72f4393d 522 * exec.c (dispatch_instruction):
c906108c
SS		 523 Correct the sense of the
524 if (!sparclite) {
525 sregs->trap = TRAP_UNIMP;
72f4393d 526 break;
c906108c
SS		 527 }
528 clause that has been pasted around: it's correct in the SCAN and
529 DIVScc (divide step) cases (where it was probably originally
530 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
531 ie. instructions only in the SPARC V8 or SPARClite 86x
532 architectures. It was also present when not required for SMUL,
533 SMULcc, UMUL, UMULcc instructions that are present in all
534 architectures.
535
5361999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
537
538 * interf.c (run_sim): Fix a bug in the main loop's handling of
539 annulled delay slot instructions. There is precedent for this
540 change; the _other_ main loop in sis.c gets it right according to
541 my reading of the code.
542
543 The bug is: if an interrupt happens when the next instruction
544 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
545 with the current values of PC and NPC, so when the trap returns,
546 the annulled instruction is indeed executed. Another giveaway is
547 that the annul flag is cleared in execute_trap(): the information
548 is demonstrably discarded.
549
550 The solution is: perform annulling before looking for traps, in
551 fact it's neater to do annulling, see if there's an interrupt and
552 if not, do the instruction, then handle traps be they generated by
553 interrupts pending or by the instruction we might just have done.
554 That's what the sis.c one does.
555
5561999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
557
558 * sis.h: Add asr17 register for support of SparcLITE (at least the
559 Hitachi ones I find before me)
560
561 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
562 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
563 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
564 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
565 (init_regs): Initialize y and asr17.
566 NB: In instruction-set space, the Y register is asr0; the
567 instructions have different names for human reasons only.
568
569 * sis.c:
570 * interf.c: Set boolean mode variable dumbio if invoked with
571 argument "-dumbio" and mention it of verbose.
572 * erc32.c: if "dumbio" is set, do not assume that there is a
573 terminal type device attached to stdin/stdout. Do not set
574 buffering or mess with tcsetattr or do any read operations in
575 order to make UART interrupts; not input data is supported.
576 This is necessary to allow the sim to be used within the eCos
577 testing infrastructure where stdin/stdout are pipes to a TCL
578 program; the sim hangs otherwise.

605 to allow emulation of SPARClite board RAM.
606 (fetch_bytes, store_bytes): New helper functions for revamped
607 mememory_read and memory_write.

610 greatly simplifies support of little-endian programs.

612 (sis_memory_write, sis_memory_read): Store words in target

932
933 * erc32.c: Don't include sys/ioctl.h or sys/file.h. They aren't

986
987Version 2.1 26-02-96
988--------------------
72f4393d 989
c906108c 990* Fixed bug in "go" command.
72f4393d 991
c906108c
SS		 992version 2.0 05-02-96
993--------------------
994
995* Fixed bug in interrupt force register (erc32.c).
996
997* Change file load function to use bfd_openr.
998
999* SIS should now be endian independent.
1000
1001version 1.8 24-11-95
1002--------------------
1003
1004* Fixed FPU timing - some sequences of FPU instructions did not calculate
1005 the resource dependencies right.
1006
1007* Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
1008 but no FPU trap is generated.
1009
1010version 1.7.1 31-10-95
1011--------------------
1012
1013* Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1014 the FPU stays in execute mode.
1015
1016* Corrected JMPL and RETT timing (these instructions takes two cycles).
1017
1018
1019version 1.7 25-10-95
1020--------------------
1021
1022* Interrupt during annuled instruction corrupted return address - fixed.
1023
1024
1025version 1.6.2 25-10-95
1026--------------------
1027
1028* Added -DFAST_UART to Makefile
72f4393d 1029
c906108c
SS		 1030
1031version 1.6.1 24-10-95
1032--------------------
72f4393d 1033
c906108c
SS		 1034* Fixed bug in STDFQ which caused bus error
1035
1036
1037version 1.6 02-10-95
1038--------------------
72f4393d 1039
c906108c
SS		 1040* Modified srt0.s to include code that initiates registers in IU and FPU
1041 and initializes the data segment. The simulator 'load' command does not
1042 longer initialize the data segment!
1043
72f4393d 1044* Corrected MEC timer operation; scalers now divide the frequency by
c906108c
SS		 1045 (scaler_value + 1).
1046
1047* MEC breakpoints are not checked during store operation
1048
1049
1050version 1.5 14-09-95
1051--------------------
1052
1053* Fixed some bugs in the cycle counting for IU & FPU instructions.
1054
1055* Fixed bug that allowed an annuled instruction to cause memory exception.
1056
1057* The *ws parameter in mem.c should now contain the number of waitstates
1058 required by the memory access (was total number of cycles).
1059
1060* The supplied srt0.s now clears the BSS (thanks Joel).
1061
1062version 1.4 22-08-95
1063--------------------
1064
1065* Added a '-g' switch to enable/disable the GNU readline(), which cause
1066some problems on solaris 2.x machines.
1067
72f4393d 1068* Enabled MEC watchpoint and breakpoint function to mem.c. Performance
c906108c
SS		 1069may suffer a bit ...
1070
1071NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1072
1073version 1.3 26-07-95
1074--------------------
1075
1076* Fixed bug in mulscc instruction (how could that ever have worked?)
1077
1078* Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1079
1080version 1.2 13-07-95
1081--------------------
1082
1083* Fixed bug in interrupt handling (wrong interrupt selected when more that
1084one interrupt pending)
1085
1086* Fixed updating of condition codes during logical instructions (carry and
1087overflow were not reset)
1088
1089* Fixed bug in WRTBR (tt field was wrongly over-written)
1090
1091version 1.1 07-07-95
1092--------------------
1093
1094* Fixed several bugs in the interrupt handler and callback routines.
