20 * {ppc-instructions,igen.c}: More global changes to add model
23 Tue Nov 14 04:47:25 1995 Michael Meissner <meissner@tiktok.cygnus.com>
25 * Makefile.in (devices.o, main.o): Update dependency.
27 * igen.c (gen_model_h): Use correct variable in loop.

40 (gen_itable_h,itable_c_insn): Ditto.
41 (model support): Move model support around, add support for
42 model-data, model-internal. Use annex field for model-macros
45 * configure.in (--enable-sim-inline): If --enable-sim-inline=no,
46 also define INLINE as nothing.
47 * configure: Regenerate.
49 * std-config.h (INLINE): Rather than nuking INLINE, only define it
50 as __inline__ if any of the INLINE flags are non-zero.

62 m[tf]tb with m[tf]spr.
64 * ppc-instructions (mtspr, mfspr): Fix mttbl - wasn't storing
67 Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au>
69 * std-config.h (INLINE, STATIC_INLINE): Was being set to static
70 inline.. Only problem being that with ppc-opcode-simple this gave
71 it the chance to inline all the idecode functions with potentially
72 disasterous results on a 16mb PC. For moment hobble INLINE.
74 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
77 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
78 Firstly make them errors and secondly remove the options gcc-245
81 Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
83 * misc.c (zalloc), cpu.c (cpu_init), devices
84 (console_io_read_buffer_callback, icu_io_read_buffer_callback,
85 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
86 sim_calls.c (zalloc) : replace bzero() with memset().
88 * emul_netbsd.c (write_direntries), psim.c (psim_read_register,
89 psim_write_register): replace bcopy() with memcpy().
91 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
93 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
94 force DEFAULT_INLINE to 0 rather then trusting the std
97 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
99 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
100 generation of switch entries in tables - treat the same as
101 cracking/semantic functions.
103 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
104 of a boolean switch statement (field zero or non-zero).
106 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
107 switch/table generation ability of igen.
109 * igen.c (idecode_switch_leaf): Fix code output when a switch
110 statement needs to look up a table.
112 * igen.c (idecode_declare_if_switch): New function called from
113 gen_idecode_c - need to declare any idecode switch functions
114 before they are used in idecode tables.
116 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
117 idecode_crack_insn): Add is_inline_function argument to code
118 printing cracker functions which indicates if STATIC_IDECODE or
119 STATIC_INLINE_IDECODE should be used for definition. For
120 idecode_crack_insn (which implies not duplicating/expanding) don't
121 declare function as inline - we assume that the only time this is
122 code is generated is when things are being tested. For
123 idecode_crack_leaf, make static (instead of INLINE) if the
124 instructions parent is a table as function will always be called
127 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
128 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
129 called directly, all others are called via a table.
131 * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
132 semantics_h_insn, semantics_h_function,
133 lf_print_c_semantic_function, semantics_c_function): Add
134 is_inline_function argument to lf_print_semantic_function_header
135 to indicate if an inline or static function declaration/definition
136 should be output. Depending on situtation call accordingly:
137 functions (not instruction semantic routines) are always inline;
138 Semantic routines are made inline when there is no icache (cache
139 will contain the function address) and are duplicating (see above)
140 and the parent of the instruction is a switch statement.
142 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
143 and moved to insn_table_find_opcode_field.
145 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
147 * igen.c (model_c_insn): Suggestion - document the name of the
148 instruction on each line of the instruction model table.
150 Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au>
152 * emul_netbsd.c (do_ioctl): Cleanup compilation.
154 * sim_callbacks.h (__attribute__): Only define if not defined (was
155 already defined on NetBSD host).
157 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>

160 macro, indicates if the PowerPC's horrible XOR endian mode should
161 be suported. Add to configure and make.
163 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
164 (vm_instruction_map_read): If XOR endian, xor the address
165 with a value from an xor table (indexed by size of access).
167 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
168 set up xor table to xor if there is a conflict between the
169 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
170 check of suported change of endian mode from cpu.c to vm.c.
172 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
173 Hopefully added correct hack to handle XOR endian mode.
175 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
176 little endian mode, the model accepts miss aligned transfers.
178 FIXME: Need to create an `init' device that, during
179 initializatioin for XOR mode, it mushes (XOR address) all the dma
180 data before passing it on to the core for storage. Just like the
183 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
185 * devices.c (halt_io_write_buffer_callback): Use value written to
186 halt device to determine exit status. Thus allowing
187 success/failure of OEA tests.
189 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au>
191 * ppc-instructions (icbi): If icache present flush it.

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

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

600 Fri Nov 3 11:37:24 1995 Michael Meissner <meissner@tiktok.cygnus.com>
602 * ppc-instructions (data cache instructions): Make all data cache
603 instructions nops instead of invalid instructions.
605 * Makefile.in (CONFIG_CFLAGS): Add ALIGNMENT_CFLAGS and
606 TIMEBASE_CFLAGS which weren't included.
608 Thu Nov 2 08:54:04 1995 Michael Meissner <meissner@tiktok.cygnus.com>
610 * Makefile.in: Uncomment built file dependencies.
612 * configure.in: Rewrite --enable-sim switch handling to use the
613 autoconf builtins so it works correctly if the configure or
614 Makefile.in files are modified and make decides to rebuild
615 Makefile. Also document all of the --enable-sim switches
616 supported. Check whether getrusage and sys/resource.h are
618 * config.in: Regenerate.
619 * configure: Regenerate.
620 * Makefile.in: Add support for all of the variables set with
621 --enable-sim switches.
623 * Makefile.in (clean): make clean now removes all built sources as
626 * cpu.c: Use HAVE_STRING_H, HAVE_STRINGS_H, HAVE_UNISTD_H,
627 HAVE_TIME_H, HAVE_SYS_TIMES_H, HAVE_SYS_RESOURCE_H defined in
628 the generated config.h.
630 * device_tree.c: Ditto.
633 * emul_netbsd.c: Ditto.
638 * registers.c: Ditto.
643 * main.c (main): Call psim_print_info with verbose == 2.
645 * mon.c (mon_print_info): Align the cpu number and number of
646 instructions fields. Do not print an instruction category if the
647 CPU did not execute any of those instructions. Print out number
648 of reads and writes. If getrusage is supported, print out number
649 of simulated instructins per second.
651 * configure.in: Add support for --enable-sim-opcode=stupid.
652 * configure: Regenerate.
654 Wed Nov 1 23:46:59 1995 Andrew Cagney <cagney@highland.com.au>
656 * std-config (INLINE_DEVICE_TREE): Don't inline either of
657 device_tree.c or devices.c. There is no significant gain.
659 * configure.in, Makefile.in: add --enable-sim-icache=[0-9]* and
662 Wed Nov 1 23:46:59 1995 Andrew Cagney <cagney@highland.com.au>
664 * igen.c (main), misc.h (target_a2i, i2target), misc.c: Add
665 functions to convert between target and igen internal bit numbers.
666 Make IO go through these functions. Add -b (bit size) and -h (high
667 bit nr) options to igen. Typical usage would be: ./igen -b 16 -h
668 15 for a 16 bit instruction format with the msb given a number 15.
670 Wed Nov 1 22:17:32 1995 Andrew Cagney <cagney@highland.com.au>
672 * dgen.c (main): Was outputting optarg even when it was NULL.
674 Tue Oct 31 23:48:33 1995 Andrew Cagney <cagney@highland.com.au>
676 * vm_n.h (vm_data_map_load_N, vm_data_map_store_n), debug.h,
677 debug.c: Add tracing of load/store unit (virtual) with -t
680 Tue Oct 31 21:44:01 1995 Andrew Cagney <cagney@highland.com.au>
682 * std-config.h (WITH_ENVIRONMENT): Add USER_ENVIRONMENT which does
683 not include things such as the time base and events.
685 * interrupt.c, sim_calls.c, cpu.h, vm.c, configure.in: Add UEA to
686 all environment switches for above.
688 * psim.c (psim_create): ditto - new device tree node name is
689 /options/environment-architecture with values user, virtual and
692 Tue Oct 31 21:31:32 1995 Andrew Cagney <cagney@highland.com.au>
694 * ppc-opcode-stupid: Third example of use of opcode table - this
695 one expands all mtspr/mfspr and branch instructions. Appears to
696 give about a 10% gain in performance if everything enabled. Also
697 takes about 150mb of swap to build.
699 Wed Nov 1 10:49:48 1995 Michael Meissner <meissner@tiktok.cygnus.com>
701 * emul_netbsd.c (do_exit): Print arguments and close parenthesis
702 if tracing, since exit doesn't go through emul_exit_call.
703 (do_read): Print arguments if tracing.
709 (do_sigprocmask): Replace trace with printing arguments if
711 (do_ioctl): Print arguments if tracing.

732 * Makefile.in: Add filter_filename support.
734 * ppc-instructions (dcbi, icbi): Make these NOPs rather than
735 invalid instructions.
737 * configure.in: Add support for more --enable-sim-* switches.
738 Use config.make and config.hdr to write to Makefile and config.h
739 respectively. Don't rewrite Makefile, just append to it.
740 * configure: Regenerate.
741 * config.{make,hdr}: New shell scripts.
743 * Makefile.in: Remove all variables set by configure.in.
744 (psim.o): Depend on $(BUILT_SRC) also.
746 * emul_netbsd.c (do_gettimeofday,do_getrusage): When comparing an
747 integer, use 0, not NULL.

751 * configure.in: Add support for --enable-sim-inline,
752 --enable-sim-bswap, --enable-sim-cflags, --enable-sim-complex,
753 --enable-sim-switch, --enable-sim-duplicate, --enable-sim-filter,
754 and --enable-sim-endian switch to control various Makefile
756 * configure: Regenerate from configure.in.
757 * Makefile.in: Add various Make variables that the various
760 * std-config.h (DEFAULT_INLINE): Don't set this to 2 if using GCC
761 and optimizing by default.
763 Fri Oct 27 19:26:27 1995 Andrew Cagney <cagney@highland.com.au>
765 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
766 make them functions again. Appears 2.6.3 is confused by just a
769 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
771 * ppc-endian.c (SWAP_8): Fix 8 byte swap!
773 * psim.c (psim_create): Not correctly checking that runtime
774 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
775 matched the compiled in ones.
777 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
778 trace_semantics is now different to trace_idecode, the former
781 Tue Oct 24 21:54:13 1995 Andrew Cagney <cagney@highland.com.au>
783 * ppc-instructions (mtsrin): Missing instruction
784 * ppc-instructions (mfsrin): Missing instruction
785 * ppc-instructions (eieio): Missing instruction
787 Tue Oct 24 20:55:29 1995 Andrew Cagney <cagney@highland.com.au>
789 * build-psim: New shell script - see internals for usage,
790 simplifies the process of building custom simulators.
792 Mon Oct 23 23:48:59 1995 Andrew Cagney <cagney@highland.com.au>
794 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
795 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
796 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
797 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
798 the instruction or data critical paths.
800 * FIXME: need to set up OS_EMUL_INLINE/EMUL_GENERIC_INLINE but
801 not on critical path.
803 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
804 the inclusion of device_tree.c/emul_generic.c.
806 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
808 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace
809 system.[hc]. Start of suport for multiple emulations and
810 emulation state (os_emul object).
812 * emul_generic.[hc]: Start of code to implement proper system call
815 Sun Oct 22 21:33:51 1995 Andrew Cagney <cagney@highland.com.au>
817 * cpu.h, cpu.c (cpu_init): New function, zero the registers before
818 the processor is started. Fixes problem of registers being
819 undefined when restarting from within gdb.
821 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
822 instruction cache (if present). Fixes problem of cpu caching gdb
823 breakpoint instructions.
825 FIXME: PSIM sometimes aborts calling error(), it should instead
826 call sim_error() say which takes care of housekeeping such as
827 saving the CIA before calling error.
829 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
830 used when restarting a simulation because the latter has the
831 unwanted side effect (well I as a kernel hacker think it is) of
832 performing an isync when the instruction stream doesn't contain
835 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
837 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
838 monitoring module. Counts both instructions issued and
841 * NOTE: mon does not contain to count instruction loads as this
842 information is already available from the mon_issue() hook.
844 * FIXME: mon doesn't have access to register usage information.
845 This is needed if the user wants to monitor things like register
848 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
850 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
851 a common monitor to each of the cpus. Delete
852 cpu_increment_number_of_insns() and cpu_get_number_of_insns()
853 replaced by copied code in mon.[hc].
855 Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au>
857 * sim_calls.c, main.c, psim.c (psim_create): always create
858 `WITH_SMP' cpus. The actual number of CPU's active in a
859 simulation run is taken from the device node: /init/smp (an
860 integer). WITH_SMP changed to 2 (remember to put it back to 0).
862 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
864 * system.c: More system call emulation. If code appears NetBSD
865 specific, make conditional to being compiled on a NetBSD system
868 Wed Oct 18 23:02:20 1995 Andrew Cagney <cagney@highland.com.au>
870 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
871 lf.[ch](new), table.[ch](new): Split into two generators - igen
872 that outputs the instruction tables and dgen that outputs the spr
873 tables. Add -f (filter out) flag to igen to filter out certain
874 instructions (ex 64 bit ones) from the created tables. Include
875 $(LIBIBERTY_LIB) in link options in case host lacks some libc
878 * NOTE: igen, since it was originally written for the
879 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
881 * Makefile.in, std-config.h, ppc-cache-rules(new),
882 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
883 cache-rule and opcode-rule tables from macros found std-config.h.
884 Delete corresponding macro's from std-config.h.
886 * FIXME: under this new igen scheme, when playing around with igen
887 options, you'll find that depenencies don't work very well.
889 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
890 an table of all the instructions. Code to output a type
891 enumerating all the instructin names.
893 * igen.c(lf_print_c_semantic): Move call to increment instruction
894 counter so that it occures _after_ the instruction has been fully
895 validated, was double counting illegal/invalid instructions. Add
896 conditional so only compiled in when WITH_PROFILE enabled (enabled
899 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
900 itable.h, count individual instruction types not just total,
901 adjust reporting functions to output this.
903 * ppc-instructions (64 bit Load Doubleword with Update Indexed):
904 Had 32./ instead of 31./
906 * ppc-instructions (64 bit Store Double Word Conditional Indexed):
907 bitrot - updated to use newer CR register operators.
909 * ppc-instructions (64bit Floating Convert from Integer
910 Doubleword): Correct call to Round_Float().
912 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
914 * basics.h: #include "sim_callbacks.h" earlier so that its
915 prototypes are declared in all other header files.
917 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
918 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into
921 * FIXME: the bits.h/bits.c macro's should be replaced with
922 (inline) c functions.
924 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
925 Add size of buffer argument to functions writing a string into a
926 buffer. Check for buffer overflow.
928 Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au>
930 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing
931 of each device. Make parameter names consistent so macros work.
932 Use macro's in device functions.
934 * device_tree.c, devices.h, devices.c: include path to device in a
935 devices node when creating it.
937 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.
939 * core.c: add tracing of core-device, adjust parameter names in
940 core functions to be consistent with those in devices*.
942 Sun Oct 15 20:33:20 1995 Andrew Cagney <cagney@highland.com.au>
944 * debug.h, debug.c (trace_option): New function. Parses the trace
945 option, updating the trace array.
947 * debug.h, debug.c (trace_usage): New function. Outputs the list
948 of all possible trace options.
950 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
951 parse trace options specified with the simpler -t flag. Adjust
954 * FIXME: basic parsing of command line options is still duplicated
955 by main.c and sim_calls.c
957 Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com>
959 * Makefile.in (clean): Delete *.i and *.out files.
961 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
962 macros for either assignment or return. Fix SWAP_8 to use a
963 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
964 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
965 that hardwired swapping on/off, let optimizer delete dead code.
967 * main.c (main): Add printf that we caught a signal and print out
970 Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com>
972 * Makefile.in: Remove tabs from otherwise empty line.
973 Confuses many non-GNU versions of "make".
975 Wed Oct 18 08:51:25 1995 Michael Meissner <meissner@tiktok.cygnus.com>
977 * Makefile.in (clean): Delete files produced by gen.
979 Mon Oct 16 17:34:24 1995 Michael Meissner <meissner@tiktok.cygnus.com>
981 * gen.c (lf_print_c_semantic_function): Move counting # of
982 instructions here so it works with caching.
983 (gen_idecode_c): Move from here.
985 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
987 * gen.c, ppc-instructions, psim.c: Fix code for generating
988 cracking instruction cache. Delete the code that cached just the
989 result from doing an instruction lookup - this ran slower than no
992 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
994 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
996 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
997 TCL when gdb is linked with the simulator.
998 * debug.c (ppc_trace): Ditto.
999 * sim_calls.c (sim_open): Change trace -> ppc_trace.
1000 * main.c (main): Ditto.
1002 * cpu.c (cpu_add_commas): Remove extra static.
1004 Thu Oct 12 11:35:53 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1006 * Makefile.in (psim.o): Now that inlines are turned on, make
1007 psim.o depend on all sources.
1009 * cpu.c (cpu_add_commas): New function to format a long with
1011 (cpu_print_info): Use it to print number_of_insns.
1013 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
1015 (ENDIAN_N): If both target and host byte orders are known, don't
1016 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
1018 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
1019 to allow target specific H2T_n/T2H_n macros to be used.
1020 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
1021 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
1022 of the 3 instruction sequence that runs on 386s.
1024 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
1025 specified on the compile line.
1026 (WITH_BSWAP): If not defined, define as 0.
1028 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
1029 default inline support. Pass INLINE_CFLAGS when compiling.
1031 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
1032 INLINE_DEVICES since GCC doesn't like inline functions that
1033 accept variable arguments.
1034 (stack_ioctl_callback): Make function just static because GCC
1035 doesn't like inline functions that accept variable arguments.
1037 * devices.h (STATIC_DEVICES): Define as empty if not defined.
1039 * inline.c: Correct pathnames of included C files to match current
1042 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
1043 non-zero, define STATIC_DEVICES to be static.
1045 * std-config.h (INLINE): If GNU C and optimizing, define this as
1047 (DEFAULT_INLINE): If not defined, define as 0.
1048 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
1049 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
1050 ({SPREG,IDECODE}_INLINE): Ditto.
1052 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1054 * ppc-instructions: Initial cut of floating point suport added.
1055 Of note include - use of host IEEE floating point instructions,
1056 use of PowerPC manual pseudo code to handle the FPSCR. It is not
1057 currently a pretty sight.
1059 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
1060 merge into core.h, core.c, core_n.h. The type memory_map replaced
1061 with core_map. This removes a level of pointer indirection when
1062 translating an address.
1064 * memory_map.h, memory_map.c, memory_map_n.h: delete.
1066 * Makefile.in et.al (sorry): tweek to use new core, core_map and
1069 Wed Oct 11 12:10:26 1995 Andrew Cagney <cagney@highland.com.au>
1071 * sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to
1072 most of the other functions in sim_calls.c.
1074 * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
1075 Add macros to better cover up `generic' code. Makes it possible
1076 to step through the generic code!
1078 * vm.c, vm_n.h, Makefile.in: ditto
1080 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
1082 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
1083 callback interface so that there is a read/write buffer but no
1084 read/write_word. VEA default memory read/write handler sometimes
1085 couldn't resolve an access and of those some were for a memory
1086 fault and some were because gdb was making a bogus request.
1088 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
1089 eliminate transfer_mode (raw or cooked) parameter from read/write
1092 Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au>
1094 * ppc-instructions (fmul, fmuls): correct instruction format - had
1097 Wed Oct 4 17:31:12 1995 Andrew Cagney <cagney@highland.com.au>
1099 * psim.c, device_tree.h, device_tree.c, devices.c (printd_*,
1100 scand_*): new functions to parse/print fields in device names
1101 while hiding any machine dependency.
1103 * devices.c, psim.c: Change the stack init code so that it is
1104 handled by a device. Arguments passed across using a device ioctl
1107 * devices.h, devices.c: device ioctl callback changed to allow a
1108 variable number of arguments. This gives greater flexability and
1109 greater chance of bugs.
1111 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
1113 * main.c (printf_filtered, error): Missing va_end() to close off
