 504 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 505
 506         * exec.c (dispatch_instruction):
 507         Correct the sense of the
 508                   if (!sparclite) {
 509                      sregs->trap = TRAP_UNIMP;
 510                      break;
 511                   }
 512         clause that has been pasted around: it's correct in the SCAN and
 513         DIVScc (divide step) cases (where it was probably originally
 514         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 515         ie. instructions only in the SPARC V8 or SPARClite 86x
 516         architectures.  It was also present when not required for SMUL,
 517         SMULcc, UMUL, UMULcc instructions that are present in all
 518         architectures.
 519
 520 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 521
 522         * interf.c (run_sim): Fix a bug in the main loop's handling of
 523         annulled delay slot instructions.  There is precedent for this
 524         change; the _other_ main loop in sis.c gets it right according to
 525         my reading of the code.
 526
 527         The bug is: if an interrupt happens when the next instruction
 528         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 529         with the current values of PC and NPC, so when the trap returns,
 530         the annulled instruction is indeed executed.  Another giveaway is
 531         that the annul flag is cleared in execute_trap(): the information
 532         is demonstrably discarded.
 533
 534         The solution is: perform annulling before looking for traps, in
 535         fact it's neater to do annulling, see if there's an interrupt and
 536         if not, do the instruction, then handle traps be they generated by
 537         interrupts pending or by the instruction we might just have done.
 538         That's what the sis.c one does.
 539
 540 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 541
 542         * sis.h: Add asr17 register for support of SparcLITE (at least the
 543         Hitachi ones I find before me)
 544
 545         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 546         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 547         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 548         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 549         (init_regs): Initialize y and asr17.
 550         NB: In instruction-set space, the Y register is asr0; the
 551         instructions have different names for human reasons only.
 552
 553         * sis.c:
 554         * interf.c: Set boolean mode variable dumbio if invoked with
 555         argument "-dumbio" and mention it of verbose.
 556         * erc32.c: if "dumbio" is set, do not assume that there is a
 557         terminal type device attached to stdin/stdout.  Do not set
 558         buffering or mess with tcsetattr or do any read operations in
 559         order to make UART interrupts; not input data is supported.
 560         This is necessary to allow the sim to be used within the eCos
 561         testing infrastructure where stdin/stdout are pipes to a TCL
 562         program; the sim hangs otherwise.
 563
 564 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>

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

 592         (memory_read, memory_write): Rewrite to store bytes in target

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

 970
 971 Version 2.1 26-02-96
 972 --------------------
 973
 974 * Fixed bug in "go" command.
 975
 976 version 2.0 05-02-96
 977 --------------------
 978
 979 * Fixed bug in interrupt force register (erc32.c).
 980
 981 * Change file load function to use bfd_openr.
 982
 983 * SIS should now be endian independent.
 984
 985 version 1.8 24-11-95
 986 --------------------
 987
 988 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 989   the resource dependencies right.
 990
 991 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 992   but no FPU trap is generated.
 993
 994 version 1.7.1 31-10-95
 995 --------------------
 996
 997 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 998   the FPU stays in execute mode.
 999
1000 * Corrected JMPL and RETT timing (these instructions takes two cycles).
1001
1002
1003 version 1.7 25-10-95
1004 --------------------
1005
1006 * Interrupt during annuled instruction corrupted return address - fixed.
1007
1008
1009 version 1.6.2 25-10-95
1010 --------------------
1011
1012 * Added -DFAST_UART to Makefile
1013
1014
1015 version 1.6.1 24-10-95
1016 --------------------
1017
1018 * Fixed bug in STDFQ which caused bus error
1019
1020
1021 version 1.6 02-10-95
1022 --------------------
1023
1024 * Modified srt0.s to include code that initiates registers in IU and FPU
1025   and initializes the data segment. The simulator 'load' command does not
1026   longer initialize the data segment!
1027
1028 * Corrected MEC timer operation; scalers now divide the frequency by
1029   (scaler_value + 1).
1030
1031 * MEC breakpoints are not checked during store operation
1032
1033
1034 version 1.5 14-09-95
1035 --------------------
1036
1037 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1038
1039 * Fixed bug that allowed an annuled instruction to cause memory exception.
1040
1041 * The *ws parameter in mem.c should now contain the number of waitstates
1042   required by the memory access (was total number of cycles).
1043
1044 * The supplied srt0.s now clears the BSS (thanks Joel).
1045
1046 version 1.4 22-08-95
1047 --------------------
1048
1049 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1050 some problems on solaris 2.x machines.
1051
1052 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1053 may suffer a bit ...
1054
1055 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1056
1057 version 1.3 26-07-95
1058 --------------------
1059
1060 * Fixed bug in mulscc instruction (how could that ever have worked?)
1061
1062 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1063
1064 version 1.2 13-07-95
1065 --------------------
1066
1067 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1068 one interrupt pending)
1069
1070 * Fixed updating of condition codes during logical instructions (carry and
1071 overflow were not reset)
1072
1073 * Fixed bug in WRTBR (tt field was wrongly over-written)
1074
1075 version 1.1 07-07-95
1076 --------------------
1077
1078 * Fixed several bugs in the interrupt handler and callback routines.
1079 (reported by Paul Warren, Alsys)
