SS
469 Correct the sense of the
470 if (!sparclite) {
471 sregs->trap = TRAP_UNIMP;
72f4393d 472 break;
c906108c
SS
473 }
474 clause that has been pasted around: it's correct in the SCAN and
475 DIVScc (divide step) cases (where it was probably originally
476 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
477 ie. instructions only in the SPARC V8 or SPARClite 86x
478 architectures. It was also present when not required for SMUL,
479 SMULcc, UMUL, UMULcc instructions that are present in all
480 architectures.
481
4821999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
483
484 * interf.c (run_sim): Fix a bug in the main loop's handling of
485 annulled delay slot instructions. There is precedent for this
486 change; the _other_ main loop in sis.c gets it right according to
487 my reading of the code.
488
489 The bug is: if an interrupt happens when the next instruction
490 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
491 with the current values of PC and NPC, so when the trap returns,
492 the annulled instruction is indeed executed. Another giveaway is
493 that the annul flag is cleared in execute_trap(): the information
494 is demonstrably discarded.
495
496 The solution is: perform annulling before looking for traps, in
497 fact it's neater to do annulling, see if there's an interrupt and
498 if not, do the instruction, then handle traps be they generated by
499 interrupts pending or by the instruction we might just have done.
500 That's what the sis.c one does.
501
5021999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
503
504 * sis.h: Add asr17 register for support of SparcLITE (at least the
505 Hitachi ones I find before me)
506
507 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
508 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
509 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
510 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
511 (init_regs): Initialize y and asr17.
512 NB: In instruction-set space, the Y register is asr0; the
513 instructions have different names for human reasons only.
514
515 * sis.c:
516 * interf.c: Set boolean mode variable dumbio if invoked with
517 argument "-dumbio" and mention it of verbose.
518 * erc32.c: if "dumbio" is set, do not assume that there is a
519 terminal type device attached to stdin/stdout. Do not set
520 buffering or mess with tcsetattr or do any read operations in
521 order to make UART interrupts; not input data is supported.
522 This is necessary to allow the sim to be used within the eCos
523 testing infrastructure where stdin/stdout are pipes to a TCL
524 program; the sim hangs otherwise.

544Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com>

547 byte-swapping unnecessary. Add -sparclite-board option for
548 emulating RAM found on typical SPARClite boards. Print
549 error message for unrecognized option.
550 * erc32.c: Change RAM address and size from constants to variables,
551 to allow emulation of SPARClite board RAM.
552 (fetch_bytes, store_bytes): New helper functions for revamped
553 mememory_read and memory_write.
554 (memory_read, memory_write): Rewrite to store bytes in target
555 byte order instead of storing words in host byte order; this
556 greatly simplifies support of little-endian programs.
557 (get_mem_ptr): Remove unnecessary byte parameter.
558 (sis_memory_write, sis_memory_read): Store words in target

885 compiler warning.
886 * (sim_load sim_create_inferior sim_read): Use prototypes only in
887 decls, not defs.
888 * Get rid of enum sim_stop. It's defined in remote-sim.h.
889 * (sim_stop_reason): Define SIGTRAP if _WIN32.
890 * sis.h: Include ansidecl.h and remote-sim.h.

893
894 * erc32.c (mec_reset mec_read mec_write memory_read memory_write),
895 sis.h: Get rid of all uses of long long's.
896 * (close_port read_uart write_uart uarta_tx): Don't seg fault
897 when can't open pty's.
898 * exec.c: Add two new instructions: smul, and divscc.
899 * interf.c (flush_windows): New routine to flush the register
900 windows out to the stack just before returning to GDB. Makes
901 backtraces work much better.

905 * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir,
906 INSTALL_PROGRAM, INSTALL_DATA): Use autoconf-set values.
907 (docdir, oldincludedir): Removed.
908 * configure.in (AC_PREREQ): autoconf 2.5 or higher.
909 (AC_PROG_INSTALL): Added.

914 * configure.in: Call AC_PROG_CC before running configure.host.
915 * configure: Rebuild with autoconf 2.10.

917Tue Jun 4 10:37:12 1996 Tom Tromey <tromey@csk3.cygnus.com>
918
919 * Makefile.in (install): Don't check to see if tooldir exists.
920 Make $(tooldir) and $(tooldir)/bin.
921
922Mon Jun 3 12:33:38 1996 Ian Lance Taylor <ian@cygnus.com>
923
924 * Makefile.in (end.h): Use explicit ./ when running end.

926Sun May 19 21:05:31 1996 Rob Savoye <rob@chinadoll.cygnus.com>
927
928 * func.c(bfd_load): Don't try to print the filename if the pfbd is
929 NULL.
930 * interf.c(sim_load): Pass the whole string, not just the first
931 byte.
932
933Version 2.1 26-02-96
934--------------------
72f4393d 935
c906108c 936* Fixed bug in "go" command.
72f4393d 937
c906108c
SS
938version 2.0 05-02-96
939--------------------
940
941* Fixed bug in interrupt force register (erc32.c).
942
943* Change file load function to use bfd_openr.
944
945* SIS should now be endian independent.
946
947version 1.8 24-11-95
948--------------------
949
950* Fixed FPU timing - some sequences of FPU instructions did not calculate
951 the resource dependencies right.
952
953* Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
954 but no FPU trap is generated.
955
956version 1.7.1 31-10-95
957--------------------
958
959* Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
960 the FPU stays in execute mode.
961
962* Corrected JMPL and RETT timing (these instructions takes two cycles).
963
964
965version 1.7 25-10-95
966--------------------
967
968* Interrupt during annuled instruction corrupted return address - fixed.
969
970
971version 1.6.2 25-10-95
972--------------------
973
974* Added -DFAST_UART to Makefile

976
977version 1.6.1 24-10-95
978--------------------
72f4393d 979
c906108c
SS
980* Fixed bug in STDFQ which caused bus error
981
982
983version 1.6 02-10-95
984--------------------
72f4393d 985
c906108c
SS
986* Modified srt0.s to include code that initiates registers in IU and FPU
987 and initializes the data segment. The simulator 'load' command does not
988 longer initialize the data segment!
989
72f4393d 990* Corrected MEC timer operation; scalers now divide the frequency by
c906108c
SS
991 (scaler_value + 1).
992
993* MEC breakpoints are not checked during store operation
994
995
996version 1.5 14-09-95
997--------------------
998
999* Fixed some bugs in the cycle counting for IU & FPU instructions.
1000
1001* Fixed bug that allowed an annuled instruction to cause memory exception.
1002
1003* The *ws parameter in mem.c should now contain the number of waitstates
1004 required by the memory access (was total number of cycles).
1005
1006* The supplied srt0.s now clears the BSS (thanks Joel).
1007
1008version 1.4 22-08-95
1009--------------------
1010
1011* Added a '-g' switch to enable/disable the GNU readline(), which cause
1012some problems on solaris 2.x machines.
1013
72f4393d 1014* Enabled MEC watchpoint and breakpoint function to mem.c. Performance
c906108c
SS
1015may suffer a bit ...
1016
1017NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1018
1019version 1.3 26-07-95
1020--------------------
1021
1022* Fixed bug in mulscc instruction (how could that ever have worked?)
1023
1024* Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1025
1026version 1.2 13-07-95
1027--------------------
1028
1029* Fixed bug in interrupt handling (wrong interrupt selected when more that
1030one interrupt pending)
1031
1032* Fixed updating of condition codes during logical instructions (carry and
1033overflow were not reset)
1034
1035* Fixed bug in WRTBR (tt field was wrongly over-written)
1036
1037version 1.1 07-07-95
1038--------------------
1039
1040* Fixed several bugs in the interrupt handler and callback routines.
