 404         Correct the sense of the
 405                   if (!sparclite) {
 406                      sregs->trap = TRAP_UNIMP;
 407                      break;
 408                   }
 409         clause that has been pasted around: it's correct in the SCAN and
 410         DIVScc (divide step) cases (where it was probably originally
 411         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 412         ie. instructions only in the SPARC V8 or SPARClite 86x
 413         architectures.  It was also present when not required for SMUL,
 414         SMULcc, UMUL, UMULcc instructions that are present in all
 415         architectures.

 418
 419         * interf.c (run_sim): Fix a bug in the main loop's handling of
 420         annulled delay slot instructions.  There is precedent for this
 421         change; the _other_ main loop in sis.c gets it right according to
 422         my reading of the code.
 423
 424         The bug is: if an interrupt happens when the next instruction
 425         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 426         with the current values of PC and NPC, so when the trap returns,
 427         the annulled instruction is indeed executed.  Another giveaway is
 428         that the annul flag is cleared in execute_trap(): the information
 429         is demonstrably discarded.
 430
 431         The solution is: perform annulling before looking for traps, in
 432         fact it's neater to do annulling, see if there's an interrupt and
 433         if not, do the instruction, then handle traps be they generated by
 434         interrupts pending or by the instruction we might just have done.
 435         That's what the sis.c one does.
 436
 437 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 438
 439         * sis.h: Add asr17 register for support of SparcLITE (at least the
 440         Hitachi ones I find before me)
 441
 442         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 443         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 444         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 445         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 446         (init_regs): Initialize y and asr17.
 447         NB: In instruction-set space, the Y register is asr0; the
 448         instructions have different names for human reasons only.
 449
 450         * sis.c:
 451         * interf.c: Set boolean mode variable dumbio if invoked with
 452         argument "-dumbio" and mention it of verbose.
 453         * erc32.c: if "dumbio" is set, do not assume that there is a
 454         terminal type device attached to stdin/stdout.  Do not set
 455         buffering or mess with tcsetattr or do any read operations in
 456         order to make UART interrupts; not input data is supported.
 457         This is necessary to allow the sim to be used within the eCos
 458         testing infrastructure where stdin/stdout are pipes to a TCL
 459         program; the sim hangs otherwise.

 482         byte-swapping unnecessary.  Add -sparclite-board option for
 483         emulating RAM found on typical SPARClite boards.  Print
 484         error message for unrecognized option.
 485         * erc32.c: Change RAM address and size from constants to variables,
 486         to allow emulation of SPARClite board RAM.

 492         (get_mem_ptr): Remove unnecessary byte parameter.
 493         (sis_memory_write, sis_memory_read): Store words in target

 498         * sis.c (run_sim): Use revamped memory_read, which makes
 499         byte-swapping unnecessary.
 500         * exec.c (dispatch_instruction): Use revamped memory_read, which
 501         makes byte-swapping and double-word fetching unnecessary.
 502         * func.c (sparclite_board): Declare new variable.
 503         (get_regi): Handle little-endian data.
 504         (bfd_load): Recognize little-endian SPARClite as having

 765
 766         * Makefile.in (run.o): Remove this rule, it hides the one in
 767         ../common/Make-common.in that correctly references the source
 768         in the sibling ../common directory.

 807 Sun Sep  8 14:04:37 1996  Stu Grossman  (grossman@critters.cygnus.com)
 808
 809         * erc32.c (port_init):  Disable this for __GO32__ (got no pty's
 810         there either...).
 811
 812 Mon Aug 12 17:04:58 1996  Stu Grossman  (grossman@critters.cygnus.com)
 813
 814         * erc32.c:  Don't include sys/ioctl.h or sys/file.h.  They aren't
 815         necessary.
 816         * (port_init):  Don't even *try* to open pty's under _WIN32.
 817         * Use SIM_ADDR, not caddr_t for declaring vars that hold addresses.
 818         * float.c:  Get rid of #warning.  Makes Microsoft C barf.
 819         * interf.c (sim_open):  Cast fprintf to (fprintf_ftype) to fix
 820         compiler warning.
 821         * (sim_load sim_create_inferior sim_read):  Use prototypes only in
 822         decls, not defs.

 836         backtraces work much better.
 837
 838 Wed Jun 26 12:19:11 1996  Jason Molenda  (crash@godzilla.cygnus.co.jp)
 839
 840         * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir,

 852 Tue Jun  4 10:37:12 1996  Tom Tromey  <tromey@csk3.cygnus.com>
 853
 854         * Makefile.in (install): Don't check to see if tooldir exists.
 855         Make $(tooldir) and $(tooldir)/bin.
 856

 858
 859         * Makefile.in (end.h): Use explicit ./ when running end.
 860
 861 Sun May 19 21:05:31 1996  Rob Savoye  <rob@chinadoll.cygnus.com>
 862
 863         * func.c(bfd_load): Don't try to print the filename if the pfbd is
 864         NULL.
 865         * interf.c(sim_load): Pass the whole string, not just the first
 866         byte.
 867
 868 Version 2.1 26-02-96
 869 --------------------
 870
 871 * Fixed bug in "go" command.
 872
 873 version 2.0 05-02-96
 874 --------------------
 875
 876 * Fixed bug in interrupt force register (erc32.c).
 877
 878 * Change file load function to use bfd_openr.
 879
 880 * SIS should now be endian independent.
 881
 882 version 1.8 24-11-95
 883 --------------------
 884
 885 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 886   the resource dependencies right.
 887
 888 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 889   but no FPU trap is generated.
 890
 891 version 1.7.1 31-10-95
 892 --------------------
 893
 894 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 895   the FPU stays in execute mode.
 896
 897 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 898
 899
 900 version 1.7 25-10-95
 901 --------------------
 902
 903 * Interrupt during annuled instruction corrupted return address - fixed.
 904
 905
 906 version 1.6.2 25-10-95
 907 --------------------
 908
 909 * Added -DFAST_UART to Makefile
 910
 911
 912 version 1.6.1 24-10-95
 913 --------------------
 914
 915 * Fixed bug in STDFQ which caused bus error
 916
 917
 918 version 1.6 02-10-95
 919 --------------------
 920
 921 * Modified srt0.s to include code that initiates registers in IU and FPU
 922   and initializes the data segment. The simulator 'load' command does not
 923   longer initialize the data segment!
 924
 925 * Corrected MEC timer operation; scalers now divide the frequency by
 926   (scaler_value + 1).
 927
 928 * MEC breakpoints are not checked during store operation
 929
 930
 931 version 1.5 14-09-95
 932 --------------------
 933
 934 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 935
 936 * Fixed bug that allowed an annuled instruction to cause memory exception.
 937
 938 * The *ws parameter in mem.c should now contain the number of waitstates
 939   required by the memory access (was total number of cycles).
 940
 941 * The supplied srt0.s now clears the BSS (thanks Joel).
 942
 943 version 1.4 22-08-95
 944 --------------------
 945
 946 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 947 some problems on solaris 2.x machines.
 948
 949 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 950 may suffer a bit ...
 951
 952 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 953
 954 version 1.3 26-07-95
 955 --------------------
 956
 957 * Fixed bug in mulscc instruction (how could that ever have worked?)
 958
 959 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 960
 961 version 1.2 13-07-95
 962 --------------------
 963
 964 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 965 one interrupt pending)
 966
 967 * Fixed updating of condition codes during logical instructions (carry and
 968 overflow were not reset)
 969
 970 * Fixed bug in WRTBR (tt field was wrongly over-written)
 971
 972 version 1.1 07-07-95
 973 --------------------
 974
 975 * Fixed several bugs in the interrupt handler and callback routines.
 976 (reported by Paul Warren, Alsys)
