 317         Correct the sense of the
 318                   if (!sparclite) {
 319                      sregs->trap = TRAP_UNIMP;
 320                      break;
 321                   }
 322         clause that has been pasted around: it's correct in the SCAN and
 323         DIVScc (divide step) cases (where it was probably originally
 324         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 325         ie. instructions only in the SPARC V8 or SPARClite 86x
 326         architectures.  It was also present when not required for SMUL,
 327         SMULcc, UMUL, UMULcc instructions that are present in all
 328         architectures.
 329
 330 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 331
 332         * interf.c (run_sim): Fix a bug in the main loop's handling of
 333         annulled delay slot instructions.  There is precedent for this
 334         change; the _other_ main loop in sis.c gets it right according to
 335         my reading of the code.
 336
 337         The bug is: if an interrupt happens when the next instruction
 338         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 339         with the current values of PC and NPC, so when the trap returns,
 340         the annulled instruction is indeed executed.  Another giveaway is
 341         that the annul flag is cleared in execute_trap(): the information
 342         is demonstrably discarded.
 343
 344         The solution is: perform annulling before looking for traps, in
 345         fact it's neater to do annulling, see if there's an interrupt and
 346         if not, do the instruction, then handle traps be they generated by
 347         interrupts pending or by the instruction we might just have done.
 348         That's what the sis.c one does.
 349
 350 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 351
 352         * sis.h: Add asr17 register for support of SparcLITE (at least the
 353         Hitachi ones I find before me)
 354
 355         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 356         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 357         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 358         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 359         (init_regs): Initialize y and asr17.
 360         NB: In instruction-set space, the Y register is asr0; the
 361         instructions have different names for human reasons only.
 362
 363         * sis.c:
 364         * interf.c: Set boolean mode variable dumbio if invoked with
 365         argument "-dumbio" and mention it of verbose.
 366         * erc32.c: if "dumbio" is set, do not assume that there is a
 367         terminal type device attached to stdin/stdout.  Do not set
 368         buffering or mess with tcsetattr or do any read operations in
 369         order to make UART interrupts; not input data is supported.
 370         This is necessary to allow the sim to be used within the eCos
 371         testing infrastructure where stdin/stdout are pipes to a TCL
 372         program; the sim hangs otherwise.

 393
 394         * interf.c (sim_open): Use revamped memory_read, which makes
 395         byte-swapping unnecessary.  Add -sparclite-board option for
 396         emulating RAM found on typical SPARClite boards.  Print
 397         error message for unrecognized option.
 398         * erc32.c: Change RAM address and size from constants to variables,

 753         * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir,
 754         INSTALL_PROGRAM, INSTALL_DATA): Use autoconf-set values.
 755         (docdir, oldincludedir): Removed.
 756         * configure.in (AC_PREREQ): autoconf 2.5 or higher.
 757         (AC_PROG_INSTALL): Added.
 758         * configure: Rebuilt.
 759
 760 Mon Jun 24 14:19:07 1996  Ian Lance Taylor  <ian@cygnus.com>
 761
 762         * configure.in: Call AC_PROG_CC before running configure.host.
 763         * configure: Rebuild with autoconf 2.10.

 765 Tue Jun  4 10:37:12 1996  Tom Tromey  <tromey@csk3.cygnus.com>
 766
 767         * Makefile.in (install): Don't check to see if tooldir exists.
 768         Make $(tooldir) and $(tooldir)/bin.
 769
 770 Mon Jun  3 12:33:38 1996  Ian Lance Taylor  <ian@cygnus.com>
 771
 772         * Makefile.in (end.h): Use explicit ./ when running end.

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