475 1999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
477 * exec.c (dispatch_instruction):
478 Correct the sense of the
480 sregs->trap = TRAP_UNIMP;
483 clause that has been pasted around: it's correct in the SCAN and
484 DIVScc (divide step) cases (where it was probably originally
485 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
486 ie. instructions only in the SPARC V8 or SPARClite 86x
487 architectures. It was also present when not required for SMUL,
488 SMULcc, UMUL, UMULcc instructions that are present in all
491 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
493 * interf.c (run_sim): Fix a bug in the main loop's handling of
494 annulled delay slot instructions. There is precedent for this
495 change; the _other_ main loop in sis.c gets it right according to
496 my reading of the code.
498 The bug is: if an interrupt happens when the next instruction
499 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
500 with the current values of PC and NPC, so when the trap returns,
501 the annulled instruction is indeed executed. Another giveaway is
502 that the annul flag is cleared in execute_trap(): the information
503 is demonstrably discarded.
505 The solution is: perform annulling before looking for traps, in
506 fact it's neater to do annulling, see if there's an interrupt and
507 if not, do the instruction, then handle traps be they generated by
508 interrupts pending or by the instruction we might just have done.
509 That's what the sis.c one does.
511 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
513 * sis.h: Add asr17 register for support of SparcLITE (at least the
514 Hitachi ones I find before me)
516 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
517 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
518 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
519 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
520 (init_regs): Initialize y and asr17.
521 NB: In instruction-set space, the Y register is asr0; the
522 instructions have different names for human reasons only.
525 * interf.c: Set boolean mode variable dumbio if invoked with
526 argument "-dumbio" and mention it of verbose.
527 * erc32.c: if "dumbio" is set, do not assume that there is a
528 terminal type device attached to stdin/stdout. Do not set
529 buffering or mess with tcsetattr or do any read operations in
530 order to make UART interrupts; not input data is supported.
531 This is necessary to allow the sim to be used within the eCos
532 testing infrastructure where stdin/stdout are pipes to a TCL
533 program; the sim hangs otherwise.

556 byte-swapping unnecessary. Add -sparclite-board option for
557 emulating RAM found on typical SPARClite boards. Print

561 (fetch_bytes, store_bytes): New helper functions for revamped
562 mememory_read and memory_write.

573 byte-swapping unnecessary.

950 * Fixed bug in interrupt force register (erc32.c).
952 * Change file load function to use bfd_openr.
954 * SIS should now be endian independent.
959 * Fixed FPU timing - some sequences of FPU instructions did not calculate
960 the resource dependencies right.

963 but no FPU trap is generated.
965 version 1.7.1 31-10-95
968 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
969 the FPU stays in execute mode.
971 * Corrected JMPL and RETT timing (these instructions takes two cycles).
977 * Interrupt during annuled instruction corrupted return address - fixed.
980 version 1.6.2 25-10-95

989 * Fixed bug in STDFQ which caused bus error
995 * Modified srt0.s to include code that initiates registers in IU and FPU
996 and initializes the data segment. The simulator 'load' command does not
997 longer initialize the data segment!
999 * Corrected MEC timer operation; scalers now divide the frequency by
1002 * MEC breakpoints are not checked during store operation
1005 version 1.5 14-09-95
1006 --------------------
1008 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1010 * Fixed bug that allowed an annuled instruction to cause memory exception.
1012 * The *ws parameter in mem.c should now contain the number of waitstates
1013 required by the memory access (was total number of cycles).
1015 * The supplied srt0.s now clears the BSS (thanks Joel).
1017 version 1.4 22-08-95
1018 --------------------
1020 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1021 some problems on solaris 2.x machines.
1023 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1024 may suffer a bit ...
1026 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1028 version 1.3 26-07-95
1029 --------------------
1031 * Fixed bug in mulscc instruction (how could that ever have worked?)
1033 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1035 version 1.2 13-07-95
1036 --------------------
1038 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1039 one interrupt pending)
1041 * Fixed updating of condition codes during logical instructions (carry and
1042 overflow were not reset)
1044 * Fixed bug in WRTBR (tt field was wrongly over-written)
1046 version 1.1 07-07-95
1047 --------------------
1049 * Fixed several bugs in the interrupt handler and callback routines.
1050 (reported by Paul Warren, Alsys)
