 508 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 509
 510         * exec.c (dispatch_instruction):
 511         Correct the sense of the
 512                   if (!sparclite) {
 513                      sregs->trap = TRAP_UNIMP;
 514                      break;
 515                   }
 516         clause that has been pasted around: it's correct in the SCAN and
 517         DIVScc (divide step) cases (where it was probably originally
 518         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 519         ie. instructions only in the SPARC V8 or SPARClite 86x
 520         architectures.  It was also present when not required for SMUL,
 521         SMULcc, UMUL, UMULcc instructions that are present in all
 522         architectures.
 523
 524 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 525
 526         * interf.c (run_sim): Fix a bug in the main loop's handling of
 527         annulled delay slot instructions.  There is precedent for this
 528         change; the _other_ main loop in sis.c gets it right according to
 529         my reading of the code.
 530
 531         The bug is: if an interrupt happens when the next instruction
 532         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 533         with the current values of PC and NPC, so when the trap returns,
 534         the annulled instruction is indeed executed.  Another giveaway is
 535         that the annul flag is cleared in execute_trap(): the information
 536         is demonstrably discarded.
 537
 538         The solution is: perform annulling before looking for traps, in
 539         fact it's neater to do annulling, see if there's an interrupt and
 540         if not, do the instruction, then handle traps be they generated by
 541         interrupts pending or by the instruction we might just have done.
 542         That's what the sis.c one does.
 543
 544 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 545
 546         * sis.h: Add asr17 register for support of SparcLITE (at least the
 547         Hitachi ones I find before me)
 548
 549         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 550         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 551         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 552         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 553         (init_regs): Initialize y and asr17.
 554         NB: In instruction-set space, the Y register is asr0; the
 555         instructions have different names for human reasons only.
 556
 557         * sis.c:
 558         * interf.c: Set boolean mode variable dumbio if invoked with
 559         argument "-dumbio" and mention it of verbose.
 560         * erc32.c: if "dumbio" is set, do not assume that there is a
 561         terminal type device attached to stdin/stdout.  Do not set
 562         buffering or mess with tcsetattr or do any read operations in
 563         order to make UART interrupts; not input data is supported.
 564         This is necessary to allow the sim to be used within the eCos
 565         testing infrastructure where stdin/stdout are pipes to a TCL
 566         program; the sim hangs otherwise.
 567
 568 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>

 589         byte-swapping unnecessary.  Add -sparclite-board option for
 590         emulating RAM found on typical SPARClite boards.  Print
 591         error message for unrecognized option.
 592         * erc32.c: Change RAM address and size from constants to variables,
 593         to allow emulation of SPARClite board RAM.

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

 973         byte.
 974
 975 Version 2.1 26-02-96
 976 --------------------
 977
 978 * Fixed bug in "go" command.
 979
 980 version 2.0 05-02-96
 981 --------------------
 982
 983 * Fixed bug in interrupt force register (erc32.c).
 984
 985 * Change file load function to use bfd_openr.
 986
 987 * SIS should now be endian independent.
 988
 989 version 1.8 24-11-95
 990 --------------------
 991
 992 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 993   the resource dependencies right.
 994
 995 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 996   but no FPU trap is generated.
 997
 998 version 1.7.1 31-10-95
 999 --------------------
1000
1001 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1002   the FPU stays in execute mode.
1003
1004 * Corrected JMPL and RETT timing (these instructions takes two cycles).
1005
1006
1007 version 1.7 25-10-95
1008 --------------------
1009
1010 * Interrupt during annuled instruction corrupted return address - fixed.
1011
1012
1013 version 1.6.2 25-10-95
1014 --------------------
1015
1016 * Added -DFAST_UART to Makefile
1017
1018
1019 version 1.6.1 24-10-95
1020 --------------------
1021
1022 * Fixed bug in STDFQ which caused bus error
1023
1024
1025 version 1.6 02-10-95
1026 --------------------
1027
1028 * Modified srt0.s to include code that initiates registers in IU and FPU
1029   and initializes the data segment. The simulator 'load' command does not
1030   longer initialize the data segment!
1031
1032 * Corrected MEC timer operation; scalers now divide the frequency by
1033   (scaler_value + 1).
1034
1035 * MEC breakpoints are not checked during store operation
1036
1037
1038 version 1.5 14-09-95
1039 --------------------
1040
1041 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1042
1043 * Fixed bug that allowed an annuled instruction to cause memory exception.
1044
1045 * The *ws parameter in mem.c should now contain the number of waitstates
1046   required by the memory access (was total number of cycles).
1047
1048 * The supplied srt0.s now clears the BSS (thanks Joel).
1049
1050 version 1.4 22-08-95
1051 --------------------
1052
1053 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1054 some problems on solaris 2.x machines.
1055
1056 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1057 may suffer a bit ...
1058
1059 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1060
1061 version 1.3 26-07-95
1062 --------------------
1063
1064 * Fixed bug in mulscc instruction (how could that ever have worked?)
1065
1066 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1067
1068 version 1.2 13-07-95
1069 --------------------
1070
1071 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1072 one interrupt pending)
1073
1074 * Fixed updating of condition codes during logical instructions (carry and
1075 overflow were not reset)
1076
1077 * Fixed bug in WRTBR (tt field was wrongly over-written)
1078
1079 version 1.1 07-07-95
1080 --------------------
1081
1082 * Fixed several bugs in the interrupt handler and callback routines.
1083 (reported by Paul Warren, Alsys)
