 434 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 435
 436         * exec.c (dispatch_instruction):
 437         Correct the sense of the
 438                   if (!sparclite) {
 439                      sregs->trap = TRAP_UNIMP;
 440                      break;
 441                   }
 442         clause that has been pasted around: it's correct in the SCAN and
 443         DIVScc (divide step) cases (where it was probably originally
 444         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 445         ie. instructions only in the SPARC V8 or SPARClite 86x
 446         architectures.  It was also present when not required for SMUL,
 447         SMULcc, UMUL, UMULcc instructions that are present in all
 448         architectures.
 449
 450 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 451
 452         * interf.c (run_sim): Fix a bug in the main loop's handling of
 453         annulled delay slot instructions.  There is precedent for this
 454         change; the _other_ main loop in sis.c gets it right according to
 455         my reading of the code.
 456
 457         The bug is: if an interrupt happens when the next instruction
 458         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 459         with the current values of PC and NPC, so when the trap returns,
 460         the annulled instruction is indeed executed.  Another giveaway is
 461         that the annul flag is cleared in execute_trap(): the information
 462         is demonstrably discarded.
 463
 464         The solution is: perform annulling before looking for traps, in
 465         fact it's neater to do annulling, see if there's an interrupt and
 466         if not, do the instruction, then handle traps be they generated by
 467         interrupts pending or by the instruction we might just have done.
 468         That's what the sis.c one does.
 469
 470 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 471
 472         * sis.h: Add asr17 register for support of SparcLITE (at least the
 473         Hitachi ones I find before me)
 474
 475         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 476         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 477         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 478         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 479         (init_regs): Initialize y and asr17.
 480         NB: In instruction-set space, the Y register is asr0; the
 481         instructions have different names for human reasons only.
 482
 483         * sis.c:
 484         * interf.c: Set boolean mode variable dumbio if invoked with
 485         argument "-dumbio" and mention it of verbose.
 486         * erc32.c: if "dumbio" is set, do not assume that there is a
 487         terminal type device attached to stdin/stdout.  Do not set
 488         buffering or mess with tcsetattr or do any read operations in
 489         order to make UART interrupts; not input data is supported.
 490         This is necessary to allow the sim to be used within the eCos
 491         testing infrastructure where stdin/stdout are pipes to a TCL
 492         program; the sim hangs otherwise.

 515         byte-swapping unnecessary.  Add -sparclite-board option for
 516         emulating RAM found on typical SPARClite boards.  Print
 517         error message for unrecognized option.
 518         * erc32.c: Change RAM address and size from constants to variables,

 846

 899         byte.
 900
 901 Version 2.1 26-02-96
 902 --------------------
 903
 904 * Fixed bug in "go" command.
 905
 906 version 2.0 05-02-96
 907 --------------------
 908
 909 * Fixed bug in interrupt force register (erc32.c).
 910
 911 * Change file load function to use bfd_openr.
 912
 913 * SIS should now be endian independent.
 914
 915 version 1.8 24-11-95
 916 --------------------
 917
 918 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 919   the resource dependencies right.
 920
 921 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 922   but no FPU trap is generated.
 923
 924 version 1.7.1 31-10-95
 925 --------------------
 926
 927 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 928   the FPU stays in execute mode.
 929
 930 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 931
 932
 933 version 1.7 25-10-95
 934 --------------------
 935
 936 * Interrupt during annuled instruction corrupted return address - fixed.
 937
 938
 939 version 1.6.2 25-10-95
 940 --------------------
 941
 942 * Added -DFAST_UART to Makefile
 943
 944
 945 version 1.6.1 24-10-95
 946 --------------------
 947
 948 * Fixed bug in STDFQ which caused bus error
 949
 950
 951 version 1.6 02-10-95
 952 --------------------
 953
 954 * Modified srt0.s to include code that initiates registers in IU and FPU
 955   and initializes the data segment. The simulator 'load' command does not
 956   longer initialize the data segment!
 957
 958 * Corrected MEC timer operation; scalers now divide the frequency by
 959   (scaler_value + 1).
 960
 961 * MEC breakpoints are not checked during store operation
 962
 963
 964 version 1.5 14-09-95
 965 --------------------
 966
 967 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 968
 969 * Fixed bug that allowed an annuled instruction to cause memory exception.
 970
 971 * The *ws parameter in mem.c should now contain the number of waitstates
 972   required by the memory access (was total number of cycles).
 973
 974 * The supplied srt0.s now clears the BSS (thanks Joel).
 975
 976 version 1.4 22-08-95
 977 --------------------
 978
 979 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 980 some problems on solaris 2.x machines.
 981
 982 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 983 may suffer a bit ...
 984
 985 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 986
 987 version 1.3 26-07-95
 988 --------------------
 989
 990 * Fixed bug in mulscc instruction (how could that ever have worked?)
 991
 992 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 993
 994 version 1.2 13-07-95
 995 --------------------
 996
 997 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 998 one interrupt pending)
 999
1000 * Fixed updating of condition codes during logical instructions (carry and
1001 overflow were not reset)
1002
1003 * Fixed bug in WRTBR (tt field was wrongly over-written)
1004
1005 version 1.1 07-07-95
1006 --------------------
1007
1008 * Fixed several bugs in the interrupt handler and callback routines.
1009 (reported by Paul Warren, Alsys)
