 226
 227         * exec.c (dispatch_instruction):
 228         Correct the sense of the
 229                   if (!sparclite) {
 230                      sregs->trap = TRAP_UNIMP;
 231                      break;
 232                   }
 233         clause that has been pasted around: it's correct in the SCAN and
 234         DIVScc (divide step) cases (where it was probably originally
 235         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 236         ie. instructions only in the SPARC V8 or SPARClite 86x
 237         architectures.  It was also present when not required for SMUL,
 238         SMULcc, UMUL, UMULcc instructions that are present in all
 239         architectures.
 240
 241 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 242
 243         * interf.c (run_sim): Fix a bug in the main loop's handling of
 244         annulled delay slot instructions.  There is precedent for this
 245         change; the _other_ main loop in sis.c gets it right according to
 246         my reading of the code.
 247
 248         The bug is: if an interrupt happens when the next instruction
 249         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 250         with the current values of PC and NPC, so when the trap returns,
 251         the annulled instruction is indeed executed.  Another giveaway is
 252         that the annul flag is cleared in execute_trap(): the information
 253         is demonstrably discarded.
 254
 255         The solution is: perform annulling before looking for traps, in
 256         fact it's neater to do annulling, see if there's an interrupt and
 257         if not, do the instruction, then handle traps be they generated by
 258         interrupts pending or by the instruction we might just have done.
 259         That's what the sis.c one does.
 260
 261 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 262
 263         * sis.h: Add asr17 register for support of SparcLITE (at least the
 264         Hitachi ones I find before me)
 265
 266         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 267         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 268         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 269         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 270         (init_regs): Initialize y and asr17.
 271         NB: In instruction-set space, the Y register is asr0; the
 272         instructions have different names for human reasons only.
 273
 274         * sis.c:
 275         * interf.c: Set boolean mode variable dumbio if invoked with
 276         argument "-dumbio" and mention it of verbose.
 277         * erc32.c: if "dumbio" is set, do not assume that there is a
 278         terminal type device attached to stdin/stdout.  Do not set
 279         buffering or mess with tcsetattr or do any read operations in
 280         order to make UART interrupts; not input data is supported.
 281         This is necessary to allow the sim to be used within the eCos
 282         testing infrastructure where stdin/stdout are pipes to a TCL
 283         program; the sim hangs otherwise.

 298         (sim_open): Repeated -v options now increment verbosity level.
 299         (sim_store_register): Handle little-endian case.

 304
 305         * interf.c (sim_open): Use revamped memory_read, which makes
 306         byte-swapping unnecessary.  Add -sparclite-board option for
 307         emulating RAM found on typical SPARClite boards.  Print
 308         error message for unrecognized option.
 309         * erc32.c: Change RAM address and size from constants to variables,
 310         to allow emulation of SPARClite board RAM.
 311         (fetch_bytes, store_bytes): New helper functions for revamped
 312         mememory_read and memory_write.
 313         (memory_read, memory_write): Rewrite to store bytes in target
 314         byte order instead of storing words in host byte order; this
 315         greatly simplifies support of little-endian programs.
 316         (get_mem_ptr): Remove unnecessary byte parameter.
 317         (sis_memory_write, sis_memory_read): Store words in target
 318         byte order instead of host byte order.
 319         (byte_swap_words): Remove, no longer needed.
 320         * sis.h ((byte_swap_words): Remove declaration, no longer needed.
 321         (memory_read): Add new sz parameter.
 322         * sis.c (run_sim): Use revamped memory_read, which makes
 323         byte-swapping unnecessary.
 324         * exec.c (dispatch_instruction): Use revamped memory_read, which
 325         makes byte-swapping and double-word fetching unnecessary.
 326         * func.c (sparclite_board): Declare new variable.
 327         (get_regi): Handle little-endian data.
 328         (bfd_load): Recognize little-endian SPARClite as having
 329         little-endian data.

 689         * interf.c(sim_load): Pass the whole string, not just the first
 690         byte.
 691
 692 Version 2.1 26-02-96
 693 --------------------
 694
 695 * Fixed bug in "go" command.
 696
 697 version 2.0 05-02-96
 698 --------------------
 699
 700 * Fixed bug in interrupt force register (erc32.c).
 701
 702 * Change file load function to use bfd_openr.
 703
 704 * SIS should now be endian independent.
 705
 706 version 1.8 24-11-95
 707 --------------------
 708
 709 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 710   the resource dependencies right.
 711
 712 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 713   but no FPU trap is generated.
 714
 715 version 1.7.1 31-10-95
 716 --------------------
 717
 718 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 719   the FPU stays in execute mode.
 720
 721 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 722
 723
 724 version 1.7 25-10-95
 725 --------------------
 726
 727 * Interrupt during annuled instruction corrupted return address - fixed.
 728
 729
 730 version 1.6.2 25-10-95
 731 --------------------
 732
 733 * Added -DFAST_UART to Makefile
 734
 735
 736 version 1.6.1 24-10-95
 737 --------------------
 738
 739 * Fixed bug in STDFQ which caused bus error
 740
 741
 742 version 1.6 02-10-95
 743 --------------------
 744
 745 * Modified srt0.s to include code that initiates registers in IU and FPU
 746   and initializes the data segment. The simulator 'load' command does not
 747   longer initialize the data segment!
 748
 749 * Corrected MEC timer operation; scalers now divide the frequency by
 750   (scaler_value + 1).
 751
 752 * MEC breakpoints are not checked during store operation
 753
 754
 755 version 1.5 14-09-95
 756 --------------------
 757
 758 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 759
 760 * Fixed bug that allowed an annuled instruction to cause memory exception.
 761
 762 * The *ws parameter in mem.c should now contain the number of waitstates
 763   required by the memory access (was total number of cycles).
 764
 765 * The supplied srt0.s now clears the BSS (thanks Joel).
 766
 767 version 1.4 22-08-95
 768 --------------------
 769
 770 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 771 some problems on solaris 2.x machines.
 772
 773 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 774 may suffer a bit ...
 775
 776 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 777
 778 version 1.3 26-07-95
