 524 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 525
 526         * exec.c (dispatch_instruction):
 527         Correct the sense of the
 528                   if (!sparclite) {
 529                      sregs->trap = TRAP_UNIMP;
 530                      break;
 531                   }
 532         clause that has been pasted around: it's correct in the SCAN and
 533         DIVScc (divide step) cases (where it was probably originally
 534         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 535         ie. instructions only in the SPARC V8 or SPARClite 86x
 536         architectures.  It was also present when not required for SMUL,
 537         SMULcc, UMUL, UMULcc instructions that are present in all
 538         architectures.
 539
 540 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 541
 542         * interf.c (run_sim): Fix a bug in the main loop's handling of
 543         annulled delay slot instructions.  There is precedent for this
 544         change; the _other_ main loop in sis.c gets it right according to
 545         my reading of the code.
 546
 547         The bug is: if an interrupt happens when the next instruction
 548         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 549         with the current values of PC and NPC, so when the trap returns,
 550         the annulled instruction is indeed executed.  Another giveaway is
 551         that the annul flag is cleared in execute_trap(): the information
 552         is demonstrably discarded.
 553
 554         The solution is: perform annulling before looking for traps, in
 555         fact it's neater to do annulling, see if there's an interrupt and
 556         if not, do the instruction, then handle traps be they generated by
 557         interrupts pending or by the instruction we might just have done.
 558         That's what the sis.c one does.
 559
 560 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 561
 562         * sis.h: Add asr17 register for support of SparcLITE (at least the
 563         Hitachi ones I find before me)
 564
 565         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 566         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 567         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 568         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 569         (init_regs): Initialize y and asr17.
 570         NB: In instruction-set space, the Y register is asr0; the
 571         instructions have different names for human reasons only.
 572
 573         * sis.c:
 574         * interf.c: Set boolean mode variable dumbio if invoked with
 575         argument "-dumbio" and mention it of verbose.
 576         * erc32.c: if "dumbio" is set, do not assume that there is a
 577         terminal type device attached to stdin/stdout.  Do not set
 578         buffering or mess with tcsetattr or do any read operations in
 579         order to make UART interrupts; not input data is supported.
 580         This is necessary to allow the sim to be used within the eCos
 581         testing infrastructure where stdin/stdout are pipes to a TCL
 582         program; the sim hangs otherwise.

 606         emulating RAM found on typical SPARClite boards.  Print
 607         error message for unrecognized option.

 990
 991 Version 2.1 26-02-96
 992 --------------------
 993
 994 * Fixed bug in "go" command.
 995
 996 version 2.0 05-02-96
 997 --------------------
 998
 999 * Fixed bug in interrupt force register (erc32.c).
1000
1001 * Change file load function to use bfd_openr.
1002
1003 * SIS should now be endian independent.
1004
1005 version 1.8 24-11-95
1006 --------------------
1007
1008 * Fixed FPU timing - some sequences of FPU instructions did not calculate
1009   the resource dependencies right.
1010
1011 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
1012   but no FPU trap is generated.
1013
1014 version 1.7.1 31-10-95
1015 --------------------
1016
1017 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1018   the FPU stays in execute mode.
1019
1020 * Corrected JMPL and RETT timing (these instructions takes two cycles).
1021
1022
1023 version 1.7 25-10-95
1024 --------------------
1025
1026 * Interrupt during annuled instruction corrupted return address - fixed.
1027
1028
1029 version 1.6.2 25-10-95
1030 --------------------
1031
1032 * Added -DFAST_UART to Makefile
1033
1034
1035 version 1.6.1 24-10-95
1036 --------------------
1037
1038 * Fixed bug in STDFQ which caused bus error
1039
1040
1041 version 1.6 02-10-95
1042 --------------------
1043
1044 * Modified srt0.s to include code that initiates registers in IU and FPU
1045   and initializes the data segment. The simulator 'load' command does not
1046   longer initialize the data segment!
1047
1048 * Corrected MEC timer operation; scalers now divide the frequency by
1049   (scaler_value + 1).
1050
1051 * MEC breakpoints are not checked during store operation
1052
1053
1054 version 1.5 14-09-95
1055 --------------------
1056
1057 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1058
1059 * Fixed bug that allowed an annuled instruction to cause memory exception.
1060
1061 * The *ws parameter in mem.c should now contain the number of waitstates
1062   required by the memory access (was total number of cycles).
1063
1064 * The supplied srt0.s now clears the BSS (thanks Joel).
1065
1066 version 1.4 22-08-95
1067 --------------------
1068
1069 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1070 some problems on solaris 2.x machines.
1071
1072 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1073 may suffer a bit ...
1074
1075 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1076
1077 version 1.3 26-07-95
1078 --------------------
1079
1080 * Fixed bug in mulscc instruction (how could that ever have worked?)
1081
1082 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1083
1084 version 1.2 13-07-95
1085 --------------------
1086
1087 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1088 one interrupt pending)
1089
1090 * Fixed updating of condition codes during logical instructions (carry and
1091 overflow were not reset)
1092
1093 * Fixed bug in WRTBR (tt field was wrongly over-written)
1094
1095 version 1.1 07-07-95
1096 --------------------
1097
1098 * Fixed several bugs in the interrupt handler and callback routines.
1099 (reported by Paul Warren, Alsys)
