494 * configure: regenerate
496 1999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
498 * exec.c (dispatch_instruction):
499 Correct the sense of the
501 sregs->trap = TRAP_UNIMP;
504 clause that has been pasted around: it's correct in the SCAN and
505 DIVScc (divide step) cases (where it was probably originally
506 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
507 ie. instructions only in the SPARC V8 or SPARClite 86x
508 architectures. It was also present when not required for SMUL,
509 SMULcc, UMUL, UMULcc instructions that are present in all
512 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
514 * interf.c (run_sim): Fix a bug in the main loop's handling of
515 annulled delay slot instructions. There is precedent for this
516 change; the _other_ main loop in sis.c gets it right according to
517 my reading of the code.
519 The bug is: if an interrupt happens when the next instruction
520 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
521 with the current values of PC and NPC, so when the trap returns,
522 the annulled instruction is indeed executed. Another giveaway is
523 that the annul flag is cleared in execute_trap(): the information
524 is demonstrably discarded.
526 The solution is: perform annulling before looking for traps, in
527 fact it's neater to do annulling, see if there's an interrupt and
528 if not, do the instruction, then handle traps be they generated by
529 interrupts pending or by the instruction we might just have done.
530 That's what the sis.c one does.
532 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
534 * sis.h: Add asr17 register for support of SparcLITE (at least the
535 Hitachi ones I find before me)
537 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
538 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
539 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
540 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
541 (init_regs): Initialize y and asr17.
542 NB: In instruction-set space, the Y register is asr0; the
543 instructions have different names for human reasons only.
546 * interf.c: Set boolean mode variable dumbio if invoked with
547 argument "-dumbio" and mention it of verbose.
548 * erc32.c: if "dumbio" is set, do not assume that there is a
549 terminal type device attached to stdin/stdout. Do not set
550 buffering or mess with tcsetattr or do any read operations in
551 order to make UART interrupts; not input data is supported.
552 This is necessary to allow the sim to be used within the eCos
553 testing infrastructure where stdin/stdout are pipes to a TCL
554 program; the sim hangs otherwise.
556 Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com>

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

581 to allow emulation of SPARClite board RAM.
582 (fetch_bytes, store_bytes): New helper functions for revamped
583 mememory_read and memory_write.

585 byte order instead of storing words in host byte order; this
586 greatly simplifies support of little-endian programs.
587 (get_mem_ptr): Remove unnecessary byte parameter.
588 (sis_memory_write, sis_memory_read): Store words in target
589 byte order instead of host byte order.

592 (memory_read): Add new sz parameter.
593 * sis.c (run_sim): Use revamped memory_read, which makes
594 byte-swapping unnecessary.
595 * exec.c (dispatch_instruction): Use revamped memory_read, which
596 makes byte-swapping and double-word fetching unnecessary.
597 * func.c (sparclite_board): Declare new variable.

984 but no FPU trap is generated.
986 version 1.7.1 31-10-95
989 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
990 the FPU stays in execute mode.

1001 version 1.6.2 25-10-95
1002 --------------------
1004 * Added -DFAST_UART to Makefile

1014 --------------------
1016 * Modified srt0.s to include code that initiates registers in IU and FPU
1017 and initializes the data segment. The simulator 'load' command does not
1018 longer initialize the data segment!
1020 * Corrected MEC timer operation; scalers now divide the frequency by
1023 * MEC breakpoints are not checked during store operation
1026 version 1.5 14-09-95
1027 --------------------
1029 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1031 * Fixed bug that allowed an annuled instruction to cause memory exception.
1033 * The *ws parameter in mem.c should now contain the number of waitstates
1034 required by the memory access (was total number of cycles).
1036 * The supplied srt0.s now clears the BSS (thanks Joel).
1038 version 1.4 22-08-95
1039 --------------------
1041 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1042 some problems on solaris 2.x machines.
1044 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1045 may suffer a bit ...
1047 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1049 version 1.3 26-07-95
1050 --------------------
1052 * Fixed bug in mulscc instruction (how could that ever have worked?)
1054 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1056 version 1.2 13-07-95
1057 --------------------
1059 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1060 one interrupt pending)
1062 * Fixed updating of condition codes during logical instructions (carry and
1063 overflow were not reset)
1065 * Fixed bug in WRTBR (tt field was wrongly over-written)
1067 version 1.1 07-07-95
1068 --------------------
1070 * Fixed several bugs in the interrupt handler and callback routines.
1071 (reported by Paul Warren, Alsys)
