 422
 423 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 424
 425         * exec.c (dispatch_instruction):
 426         Correct the sense of the
 427                   if (!sparclite) {
 428                      sregs->trap = TRAP_UNIMP;
 429                      break;
 430                   }
 431         clause that has been pasted around: it's correct in the SCAN and
 432         DIVScc (divide step) cases (where it was probably originally
 433         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 434         ie. instructions only in the SPARC V8 or SPARClite 86x
 435         architectures.  It was also present when not required for SMUL,
 436         SMULcc, UMUL, UMULcc instructions that are present in all
 437         architectures.
 438
 439 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 440
 441         * interf.c (run_sim): Fix a bug in the main loop's handling of
 442         annulled delay slot instructions.  There is precedent for this
 443         change; the _other_ main loop in sis.c gets it right according to
 444         my reading of the code.
 445
 446         The bug is: if an interrupt happens when the next instruction
 447         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 448         with the current values of PC and NPC, so when the trap returns,
 449         the annulled instruction is indeed executed.  Another giveaway is
 450         that the annul flag is cleared in execute_trap(): the information
 451         is demonstrably discarded.
 452
 453         The solution is: perform annulling before looking for traps, in
 454         fact it's neater to do annulling, see if there's an interrupt and
 455         if not, do the instruction, then handle traps be they generated by
 456         interrupts pending or by the instruction we might just have done.
 457         That's what the sis.c one does.
 458
 459 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 460
 461         * sis.h: Add asr17 register for support of SparcLITE (at least the
 462         Hitachi ones I find before me)
 463
 464         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 465         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 466         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 467         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 468         (init_regs): Initialize y and asr17.
 469         NB: In instruction-set space, the Y register is asr0; the
 470         instructions have different names for human reasons only.
 471
 472         * sis.c:
 473         * interf.c: Set boolean mode variable dumbio if invoked with
 474         argument "-dumbio" and mention it of verbose.
 475         * erc32.c: if "dumbio" is set, do not assume that there is a
 476         terminal type device attached to stdin/stdout.  Do not set
 477         buffering or mess with tcsetattr or do any read operations in
 478         order to make UART interrupts; not input data is supported.
 479         This is necessary to allow the sim to be used within the eCos
 480         testing infrastructure where stdin/stdout are pipes to a TCL
 481         program; the sim hangs otherwise.
 482
 483 Thu Jul 23 07:17:03 1998  Mark Alexander  <marka@cygnus.com>
 484

 502
 503         * interf.c (sim_open): Use revamped memory_read, which makes
 504         byte-swapping unnecessary.  Add -sparclite-board option for
 505         emulating RAM found on typical SPARClite boards.  Print
 506         error message for unrecognized option.
 507         * erc32.c: Change RAM address and size from constants to variables,
 508         to allow emulation of SPARClite board RAM.
 509         (fetch_bytes, store_bytes): New helper functions for revamped

 511         (memory_read, memory_write): Rewrite to store bytes in target

 513         greatly simplifies support of little-endian programs.
 514         (get_mem_ptr): Remove unnecessary byte parameter.
 515         (sis_memory_write, sis_memory_read): Store words in target
 516         byte order instead of host byte order.

 520         * sis.c (run_sim): Use revamped memory_read, which makes
 521         byte-swapping unnecessary.
 522         * exec.c (dispatch_instruction): Use revamped memory_read, which
 523         makes byte-swapping and double-word fetching unnecessary.

 525         (get_regi): Handle little-endian data.
 526         (bfd_load): Recognize little-endian SPARClite as having

 787
 788         * Makefile.in (run.o): Remove this rule, it hides the one in

 835
 836         * erc32.c:  Don't include sys/ioctl.h or sys/file.h.  They aren't
 837         necessary.
 838         * (port_init):  Don't even *try* to open pty's under _WIN32.
 839         * Use SIM_ADDR, not caddr_t for declaring vars that hold addresses.

 886         NULL.
 887         * interf.c(sim_load): Pass the whole string, not just the first
 888         byte.
 889
 890 Version 2.1 26-02-96
 891 --------------------
 892
 893 * Fixed bug in "go" command.
 894
 895 version 2.0 05-02-96
 896 --------------------
 897
 898 * Fixed bug in interrupt force register (erc32.c).
 899
 900 * Change file load function to use bfd_openr.
 901
 902 * SIS should now be endian independent.
 903
 904 version 1.8 24-11-95
 905 --------------------
 906
 907 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 908   the resource dependencies right.
 909
 910 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 911   but no FPU trap is generated.
 912
 913 version 1.7.1 31-10-95
 914 --------------------
 915
 916 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 917   the FPU stays in execute mode.
 918
 919 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 920
 921
 922 version 1.7 25-10-95
 923 --------------------
 924
 925 * Interrupt during annuled instruction corrupted return address - fixed.
 926
 927
 928 version 1.6.2 25-10-95
 929 --------------------
 930
 931 * Added -DFAST_UART to Makefile
 932
 933
 934 version 1.6.1 24-10-95
 935 --------------------
 936
 937 * Fixed bug in STDFQ which caused bus error
 938
 939
 940 version 1.6 02-10-95
 941 --------------------
 942
 943 * Modified srt0.s to include code that initiates registers in IU and FPU
 944   and initializes the data segment. The simulator 'load' command does not
 945   longer initialize the data segment!
 946
 947 * Corrected MEC timer operation; scalers now divide the frequency by
 948   (scaler_value + 1).
 949
 950 * MEC breakpoints are not checked during store operation
 951
 952
 953 version 1.5 14-09-95
 954 --------------------
 955
 956 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 957
 958 * Fixed bug that allowed an annuled instruction to cause memory exception.
 959
 960 * The *ws parameter in mem.c should now contain the number of waitstates
 961   required by the memory access (was total number of cycles).
 962
 963 * The supplied srt0.s now clears the BSS (thanks Joel).
 964
 965 version 1.4 22-08-95
 966 --------------------
 967
 968 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 969 some problems on solaris 2.x machines.
 970
 971 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 972 may suffer a bit ...
 973
 974 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 975
 976 version 1.3 26-07-95
 977 --------------------
 978
 979 * Fixed bug in mulscc instruction (how could that ever have worked?)
 980
 981 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
 982
 983 version 1.2 13-07-95
 984 --------------------
 985
 986 * Fixed bug in interrupt handling (wrong interrupt selected when more that
 987 one interrupt pending)
 988
 989 * Fixed updating of condition codes during logical instructions (carry and
 990 overflow were not reset)
 991
 992 * Fixed bug in WRTBR (tt field was wrongly over-written)
 993
 994 version 1.1 07-07-95
 995 --------------------
 996
 997 * Fixed several bugs in the interrupt handler and callback routines.
 998 (reported by Paul Warren, Alsys)
