528 1999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
530 * exec.c (dispatch_instruction):
531 Correct the sense of the
533 sregs->trap = TRAP_UNIMP;
536 clause that has been pasted around: it's correct in the SCAN and
537 DIVScc (divide step) cases (where it was probably originally
538 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
539 ie. instructions only in the SPARC V8 or SPARClite 86x
540 architectures. It was also present when not required for SMUL,
541 SMULcc, UMUL, UMULcc instructions that are present in all
544 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
546 * interf.c (run_sim): Fix a bug in the main loop's handling of
547 annulled delay slot instructions. There is precedent for this
548 change; the _other_ main loop in sis.c gets it right according to
549 my reading of the code.
551 The bug is: if an interrupt happens when the next instruction
552 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
553 with the current values of PC and NPC, so when the trap returns,
554 the annulled instruction is indeed executed. Another giveaway is
555 that the annul flag is cleared in execute_trap(): the information
556 is demonstrably discarded.
558 The solution is: perform annulling before looking for traps, in
559 fact it's neater to do annulling, see if there's an interrupt and
560 if not, do the instruction, then handle traps be they generated by
561 interrupts pending or by the instruction we might just have done.
562 That's what the sis.c one does.
564 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
566 * sis.h: Add asr17 register for support of SparcLITE (at least the
567 Hitachi ones I find before me)
569 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
570 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
571 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
572 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
573 (init_regs): Initialize y and asr17.
574 NB: In instruction-set space, the Y register is asr0; the
575 instructions have different names for human reasons only.
578 * interf.c: Set boolean mode variable dumbio if invoked with
579 argument "-dumbio" and mention it of verbose.
580 * erc32.c: if "dumbio" is set, do not assume that there is a
581 terminal type device attached to stdin/stdout. Do not set
582 buffering or mess with tcsetattr or do any read operations in
583 order to make UART interrupts; not input data is supported.
584 This is necessary to allow the sim to be used within the eCos
585 testing infrastructure where stdin/stdout are pipes to a TCL
586 program; the sim hangs otherwise.

590 * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.

606 Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com>
608 * interf.c (sim_open): Use revamped memory_read, which makes
609 byte-swapping unnecessary. Add -sparclite-board option for
610 emulating RAM found on typical SPARClite boards. Print
611 error message for unrecognized option.

1000 version 2.0 05-02-96
1001 --------------------
1003 * Fixed bug in interrupt force register (erc32.c).
1005 * Change file load function to use bfd_openr.
1007 * SIS should now be endian independent.
1009 version 1.8 24-11-95
1010 --------------------
1012 * Fixed FPU timing - some sequences of FPU instructions did not calculate
1013 the resource dependencies right.
1015 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
1016 but no FPU trap is generated.
1018 version 1.7.1 31-10-95
1019 --------------------
1021 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1022 the FPU stays in execute mode.
1024 * Corrected JMPL and RETT timing (these instructions takes two cycles).
1027 version 1.7 25-10-95
1028 --------------------
1030 * Interrupt during annuled instruction corrupted return address - fixed.
1033 version 1.6.2 25-10-95
1034 --------------------
1036 * Added -DFAST_UART to Makefile
1039 version 1.6.1 24-10-95
1040 --------------------
1042 * Fixed bug in STDFQ which caused bus error
1045 version 1.6 02-10-95
1046 --------------------
1048 * Modified srt0.s to include code that initiates registers in IU and FPU
1049 and initializes the data segment. The simulator 'load' command does not
1050 longer initialize the data segment!
1052 * Corrected MEC timer operation; scalers now divide the frequency by
1055 * MEC breakpoints are not checked during store operation
1058 version 1.5 14-09-95
1059 --------------------
1061 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1063 * Fixed bug that allowed an annuled instruction to cause memory exception.
1065 * The *ws parameter in mem.c should now contain the number of waitstates
1066 required by the memory access (was total number of cycles).
1068 * The supplied srt0.s now clears the BSS (thanks Joel).
1070 version 1.4 22-08-95
1071 --------------------
1073 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1074 some problems on solaris 2.x machines.
1076 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1077 may suffer a bit ...
1079 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1081 version 1.3 26-07-95
1082 --------------------
1084 * Fixed bug in mulscc instruction (how could that ever have worked?)
1086 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1088 version 1.2 13-07-95
1089 --------------------
1091 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1092 one interrupt pending)
1094 * Fixed updating of condition codes during logical instructions (carry and
1095 overflow were not reset)
1097 * Fixed bug in WRTBR (tt field was wrongly over-written)
1099 version 1.1 07-07-95
1100 --------------------
1102 * Fixed several bugs in the interrupt handler and callback routines.
1103 (reported by Paul Warren, Alsys)
