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

594 Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com>
596 * interf.c (sim_open): Use revamped memory_read, which makes
597 byte-swapping unnecessary. Add -sparclite-board option for
598 emulating RAM found on typical SPARClite boards. Print
599 error message for unrecognized option.
600 * erc32.c: Change RAM address and size from constants to variables,
601 to allow emulation of SPARClite board RAM.
602 (fetch_bytes, store_bytes): New helper functions for revamped
603 mememory_read and memory_write.
604 (memory_read, memory_write): Rewrite to store bytes in target
605 byte order instead of storing words in host byte order; this
606 greatly simplifies support of little-endian programs.

1001 the resource dependencies right.
1003 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
1004 but no FPU trap is generated.
1006 version 1.7.1 31-10-95
1007 --------------------
1009 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1010 the FPU stays in execute mode.
1012 * Corrected JMPL and RETT timing (these instructions takes two cycles).
1015 version 1.7 25-10-95
1016 --------------------

1034 --------------------
1036 * Modified srt0.s to include code that initiates registers in IU and FPU
1037 and initializes the data segment. The simulator 'load' command does not
1038 longer initialize the data segment!
1040 * Corrected MEC timer operation; scalers now divide the frequency by
1043 * MEC breakpoints are not checked during store operation
1046 version 1.5 14-09-95
1047 --------------------
1049 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1051 * Fixed bug that allowed an annuled instruction to cause memory exception.
1053 * The *ws parameter in mem.c should now contain the number of waitstates
1054 required by the memory access (was total number of cycles).
1056 * The supplied srt0.s now clears the BSS (thanks Joel).
1058 version 1.4 22-08-95
1059 --------------------
1061 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1062 some problems on solaris 2.x machines.
1064 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1065 may suffer a bit ...
1067 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1069 version 1.3 26-07-95
1070 --------------------
1072 * Fixed bug in mulscc instruction (how could that ever have worked?)
1074 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1076 version 1.2 13-07-95
1077 --------------------
1079 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1080 one interrupt pending)
1082 * Fixed updating of condition codes during logical instructions (carry and
1083 overflow were not reset)
1085 * Fixed bug in WRTBR (tt field was wrongly over-written)
1087 version 1.1 07-07-95
1088 --------------------
1090 * Fixed several bugs in the interrupt handler and callback routines.
1091 (reported by Paul Warren, Alsys)
