 534 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 535
 536         * exec.c (dispatch_instruction):
 537         Correct the sense of the
 538                   if (!sparclite) {
 539                      sregs->trap = TRAP_UNIMP;
 540                      break;
 541                   }
 542         clause that has been pasted around: it's correct in the SCAN and
 543         DIVScc (divide step) cases (where it was probably originally
 544         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 545         ie. instructions only in the SPARC V8 or SPARClite 86x
 546         architectures.  It was also present when not required for SMUL,
 547         SMULcc, UMUL, UMULcc instructions that are present in all
 548         architectures.
 549
 550 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 551
 552         * interf.c (run_sim): Fix a bug in the main loop's handling of
 553         annulled delay slot instructions.  There is precedent for this
 554         change; the _other_ main loop in sis.c gets it right according to
 555         my reading of the code.
 556
 557         The bug is: if an interrupt happens when the next instruction
 558         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 559         with the current values of PC and NPC, so when the trap returns,
 560         the annulled instruction is indeed executed.  Another giveaway is
 561         that the annul flag is cleared in execute_trap(): the information
 562         is demonstrably discarded.
 563
 564         The solution is: perform annulling before looking for traps, in
 565         fact it's neater to do annulling, see if there's an interrupt and
 566         if not, do the instruction, then handle traps be they generated by
 567         interrupts pending or by the instruction we might just have done.
 568         That's what the sis.c one does.
 569
 570 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 571
 572         * sis.h: Add asr17 register for support of SparcLITE (at least the
 573         Hitachi ones I find before me)
 574
 575         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 576         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 577         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 578         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 579         (init_regs): Initialize y and asr17.
 580         NB: In instruction-set space, the Y register is asr0; the
 581         instructions have different names for human reasons only.
 582
 583         * sis.c:
 584         * interf.c: Set boolean mode variable dumbio if invoked with
 585         argument "-dumbio" and mention it of verbose.
 586         * erc32.c: if "dumbio" is set, do not assume that there is a
 587         terminal type device attached to stdin/stdout.  Do not set
 588         buffering or mess with tcsetattr or do any read operations in
 589         order to make UART interrupts; not input data is supported.
 590         This is necessary to allow the sim to be used within the eCos
 591         testing infrastructure where stdin/stdout are pipes to a TCL
 592         program; the sim hangs otherwise.
 593
 594 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>

 615         byte-swapping unnecessary.  Add -sparclite-board option for
 616         emulating RAM found on typical SPARClite boards.  Print
 617         error message for unrecognized option.
 618         * erc32.c: Change RAM address and size from constants to variables,
 619         to allow emulation of SPARClite board RAM.

 625         (get_mem_ptr): Remove unnecessary byte parameter.
 626         (sis_memory_write, sis_memory_read): Store words in target

 999         byte.
1000
1001 Version 2.1 26-02-96
1002 --------------------
1003
1004 * Fixed bug in "go" command.
1005
1006 version 2.0 05-02-96
1007 --------------------
1008
1009 * Fixed bug in interrupt force register (erc32.c).
1010
1011 * Change file load function to use bfd_openr.
1012
1013 * SIS should now be endian independent.
1014
1015 version 1.8 24-11-95
1016 --------------------
1017
1018 * Fixed FPU timing - some sequences of FPU instructions did not calculate
1019   the resource dependencies right.
1020
1021 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
1022   but no FPU trap is generated.
1023
1024 version 1.7.1 31-10-95
1025 --------------------
1026
1027 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1028   the FPU stays in execute mode.
1029
1030 * Corrected JMPL and RETT timing (these instructions takes two cycles).
1031
1032
1033 version 1.7 25-10-95
1034 --------------------
1035
1036 * Interrupt during annuled instruction corrupted return address - fixed.
1037
1038
1039 version 1.6.2 25-10-95
1040 --------------------
1041
1042 * Added -DFAST_UART to Makefile
1043
1044
1045 version 1.6.1 24-10-95
1046 --------------------
1047
1048 * Fixed bug in STDFQ which caused bus error
1049
1050
1051 version 1.6 02-10-95
1052 --------------------
1053
1054 * Modified srt0.s to include code that initiates registers in IU and FPU
1055   and initializes the data segment. The simulator 'load' command does not
1056   longer initialize the data segment!
1057
1058 * Corrected MEC timer operation; scalers now divide the frequency by
1059   (scaler_value + 1).
1060
1061 * MEC breakpoints are not checked during store operation
1062
1063
1064 version 1.5 14-09-95
1065 --------------------
1066
1067 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1068
1069 * Fixed bug that allowed an annuled instruction to cause memory exception.
1070
1071 * The *ws parameter in mem.c should now contain the number of waitstates
1072   required by the memory access (was total number of cycles).
1073
1074 * The supplied srt0.s now clears the BSS (thanks Joel).
1075
1076 version 1.4 22-08-95
1077 --------------------
1078
1079 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1080 some problems on solaris 2.x machines.
1081
1082 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1083 may suffer a bit ...
1084
1085 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1086
1087 version 1.3 26-07-95
1088 --------------------
1089
1090 * Fixed bug in mulscc instruction (how could that ever have worked?)
1091
1092 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1093
1094 version 1.2 13-07-95
1095 --------------------
1096
1097 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1098 one interrupt pending)
1099
1100 * Fixed updating of condition codes during logical instructions (carry and
1101 overflow were not reset)
1102
1103 * Fixed bug in WRTBR (tt field was wrongly over-written)
1104
1105 version 1.1 07-07-95
1106 --------------------
1107
1108 * Fixed several bugs in the interrupt handler and callback routines.
1109 (reported by Paul Warren, Alsys)
