 555 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 556
 557         * exec.c (dispatch_instruction):
 558         Correct the sense of the
 559                   if (!sparclite) {
 560                      sregs->trap = TRAP_UNIMP;
 561                      break;
 562                   }
 563         clause that has been pasted around: it's correct in the SCAN and
 564         DIVScc (divide step) cases (where it was probably originally
 565         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 566         ie. instructions only in the SPARC V8 or SPARClite 86x
 567         architectures.  It was also present when not required for SMUL,
 568         SMULcc, UMUL, UMULcc instructions that are present in all
 569         architectures.
 570
 571 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 572
 573         * interf.c (run_sim): Fix a bug in the main loop's handling of
 574         annulled delay slot instructions.  There is precedent for this
 575         change; the _other_ main loop in sis.c gets it right according to
 576         my reading of the code.
 577
 578         The bug is: if an interrupt happens when the next instruction
 579         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 580         with the current values of PC and NPC, so when the trap returns,
 581         the annulled instruction is indeed executed.  Another giveaway is
 582         that the annul flag is cleared in execute_trap(): the information
 583         is demonstrably discarded.
 584
 585         The solution is: perform annulling before looking for traps, in
 586         fact it's neater to do annulling, see if there's an interrupt and
 587         if not, do the instruction, then handle traps be they generated by
 588         interrupts pending or by the instruction we might just have done.
 589         That's what the sis.c one does.
 590
 591 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 592
 593         * sis.h: Add asr17 register for support of SparcLITE (at least the
 594         Hitachi ones I find before me)
 595
 596         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 597         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 598         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 599         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 600         (init_regs): Initialize y and asr17.
 601         NB: In instruction-set space, the Y register is asr0; the
 602         instructions have different names for human reasons only.
 603
 604         * sis.c:
 605         * interf.c: Set boolean mode variable dumbio if invoked with
 606         argument "-dumbio" and mention it of verbose.
 607         * erc32.c: if "dumbio" is set, do not assume that there is a
 608         terminal type device attached to stdin/stdout.  Do not set
 609         buffering or mess with tcsetattr or do any read operations in
 610         order to make UART interrupts; not input data is supported.
 611         This is necessary to allow the sim to be used within the eCos
 612         testing infrastructure where stdin/stdout are pipes to a TCL
 613         program; the sim hangs otherwise.

 638         error message for unrecognized option.

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

1020         byte.
1021
1022 Version 2.1 26-02-96
1023 --------------------
1024
1025 * Fixed bug in "go" command.
1026
1027 version 2.0 05-02-96
1028 --------------------
1029
1030 * Fixed bug in interrupt force register (erc32.c).
1031
1032 * Change file load function to use bfd_openr.
1033
1034 * SIS should now be endian independent.
1035
1036 version 1.8 24-11-95
1037 --------------------
1038
1039 * Fixed FPU timing - some sequences of FPU instructions did not calculate
1040   the resource dependencies right.
1041
1042 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
1043   but no FPU trap is generated.
1044
1045 version 1.7.1 31-10-95
1046 --------------------
1047
1048 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1049   the FPU stays in execute mode.
1050
1051 * Corrected JMPL and RETT timing (these instructions takes two cycles).
1052
1053
1054 version 1.7 25-10-95
1055 --------------------
1056
1057 * Interrupt during annuled instruction corrupted return address - fixed.
1058
1059
1060 version 1.6.2 25-10-95
1061 --------------------
1062
1063 * Added -DFAST_UART to Makefile
1064
1065
1066 version 1.6.1 24-10-95
1067 --------------------
1068
1069 * Fixed bug in STDFQ which caused bus error
1070
1071
1072 version 1.6 02-10-95
1073 --------------------
1074
1075 * Modified srt0.s to include code that initiates registers in IU and FPU
1076   and initializes the data segment. The simulator 'load' command does not
1077   longer initialize the data segment!
1078
1079 * Corrected MEC timer operation; scalers now divide the frequency by
1080   (scaler_value + 1).
1081
1082 * MEC breakpoints are not checked during store operation
1083
1084
1085 version 1.5 14-09-95
1086 --------------------
1087
1088 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1089
1090 * Fixed bug that allowed an annuled instruction to cause memory exception.
1091
1092 * The *ws parameter in mem.c should now contain the number of waitstates
1093   required by the memory access (was total number of cycles).
1094
1095 * The supplied srt0.s now clears the BSS (thanks Joel).
1096
1097 version 1.4 22-08-95
1098 --------------------
1099
1100 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1101 some problems on solaris 2.x machines.
1102
1103 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1104 may suffer a bit ...
1105
1106 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1107
1108 version 1.3 26-07-95
1109 --------------------
1110
1111 * Fixed bug in mulscc instruction (how could that ever have worked?)
1112
1113 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1114
1115 version 1.2 13-07-95
1116 --------------------
1117
1118 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1119 one interrupt pending)
1120
1121 * Fixed updating of condition codes during logical instructions (carry and
1122 overflow were not reset)
1123
1124 * Fixed bug in WRTBR (tt field was wrongly over-written)
1125
1126 version 1.1 07-07-95
1127 --------------------
1128
1129 * Fixed several bugs in the interrupt handler and callback routines.
1130 (reported by Paul Warren, Alsys)
