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

 754         * (close_port read_uart write_uart uarta_tx):  Don't seg fault
 755         when can't open pty's.
 756         * exec.c:  Add two new instructions: smul, and divscc.
 757         * interf.c (flush_windows):  New routine to flush the register
 758         windows out to the stack just before returning to GDB.  Makes
 759         backtraces work much better.

 762
 763         * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir,
 764         INSTALL_PROGRAM, INSTALL_DATA): Use autoconf-set values.
 765         (docdir, oldincludedir): Removed.
 766         * configure.in (AC_PREREQ): autoconf 2.5 or higher.
 767         (AC_PROG_INSTALL): Added.
 768         * configure: Rebuilt.

 770 Mon Jun 24 14:19:07 1996  Ian Lance Taylor  <ian@cygnus.com>
 771
 772         * configure.in: Call AC_PROG_CC before running configure.host.
 773         * configure: Rebuild with autoconf 2.10.

 775 Tue Jun  4 10:37:12 1996  Tom Tromey  <tromey@csk3.cygnus.com>
 776
 777         * Makefile.in (install): Don't check to see if tooldir exists.
 778         Make $(tooldir) and $(tooldir)/bin.
 779
 780 Mon Jun  3 12:33:38 1996  Ian Lance Taylor  <ian@cygnus.com>
 781
 782         * Makefile.in (end.h): Use explicit ./ when running end.
 783
 784 Sun May 19 21:05:31 1996  Rob Savoye  <rob@chinadoll.cygnus.com>
 785
 786         * func.c(bfd_load): Don't try to print the filename if the pfbd is
 787         NULL.
 788         * interf.c(sim_load): Pass the whole string, not just the first
 789         byte.
 790
 791 Version 2.1 26-02-96
 792 --------------------
 793
 794 * Fixed bug in "go" command.
 795
 796 version 2.0 05-02-96
 797 --------------------
 798
 799 * Fixed bug in interrupt force register (erc32.c).
 800
 801 * Change file load function to use bfd_openr.
 802
 803 * SIS should now be endian independent.
 804
 805 version 1.8 24-11-95
 806 --------------------
 807
 808 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 809   the resource dependencies right.
 810
 811 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 812   but no FPU trap is generated.
 813
 814 version 1.7.1 31-10-95
 815 --------------------
 816
 817 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 818   the FPU stays in execute mode.
 819
 820 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 821
 822
 823 version 1.7 25-10-95
 824 --------------------
 825
 826 * Interrupt during annuled instruction corrupted return address - fixed.
 827
 828
 829 version 1.6.2 25-10-95
 830 --------------------
 831
 832 * Added -DFAST_UART to Makefile
 833
 834
 835 version 1.6.1 24-10-95
 836 --------------------
 837
 838 * Fixed bug in STDFQ which caused bus error
 839
 840
 841 version 1.6 02-10-95
 842 --------------------
 843
 844 * Modified srt0.s to include code that initiates registers in IU and FPU
 845   and initializes the data segment. The simulator 'load' command does not
 846   longer initialize the data segment!
 847
 848 * Corrected MEC timer operation; scalers now divide the frequency by
 849   (scaler_value + 1).
 850
 851 * MEC breakpoints are not checked during store operation
 852
 853
 854 version 1.5 14-09-95
 855 --------------------
 856
 857 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 858
 859 * Fixed bug that allowed an annuled instruction to cause memory exception.
 860
 861 * The *ws parameter in mem.c should now contain the number of waitstates
 862   required by the memory access (was total number of cycles).
 863
 864 * The supplied srt0.s now clears the BSS (thanks Joel).
 865
 866 version 1.4 22-08-95
 867 --------------------
 868
 869 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 870 some problems on solaris 2.x machines.
 871
 872 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 873 may suffer a bit ...
 874
 875 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 876
 877 version 1.3 26-07-95
 878 --------------------
 879
 880 * Fixed bug in mulscc instruction (how could that ever have worked?)
 881
 882 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 883
 884 version 1.2 13-07-95
 885 --------------------
 886
 887 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 888 one interrupt pending)
 889
 890 * Fixed updating of condition codes during logical instructions (carry and
 891 overflow were not reset)
 892
 893 * Fixed bug in WRTBR (tt field was wrongly over-written)
 894
 895 version 1.1 07-07-95
 896 --------------------
 897
 898 * Fixed several bugs in the interrupt handler and callback routines.
 899 (reported by Paul Warren, Alsys)
