426 Correct the sense of the
427 if (!sparclite) {
428 sregs->trap = TRAP_UNIMP;
429 break;
430 }
431 clause that has been pasted around: it's correct in the SCAN and
432 DIVScc (divide step) cases (where it was probably originally
433 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
434 ie. instructions only in the SPARC V8 or SPARClite 86x
435 architectures. It was also present when not required for SMUL,
436 SMULcc, UMUL, UMULcc instructions that are present in all
437 architectures.
438
4391999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
440
441 * interf.c (run_sim): Fix a bug in the main loop's handling of
442 annulled delay slot instructions. There is precedent for this
443 change; the _other_ main loop in sis.c gets it right according to
444 my reading of the code.
445
446 The bug is: if an interrupt happens when the next instruction
447 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
448 with the current values of PC and NPC, so when the trap returns,
449 the annulled instruction is indeed executed. Another giveaway is
450 that the annul flag is cleared in execute_trap(): the information
451 is demonstrably discarded.
452
453 The solution is: perform annulling before looking for traps, in
454 fact it's neater to do annulling, see if there's an interrupt and
455 if not, do the instruction, then handle traps be they generated by
456 interrupts pending or by the instruction we might just have done.
457 That's what the sis.c one does.

4591999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
460
461 * sis.h: Add asr17 register for support of SparcLITE (at least the
462 Hitachi ones I find before me)
463
464 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
465 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
466 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
467 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
468 (init_regs): Initialize y and asr17.
469 NB: In instruction-set space, the Y register is asr0; the
470 instructions have different names for human reasons only.
471
472 * sis.c:
473 * interf.c: Set boolean mode variable dumbio if invoked with
474 argument "-dumbio" and mention it of verbose.
475 * erc32.c: if "dumbio" is set, do not assume that there is a
476 terminal type device attached to stdin/stdout. Do not set
477 buffering or mess with tcsetattr or do any read operations in
478 order to make UART interrupts; not input data is supported.
479 This is necessary to allow the sim to be used within the eCos
480 testing infrastructure where stdin/stdout are pipes to a TCL
481 program; the sim hangs otherwise.
482
483Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com>

504 byte-swapping unnecessary. Add -sparclite-board option for
505 emulating RAM found on typical SPARClite boards. Print
506 error message for unrecognized option.

508 to allow emulation of SPARClite board RAM.
509 (fetch_bytes, store_bytes): New helper functions for revamped
510 mememory_read and memory_write.
511 (memory_read, memory_write): Rewrite to store bytes in target
512 byte order instead of storing words in host byte order; this
513 greatly simplifies support of little-endian programs.
514 (get_mem_ptr): Remove unnecessary byte parameter.
515 (sis_memory_write, sis_memory_read): Store words in target
516 byte order instead of host byte order.

518 * sis.h ((byte_swap_words): Remove declaration, no longer needed.
519 (memory_read): Add new sz parameter.
520 * sis.c (run_sim): Use revamped memory_read, which makes
521 byte-swapping unnecessary.

523 makes byte-swapping and double-word fetching unnecessary.
524 * func.c (sparclite_board): Declare new variable.
525 (get_regi): Handle little-endian data.
526 (bfd_load): Recognize little-endian SPARClite as having
527 little-endian data.

549 * interf.c (run_sim): Always fetch instructions as big-endian.

898* Fixed bug in interrupt force register (erc32.c).
899
900* Change file load function to use bfd_openr.
901
902* SIS should now be endian independent.
903
904version 1.8 24-11-95
905--------------------
906
907* Fixed FPU timing - some sequences of FPU instructions did not calculate
908 the resource dependencies right.
909
910* Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
911 but no FPU trap is generated.
912
913version 1.7.1 31-10-95
914--------------------
915
916* Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
917 the FPU stays in execute mode.
918
919* Corrected JMPL and RETT timing (these instructions takes two cycles).
920
921
922version 1.7 25-10-95
923--------------------
924
925* Interrupt during annuled instruction corrupted return address - fixed.
926
927
928version 1.6.2 25-10-95
929--------------------
930
931* Added -DFAST_UART to Makefile
932
933
934version 1.6.1 24-10-95
935--------------------
936
937* Fixed bug in STDFQ which caused bus error
938
939
940version 1.6 02-10-95
941--------------------
942
943* Modified srt0.s to include code that initiates registers in IU and FPU
944 and initializes the data segment. The simulator 'load' command does not
945 longer initialize the data segment!
946
947* Corrected MEC timer operation; scalers now divide the frequency by
948 (scaler_value + 1).
949
950* MEC breakpoints are not checked during store operation
951
952
953version 1.5 14-09-95
954--------------------
955
956* Fixed some bugs in the cycle counting for IU & FPU instructions.
957
958* Fixed bug that allowed an annuled instruction to cause memory exception.
959
960* The *ws parameter in mem.c should now contain the number of waitstates
961 required by the memory access (was total number of cycles).
962
963* The supplied srt0.s now clears the BSS (thanks Joel).
964
965version 1.4 22-08-95
966--------------------
967
968* Added a '-g' switch to enable/disable the GNU readline(), which cause
969some problems on solaris 2.x machines.
970
971* Enabled MEC watchpoint and breakpoint function to mem.c. Performance
972may suffer a bit ...
973
974NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
975
976version 1.3 26-07-95
977--------------------
978
979* Fixed bug in mulscc instruction (how could that ever have worked?)
980
981* Fixed bug in UART B (flushed characters on UART A), thanks Paul.
982
983version 1.2 13-07-95
984--------------------
985
986* Fixed bug in interrupt handling (wrong interrupt selected when more that
987one interrupt pending)
988
989* Fixed updating of condition codes during logical instructions (carry and
990overflow were not reset)
991
992* Fixed bug in WRTBR (tt field was wrongly over-written)
993
994version 1.1 07-07-95
995--------------------
996
997* Fixed several bugs in the interrupt handler and callback routines.
