  41 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
  42
  43         * exec.c (dispatch_instruction):
  44         Correct the sense of the
  45                   if (!sparclite) {
  46                      sregs->trap = TRAP_UNIMP;
  47                      break;
  48                   }
  49         clause that has been pasted around: it's correct in the SCAN and
  50         DIVScc (divide step) cases (where it was probably originally
  51         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
  52         ie. instructions only in the SPARC V8 or SPARClite 86x
  53         architectures.  It was also present when not required for SMUL,
  54         SMULcc, UMUL, UMULcc instructions that are present in all
  55         architectures.
  56
  57 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
  58
  59         * interf.c (run_sim): Fix a bug in the main loop's handling of
  60         annulled delay slot instructions.  There is precedent for this
  61         change; the _other_ main loop in sis.c gets it right according to
  62         my reading of the code.
  63
  64         The bug is: if an interrupt happens when the next instruction
  65         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
  66         with the current values of PC and NPC, so when the trap returns,
  67         the annulled instruction is indeed executed.  Another giveaway is
  68         that the annul flag is cleared in execute_trap(): the information
  69         is demonstrably discarded.
  70
  71         The solution is: perform annulling before looking for traps, in
  72         fact it's neater to do annulling, see if there's an interrupt and
  73         if not, do the instruction, then handle traps be they generated by
  74         interrupts pending or by the instruction we might just have done.
  75         That's what the sis.c one does.
  76
  77 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
  78
  79         * sis.h: Add asr17 register for support of SparcLITE (at least the
  80         Hitachi ones I find before me)
  81
  82         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
  83         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
  84         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
  85         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
  86         (init_regs): Initialize y and asr17.
  87         NB: In instruction-set space, the Y register is asr0; the
  88         instructions have different names for human reasons only.
  89
  90         * sis.c:
  91         * interf.c: Set boolean mode variable dumbio if invoked with
  92         argument "-dumbio" and mention it of verbose.
  93         * erc32.c: if "dumbio" is set, do not assume that there is a
  94         terminal type device attached to stdin/stdout.  Do not set
  95         buffering or mess with tcsetattr or do any read operations in
  96         order to make UART interrupts; not input data is supported.
  97         This is necessary to allow the sim to be used within the eCos
  98         testing infrastructure where stdin/stdout are pipes to a TCL
  99         program; the sim hangs otherwise.
 100
 101 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>
 102
 103         * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.
 104
 105 Tue Jul  7 21:12:41 1998  Mark Alexander  <marka@cygnus.com>
 106
 107         * func.c (bfd_load): Add special handling of a.out executables.
 108
 109 Sat Jun 13 08:33:25 1998  Mark Alexander  <marka@cygnus.com>

 112         * interf.c (run_sim): Print debugging information if verbosity level
 113         is greater than 2.
 114         (sim_open): Repeated -v options now increment verbosity level.
 115         (sim_store_register): Handle little-endian case.
 116         (flush_window): Print debugging information if verbosity level
 117         is greater then 2.
 118
 119 Tue Jun  2 15:20:35 1998  Mark Alexander  <marka@cygnus.com>
 120
 121         * interf.c (sim_open): Use revamped memory_read, which makes
 122         byte-swapping unnecessary.  Add -sparclite-board option for
 123         emulating RAM found on typical SPARClite boards.  Print
 124         error message for unrecognized option.
 125         * erc32.c: Change RAM address and size from constants to variables,
 126         to allow emulation of SPARClite board RAM.
 127         (fetch_bytes, store_bytes): New helper functions for revamped
 128         mememory_read and memory_write.
 129         (memory_read, memory_write): Rewrite to store bytes in target
 130         byte order instead of storing words in host byte order; this
 131         greatly simplifies support of little-endian programs.
 132         (get_mem_ptr): Remove unnecessary byte parameter.
 133         (sis_memory_write, sis_memory_read): Store words in target
 134         byte order instead of host byte order.
 135         (byte_swap_words): Remove, no longer needed.
 136         * sis.h ((byte_swap_words): Remove declaration, no longer needed.
 137         (memory_read): Add new sz parameter.
 138         * sis.c (run_sim): Use revamped memory_read, which makes
 139         byte-swapping unnecessary.
 140         * exec.c (dispatch_instruction): Use revamped memory_read, which
 141         makes byte-swapping and double-word fetching unnecessary.
 142         * func.c (sparclite_board): Declare new variable.
 143         (get_regi): Handle little-endian data.
 144         (bfd_load): Recognize little-endian SPARClite as having
 145         little-endian data.
 146

 157         * (mul64): Simplify calculation of negative result.
 158         * (div64): New helper function for 64-bit division.
 159         * (dispatch_instruction): Add emulation of SDIV, SDIVCC, UDIV,
 160         and UDIVCC.
 161

 163
 164         * erc32.c (close_port): Don't close stdin; it kills GDB.
 165         (byte_swap_words): New function.
 166         * sis.h: (byte_swap_words): Declare.
 167         * interf.c (run_sim): Always fetch instructions as big-endian.

 506         byte.
 507
 508 Version 2.1 26-02-96
 509 --------------------
 510
 511 * Fixed bug in "go" command.
 512
 513 version 2.0 05-02-96
 514 --------------------
 515
 516 * Fixed bug in interrupt force register (erc32.c).
 517
 518 * Change file load function to use bfd_openr.
 519
 520 * SIS should now be endian independent.
 521
 522 version 1.8 24-11-95
 523 --------------------
 524
 525 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 526   the resource dependencies right.
 527
 528 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 529   but no FPU trap is generated.
 530
 531 version 1.7.1 31-10-95
 532 --------------------
 533
 534 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 535   the FPU stays in execute mode.
 536
 537 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 538
 539
 540 version 1.7 25-10-95
 541 --------------------
 542
 543 * Interrupt during annuled instruction corrupted return address - fixed.
 544
 545
 546 version 1.6.2 25-10-95
 547 --------------------
 548
 549 * Added -DFAST_UART to Makefile
 550
 551
 552 version 1.6.1 24-10-95
 553 --------------------
 554
 555 * Fixed bug in STDFQ which caused bus error
 556
 557
 558 version 1.6 02-10-95
 559 --------------------
 560
 561 * Modified srt0.s to include code that initiates registers in IU and FPU
 562   and initializes the data segment. The simulator 'load' command does not
 563   longer initialize the data segment!
 564
 565 * Corrected MEC timer operation; scalers now divide the frequency by
 566   (scaler_value + 1).
 567
 568 * MEC breakpoints are not checked during store operation
 569
 570
 571 version 1.5 14-09-95
 572 --------------------
 573
 574 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 575
 576 * Fixed bug that allowed an annuled instruction to cause memory exception.
 577
 578 * The *ws parameter in mem.c should now contain the number of waitstates
 579   required by the memory access (was total number of cycles).
 580
 581 * The supplied srt0.s now clears the BSS (thanks Joel).
 582
 583 version 1.4 22-08-95
 584 --------------------
 585
 586 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 587 some problems on solaris 2.x machines.
 588
 589 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 590 may suffer a bit ...
 591
 592 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 593
 594 version 1.3 26-07-95
 595 --------------------
 596
 597 * Fixed bug in mulscc instruction (how could that ever have worked?)
 598
 599 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 600
 601 version 1.2 13-07-95
 602 --------------------
 603
 604 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 605 one interrupt pending)
 606
 607 * Fixed updating of condition codes during logical instructions (carry and
 608 overflow were not reset)
 609
 610 * Fixed bug in WRTBR (tt field was wrongly over-written)
 611
 612 version 1.1 07-07-95
 613 --------------------
 614
 615 * Fixed several bugs in the interrupt handler and callback routines.
 616 (reported by Paul Warren, Alsys)
