  81
  82 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
  83
  84         * exec.c (dispatch_instruction):
  85         Correct the sense of the
  86                   if (!sparclite) {
  87                      sregs->trap = TRAP_UNIMP;
  88                      break;
  89                   }
  90         clause that has been pasted around: it's correct in the SCAN and
  91         DIVScc (divide step) cases (where it was probably originally
  92         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
  93         ie. instructions only in the SPARC V8 or SPARClite 86x
  94         architectures.  It was also present when not required for SMUL,
  95         SMULcc, UMUL, UMULcc instructions that are present in all
  96         architectures.
  97
  98 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
  99
 100         * interf.c (run_sim): Fix a bug in the main loop's handling of
 101         annulled delay slot instructions.  There is precedent for this
 102         change; the _other_ main loop in sis.c gets it right according to
 103         my reading of the code.
 104
 105         The bug is: if an interrupt happens when the next instruction
 106         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 107         with the current values of PC and NPC, so when the trap returns,
 108         the annulled instruction is indeed executed.  Another giveaway is
 109         that the annul flag is cleared in execute_trap(): the information
 110         is demonstrably discarded.
 111
 112         The solution is: perform annulling before looking for traps, in
 113         fact it's neater to do annulling, see if there's an interrupt and
 114         if not, do the instruction, then handle traps be they generated by
 115         interrupts pending or by the instruction we might just have done.
 116         That's what the sis.c one does.
 117
 118 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 119
 120         * sis.h: Add asr17 register for support of SparcLITE (at least the
 121         Hitachi ones I find before me)
 122
 123         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 124         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 125         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 126         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 127         (init_regs): Initialize y and asr17.
 128         NB: In instruction-set space, the Y register is asr0; the
 129         instructions have different names for human reasons only.
 130
 131         * sis.c:
 132         * interf.c: Set boolean mode variable dumbio if invoked with
 133         argument "-dumbio" and mention it of verbose.
 134         * erc32.c: if "dumbio" is set, do not assume that there is a
 135         terminal type device attached to stdin/stdout.  Do not set
 136         buffering or mess with tcsetattr or do any read operations in
 137         order to make UART interrupts; not input data is supported.
 138         This is necessary to allow the sim to be used within the eCos
 139         testing infrastructure where stdin/stdout are pipes to a TCL
 140         program; the sim hangs otherwise.
 141
 142 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>
 143
 144         * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.
 145
 146 Tue Jul  7 21:12:41 1998  Mark Alexander  <marka@cygnus.com>
 147
 148         * func.c (bfd_load): Add special handling of a.out executables.
 149
 150 Sat Jun 13 08:33:25 1998  Mark Alexander  <marka@cygnus.com>

 153         * interf.c (run_sim): Print debugging information if verbosity level
 154         is greater than 2.
 155         (sim_open): Repeated -v options now increment verbosity level.
 156         (sim_store_register): Handle little-endian case.
 157         (flush_window): Print debugging information if verbosity level
 158         is greater then 2.
 159
 160 Tue Jun  2 15:20:35 1998  Mark Alexander  <marka@cygnus.com>
 161
 162         * interf.c (sim_open): Use revamped memory_read, which makes
 163         byte-swapping unnecessary.  Add -sparclite-board option for
 164         emulating RAM found on typical SPARClite boards.  Print
 165         error message for unrecognized option.
 166         * erc32.c: Change RAM address and size from constants to variables,
 167         to allow emulation of SPARClite board RAM.
 168         (fetch_bytes, store_bytes): New helper functions for revamped
 169         mememory_read and memory_write.
 170         (memory_read, memory_write): Rewrite to store bytes in target
 171         byte order instead of storing words in host byte order; this
 172         greatly simplifies support of little-endian programs.
 173         (get_mem_ptr): Remove unnecessary byte parameter.
 174         (sis_memory_write, sis_memory_read): Store words in target
 175         byte order instead of host byte order.
 176         (byte_swap_words): Remove, no longer needed.
 177         * sis.h ((byte_swap_words): Remove declaration, no longer needed.
 178         (memory_read): Add new sz parameter.
 179         * sis.c (run_sim): Use revamped memory_read, which makes
 180         byte-swapping unnecessary.
 181         * exec.c (dispatch_instruction): Use revamped memory_read, which
 182         makes byte-swapping and double-word fetching unnecessary.
 183         * func.c (sparclite_board): Declare new variable.
 184         (get_regi): Handle little-endian data.
 185         (bfd_load): Recognize little-endian SPARClite as having
 186         little-endian data.
 187

 198         * (mul64): Simplify calculation of negative result.
 199         * (div64): New helper function for 64-bit division.
 200         * (dispatch_instruction): Add emulation of SDIV, SDIVCC, UDIV,
 201         and UDIVCC.
 202

 207         * sis.h: (byte_swap_words): Declare.
 208         * interf.c (run_sim): Always fetch instructions as big-endian.

 547         byte.
 548
 549 Version 2.1 26-02-96
 550 --------------------
 551
 552 * Fixed bug in "go" command.
 553
 554 version 2.0 05-02-96
 555 --------------------
 556
 557 * Fixed bug in interrupt force register (erc32.c).
 558
 559 * Change file load function to use bfd_openr.
 560
 561 * SIS should now be endian independent.
 562
 563 version 1.8 24-11-95
 564 --------------------
 565
 566 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 567   the resource dependencies right.
 568
 569 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 570   but no FPU trap is generated.
 571
 572 version 1.7.1 31-10-95
 573 --------------------
 574
 575 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 576   the FPU stays in execute mode.
 577
 578 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 579
 580
 581 version 1.7 25-10-95
 582 --------------------
 583
 584 * Interrupt during annuled instruction corrupted return address - fixed.
 585
 586
 587 version 1.6.2 25-10-95
 588 --------------------
 589
 590 * Added -DFAST_UART to Makefile
 591
 592
 593 version 1.6.1 24-10-95
 594 --------------------
 595
 596 * Fixed bug in STDFQ which caused bus error
 597
 598
 599 version 1.6 02-10-95
 600 --------------------
 601
 602 * Modified srt0.s to include code that initiates registers in IU and FPU
 603   and initializes the data segment. The simulator 'load' command does not
 604   longer initialize the data segment!
 605
 606 * Corrected MEC timer operation; scalers now divide the frequency by
 607   (scaler_value + 1).
 608
 609 * MEC breakpoints are not checked during store operation
 610
 611
 612 version 1.5 14-09-95
 613 --------------------
 614
 615 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 616
 617 * Fixed bug that allowed an annuled instruction to cause memory exception.
 618
 619 * The *ws parameter in mem.c should now contain the number of waitstates
 620   required by the memory access (was total number of cycles).
 621
 622 * The supplied srt0.s now clears the BSS (thanks Joel).
 623
 624 version 1.4 22-08-95
 625 --------------------
 626
 627 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 628 some problems on solaris 2.x machines.
 629
 630 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 631 may suffer a bit ...
 632
 633 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 634
 635 version 1.3 26-07-95
 636 --------------------
 637
 638 * Fixed bug in mulscc instruction (how could that ever have worked?)
 639
 640 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 641
 642 version 1.2 13-07-95
 643 --------------------
 644
 645 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 646 one interrupt pending)
 647
 648 * Fixed updating of condition codes during logical instructions (carry and
 649 overflow were not reset)
 650
 651 * Fixed bug in WRTBR (tt field was wrongly over-written)
 652
 653 version 1.1 07-07-95
 654 --------------------
 655
 656 * Fixed several bugs in the interrupt handler and callback routines.
 657 (reported by Paul Warren, Alsys)
