  55 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
  56
  57         * exec.c (dispatch_instruction):
  58         Correct the sense of the
  59                   if (!sparclite) {
  60                      sregs->trap = TRAP_UNIMP;
  61                      break;
  62                   }
  63         clause that has been pasted around: it's correct in the SCAN and
  64         DIVScc (divide step) cases (where it was probably originally
  65         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
  66         ie. instructions only in the SPARC V8 or SPARClite 86x
  67         architectures.  It was also present when not required for SMUL,
  68         SMULcc, UMUL, UMULcc instructions that are present in all
  69         architectures.
  70
  71 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
  72
  73         * interf.c (run_sim): Fix a bug in the main loop's handling of
  74         annulled delay slot instructions.  There is precedent for this
  75         change; the _other_ main loop in sis.c gets it right according to
  76         my reading of the code.
  77
  78         The bug is: if an interrupt happens when the next instruction
  79         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
  80         with the current values of PC and NPC, so when the trap returns,
  81         the annulled instruction is indeed executed.  Another giveaway is
  82         that the annul flag is cleared in execute_trap(): the information
  83         is demonstrably discarded.
  84
  85         The solution is: perform annulling before looking for traps, in
  86         fact it's neater to do annulling, see if there's an interrupt and
  87         if not, do the instruction, then handle traps be they generated by
  88         interrupts pending or by the instruction we might just have done.
  89         That's what the sis.c one does.
  90
  91 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
  92
  93         * sis.h: Add asr17 register for support of SparcLITE (at least the
  94         Hitachi ones I find before me)
  95
  96         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
  97         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
  98         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
  99         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 100         (init_regs): Initialize y and asr17.
 101         NB: In instruction-set space, the Y register is asr0; the
 102         instructions have different names for human reasons only.
 103
 104         * sis.c:
 105         * interf.c: Set boolean mode variable dumbio if invoked with
 106         argument "-dumbio" and mention it of verbose.
 107         * erc32.c: if "dumbio" is set, do not assume that there is a
 108         terminal type device attached to stdin/stdout.  Do not set
 109         buffering or mess with tcsetattr or do any read operations in
 110         order to make UART interrupts; not input data is supported.
 111         This is necessary to allow the sim to be used within the eCos
 112         testing infrastructure where stdin/stdout are pipes to a TCL
 113         program; the sim hangs otherwise.
 114
 115 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>
 116
 117         * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.
 118

 122
 123 Sat Jun 13 08:33:25 1998  Mark Alexander  <marka@cygnus.com>
 124

 126         * interf.c (run_sim): Print debugging information if verbosity level
 127         is greater than 2.
 128         (sim_open): Repeated -v options now increment verbosity level.
 129         (sim_store_register): Handle little-endian case.
 130         (flush_window): Print debugging information if verbosity level
 131         is greater then 2.
 132
 133 Tue Jun  2 15:20:35 1998  Mark Alexander  <marka@cygnus.com>
 134
 135         * interf.c (sim_open): Use revamped memory_read, which makes
 136         byte-swapping unnecessary.  Add -sparclite-board option for
 137         emulating RAM found on typical SPARClite boards.  Print
 138         error message for unrecognized option.
 139         * erc32.c: Change RAM address and size from constants to variables,
 140         to allow emulation of SPARClite board RAM.
 141         (fetch_bytes, store_bytes): New helper functions for revamped
 142         mememory_read and memory_write.
 143         (memory_read, memory_write): Rewrite to store bytes in target
 144         byte order instead of storing words in host byte order; this
 145         greatly simplifies support of little-endian programs.
 146         (get_mem_ptr): Remove unnecessary byte parameter.
 147         (sis_memory_write, sis_memory_read): Store words in target
 148         byte order instead of host byte order.
 149         (byte_swap_words): Remove, no longer needed.
 150         * sis.h ((byte_swap_words): Remove declaration, no longer needed.
 151         (memory_read): Add new sz parameter.
 152         * sis.c (run_sim): Use revamped memory_read, which makes
 153         byte-swapping unnecessary.
 154         * exec.c (dispatch_instruction): Use revamped memory_read, which
 155         makes byte-swapping and double-word fetching unnecessary.
 156         * func.c (sparclite_board): Declare new variable.
 157         (get_regi): Handle little-endian data.
 158         (bfd_load): Recognize little-endian SPARClite as having
 159         little-endian data.
 160

 170         * exec.c (SDIV, SDIVCC, UDIV, UDIVCC): Define new opcodes.
 171         * (mul64): Simplify calculation of negative result.
 172         * (div64): New helper function for 64-bit division.
 173         * (dispatch_instruction): Add emulation of SDIV, SDIVCC, UDIV,
 174         and UDIVCC.
 175

 177
 178         * erc32.c (close_port): Don't close stdin; it kills GDB.
 179         (byte_swap_words): New function.
 180         * sis.h: (byte_swap_words): Declare.
 181         * interf.c (run_sim): Always fetch instructions as big-endian.

 520         byte.
 521
 522 Version 2.1 26-02-96
 523 --------------------
 524
 525 * Fixed bug in "go" command.
 526
 527 version 2.0 05-02-96
 528 --------------------
 529
 530 * Fixed bug in interrupt force register (erc32.c).
 531
 532 * Change file load function to use bfd_openr.
 533
 534 * SIS should now be endian independent.
 535
 536 version 1.8 24-11-95
 537 --------------------
 538
 539 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 540   the resource dependencies right.
 541
 542 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 543   but no FPU trap is generated.
 544
 545 version 1.7.1 31-10-95
 546 --------------------
 547
 548 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 549   the FPU stays in execute mode.
 550
 551 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 552
 553
 554 version 1.7 25-10-95
 555 --------------------
 556
 557 * Interrupt during annuled instruction corrupted return address - fixed.
 558
 559
 560 version 1.6.2 25-10-95
 561 --------------------
 562
 563 * Added -DFAST_UART to Makefile
 564
 565
 566 version 1.6.1 24-10-95
 567 --------------------
 568
 569 * Fixed bug in STDFQ which caused bus error
 570
 571
 572 version 1.6 02-10-95
 573 --------------------
 574
 575 * Modified srt0.s to include code that initiates registers in IU and FPU
 576   and initializes the data segment. The simulator 'load' command does not
 577   longer initialize the data segment!
 578
 579 * Corrected MEC timer operation; scalers now divide the frequency by
 580   (scaler_value + 1).
 581
 582 * MEC breakpoints are not checked during store operation
 583
 584
 585 version 1.5 14-09-95
 586 --------------------
 587
 588 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 589
 590 * Fixed bug that allowed an annuled instruction to cause memory exception.
 591
 592 * The *ws parameter in mem.c should now contain the number of waitstates
 593   required by the memory access (was total number of cycles).
 594
 595 * The supplied srt0.s now clears the BSS (thanks Joel).
 596
 597 version 1.4 22-08-95
 598 --------------------
 599
 600 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 601 some problems on solaris 2.x machines.
 602
 603 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 604 may suffer a bit ...
 605
 606 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 607
 608 version 1.3 26-07-95
 609 --------------------
 610
 611 * Fixed bug in mulscc instruction (how could that ever have worked?)
 612
 613 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 614
 615 version 1.2 13-07-95
 616 --------------------
 617
 618 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 619 one interrupt pending)
 620
 621 * Fixed updating of condition codes during logical instructions (carry and
 622 overflow were not reset)
 623
 624 * Fixed bug in WRTBR (tt field was wrongly over-written)
 625
 626 version 1.1 07-07-95
 627 --------------------
 628
 629 * Fixed several bugs in the interrupt handler and callback routines.
 630 (reported by Paul Warren, Alsys)
