 496 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 497
 498         * exec.c (dispatch_instruction):
 499         Correct the sense of the
 500                   if (!sparclite) {
 501                      sregs->trap = TRAP_UNIMP;
 502                      break;
 503                   }
 504         clause that has been pasted around: it's correct in the SCAN and
 505         DIVScc (divide step) cases (where it was probably originally
 506         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 507         ie. instructions only in the SPARC V8 or SPARClite 86x
 508         architectures.  It was also present when not required for SMUL,
 509         SMULcc, UMUL, UMULcc instructions that are present in all
 510         architectures.
 511
 512 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 513
 514         * interf.c (run_sim): Fix a bug in the main loop's handling of
 515         annulled delay slot instructions.  There is precedent for this
 516         change; the _other_ main loop in sis.c gets it right according to
 517         my reading of the code.
 518
 519         The bug is: if an interrupt happens when the next instruction
 520         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 521         with the current values of PC and NPC, so when the trap returns,
 522         the annulled instruction is indeed executed.  Another giveaway is
 523         that the annul flag is cleared in execute_trap(): the information
 524         is demonstrably discarded.
 525
 526         The solution is: perform annulling before looking for traps, in
 527         fact it's neater to do annulling, see if there's an interrupt and
 528         if not, do the instruction, then handle traps be they generated by
 529         interrupts pending or by the instruction we might just have done.
 530         That's what the sis.c one does.
 531
 532 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 533
 534         * sis.h: Add asr17 register for support of SparcLITE (at least the
 535         Hitachi ones I find before me)
 536
 537         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 538         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 539         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 540         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 541         (init_regs): Initialize y and asr17.
 542         NB: In instruction-set space, the Y register is asr0; the
 543         instructions have different names for human reasons only.
 544
 545         * sis.c:
 546         * interf.c: Set boolean mode variable dumbio if invoked with
 547         argument "-dumbio" and mention it of verbose.
 548         * erc32.c: if "dumbio" is set, do not assume that there is a
 549         terminal type device attached to stdin/stdout.  Do not set
 550         buffering or mess with tcsetattr or do any read operations in
 551         order to make UART interrupts; not input data is supported.
 552         This is necessary to allow the sim to be used within the eCos
 553         testing infrastructure where stdin/stdout are pipes to a TCL
 554         program; the sim hangs otherwise.
 555
 556 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>

 577         byte-swapping unnecessary.  Add -sparclite-board option for
 578         emulating RAM found on typical SPARClite boards.  Print
 579         error message for unrecognized option.
 580         * erc32.c: Change RAM address and size from constants to variables,
 581         to allow emulation of SPARClite board RAM.

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

 961         byte.
 962
 963 Version 2.1 26-02-96
 964 --------------------
 965
 966 * Fixed bug in "go" command.
 967
 968 version 2.0 05-02-96
 969 --------------------
 970
 971 * Fixed bug in interrupt force register (erc32.c).
 972
 973 * Change file load function to use bfd_openr.
 974
 975 * SIS should now be endian independent.
 976
 977 version 1.8 24-11-95
 978 --------------------
 979
 980 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 981   the resource dependencies right.
 982
 983 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 984   but no FPU trap is generated.
 985
 986 version 1.7.1 31-10-95
 987 --------------------
 988
 989 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 990   the FPU stays in execute mode.
 991
 992 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 993
 994
 995 version 1.7 25-10-95
 996 --------------------
 997
 998 * Interrupt during annuled instruction corrupted return address - fixed.
 999
1000
1001 version 1.6.2 25-10-95
1002 --------------------
1003
1004 * Added -DFAST_UART to Makefile
1005
1006
1007 version 1.6.1 24-10-95
1008 --------------------
1009
1010 * Fixed bug in STDFQ which caused bus error
1011
1012
1013 version 1.6 02-10-95
1014 --------------------
1015
1016 * Modified srt0.s to include code that initiates registers in IU and FPU
1017   and initializes the data segment. The simulator 'load' command does not
1018   longer initialize the data segment!
1019
1020 * Corrected MEC timer operation; scalers now divide the frequency by
1021   (scaler_value + 1).
1022
1023 * MEC breakpoints are not checked during store operation
1024
1025
1026 version 1.5 14-09-95
1027 --------------------
1028
1029 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1030
1031 * Fixed bug that allowed an annuled instruction to cause memory exception.
1032
1033 * The *ws parameter in mem.c should now contain the number of waitstates
1034   required by the memory access (was total number of cycles).
1035
1036 * The supplied srt0.s now clears the BSS (thanks Joel).
1037
1038 version 1.4 22-08-95
1039 --------------------
1040
1041 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1042 some problems on solaris 2.x machines.
1043
1044 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1045 may suffer a bit ...
1046
1047 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1048
1049 version 1.3 26-07-95
1050 --------------------
1051
1052 * Fixed bug in mulscc instruction (how could that ever have worked?)
1053
1054 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1055
1056 version 1.2 13-07-95
1057 --------------------
1058
1059 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1060 one interrupt pending)
1061
1062 * Fixed updating of condition codes during logical instructions (carry and
1063 overflow were not reset)
1064
1065 * Fixed bug in WRTBR (tt field was wrongly over-written)
1066
1067 version 1.1 07-07-95
1068 --------------------
1069
1070 * Fixed several bugs in the interrupt handler and callback routines.
1071 (reported by Paul Warren, Alsys)
