SS		 4501999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
451
452 * exec.c (dispatch_instruction):
453 Correct the sense of the
454 if (!sparclite) {
455 sregs->trap = TRAP_UNIMP;
456 break;
457 }
458 clause that has been pasted around: it's correct in the SCAN and
459 DIVScc (divide step) cases (where it was probably originally
460 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
461 ie. instructions only in the SPARC V8 or SPARClite 86x
462 architectures. It was also present when not required for SMUL,
463 SMULcc, UMUL, UMULcc instructions that are present in all
464 architectures.
465
4661999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
467
468 * interf.c (run_sim): Fix a bug in the main loop's handling of
469 annulled delay slot instructions. There is precedent for this
470 change; the _other_ main loop in sis.c gets it right according to
471 my reading of the code.
472
473 The bug is: if an interrupt happens when the next instruction
474 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
475 with the current values of PC and NPC, so when the trap returns,
476 the annulled instruction is indeed executed. Another giveaway is
477 that the annul flag is cleared in execute_trap(): the information
478 is demonstrably discarded.
479
480 The solution is: perform annulling before looking for traps, in
481 fact it's neater to do annulling, see if there's an interrupt and
482 if not, do the instruction, then handle traps be they generated by
483 interrupts pending or by the instruction we might just have done.
484 That's what the sis.c one does.
485
4861999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
487
488 * sis.h: Add asr17 register for support of SparcLITE (at least the
489 Hitachi ones I find before me)
490
491 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
492 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
493 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
494 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
495 (init_regs): Initialize y and asr17.
496 NB: In instruction-set space, the Y register is asr0; the
497 instructions have different names for human reasons only.
498
499 * sis.c:
500 * interf.c: Set boolean mode variable dumbio if invoked with
501 argument "-dumbio" and mention it of verbose.
502 * erc32.c: if "dumbio" is set, do not assume that there is a
503 terminal type device attached to stdin/stdout. Do not set
504 buffering or mess with tcsetattr or do any read operations in
505 order to make UART interrupts; not input data is supported.
506 This is necessary to allow the sim to be used within the eCos
507 testing infrastructure where stdin/stdout are pipes to a TCL
508 program; the sim hangs otherwise.
509

530 * interf.c (sim_open): Use revamped memory_read, which makes
531 byte-swapping unnecessary. Add -sparclite-board option for
532 emulating RAM found on typical SPARClite boards. Print
533 error message for unrecognized option.
534 * erc32.c: Change RAM address and size from constants to variables,
535 to allow emulation of SPARClite board RAM.
536 (fetch_bytes, store_bytes): New helper functions for revamped
537 mememory_read and memory_write.
538 (memory_read, memory_write): Rewrite to store bytes in target
539 byte order instead of storing words in host byte order; this
540 greatly simplifies support of little-endian programs.
541 (get_mem_ptr): Remove unnecessary byte parameter.
542 (sis_memory_write, sis_memory_read): Store words in target
543 byte order instead of host byte order.

545 * sis.h ((byte_swap_words): Remove declaration, no longer needed.
546 (memory_read): Add new sz parameter.
547 * sis.c (run_sim): Use revamped memory_read, which makes

552 (get_regi): Handle little-endian data.
553 (bfd_load): Recognize little-endian SPARClite as having
554 little-endian data.

896Mon Jun 24 14:19:07 1996 Ian Lance Taylor <ian@cygnus.com>
897
898 * configure.in: Call AC_PROG_CC before running configure.host.
899 * configure: Rebuild with autoconf 2.10.

901Tue Jun 4 10:37:12 1996 Tom Tromey <tromey@csk3.cygnus.com>
902
903 * Makefile.in (install): Don't check to see if tooldir exists.
904 Make $(tooldir) and $(tooldir)/bin.
905
906Mon Jun 3 12:33:38 1996 Ian Lance Taylor <ian@cygnus.com>
907
908 * Makefile.in (end.h): Use explicit ./ when running end.
909
910Sun May 19 21:05:31 1996 Rob Savoye <rob@chinadoll.cygnus.com>
911
912 * func.c(bfd_load): Don't try to print the filename if the pfbd is
913 NULL.
914 * interf.c(sim_load): Pass the whole string, not just the first
915 byte.
916
917Version 2.1 26-02-96
918--------------------
919
920* Fixed bug in "go" command.
921
922version 2.0 05-02-96
923--------------------
924
925* Fixed bug in interrupt force register (erc32.c).
926
927* Change file load function to use bfd_openr.
928
929* SIS should now be endian independent.
930
931version 1.8 24-11-95
932--------------------
933
934* Fixed FPU timing - some sequences of FPU instructions did not calculate
935 the resource dependencies right.
936
937* Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
938 but no FPU trap is generated.
939
940version 1.7.1 31-10-95
941--------------------
942
943* Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
944 the FPU stays in execute mode.
945
946* Corrected JMPL and RETT timing (these instructions takes two cycles).
947
948
949version 1.7 25-10-95
950--------------------
951
952* Interrupt during annuled instruction corrupted return address - fixed.
953
954
955version 1.6.2 25-10-95
956--------------------
957
958* Added -DFAST_UART to Makefile
959
960
961version 1.6.1 24-10-95
962--------------------
963
964* Fixed bug in STDFQ which caused bus error
965
966
967version 1.6 02-10-95
968--------------------
969
970* Modified srt0.s to include code that initiates registers in IU and FPU
971 and initializes the data segment. The simulator 'load' command does not
972 longer initialize the data segment!
973
974* Corrected MEC timer operation; scalers now divide the frequency by
975 (scaler_value + 1).
976
977* MEC breakpoints are not checked during store operation
978
979
980version 1.5 14-09-95
981--------------------
982
983* Fixed some bugs in the cycle counting for IU & FPU instructions.
984
985* Fixed bug that allowed an annuled instruction to cause memory exception.
986
987* The *ws parameter in mem.c should now contain the number of waitstates
988 required by the memory access (was total number of cycles).
989
990* The supplied srt0.s now clears the BSS (thanks Joel).
991
992version 1.4 22-08-95
993--------------------
994
995* Added a '-g' switch to enable/disable the GNU readline(), which cause
996some problems on solaris 2.x machines.
997
998* Enabled MEC watchpoint and breakpoint function to mem.c. Performance
999may suffer a bit ...
1000
1001NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1002
1003version 1.3 26-07-95
1004--------------------
1005
1006* Fixed bug in mulscc instruction (how could that ever have worked?)
1007
1008* Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1009
1010version 1.2 13-07-95
1011--------------------
1012
1013* Fixed bug in interrupt handling (wrong interrupt selected when more that
1014one interrupt pending)
1015
1016* Fixed updating of condition codes during logical instructions (carry and
1017overflow were not reset)
1018
1019* Fixed bug in WRTBR (tt field was wrongly over-written)
1020
1021version 1.1 07-07-95
1022--------------------
1023
1024* Fixed several bugs in the interrupt handler and callback routines.
