 450 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 451
 452         * exec.c (dispatch_instruction):
 453         Correct the sense of the
 454                   if (!sparclite) {
 455                      sregs->trap = TRAP_UNIMP;
 456                      break;
 457                   }
 458         clause that has been pasted around: it's correct in the SCAN and
 459         DIVScc (divide step) cases (where it was probably originally
 460         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 461         ie. instructions only in the SPARC V8 or SPARClite 86x
 462         architectures.  It was also present when not required for SMUL,
 463         SMULcc, UMUL, UMULcc instructions that are present in all
 464         architectures.
 465
 466 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 467
 468         * interf.c (run_sim): Fix a bug in the main loop's handling of
 469         annulled delay slot instructions.  There is precedent for this
 470         change; the _other_ main loop in sis.c gets it right according to
 471         my reading of the code.
 472
 473         The bug is: if an interrupt happens when the next instruction
 474         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 475         with the current values of PC and NPC, so when the trap returns,
 476         the annulled instruction is indeed executed.  Another giveaway is
 477         that the annul flag is cleared in execute_trap(): the information
 478         is demonstrably discarded.
 479
 480         The solution is: perform annulling before looking for traps, in
 481         fact it's neater to do annulling, see if there's an interrupt and
 482         if not, do the instruction, then handle traps be they generated by
 483         interrupts pending or by the instruction we might just have done.
 484         That's what the sis.c one does.
 485
 486 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 487
 488         * sis.h: Add asr17 register for support of SparcLITE (at least the
 489         Hitachi ones I find before me)
 490
 491         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 492         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 493         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 494         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 495         (init_regs): Initialize y and asr17.
 496         NB: In instruction-set space, the Y register is asr0; the
 497         instructions have different names for human reasons only.
 498
 499         * sis.c:
 500         * interf.c: Set boolean mode variable dumbio if invoked with
 501         argument "-dumbio" and mention it of verbose.
 502         * erc32.c: if "dumbio" is set, do not assume that there is a
 503         terminal type device attached to stdin/stdout.  Do not set
 504         buffering or mess with tcsetattr or do any read operations in
 505         order to make UART interrupts; not input data is supported.
 506         This is necessary to allow the sim to be used within the eCos
 507         testing infrastructure where stdin/stdout are pipes to a TCL
 508         program; the sim hangs otherwise.

 531         byte-swapping unnecessary.  Add -sparclite-board option for
 532         emulating RAM found on typical SPARClite boards.  Print
 533         error message for unrecognized option.
 534         * erc32.c: Change RAM address and size from constants to variables,
 535         to allow emulation of SPARClite board RAM.

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

 913         NULL.
 914         * interf.c(sim_load): Pass the whole string, not just the first
 915         byte.
 916
 917 Version 2.1 26-02-96
 918 --------------------
 919
 920 * Fixed bug in "go" command.
 921
 922 version 2.0 05-02-96
 923 --------------------
 924
 925 * Fixed bug in interrupt force register (erc32.c).
 926
 927 * Change file load function to use bfd_openr.
 928
 929 * SIS should now be endian independent.
 930
 931 version 1.8 24-11-95
 932 --------------------
 933
 934 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 935   the resource dependencies right.
 936
 937 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 938   but no FPU trap is generated.
 939
 940 version 1.7.1 31-10-95
 941 --------------------
 942
 943 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 944   the FPU stays in execute mode.
 945
 946 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 947
 948
 949 version 1.7 25-10-95
 950 --------------------
 951
 952 * Interrupt during annuled instruction corrupted return address - fixed.
 953
 954
 955 version 1.6.2 25-10-95
 956 --------------------
 957
 958 * Added -DFAST_UART to Makefile
 959
 960
 961 version 1.6.1 24-10-95
 962 --------------------
 963
 964 * Fixed bug in STDFQ which caused bus error
 965
 966
 967 version 1.6 02-10-95
 968 --------------------
 969
 970 * Modified srt0.s to include code that initiates registers in IU and FPU
 971   and initializes the data segment. The simulator 'load' command does not
 972   longer initialize the data segment!
 973
 974 * Corrected MEC timer operation; scalers now divide the frequency by
 975   (scaler_value + 1).
 976
 977 * MEC breakpoints are not checked during store operation
 978
 979
 980 version 1.5 14-09-95
 981 --------------------
 982
 983 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 984
 985 * Fixed bug that allowed an annuled instruction to cause memory exception.
 986
 987 * The *ws parameter in mem.c should now contain the number of waitstates
 988   required by the memory access (was total number of cycles).
 989
 990 * The supplied srt0.s now clears the BSS (thanks Joel).
 991
 992 version 1.4 22-08-95
 993 --------------------
 994
 995 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 996 some problems on solaris 2.x machines.
 997
 998 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 999 may suffer a bit ...
1000
1001 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1002
1003 version 1.3 26-07-95
1004 --------------------
1005
1006 * Fixed bug in mulscc instruction (how could that ever have worked?)
1007
1008 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1009
1010 version 1.2 13-07-95
1011 --------------------
1012
1013 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1014 one interrupt pending)
1015
1016 * Fixed updating of condition codes during logical instructions (carry and
1017 overflow were not reset)
1018
1019 * Fixed bug in WRTBR (tt field was wrongly over-written)
1020
1021 version 1.1 07-07-95
1022 --------------------
1023
1024 * Fixed several bugs in the interrupt handler and callback routines.
1025 (reported by Paul Warren, Alsys)
