 458 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 459
 460         * exec.c (dispatch_instruction):
 461         Correct the sense of the
 462                   if (!sparclite) {
 463                      sregs->trap = TRAP_UNIMP;
 464                      break;
 465                   }
 466         clause that has been pasted around: it's correct in the SCAN and
 467         DIVScc (divide step) cases (where it was probably originally
 468         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 469         ie. instructions only in the SPARC V8 or SPARClite 86x
 470         architectures.  It was also present when not required for SMUL,
 471         SMULcc, UMUL, UMULcc instructions that are present in all
 472         architectures.
 473
 474 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 475
 476         * interf.c (run_sim): Fix a bug in the main loop's handling of
 477         annulled delay slot instructions.  There is precedent for this
 478         change; the _other_ main loop in sis.c gets it right according to
 479         my reading of the code.
 480
 481         The bug is: if an interrupt happens when the next instruction
 482         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 483         with the current values of PC and NPC, so when the trap returns,
 484         the annulled instruction is indeed executed.  Another giveaway is
 485         that the annul flag is cleared in execute_trap(): the information
 486         is demonstrably discarded.
 487
 488         The solution is: perform annulling before looking for traps, in
 489         fact it's neater to do annulling, see if there's an interrupt and
 490         if not, do the instruction, then handle traps be they generated by
 491         interrupts pending or by the instruction we might just have done.
 492         That's what the sis.c one does.
 493
 494 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 495
 496         * sis.h: Add asr17 register for support of SparcLITE (at least the
 497         Hitachi ones I find before me)
 498
 499         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 500         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 501         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 502         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 503         (init_regs): Initialize y and asr17.
 504         NB: In instruction-set space, the Y register is asr0; the
 505         instructions have different names for human reasons only.
 506
 507         * sis.c:
 508         * interf.c: Set boolean mode variable dumbio if invoked with
 509         argument "-dumbio" and mention it of verbose.
 510         * erc32.c: if "dumbio" is set, do not assume that there is a
 511         terminal type device attached to stdin/stdout.  Do not set
 512         buffering or mess with tcsetattr or do any read operations in
 513         order to make UART interrupts; not input data is supported.
 514         This is necessary to allow the sim to be used within the eCos
 515         testing infrastructure where stdin/stdout are pipes to a TCL
 516         program; the sim hangs otherwise.
 517
 518 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>

 539         byte-swapping unnecessary.  Add -sparclite-board option for
 540         emulating RAM found on typical SPARClite boards.  Print
 541         error message for unrecognized option.
 542         * erc32.c: Change RAM address and size from constants to variables,
 543         to allow emulation of SPARClite board RAM.

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

 923         byte.
 924
 925 Version 2.1 26-02-96
 926 --------------------
 927
 928 * Fixed bug in "go" command.
 929
 930 version 2.0 05-02-96
 931 --------------------
 932
 933 * Fixed bug in interrupt force register (erc32.c).
 934
 935 * Change file load function to use bfd_openr.
 936
 937 * SIS should now be endian independent.
 938
 939 version 1.8 24-11-95
 940 --------------------
 941
 942 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 943   the resource dependencies right.
 944
 945 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 946   but no FPU trap is generated.
 947
 948 version 1.7.1 31-10-95
 949 --------------------
 950
 951 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 952   the FPU stays in execute mode.
 953
 954 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 955
 956
 957 version 1.7 25-10-95
 958 --------------------
 959
 960 * Interrupt during annuled instruction corrupted return address - fixed.
 961
 962
 963 version 1.6.2 25-10-95
 964 --------------------
 965
 966 * Added -DFAST_UART to Makefile
 967
 968
 969 version 1.6.1 24-10-95
 970 --------------------
 971
 972 * Fixed bug in STDFQ which caused bus error
 973
 974
 975 version 1.6 02-10-95
 976 --------------------
 977
 978 * Modified srt0.s to include code that initiates registers in IU and FPU
 979   and initializes the data segment. The simulator 'load' command does not
 980   longer initialize the data segment!
 981
 982 * Corrected MEC timer operation; scalers now divide the frequency by
 983   (scaler_value + 1).
 984
 985 * MEC breakpoints are not checked during store operation
 986
 987
 988 version 1.5 14-09-95
 989 --------------------
 990
 991 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 992
 993 * Fixed bug that allowed an annuled instruction to cause memory exception.
 994
 995 * The *ws parameter in mem.c should now contain the number of waitstates
 996   required by the memory access (was total number of cycles).
 997
 998 * The supplied srt0.s now clears the BSS (thanks Joel).
 999
1000 version 1.4 22-08-95
1001 --------------------
1002
1003 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1004 some problems on solaris 2.x machines.
1005
1006 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1007 may suffer a bit ...
1008
1009 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1010
1011 version 1.3 26-07-95
1012 --------------------
1013
1014 * Fixed bug in mulscc instruction (how could that ever have worked?)
1015
1016 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1017
1018 version 1.2 13-07-95
1019 --------------------
1020
1021 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1022 one interrupt pending)
1023
1024 * Fixed updating of condition codes during logical instructions (carry and
1025 overflow were not reset)
1026
1027 * Fixed bug in WRTBR (tt field was wrongly over-written)
1028
1029 version 1.1 07-07-95
1030 --------------------
1031
1032 * Fixed several bugs in the interrupt handler and callback routines.
1033 (reported by Paul Warren, Alsys)
