 359                      sregs->trap = TRAP_UNIMP;
 360                      break;
 361                   }
 362         clause that has been pasted around: it's correct in the SCAN and
 363         DIVScc (divide step) cases (where it was probably originally
 364         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 365         ie. instructions only in the SPARC V8 or SPARClite 86x
 366         architectures.  It was also present when not required for SMUL,
 367         SMULcc, UMUL, UMULcc instructions that are present in all
 368         architectures.
 369
 370 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 371
 372         * interf.c (run_sim): Fix a bug in the main loop's handling of
 373         annulled delay slot instructions.  There is precedent for this
 374         change; the _other_ main loop in sis.c gets it right according to
 375         my reading of the code.
 376
 377         The bug is: if an interrupt happens when the next instruction
 378         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 379         with the current values of PC and NPC, so when the trap returns,
 380         the annulled instruction is indeed executed.  Another giveaway is
 381         that the annul flag is cleared in execute_trap(): the information
 382         is demonstrably discarded.
 383
 384         The solution is: perform annulling before looking for traps, in
 385         fact it's neater to do annulling, see if there's an interrupt and
 386         if not, do the instruction, then handle traps be they generated by
 387         interrupts pending or by the instruction we might just have done.
 388         That's what the sis.c one does.
 389
 390 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 391
 392         * sis.h: Add asr17 register for support of SparcLITE (at least the
 393         Hitachi ones I find before me)
 394
 395         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 396         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 397         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 398         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 399         (init_regs): Initialize y and asr17.
 400         NB: In instruction-set space, the Y register is asr0; the
 401         instructions have different names for human reasons only.

 403         * sis.c:
 404         * interf.c: Set boolean mode variable dumbio if invoked with
 405         argument "-dumbio" and mention it of verbose.
 406         * erc32.c: if "dumbio" is set, do not assume that there is a
 407         terminal type device attached to stdin/stdout.  Do not set
 408         buffering or mess with tcsetattr or do any read operations in
 409         order to make UART interrupts; not input data is supported.
 410         This is necessary to allow the sim to be used within the eCos
 411         testing infrastructure where stdin/stdout are pipes to a TCL
 412         program; the sim hangs otherwise.

 762         * erc32.c (port_init):  Disable this for __GO32__ (got no pty's
 763         there either...).
 764
 765 Mon Aug 12 17:04:58 1996  Stu Grossman  (grossman@critters.cygnus.com)
 766
 767         * erc32.c:  Don't include sys/ioctl.h or sys/file.h.  They aren't
 768         necessary.
 769         * (port_init):  Don't even *try* to open pty's under _WIN32.
 770         * Use SIM_ADDR, not caddr_t for declaring vars that hold addresses.
 771         * float.c:  Get rid of #warning.  Makes Microsoft C barf.
 772         * interf.c (sim_open):  Cast fprintf to (fprintf_ftype) to fix
 773         compiler warning.
 774         * (sim_load sim_create_inferior sim_read):  Use prototypes only in
 775         decls, not defs.
 776         * Get rid of enum sim_stop.  It's defined in remote-sim.h.
 777         * (sim_stop_reason):  Define SIGTRAP if _WIN32.
 778         * sis.h:  Include ansidecl.h and remote-sim.h.

 781
 782         * erc32.c (mec_reset mec_read mec_write memory_read memory_write),
 783         sis.h:  Get rid of all uses of long long's.
 784         * (close_port read_uart write_uart uarta_tx):  Don't seg fault
 785         when can't open pty's.
 786         * exec.c:  Add two new instructions: smul, and divscc.
 787         * interf.c (flush_windows):  New routine to flush the register
 788         windows out to the stack just before returning to GDB.  Makes
 789         backtraces work much better.

 791 Wed Jun 26 12:19:11 1996  Jason Molenda  (crash@godzilla.cygnus.co.jp)
 792
 793         * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir,
 794         INSTALL_PROGRAM, INSTALL_DATA): Use autoconf-set values.
 795         (docdir, oldincludedir): Removed.
 796         * configure.in (AC_PREREQ): autoconf 2.5 or higher.
 797         (AC_PROG_INSTALL): Added.
 798         * configure: Rebuilt.
 799
 800 Mon Jun 24 14:19:07 1996  Ian Lance Taylor  <ian@cygnus.com>
 801
 802         * configure.in: Call AC_PROG_CC before running configure.host.
 803         * configure: Rebuild with autoconf 2.10.
 804
 805 Tue Jun  4 10:37:12 1996  Tom Tromey  <tromey@csk3.cygnus.com>
 806
 807         * Makefile.in (install): Don't check to see if tooldir exists.
 808         Make $(tooldir) and $(tooldir)/bin.
 809
 810 Mon Jun  3 12:33:38 1996  Ian Lance Taylor  <ian@cygnus.com>
 811
 812         * Makefile.in (end.h): Use explicit ./ when running end.
 813
 814 Sun May 19 21:05:31 1996  Rob Savoye  <rob@chinadoll.cygnus.com>
 815
 816         * func.c(bfd_load): Don't try to print the filename if the pfbd is
 817         NULL.
 818         * interf.c(sim_load): Pass the whole string, not just the first
 819         byte.
 820
 821 Version 2.1 26-02-96
 822 --------------------
 823
 824 * Fixed bug in "go" command.
 825
 826 version 2.0 05-02-96
 827 --------------------
 828
 829 * Fixed bug in interrupt force register (erc32.c).
 830
 831 * Change file load function to use bfd_openr.
 832
 833 * SIS should now be endian independent.
 834
 835 version 1.8 24-11-95
 836 --------------------
 837
 838 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 839   the resource dependencies right.
 840
 841 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 842   but no FPU trap is generated.
 843
 844 version 1.7.1 31-10-95
 845 --------------------
 846
 847 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 848   the FPU stays in execute mode.
 849
 850 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 851
 852
 853 version 1.7 25-10-95
 854 --------------------
 855
 856 * Interrupt during annuled instruction corrupted return address - fixed.
 857
 858
 859 version 1.6.2 25-10-95
 860 --------------------
 861
 862 * Added -DFAST_UART to Makefile
 863
 864
 865 version 1.6.1 24-10-95
 866 --------------------
 867
 868 * Fixed bug in STDFQ which caused bus error
 869
 870
 871 version 1.6 02-10-95
 872 --------------------
 873
 874 * Modified srt0.s to include code that initiates registers in IU and FPU
 875   and initializes the data segment. The simulator 'load' command does not
 876   longer initialize the data segment!
 877
 878 * Corrected MEC timer operation; scalers now divide the frequency by
 879   (scaler_value + 1).
 880
 881 * MEC breakpoints are not checked during store operation
 882
 883
 884 version 1.5 14-09-95
 885 --------------------
 886
 887 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 888
 889 * Fixed bug that allowed an annuled instruction to cause memory exception.
 890
 891 * The *ws parameter in mem.c should now contain the number of waitstates
 892   required by the memory access (was total number of cycles).
 893
 894 * The supplied srt0.s now clears the BSS (thanks Joel).
 895
 896 version 1.4 22-08-95
 897 --------------------
 898
 899 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 900 some problems on solaris 2.x machines.
 901
 902 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 903 may suffer a bit ...
 904
 905 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 906
 907 version 1.3 26-07-95
 908 --------------------
 909
 910 * Fixed bug in mulscc instruction (how could that ever have worked?)
 911
 912 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 913
 914 version 1.2 13-07-95
 915 --------------------
 916
 917 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 918 one interrupt pending)
 919
 920 * Fixed updating of condition codes during logical instructions (carry and
 921 overflow were not reset)
 922
 923 * Fixed bug in WRTBR (tt field was wrongly over-written)
 924
 925 version 1.1 07-07-95
 926 --------------------
 927
 928 * Fixed several bugs in the interrupt handler and callback routines.
 929 (reported by Paul Warren, Alsys)
