 520 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 521
 522         * exec.c (dispatch_instruction):
 523         Correct the sense of the
 524                   if (!sparclite) {
 525                      sregs->trap = TRAP_UNIMP;
 526                      break;
 527                   }
 528         clause that has been pasted around: it's correct in the SCAN and
 529         DIVScc (divide step) cases (where it was probably originally
 530         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 531         ie. instructions only in the SPARC V8 or SPARClite 86x
 532         architectures.  It was also present when not required for SMUL,
 533         SMULcc, UMUL, UMULcc instructions that are present in all
 534         architectures.
 535
 536 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 537
 538         * interf.c (run_sim): Fix a bug in the main loop's handling of
 539         annulled delay slot instructions.  There is precedent for this
 540         change; the _other_ main loop in sis.c gets it right according to
 541         my reading of the code.
 542
 543         The bug is: if an interrupt happens when the next instruction
 544         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 545         with the current values of PC and NPC, so when the trap returns,
 546         the annulled instruction is indeed executed.  Another giveaway is
 547         that the annul flag is cleared in execute_trap(): the information
 548         is demonstrably discarded.
 549
 550         The solution is: perform annulling before looking for traps, in
 551         fact it's neater to do annulling, see if there's an interrupt and
 552         if not, do the instruction, then handle traps be they generated by
 553         interrupts pending or by the instruction we might just have done.
 554         That's what the sis.c one does.
 555
 556 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 557
 558         * sis.h: Add asr17 register for support of SparcLITE (at least the
 559         Hitachi ones I find before me)
 560
 561         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 562         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 563         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 564         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 565         (init_regs): Initialize y and asr17.
 566         NB: In instruction-set space, the Y register is asr0; the
 567         instructions have different names for human reasons only.
 568
 569         * sis.c:
 570         * interf.c: Set boolean mode variable dumbio if invoked with
 571         argument "-dumbio" and mention it of verbose.
 572         * erc32.c: if "dumbio" is set, do not assume that there is a
 573         terminal type device attached to stdin/stdout.  Do not set
 574         buffering or mess with tcsetattr or do any read operations in
 575         order to make UART interrupts; not input data is supported.
 576         This is necessary to allow the sim to be used within the eCos
 577         testing infrastructure where stdin/stdout are pipes to a TCL
 578         program; the sim hangs otherwise.
 579
 580 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>

 602         emulating RAM found on typical SPARClite boards.  Print
 603         error message for unrecognized option.

 611         (get_mem_ptr): Remove unnecessary byte parameter.

 986
 987 Version 2.1 26-02-96
 988 --------------------
 989
 990 * Fixed bug in "go" command.
 991
 992 version 2.0 05-02-96
 993 --------------------
 994
 995 * Fixed bug in interrupt force register (erc32.c).
 996
 997 * Change file load function to use bfd_openr.
 998
 999 * SIS should now be endian independent.
1000
1001 version 1.8 24-11-95
1002 --------------------
1003
1004 * Fixed FPU timing - some sequences of FPU instructions did not calculate
1005   the resource dependencies right.
1006
1007 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
1008   but no FPU trap is generated.
1009
1010 version 1.7.1 31-10-95
1011 --------------------
1012
1013 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1014   the FPU stays in execute mode.
1015
1016 * Corrected JMPL and RETT timing (these instructions takes two cycles).
1017
1018
1019 version 1.7 25-10-95
1020 --------------------
1021
1022 * Interrupt during annuled instruction corrupted return address - fixed.
1023
1024
1025 version 1.6.2 25-10-95
1026 --------------------
1027
1028 * Added -DFAST_UART to Makefile
1029
1030
1031 version 1.6.1 24-10-95
1032 --------------------
1033
1034 * Fixed bug in STDFQ which caused bus error
1035
1036
1037 version 1.6 02-10-95
1038 --------------------
1039
1040 * Modified srt0.s to include code that initiates registers in IU and FPU
1041   and initializes the data segment. The simulator 'load' command does not
1042   longer initialize the data segment!
1043
1044 * Corrected MEC timer operation; scalers now divide the frequency by
1045   (scaler_value + 1).
1046
1047 * MEC breakpoints are not checked during store operation
1048
1049
1050 version 1.5 14-09-95
1051 --------------------
1052
1053 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1054
1055 * Fixed bug that allowed an annuled instruction to cause memory exception.
1056
1057 * The *ws parameter in mem.c should now contain the number of waitstates
1058   required by the memory access (was total number of cycles).
1059
1060 * The supplied srt0.s now clears the BSS (thanks Joel).
1061
1062 version 1.4 22-08-95
1063 --------------------
1064
1065 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1066 some problems on solaris 2.x machines.
1067
1068 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1069 may suffer a bit ...
1070
1071 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1072
1073 version 1.3 26-07-95
1074 --------------------
1075
1076 * Fixed bug in mulscc instruction (how could that ever have worked?)
1077
1078 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1079
1080 version 1.2 13-07-95
1081 --------------------
1082
1083 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1084 one interrupt pending)
1085
1086 * Fixed updating of condition codes during logical instructions (carry and
1087 overflow were not reset)
1088
1089 * Fixed bug in WRTBR (tt field was wrongly over-written)
1090
1091 version 1.1 07-07-95
1092 --------------------
1093
1094 * Fixed several bugs in the interrupt handler and callback routines.
1095 (reported by Paul Warren, Alsys)
