6 (gen_model_c): Use strcmp, strcasecmp.
7 (lf_print_c_semantic_function_header): Delete unused function.
9 * main.c (cpu.h): Include cpu.h to get model.h.
11 Mon Nov 13 09:14:13 1995 Michael Meissner <meissner@tiktok.cygnus.com>
13 * igen.c ({insn,model}_table_fields): Spell mnemonic correctly.
14 (gen_itable_h,itable_c_insn): Ditto.
15 (model support): Move model support around, add support for
16 model-data, model-internal. Use annex field for model-macros
19 * configure.in (--enable-sim-inline): If --enable-sim-inline=no,
20 also define INLINE as nothing.
21 * configure: Regenerate.
23 * std-config.h (INLINE): Rather than nuking INLINE, only define it
24 as __inline__ if any of the INLINE flags are non-zero.
26 * options.c (print_options): Print out WITH_XOR_ENDAIN.
28 Mon Nov 13 23:03:45 1995 Andrew Cagney <cagneyhighland.com.au>
30 * ppc-instructions (rfi): Add missing code.
32 * cpu.c (cpu_get_time_base): Fix calculation of current value of
35 * ppc-spr-table (TBL, TBU): Fix TBL/TBU entries - was confusing
36 m[tf]tb with m[tf]spr.
38 * ppc-instructions (mtspr, mfspr): Fix mttbl - wasn't storing
41 Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au>
43 * std-config.h (INLINE, STATIC_INLINE): Was being set to static
44 inline.. Only problem being that with ppc-opcode-simple this gave
45 it the chance to inline all the idecode functions with potentially
46 disasterous results on a 16mb PC. For moment hobble INLINE.
48 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
51 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
52 Firstly make them errors and secondly remove the options gcc-245
55 Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
57 * misc.c (zalloc), cpu.c (cpu_init), devices
58 (console_io_read_buffer_callback, icu_io_read_buffer_callback,
59 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
60 sim_calls.c (zalloc) : replace bzero() with memset().
62 * emul_netbsd.c (write_direntries), psim.c (psim_read_register,
63 psim_write_register): replace bcopy() with memcpy().
65 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
67 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
68 force DEFAULT_INLINE to 0 rather then trusting the std
71 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
73 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
74 generation of switch entries in tables - treat the same as
75 cracking/semantic functions.
77 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
78 of a boolean switch statement (field zero or non-zero).
80 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
81 switch/table generation ability of igen.
83 * igen.c (idecode_switch_leaf): Fix code output when a switch
84 statement needs to look up a table.
86 * igen.c (idecode_declare_if_switch): New function called from
87 gen_idecode_c - need to declare any idecode switch functions
88 before they are used in idecode tables.
90 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
91 idecode_crack_insn): Add is_inline_function argument to code
92 printing cracker functions which indicates if STATIC_IDECODE or
93 STATIC_INLINE_IDECODE should be used for definition. For
94 idecode_crack_insn (which implies not duplicating/expanding) don't
95 declare function as inline - we assume that the only time this is
96 code is generated is when things are being tested. For
97 idecode_crack_leaf, make static (instead of INLINE) if the
98 instructions parent is a table as function will always be called
101 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
102 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
103 called directly, all others are called via a table.
105 * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
106 semantics_h_insn, semantics_h_function,
107 lf_print_c_semantic_function, semantics_c_function): Add
108 is_inline_function argument to lf_print_semantic_function_header
109 to indicate if an inline or static function declaration/definition
110 should be output. Depending on situtation call accordingly:
111 functions (not instruction semantic routines) are always inline;
112 Semantic routines are made inline when there is no icache (cache
113 will contain the function address) and are duplicating (see above)
114 and the parent of the instruction is a switch statement.
116 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
117 and moved to insn_table_find_opcode_field.
119 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
121 * igen.c (model_c_insn): Suggestion - document the name of the
122 instruction on each line of the instruction model table.

126 * emul_netbsd.c (do_ioctl): Cleanup compilation.
128 * sim_callbacks.h (__attribute__): Only define if not defined (was
129 already defined on NetBSD host).

134 macro, indicates if the PowerPC's horrible XOR endian mode should
135 be suported. Add to configure and make.
137 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
138 (vm_instruction_map_read): If XOR endian, xor the address
139 with a value from an xor table (indexed by size of access).
141 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
142 set up xor table to xor if there is a conflict between the
143 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
144 check of suported change of endian mode from cpu.c to vm.c.
146 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
147 Hopefully added correct hack to handle XOR endian mode.
149 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
150 little endian mode, the model accepts miss aligned transfers.
152 FIXME: Need to create an `init' device that, during
153 initializatioin for XOR mode, it mushes (XOR address) all the dma
154 data before passing it on to the core for storage. Just like the
157 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
159 * devices.c (halt_io_write_buffer_callback): Use value written to
160 halt device to determine exit status. Thus allowing
161 success/failure of OEA tests.
163 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au>
165 * ppc-instructions (icbi): If icache present flush it.

177 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
179 * filter_filename.c, Makefile.in: Change so that only dependant on
180 a very limited nr of files. Stops an unnecessary dependency.
182 Tue Nov 7 15:44:33 1995 Andrew Cagney <cagney@highland.com.au>
184 * core.c (core_map_find_mapping): Use cpu_halt rather than error
185 to abort an access to an undefined address.

244 * igen.c (semantics_h_print_function): Emit STATIC_SEMANTICS
245 instead of INLINE_SEMANTICS so that the compiler won't keep all of
246 the semantic functions as inline RTL, given that the address of
247 the function is taken which forces outline calls anyway.

577 instructions nops instead of invalid instructions.
579 * Makefile.in (CONFIG_CFLAGS): Add ALIGNMENT_CFLAGS and
580 TIMEBASE_CFLAGS which weren't included.
582 Thu Nov 2 08:54:04 1995 Michael Meissner <meissner@tiktok.cygnus.com>
584 * Makefile.in: Uncomment built file dependencies.
586 * configure.in: Rewrite --enable-sim switch handling to use the
587 autoconf builtins so it works correctly if the configure or
588 Makefile.in files are modified and make decides to rebuild
589 Makefile. Also document all of the --enable-sim switches
590 supported. Check whether getrusage and sys/resource.h are
592 * config.in: Regenerate.
593 * configure: Regenerate.
594 * Makefile.in: Add support for all of the variables set with
595 --enable-sim switches.
597 * Makefile.in (clean): make clean now removes all built sources as
600 * cpu.c: Use HAVE_STRING_H, HAVE_STRINGS_H, HAVE_UNISTD_H,
601 HAVE_TIME_H, HAVE_SYS_TIMES_H, HAVE_SYS_RESOURCE_H defined in
602 the generated config.h.
604 * device_tree.c: Ditto.
607 * emul_netbsd.c: Ditto.
612 * registers.c: Ditto.
617 * main.c (main): Call psim_print_info with verbose == 2.
619 * mon.c (mon_print_info): Align the cpu number and number of
620 instructions fields. Do not print an instruction category if the
621 CPU did not execute any of those instructions. Print out number
622 of reads and writes. If getrusage is supported, print out number
623 of simulated instructins per second.
625 * configure.in: Add support for --enable-sim-opcode=stupid.
626 * configure: Regenerate.
628 Wed Nov 1 23:46:59 1995 Andrew Cagney <cagney@highland.com.au>
630 * std-config (INLINE_DEVICE_TREE): Don't inline either of
631 device_tree.c or devices.c. There is no significant gain.
633 * configure.in, Makefile.in: add --enable-sim-icache=[0-9]* and
636 Wed Nov 1 23:46:59 1995 Andrew Cagney <cagney@highland.com.au>
638 * igen.c (main), misc.h (target_a2i, i2target), misc.c: Add
639 functions to convert between target and igen internal bit numbers.
640 Make IO go through these functions. Add -b (bit size) and -h (high
641 bit nr) options to igen. Typical usage would be: ./igen -b 16 -h
642 15 for a 16 bit instruction format with the msb given a number 15.
644 Wed Nov 1 22:17:32 1995 Andrew Cagney <cagney@highland.com.au>
646 * dgen.c (main): Was outputting optarg even when it was NULL.
648 Tue Oct 31 23:48:33 1995 Andrew Cagney <cagney@highland.com.au>
650 * vm_n.h (vm_data_map_load_N, vm_data_map_store_n), debug.h,
651 debug.c: Add tracing of load/store unit (virtual) with -t
654 Tue Oct 31 21:44:01 1995 Andrew Cagney <cagney@highland.com.au>
656 * std-config.h (WITH_ENVIRONMENT): Add USER_ENVIRONMENT which does
657 not include things such as the time base and events.
659 * interrupt.c, sim_calls.c, cpu.h, vm.c, configure.in: Add UEA to
660 all environment switches for above.
662 * psim.c (psim_create): ditto - new device tree node name is
663 /options/environment-architecture with values user, virtual and
666 Tue Oct 31 21:31:32 1995 Andrew Cagney <cagney@highland.com.au>
668 * ppc-opcode-stupid: Third example of use of opcode table - this
669 one expands all mtspr/mfspr and branch instructions. Appears to
670 give about a 10% gain in performance if everything enabled. Also
671 takes about 150mb of swap to build.
673 Wed Nov 1 10:49:48 1995 Michael Meissner <meissner@tiktok.cygnus.com>
675 * emul_netbsd.c (do_exit): Print arguments and close parenthesis
676 if tracing, since exit doesn't go through emul_exit_call.
677 (do_read): Print arguments if tracing.
683 (do_sigprocmask): Replace trace with printing arguments if
685 (do_ioctl): Print arguments if tracing.

709 invalid instructions.
711 * configure.in: Add support for more --enable-sim-* switches.
712 Use config.make and config.hdr to write to Makefile and config.h
713 respectively. Don't rewrite Makefile, just append to it.
714 * configure: Regenerate.
715 * config.{make,hdr}: New shell scripts.
717 * Makefile.in: Remove all variables set by configure.in.
718 (psim.o): Depend on $(BUILT_SRC) also.
720 * emul_netbsd.c (do_gettimeofday,do_getrusage): When comparing an
721 integer, use 0, not NULL.

728 and --enable-sim-endian switch to control various Makefile
730 * configure: Regenerate from configure.in.
731 * Makefile.in: Add various Make variables that the various
734 * std-config.h (DEFAULT_INLINE): Don't set this to 2 if using GCC
735 and optimizing by default.
737 Fri Oct 27 19:26:27 1995 Andrew Cagney <cagney@highland.com.au>
739 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
740 make them functions again. Appears 2.6.3 is confused by just a
743 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
745 * ppc-endian.c (SWAP_8): Fix 8 byte swap!
747 * psim.c (psim_create): Not correctly checking that runtime
748 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
749 matched the compiled in ones.
751 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
752 trace_semantics is now different to trace_idecode, the former
755 Tue Oct 24 21:54:13 1995 Andrew Cagney <cagney@highland.com.au>
757 * ppc-instructions (mtsrin): Missing instruction
758 * ppc-instructions (mfsrin): Missing instruction
759 * ppc-instructions (eieio): Missing instruction
761 Tue Oct 24 20:55:29 1995 Andrew Cagney <cagney@highland.com.au>
763 * build-psim: New shell script - see internals for usage,
764 simplifies the process of building custom simulators.
766 Mon Oct 23 23:48:59 1995 Andrew Cagney <cagney@highland.com.au>
768 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
769 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
770 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
771 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
772 the instruction or data critical paths.
774 * FIXME: need to set up OS_EMUL_INLINE/EMUL_GENERIC_INLINE but
775 not on critical path.
777 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
778 the inclusion of device_tree.c/emul_generic.c.
780 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
782 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace
783 system.[hc]. Start of suport for multiple emulations and
784 emulation state (os_emul object).
786 * emul_generic.[hc]: Start of code to implement proper system call
789 Sun Oct 22 21:33:51 1995 Andrew Cagney <cagney@highland.com.au>
791 * cpu.h, cpu.c (cpu_init): New function, zero the registers before
792 the processor is started. Fixes problem of registers being
793 undefined when restarting from within gdb.
795 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
796 instruction cache (if present). Fixes problem of cpu caching gdb
797 breakpoint instructions.
799 FIXME: PSIM sometimes aborts calling error(), it should instead
800 call sim_error() say which takes care of housekeeping such as
801 saving the CIA before calling error.
803 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
804 used when restarting a simulation because the latter has the
805 unwanted side effect (well I as a kernel hacker think it is) of
806 performing an isync when the instruction stream doesn't contain
809 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
811 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
812 monitoring module. Counts both instructions issued and
815 * NOTE: mon does not contain to count instruction loads as this
816 information is already available from the mon_issue() hook.
818 * FIXME: mon doesn't have access to register usage information.
819 This is needed if the user wants to monitor things like register
822 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
824 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
825 a common monitor to each of the cpus. Delete
826 cpu_increment_number_of_insns() and cpu_get_number_of_insns()
827 replaced by copied code in mon.[hc].
829 Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au>
831 * sim_calls.c, main.c, psim.c (psim_create): always create
832 `WITH_SMP' cpus. The actual number of CPU's active in a
833 simulation run is taken from the device node: /init/smp (an
834 integer). WITH_SMP changed to 2 (remember to put it back to 0).
836 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
838 * system.c: More system call emulation. If code appears NetBSD
839 specific, make conditional to being compiled on a NetBSD system
842 Wed Oct 18 23:02:20 1995 Andrew Cagney <cagney@highland.com.au>
844 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
845 lf.[ch](new), table.[ch](new): Split into two generators - igen
846 that outputs the instruction tables and dgen that outputs the spr
847 tables. Add -f (filter out) flag to igen to filter out certain
848 instructions (ex 64 bit ones) from the created tables. Include
849 $(LIBIBERTY_LIB) in link options in case host lacks some libc
852 * NOTE: igen, since it was originally written for the
853 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
855 * Makefile.in, std-config.h, ppc-cache-rules(new),
856 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
857 cache-rule and opcode-rule tables from macros found std-config.h.
858 Delete corresponding macro's from std-config.h.
860 * FIXME: under this new igen scheme, when playing around with igen
861 options, you'll find that depenencies don't work very well.
863 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
864 an table of all the instructions. Code to output a type
865 enumerating all the instructin names.
867 * igen.c(lf_print_c_semantic): Move call to increment instruction
868 counter so that it occures _after_ the instruction has been fully
869 validated, was double counting illegal/invalid instructions. Add
870 conditional so only compiled in when WITH_PROFILE enabled (enabled
873 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
874 itable.h, count individual instruction types not just total,
875 adjust reporting functions to output this.
877 * ppc-instructions (64 bit Load Doubleword with Update Indexed):
878 Had 32./ instead of 31./
880 * ppc-instructions (64 bit Store Double Word Conditional Indexed):
881 bitrot - updated to use newer CR register operators.
883 * ppc-instructions (64bit Floating Convert from Integer
884 Doubleword): Correct call to Round_Float().
886 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
888 * basics.h: #include "sim_callbacks.h" earlier so that its
889 prototypes are declared in all other header files.
891 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
892 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into
895 * FIXME: the bits.h/bits.c macro's should be replaced with
896 (inline) c functions.
898 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
899 Add size of buffer argument to functions writing a string into a
900 buffer. Check for buffer overflow.
902 Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au>
904 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing
905 of each device. Make parameter names consistent so macros work.
906 Use macro's in device functions.
908 * device_tree.c, devices.h, devices.c: include path to device in a
909 devices node when creating it.
911 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.
913 * core.c: add tracing of core-device, adjust parameter names in
914 core functions to be consistent with those in devices*.
916 Sun Oct 15 20:33:20 1995 Andrew Cagney <cagney@highland.com.au>
918 * debug.h, debug.c (trace_option): New function. Parses the trace
919 option, updating the trace array.
921 * debug.h, debug.c (trace_usage): New function. Outputs the list
922 of all possible trace options.
924 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
925 parse trace options specified with the simpler -t flag. Adjust
928 * FIXME: basic parsing of command line options is still duplicated
929 by main.c and sim_calls.c
931 Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com>
933 * Makefile.in (clean): Delete *.i and *.out files.
935 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
936 macros for either assignment or return. Fix SWAP_8 to use a
937 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
938 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
939 that hardwired swapping on/off, let optimizer delete dead code.
941 * main.c (main): Add printf that we caught a signal and print out
944 Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com>
946 * Makefile.in: Remove tabs from otherwise empty line.
947 Confuses many non-GNU versions of "make".
949 Wed Oct 18 08:51:25 1995 Michael Meissner <meissner@tiktok.cygnus.com>
951 * Makefile.in (clean): Delete files produced by gen.
953 Mon Oct 16 17:34:24 1995 Michael Meissner <meissner@tiktok.cygnus.com>
955 * gen.c (lf_print_c_semantic_function): Move counting # of
956 instructions here so it works with caching.
957 (gen_idecode_c): Move from here.
959 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
961 * gen.c, ppc-instructions, psim.c: Fix code for generating
962 cracking instruction cache. Delete the code that cached just the
963 result from doing an instruction lookup - this ran slower than no
966 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
968 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
970 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
971 TCL when gdb is linked with the simulator.
972 * debug.c (ppc_trace): Ditto.
973 * sim_calls.c (sim_open): Change trace -> ppc_trace.
974 * main.c (main): Ditto.
976 * cpu.c (cpu_add_commas): Remove extra static.
978 Thu Oct 12 11:35:53 1995 Michael Meissner <meissner@tiktok.cygnus.com>
980 * Makefile.in (psim.o): Now that inlines are turned on, make
981 psim.o depend on all sources.
983 * cpu.c (cpu_add_commas): New function to format a long with
985 (cpu_print_info): Use it to print number_of_insns.
987 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
989 (ENDIAN_N): If both target and host byte orders are known, don't
990 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
992 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
993 to allow target specific H2T_n/T2H_n macros to be used.
994 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
995 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
996 of the 3 instruction sequence that runs on 386s.
998 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
999 specified on the compile line.
1000 (WITH_BSWAP): If not defined, define as 0.
1002 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
1003 default inline support. Pass INLINE_CFLAGS when compiling.
1005 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
1006 INLINE_DEVICES since GCC doesn't like inline functions that
1007 accept variable arguments.
1008 (stack_ioctl_callback): Make function just static because GCC
1009 doesn't like inline functions that accept variable arguments.
1011 * devices.h (STATIC_DEVICES): Define as empty if not defined.
1013 * inline.c: Correct pathnames of included C files to match current
1016 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
1017 non-zero, define STATIC_DEVICES to be static.
1019 * std-config.h (INLINE): If GNU C and optimizing, define this as
1021 (DEFAULT_INLINE): If not defined, define as 0.
1022 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
1023 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
1024 ({SPREG,IDECODE}_INLINE): Ditto.
1026 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1028 * ppc-instructions: Initial cut of floating point suport added.
1029 Of note include - use of host IEEE floating point instructions,
1030 use of PowerPC manual pseudo code to handle the FPSCR. It is not
1031 currently a pretty sight.
1033 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
1034 merge into core.h, core.c, core_n.h. The type memory_map replaced
1035 with core_map. This removes a level of pointer indirection when
1036 translating an address.
1038 * memory_map.h, memory_map.c, memory_map_n.h: delete.
1040 * Makefile.in et.al (sorry): tweek to use new core, core_map and
1043 Wed Oct 11 12:10:26 1995 Andrew Cagney <cagney@highland.com.au>
1045 * sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to
1046 most of the other functions in sim_calls.c.
1048 * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
1049 Add macros to better cover up `generic' code. Makes it possible
1050 to step through the generic code!
1052 * vm.c, vm_n.h, Makefile.in: ditto
1054 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
1056 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
1057 callback interface so that there is a read/write buffer but no
1058 read/write_word. VEA default memory read/write handler sometimes
1059 couldn't resolve an access and of those some were for a memory
1060 fault and some were because gdb was making a bogus request.
1062 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
1063 eliminate transfer_mode (raw or cooked) parameter from read/write
1066 Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au>
1068 * ppc-instructions (fmul, fmuls): correct instruction format - had
1071 Wed Oct 4 17:31:12 1995 Andrew Cagney <cagney@highland.com.au>
1073 * psim.c, device_tree.h, device_tree.c, devices.c (printd_*,
1074 scand_*): new functions to parse/print fields in device names
1075 while hiding any machine dependency.
1077 * devices.c, psim.c: Change the stack init code so that it is
1078 handled by a device. Arguments passed across using a device ioctl
1081 * devices.h, devices.c: device ioctl callback changed to allow a
1082 variable number of arguments. This gives greater flexability and
1083 greater chance of bugs.
1085 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
1087 * main.c (printf_filtered, error): Missing va_end() to close off
1088 variable argument use.
1090 * Makefile.in (tmp-gencode): comment out hack to get around some
1091 versions of make not handling files being created as side-effects.
1093 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
1094 alternative file name to use in output files for things like #line
1097 Makefile.in (tmp-gencode): Use gen -n so that debug info is
1100 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the
1103 Sat Oct 7 22:40:59 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1105 * sim_calls.c (sim_set_callbacks): Define new function.
1107 Fri Oct 6 17:23:10 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1109 * psim.c (psim_print_info): Print exit status or signal number.
1111 Mon Oct 2 11:46:37 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1113 * cpu.c (struct _cpu): Add number_of_insns field to trace how many
1114 instructions are executed.
1115 (cpu_increment_number_of_insns): New function to increment the
1116 number of instructions issued.

1297 everything lives in the one directory. While a pain for cleaning,
1298 makes building across multiple architectures much simpler.
1300 * devices.c, device_tree.c: Added code that provides a simple
1301 illustration of how an interrupt control device could be
1304 * devices.c: Added code so that the dumb console device can read
1305 (from stdin) as well as write to stdout.
