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

800
801 * table.c (table_open): For cygwin hosts, we need to use the
802 return value from the read routine as the number of bytes to
803 process. This apparently is due to text-mode vs binary-mode. If
804 the mounts are done text-mode, then the size returnedby fstat()
805 may be different than the number of bytes "read" in text mode.

1298
1299 * ppc-opcode-stupid: Move all but the basic table in -complex into
1300 here. Update to new format.
1301
1302 * Makefile.in (tmp-defines): New target. Force defines.h to always
1303 be built. Hence get ppc-opcode-goto to build.
1304
1305Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1310Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1311
1312 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1313 to be initialized independant of the rest of the simulation
1314 initalization. Otherwize a trace option explictly set from gdb
1315 could be overridden by hw_trace.
1316
1317 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1318
1319 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1320 debug.c. It could be much simpler.
1321
1322Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1323
1324 * Some devices support removable media. Add hooks to the disk

1338 string array - use the first entry for the initial file image.
1339

1355
1356 * For expressions like (RA == 0) that are entered in to the cache
1357 as RA_is_0. If possible generate the result of the expression so
1358 that the compiler gets a better chance of eliminating dead
1359 branches.
1360
1361 * gen-icache.c (print_icache_extraction): For a cache entry of
1362 the form <name>_is_<const> where it is a boolean field, generate
1363 the result of the expression instead of the expression its self.
1364 (print_icache_body): Remove code that was looking for *_is_0 and
1365 then generating corresponding definitions.

1377Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1378
1379 * The code that put values in and extracted values from the cache
1380 was too compilicated. The cache table did not allow values to be
1381 computed from cache entries. #defines could only be used when a
1382 cache was present, remove the restriction.
1383
1384 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1385 scratch variable is defined when a cache entry is beinf
1386 filled. Change the definition of a COMPUTE variable to be defined
1387 when the cache entry is being used.
1388 * gen-icache.c: Update.
1389
1390 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1393
1394 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1395 different types of cache code - put into cache, extract from
1396 cache, no cache - an explicit argument to print_icache_body.

1398
1399 * gen-semantics.c (print_c_semantic): Update use.

1404 cache.
1405
1406 * configure.in (enable-sim-icache): Clarify description. Make
1407 #define one of the defaults regardless of the cache. Probably
1408 should revamp and add a separate option.
1409

1421
1422 * The cap object was retaining a reference to the instance of a
1423 device after it was deleted. Instead add and remove cap's from the
1424 cap db as they are created and deleted. This ensuring that a
1425 capibility is only used during the lifetime of the corresponding
1426 object.
1427
1428 * cap.h, cap.c: Correct cap type - was signed32 should be
1429 signed_cell.
1430
1431 * cap.c (cap_add, cap_remove): New methods for cap object that
1432 allow the explicit addition and removal of internal objects that
1433 the cap knows about.
1434
1435 * cap.c (cap_init): Rewrite. Verify that the only objects
1436 remaining in the cap data base are those that were entered first.
1437 Thse objects will be the permenant ones.

1462 size as arguments. These may be multi cell values. Initially fix
1463 the memory code so that they check/detect this. Leave the
1464 adjustment of any clients to later.

2637
2638 * gen-idecode.c (print_jump): Was always generating a jump back to
2639 idecode. Only necessary at tail of semantic code.
2640 (print_jump): Was always setting the processor's cia, even during
2641 startup when the processor was still undefined.
2642 (print_jump): For safety, restart smp loop when cpu_nr >= nr_cpus,
2643 not just equal.
2644

2652
2653 * ppc-cache-rules (cache): Change RS and RB to cache instead of

2686
2687 * std-config.h (SEMANTICS_INLINE): By default, mask out the
2688 inlining of semantic functions from DEFAULT_INLINE. Almost all
2689 configurations call the semantic code via a pointer so there is
2690 little benefit.
2691
2692 * std-config.h (ICACHE_INLINE): Ditto.
2693
2694Thu Jul 25 20:07:30 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

2711 dump.
2712
2713 * gen-idecode.c (print_run_until_stop_body): Only generate loop

2717Wed Jul 24 15:47:09 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2718
2719 * gen-icache.c (print_icache_function): Have the cache function
2720 always update the cache_entries semantic and address fields.
2721
2722 * gen-idecode.c (print_idecode_switch_illegal): Include a break
2723 when generating illegal instructions. This was commented out
2724 which is a hangover from looking a at switch statements generated
2725 using indirect jumps.
2726
2727Tue Jul 23 20:57:01 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

2736 support.h so that, like cpu, it is optionally inlined for all
2737 modules that include it.
2738 * inline.h, inline.c: Adjust so that support.[hc] is handled the
2739 same as cpu.[hc].
2740
2741 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2742 name for a lable and then branch to it.
2743
2744 * ppc-instructions (convert_to_integer, Floating Round to
2745 Single-Precision, Floating Convert from Integer Doubleword): Use
2746 LABEL and GOTO instead of the recently added switch statements.
2747
2748Wed Jul 24 14:02:42 1996 Andrew Cagney <cagney@sawnoff.highland.com.au>
2749
2750 * gen-idecode.c (print_run_until_stop_body): Too many rparen in

2764 configuration options. Let the user specify the packages or
2765 hardware devices that are to be included in the build. Makes it
2766 possible for user packages to be specified.
2767
2768 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
2769 hardware instead of checking it using ls. configure.in should
2770 have taken care of any problems.
2771 (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
2772
2773Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
2774
2775 * psim.c (psim_options): Enter the argument to the memory size
2776 option directly into the device tree. Was using atol() which is
2777 dangerously non portable.
2778

2780
2781 * configure.in (icache): Extend icache flag to include an insn

2796 generators.
2797
2798Mon Jul 22 20:00:25 1996 Andrew Cagney <cagney@highland.com.au>
2799
2800 * emul_generic.c (emul_add_tree_options): Was incorrectly setting
2801 the strict-alignment option when hardwired for non-strict
2802 alignment.
2803
2804Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2805
2806 * gen-semantics.c: Make the my_index variable a macro MY_INDEX.

2812
2813 * gen-idecode.c: Output the complete run_until_stop function
2814 instead of just the code to handle a single instruction issue.
2815 * : Have the generated idecode.c include inline.c (instead of psim.c).
2816
2817 * std-config.h: Change psim.c so that it isn't inlined (as this is
2818 no longer needed).
2819
2820 * psim.c (run_until_stop): Delete the old run_until_stop function
2821 instead calling the idecode_run and idecode_run_until_stop
2822 functions that gen-idecode.c is now creating.
2823
2824Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2825
2826 * dgen.c: Maintenance - update to use new features found in lf.c.

2849 corresponding call to ITRACE so that it still matches.
2850
2851 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
2852 of ITRACE. The CPP line directives would have previously set the
2853 line-nr and file name so ITRACE isn't needed.

2856
2857 * gen-idecode.c (print_jump_until_stop_body): New function and
2858 idecode generation option. Instead of generating and calling

2864
2865 * configure.in: New option --enable-sim-jump (default disabled)

2872 testing jumping idecodes.
2873

2880 decode functions.
2881
2882 * configure.in (--enable-sim-icache): Accept an option list such
2883 as 1024,define. Add a new choice to the list - semantic - which
2884 will cause igen to generate instruction decode functions that
2885 include the corresponding semantic code.
2886
2887Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2888
2889 * configure.in: New option --enable-sim-line-nr (default enabled).
2890 Enable/disable the inclusion of CPP line directives in the
2891 generated files. Such directives refer back to the source files
2892 used when generating the simulator code.

2904
2905 * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
2906 that they use the same technique as igen (ie a dummy targets
2907 tmp-pk and tmp-hw are created).
2908
2909Mon Jun 24 22:28:00 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2910
2911 * Makefile.in (BUILD_CFLAGS): Include WARNING_CFLAGS.

3021 core object.
3022
