471 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
472 make them functions again. Appears 2.6.3 is confused by just a
475 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
477 * ppc-endian.c (SWAP_8): Fix 8 byte swap!

480 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
481 matched the compiled in ones.
483 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
484 trace_semantics is now different to trace_idecode, the former

502 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
503 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
504 the instruction or data critical paths.
506 * FIXME: need to set up OS_EMUL_INLINE/EMUL_GENERIC_INLINE but
507 not on critical path.
509 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
510 the inclusion of device_tree.c/emul_generic.c.
512 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>

525 undefined when restarting from within gdb.
527 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
528 instruction cache (if present). Fixes problem of cpu caching gdb
529 breakpoint instructions.
531 FIXME: PSIM sometimes aborts calling error(), it should instead
532 call sim_error() say which takes care of housekeeping such as
533 saving the CIA before calling error.
535 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
536 used when restarting a simulation because the latter has the
537 unwanted side effect (well I as a kernel hacker think it is) of
538 performing an isync when the instruction stream doesn't contain
541 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
543 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
544 monitoring module. Counts both instructions issued and
547 * NOTE: mon does not contain to count instruction loads as this
548 information is already available from the mon_issue() hook.
550 * FIXME: mon doesn't have access to register usage information.
551 This is needed if the user wants to monitor things like register
554 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
556 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach

563 * sim_calls.c, main.c, psim.c (psim_create): always create
564 `WITH_SMP' cpus. The actual number of CPU's active in a
565 simulation run is taken from the device node: /init/smp (an
566 integer). WITH_SMP changed to 2 (remember to put it back to 0).
568 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
570 * system.c: More system call emulation. If code appears NetBSD

578 that outputs the instruction tables and dgen that outputs the spr
579 tables. Add -f (filter out) flag to igen to filter out certain
580 instructions (ex 64 bit ones) from the created tables. Include
581 $(LIBIBERTY_LIB) in link options in case host lacks some libc
584 * NOTE: igen, since it was originally written for the
585 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
587 * Makefile.in, std-config.h, ppc-cache-rules(new),
588 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
589 cache-rule and opcode-rule tables from macros found std-config.h.
590 Delete corresponding macro's from std-config.h.
592 * FIXME: under this new igen scheme, when playing around with igen
593 options, you'll find that depenencies don't work very well.
595 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
596 an table of all the instructions. Code to output a type
597 enumerating all the instructin names.
599 * igen.c(lf_print_c_semantic): Move call to increment instruction
600 counter so that it occures _after_ the instruction has been fully
601 validated, was double counting illegal/invalid instructions. Add
602 conditional so only compiled in when WITH_PROFILE enabled (enabled
605 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
606 itable.h, count individual instruction types not just total,
607 adjust reporting functions to output this.
609 * ppc-instructions (64 bit Load Doubleword with Update Indexed):
610 Had 32./ instead of 31./
612 * ppc-instructions (64 bit Store Double Word Conditional Indexed):
613 bitrot - updated to use newer CR register operators.
615 * ppc-instructions (64bit Floating Convert from Integer
616 Doubleword): Correct call to Round_Float().
618 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>

621 prototypes are declared in all other header files.
623 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
624 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into

628 (inline) c functions.
630 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
631 Add size of buffer argument to functions writing a string into a
632 buffer. Check for buffer overflow.

641 devices node when creating it.
643 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.
645 * core.c: add tracing of core-device, adjust parameter names in
646 core functions to be consistent with those in devices*.
648 Sun Oct 15 20:33:20 1995 Andrew Cagney <cagney@highland.com.au>
650 * debug.h, debug.c (trace_option): New function. Parses the trace
651 option, updating the trace array.

656 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
657 parse trace options specified with the simpler -t flag. Adjust
660 * FIXME: basic parsing of command line options is still duplicated
661 by main.c and sim_calls.c
663 Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com>
665 * Makefile.in (clean): Delete *.i and *.out files.
667 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
668 macros for either assignment or return. Fix SWAP_8 to use a
669 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
670 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
671 that hardwired swapping on/off, let optimizer delete dead code.

693 * gen.c, ppc-instructions, psim.c: Fix code for generating
694 cracking instruction cache. Delete the code that cached just the
695 result from doing an instruction lookup - this ran slower than no
698 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
700 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).

717 (cpu_print_info): Use it to print number_of_insns.
719 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
721 (ENDIAN_N): If both target and host byte orders are known, don't
722 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
724 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
725 to allow target specific H2T_n/T2H_n macros to be used.
726 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
727 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
728 of the 3 instruction sequence that runs on 386s.
730 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
731 specified on the compile line.
732 (WITH_BSWAP): If not defined, define as 0.

735 default inline support. Pass INLINE_CFLAGS when compiling.
737 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
738 INLINE_DEVICES since GCC doesn't like inline functions that
739 accept variable arguments.
740 (stack_ioctl_callback): Make function just static because GCC
741 doesn't like inline functions that accept variable arguments.
743 * devices.h (STATIC_DEVICES): Define as empty if not defined.
745 * inline.c: Correct pathnames of included C files to match current
748 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be

760 * ppc-instructions: Initial cut of floating point suport added.
761 Of note include - use of host IEEE floating point instructions,
762 use of PowerPC manual pseudo code to handle the FPSCR. It is not
763 currently a pretty sight.
765 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
766 merge into core.h, core.c, core_n.h. The type memory_map replaced
767 with core_map. This removes a level of pointer indirection when
768 translating an address.
770 * memory_map.h, memory_map.c, memory_map_n.h: delete.
772 * Makefile.in et.al (sorry): tweek to use new core, core_map and

786 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
788 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
789 callback interface so that there is a read/write buffer but no
790 read/write_word. VEA default memory read/write handler sometimes
791 couldn't resolve an access and of those some were for a memory
792 fault and some were because gdb was making a bogus request.
794 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
795 eliminate transfer_mode (raw or cooked) parameter from read/write

810 handled by a device. Arguments passed across using a device ioctl
813 * devices.h, devices.c: device ioctl callback changed to allow a
814 variable number of arguments. This gives greater flexability and
815 greater chance of bugs.
817 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
819 * main.c (printf_filtered, error): Missing va_end() to close off
820 variable argument use.

823 versions of make not handling files being created as side-effects.
825 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
826 alternative file name to use in output files for things like #line
829 Makefile.in (tmp-gencode): Use gen -n so that debug info is
832 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the

857 * psim.c (psim_print_info): New function to iterate over each of
858 the CPU's calling cpu_print_info.
860 * psim.h,cpu.h: Add new declarations.
862 * sim_calls.c (sim_open): Add argument processing to add the same
863 switches main.c accepts for the standalone processor.
864 (sim_close): Call psim_print_info if -I.
