 462 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 463
 464         * exec.c (dispatch_instruction):
 465         Correct the sense of the
 466                   if (!sparclite) {
 467                      sregs->trap = TRAP_UNIMP;
 468                      break;
 469                   }
 470         clause that has been pasted around: it's correct in the SCAN and
 471         DIVScc (divide step) cases (where it was probably originally
 472         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 473         ie. instructions only in the SPARC V8 or SPARClite 86x
 474         architectures.  It was also present when not required for SMUL,
 475         SMULcc, UMUL, UMULcc instructions that are present in all
 476         architectures.
 477
 478 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 479
 480         * interf.c (run_sim): Fix a bug in the main loop's handling of
 481         annulled delay slot instructions.  There is precedent for this
 482         change; the _other_ main loop in sis.c gets it right according to
 483         my reading of the code.
 484
 485         The bug is: if an interrupt happens when the next instruction
 486         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 487         with the current values of PC and NPC, so when the trap returns,
 488         the annulled instruction is indeed executed.  Another giveaway is
 489         that the annul flag is cleared in execute_trap(): the information
 490         is demonstrably discarded.
 491
 492         The solution is: perform annulling before looking for traps, in
 493         fact it's neater to do annulling, see if there's an interrupt and
 494         if not, do the instruction, then handle traps be they generated by
 495         interrupts pending or by the instruction we might just have done.
 496         That's what the sis.c one does.
 497
 498 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 499
 500         * sis.h: Add asr17 register for support of SparcLITE (at least the
 501         Hitachi ones I find before me)
 502
 503         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 504         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 505         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 506         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 507         (init_regs): Initialize y and asr17.
 508         NB: In instruction-set space, the Y register is asr0; the
 509         instructions have different names for human reasons only.
 510
 511         * sis.c:
 512         * interf.c: Set boolean mode variable dumbio if invoked with
 513         argument "-dumbio" and mention it of verbose.
 514         * erc32.c: if "dumbio" is set, do not assume that there is a
 515         terminal type device attached to stdin/stdout.  Do not set
 516         buffering or mess with tcsetattr or do any read operations in
 517         order to make UART interrupts; not input data is supported.
 518         This is necessary to allow the sim to be used within the eCos
 519         testing infrastructure where stdin/stdout are pipes to a TCL
 520         program; the sim hangs otherwise.

 542         * interf.c (sim_open): Use revamped memory_read, which makes
 543         byte-swapping unnecessary.  Add -sparclite-board option for
 544         emulating RAM found on typical SPARClite boards.  Print
 545         error message for unrecognized option.
 546         * erc32.c: Change RAM address and size from constants to variables,
 547         to allow emulation of SPARClite board RAM.

 553         (get_mem_ptr): Remove unnecessary byte parameter.
 554         (sis_memory_write, sis_memory_read): Store words in target

 559         * sis.c (run_sim): Use revamped memory_read, which makes
 560         byte-swapping unnecessary.
 561         * exec.c (dispatch_instruction): Use revamped memory_read, which

 564         (get_regi): Handle little-endian data.
 565         (bfd_load): Recognize little-endian SPARClite as having

 926         * interf.c(sim_load): Pass the whole string, not just the first
 927         byte.
 928
 929 Version 2.1 26-02-96
 930 --------------------
 931
 932 * Fixed bug in "go" command.
 933
 934 version 2.0 05-02-96
 935 --------------------
 936
 937 * Fixed bug in interrupt force register (erc32.c).
 938
 939 * Change file load function to use bfd_openr.
 940
 941 * SIS should now be endian independent.
 942
 943 version 1.8 24-11-95
 944 --------------------
 945
 946 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 947   the resource dependencies right.
 948
 949 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 950   but no FPU trap is generated.
 951
 952 version 1.7.1 31-10-95
 953 --------------------
 954
 955 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 956   the FPU stays in execute mode.
 957
 958 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 959
 960
 961 version 1.7 25-10-95
 962 --------------------
 963
 964 * Interrupt during annuled instruction corrupted return address - fixed.
 965
 966
 967 version 1.6.2 25-10-95
 968 --------------------
 969
 970 * Added -DFAST_UART to Makefile
 971
 972
 973 version 1.6.1 24-10-95
 974 --------------------
 975
 976 * Fixed bug in STDFQ which caused bus error
 977
 978
 979 version 1.6 02-10-95
 980 --------------------
 981
 982 * Modified srt0.s to include code that initiates registers in IU and FPU
 983   and initializes the data segment. The simulator 'load' command does not
 984   longer initialize the data segment!
 985
 986 * Corrected MEC timer operation; scalers now divide the frequency by
 987   (scaler_value + 1).
 988
 989 * MEC breakpoints are not checked during store operation
 990
 991
 992 version 1.5 14-09-95
 993 --------------------
 994
 995 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 996
 997 * Fixed bug that allowed an annuled instruction to cause memory exception.
 998
 999 * The *ws parameter in mem.c should now contain the number of waitstates
1000   required by the memory access (was total number of cycles).
1001
1002 * The supplied srt0.s now clears the BSS (thanks Joel).
1003
1004 version 1.4 22-08-95
1005 --------------------
1006
1007 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1008 some problems on solaris 2.x machines.
1009
1010 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1011 may suffer a bit ...
1012
1013 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1014
1015 version 1.3 26-07-95
1016 --------------------
1017
1018 * Fixed bug in mulscc instruction (how could that ever have worked?)
1019
1020 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1021
1022 version 1.2 13-07-95
1023 --------------------
1024
1025 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1026 one interrupt pending)
1027
1028 * Fixed updating of condition codes during logical instructions (carry and
1029 overflow were not reset)
1030
1031 * Fixed bug in WRTBR (tt field was wrongly over-written)
1032
1033 version 1.1 07-07-95
1034 --------------------
1035
1036 * Fixed several bugs in the interrupt handler and callback routines.
1037 (reported by Paul Warren, Alsys)
