 528 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 529
 530         * exec.c (dispatch_instruction):
 531         Correct the sense of the
 532                   if (!sparclite) {
 533                      sregs->trap = TRAP_UNIMP;
 534                      break;
 535                   }
 536         clause that has been pasted around: it's correct in the SCAN and
 537         DIVScc (divide step) cases (where it was probably originally
 538         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 539         ie. instructions only in the SPARC V8 or SPARClite 86x
 540         architectures.  It was also present when not required for SMUL,
 541         SMULcc, UMUL, UMULcc instructions that are present in all
 542         architectures.
 543
 544 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 545
 546         * interf.c (run_sim): Fix a bug in the main loop's handling of
 547         annulled delay slot instructions.  There is precedent for this
 548         change; the _other_ main loop in sis.c gets it right according to
 549         my reading of the code.
 550
 551         The bug is: if an interrupt happens when the next instruction
 552         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 553         with the current values of PC and NPC, so when the trap returns,
 554         the annulled instruction is indeed executed.  Another giveaway is
 555         that the annul flag is cleared in execute_trap(): the information
 556         is demonstrably discarded.
 557
 558         The solution is: perform annulling before looking for traps, in
 559         fact it's neater to do annulling, see if there's an interrupt and
 560         if not, do the instruction, then handle traps be they generated by
 561         interrupts pending or by the instruction we might just have done.
 562         That's what the sis.c one does.
 563
 564 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 565
 566         * sis.h: Add asr17 register for support of SparcLITE (at least the
 567         Hitachi ones I find before me)
 568
 569         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 570         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 571         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 572         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 573         (init_regs): Initialize y and asr17.
 574         NB: In instruction-set space, the Y register is asr0; the
 575         instructions have different names for human reasons only.
 576
 577         * sis.c:
 578         * interf.c: Set boolean mode variable dumbio if invoked with
 579         argument "-dumbio" and mention it of verbose.
 580         * erc32.c: if "dumbio" is set, do not assume that there is a
 581         terminal type device attached to stdin/stdout.  Do not set
 582         buffering or mess with tcsetattr or do any read operations in
 583         order to make UART interrupts; not input data is supported.
 584         This is necessary to allow the sim to be used within the eCos
 585         testing infrastructure where stdin/stdout are pipes to a TCL
 586         program; the sim hangs otherwise.
 587
 588 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>

 609         byte-swapping unnecessary.  Add -sparclite-board option for
 610         emulating RAM found on typical SPARClite boards.  Print
 611         error message for unrecognized option.

 993         byte.
 994
 995 Version 2.1 26-02-96
 996 --------------------
 997
 998 * Fixed bug in "go" command.
 999
1000 version 2.0 05-02-96
1001 --------------------
1002
1003 * Fixed bug in interrupt force register (erc32.c).
1004
1005 * Change file load function to use bfd_openr.
1006
1007 * SIS should now be endian independent.
1008
1009 version 1.8 24-11-95
1010 --------------------
1011
1012 * Fixed FPU timing - some sequences of FPU instructions did not calculate
1013   the resource dependencies right.
1014
1015 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
1016   but no FPU trap is generated.
1017
1018 version 1.7.1 31-10-95
1019 --------------------
1020
1021 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1022   the FPU stays in execute mode.
1023
1024 * Corrected JMPL and RETT timing (these instructions takes two cycles).
1025
1026
1027 version 1.7 25-10-95
1028 --------------------
1029
1030 * Interrupt during annuled instruction corrupted return address - fixed.
1031
1032
1033 version 1.6.2 25-10-95
1034 --------------------
1035
1036 * Added -DFAST_UART to Makefile
1037
1038
1039 version 1.6.1 24-10-95
1040 --------------------
1041
1042 * Fixed bug in STDFQ which caused bus error
1043
1044
1045 version 1.6 02-10-95
1046 --------------------
1047
1048 * Modified srt0.s to include code that initiates registers in IU and FPU
1049   and initializes the data segment. The simulator 'load' command does not
1050   longer initialize the data segment!
1051
1052 * Corrected MEC timer operation; scalers now divide the frequency by
1053   (scaler_value + 1).
1054
1055 * MEC breakpoints are not checked during store operation
1056
1057
1058 version 1.5 14-09-95
1059 --------------------
1060
1061 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1062
1063 * Fixed bug that allowed an annuled instruction to cause memory exception.
1064
1065 * The *ws parameter in mem.c should now contain the number of waitstates
1066   required by the memory access (was total number of cycles).
1067
1068 * The supplied srt0.s now clears the BSS (thanks Joel).
1069
1070 version 1.4 22-08-95
1071 --------------------
1072
1073 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1074 some problems on solaris 2.x machines.
1075
1076 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1077 may suffer a bit ...
1078
1079 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1080
1081 version 1.3 26-07-95
1082 --------------------
1083
1084 * Fixed bug in mulscc instruction (how could that ever have worked?)
1085
1086 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1087
1088 version 1.2 13-07-95
1089 --------------------
1090
1091 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1092 one interrupt pending)
1093
1094 * Fixed updating of condition codes during logical instructions (carry and
1095 overflow were not reset)
1096
1097 * Fixed bug in WRTBR (tt field was wrongly over-written)
1098
1099 version 1.1 07-07-95
1100 --------------------
1101
1102 * Fixed several bugs in the interrupt handler and callback routines.
1103 (reported by Paul Warren, Alsys)
