 500 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 501
 502         * exec.c (dispatch_instruction):
 503         Correct the sense of the
 504                   if (!sparclite) {
 505                      sregs->trap = TRAP_UNIMP;
 506                      break;
 507                   }
 508         clause that has been pasted around: it's correct in the SCAN and
 509         DIVScc (divide step) cases (where it was probably originally
 510         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 511         ie. instructions only in the SPARC V8 or SPARClite 86x
 512         architectures.  It was also present when not required for SMUL,
 513         SMULcc, UMUL, UMULcc instructions that are present in all
 514         architectures.
 515
 516 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 517
 518         * interf.c (run_sim): Fix a bug in the main loop's handling of
 519         annulled delay slot instructions.  There is precedent for this
 520         change; the _other_ main loop in sis.c gets it right according to
 521         my reading of the code.
 522
 523         The bug is: if an interrupt happens when the next instruction
 524         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 525         with the current values of PC and NPC, so when the trap returns,
 526         the annulled instruction is indeed executed.  Another giveaway is
 527         that the annul flag is cleared in execute_trap(): the information
 528         is demonstrably discarded.
 529
 530         The solution is: perform annulling before looking for traps, in
 531         fact it's neater to do annulling, see if there's an interrupt and
 532         if not, do the instruction, then handle traps be they generated by
 533         interrupts pending or by the instruction we might just have done.
 534         That's what the sis.c one does.
 535
 536 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 537
 538         * sis.h: Add asr17 register for support of SparcLITE (at least the
 539         Hitachi ones I find before me)
 540
 541         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 542         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 543         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 544         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 545         (init_regs): Initialize y and asr17.
 546         NB: In instruction-set space, the Y register is asr0; the
 547         instructions have different names for human reasons only.
 548
 549         * sis.c:
 550         * interf.c: Set boolean mode variable dumbio if invoked with
 551         argument "-dumbio" and mention it of verbose.
 552         * erc32.c: if "dumbio" is set, do not assume that there is a
 553         terminal type device attached to stdin/stdout.  Do not set
 554         buffering or mess with tcsetattr or do any read operations in
 555         order to make UART interrupts; not input data is supported.
 556         This is necessary to allow the sim to be used within the eCos
 557         testing infrastructure where stdin/stdout are pipes to a TCL
 558         program; the sim hangs otherwise.
 559
 560 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>

 581         byte-swapping unnecessary.  Add -sparclite-board option for
 582         emulating RAM found on typical SPARClite boards.  Print
 583         error message for unrecognized option.
 584         * erc32.c: Change RAM address and size from constants to variables,
 585         to allow emulation of SPARClite board RAM.

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

 966
 967 Version 2.1 26-02-96
 968 --------------------
 969
 970 * Fixed bug in "go" command.
 971
 972 version 2.0 05-02-96
 973 --------------------
 974
 975 * Fixed bug in interrupt force register (erc32.c).
 976
 977 * Change file load function to use bfd_openr.
 978
 979 * SIS should now be endian independent.
 980
 981 version 1.8 24-11-95
 982 --------------------
 983
 984 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 985   the resource dependencies right.
 986
 987 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 988   but no FPU trap is generated.
 989
 990 version 1.7.1 31-10-95
 991 --------------------
 992
 993 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 994   the FPU stays in execute mode.
 995
 996 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 997
 998
 999 version 1.7 25-10-95
1000 --------------------
1001
1002 * Interrupt during annuled instruction corrupted return address - fixed.
1003
1004
1005 version 1.6.2 25-10-95
1006 --------------------
1007
1008 * Added -DFAST_UART to Makefile
1009
1010
1011 version 1.6.1 24-10-95
1012 --------------------
1013
1014 * Fixed bug in STDFQ which caused bus error
1015
1016
1017 version 1.6 02-10-95
1018 --------------------
1019
1020 * Modified srt0.s to include code that initiates registers in IU and FPU
1021   and initializes the data segment. The simulator 'load' command does not
1022   longer initialize the data segment!
1023
1024 * Corrected MEC timer operation; scalers now divide the frequency by
1025   (scaler_value + 1).
1026
1027 * MEC breakpoints are not checked during store operation
1028
1029
1030 version 1.5 14-09-95
1031 --------------------
1032
1033 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1034
1035 * Fixed bug that allowed an annuled instruction to cause memory exception.
1036
1037 * The *ws parameter in mem.c should now contain the number of waitstates
1038   required by the memory access (was total number of cycles).
1039
1040 * The supplied srt0.s now clears the BSS (thanks Joel).
1041
1042 version 1.4 22-08-95
1043 --------------------
1044
1045 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1046 some problems on solaris 2.x machines.
1047
1048 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1049 may suffer a bit ...
1050
1051 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1052
1053 version 1.3 26-07-95
1054 --------------------
1055
1056 * Fixed bug in mulscc instruction (how could that ever have worked?)
1057
1058 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1059
1060 version 1.2 13-07-95
1061 --------------------
1062
1063 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1064 one interrupt pending)
1065
1066 * Fixed updating of condition codes during logical instructions (carry and
1067 overflow were not reset)
1068
1069 * Fixed bug in WRTBR (tt field was wrongly over-written)
1070
1071 version 1.1 07-07-95
1072 --------------------
1073
1074 * Fixed several bugs in the interrupt handler and callback routines.
1075 (reported by Paul Warren, Alsys)
