 322         Correct the sense of the
 323                   if (!sparclite) {
 324                      sregs->trap = TRAP_UNIMP;
 325                      break;
 326                   }
 327         clause that has been pasted around: it's correct in the SCAN and
 328         DIVScc (divide step) cases (where it was probably originally
 329         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 330         ie. instructions only in the SPARC V8 or SPARClite 86x
 331         architectures.  It was also present when not required for SMUL,
 332         SMULcc, UMUL, UMULcc instructions that are present in all
 333         architectures.
 334
 335 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 336
 337         * interf.c (run_sim): Fix a bug in the main loop's handling of
 338         annulled delay slot instructions.  There is precedent for this
 339         change; the _other_ main loop in sis.c gets it right according to
 340         my reading of the code.
 341
 342         The bug is: if an interrupt happens when the next instruction
 343         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 344         with the current values of PC and NPC, so when the trap returns,
 345         the annulled instruction is indeed executed.  Another giveaway is
 346         that the annul flag is cleared in execute_trap(): the information
 347         is demonstrably discarded.
 348
 349         The solution is: perform annulling before looking for traps, in
 350         fact it's neater to do annulling, see if there's an interrupt and
 351         if not, do the instruction, then handle traps be they generated by
 352         interrupts pending or by the instruction we might just have done.
 353         That's what the sis.c one does.
 354
 355 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 356
 357         * sis.h: Add asr17 register for support of SparcLITE (at least the
 358         Hitachi ones I find before me)
 359
 360         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 361         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 362         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 363         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 364         (init_regs): Initialize y and asr17.
 365         NB: In instruction-set space, the Y register is asr0; the
 366         instructions have different names for human reasons only.
 367
 368         * sis.c:
 369         * interf.c: Set boolean mode variable dumbio if invoked with
 370         argument "-dumbio" and mention it of verbose.
 371         * erc32.c: if "dumbio" is set, do not assume that there is a
 372         terminal type device attached to stdin/stdout.  Do not set
 373         buffering or mess with tcsetattr or do any read operations in
 374         order to make UART interrupts; not input data is supported.
 375         This is necessary to allow the sim to be used within the eCos
 376         testing infrastructure where stdin/stdout are pipes to a TCL
 377         program; the sim hangs otherwise.

 751         * exec.c:  Add two new instructions: smul, and divscc.
 752         * interf.c (flush_windows):  New routine to flush the register
 753         windows out to the stack just before returning to GDB.  Makes
 754         backtraces work much better.

 756 Wed Jun 26 12:19:11 1996  Jason Molenda  (crash@godzilla.cygnus.co.jp)
 757
 758         * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir,
 759         INSTALL_PROGRAM, INSTALL_DATA): Use autoconf-set values.
 760         (docdir, oldincludedir): Removed.
 761         * configure.in (AC_PREREQ): autoconf 2.5 or higher.
 762         (AC_PROG_INSTALL): Added.
 763         * configure: Rebuilt.
 764
 765 Mon Jun 24 14:19:07 1996  Ian Lance Taylor  <ian@cygnus.com>
 766
 767         * configure.in: Call AC_PROG_CC before running configure.host.
 768         * configure: Rebuild with autoconf 2.10.

 770 Tue Jun  4 10:37:12 1996  Tom Tromey  <tromey@csk3.cygnus.com>
 771
 772         * Makefile.in (install): Don't check to see if tooldir exists.
 773         Make $(tooldir) and $(tooldir)/bin.
 774
 775 Mon Jun  3 12:33:38 1996  Ian Lance Taylor  <ian@cygnus.com>
 776
 777         * Makefile.in (end.h): Use explicit ./ when running end.
 778
 779 Sun May 19 21:05:31 1996  Rob Savoye  <rob@chinadoll.cygnus.com>
 780
 781         * func.c(bfd_load): Don't try to print the filename if the pfbd is
 782         NULL.
 783         * interf.c(sim_load): Pass the whole string, not just the first
 784         byte.
 785
 786 Version 2.1 26-02-96
 787 --------------------
 788
 789 * Fixed bug in "go" command.
 790
 791 version 2.0 05-02-96
 792 --------------------
 793
 794 * Fixed bug in interrupt force register (erc32.c).
 795
 796 * Change file load function to use bfd_openr.
 797
 798 * SIS should now be endian independent.
 799
 800 version 1.8 24-11-95
 801 --------------------
 802
 803 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 804   the resource dependencies right.
 805
 806 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 807   but no FPU trap is generated.
 808
 809 version 1.7.1 31-10-95
 810 --------------------
 811
 812 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 813   the FPU stays in execute mode.
 814
 815 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 816
 817
 818 version 1.7 25-10-95
 819 --------------------
 820
 821 * Interrupt during annuled instruction corrupted return address - fixed.
 822
 823
 824 version 1.6.2 25-10-95
 825 --------------------
 826
 827 * Added -DFAST_UART to Makefile
 828
 829
 830 version 1.6.1 24-10-95
 831 --------------------
 832
 833 * Fixed bug in STDFQ which caused bus error
 834
 835
 836 version 1.6 02-10-95
 837 --------------------
 838
 839 * Modified srt0.s to include code that initiates registers in IU and FPU
 840   and initializes the data segment. The simulator 'load' command does not
 841   longer initialize the data segment!
 842
 843 * Corrected MEC timer operation; scalers now divide the frequency by
 844   (scaler_value + 1).
 845
 846 * MEC breakpoints are not checked during store operation
 847
 848
 849 version 1.5 14-09-95
 850 --------------------
 851
 852 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 853
 854 * Fixed bug that allowed an annuled instruction to cause memory exception.
 855
 856 * The *ws parameter in mem.c should now contain the number of waitstates
 857   required by the memory access (was total number of cycles).
 858
 859 * The supplied srt0.s now clears the BSS (thanks Joel).
 860
 861 version 1.4 22-08-95
 862 --------------------
 863
 864 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 865 some problems on solaris 2.x machines.
 866
 867 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 868 may suffer a bit ...
 869
 870 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 871
 872 version 1.3 26-07-95
 873 --------------------
 874
 875 * Fixed bug in mulscc instruction (how could that ever have worked?)
 876
 877 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 878
 879 version 1.2 13-07-95
 880 --------------------
 881
 882 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 883 one interrupt pending)
 884
 885 * Fixed updating of condition codes during logical instructions (carry and
 886 overflow were not reset)
 887
 888 * Fixed bug in WRTBR (tt field was wrongly over-written)
 889
 890 version 1.1 07-07-95
 891 --------------------
 892
 893 * Fixed several bugs in the interrupt handler and callback routines.
 894 (reported by Paul Warren, Alsys)
