  45
  46 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
  47
  48         * exec.c (dispatch_instruction):
  49         Correct the sense of the
  50                   if (!sparclite) {
  51                      sregs->trap = TRAP_UNIMP;
  52                      break;
  53                   }
  54         clause that has been pasted around: it's correct in the SCAN and
  55         DIVScc (divide step) cases (where it was probably originally
  56         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
  57         ie. instructions only in the SPARC V8 or SPARClite 86x
  58         architectures.  It was also present when not required for SMUL,
  59         SMULcc, UMUL, UMULcc instructions that are present in all
  60         architectures.
  61
  62 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
  63
  64         * interf.c (run_sim): Fix a bug in the main loop's handling of
  65         annulled delay slot instructions.  There is precedent for this
  66         change; the _other_ main loop in sis.c gets it right according to
  67         my reading of the code.
  68
  69         The bug is: if an interrupt happens when the next instruction
  70         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
  71         with the current values of PC and NPC, so when the trap returns,
  72         the annulled instruction is indeed executed.  Another giveaway is
  73         that the annul flag is cleared in execute_trap(): the information
  74         is demonstrably discarded.
  75
  76         The solution is: perform annulling before looking for traps, in
  77         fact it's neater to do annulling, see if there's an interrupt and
  78         if not, do the instruction, then handle traps be they generated by
  79         interrupts pending or by the instruction we might just have done.
  80         That's what the sis.c one does.
  81
  82 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
  83
  84         * sis.h: Add asr17 register for support of SparcLITE (at least the
  85         Hitachi ones I find before me)
  86
  87         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
  88         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
  89         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
  90         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
  91         (init_regs): Initialize y and asr17.
  92         NB: In instruction-set space, the Y register is asr0; the
  93         instructions have different names for human reasons only.
  94
  95         * sis.c:
  96         * interf.c: Set boolean mode variable dumbio if invoked with
  97         argument "-dumbio" and mention it of verbose.
  98         * erc32.c: if "dumbio" is set, do not assume that there is a
  99         terminal type device attached to stdin/stdout.  Do not set
 100         buffering or mess with tcsetattr or do any read operations in
 101         order to make UART interrupts; not input data is supported.
 102         This is necessary to allow the sim to be used within the eCos
 103         testing infrastructure where stdin/stdout are pipes to a TCL
 104         program; the sim hangs otherwise.
 105
 106 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>
 107
 108         * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.
 109
 110 Tue Jul  7 21:12:41 1998  Mark Alexander  <marka@cygnus.com>
 111
 112         * func.c (bfd_load): Add special handling of a.out executables.
 113
 114 Sat Jun 13 08:33:25 1998  Mark Alexander  <marka@cygnus.com>
 115
 116         * func.c (bfd_load): Print correct endianness.
 117         * interf.c (run_sim): Print debugging information if verbosity level
 118         is greater than 2.
 119         (sim_open): Repeated -v options now increment verbosity level.
 120         (sim_store_register): Handle little-endian case.
 121         (flush_window): Print debugging information if verbosity level
 122         is greater then 2.
 123
 124 Tue Jun  2 15:20:35 1998  Mark Alexander  <marka@cygnus.com>
 125
 126         * interf.c (sim_open): Use revamped memory_read, which makes
 127         byte-swapping unnecessary.  Add -sparclite-board option for
 128         emulating RAM found on typical SPARClite boards.  Print
 129         error message for unrecognized option.
 130         * erc32.c: Change RAM address and size from constants to variables,
 131         to allow emulation of SPARClite board RAM.
 132         (fetch_bytes, store_bytes): New helper functions for revamped
 133         mememory_read and memory_write.
 134         (memory_read, memory_write): Rewrite to store bytes in target
 135         byte order instead of storing words in host byte order; this
 136         greatly simplifies support of little-endian programs.
 137         (get_mem_ptr): Remove unnecessary byte parameter.
 138         (sis_memory_write, sis_memory_read): Store words in target
 139         byte order instead of host byte order.
 140         (byte_swap_words): Remove, no longer needed.
 141         * sis.h ((byte_swap_words): Remove declaration, no longer needed.
 142         (memory_read): Add new sz parameter.
 143         * sis.c (run_sim): Use revamped memory_read, which makes
 144         byte-swapping unnecessary.
 145         * exec.c (dispatch_instruction): Use revamped memory_read, which
 146         makes byte-swapping and double-word fetching unnecessary.
 147         * func.c (sparclite_board): Declare new variable.
 148         (get_regi): Handle little-endian data.
 149         (bfd_load): Recognize little-endian SPARClite as having
 150         little-endian data.
 151

 162         * (mul64): Simplify calculation of negative result.
 163         * (div64): New helper function for 64-bit division.
 164         * (dispatch_instruction): Add emulation of SDIV, SDIVCC, UDIV,
 165         and UDIVCC.
 166
 167 Wed May 13 14:59:54 1998  Mark Alexander  <marka@cygnus.com>
 168
 169         * erc32.c (close_port): Don't close stdin; it kills GDB.
 170         (byte_swap_words): New function.
 171         * sis.h: (byte_swap_words): Declare.
 172         * interf.c (run_sim): Always fetch instructions as big-endian.

 511         byte.
 512
 513 Version 2.1 26-02-96
 514 --------------------
 515
 516 * Fixed bug in "go" command.
 517
 518 version 2.0 05-02-96
 519 --------------------
 520
 521 * Fixed bug in interrupt force register (erc32.c).
 522
 523 * Change file load function to use bfd_openr.
 524
 525 * SIS should now be endian independent.
 526
 527 version 1.8 24-11-95
 528 --------------------
 529
 530 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 531   the resource dependencies right.
 532
 533 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 534   but no FPU trap is generated.
 535
 536 version 1.7.1 31-10-95
 537 --------------------
 538
 539 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 540   the FPU stays in execute mode.
 541
 542 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 543
 544
 545 version 1.7 25-10-95
 546 --------------------
 547
 548 * Interrupt during annuled instruction corrupted return address - fixed.
 549
 550
 551 version 1.6.2 25-10-95
 552 --------------------
 553
 554 * Added -DFAST_UART to Makefile
 555
 556
 557 version 1.6.1 24-10-95
 558 --------------------
 559
 560 * Fixed bug in STDFQ which caused bus error
 561
 562
 563 version 1.6 02-10-95
 564 --------------------
 565
 566 * Modified srt0.s to include code that initiates registers in IU and FPU
 567   and initializes the data segment. The simulator 'load' command does not
 568   longer initialize the data segment!
 569
 570 * Corrected MEC timer operation; scalers now divide the frequency by
 571   (scaler_value + 1).
 572
 573 * MEC breakpoints are not checked during store operation
 574
 575
 576 version 1.5 14-09-95
 577 --------------------
 578
 579 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 580
 581 * Fixed bug that allowed an annuled instruction to cause memory exception.
 582
 583 * The *ws parameter in mem.c should now contain the number of waitstates
 584   required by the memory access (was total number of cycles).
 585
 586 * The supplied srt0.s now clears the BSS (thanks Joel).
 587
 588 version 1.4 22-08-95
 589 --------------------
 590
 591 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 592 some problems on solaris 2.x machines.
 593
 594 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 595 may suffer a bit ...
 596
 597 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 598
 599 version 1.3 26-07-95
 600 --------------------
 601
 602 * Fixed bug in mulscc instruction (how could that ever have worked?)
 603
 604 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 605
 606 version 1.2 13-07-95
 607 --------------------
 608
 609 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 610 one interrupt pending)
 611
 612 * Fixed updating of condition codes during logical instructions (carry and
 613 overflow were not reset)
 614
 615 * Fixed bug in WRTBR (tt field was wrongly over-written)
 616
 617 version 1.1 07-07-95
 618 --------------------
 619
 620 * Fixed several bugs in the interrupt handler and callback routines.
 621 (reported by Paul Warren, Alsys)
