 134
 135 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 136
 137         * exec.c (dispatch_instruction):
 138         Correct the sense of the
 139                   if (!sparclite) {
 140                      sregs->trap = TRAP_UNIMP;
 141                      break;
 142                   }
 143         clause that has been pasted around: it's correct in the SCAN and
 144         DIVScc (divide step) cases (where it was probably originally
 145         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 146         ie. instructions only in the SPARC V8 or SPARClite 86x
 147         architectures.  It was also present when not required for SMUL,
 148         SMULcc, UMUL, UMULcc instructions that are present in all
 149         architectures.
 150
 151 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 152
 153         * interf.c (run_sim): Fix a bug in the main loop's handling of
 154         annulled delay slot instructions.  There is precedent for this
 155         change; the _other_ main loop in sis.c gets it right according to
 156         my reading of the code.
 157
 158         The bug is: if an interrupt happens when the next instruction
 159         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 160         with the current values of PC and NPC, so when the trap returns,
 161         the annulled instruction is indeed executed.  Another giveaway is
 162         that the annul flag is cleared in execute_trap(): the information
 163         is demonstrably discarded.
 164
 165         The solution is: perform annulling before looking for traps, in
 166         fact it's neater to do annulling, see if there's an interrupt and
 167         if not, do the instruction, then handle traps be they generated by
 168         interrupts pending or by the instruction we might just have done.
 169         That's what the sis.c one does.
 170
 171 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 172
 173         * sis.h: Add asr17 register for support of SparcLITE (at least the
 174         Hitachi ones I find before me)
 175
 176         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 177         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 178         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 179         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 180         (init_regs): Initialize y and asr17.
 181         NB: In instruction-set space, the Y register is asr0; the
 182         instructions have different names for human reasons only.
 183
 184         * sis.c:
 185         * interf.c: Set boolean mode variable dumbio if invoked with
 186         argument "-dumbio" and mention it of verbose.
 187         * erc32.c: if "dumbio" is set, do not assume that there is a
 188         terminal type device attached to stdin/stdout.  Do not set
 189         buffering or mess with tcsetattr or do any read operations in
 190         order to make UART interrupts; not input data is supported.
 191         This is necessary to allow the sim to be used within the eCos
 192         testing infrastructure where stdin/stdout are pipes to a TCL
 193         program; the sim hangs otherwise.
 194
 195 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>
 196
 197         * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.
 198
 199 Tue Jul  7 21:12:41 1998  Mark Alexander  <marka@cygnus.com>
 200
 201         * func.c (bfd_load): Add special handling of a.out executables.
 202
 203 Sat Jun 13 08:33:25 1998  Mark Alexander  <marka@cygnus.com>
 204

 206         * interf.c (run_sim): Print debugging information if verbosity level
 207         is greater than 2.
 208         (sim_open): Repeated -v options now increment verbosity level.
 209         (sim_store_register): Handle little-endian case.
 210         (flush_window): Print debugging information if verbosity level
 211         is greater then 2.
 212
 213 Tue Jun  2 15:20:35 1998  Mark Alexander  <marka@cygnus.com>
 214
 215         * interf.c (sim_open): Use revamped memory_read, which makes
 216         byte-swapping unnecessary.  Add -sparclite-board option for
 217         emulating RAM found on typical SPARClite boards.  Print
 218         error message for unrecognized option.
 219         * erc32.c: Change RAM address and size from constants to variables,
 220         to allow emulation of SPARClite board RAM.
 221         (fetch_bytes, store_bytes): New helper functions for revamped
 222         mememory_read and memory_write.
 223         (memory_read, memory_write): Rewrite to store bytes in target
 224         byte order instead of storing words in host byte order; this
 225         greatly simplifies support of little-endian programs.
 226         (get_mem_ptr): Remove unnecessary byte parameter.
 227         (sis_memory_write, sis_memory_read): Store words in target
 228         byte order instead of host byte order.
 229         (byte_swap_words): Remove, no longer needed.
 230         * sis.h ((byte_swap_words): Remove declaration, no longer needed.
 231         (memory_read): Add new sz parameter.
 232         * sis.c (run_sim): Use revamped memory_read, which makes
 233         byte-swapping unnecessary.
 234         * exec.c (dispatch_instruction): Use revamped memory_read, which
 235         makes byte-swapping and double-word fetching unnecessary.
 236         * func.c (sparclite_board): Declare new variable.
 237         (get_regi): Handle little-endian data.
 238         (bfd_load): Recognize little-endian SPARClite as having
 239         little-endian data.
 240
 241 Fri May 22 14:23:16 1998  Mark Alexander  <marka@cygnus.com>

 250         * exec.c (SDIV, SDIVCC, UDIV, UDIVCC): Define new opcodes.
 251         * (mul64): Simplify calculation of negative result.
 252         * (div64): New helper function for 64-bit division.
 253         * (dispatch_instruction): Add emulation of SDIV, SDIVCC, UDIV,
 254         and UDIVCC.
 255
 256 Wed May 13 14:59:54 1998  Mark Alexander  <marka@cygnus.com>
 257
 258         * erc32.c (close_port): Don't close stdin; it kills GDB.
 259         (byte_swap_words): New function.
 260         * sis.h: (byte_swap_words): Declare.
 261         * interf.c (run_sim): Always fetch instructions as big-endian.
 262         * sis.c (run_sim): Ditto.

 600         byte.
 601
 602 Version 2.1 26-02-96
 603 --------------------
 604
 605 * Fixed bug in "go" command.
 606
 607 version 2.0 05-02-96
 608 --------------------
 609
 610 * Fixed bug in interrupt force register (erc32.c).
 611
 612 * Change file load function to use bfd_openr.
 613
 614 * SIS should now be endian independent.
 615
 616 version 1.8 24-11-95
 617 --------------------
 618
 619 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 620   the resource dependencies right.
 621
 622 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 623   but no FPU trap is generated.
 624
 625 version 1.7.1 31-10-95
 626 --------------------
 627
 628 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 629   the FPU stays in execute mode.
 630
 631 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 632
 633
 634 version 1.7 25-10-95
 635 --------------------
 636
 637 * Interrupt during annuled instruction corrupted return address - fixed.
 638
 639
 640 version 1.6.2 25-10-95
 641 --------------------
 642
 643 * Added -DFAST_UART to Makefile
 644
 645
 646 version 1.6.1 24-10-95
 647 --------------------
 648
 649 * Fixed bug in STDFQ which caused bus error
 650
 651
 652 version 1.6 02-10-95
 653 --------------------
 654
 655 * Modified srt0.s to include code that initiates registers in IU and FPU
 656   and initializes the data segment. The simulator 'load' command does not
 657   longer initialize the data segment!
 658
 659 * Corrected MEC timer operation; scalers now divide the frequency by
 660   (scaler_value + 1).
 661
 662 * MEC breakpoints are not checked during store operation
 663
 664
 665 version 1.5 14-09-95
 666 --------------------
 667
 668 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 669
 670 * Fixed bug that allowed an annuled instruction to cause memory exception.
 671
 672 * The *ws parameter in mem.c should now contain the number of waitstates
 673   required by the memory access (was total number of cycles).
 674
 675 * The supplied srt0.s now clears the BSS (thanks Joel).
 676
 677 version 1.4 22-08-95
 678 --------------------
 679
 680 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 681 some problems on solaris 2.x machines.
 682
 683 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 684 may suffer a bit ...
 685
 686 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 687
 688 version 1.3 26-07-95
 689 --------------------
 690
 691 * Fixed bug in mulscc instruction (how could that ever have worked?)
 692
 693 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 694
 695 version 1.2 13-07-95
 696 --------------------
 697
 698 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 699 one interrupt pending)
 700
 701 * Fixed updating of condition codes during logical instructions (carry and
 702 overflow were not reset)
 703
 704 * Fixed bug in WRTBR (tt field was wrongly over-written)
 705
 706 version 1.1 07-07-95
 707 --------------------
 708
 709 * Fixed several bugs in the interrupt handler and callback routines.
 710 (reported by Paul Warren, Alsys)
