432 cap db as they are created and deleted. This ensuring that a
1433 capibility is only used during the lifetime of the corresponding
1434 object.
1435
1436 * cap.h, cap.c: Correct cap type - was signed32 should be
1437 signed_cell.
1438
1439 * cap.c (cap_add, cap_remove): New methods for cap object that
1440 allow the explicit addition and removal of internal objects that
1441 the cap knows about.
1442

1470 size as arguments. These may be multi cell values. Initially fix
1471 the memory code so that they check/detect this. Leave the
1472 adjustment of any clients to later.

2645
2646 * gen-idecode.c (print_jump): Was always generating a jump back to
2647 idecode. Only necessary at tail of semantic code.
2648 (print_jump): Was always setting the processor's cia, even during
2649 startup when the processor was still undefined.
2650 (print_jump): For safety, restart smp loop when cpu_nr >= nr_cpus,

2694
2695 * std-config.h (SEMANTICS_INLINE): By default, mask out the
2696 inlining of semantic functions from DEFAULT_INLINE. Almost all
2697 configurations call the semantic code via a pointer so there is
2698 little benefit.
2699

2701
2702Thu Jul 25 20:07:30 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

2726
2727 * gen-icache.c (print_icache_function): Have the cache function
2728 always update the cache_entries semantic and address fields.
2729
2730 * gen-idecode.c (print_idecode_switch_illegal): Include a break
2731 when generating illegal instructions. This was commented out
2732 which is a hangover from looking a at switch statements generated
2733 using indirect jumps.
2734
2735Tue Jul 23 20:57:01 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

2744 support.h so that, like cpu, it is optionally inlined for all
2745 modules that include it.
2746 * inline.h, inline.c: Adjust so that support.[hc] is handled the
2747 same as cpu.[hc].
2748
2749 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2750 name for a lable and then branch to it.
2751
2752 * ppc-instructions (convert_to_integer, Floating Round to
2753 Single-Precision, Floating Convert from Integer Doubleword): Use
2754 LABEL and GOTO instead of the recently added switch statements.
2755
2756Wed Jul 24 14:02:42 1996 Andrew Cagney <cagney@sawnoff.highland.com.au>
2757
2758 * gen-idecode.c (print_run_until_stop_body): Too many rparen in

2774 possible for user packages to be specified.
2775
2776 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
2777 hardware instead of checking it using ls. configure.in should
2778 have taken care of any problems.
2779 (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
2780
2781Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
2782
2783 * psim.c (psim_options): Enter the argument to the memory size
2784 option directly into the device tree. Was using atol() which is
2785 dangerously non portable.
2786

2788
2789 * configure.in (icache): Extend icache flag to include an insn

2806Mon Jul 22 20:00:25 1996 Andrew Cagney <cagney@highland.com.au>
2807
2808 * emul_generic.c (emul_add_tree_options): Was incorrectly setting
2809 the strict-alignment option when hardwired for non-strict
2810 alignment.
2811
2812Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2813
2814 * gen-semantics.c: Make the my_index variable a macro MY_INDEX.

2820
2821 * gen-idecode.c: Output the complete run_until_stop function

2823 * : Have the generated idecode.c include inline.c (instead of psim.c).
2824
2825 * std-config.h: Change psim.c so that it isn't inlined (as this is
2826 no longer needed).
2827
2828 * psim.c (run_until_stop): Delete the old run_until_stop function
2829 instead calling the idecode_run and idecode_run_until_stop
2830 functions that gen-idecode.c is now creating.

2857 corresponding call to ITRACE so that it still matches.
2858
2859 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead

2864
2865 * gen-idecode.c (print_jump_until_stop_body): New function and
2866 idecode generation option. Instead of generating and calling

2880 testing jumping idecodes.
2881

2889
2890 * configure.in (--enable-sim-icache): Accept an option list such
2891 as 1024,define. Add a new choice to the list - semantic - which
2892 will cause igen to generate instruction decode functions that
2893 include the corresponding semantic code.
2894
2895Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2896
2897 * configure.in: New option --enable-sim-line-nr (default enabled).

2913 * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
2914 that they use the same technique as igen (ie a dummy targets
2915 tmp-pk and tmp-hw are created).
2916
2917Mon Jun 24 22:28:00 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2918
2919 * Makefile.in (BUILD_CFLAGS): Include WARNING_CFLAGS.

3029 core object.
3030
