 516 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 517
 518         * exec.c (dispatch_instruction):
 519         Correct the sense of the
 520                   if (!sparclite) {
 521                      sregs->trap = TRAP_UNIMP;
 522                      break;
 523                   }
 524         clause that has been pasted around: it's correct in the SCAN and
 525         DIVScc (divide step) cases (where it was probably originally
 526         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 527         ie. instructions only in the SPARC V8 or SPARClite 86x
 528         architectures.  It was also present when not required for SMUL,
 529         SMULcc, UMUL, UMULcc instructions that are present in all
 530         architectures.
 531
 532 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 533
 534         * interf.c (run_sim): Fix a bug in the main loop's handling of
 535         annulled delay slot instructions.  There is precedent for this
 536         change; the _other_ main loop in sis.c gets it right according to
 537         my reading of the code.
 538
 539         The bug is: if an interrupt happens when the next instruction
 540         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 541         with the current values of PC and NPC, so when the trap returns,
 542         the annulled instruction is indeed executed.  Another giveaway is
 543         that the annul flag is cleared in execute_trap(): the information
 544         is demonstrably discarded.
 545
 546         The solution is: perform annulling before looking for traps, in
 547         fact it's neater to do annulling, see if there's an interrupt and
 548         if not, do the instruction, then handle traps be they generated by
 549         interrupts pending or by the instruction we might just have done.
 550         That's what the sis.c one does.
 551
 552 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 553
 554         * sis.h: Add asr17 register for support of SparcLITE (at least the
 555         Hitachi ones I find before me)
 556
 557         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 558         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 559         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 560         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 561         (init_regs): Initialize y and asr17.
 562         NB: In instruction-set space, the Y register is asr0; the
 563         instructions have different names for human reasons only.
 564
 565         * sis.c:
 566         * interf.c: Set boolean mode variable dumbio if invoked with
 567         argument "-dumbio" and mention it of verbose.
 568         * erc32.c: if "dumbio" is set, do not assume that there is a
 569         terminal type device attached to stdin/stdout.  Do not set
 570         buffering or mess with tcsetattr or do any read operations in
 571         order to make UART interrupts; not input data is supported.
 572         This is necessary to allow the sim to be used within the eCos
 573         testing infrastructure where stdin/stdout are pipes to a TCL
 574         program; the sim hangs otherwise.

 597         byte-swapping unnecessary.  Add -sparclite-board option for
 598         emulating RAM found on typical SPARClite boards.  Print
 599         error message for unrecognized option.

 607         (get_mem_ptr): Remove unnecessary byte parameter.

 981         byte.
 982
 983 Version 2.1 26-02-96
 984 --------------------
 985
 986 * Fixed bug in "go" command.
 987
 988 version 2.0 05-02-96
 989 --------------------
 990
 991 * Fixed bug in interrupt force register (erc32.c).
 992
 993 * Change file load function to use bfd_openr.
 994
 995 * SIS should now be endian independent.
 996
 997 version 1.8 24-11-95
 998 --------------------
 999
1000 * Fixed FPU timing - some sequences of FPU instructions did not calculate
1001   the resource dependencies right.
1002
1003 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
1004   but no FPU trap is generated.
1005
1006 version 1.7.1 31-10-95
1007 --------------------
1008
1009 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1010   the FPU stays in execute mode.
1011
1012 * Corrected JMPL and RETT timing (these instructions takes two cycles).
1013
1014
1015 version 1.7 25-10-95
1016 --------------------
1017
1018 * Interrupt during annuled instruction corrupted return address - fixed.
1019
1020
1021 version 1.6.2 25-10-95
1022 --------------------
1023
1024 * Added -DFAST_UART to Makefile
1025
1026
1027 version 1.6.1 24-10-95
1028 --------------------
1029
1030 * Fixed bug in STDFQ which caused bus error
1031
1032
1033 version 1.6 02-10-95
1034 --------------------
1035
1036 * Modified srt0.s to include code that initiates registers in IU and FPU
1037   and initializes the data segment. The simulator 'load' command does not
1038   longer initialize the data segment!
1039
1040 * Corrected MEC timer operation; scalers now divide the frequency by
1041   (scaler_value + 1).
1042
1043 * MEC breakpoints are not checked during store operation
1044
1045
1046 version 1.5 14-09-95
1047 --------------------
1048
1049 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1050
1051 * Fixed bug that allowed an annuled instruction to cause memory exception.
1052
1053 * The *ws parameter in mem.c should now contain the number of waitstates
1054   required by the memory access (was total number of cycles).
1055
1056 * The supplied srt0.s now clears the BSS (thanks Joel).
1057
1058 version 1.4 22-08-95
1059 --------------------
1060
1061 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1062 some problems on solaris 2.x machines.
1063
1064 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1065 may suffer a bit ...
1066
1067 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1068
1069 version 1.3 26-07-95
1070 --------------------
1071
1072 * Fixed bug in mulscc instruction (how could that ever have worked?)
1073
1074 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1075
1076 version 1.2 13-07-95
1077 --------------------
1078
1079 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1080 one interrupt pending)
1081
1082 * Fixed updating of condition codes during logical instructions (carry and
1083 overflow were not reset)
1084
1085 * Fixed bug in WRTBR (tt field was wrongly over-written)
1086
1087 version 1.1 07-07-95
1088 --------------------
1089
1090 * Fixed several bugs in the interrupt handler and callback routines.
1091 (reported by Paul Warren, Alsys)
