 479 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 480
 481         * exec.c (dispatch_instruction):
 482         Correct the sense of the
 483                   if (!sparclite) {
 484                      sregs->trap = TRAP_UNIMP;
 485                      break;
 486                   }
 487         clause that has been pasted around: it's correct in the SCAN and
 488         DIVScc (divide step) cases (where it was probably originally
 489         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 490         ie. instructions only in the SPARC V8 or SPARClite 86x
 491         architectures.  It was also present when not required for SMUL,
 492         SMULcc, UMUL, UMULcc instructions that are present in all
 493         architectures.
 494
 495 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 496
 497         * interf.c (run_sim): Fix a bug in the main loop's handling of
 498         annulled delay slot instructions.  There is precedent for this
 499         change; the _other_ main loop in sis.c gets it right according to
 500         my reading of the code.
 501
 502         The bug is: if an interrupt happens when the next instruction
 503         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 504         with the current values of PC and NPC, so when the trap returns,
 505         the annulled instruction is indeed executed.  Another giveaway is
 506         that the annul flag is cleared in execute_trap(): the information
 507         is demonstrably discarded.
 508
 509         The solution is: perform annulling before looking for traps, in
 510         fact it's neater to do annulling, see if there's an interrupt and
 511         if not, do the instruction, then handle traps be they generated by
 512         interrupts pending or by the instruction we might just have done.
 513         That's what the sis.c one does.
 514
 515 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 516
 517         * sis.h: Add asr17 register for support of SparcLITE (at least the
 518         Hitachi ones I find before me)
 519
 520         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 521         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 522         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 523         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 524         (init_regs): Initialize y and asr17.
 525         NB: In instruction-set space, the Y register is asr0; the
 526         instructions have different names for human reasons only.
 527
 528         * sis.c:
 529         * interf.c: Set boolean mode variable dumbio if invoked with
 530         argument "-dumbio" and mention it of verbose.
 531         * erc32.c: if "dumbio" is set, do not assume that there is a
 532         terminal type device attached to stdin/stdout.  Do not set
 533         buffering or mess with tcsetattr or do any read operations in
 534         order to make UART interrupts; not input data is supported.
 535         This is necessary to allow the sim to be used within the eCos
 536         testing infrastructure where stdin/stdout are pipes to a TCL
 537         program; the sim hangs otherwise.
 538
 539 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>

 560         byte-swapping unnecessary.  Add -sparclite-board option for
 561         emulating RAM found on typical SPARClite boards.  Print
 562         error message for unrecognized option.
 563         * erc32.c: Change RAM address and size from constants to variables,
 564         to allow emulation of SPARClite board RAM.

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

 944         byte.
 945
 946 Version 2.1 26-02-96
 947 --------------------
 948
 949 * Fixed bug in "go" command.
 950
 951 version 2.0 05-02-96
 952 --------------------
 953
 954 * Fixed bug in interrupt force register (erc32.c).
 955
 956 * Change file load function to use bfd_openr.
 957
 958 * SIS should now be endian independent.
 959
 960 version 1.8 24-11-95
 961 --------------------
 962
 963 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 964   the resource dependencies right.
 965
 966 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 967   but no FPU trap is generated.
 968
 969 version 1.7.1 31-10-95
 970 --------------------
 971
 972 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 973   the FPU stays in execute mode.
 974
 975 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 976
 977
 978 version 1.7 25-10-95
 979 --------------------
 980
 981 * Interrupt during annuled instruction corrupted return address - fixed.
 982
 983
 984 version 1.6.2 25-10-95
 985 --------------------
 986
 987 * Added -DFAST_UART to Makefile
 988
 989
 990 version 1.6.1 24-10-95
 991 --------------------
 992
 993 * Fixed bug in STDFQ which caused bus error
 994
 995
 996 version 1.6 02-10-95
 997 --------------------
 998
 999 * Modified srt0.s to include code that initiates registers in IU and FPU
1000   and initializes the data segment. The simulator 'load' command does not
1001   longer initialize the data segment!
1002
1003 * Corrected MEC timer operation; scalers now divide the frequency by
1004   (scaler_value + 1).
1005
1006 * MEC breakpoints are not checked during store operation
1007
1008
1009 version 1.5 14-09-95
1010 --------------------
1011
1012 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1013
1014 * Fixed bug that allowed an annuled instruction to cause memory exception.
1015
1016 * The *ws parameter in mem.c should now contain the number of waitstates
1017   required by the memory access (was total number of cycles).
1018
1019 * The supplied srt0.s now clears the BSS (thanks Joel).
1020
1021 version 1.4 22-08-95
1022 --------------------
1023
1024 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1025 some problems on solaris 2.x machines.
1026
1027 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1028 may suffer a bit ...
1029
1030 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1031
1032 version 1.3 26-07-95
1033 --------------------
1034
1035 * Fixed bug in mulscc instruction (how could that ever have worked?)
1036
1037 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1038
1039 version 1.2 13-07-95
1040 --------------------
1041
1042 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1043 one interrupt pending)
1044
1045 * Fixed updating of condition codes during logical instructions (carry and
1046 overflow were not reset)
1047
1048 * Fixed bug in WRTBR (tt field was wrongly over-written)
1049
1050 version 1.1 07-07-95
1051 --------------------
1052
1053 * Fixed several bugs in the interrupt handler and callback routines.
1054 (reported by Paul Warren, Alsys)
