1 Tue Nov 14 04:47:25 1995 Michael Meissner <meissner@tiktok.cygnus.com>
3 * Makefile.in (devices.o): Update dependency.
5 * igen.c (gen_model_h): Use correct variable in loop.
6 (lf_print_c_semantic_function_header): Delete unused function.
8 Mon Nov 13 09:14:13 1995 Michael Meissner <meissner@tiktok.cygnus.com>
10 * igen.c ({insn,model}_table_fields): Spell mnemonic correctly.
11 (gen_itable_h,itable_c_insn): Ditto.
12 (model support): Move model support around, add support for
13 model-data, model-internal. Use annex field for model-macros
16 * configure.in (--enable-sim-inline): If --enable-sim-inline=no,
17 also define INLINE as nothing.
18 * configure: Regenerate.
20 * std-config.h (INLINE): Rather than nuking INLINE, only define it
21 as __inline__ if any of the INLINE flags are non-zero.
23 * options.c (print_options): Print out WITH_XOR_ENDAIN.
25 Mon Nov 13 23:03:45 1995 Andrew Cagney <cagneyhighland.com.au>
27 * ppc-instructions (rfi): Add missing code.
29 * cpu.c (cpu_get_time_base): Fix calculation of current value of
32 * ppc-spr-table (TBL, TBU): Fix TBL/TBU entries - was confusing
33 m[tf]tb with m[tf]spr.
35 * ppc-instructions (mtspr, mfspr): Fix mttbl - wasn't storing
38 Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au>
40 * std-config.h (INLINE, STATIC_INLINE): Was being set to static
41 inline.. Only problem being that with ppc-opcode-simple this gave
42 it the chance to inline all the idecode functions with potentially
43 disasterous results on a 16mb PC. For moment hobble INLINE.
45 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
48 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
49 Firstly make them errors and secondly remove the options gcc-245
52 Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
54 * misc.c (zalloc), cpu.c (cpu_init), devices
55 (console_io_read_buffer_callback, icu_io_read_buffer_callback,
56 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
57 sim_calls.c (zalloc) : replace bzero() with memset().
59 * emul_netbsd.c (write_direntries), psim.c (psim_read_register,
60 psim_write_register): replace bcopy() with memcpy().
62 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
64 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
65 force DEFAULT_INLINE to 0 rather then trusting the std
68 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
70 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
71 generation of switch entries in tables - treat the same as
72 cracking/semantic functions.
74 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
75 of a boolean switch statement (field zero or non-zero).
77 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
78 switch/table generation ability of igen.
80 * igen.c (idecode_switch_leaf): Fix code output when a switch
81 statement needs to look up a table.
83 * igen.c (idecode_declare_if_switch): New function called from
84 gen_idecode_c - need to declare any idecode switch functions
85 before they are used in idecode tables.
87 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
88 idecode_crack_insn): Add is_inline_function argument to code
89 printing cracker functions which indicates if STATIC_IDECODE or
90 STATIC_INLINE_IDECODE should be used for definition. For
91 idecode_crack_insn (which implies not duplicating/expanding) don't
92 declare function as inline - we assume that the only time this is
93 code is generated is when things are being tested. For
94 idecode_crack_leaf, make static (instead of INLINE) if the
95 instructions parent is a table as function will always be called
98 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
99 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
100 called directly, all others are called via a table.
102 * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
103 semantics_h_insn, semantics_h_function,
104 lf_print_c_semantic_function, semantics_c_function): Add
105 is_inline_function argument to lf_print_semantic_function_header
106 to indicate if an inline or static function declaration/definition
107 should be output. Depending on situtation call accordingly:
108 functions (not instruction semantic routines) are always inline;
109 Semantic routines are made inline when there is no icache (cache
110 will contain the function address) and are duplicating (see above)
111 and the parent of the instruction is a switch statement.
113 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
114 and moved to insn_table_find_opcode_field.
116 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
118 * igen.c (model_c_insn): Suggestion - document the name of the
119 instruction on each line of the instruction model table.
121 Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au>
123 * emul_netbsd.c (do_ioctl): Cleanup compilation.
125 * sim_callbacks.h (__attribute__): Only define if not defined (was
126 already defined on NetBSD host).
128 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>

131 macro, indicates if the PowerPC's horrible XOR endian mode should
132 be suported. Add to configure and make.
134 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
135 (vm_instruction_map_read): If XOR endian, xor the address
136 with a value from an xor table (indexed by size of access).
138 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
139 set up xor table to xor if there is a conflict between the
140 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
141 check of suported change of endian mode from cpu.c to vm.c.
143 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
144 Hopefully added correct hack to handle XOR endian mode.
146 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
147 little endian mode, the model accepts miss aligned transfers.
149 FIXME: Need to create an `init' device that, during
150 initializatioin for XOR mode, it mushes (XOR address) all the dma
151 data before passing it on to the core for storage. Just like the
154 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
156 * devices.c (halt_io_write_buffer_callback): Use value written to
157 halt device to determine exit status. Thus allowing
158 success/failure of OEA tests.
160 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au>
162 * ppc-instructions (icbi): If icache present flush it.
164 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
166 * devices.c (htab_init_callback): Add code to create htab/pte.

174 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
176 * filter_filename.c, Makefile.in: Change so that only dependant on
177 a very limited nr of files. Stops an unnecessary dependency.
179 Tue Nov 7 15:44:33 1995 Andrew Cagney <cagney@highland.com.au>
181 * core.c (core_map_find_mapping): Use cpu_halt rather than error
182 to abort an access to an undefined address.
184 Sun Nov 12 07:58:09 1995 Michael Meissner <meissner@tiktok.cygnus.com>

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

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

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

725 and --enable-sim-endian switch to control various Makefile
727 * configure: Regenerate from configure.in.
728 * Makefile.in: Add various Make variables that the various
731 * std-config.h (DEFAULT_INLINE): Don't set this to 2 if using GCC
732 and optimizing by default.
734 Fri Oct 27 19:26:27 1995 Andrew Cagney <cagney@highland.com.au>
736 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
737 make them functions again. Appears 2.6.3 is confused by just a
740 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
742 * ppc-endian.c (SWAP_8): Fix 8 byte swap!
744 * psim.c (psim_create): Not correctly checking that runtime
745 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
746 matched the compiled in ones.
748 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
749 trace_semantics is now different to trace_idecode, the former
752 Tue Oct 24 21:54:13 1995 Andrew Cagney <cagney@highland.com.au>
754 * ppc-instructions (mtsrin): Missing instruction
755 * ppc-instructions (mfsrin): Missing instruction
756 * ppc-instructions (eieio): Missing instruction
758 Tue Oct 24 20:55:29 1995 Andrew Cagney <cagney@highland.com.au>
760 * build-psim: New shell script - see internals for usage,
761 simplifies the process of building custom simulators.
763 Mon Oct 23 23:48:59 1995 Andrew Cagney <cagney@highland.com.au>
765 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
766 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
767 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
768 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
769 the instruction or data critical paths.
771 * FIXME: need to set up OS_EMUL_INLINE/EMUL_GENERIC_INLINE but
772 not on critical path.
774 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
775 the inclusion of device_tree.c/emul_generic.c.
777 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
779 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace
780 system.[hc]. Start of suport for multiple emulations and
781 emulation state (os_emul object).
783 * emul_generic.[hc]: Start of code to implement proper system call
786 Sun Oct 22 21:33:51 1995 Andrew Cagney <cagney@highland.com.au>
788 * cpu.h, cpu.c (cpu_init): New function, zero the registers before
789 the processor is started. Fixes problem of registers being
790 undefined when restarting from within gdb.
792 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
793 instruction cache (if present). Fixes problem of cpu caching gdb
794 breakpoint instructions.
796 FIXME: PSIM sometimes aborts calling error(), it should instead
797 call sim_error() say which takes care of housekeeping such as
798 saving the CIA before calling error.
800 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
801 used when restarting a simulation because the latter has the
802 unwanted side effect (well I as a kernel hacker think it is) of
803 performing an isync when the instruction stream doesn't contain
806 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
808 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
809 monitoring module. Counts both instructions issued and
812 * NOTE: mon does not contain to count instruction loads as this
813 information is already available from the mon_issue() hook.
815 * FIXME: mon doesn't have access to register usage information.
816 This is needed if the user wants to monitor things like register
819 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
821 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
822 a common monitor to each of the cpus. Delete
823 cpu_increment_number_of_insns() and cpu_get_number_of_insns()
824 replaced by copied code in mon.[hc].
826 Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au>
828 * sim_calls.c, main.c, psim.c (psim_create): always create
829 `WITH_SMP' cpus. The actual number of CPU's active in a
830 simulation run is taken from the device node: /init/smp (an
831 integer). WITH_SMP changed to 2 (remember to put it back to 0).
833 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
835 * system.c: More system call emulation. If code appears NetBSD
836 specific, make conditional to being compiled on a NetBSD system
839 Wed Oct 18 23:02:20 1995 Andrew Cagney <cagney@highland.com.au>
841 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
842 lf.[ch](new), table.[ch](new): Split into two generators - igen
843 that outputs the instruction tables and dgen that outputs the spr
844 tables. Add -f (filter out) flag to igen to filter out certain
845 instructions (ex 64 bit ones) from the created tables. Include
846 $(LIBIBERTY_LIB) in link options in case host lacks some libc
849 * NOTE: igen, since it was originally written for the
850 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
852 * Makefile.in, std-config.h, ppc-cache-rules(new),
853 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
854 cache-rule and opcode-rule tables from macros found std-config.h.
855 Delete corresponding macro's from std-config.h.
857 * FIXME: under this new igen scheme, when playing around with igen
858 options, you'll find that depenencies don't work very well.
860 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
861 an table of all the instructions. Code to output a type
862 enumerating all the instructin names.
864 * igen.c(lf_print_c_semantic): Move call to increment instruction
865 counter so that it occures _after_ the instruction has been fully
866 validated, was double counting illegal/invalid instructions. Add
867 conditional so only compiled in when WITH_PROFILE enabled (enabled
870 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
871 itable.h, count individual instruction types not just total,
872 adjust reporting functions to output this.
874 * ppc-instructions (64 bit Load Doubleword with Update Indexed):
875 Had 32./ instead of 31./
877 * ppc-instructions (64 bit Store Double Word Conditional Indexed):
878 bitrot - updated to use newer CR register operators.
880 * ppc-instructions (64bit Floating Convert from Integer
881 Doubleword): Correct call to Round_Float().
883 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
885 * basics.h: #include "sim_callbacks.h" earlier so that its
886 prototypes are declared in all other header files.
888 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
889 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into
892 * FIXME: the bits.h/bits.c macro's should be replaced with
893 (inline) c functions.
895 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
896 Add size of buffer argument to functions writing a string into a
897 buffer. Check for buffer overflow.
899 Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au>
901 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing
902 of each device. Make parameter names consistent so macros work.
903 Use macro's in device functions.
905 * device_tree.c, devices.h, devices.c: include path to device in a
906 devices node when creating it.
908 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.
910 * core.c: add tracing of core-device, adjust parameter names in
911 core functions to be consistent with those in devices*.
913 Sun Oct 15 20:33:20 1995 Andrew Cagney <cagney@highland.com.au>
915 * debug.h, debug.c (trace_option): New function. Parses the trace
916 option, updating the trace array.
918 * debug.h, debug.c (trace_usage): New function. Outputs the list
919 of all possible trace options.
921 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
922 parse trace options specified with the simpler -t flag. Adjust
925 * FIXME: basic parsing of command line options is still duplicated
926 by main.c and sim_calls.c
928 Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com>
930 * Makefile.in (clean): Delete *.i and *.out files.
932 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
933 macros for either assignment or return. Fix SWAP_8 to use a
934 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
935 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
936 that hardwired swapping on/off, let optimizer delete dead code.
938 * main.c (main): Add printf that we caught a signal and print out
941 Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com>
943 * Makefile.in: Remove tabs from otherwise empty line.
944 Confuses many non-GNU versions of "make".
946 Wed Oct 18 08:51:25 1995 Michael Meissner <meissner@tiktok.cygnus.com>
948 * Makefile.in (clean): Delete files produced by gen.
950 Mon Oct 16 17:34:24 1995 Michael Meissner <meissner@tiktok.cygnus.com>
952 * gen.c (lf_print_c_semantic_function): Move counting # of
953 instructions here so it works with caching.
954 (gen_idecode_c): Move from here.
956 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
958 * gen.c, ppc-instructions, psim.c: Fix code for generating
959 cracking instruction cache. Delete the code that cached just the
960 result from doing an instruction lookup - this ran slower than no
963 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
965 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
967 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
968 TCL when gdb is linked with the simulator.
969 * debug.c (ppc_trace): Ditto.
970 * sim_calls.c (sim_open): Change trace -> ppc_trace.
971 * main.c (main): Ditto.
973 * cpu.c (cpu_add_commas): Remove extra static.
975 Thu Oct 12 11:35:53 1995 Michael Meissner <meissner@tiktok.cygnus.com>
977 * Makefile.in (psim.o): Now that inlines are turned on, make
978 psim.o depend on all sources.
980 * cpu.c (cpu_add_commas): New function to format a long with
982 (cpu_print_info): Use it to print number_of_insns.
984 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
986 (ENDIAN_N): If both target and host byte orders are known, don't
987 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
989 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
990 to allow target specific H2T_n/T2H_n macros to be used.
991 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
992 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
993 of the 3 instruction sequence that runs on 386s.
995 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
996 specified on the compile line.
997 (WITH_BSWAP): If not defined, define as 0.
999 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
1000 default inline support. Pass INLINE_CFLAGS when compiling.
1002 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
1003 INLINE_DEVICES since GCC doesn't like inline functions that
1004 accept variable arguments.
1005 (stack_ioctl_callback): Make function just static because GCC
1006 doesn't like inline functions that accept variable arguments.
1008 * devices.h (STATIC_DEVICES): Define as empty if not defined.
1010 * inline.c: Correct pathnames of included C files to match current
1013 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
1014 non-zero, define STATIC_DEVICES to be static.
1016 * std-config.h (INLINE): If GNU C and optimizing, define this as
1018 (DEFAULT_INLINE): If not defined, define as 0.
1019 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
1020 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
1021 ({SPREG,IDECODE}_INLINE): Ditto.
1023 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1025 * ppc-instructions: Initial cut of floating point suport added.
1026 Of note include - use of host IEEE floating point instructions,
1027 use of PowerPC manual pseudo code to handle the FPSCR. It is not
1028 currently a pretty sight.
1030 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
1031 merge into core.h, core.c, core_n.h. The type memory_map replaced
1032 with core_map. This removes a level of pointer indirection when
1033 translating an address.
1035 * memory_map.h, memory_map.c, memory_map_n.h: delete.
1037 * Makefile.in et.al (sorry): tweek to use new core, core_map and
1040 Wed Oct 11 12:10:26 1995 Andrew Cagney <cagney@highland.com.au>
1042 * sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to
1043 most of the other functions in sim_calls.c.
1045 * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
1046 Add macros to better cover up `generic' code. Makes it possible
1047 to step through the generic code!
1049 * vm.c, vm_n.h, Makefile.in: ditto
1051 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
1053 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
1054 callback interface so that there is a read/write buffer but no
1055 read/write_word. VEA default memory read/write handler sometimes
1056 couldn't resolve an access and of those some were for a memory
1057 fault and some were because gdb was making a bogus request.
1059 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
1060 eliminate transfer_mode (raw or cooked) parameter from read/write
1063 Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au>
1065 * ppc-instructions (fmul, fmuls): correct instruction format - had
1068 Wed Oct 4 17:31:12 1995 Andrew Cagney <cagney@highland.com.au>
1070 * psim.c, device_tree.h, device_tree.c, devices.c (printd_*,
1071 scand_*): new functions to parse/print fields in device names
1072 while hiding any machine dependency.
1074 * devices.c, psim.c: Change the stack init code so that it is
1075 handled by a device. Arguments passed across using a device ioctl
1078 * devices.h, devices.c: device ioctl callback changed to allow a
1079 variable number of arguments. This gives greater flexability and
1080 greater chance of bugs.
1082 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
1084 * main.c (printf_filtered, error): Missing va_end() to close off
1085 variable argument use.
1087 * Makefile.in (tmp-gencode): comment out hack to get around some
1088 versions of make not handling files being created as side-effects.
1090 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
1091 alternative file name to use in output files for things like #line
1094 Makefile.in (tmp-gencode): Use gen -n so that debug info is
1097 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the
1100 Sat Oct 7 22:40:59 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1102 * sim_calls.c (sim_set_callbacks): Define new function.
1104 Fri Oct 6 17:23:10 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1106 * psim.c (psim_print_info): Print exit status or signal number.
1108 Mon Oct 2 11:46:37 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1110 * cpu.c (struct _cpu): Add number_of_insns field to trace how many
1111 instructions are executed.
1112 (cpu_increment_number_of_insns): New function to increment the
1113 number of instructions issued.
1114 (cpu_get_number_of_insns): New function to return the number of
1115 instructions issued.

1293 * psim/ppc: Re-arange entire directory structure so that
1294 everything lives in the one directory. While a pain for cleaning,
1295 makes building across multiple architectures much simpler.
1297 * devices.c, device_tree.c: Added code that provides a simple
1298 illustration of how an interrupt control device could be
1301 * devices.c: Added code so that the dumb console device can read
1302 (from stdin) as well as write to stdout.
