 573 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 574

 576         Correct the sense of the
 577                   if (!sparclite) {
 578                      sregs->trap = TRAP_UNIMP;
 579                      break;
 580                   }
 581         clause that has been pasted around: it's correct in the SCAN and
 582         DIVScc (divide step) cases (where it was probably originally
 583         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 584         ie. instructions only in the SPARC V8 or SPARClite 86x
 585         architectures.  It was also present when not required for SMUL,
 586         SMULcc, UMUL, UMULcc instructions that are present in all
 587         architectures.
 588
 589 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 590
 591         * interf.c (run_sim): Fix a bug in the main loop's handling of
 592         annulled delay slot instructions.  There is precedent for this
 593         change; the _other_ main loop in sis.c gets it right according to
 594         my reading of the code.
 595
 596         The bug is: if an interrupt happens when the next instruction
 597         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 598         with the current values of PC and NPC, so when the trap returns,
 599         the annulled instruction is indeed executed.  Another giveaway is
 600         that the annul flag is cleared in execute_trap(): the information
 601         is demonstrably discarded.
 602
 603         The solution is: perform annulling before looking for traps, in
 604         fact it's neater to do annulling, see if there's an interrupt and
 605         if not, do the instruction, then handle traps be they generated by
 606         interrupts pending or by the instruction we might just have done.
 607         That's what the sis.c one does.
 608
 609 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 610
 611         * sis.h: Add asr17 register for support of SparcLITE (at least the
 612         Hitachi ones I find before me)
 613
 614         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 615         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 616         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 617         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 618         (init_regs): Initialize y and asr17.
 619         NB: In instruction-set space, the Y register is asr0; the
 620         instructions have different names for human reasons only.
 621
 622         * sis.c:
 623         * interf.c: Set boolean mode variable dumbio if invoked with
 624         argument "-dumbio" and mention it of verbose.
 625         * erc32.c: if "dumbio" is set, do not assume that there is a
 626         terminal type device attached to stdin/stdout.  Do not set
 627         buffering or mess with tcsetattr or do any read operations in
 628         order to make UART interrupts; not input data is supported.
 629         This is necessary to allow the sim to be used within the eCos
 630         testing infrastructure where stdin/stdout are pipes to a TCL
 631         program; the sim hangs otherwise.

 656         error message for unrecognized option.

1038         byte.
1039
1040 Version 2.1 26-02-96
1041 --------------------
1042
1043 * Fixed bug in "go" command.
1044
1045 version 2.0 05-02-96
1046 --------------------
1047
1048 * Fixed bug in interrupt force register (erc32.c).
1049
1050 * Change file load function to use bfd_openr.
1051
1052 * SIS should now be endian independent.
1053
1054 version 1.8 24-11-95
1055 --------------------
1056
1057 * Fixed FPU timing - some sequences of FPU instructions did not calculate
1058   the resource dependencies right.
1059
1060 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
1061   but no FPU trap is generated.
1062
1063 version 1.7.1 31-10-95
1064 --------------------
1065
1066 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1067   the FPU stays in execute mode.
1068
1069 * Corrected JMPL and RETT timing (these instructions takes two cycles).
1070
1071
1072 version 1.7 25-10-95
1073 --------------------
1074
1075 * Interrupt during annuled instruction corrupted return address - fixed.
1076
1077
1078 version 1.6.2 25-10-95
1079 --------------------
1080
1081 * Added -DFAST_UART to Makefile
1082
1083
1084 version 1.6.1 24-10-95
1085 --------------------
1086
1087 * Fixed bug in STDFQ which caused bus error
1088
1089
1090 version 1.6 02-10-95
1091 --------------------
1092
1093 * Modified srt0.s to include code that initiates registers in IU and FPU
1094   and initializes the data segment. The simulator 'load' command does not
1095   longer initialize the data segment!
1096
1097 * Corrected MEC timer operation; scalers now divide the frequency by
1098   (scaler_value + 1).
1099
1100 * MEC breakpoints are not checked during store operation
1101
1102
1103 version 1.5 14-09-95
1104 --------------------
1105
1106 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1107
1108 * Fixed bug that allowed an annuled instruction to cause memory exception.
1109
1110 * The *ws parameter in mem.c should now contain the number of waitstates
1111   required by the memory access (was total number of cycles).
1112
1113 * The supplied srt0.s now clears the BSS (thanks Joel).
1114
1115 version 1.4 22-08-95
1116 --------------------
1117
1118 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1119 some problems on solaris 2.x machines.
1120
1121 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1122 may suffer a bit ...
1123
1124 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1125
1126 version 1.3 26-07-95
1127 --------------------
1128
1129 * Fixed bug in mulscc instruction (how could that ever have worked?)
1130
1131 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1132
1133 version 1.2 13-07-95
1134 --------------------
1135
1136 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1137 one interrupt pending)
1138
1139 * Fixed updating of condition codes during logical instructions (carry and
1140 overflow were not reset)
1141
1142 * Fixed bug in WRTBR (tt field was wrongly over-written)
1143
1144 version 1.1 07-07-95
1145 --------------------
1146
1147 * Fixed several bugs in the interrupt handler and callback routines.
1148 (reported by Paul Warren, Alsys)
