 123
 124 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 125
 126         * exec.c (dispatch_instruction):
 127         Correct the sense of the
 128                   if (!sparclite) {
 129                      sregs->trap = TRAP_UNIMP;
 130                      break;
 131                   }
 132         clause that has been pasted around: it's correct in the SCAN and
 133         DIVScc (divide step) cases (where it was probably originally
 134         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 135         ie. instructions only in the SPARC V8 or SPARClite 86x
 136         architectures.  It was also present when not required for SMUL,
 137         SMULcc, UMUL, UMULcc instructions that are present in all
 138         architectures.
 139
 140 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 141
 142         * interf.c (run_sim): Fix a bug in the main loop's handling of
 143         annulled delay slot instructions.  There is precedent for this
 144         change; the _other_ main loop in sis.c gets it right according to
 145         my reading of the code.
 146
 147         The bug is: if an interrupt happens when the next instruction
 148         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 149         with the current values of PC and NPC, so when the trap returns,
 150         the annulled instruction is indeed executed.  Another giveaway is
 151         that the annul flag is cleared in execute_trap(): the information
 152         is demonstrably discarded.
 153
 154         The solution is: perform annulling before looking for traps, in
 155         fact it's neater to do annulling, see if there's an interrupt and
 156         if not, do the instruction, then handle traps be they generated by
 157         interrupts pending or by the instruction we might just have done.
 158         That's what the sis.c one does.
 159
 160 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 161
 162         * sis.h: Add asr17 register for support of SparcLITE (at least the
 163         Hitachi ones I find before me)
 164
 165         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 166         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 167         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 168         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 169         (init_regs): Initialize y and asr17.
 170         NB: In instruction-set space, the Y register is asr0; the
 171         instructions have different names for human reasons only.
 172
 173         * sis.c:
 174         * interf.c: Set boolean mode variable dumbio if invoked with
 175         argument "-dumbio" and mention it of verbose.
 176         * erc32.c: if "dumbio" is set, do not assume that there is a
 177         terminal type device attached to stdin/stdout.  Do not set
 178         buffering or mess with tcsetattr or do any read operations in
 179         order to make UART interrupts; not input data is supported.
 180         This is necessary to allow the sim to be used within the eCos
 181         testing infrastructure where stdin/stdout are pipes to a TCL
 182         program; the sim hangs otherwise.
 183
 184 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>
 185
 186         * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.
 187
 188 Tue Jul  7 21:12:41 1998  Mark Alexander  <marka@cygnus.com>
 189
 190         * func.c (bfd_load): Add special handling of a.out executables.
 191
 192 Sat Jun 13 08:33:25 1998  Mark Alexander  <marka@cygnus.com>
 193
 194         * func.c (bfd_load): Print correct endianness.
 195         * interf.c (run_sim): Print debugging information if verbosity level
 196         is greater than 2.
 197         (sim_open): Repeated -v options now increment verbosity level.
 198         (sim_store_register): Handle little-endian case.
 199         (flush_window): Print debugging information if verbosity level
 200         is greater then 2.
 201
 202 Tue Jun  2 15:20:35 1998  Mark Alexander  <marka@cygnus.com>
 203
 204         * interf.c (sim_open): Use revamped memory_read, which makes
 205         byte-swapping unnecessary.  Add -sparclite-board option for
 206         emulating RAM found on typical SPARClite boards.  Print
 207         error message for unrecognized option.
 208         * erc32.c: Change RAM address and size from constants to variables,
 209         to allow emulation of SPARClite board RAM.
 210         (fetch_bytes, store_bytes): New helper functions for revamped
 211         mememory_read and memory_write.
 212         (memory_read, memory_write): Rewrite to store bytes in target
 213         byte order instead of storing words in host byte order; this
 214         greatly simplifies support of little-endian programs.
 215         (get_mem_ptr): Remove unnecessary byte parameter.
 216         (sis_memory_write, sis_memory_read): Store words in target
 217         byte order instead of host byte order.
 218         (byte_swap_words): Remove, no longer needed.
 219         * sis.h ((byte_swap_words): Remove declaration, no longer needed.
 220         (memory_read): Add new sz parameter.
 221         * sis.c (run_sim): Use revamped memory_read, which makes
 222         byte-swapping unnecessary.
 223         * exec.c (dispatch_instruction): Use revamped memory_read, which
 224         makes byte-swapping and double-word fetching unnecessary.
 225         * func.c (sparclite_board): Declare new variable.
 226         (get_regi): Handle little-endian data.
 227         (bfd_load): Recognize little-endian SPARClite as having
 228         little-endian data.
 229
 230 Fri May 22 14:23:16 1998  Mark Alexander  <marka@cygnus.com>

 239         * exec.c (SDIV, SDIVCC, UDIV, UDIVCC): Define new opcodes.
 240         * (mul64): Simplify calculation of negative result.
 241         * (div64): New helper function for 64-bit division.
 242         * (dispatch_instruction): Add emulation of SDIV, SDIVCC, UDIV,
 243         and UDIVCC.
 244
 245 Wed May 13 14:59:54 1998  Mark Alexander  <marka@cygnus.com>
 246
 247         * erc32.c (close_port): Don't close stdin; it kills GDB.
 248         (byte_swap_words): New function.
 249         * sis.h: (byte_swap_words): Declare.
 250         * interf.c (run_sim): Always fetch instructions as big-endian.
 251         * sis.c (run_sim): Ditto.

 589         byte.
 590
 591 Version 2.1 26-02-96
 592 --------------------
 593
 594 * Fixed bug in "go" command.
 595
 596 version 2.0 05-02-96
 597 --------------------
 598
 599 * Fixed bug in interrupt force register (erc32.c).
 600
 601 * Change file load function to use bfd_openr.
 602
 603 * SIS should now be endian independent.
 604
 605 version 1.8 24-11-95
 606 --------------------
 607
 608 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 609   the resource dependencies right.
 610
 611 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 612   but no FPU trap is generated.
 613
 614 version 1.7.1 31-10-95
 615 --------------------
 616
 617 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 618   the FPU stays in execute mode.
 619
 620 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 621
 622
 623 version 1.7 25-10-95
 624 --------------------
 625
 626 * Interrupt during annuled instruction corrupted return address - fixed.
 627
 628
 629 version 1.6.2 25-10-95
 630 --------------------
 631
 632 * Added -DFAST_UART to Makefile
 633
 634
 635 version 1.6.1 24-10-95
 636 --------------------
 637
 638 * Fixed bug in STDFQ which caused bus error
 639
 640
 641 version 1.6 02-10-95
 642 --------------------
 643
 644 * Modified srt0.s to include code that initiates registers in IU and FPU
 645   and initializes the data segment. The simulator 'load' command does not
 646   longer initialize the data segment!
 647
 648 * Corrected MEC timer operation; scalers now divide the frequency by
 649   (scaler_value + 1).
 650
 651 * MEC breakpoints are not checked during store operation
 652
 653
 654 version 1.5 14-09-95
 655 --------------------
 656
 657 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 658
 659 * Fixed bug that allowed an annuled instruction to cause memory exception.
 660
 661 * The *ws parameter in mem.c should now contain the number of waitstates
 662   required by the memory access (was total number of cycles).
 663
 664 * The supplied srt0.s now clears the BSS (thanks Joel).
 665
 666 version 1.4 22-08-95
 667 --------------------
 668
 669 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 670 some problems on solaris 2.x machines.
 671
 672 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 673 may suffer a bit ...
 674
 675 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 676
 677 version 1.3 26-07-95
 678 --------------------
 679
 680 * Fixed bug in mulscc instruction (how could that ever have worked?)
 681
 682 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 683
 684 version 1.2 13-07-95
 685 --------------------
 686
 687 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 688 one interrupt pending)
 689
 690 * Fixed updating of condition codes during logical instructions (carry and
 691 overflow were not reset)
 692
 693 * Fixed bug in WRTBR (tt field was wrongly over-written)
 694
 695 version 1.1 07-07-95
 696 --------------------
 697
 698 * Fixed several bugs in the interrupt handler and callback routines.
 699 (reported by Paul Warren, Alsys)
