 454 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 455
 456         * exec.c (dispatch_instruction):
 457         Correct the sense of the
 458                   if (!sparclite) {
 459                      sregs->trap = TRAP_UNIMP;
 460                      break;
 461                   }
 462         clause that has been pasted around: it's correct in the SCAN and
 463         DIVScc (divide step) cases (where it was probably originally
 464         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 465         ie. instructions only in the SPARC V8 or SPARClite 86x
 466         architectures.  It was also present when not required for SMUL,
 467         SMULcc, UMUL, UMULcc instructions that are present in all
 468         architectures.
 469
 470 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 471
 472         * interf.c (run_sim): Fix a bug in the main loop's handling of
 473         annulled delay slot instructions.  There is precedent for this
 474         change; the _other_ main loop in sis.c gets it right according to
 475         my reading of the code.
 476
 477         The bug is: if an interrupt happens when the next instruction
 478         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 479         with the current values of PC and NPC, so when the trap returns,
 480         the annulled instruction is indeed executed.  Another giveaway is
 481         that the annul flag is cleared in execute_trap(): the information
 482         is demonstrably discarded.
 483
 484         The solution is: perform annulling before looking for traps, in
 485         fact it's neater to do annulling, see if there's an interrupt and
 486         if not, do the instruction, then handle traps be they generated by
 487         interrupts pending or by the instruction we might just have done.
 488         That's what the sis.c one does.
 489
 490 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 491
 492         * sis.h: Add asr17 register for support of SparcLITE (at least the
 493         Hitachi ones I find before me)
 494
 495         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 496         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 497         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 498         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 499         (init_regs): Initialize y and asr17.
 500         NB: In instruction-set space, the Y register is asr0; the
 501         instructions have different names for human reasons only.
 502
 503         * sis.c:
 504         * interf.c: Set boolean mode variable dumbio if invoked with
 505         argument "-dumbio" and mention it of verbose.
 506         * erc32.c: if "dumbio" is set, do not assume that there is a
 507         terminal type device attached to stdin/stdout.  Do not set
 508         buffering or mess with tcsetattr or do any read operations in
 509         order to make UART interrupts; not input data is supported.
 510         This is necessary to allow the sim to be used within the eCos
 511         testing infrastructure where stdin/stdout are pipes to a TCL
 512         program; the sim hangs otherwise.

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

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

 919         byte.
 920
 921 Version 2.1 26-02-96
 922 --------------------
 923
 924 * Fixed bug in "go" command.
 925
 926 version 2.0 05-02-96
 927 --------------------
 928
 929 * Fixed bug in interrupt force register (erc32.c).
 930
 931 * Change file load function to use bfd_openr.
 932
 933 * SIS should now be endian independent.
 934
 935 version 1.8 24-11-95
 936 --------------------
 937
 938 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 939   the resource dependencies right.
 940
 941 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 942   but no FPU trap is generated.
 943
 944 version 1.7.1 31-10-95
 945 --------------------
 946
 947 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 948   the FPU stays in execute mode.
 949
 950 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 951
 952
 953 version 1.7 25-10-95
 954 --------------------
 955
 956 * Interrupt during annuled instruction corrupted return address - fixed.
 957
 958
 959 version 1.6.2 25-10-95
 960 --------------------
 961
 962 * Added -DFAST_UART to Makefile
 963
 964
 965 version 1.6.1 24-10-95
 966 --------------------
 967
 968 * Fixed bug in STDFQ which caused bus error
 969
 970
 971 version 1.6 02-10-95
 972 --------------------
 973
 974 * Modified srt0.s to include code that initiates registers in IU and FPU
 975   and initializes the data segment. The simulator 'load' command does not
 976   longer initialize the data segment!
 977
 978 * Corrected MEC timer operation; scalers now divide the frequency by
 979   (scaler_value + 1).
 980
 981 * MEC breakpoints are not checked during store operation
 982
 983
 984 version 1.5 14-09-95
 985 --------------------
 986
 987 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 988
 989 * Fixed bug that allowed an annuled instruction to cause memory exception.
 990
 991 * The *ws parameter in mem.c should now contain the number of waitstates
 992   required by the memory access (was total number of cycles).
 993
 994 * The supplied srt0.s now clears the BSS (thanks Joel).
 995
 996 version 1.4 22-08-95
 997 --------------------
 998
 999 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1000 some problems on solaris 2.x machines.
1001
1002 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1003 may suffer a bit ...
1004
1005 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1006
1007 version 1.3 26-07-95
1008 --------------------
1009
1010 * Fixed bug in mulscc instruction (how could that ever have worked?)
1011
1012 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1013
1014 version 1.2 13-07-95
1015 --------------------
1016
1017 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1018 one interrupt pending)
1019
1020 * Fixed updating of condition codes during logical instructions (carry and
1021 overflow were not reset)
1022
1023 * Fixed bug in WRTBR (tt field was wrongly over-written)
1024
1025 version 1.1 07-07-95
1026 --------------------
1027
1028 * Fixed several bugs in the interrupt handler and callback routines.
1029 (reported by Paul Warren, Alsys)
