 305         Correct the sense of the
 306                   if (!sparclite) {
 307                      sregs->trap = TRAP_UNIMP;
 308                      break;
 309                   }
 310         clause that has been pasted around: it's correct in the SCAN and
 311         DIVScc (divide step) cases (where it was probably originally
 312         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 313         ie. instructions only in the SPARC V8 or SPARClite 86x
 314         architectures.  It was also present when not required for SMUL,
 315         SMULcc, UMUL, UMULcc instructions that are present in all
 316         architectures.
 317
 318 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 319
 320         * interf.c (run_sim): Fix a bug in the main loop's handling of
 321         annulled delay slot instructions.  There is precedent for this
 322         change; the _other_ main loop in sis.c gets it right according to
 323         my reading of the code.
 324
 325         The bug is: if an interrupt happens when the next instruction
 326         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 327         with the current values of PC and NPC, so when the trap returns,
 328         the annulled instruction is indeed executed.  Another giveaway is
 329         that the annul flag is cleared in execute_trap(): the information
 330         is demonstrably discarded.
 331
 332         The solution is: perform annulling before looking for traps, in
 333         fact it's neater to do annulling, see if there's an interrupt and
 334         if not, do the instruction, then handle traps be they generated by
 335         interrupts pending or by the instruction we might just have done.
 336         That's what the sis.c one does.
 337
 338 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 339
 340         * sis.h: Add asr17 register for support of SparcLITE (at least the
 341         Hitachi ones I find before me)
 342
 343         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 344         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 345         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 346         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 347         (init_regs): Initialize y and asr17.
 348         NB: In instruction-set space, the Y register is asr0; the
 349         instructions have different names for human reasons only.
 350
 351         * sis.c:
 352         * interf.c: Set boolean mode variable dumbio if invoked with
 353         argument "-dumbio" and mention it of verbose.
 354         * erc32.c: if "dumbio" is set, do not assume that there is a
 355         terminal type device attached to stdin/stdout.  Do not set
 356         buffering or mess with tcsetattr or do any read operations in
 357         order to make UART interrupts; not input data is supported.
 358         This is necessary to allow the sim to be used within the eCos
 359         testing infrastructure where stdin/stdout are pipes to a TCL
 360         program; the sim hangs otherwise.

 381
 382         * interf.c (sim_open): Use revamped memory_read, which makes
 383         byte-swapping unnecessary.  Add -sparclite-board option for
 384         emulating RAM found on typical SPARClite boards.  Print
 385         error message for unrecognized option.
 386         * erc32.c: Change RAM address and size from constants to variables,
 387         to allow emulation of SPARClite board RAM.
 388         (fetch_bytes, store_bytes): New helper functions for revamped
 389         mememory_read and memory_write.
 390         (memory_read, memory_write): Rewrite to store bytes in target
 391         byte order instead of storing words in host byte order; this
 392         greatly simplifies support of little-endian programs.
 393         (get_mem_ptr): Remove unnecessary byte parameter.
 394         (sis_memory_write, sis_memory_read): Store words in target
 395         byte order instead of host byte order.
 396         (byte_swap_words): Remove, no longer needed.

 751         * configure: Rebuild with autoconf 2.10.

 754
 755         * Makefile.in (install): Don't check to see if tooldir exists.
 756         Make $(tooldir) and $(tooldir)/bin.
 757
 758 Mon Jun  3 12:33:38 1996  Ian Lance Taylor  <ian@cygnus.com>
 759
 760         * Makefile.in (end.h): Use explicit ./ when running end.

 762 Sun May 19 21:05:31 1996  Rob Savoye  <rob@chinadoll.cygnus.com>
 763
 764         * func.c(bfd_load): Don't try to print the filename if the pfbd is
 765         NULL.
 766         * interf.c(sim_load): Pass the whole string, not just the first
 767         byte.
 768
 769 Version 2.1 26-02-96
 770 --------------------
 771
 772 * Fixed bug in "go" command.
 773
 774 version 2.0 05-02-96
 775 --------------------
 776
 777 * Fixed bug in interrupt force register (erc32.c).
 778
 779 * Change file load function to use bfd_openr.
 780
 781 * SIS should now be endian independent.
 782
 783 version 1.8 24-11-95
 784 --------------------
 785
 786 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 787   the resource dependencies right.
 788
 789 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 790   but no FPU trap is generated.
 791
 792 version 1.7.1 31-10-95
 793 --------------------
 794
 795 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 796   the FPU stays in execute mode.
 797
 798 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 799
 800
 801 version 1.7 25-10-95
 802 --------------------
 803
 804 * Interrupt during annuled instruction corrupted return address - fixed.
 805
 806
 807 version 1.6.2 25-10-95
 808 --------------------
 809
 810 * Added -DFAST_UART to Makefile
 811
 812
 813 version 1.6.1 24-10-95
 814 --------------------
 815
 816 * Fixed bug in STDFQ which caused bus error
 817
 818
 819 version 1.6 02-10-95
 820 --------------------
 821
 822 * Modified srt0.s to include code that initiates registers in IU and FPU
 823   and initializes the data segment. The simulator 'load' command does not
 824   longer initialize the data segment!
 825
 826 * Corrected MEC timer operation; scalers now divide the frequency by
 827   (scaler_value + 1).
 828
 829 * MEC breakpoints are not checked during store operation
 830
 831
 832 version 1.5 14-09-95
 833 --------------------
 834
 835 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 836
 837 * Fixed bug that allowed an annuled instruction to cause memory exception.
 838
 839 * The *ws parameter in mem.c should now contain the number of waitstates
 840   required by the memory access (was total number of cycles).
 841
 842 * The supplied srt0.s now clears the BSS (thanks Joel).
 843
 844 version 1.4 22-08-95
 845 --------------------
 846
 847 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 848 some problems on solaris 2.x machines.
 849
 850 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 851 may suffer a bit ...
 852
 853 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 854
 855 version 1.3 26-07-95
 856 --------------------
 857
 858 * Fixed bug in mulscc instruction (how could that ever have worked?)
 859
 860 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 861
 862 version 1.2 13-07-95
 863 --------------------
 864
 865 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 866 one interrupt pending)
 867
 868 * Fixed updating of condition codes during logical instructions (carry and
 869 overflow were not reset)
 870
 871 * Fixed bug in WRTBR (tt field was wrongly over-written)
 872
 873 version 1.1 07-07-95
 874 --------------------
 875
 876 * Fixed several bugs in the interrupt handler and callback routines.
