 512 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 513

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

 594         emulating RAM found on typical SPARClite boards.  Print
 595         error message for unrecognized option.

 977         byte.
 978
 979 Version 2.1 26-02-96
 980 --------------------
 981
 982 * Fixed bug in "go" command.
 983
 984 version 2.0 05-02-96
 985 --------------------
 986
 987 * Fixed bug in interrupt force register (erc32.c).
 988
 989 * Change file load function to use bfd_openr.
 990
 991 * SIS should now be endian independent.
 992
 993 version 1.8 24-11-95
 994 --------------------
 995
 996 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 997   the resource dependencies right.
 998
 999 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
1000   but no FPU trap is generated.
1001
1002 version 1.7.1 31-10-95
1003 --------------------
1004
1005 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1006   the FPU stays in execute mode.
1007
1008 * Corrected JMPL and RETT timing (these instructions takes two cycles).
1009
1010
1011 version 1.7 25-10-95
1012 --------------------
1013
1014 * Interrupt during annuled instruction corrupted return address - fixed.
1015
1016
1017 version 1.6.2 25-10-95
1018 --------------------
1019
1020 * Added -DFAST_UART to Makefile
1021
1022
1023 version 1.6.1 24-10-95
1024 --------------------
1025
1026 * Fixed bug in STDFQ which caused bus error
1027
1028
1029 version 1.6 02-10-95
1030 --------------------
1031
1032 * Modified srt0.s to include code that initiates registers in IU and FPU
1033   and initializes the data segment. The simulator 'load' command does not
1034   longer initialize the data segment!
1035
1036 * Corrected MEC timer operation; scalers now divide the frequency by
1037   (scaler_value + 1).
1038
1039 * MEC breakpoints are not checked during store operation
1040
1041
1042 version 1.5 14-09-95
1043 --------------------
1044
1045 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1046
1047 * Fixed bug that allowed an annuled instruction to cause memory exception.
1048
1049 * The *ws parameter in mem.c should now contain the number of waitstates
1050   required by the memory access (was total number of cycles).
1051
1052 * The supplied srt0.s now clears the BSS (thanks Joel).
1053
1054 version 1.4 22-08-95
1055 --------------------
1056
1057 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1058 some problems on solaris 2.x machines.
1059
1060 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1061 may suffer a bit ...
1062
1063 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1064
1065 version 1.3 26-07-95
1066 --------------------
1067
1068 * Fixed bug in mulscc instruction (how could that ever have worked?)
1069
1070 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1071
1072 version 1.2 13-07-95
1073 --------------------
1074
1075 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1076 one interrupt pending)
1077
1078 * Fixed updating of condition codes during logical instructions (carry and
1079 overflow were not reset)
1080
1081 * Fixed bug in WRTBR (tt field was wrongly over-written)
1082
1083 version 1.1 07-07-95
1084 --------------------
1085
1086 * Fixed several bugs in the interrupt handler and callback routines.
1087 (reported by Paul Warren, Alsys)
