  37 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
  38
  39         * exec.c (dispatch_instruction):
  40         Correct the sense of the
  41                   if (!sparclite) {
  42                      sregs->trap = TRAP_UNIMP;
  43                      break;
  44                   }
  45         clause that has been pasted around: it's correct in the SCAN and
  46         DIVScc (divide step) cases (where it was probably originally
  47         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
  48         ie. instructions only in the SPARC V8 or SPARClite 86x
  49         architectures.  It was also present when not required for SMUL,
  50         SMULcc, UMUL, UMULcc instructions that are present in all
  51         architectures.
  52
  53 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
  54
  55         * interf.c (run_sim): Fix a bug in the main loop's handling of
  56         annulled delay slot instructions.  There is precedent for this
  57         change; the _other_ main loop in sis.c gets it right according to
  58         my reading of the code.
  59
  60         The bug is: if an interrupt happens when the next instruction
  61         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
  62         with the current values of PC and NPC, so when the trap returns,
  63         the annulled instruction is indeed executed.  Another giveaway is
  64         that the annul flag is cleared in execute_trap(): the information
  65         is demonstrably discarded.
  66
  67         The solution is: perform annulling before looking for traps, in
  68         fact it's neater to do annulling, see if there's an interrupt and
  69         if not, do the instruction, then handle traps be they generated by
  70         interrupts pending or by the instruction we might just have done.
  71         That's what the sis.c one does.
  72
  73 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
  74
  75         * sis.h: Add asr17 register for support of SparcLITE (at least the
  76         Hitachi ones I find before me)
  77
  78         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
  79         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
  80         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
  81         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
  82         (init_regs): Initialize y and asr17.
  83         NB: In instruction-set space, the Y register is asr0; the
  84         instructions have different names for human reasons only.
  85
  86         * sis.c:
  87         * interf.c: Set boolean mode variable dumbio if invoked with
  88         argument "-dumbio" and mention it of verbose.
  89         * erc32.c: if "dumbio" is set, do not assume that there is a
  90         terminal type device attached to stdin/stdout.  Do not set
  91         buffering or mess with tcsetattr or do any read operations in
  92         order to make UART interrupts; not input data is supported.
  93         This is necessary to allow the sim to be used within the eCos
  94         testing infrastructure where stdin/stdout are pipes to a TCL
  95         program; the sim hangs otherwise.
  96
  97 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>
  98
  99         * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.
 100
 101 Tue Jul  7 21:12:41 1998  Mark Alexander  <marka@cygnus.com>
 102
 103         * func.c (bfd_load): Add special handling of a.out executables.
 104
 105 Sat Jun 13 08:33:25 1998  Mark Alexander  <marka@cygnus.com>

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

 153         * (mul64): Simplify calculation of negative result.
 154         * (div64): New helper function for 64-bit division.
 155         * (dispatch_instruction): Add emulation of SDIV, SDIVCC, UDIV,
 156         and UDIVCC.
 157

 159
 160         * erc32.c (close_port): Don't close stdin; it kills GDB.

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

 502         byte.
 503
 504 Version 2.1 26-02-96
 505 --------------------
 506
 507 * Fixed bug in "go" command.
 508
 509 version 2.0 05-02-96
 510 --------------------
 511
 512 * Fixed bug in interrupt force register (erc32.c).
 513
 514 * Change file load function to use bfd_openr.
 515
 516 * SIS should now be endian independent.
 517
 518 version 1.8 24-11-95
 519 --------------------
 520
 521 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 522   the resource dependencies right.
 523
 524 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 525   but no FPU trap is generated.
 526
 527 version 1.7.1 31-10-95
 528 --------------------
 529
 530 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 531   the FPU stays in execute mode.
 532
 533 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 534
 535
 536 version 1.7 25-10-95
 537 --------------------
 538
 539 * Interrupt during annuled instruction corrupted return address - fixed.
 540
 541
 542 version 1.6.2 25-10-95
 543 --------------------
 544
 545 * Added -DFAST_UART to Makefile
 546
 547
 548 version 1.6.1 24-10-95
 549 --------------------
 550
 551 * Fixed bug in STDFQ which caused bus error
 552
 553
 554 version 1.6 02-10-95
 555 --------------------
 556
 557 * Modified srt0.s to include code that initiates registers in IU and FPU
 558   and initializes the data segment. The simulator 'load' command does not
 559   longer initialize the data segment!
 560
 561 * Corrected MEC timer operation; scalers now divide the frequency by
 562   (scaler_value + 1).
 563
 564 * MEC breakpoints are not checked during store operation
 565
 566
 567 version 1.5 14-09-95
 568 --------------------
 569
 570 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 571
 572 * Fixed bug that allowed an annuled instruction to cause memory exception.
 573
 574 * The *ws parameter in mem.c should now contain the number of waitstates
 575   required by the memory access (was total number of cycles).
 576
 577 * The supplied srt0.s now clears the BSS (thanks Joel).
 578
 579 version 1.4 22-08-95
 580 --------------------
 581
 582 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 583 some problems on solaris 2.x machines.
 584
 585 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 586 may suffer a bit ...
 587
 588 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 589
 590 version 1.3 26-07-95
 591 --------------------
 592
 593 * Fixed bug in mulscc instruction (how could that ever have worked?)
 594
 595 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 596
 597 version 1.2 13-07-95
 598 --------------------
 599
 600 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 601 one interrupt pending)
 602
 603 * Fixed updating of condition codes during logical instructions (carry and
 604 overflow were not reset)
 605
 606 * Fixed bug in WRTBR (tt field was wrongly over-written)
 607
 608 version 1.1 07-07-95
 609 --------------------
 610
 611 * Fixed several bugs in the interrupt handler and callback routines.
 612 (reported by Paul Warren, Alsys)
