 154
 155 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 156
 157         * exec.c (dispatch_instruction):
 158         Correct the sense of the
 159                   if (!sparclite) {
 160                      sregs->trap = TRAP_UNIMP;
 161                      break;
 162                   }
 163         clause that has been pasted around: it's correct in the SCAN and
 164         DIVScc (divide step) cases (where it was probably originally
 165         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 166         ie. instructions only in the SPARC V8 or SPARClite 86x
 167         architectures.  It was also present when not required for SMUL,
 168         SMULcc, UMUL, UMULcc instructions that are present in all
 169         architectures.
 170
 171 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 172
 173         * interf.c (run_sim): Fix a bug in the main loop's handling of
 174         annulled delay slot instructions.  There is precedent for this
 175         change; the _other_ main loop in sis.c gets it right according to
 176         my reading of the code.
 177
 178         The bug is: if an interrupt happens when the next instruction
 179         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 180         with the current values of PC and NPC, so when the trap returns,
 181         the annulled instruction is indeed executed.  Another giveaway is
 182         that the annul flag is cleared in execute_trap(): the information
 183         is demonstrably discarded.
 184
 185         The solution is: perform annulling before looking for traps, in
 186         fact it's neater to do annulling, see if there's an interrupt and
 187         if not, do the instruction, then handle traps be they generated by
 188         interrupts pending or by the instruction we might just have done.
 189         That's what the sis.c one does.
 190
 191 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 192
 193         * sis.h: Add asr17 register for support of SparcLITE (at least the
 194         Hitachi ones I find before me)
 195
 196         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 197         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 198         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 199         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 200         (init_regs): Initialize y and asr17.
 201         NB: In instruction-set space, the Y register is asr0; the
 202         instructions have different names for human reasons only.
 203
 204         * sis.c:
 205         * interf.c: Set boolean mode variable dumbio if invoked with
 206         argument "-dumbio" and mention it of verbose.
 207         * erc32.c: if "dumbio" is set, do not assume that there is a
 208         terminal type device attached to stdin/stdout.  Do not set
 209         buffering or mess with tcsetattr or do any read operations in
 210         order to make UART interrupts; not input data is supported.
 211         This is necessary to allow the sim to be used within the eCos
 212         testing infrastructure where stdin/stdout are pipes to a TCL
 213         program; the sim hangs otherwise.
 214
 215 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>
 216
 217         * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.
 218
 219 Tue Jul  7 21:12:41 1998  Mark Alexander  <marka@cygnus.com>
 220
 221         * func.c (bfd_load): Add special handling of a.out executables.
 222
 223 Sat Jun 13 08:33:25 1998  Mark Alexander  <marka@cygnus.com>
 224
 225         * func.c (bfd_load): Print correct endianness.
 226         * interf.c (run_sim): Print debugging information if verbosity level
 227         is greater than 2.
 228         (sim_open): Repeated -v options now increment verbosity level.
 229         (sim_store_register): Handle little-endian case.
 230         (flush_window): Print debugging information if verbosity level
 231         is greater then 2.
 232
 233 Tue Jun  2 15:20:35 1998  Mark Alexander  <marka@cygnus.com>
 234
 235         * interf.c (sim_open): Use revamped memory_read, which makes
 236         byte-swapping unnecessary.  Add -sparclite-board option for
 237         emulating RAM found on typical SPARClite boards.  Print
 238         error message for unrecognized option.
 239         * erc32.c: Change RAM address and size from constants to variables,
 240         to allow emulation of SPARClite board RAM.
 241         (fetch_bytes, store_bytes): New helper functions for revamped
 242         mememory_read and memory_write.
 243         (memory_read, memory_write): Rewrite to store bytes in target
 244         byte order instead of storing words in host byte order; this
 245         greatly simplifies support of little-endian programs.
 246         (get_mem_ptr): Remove unnecessary byte parameter.
 247         (sis_memory_write, sis_memory_read): Store words in target
 248         byte order instead of host byte order.
 249         (byte_swap_words): Remove, no longer needed.
 250         * sis.h ((byte_swap_words): Remove declaration, no longer needed.
 251         (memory_read): Add new sz parameter.
 252         * sis.c (run_sim): Use revamped memory_read, which makes
 253         byte-swapping unnecessary.
 254         * exec.c (dispatch_instruction): Use revamped memory_read, which
 255         makes byte-swapping and double-word fetching unnecessary.
 256         * func.c (sparclite_board): Declare new variable.
 257         (get_regi): Handle little-endian data.
 258         (bfd_load): Recognize little-endian SPARClite as having
 259         little-endian data.
 260

 270         * exec.c (SDIV, SDIVCC, UDIV, UDIVCC): Define new opcodes.
 271         * (mul64): Simplify calculation of negative result.
 272         * (div64): New helper function for 64-bit division.
 273         * (dispatch_instruction): Add emulation of SDIV, SDIVCC, UDIV,
 274         and UDIVCC.
 275
 276 Wed May 13 14:59:54 1998  Mark Alexander  <marka@cygnus.com>
 277
 278         * erc32.c (close_port): Don't close stdin; it kills GDB.
 279         (byte_swap_words): New function.
 280         * sis.h: (byte_swap_words): Declare.
 281         * interf.c (run_sim): Always fetch instructions as big-endian.
 282         * sis.c (run_sim): Ditto.

 620         byte.
 621
 622 Version 2.1 26-02-96
 623 --------------------
 624
 625 * Fixed bug in "go" command.
 626
 627 version 2.0 05-02-96
 628 --------------------
 629
 630 * Fixed bug in interrupt force register (erc32.c).
 631
 632 * Change file load function to use bfd_openr.
 633
 634 * SIS should now be endian independent.
 635
 636 version 1.8 24-11-95
 637 --------------------
 638
 639 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 640   the resource dependencies right.
 641
 642 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 643   but no FPU trap is generated.
 644
 645 version 1.7.1 31-10-95
 646 --------------------
 647
 648 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 649   the FPU stays in execute mode.
 650
 651 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 652
 653
 654 version 1.7 25-10-95
 655 --------------------
 656
 657 * Interrupt during annuled instruction corrupted return address - fixed.
 658
 659
 660 version 1.6.2 25-10-95
 661 --------------------
 662
 663 * Added -DFAST_UART to Makefile
 664
 665
 666 version 1.6.1 24-10-95
 667 --------------------
 668
 669 * Fixed bug in STDFQ which caused bus error
 670
 671
 672 version 1.6 02-10-95
 673 --------------------
 674
 675 * Modified srt0.s to include code that initiates registers in IU and FPU
 676   and initializes the data segment. The simulator 'load' command does not
 677   longer initialize the data segment!
 678
 679 * Corrected MEC timer operation; scalers now divide the frequency by
 680   (scaler_value + 1).
 681
 682 * MEC breakpoints are not checked during store operation
 683
 684
 685 version 1.5 14-09-95
 686 --------------------
 687
 688 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 689
 690 * Fixed bug that allowed an annuled instruction to cause memory exception.
 691
 692 * The *ws parameter in mem.c should now contain the number of waitstates
 693   required by the memory access (was total number of cycles).
 694
 695 * The supplied srt0.s now clears the BSS (thanks Joel).
 696
 697 version 1.4 22-08-95
 698 --------------------
 699
 700 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 701 some problems on solaris 2.x machines.
 702
 703 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 704 may suffer a bit ...
 705
 706 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 707
 708 version 1.3 26-07-95
 709 --------------------
 710
 711 * Fixed bug in mulscc instruction (how could that ever have worked?)
 712
 713 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 714
 715 version 1.2 13-07-95
 716 --------------------
 717
 718 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 719 one interrupt pending)
 720
 721 * Fixed updating of condition codes during logical instructions (carry and
 722 overflow were not reset)
 723
 724 * Fixed bug in WRTBR (tt field was wrongly over-written)
 725
 726 version 1.1 07-07-95
 727 --------------------
 728
 729 * Fixed several bugs in the interrupt handler and callback routines.
 730 (reported by Paul Warren, Alsys)
