72f4393d 536 * exec.c (dispatch_instruction):
c906108c
SS		 537 Correct the sense of the
538 if (!sparclite) {
539 sregs->trap = TRAP_UNIMP;
72f4393d 540 break;
c906108c
SS		 541 }
542 clause that has been pasted around: it's correct in the SCAN and
543 DIVScc (divide step) cases (where it was probably originally
544 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
545 ie. instructions only in the SPARC V8 or SPARClite 86x
546 architectures. It was also present when not required for SMUL,
547 SMULcc, UMUL, UMULcc instructions that are present in all
548 architectures.
549
5501999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
551
552 * interf.c (run_sim): Fix a bug in the main loop's handling of
553 annulled delay slot instructions. There is precedent for this
554 change; the _other_ main loop in sis.c gets it right according to
555 my reading of the code.
556
557 The bug is: if an interrupt happens when the next instruction
558 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
559 with the current values of PC and NPC, so when the trap returns,
560 the annulled instruction is indeed executed. Another giveaway is
561 that the annul flag is cleared in execute_trap(): the information
562 is demonstrably discarded.
563
564 The solution is: perform annulling before looking for traps, in
565 fact it's neater to do annulling, see if there's an interrupt and
566 if not, do the instruction, then handle traps be they generated by
567 interrupts pending or by the instruction we might just have done.
568 That's what the sis.c one does.
569
5701999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
571
572 * sis.h: Add asr17 register for support of SparcLITE (at least the
573 Hitachi ones I find before me)
574
575 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
576 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
577 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
578 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
579 (init_regs): Initialize y and asr17.
580 NB: In instruction-set space, the Y register is asr0; the
581 instructions have different names for human reasons only.
582
583 * sis.c:
584 * interf.c: Set boolean mode variable dumbio if invoked with
585 argument "-dumbio" and mention it of verbose.
586 * erc32.c: if "dumbio" is set, do not assume that there is a
587 terminal type device attached to stdin/stdout. Do not set
588 buffering or mess with tcsetattr or do any read operations in
589 order to make UART interrupts; not input data is supported.
590 This is necessary to allow the sim to be used within the eCos
591 testing infrastructure where stdin/stdout are pipes to a TCL
592 program; the sim hangs otherwise.

615 byte-swapping unnecessary. Add -sparclite-board option for
616 emulating RAM found on typical SPARClite boards. Print
617 error message for unrecognized option.

619 to allow emulation of SPARClite board RAM.
620 (fetch_bytes, store_bytes): New helper functions for revamped
621 mememory_read and memory_write.
622 (memory_read, memory_write): Rewrite to store bytes in target
623 byte order instead of storing words in host byte order; this
624 greatly simplifies support of little-endian programs.
625 (get_mem_ptr): Remove unnecessary byte parameter.
626 (sis_memory_write, sis_memory_read): Store words in target

946
947 * erc32.c: Don't include sys/ioctl.h or sys/file.h. They aren't
948 necessary.

1001Version 2.1 26-02-96
1002--------------------
72f4393d 1003
c906108c 1004* Fixed bug in "go" command.
72f4393d 1005
c906108c
SS		 1006version 2.0 05-02-96
1007--------------------
1008
1009* Fixed bug in interrupt force register (erc32.c).
1010
1011* Change file load function to use bfd_openr.
1012
1013* SIS should now be endian independent.
1014
1015version 1.8 24-11-95
1016--------------------
1017
1018* Fixed FPU timing - some sequences of FPU instructions did not calculate
1019 the resource dependencies right.
1020
1021* Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
1022 but no FPU trap is generated.
1023
1024version 1.7.1 31-10-95
1025--------------------
1026
1027* Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1028 the FPU stays in execute mode.
1029
1030* Corrected JMPL and RETT timing (these instructions takes two cycles).
1031
1032
1033version 1.7 25-10-95
1034--------------------
1035
1036* Interrupt during annuled instruction corrupted return address - fixed.
1037
1038
1039version 1.6.2 25-10-95
1040--------------------
1041
1042* Added -DFAST_UART to Makefile
72f4393d 1043
c906108c
SS		 1044
1045version 1.6.1 24-10-95
1046--------------------
72f4393d 1047
c906108c
SS		 1048* Fixed bug in STDFQ which caused bus error
1049
1050
1051version 1.6 02-10-95
1052--------------------
72f4393d 1053
c906108c
SS		 1054* Modified srt0.s to include code that initiates registers in IU and FPU
1055 and initializes the data segment. The simulator 'load' command does not
1056 longer initialize the data segment!
1057
72f4393d 1058* Corrected MEC timer operation; scalers now divide the frequency by
c906108c
SS		 1059 (scaler_value + 1).
1060
1061* MEC breakpoints are not checked during store operation
1062
1063
1064version 1.5 14-09-95
1065--------------------
1066
1067* Fixed some bugs in the cycle counting for IU & FPU instructions.
1068
1069* Fixed bug that allowed an annuled instruction to cause memory exception.
1070
1071* The *ws parameter in mem.c should now contain the number of waitstates
1072 required by the memory access (was total number of cycles).
1073
1074* The supplied srt0.s now clears the BSS (thanks Joel).
1075
1076version 1.4 22-08-95
1077--------------------
1078
1079* Added a '-g' switch to enable/disable the GNU readline(), which cause
1080some problems on solaris 2.x machines.
1081
72f4393d 1082* Enabled MEC watchpoint and breakpoint function to mem.c. Performance
c906108c
SS		 1083may suffer a bit ...
1084
1085NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1086
1087version 1.3 26-07-95
1088--------------------
1089
1090* Fixed bug in mulscc instruction (how could that ever have worked?)
1091
1092* Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1093
1094version 1.2 13-07-95
1095--------------------
1096
1097* Fixed bug in interrupt handling (wrong interrupt selected when more that
1098one interrupt pending)
1099
1100* Fixed updating of condition codes during logical instructions (carry and
1101overflow were not reset)
1102
1103* Fixed bug in WRTBR (tt field was wrongly over-written)
1104
1105version 1.1 07-07-95
1106--------------------
1107
1108* Fixed several bugs in the interrupt handler and callback routines.
