 158
 159 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 160
 161         * exec.c (dispatch_instruction):
 162         Correct the sense of the
 163                   if (!sparclite) {
 164                      sregs->trap = TRAP_UNIMP;
 165                      break;
 166                   }
 167         clause that has been pasted around: it's correct in the SCAN and
 168         DIVScc (divide step) cases (where it was probably originally
 169         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 170         ie. instructions only in the SPARC V8 or SPARClite 86x
 171         architectures.  It was also present when not required for SMUL,
 172         SMULcc, UMUL, UMULcc instructions that are present in all
 173         architectures.
 174
 175 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 176
 177         * interf.c (run_sim): Fix a bug in the main loop's handling of
 178         annulled delay slot instructions.  There is precedent for this
 179         change; the _other_ main loop in sis.c gets it right according to
 180         my reading of the code.
 181
 182         The bug is: if an interrupt happens when the next instruction
 183         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 184         with the current values of PC and NPC, so when the trap returns,
 185         the annulled instruction is indeed executed.  Another giveaway is
 186         that the annul flag is cleared in execute_trap(): the information
 187         is demonstrably discarded.
 188
 189         The solution is: perform annulling before looking for traps, in
 190         fact it's neater to do annulling, see if there's an interrupt and
 191         if not, do the instruction, then handle traps be they generated by
 192         interrupts pending or by the instruction we might just have done.
 193         That's what the sis.c one does.
 194
 195 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 196
 197         * sis.h: Add asr17 register for support of SparcLITE (at least the
 198         Hitachi ones I find before me)
 199
 200         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 201         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 202         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 203         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 204         (init_regs): Initialize y and asr17.
 205         NB: In instruction-set space, the Y register is asr0; the
 206         instructions have different names for human reasons only.
 207
 208         * sis.c:
 209         * interf.c: Set boolean mode variable dumbio if invoked with
 210         argument "-dumbio" and mention it of verbose.
 211         * erc32.c: if "dumbio" is set, do not assume that there is a
 212         terminal type device attached to stdin/stdout.  Do not set
 213         buffering or mess with tcsetattr or do any read operations in
 214         order to make UART interrupts; not input data is supported.
 215         This is necessary to allow the sim to be used within the eCos
 216         testing infrastructure where stdin/stdout are pipes to a TCL
 217         program; the sim hangs otherwise.
 218
 219 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>
 220
 221         * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.
 222
 223 Tue Jul  7 21:12:41 1998  Mark Alexander  <marka@cygnus.com>
 224
 225         * func.c (bfd_load): Add special handling of a.out executables.
 226
 227 Sat Jun 13 08:33:25 1998  Mark Alexander  <marka@cygnus.com>
 228
 229         * func.c (bfd_load): Print correct endianness.
 230         * interf.c (run_sim): Print debugging information if verbosity level
 231         is greater than 2.
 232         (sim_open): Repeated -v options now increment verbosity level.
 233         (sim_store_register): Handle little-endian case.
 234         (flush_window): Print debugging information if verbosity level
 235         is greater then 2.
 236
 237 Tue Jun  2 15:20:35 1998  Mark Alexander  <marka@cygnus.com>
 238
 239         * interf.c (sim_open): Use revamped memory_read, which makes
 240         byte-swapping unnecessary.  Add -sparclite-board option for
 241         emulating RAM found on typical SPARClite boards.  Print
 242         error message for unrecognized option.
 243         * erc32.c: Change RAM address and size from constants to variables,
 244         to allow emulation of SPARClite board RAM.
 245         (fetch_bytes, store_bytes): New helper functions for revamped
 246         mememory_read and memory_write.
 247         (memory_read, memory_write): Rewrite to store bytes in target
 248         byte order instead of storing words in host byte order; this
 249         greatly simplifies support of little-endian programs.
 250         (get_mem_ptr): Remove unnecessary byte parameter.
 251         (sis_memory_write, sis_memory_read): Store words in target
 252         byte order instead of host byte order.
 253         (byte_swap_words): Remove, no longer needed.
 254         * sis.h ((byte_swap_words): Remove declaration, no longer needed.
 255         (memory_read): Add new sz parameter.
 256         * sis.c (run_sim): Use revamped memory_read, which makes
 257         byte-swapping unnecessary.
 258         * exec.c (dispatch_instruction): Use revamped memory_read, which
 259         makes byte-swapping and double-word fetching unnecessary.
 260         * func.c (sparclite_board): Declare new variable.
 261         (get_regi): Handle little-endian data.
 262         (bfd_load): Recognize little-endian SPARClite as having
 263         little-endian data.
 264

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

 624         byte.
 625
 626 Version 2.1 26-02-96
 627 --------------------
 628
 629 * Fixed bug in "go" command.
 630
 631 version 2.0 05-02-96
 632 --------------------
 633
 634 * Fixed bug in interrupt force register (erc32.c).
 635
 636 * Change file load function to use bfd_openr.
 637
 638 * SIS should now be endian independent.
 639
 640 version 1.8 24-11-95
 641 --------------------
 642
 643 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 644   the resource dependencies right.
 645
 646 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 647   but no FPU trap is generated.
 648
 649 version 1.7.1 31-10-95
 650 --------------------
 651
 652 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 653   the FPU stays in execute mode.
 654
 655 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 656
 657
 658 version 1.7 25-10-95
 659 --------------------
 660
 661 * Interrupt during annuled instruction corrupted return address - fixed.
 662
 663
 664 version 1.6.2 25-10-95
 665 --------------------
 666
 667 * Added -DFAST_UART to Makefile
 668
 669
 670 version 1.6.1 24-10-95
 671 --------------------
 672
 673 * Fixed bug in STDFQ which caused bus error
 674
 675
 676 version 1.6 02-10-95
 677 --------------------
 678
 679 * Modified srt0.s to include code that initiates registers in IU and FPU
 680   and initializes the data segment. The simulator 'load' command does not
 681   longer initialize the data segment!
 682
 683 * Corrected MEC timer operation; scalers now divide the frequency by
 684   (scaler_value + 1).
 685
 686 * MEC breakpoints are not checked during store operation
 687
 688
 689 version 1.5 14-09-95
 690 --------------------
 691
 692 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 693
 694 * Fixed bug that allowed an annuled instruction to cause memory exception.
 695
 696 * The *ws parameter in mem.c should now contain the number of waitstates
 697   required by the memory access (was total number of cycles).
 698
 699 * The supplied srt0.s now clears the BSS (thanks Joel).
 700
 701 version 1.4 22-08-95
 702 --------------------
 703
 704 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 705 some problems on solaris 2.x machines.
 706
 707 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 708 may suffer a bit ...
 709
 710 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 711
 712 version 1.3 26-07-95
 713 --------------------
 714
 715 * Fixed bug in mulscc instruction (how could that ever have worked?)
 716
 717 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 718
 719 version 1.2 13-07-95
 720 --------------------
 721
 722 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 723 one interrupt pending)
 724
 725 * Fixed updating of condition codes during logical instructions (carry and
 726 overflow were not reset)
 727
 728 * Fixed bug in WRTBR (tt field was wrongly over-written)
 729
 730 version 1.1 07-07-95
 731 --------------------
 732
 733 * Fixed several bugs in the interrupt handler and callback routines.
 734 (reported by Paul Warren, Alsys)
