 102
 103 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 104
 105         * exec.c (dispatch_instruction):
 106         Correct the sense of the
 107                   if (!sparclite) {
 108                      sregs->trap = TRAP_UNIMP;
 109                      break;
 110                   }
 111         clause that has been pasted around: it's correct in the SCAN and
 112         DIVScc (divide step) cases (where it was probably originally
 113         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 114         ie. instructions only in the SPARC V8 or SPARClite 86x
 115         architectures.  It was also present when not required for SMUL,
 116         SMULcc, UMUL, UMULcc instructions that are present in all
 117         architectures.
 118
 119 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 120
 121         * interf.c (run_sim): Fix a bug in the main loop's handling of
 122         annulled delay slot instructions.  There is precedent for this
 123         change; the _other_ main loop in sis.c gets it right according to
 124         my reading of the code.
 125
 126         The bug is: if an interrupt happens when the next instruction
 127         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 128         with the current values of PC and NPC, so when the trap returns,
 129         the annulled instruction is indeed executed.  Another giveaway is
 130         that the annul flag is cleared in execute_trap(): the information
 131         is demonstrably discarded.
 132
 133         The solution is: perform annulling before looking for traps, in
 134         fact it's neater to do annulling, see if there's an interrupt and
 135         if not, do the instruction, then handle traps be they generated by
 136         interrupts pending or by the instruction we might just have done.
 137         That's what the sis.c one does.
 138
 139 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 140
 141         * sis.h: Add asr17 register for support of SparcLITE (at least the
 142         Hitachi ones I find before me)
 143
 144         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 145         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 146         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 147         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 148         (init_regs): Initialize y and asr17.
 149         NB: In instruction-set space, the Y register is asr0; the
 150         instructions have different names for human reasons only.
 151
 152         * sis.c:
 153         * interf.c: Set boolean mode variable dumbio if invoked with
 154         argument "-dumbio" and mention it of verbose.
 155         * erc32.c: if "dumbio" is set, do not assume that there is a
 156         terminal type device attached to stdin/stdout.  Do not set
 157         buffering or mess with tcsetattr or do any read operations in
 158         order to make UART interrupts; not input data is supported.
 159         This is necessary to allow the sim to be used within the eCos
 160         testing infrastructure where stdin/stdout are pipes to a TCL
 161         program; the sim hangs otherwise.
 162
 163 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>
 164
 165         * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.
 166

 168
 169         * func.c (bfd_load): Add special handling of a.out executables.
 170
 171 Sat Jun 13 08:33:25 1998  Mark Alexander  <marka@cygnus.com>
 172

 174         * interf.c (run_sim): Print debugging information if verbosity level
 175         is greater than 2.
 176         (sim_open): Repeated -v options now increment verbosity level.
 177         (sim_store_register): Handle little-endian case.
 178         (flush_window): Print debugging information if verbosity level
 179         is greater then 2.
 180
 181 Tue Jun  2 15:20:35 1998  Mark Alexander  <marka@cygnus.com>
 182
 183         * interf.c (sim_open): Use revamped memory_read, which makes
 184         byte-swapping unnecessary.  Add -sparclite-board option for
 185         emulating RAM found on typical SPARClite boards.  Print
 186         error message for unrecognized option.
 187         * erc32.c: Change RAM address and size from constants to variables,
 188         to allow emulation of SPARClite board RAM.
 189         (fetch_bytes, store_bytes): New helper functions for revamped
 190         mememory_read and memory_write.
 191         (memory_read, memory_write): Rewrite to store bytes in target
 192         byte order instead of storing words in host byte order; this
 193         greatly simplifies support of little-endian programs.
 194         (get_mem_ptr): Remove unnecessary byte parameter.
 195         (sis_memory_write, sis_memory_read): Store words in target
 196         byte order instead of host byte order.
 197         (byte_swap_words): Remove, no longer needed.
 198         * sis.h ((byte_swap_words): Remove declaration, no longer needed.
 199         (memory_read): Add new sz parameter.
 200         * sis.c (run_sim): Use revamped memory_read, which makes
 201         byte-swapping unnecessary.
 202         * exec.c (dispatch_instruction): Use revamped memory_read, which
 203         makes byte-swapping and double-word fetching unnecessary.
 204         * func.c (sparclite_board): Declare new variable.
 205         (get_regi): Handle little-endian data.
 206         (bfd_load): Recognize little-endian SPARClite as having
 207         little-endian data.
 208
 209 Fri May 22 14:23:16 1998  Mark Alexander  <marka@cygnus.com>

 218         * exec.c (SDIV, SDIVCC, UDIV, UDIVCC): Define new opcodes.
 219         * (mul64): Simplify calculation of negative result.
 220         * (div64): New helper function for 64-bit division.
 221         * (dispatch_instruction): Add emulation of SDIV, SDIVCC, UDIV,
 222         and UDIVCC.
 223
 224 Wed May 13 14:59:54 1998  Mark Alexander  <marka@cygnus.com>
 225
 226         * erc32.c (close_port): Don't close stdin; it kills GDB.
 227         (byte_swap_words): New function.
 228         * sis.h: (byte_swap_words): Declare.
 229         * interf.c (run_sim): Always fetch instructions as big-endian.
 230         * sis.c (run_sim): Ditto.

 568         byte.
 569
 570 Version 2.1 26-02-96
 571 --------------------
 572
 573 * Fixed bug in "go" command.
 574
 575 version 2.0 05-02-96
 576 --------------------
 577
 578 * Fixed bug in interrupt force register (erc32.c).
 579
 580 * Change file load function to use bfd_openr.
 581
 582 * SIS should now be endian independent.
 583
 584 version 1.8 24-11-95
 585 --------------------
 586
 587 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 588   the resource dependencies right.
 589
 590 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 591   but no FPU trap is generated.
 592
 593 version 1.7.1 31-10-95
 594 --------------------
 595
 596 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 597   the FPU stays in execute mode.
 598
 599 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 600
 601
 602 version 1.7 25-10-95
 603 --------------------
 604
 605 * Interrupt during annuled instruction corrupted return address - fixed.
 606
 607
 608 version 1.6.2 25-10-95
 609 --------------------
 610
 611 * Added -DFAST_UART to Makefile
 612
 613
 614 version 1.6.1 24-10-95
 615 --------------------
 616
 617 * Fixed bug in STDFQ which caused bus error
 618
 619
 620 version 1.6 02-10-95
 621 --------------------
 622
 623 * Modified srt0.s to include code that initiates registers in IU and FPU
 624   and initializes the data segment. The simulator 'load' command does not
 625   longer initialize the data segment!
 626
 627 * Corrected MEC timer operation; scalers now divide the frequency by
 628   (scaler_value + 1).
 629
 630 * MEC breakpoints are not checked during store operation
 631
 632
 633 version 1.5 14-09-95
 634 --------------------
 635
 636 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 637
 638 * Fixed bug that allowed an annuled instruction to cause memory exception.
 639
 640 * The *ws parameter in mem.c should now contain the number of waitstates
 641   required by the memory access (was total number of cycles).
 642
 643 * The supplied srt0.s now clears the BSS (thanks Joel).
 644
 645 version 1.4 22-08-95
 646 --------------------
 647
 648 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 649 some problems on solaris 2.x machines.
 650
 651 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 652 may suffer a bit ...
 653
 654 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 655
 656 version 1.3 26-07-95
 657 --------------------
 658
 659 * Fixed bug in mulscc instruction (how could that ever have worked?)
 660
 661 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 662
 663 version 1.2 13-07-95
 664 --------------------
 665
 666 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 667 one interrupt pending)
 668
 669 * Fixed updating of condition codes during logical instructions (carry and
 670 overflow were not reset)
 671
 672 * Fixed bug in WRTBR (tt field was wrongly over-written)
 673
 674 version 1.1 07-07-95
 675 --------------------
 676
 677 * Fixed several bugs in the interrupt handler and callback routines.
 678 (reported by Paul Warren, Alsys)
