580 Mon Oct 23 23:48:59 1995 Andrew Cagney <cagney@highland.com.au>
582 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
583 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
584 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
585 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
586 the instruction or data critical paths.
588 * FIXME: need to set up OS_EMUL_INLINE/EMUL_GENERIC_INLINE but
589 not on critical path.
591 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
592 the inclusion of device_tree.c/emul_generic.c.
594 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
596 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace
597 system.[hc]. Start of suport for multiple emulations and
598 emulation state (os_emul object).
600 * emul_generic.[hc]: Start of code to implement proper system call
603 Sun Oct 22 21:33:51 1995 Andrew Cagney <cagney@highland.com.au>
605 * cpu.h, cpu.c (cpu_init): New function, zero the registers before
606 the processor is started. Fixes problem of registers being
607 undefined when restarting from within gdb.
609 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
610 instruction cache (if present). Fixes problem of cpu caching gdb
611 breakpoint instructions.
613 FIXME: PSIM sometimes aborts calling error(), it should instead
614 call sim_error() say which takes care of housekeeping such as
615 saving the CIA before calling error.
617 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
618 used when restarting a simulation because the latter has the
619 unwanted side effect (well I as a kernel hacker think it is) of
620 performing an isync when the instruction stream doesn't contain
623 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
625 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
626 monitoring module. Counts both instructions issued and
629 * NOTE: mon does not contain to count instruction loads as this
630 information is already available from the mon_issue() hook.
632 * FIXME: mon doesn't have access to register usage information.
633 This is needed if the user wants to monitor things like register
636 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
638 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
639 a common monitor to each of the cpus. Delete
640 cpu_increment_number_of_insns() and cpu_get_number_of_insns()
641 replaced by copied code in mon.[hc].
643 Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au>
645 * sim_calls.c, main.c, psim.c (psim_create): always create
646 `WITH_SMP' cpus. The actual number of CPU's active in a
647 simulation run is taken from the device node: /init/smp (an
648 integer). WITH_SMP changed to 2 (remember to put it back to 0).
650 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
652 * system.c: More system call emulation. If code appears NetBSD
653 specific, make conditional to being compiled on a NetBSD system
656 Wed Oct 18 23:02:20 1995 Andrew Cagney <cagney@highland.com.au>
658 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
659 lf.[ch](new), table.[ch](new): Split into two generators - igen
660 that outputs the instruction tables and dgen that outputs the spr
661 tables. Add -f (filter out) flag to igen to filter out certain
662 instructions (ex 64 bit ones) from the created tables. Include
663 $(LIBIBERTY_LIB) in link options in case host lacks some libc
666 * NOTE: igen, since it was originally written for the
667 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
669 * Makefile.in, std-config.h, ppc-cache-rules(new),
670 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
671 cache-rule and opcode-rule tables from macros found std-config.h.
672 Delete corresponding macro's from std-config.h.
674 * FIXME: under this new igen scheme, when playing around with igen
675 options, you'll find that depenencies don't work very well.
677 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
678 an table of all the instructions. Code to output a type
679 enumerating all the instructin names.
681 * igen.c(lf_print_c_semantic): Move call to increment instruction
682 counter so that it occures _after_ the instruction has been fully
683 validated, was double counting illegal/invalid instructions. Add
684 conditional so only compiled in when WITH_PROFILE enabled (enabled
687 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
688 itable.h, count individual instruction types not just total,
689 adjust reporting functions to output this.
691 * ppc-instructions (64 bit Load Doubleword with Update Indexed):
692 Had 32./ instead of 31./
694 * ppc-instructions (64 bit Store Double Word Conditional Indexed):
695 bitrot - updated to use newer CR register operators.
697 * ppc-instructions (64bit Floating Convert from Integer
698 Doubleword): Correct call to Round_Float().
700 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
702 * basics.h: #include "sim_callbacks.h" earlier so that its
703 prototypes are declared in all other header files.
705 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
706 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into
709 * FIXME: the bits.h/bits.c macro's should be replaced with
710 (inline) c functions.
712 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
713 Add size of buffer argument to functions writing a string into a
714 buffer. Check for buffer overflow.
716 Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au>
718 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing
719 of each device. Make parameter names consistent so macros work.
720 Use macro's in device functions.
722 * device_tree.c, devices.h, devices.c: include path to device in a
723 devices node when creating it.
725 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.
727 * core.c: add tracing of core-device, adjust parameter names in
728 core functions to be consistent with those in devices*.
730 Sun Oct 15 20:33:20 1995 Andrew Cagney <cagney@highland.com.au>
732 * debug.h, debug.c (trace_option): New function. Parses the trace
733 option, updating the trace array.
735 * debug.h, debug.c (trace_usage): New function. Outputs the list
736 of all possible trace options.
738 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
739 parse trace options specified with the simpler -t flag. Adjust
742 * FIXME: basic parsing of command line options is still duplicated
743 by main.c and sim_calls.c
745 Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com>
747 * Makefile.in (clean): Delete *.i and *.out files.
749 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
750 macros for either assignment or return. Fix SWAP_8 to use a
751 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
752 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
753 that hardwired swapping on/off, let optimizer delete dead code.
755 * main.c (main): Add printf that we caught a signal and print out
758 Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com>
760 * Makefile.in: Remove tabs from otherwise empty line.

770 instructions here so it works with caching.
771 (gen_idecode_c): Move from here.
773 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
775 * gen.c, ppc-instructions, psim.c: Fix code for generating
776 cracking instruction cache. Delete the code that cached just the
777 result from doing an instruction lookup - this ran slower than no
780 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
782 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
784 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
785 TCL when gdb is linked with the simulator.
786 * debug.c (ppc_trace): Ditto.

795 psim.o depend on all sources.
797 * cpu.c (cpu_add_commas): New function to format a long with
799 (cpu_print_info): Use it to print number_of_insns.
801 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
803 (ENDIAN_N): If both target and host byte orders are known, don't
804 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
806 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
807 to allow target specific H2T_n/T2H_n macros to be used.
808 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
809 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
810 of the 3 instruction sequence that runs on 386s.
812 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
813 specified on the compile line.
814 (WITH_BSWAP): If not defined, define as 0.
816 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
817 default inline support. Pass INLINE_CFLAGS when compiling.
819 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
820 INLINE_DEVICES since GCC doesn't like inline functions that
821 accept variable arguments.
822 (stack_ioctl_callback): Make function just static because GCC
823 doesn't like inline functions that accept variable arguments.
825 * devices.h (STATIC_DEVICES): Define as empty if not defined.
827 * inline.c: Correct pathnames of included C files to match current
830 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
831 non-zero, define STATIC_DEVICES to be static.
833 * std-config.h (INLINE): If GNU C and optimizing, define this as
835 (DEFAULT_INLINE): If not defined, define as 0.
836 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.

838 ({SPREG,IDECODE}_INLINE): Ditto.
840 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
842 * ppc-instructions: Initial cut of floating point suport added.
843 Of note include - use of host IEEE floating point instructions,
844 use of PowerPC manual pseudo code to handle the FPSCR. It is not
845 currently a pretty sight.
847 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
848 merge into core.h, core.c, core_n.h. The type memory_map replaced
849 with core_map. This removes a level of pointer indirection when
850 translating an address.
852 * memory_map.h, memory_map.c, memory_map_n.h: delete.
854 * Makefile.in et.al (sorry): tweek to use new core, core_map and

862 * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
863 Add macros to better cover up `generic' code. Makes it possible
864 to step through the generic code!
866 * vm.c, vm_n.h, Makefile.in: ditto
868 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
870 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
871 callback interface so that there is a read/write buffer but no
872 read/write_word. VEA default memory read/write handler sometimes
873 couldn't resolve an access and of those some were for a memory
874 fault and some were because gdb was making a bogus request.
876 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
877 eliminate transfer_mode (raw or cooked) parameter from read/write
880 Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au>
882 * ppc-instructions (fmul, fmuls): correct instruction format - had

888 scand_*): new functions to parse/print fields in device names
889 while hiding any machine dependency.
891 * devices.c, psim.c: Change the stack init code so that it is
892 handled by a device. Arguments passed across using a device ioctl
895 * devices.h, devices.c: device ioctl callback changed to allow a
896 variable number of arguments. This gives greater flexability and
897 greater chance of bugs.
899 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
901 * main.c (printf_filtered, error): Missing va_end() to close off
902 variable argument use.
904 * Makefile.in (tmp-gencode): comment out hack to get around some
905 versions of make not handling files being created as side-effects.
907 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
908 alternative file name to use in output files for things like #line
911 Makefile.in (tmp-gencode): Use gen -n so that debug info is
914 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the

939 * psim.c (psim_print_info): New function to iterate over each of
940 the CPU's calling cpu_print_info.
942 * psim.h,cpu.h: Add new declarations.
944 * sim_calls.c (sim_open): Add argument processing to add the same
945 switches main.c accepts for the standalone processor.
946 (sim_close): Call psim_print_info if -I.
948 * main.c (main): Add comment saying to update sim_calls.c when
949 adding switches. Add -I to call psim_print_info when done.

1112 makes building across multiple architectures much simpler.
1114 * devices.c, device_tree.c: Added code that provides a simple
1115 illustration of how an interrupt control device could be
1118 * devices.c: Added code so that the dumb console device can read
1119 (from stdin) as well as write to stdout.
