488 sregs->trap = TRAP_UNIMP;
72f4393d 489 break;
c906108c
SS
490 }
491 clause that has been pasted around: it's correct in the SCAN and
492 DIVScc (divide step) cases (where it was probably originally
493 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
494 ie. instructions only in the SPARC V8 or SPARClite 86x
495 architectures. It was also present when not required for SMUL,
496 SMULcc, UMUL, UMULcc instructions that are present in all
497 architectures.
498
4991999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
500
501 * interf.c (run_sim): Fix a bug in the main loop's handling of
502 annulled delay slot instructions. There is precedent for this
503 change; the _other_ main loop in sis.c gets it right according to
504 my reading of the code.
505
506 The bug is: if an interrupt happens when the next instruction
507 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
508 with the current values of PC and NPC, so when the trap returns,
509 the annulled instruction is indeed executed. Another giveaway is
510 that the annul flag is cleared in execute_trap(): the information
511 is demonstrably discarded.
512
513 The solution is: perform annulling before looking for traps, in
514 fact it's neater to do annulling, see if there's an interrupt and
515 if not, do the instruction, then handle traps be they generated by
516 interrupts pending or by the instruction we might just have done.
517 That's what the sis.c one does.
518
5191999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
520
521 * sis.h: Add asr17 register for support of SparcLITE (at least the
522 Hitachi ones I find before me)
523
524 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
525 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
526 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
527 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
528 (init_regs): Initialize y and asr17.
529 NB: In instruction-set space, the Y register is asr0; the
530 instructions have different names for human reasons only.
531
532 * sis.c:
533 * interf.c: Set boolean mode variable dumbio if invoked with
534 argument "-dumbio" and mention it of verbose.
535 * erc32.c: if "dumbio" is set, do not assume that there is a
536 terminal type device attached to stdin/stdout. Do not set
537 buffering or mess with tcsetattr or do any read operations in
538 order to make UART interrupts; not input data is supported.
539 This is necessary to allow the sim to be used within the eCos
540 testing infrastructure where stdin/stdout are pipes to a TCL
541 program; the sim hangs otherwise.

568 to allow emulation of SPARClite board RAM.
569 (fetch_bytes, store_bytes): New helper functions for revamped
570 mememory_read and memory_write.
571 (memory_read, memory_write): Rewrite to store bytes in target
572 byte order instead of storing words in host byte order; this
573 greatly simplifies support of little-endian programs.

575 (sis_memory_write, sis_memory_read): Store words in target

889Sun Sep 8 14:04:37 1996 Stu Grossman (grossman@critters.cygnus.com)
890
891 * erc32.c (port_init): Disable this for __GO32__ (got no pty's
892 there either...).
893
894Mon Aug 12 17:04:58 1996 Stu Grossman (grossman@critters.cygnus.com)
895
896 * erc32.c: Don't include sys/ioctl.h or sys/file.h. They aren't
897 necessary.
898 * (port_init): Don't even *try* to open pty's under _WIN32.
899 * Use SIM_ADDR, not caddr_t for declaring vars that hold addresses.
900 * float.c: Get rid of #warning. Makes Microsoft C barf.
901 * interf.c (sim_open): Cast fprintf to (fprintf_ftype) to fix
902 compiler warning.
903 * (sim_load sim_create_inferior sim_read): Use prototypes only in
904 decls, not defs.
905 * Get rid of enum sim_stop. It's defined in remote-sim.h.
906 * (sim_stop_reason): Define SIGTRAP if _WIN32.
907 * sis.h: Include ansidecl.h and remote-sim.h.

909Wed Jul 3 16:05:23 1996 Stu Grossman (grossman@critters.cygnus.com)
910
911 * erc32.c (mec_reset mec_read mec_write memory_read memory_write),
912 sis.h: Get rid of all uses of long long's.
913 * (close_port read_uart write_uart uarta_tx): Don't seg fault
914 when can't open pty's.
915 * exec.c: Add two new instructions: smul, and divscc.
916 * interf.c (flush_windows): New routine to flush the register
917 windows out to the stack just before returning to GDB. Makes
918 backtraces work much better.

922 * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir,
923 INSTALL_PROGRAM, INSTALL_DATA): Use autoconf-set values.
924 (docdir, oldincludedir): Removed.
925 * configure.in (AC_PREREQ): autoconf 2.5 or higher.
926 (AC_PROG_INSTALL): Added.
927 * configure: Rebuilt.

931 * configure.in: Call AC_PROG_CC before running configure.host.
932 * configure: Rebuild with autoconf 2.10.

934Tue Jun 4 10:37:12 1996 Tom Tromey <tromey@csk3.cygnus.com>
935
936 * Makefile.in (install): Don't check to see if tooldir exists.
937 Make $(tooldir) and $(tooldir)/bin.
938
939Mon Jun 3 12:33:38 1996 Ian Lance Taylor <ian@cygnus.com>
940
941 * Makefile.in (end.h): Use explicit ./ when running end.
942
943Sun May 19 21:05:31 1996 Rob Savoye <rob@chinadoll.cygnus.com>
944
945 * func.c(bfd_load): Don't try to print the filename if the pfbd is
946 NULL.
947 * interf.c(sim_load): Pass the whole string, not just the first
948 byte.
949
950Version 2.1 26-02-96
951--------------------
72f4393d 952
c906108c 953* Fixed bug in "go" command.
72f4393d 954
c906108c
SS
955version 2.0 05-02-96
956--------------------
957
958* Fixed bug in interrupt force register (erc32.c).
959
960* Change file load function to use bfd_openr.
961
962* SIS should now be endian independent.
963
964version 1.8 24-11-95
965--------------------
966
967* Fixed FPU timing - some sequences of FPU instructions did not calculate
968 the resource dependencies right.
969
970* Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
971 but no FPU trap is generated.
972
973version 1.7.1 31-10-95
974--------------------
975
976* Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
977 the FPU stays in execute mode.
978
979* Corrected JMPL and RETT timing (these instructions takes two cycles).
980
981
982version 1.7 25-10-95
983--------------------
984
985* Interrupt during annuled instruction corrupted return address - fixed.
986
987
988version 1.6.2 25-10-95
989--------------------
990
991* Added -DFAST_UART to Makefile

994version 1.6.1 24-10-95
995--------------------
72f4393d 996
c906108c
SS
997* Fixed bug in STDFQ which caused bus error
998
999
1000version 1.6 02-10-95
1001--------------------
72f4393d 1002
c906108c
SS
1003* Modified srt0.s to include code that initiates registers in IU and FPU
1004 and initializes the data segment. The simulator 'load' command does not
1005 longer initialize the data segment!
1006
72f4393d 1007* Corrected MEC timer operation; scalers now divide the frequency by
c906108c
SS
1008 (scaler_value + 1).
1009
1010* MEC breakpoints are not checked during store operation
1011
1012
1013version 1.5 14-09-95
1014--------------------
1015
1016* Fixed some bugs in the cycle counting for IU & FPU instructions.
1017
1018* Fixed bug that allowed an annuled instruction to cause memory exception.
1019
1020* The *ws parameter in mem.c should now contain the number of waitstates
1021 required by the memory access (was total number of cycles).
1022
1023* The supplied srt0.s now clears the BSS (thanks Joel).
1024
1025version 1.4 22-08-95
1026--------------------
1027
1028* Added a '-g' switch to enable/disable the GNU readline(), which cause
1029some problems on solaris 2.x machines.
1030
72f4393d 1031* Enabled MEC watchpoint and breakpoint function to mem.c. Performance
c906108c
SS
1032may suffer a bit ...
1033
1034NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1035
1036version 1.3 26-07-95
1037--------------------
1038
1039* Fixed bug in mulscc instruction (how could that ever have worked?)
1040
1041* Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1042
1043version 1.2 13-07-95
1044--------------------
1045
1046* Fixed bug in interrupt handling (wrong interrupt selected when more that
1047one interrupt pending)
1048
1049* Fixed updating of condition codes during logical instructions (carry and
1050overflow were not reset)
1051
1052* Fixed bug in WRTBR (tt field was wrongly over-written)
1053
1054version 1.1 07-07-95
1055--------------------
1056
1057* Fixed several bugs in the interrupt handler and callback routines.
