 587 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 588
 589         * exec.c (dispatch_instruction):
 590         Correct the sense of the
 591                   if (!sparclite) {
 592                      sregs->trap = TRAP_UNIMP;
 593                      break;
 594                   }
 595         clause that has been pasted around: it's correct in the SCAN and
 596         DIVScc (divide step) cases (where it was probably originally
 597         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 598         ie. instructions only in the SPARC V8 or SPARClite 86x
 599         architectures.  It was also present when not required for SMUL,
 600         SMULcc, UMUL, UMULcc instructions that are present in all
 601         architectures.
 602
 603 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 604
 605         * interf.c (run_sim): Fix a bug in the main loop's handling of
 606         annulled delay slot instructions.  There is precedent for this
 607         change; the _other_ main loop in sis.c gets it right according to
 608         my reading of the code.
 609
 610         The bug is: if an interrupt happens when the next instruction
 611         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 612         with the current values of PC and NPC, so when the trap returns,
 613         the annulled instruction is indeed executed.  Another giveaway is
 614         that the annul flag is cleared in execute_trap(): the information
 615         is demonstrably discarded.
 616
 617         The solution is: perform annulling before looking for traps, in
 618         fact it's neater to do annulling, see if there's an interrupt and
 619         if not, do the instruction, then handle traps be they generated by
 620         interrupts pending or by the instruction we might just have done.
 621         That's what the sis.c one does.
 622
 623 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 624
 625         * sis.h: Add asr17 register for support of SparcLITE (at least the
 626         Hitachi ones I find before me)
 627
 628         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 629         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 630         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 631         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 632         (init_regs): Initialize y and asr17.
 633         NB: In instruction-set space, the Y register is asr0; the
 634         instructions have different names for human reasons only.
 635
 636         * sis.c:
 637         * interf.c: Set boolean mode variable dumbio if invoked with
 638         argument "-dumbio" and mention it of verbose.
 639         * erc32.c: if "dumbio" is set, do not assume that there is a
 640         terminal type device attached to stdin/stdout.  Do not set
 641         buffering or mess with tcsetattr or do any read operations in
 642         order to make UART interrupts; not input data is supported.
 643         This is necessary to allow the sim to be used within the eCos
 644         testing infrastructure where stdin/stdout are pipes to a TCL
 645         program; the sim hangs otherwise.

 669         emulating RAM found on typical SPARClite boards.  Print
 670         error message for unrecognized option.

 672         to allow emulation of SPARClite board RAM.

1052         byte.
1053
1054 Version 2.1 26-02-96
1055 --------------------
1056
1057 * Fixed bug in "go" command.
1058
1059 version 2.0 05-02-96
1060 --------------------
1061
1062 * Fixed bug in interrupt force register (erc32.c).
1063
1064 * Change file load function to use bfd_openr.
1065
1066 * SIS should now be endian independent.
1067
1068 version 1.8 24-11-95
1069 --------------------
1070
1071 * Fixed FPU timing - some sequences of FPU instructions did not calculate
1072   the resource dependencies right.
1073
1074 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
1075   but no FPU trap is generated.
1076
1077 version 1.7.1 31-10-95
1078 --------------------
1079
1080 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1081   the FPU stays in execute mode.
1082
1083 * Corrected JMPL and RETT timing (these instructions takes two cycles).
1084
1085
1086 version 1.7 25-10-95
1087 --------------------
1088
1089 * Interrupt during annuled instruction corrupted return address - fixed.
1090
1091
1092 version 1.6.2 25-10-95
1093 --------------------
1094
1095 * Added -DFAST_UART to Makefile
1096
1097
1098 version 1.6.1 24-10-95
1099 --------------------
1100
1101 * Fixed bug in STDFQ which caused bus error
1102
1103
1104 version 1.6 02-10-95
1105 --------------------
1106
1107 * Modified srt0.s to include code that initiates registers in IU and FPU
1108   and initializes the data segment. The simulator 'load' command does not
1109   longer initialize the data segment!
1110
1111 * Corrected MEC timer operation; scalers now divide the frequency by
1112   (scaler_value + 1).
1113
1114 * MEC breakpoints are not checked during store operation
1115
1116
1117 version 1.5 14-09-95
1118 --------------------
1119
1120 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1121
1122 * Fixed bug that allowed an annuled instruction to cause memory exception.
1123
1124 * The *ws parameter in mem.c should now contain the number of waitstates
1125   required by the memory access (was total number of cycles).
1126
1127 * The supplied srt0.s now clears the BSS (thanks Joel).
1128
1129 version 1.4 22-08-95
1130 --------------------
1131
1132 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1133 some problems on solaris 2.x machines.
1134
1135 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1136 may suffer a bit ...
1137
1138 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1139
1140 version 1.3 26-07-95
1141 --------------------
1142
1143 * Fixed bug in mulscc instruction (how could that ever have worked?)
1144
1145 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1146
1147 version 1.2 13-07-95
1148 --------------------
1149
1150 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1151 one interrupt pending)
1152
1153 * Fixed updating of condition codes during logical instructions (carry and
1154 overflow were not reset)
1155
1156 * Fixed bug in WRTBR (tt field was wrongly over-written)
1157
1158 version 1.1 07-07-95
1159 --------------------
1160
1161 * Fixed several bugs in the interrupt handler and callback routines.
1162 (reported by Paul Warren, Alsys)
