  89
  90 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
  91
  92         * exec.c (dispatch_instruction):
  93         Correct the sense of the
  94                   if (!sparclite) {
  95                      sregs->trap = TRAP_UNIMP;
  96                      break;
  97                   }
  98         clause that has been pasted around: it's correct in the SCAN and
  99         DIVScc (divide step) cases (where it was probably originally
 100         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 101         ie. instructions only in the SPARC V8 or SPARClite 86x
 102         architectures.  It was also present when not required for SMUL,
 103         SMULcc, UMUL, UMULcc instructions that are present in all
 104         architectures.
 105
 106 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 107
 108         * interf.c (run_sim): Fix a bug in the main loop's handling of
 109         annulled delay slot instructions.  There is precedent for this
 110         change; the _other_ main loop in sis.c gets it right according to
 111         my reading of the code.
 112
 113         The bug is: if an interrupt happens when the next instruction
 114         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 115         with the current values of PC and NPC, so when the trap returns,
 116         the annulled instruction is indeed executed.  Another giveaway is
 117         that the annul flag is cleared in execute_trap(): the information
 118         is demonstrably discarded.
 119
 120         The solution is: perform annulling before looking for traps, in
 121         fact it's neater to do annulling, see if there's an interrupt and
 122         if not, do the instruction, then handle traps be they generated by
 123         interrupts pending or by the instruction we might just have done.
 124         That's what the sis.c one does.
 125
 126 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 127
 128         * sis.h: Add asr17 register for support of SparcLITE (at least the
 129         Hitachi ones I find before me)
 130
 131         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 132         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 133         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 134         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 135         (init_regs): Initialize y and asr17.
 136         NB: In instruction-set space, the Y register is asr0; the
 137         instructions have different names for human reasons only.
 138
 139         * sis.c:
 140         * interf.c: Set boolean mode variable dumbio if invoked with
 141         argument "-dumbio" and mention it of verbose.
 142         * erc32.c: if "dumbio" is set, do not assume that there is a
 143         terminal type device attached to stdin/stdout.  Do not set
 144         buffering or mess with tcsetattr or do any read operations in
 145         order to make UART interrupts; not input data is supported.
 146         This is necessary to allow the sim to be used within the eCos
 147         testing infrastructure where stdin/stdout are pipes to a TCL
 148         program; the sim hangs otherwise.
 149
 150 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>
 151
 152         * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.
 153

 157
 158 Sat Jun 13 08:33:25 1998  Mark Alexander  <marka@cygnus.com>

 161         * interf.c (run_sim): Print debugging information if verbosity level
 162         is greater than 2.
 163         (sim_open): Repeated -v options now increment verbosity level.
 164         (sim_store_register): Handle little-endian case.
 165         (flush_window): Print debugging information if verbosity level
 166         is greater then 2.
 167
 168 Tue Jun  2 15:20:35 1998  Mark Alexander  <marka@cygnus.com>
 169
 170         * interf.c (sim_open): Use revamped memory_read, which makes
 171         byte-swapping unnecessary.  Add -sparclite-board option for
 172         emulating RAM found on typical SPARClite boards.  Print
 173         error message for unrecognized option.
 174         * erc32.c: Change RAM address and size from constants to variables,
 175         to allow emulation of SPARClite board RAM.
 176         (fetch_bytes, store_bytes): New helper functions for revamped
 177         mememory_read and memory_write.
 178         (memory_read, memory_write): Rewrite to store bytes in target
 179         byte order instead of storing words in host byte order; this
 180         greatly simplifies support of little-endian programs.
 181         (get_mem_ptr): Remove unnecessary byte parameter.
 182         (sis_memory_write, sis_memory_read): Store words in target
 183         byte order instead of host byte order.
 184         (byte_swap_words): Remove, no longer needed.
 185         * sis.h ((byte_swap_words): Remove declaration, no longer needed.
 186         (memory_read): Add new sz parameter.
 187         * sis.c (run_sim): Use revamped memory_read, which makes
 188         byte-swapping unnecessary.
 189         * exec.c (dispatch_instruction): Use revamped memory_read, which
 190         makes byte-swapping and double-word fetching unnecessary.
 191         * func.c (sparclite_board): Declare new variable.
 192         (get_regi): Handle little-endian data.
 193         (bfd_load): Recognize little-endian SPARClite as having
 194         little-endian data.
 195

 206         * (mul64): Simplify calculation of negative result.
 207         * (div64): New helper function for 64-bit division.
 208         * (dispatch_instruction): Add emulation of SDIV, SDIVCC, UDIV,
 209         and UDIVCC.
 210

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

 555         byte.
 556
 557 Version 2.1 26-02-96
 558 --------------------
 559
 560 * Fixed bug in "go" command.
 561
 562 version 2.0 05-02-96
 563 --------------------
 564
 565 * Fixed bug in interrupt force register (erc32.c).
 566
 567 * Change file load function to use bfd_openr.
 568
 569 * SIS should now be endian independent.
 570
 571 version 1.8 24-11-95
 572 --------------------
 573
 574 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 575   the resource dependencies right.
 576
 577 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 578   but no FPU trap is generated.
 579
 580 version 1.7.1 31-10-95
 581 --------------------
 582
 583 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 584   the FPU stays in execute mode.
 585
 586 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 587
 588
 589 version 1.7 25-10-95
 590 --------------------
 591
 592 * Interrupt during annuled instruction corrupted return address - fixed.
 593
 594
 595 version 1.6.2 25-10-95
 596 --------------------
 597
 598 * Added -DFAST_UART to Makefile
 599
 600
 601 version 1.6.1 24-10-95
 602 --------------------
 603
 604 * Fixed bug in STDFQ which caused bus error
 605
 606
 607 version 1.6 02-10-95
 608 --------------------
 609
 610 * Modified srt0.s to include code that initiates registers in IU and FPU
 611   and initializes the data segment. The simulator 'load' command does not
 612   longer initialize the data segment!
 613
 614 * Corrected MEC timer operation; scalers now divide the frequency by
 615   (scaler_value + 1).
 616
 617 * MEC breakpoints are not checked during store operation
 618
 619
 620 version 1.5 14-09-95
 621 --------------------
 622
 623 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 624
 625 * Fixed bug that allowed an annuled instruction to cause memory exception.
 626
 627 * The *ws parameter in mem.c should now contain the number of waitstates
 628   required by the memory access (was total number of cycles).
 629
 630 * The supplied srt0.s now clears the BSS (thanks Joel).
 631
 632 version 1.4 22-08-95
 633 --------------------
 634
 635 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 636 some problems on solaris 2.x machines.
 637
 638 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 639 may suffer a bit ...
 640
 641 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 642
 643 version 1.3 26-07-95
 644 --------------------
 645
 646 * Fixed bug in mulscc instruction (how could that ever have worked?)
 647
 648 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 649
 650 version 1.2 13-07-95
 651 --------------------
 652
 653 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 654 one interrupt pending)
 655
 656 * Fixed updating of condition codes during logical instructions (carry and
 657 overflow were not reset)
 658
 659 * Fixed bug in WRTBR (tt field was wrongly over-written)
 660
 661 version 1.1 07-07-95
 662 --------------------
 663
 664 * Fixed several bugs in the interrupt handler and callback routines.
 665 (reported by Paul Warren, Alsys)
