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

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

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

 580         * sis.c (run_sim): Use revamped memory_read, which makes

 948         byte.
 949
 950 Version 2.1 26-02-96
 951 --------------------
 952
 953 * Fixed bug in "go" command.
 954
 955 version 2.0 05-02-96
 956 --------------------
 957
 958 * Fixed bug in interrupt force register (erc32.c).
 959
 960 * Change file load function to use bfd_openr.
 961
 962 * SIS should now be endian independent.
 963
 964 version 1.8 24-11-95
 965 --------------------
 966
 967 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 968   the resource dependencies right.
 969
 970 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 971   but no FPU trap is generated.
 972
 973 version 1.7.1 31-10-95
 974 --------------------
 975
 976 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 977   the FPU stays in execute mode.
 978
 979 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 980
 981
 982 version 1.7 25-10-95
 983 --------------------
 984
 985 * Interrupt during annuled instruction corrupted return address - fixed.
 986
 987
 988 version 1.6.2 25-10-95
 989 --------------------
 990
 991 * Added -DFAST_UART to Makefile
 992
 993
 994 version 1.6.1 24-10-95
 995 --------------------
 996
 997 * Fixed bug in STDFQ which caused bus error
 998
 999
1000 version 1.6 02-10-95
1001 --------------------
1002
1003 * Modified srt0.s to include code that initiates registers in IU and FPU
1004   and initializes the data segment. The simulator 'load' command does not
1005   longer initialize the data segment!
1006
1007 * Corrected MEC timer operation; scalers now divide the frequency by
1008   (scaler_value + 1).
1009
1010 * MEC breakpoints are not checked during store operation
1011
1012
1013 version 1.5 14-09-95
1014 --------------------
1015
1016 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1017
1018 * Fixed bug that allowed an annuled instruction to cause memory exception.
1019
1020 * The *ws parameter in mem.c should now contain the number of waitstates
1021   required by the memory access (was total number of cycles).
1022
1023 * The supplied srt0.s now clears the BSS (thanks Joel).
1024
1025 version 1.4 22-08-95
1026 --------------------
1027
1028 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1029 some problems on solaris 2.x machines.
1030
1031 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1032 may suffer a bit ...
1033
1034 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1035
1036 version 1.3 26-07-95
1037 --------------------
1038
1039 * Fixed bug in mulscc instruction (how could that ever have worked?)
1040
1041 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1042
1043 version 1.2 13-07-95
1044 --------------------
1045
1046 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1047 one interrupt pending)
1048
1049 * Fixed updating of condition codes during logical instructions (carry and
1050 overflow were not reset)
1051
1052 * Fixed bug in WRTBR (tt field was wrongly over-written)
1053
1054 version 1.1 07-07-95
1055 --------------------
1056
1057 * Fixed several bugs in the interrupt handler and callback routines.
1058 (reported by Paul Warren, Alsys)
