 546 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>

 549         Correct the sense of the
 550                   if (!sparclite) {
 551                      sregs->trap = TRAP_UNIMP;
 552                      break;
 553                   }
 554         clause that has been pasted around: it's correct in the SCAN and
 555         DIVScc (divide step) cases (where it was probably originally
 556         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 557         ie. instructions only in the SPARC V8 or SPARClite 86x
 558         architectures.  It was also present when not required for SMUL,
 559         SMULcc, UMUL, UMULcc instructions that are present in all
 560         architectures.
 561
 562 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 563
 564         * interf.c (run_sim): Fix a bug in the main loop's handling of
 565         annulled delay slot instructions.  There is precedent for this
 566         change; the _other_ main loop in sis.c gets it right according to
 567         my reading of the code.
 568
 569         The bug is: if an interrupt happens when the next instruction
 570         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 571         with the current values of PC and NPC, so when the trap returns,
 572         the annulled instruction is indeed executed.  Another giveaway is
 573         that the annul flag is cleared in execute_trap(): the information
 574         is demonstrably discarded.
 575
 576         The solution is: perform annulling before looking for traps, in
 577         fact it's neater to do annulling, see if there's an interrupt and
 578         if not, do the instruction, then handle traps be they generated by
 579         interrupts pending or by the instruction we might just have done.
 580         That's what the sis.c one does.
 581
 582 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 583
 584         * sis.h: Add asr17 register for support of SparcLITE (at least the
 585         Hitachi ones I find before me)
 586
 587         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 588         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 589         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 590         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 591         (init_regs): Initialize y and asr17.
 592         NB: In instruction-set space, the Y register is asr0; the
 593         instructions have different names for human reasons only.
 594
 595         * sis.c:
 596         * interf.c: Set boolean mode variable dumbio if invoked with
 597         argument "-dumbio" and mention it of verbose.
 598         * erc32.c: if "dumbio" is set, do not assume that there is a
 599         terminal type device attached to stdin/stdout.  Do not set
 600         buffering or mess with tcsetattr or do any read operations in
 601         order to make UART interrupts; not input data is supported.
 602         This is necessary to allow the sim to be used within the eCos
 603         testing infrastructure where stdin/stdout are pipes to a TCL
 604         program; the sim hangs otherwise.

 637         (get_mem_ptr): Remove unnecessary byte parameter.

 645         * exec.c (dispatch_instruction): Use revamped memory_read, which

1011         byte.
1012
1013 Version 2.1 26-02-96
1014 --------------------
1015
1016 * Fixed bug in "go" command.
1017
1018 version 2.0 05-02-96
1019 --------------------
1020
1021 * Fixed bug in interrupt force register (erc32.c).
1022
1023 * Change file load function to use bfd_openr.
1024
1025 * SIS should now be endian independent.
1026
1027 version 1.8 24-11-95
1028 --------------------
1029
1030 * Fixed FPU timing - some sequences of FPU instructions did not calculate
1031   the resource dependencies right.
1032
1033 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
1034   but no FPU trap is generated.
1035
1036 version 1.7.1 31-10-95
1037 --------------------
1038
1039 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1040   the FPU stays in execute mode.
1041
1042 * Corrected JMPL and RETT timing (these instructions takes two cycles).
1043
1044
1045 version 1.7 25-10-95
1046 --------------------
1047
1048 * Interrupt during annuled instruction corrupted return address - fixed.
1049
1050
1051 version 1.6.2 25-10-95
1052 --------------------
1053
1054 * Added -DFAST_UART to Makefile
1055
1056
1057 version 1.6.1 24-10-95
1058 --------------------
1059
1060 * Fixed bug in STDFQ which caused bus error
1061
1062
1063 version 1.6 02-10-95
1064 --------------------
1065
1066 * Modified srt0.s to include code that initiates registers in IU and FPU
1067   and initializes the data segment. The simulator 'load' command does not
1068   longer initialize the data segment!
1069
1070 * Corrected MEC timer operation; scalers now divide the frequency by
1071   (scaler_value + 1).
1072
1073 * MEC breakpoints are not checked during store operation
1074
1075
1076 version 1.5 14-09-95
1077 --------------------
1078
1079 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1080
1081 * Fixed bug that allowed an annuled instruction to cause memory exception.
1082
1083 * The *ws parameter in mem.c should now contain the number of waitstates
1084   required by the memory access (was total number of cycles).
1085
1086 * The supplied srt0.s now clears the BSS (thanks Joel).
1087
1088 version 1.4 22-08-95
1089 --------------------
1090
1091 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1092 some problems on solaris 2.x machines.
1093
1094 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1095 may suffer a bit ...
1096
1097 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1098
1099 version 1.3 26-07-95
1100 --------------------
1101
1102 * Fixed bug in mulscc instruction (how could that ever have worked?)
1103
1104 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1105
1106 version 1.2 13-07-95
1107 --------------------
1108
1109 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1110 one interrupt pending)
1111
1112 * Fixed updating of condition codes during logical instructions (carry and
1113 overflow were not reset)
1114
1115 * Fixed bug in WRTBR (tt field was wrongly over-written)
1116
1117 version 1.1 07-07-95
1118 --------------------
1119
1120 * Fixed several bugs in the interrupt handler and callback routines.
1121 (reported by Paul Warren, Alsys)
