 578 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 579
 580         * exec.c (dispatch_instruction):
 581         Correct the sense of the
 582                   if (!sparclite) {
 583                      sregs->trap = TRAP_UNIMP;
 584                      break;
 585                   }
 586         clause that has been pasted around: it's correct in the SCAN and
 587         DIVScc (divide step) cases (where it was probably originally
 588         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 589         ie. instructions only in the SPARC V8 or SPARClite 86x
 590         architectures.  It was also present when not required for SMUL,
 591         SMULcc, UMUL, UMULcc instructions that are present in all
 592         architectures.
 593
 594 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 595
 596         * interf.c (run_sim): Fix a bug in the main loop's handling of
 597         annulled delay slot instructions.  There is precedent for this
 598         change; the _other_ main loop in sis.c gets it right according to
 599         my reading of the code.
 600
 601         The bug is: if an interrupt happens when the next instruction
 602         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 603         with the current values of PC and NPC, so when the trap returns,
 604         the annulled instruction is indeed executed.  Another giveaway is
 605         that the annul flag is cleared in execute_trap(): the information
 606         is demonstrably discarded.
 607
 608         The solution is: perform annulling before looking for traps, in
 609         fact it's neater to do annulling, see if there's an interrupt and
 610         if not, do the instruction, then handle traps be they generated by
 611         interrupts pending or by the instruction we might just have done.
 612         That's what the sis.c one does.
 613
 614 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 615
 616         * sis.h: Add asr17 register for support of SparcLITE (at least the
 617         Hitachi ones I find before me)
 618
 619         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 620         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 621         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 622         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 623         (init_regs): Initialize y and asr17.
 624         NB: In instruction-set space, the Y register is asr0; the
 625         instructions have different names for human reasons only.
 626
 627         * sis.c:
 628         * interf.c: Set boolean mode variable dumbio if invoked with
 629         argument "-dumbio" and mention it of verbose.
 630         * erc32.c: if "dumbio" is set, do not assume that there is a
 631         terminal type device attached to stdin/stdout.  Do not set
 632         buffering or mess with tcsetattr or do any read operations in
 633         order to make UART interrupts; not input data is supported.
 634         This is necessary to allow the sim to be used within the eCos
 635         testing infrastructure where stdin/stdout are pipes to a TCL
 636         program; the sim hangs otherwise.

 660         emulating RAM found on typical SPARClite boards.  Print
 661         error message for unrecognized option.

1043         byte.
1044
1045 Version 2.1 26-02-96
1046 --------------------
1047
1048 * Fixed bug in "go" command.
1049
1050 version 2.0 05-02-96
1051 --------------------
1052
1053 * Fixed bug in interrupt force register (erc32.c).
1054
1055 * Change file load function to use bfd_openr.
1056
1057 * SIS should now be endian independent.
1058
1059 version 1.8 24-11-95
1060 --------------------
1061
1062 * Fixed FPU timing - some sequences of FPU instructions did not calculate
1063   the resource dependencies right.
1064
1065 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
1066   but no FPU trap is generated.
1067
1068 version 1.7.1 31-10-95
1069 --------------------
1070
1071 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1072   the FPU stays in execute mode.
1073
1074 * Corrected JMPL and RETT timing (these instructions takes two cycles).
1075
1076
1077 version 1.7 25-10-95
1078 --------------------
1079
1080 * Interrupt during annuled instruction corrupted return address - fixed.
1081
1082
1083 version 1.6.2 25-10-95
1084 --------------------
1085
1086 * Added -DFAST_UART to Makefile
1087
1088
1089 version 1.6.1 24-10-95
1090 --------------------
1091
1092 * Fixed bug in STDFQ which caused bus error
1093
1094
1095 version 1.6 02-10-95
1096 --------------------
1097
1098 * Modified srt0.s to include code that initiates registers in IU and FPU
1099   and initializes the data segment. The simulator 'load' command does not
1100   longer initialize the data segment!
1101
1102 * Corrected MEC timer operation; scalers now divide the frequency by
1103   (scaler_value + 1).
1104
1105 * MEC breakpoints are not checked during store operation
1106
1107
1108 version 1.5 14-09-95
1109 --------------------
1110
1111 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1112
1113 * Fixed bug that allowed an annuled instruction to cause memory exception.
1114
1115 * The *ws parameter in mem.c should now contain the number of waitstates
1116   required by the memory access (was total number of cycles).
1117
1118 * The supplied srt0.s now clears the BSS (thanks Joel).
1119
1120 version 1.4 22-08-95
1121 --------------------
1122
1123 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1124 some problems on solaris 2.x machines.
1125
1126 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1127 may suffer a bit ...
1128
1129 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1130
1131 version 1.3 26-07-95
1132 --------------------
1133
1134 * Fixed bug in mulscc instruction (how could that ever have worked?)
1135
1136 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1137
1138 version 1.2 13-07-95
1139 --------------------
1140
1141 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1142 one interrupt pending)
1143
1144 * Fixed updating of condition codes during logical instructions (carry and
1145 overflow were not reset)
1146
1147 * Fixed bug in WRTBR (tt field was wrongly over-written)
1148
1149 version 1.1 07-07-95
1150 --------------------
1151
1152 * Fixed several bugs in the interrupt handler and callback routines.
1153 (reported by Paul Warren, Alsys)
