 466 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 467
 468         * exec.c (dispatch_instruction):
 469         Correct the sense of the
 470                   if (!sparclite) {
 471                      sregs->trap = TRAP_UNIMP;
 472                      break;
 473                   }
 474         clause that has been pasted around: it's correct in the SCAN and
 475         DIVScc (divide step) cases (where it was probably originally
 476         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 477         ie. instructions only in the SPARC V8 or SPARClite 86x
 478         architectures.  It was also present when not required for SMUL,
 479         SMULcc, UMUL, UMULcc instructions that are present in all
 480         architectures.
 481
 482 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 483
 484         * interf.c (run_sim): Fix a bug in the main loop's handling of
 485         annulled delay slot instructions.  There is precedent for this
 486         change; the _other_ main loop in sis.c gets it right according to
 487         my reading of the code.
 488
 489         The bug is: if an interrupt happens when the next instruction
 490         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 491         with the current values of PC and NPC, so when the trap returns,
 492         the annulled instruction is indeed executed.  Another giveaway is
 493         that the annul flag is cleared in execute_trap(): the information
 494         is demonstrably discarded.
 495
 496         The solution is: perform annulling before looking for traps, in
 497         fact it's neater to do annulling, see if there's an interrupt and
 498         if not, do the instruction, then handle traps be they generated by
 499         interrupts pending or by the instruction we might just have done.
 500         That's what the sis.c one does.
 501
 502 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 503
 504         * sis.h: Add asr17 register for support of SparcLITE (at least the
 505         Hitachi ones I find before me)
 506
 507         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 508         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 509         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 510         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 511         (init_regs): Initialize y and asr17.
 512         NB: In instruction-set space, the Y register is asr0; the
 513         instructions have different names for human reasons only.
 514
 515         * sis.c:
 516         * interf.c: Set boolean mode variable dumbio if invoked with
 517         argument "-dumbio" and mention it of verbose.
 518         * erc32.c: if "dumbio" is set, do not assume that there is a
 519         terminal type device attached to stdin/stdout.  Do not set
 520         buffering or mess with tcsetattr or do any read operations in
 521         order to make UART interrupts; not input data is supported.
 522         This is necessary to allow the sim to be used within the eCos
 523         testing infrastructure where stdin/stdout are pipes to a TCL
 524         program; the sim hangs otherwise.
 525
 526 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>

 547         byte-swapping unnecessary.  Add -sparclite-board option for
 548         emulating RAM found on typical SPARClite boards.  Print
 549         error message for unrecognized option.
 550         * erc32.c: Change RAM address and size from constants to variables,
 551         to allow emulation of SPARClite board RAM.

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

 930         * interf.c(sim_load): Pass the whole string, not just the first
 931         byte.
 932
 933 Version 2.1 26-02-96
 934 --------------------
 935
 936 * Fixed bug in "go" command.
 937
 938 version 2.0 05-02-96
 939 --------------------
 940
 941 * Fixed bug in interrupt force register (erc32.c).
 942
 943 * Change file load function to use bfd_openr.
 944
 945 * SIS should now be endian independent.
 946
 947 version 1.8 24-11-95
 948 --------------------
 949
 950 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 951   the resource dependencies right.
 952
 953 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 954   but no FPU trap is generated.
 955
 956 version 1.7.1 31-10-95
 957 --------------------
 958
 959 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 960   the FPU stays in execute mode.
 961
 962 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 963
 964
 965 version 1.7 25-10-95
 966 --------------------
 967
 968 * Interrupt during annuled instruction corrupted return address - fixed.
 969
 970
 971 version 1.6.2 25-10-95
 972 --------------------
 973
 974 * Added -DFAST_UART to Makefile
 975
 976
 977 version 1.6.1 24-10-95
 978 --------------------
 979
 980 * Fixed bug in STDFQ which caused bus error
 981
 982
 983 version 1.6 02-10-95
 984 --------------------
 985
 986 * Modified srt0.s to include code that initiates registers in IU and FPU
 987   and initializes the data segment. The simulator 'load' command does not
 988   longer initialize the data segment!
 989
 990 * Corrected MEC timer operation; scalers now divide the frequency by
 991   (scaler_value + 1).
 992
 993 * MEC breakpoints are not checked during store operation
 994
 995
 996 version 1.5 14-09-95
 997 --------------------
 998
 999 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1000
1001 * Fixed bug that allowed an annuled instruction to cause memory exception.
1002
1003 * The *ws parameter in mem.c should now contain the number of waitstates
1004   required by the memory access (was total number of cycles).
1005
1006 * The supplied srt0.s now clears the BSS (thanks Joel).
1007
1008 version 1.4 22-08-95
1009 --------------------
1010
1011 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1012 some problems on solaris 2.x machines.
1013
1014 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1015 may suffer a bit ...
1016
1017 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1018
1019 version 1.3 26-07-95
1020 --------------------
1021
1022 * Fixed bug in mulscc instruction (how could that ever have worked?)
1023
1024 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1025
1026 version 1.2 13-07-95
1027 --------------------
1028
1029 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1030 one interrupt pending)
1031
1032 * Fixed updating of condition codes during logical instructions (carry and
1033 overflow were not reset)
1034
1035 * Fixed bug in WRTBR (tt field was wrongly over-written)
1036
1037 version 1.1 07-07-95
1038 --------------------
1039
1040 * Fixed several bugs in the interrupt handler and callback routines.
1041 (reported by Paul Warren, Alsys)
