 441 1999-02-11  Hugo Tyson  <hmt@cygnus.co.uk>
 442
 443         * exec.c (dispatch_instruction):
 444         Correct the sense of the
 445                   if (!sparclite) {
 446                      sregs->trap = TRAP_UNIMP;
 447                      break;
 448                   }
 449         clause that has been pasted around: it's correct in the SCAN and
 450         DIVScc (divide step) cases (where it was probably originally
 451         written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
 452         ie. instructions only in the SPARC V8 or SPARClite 86x
 453         architectures.  It was also present when not required for SMUL,
 454         SMULcc, UMUL, UMULcc instructions that are present in all
 455         architectures.
 456
 457 1999-01-25  Hugo Tyson  <hmt@cygnus.co.uk>
 458
 459         * interf.c (run_sim): Fix a bug in the main loop's handling of
 460         annulled delay slot instructions.  There is precedent for this
 461         change; the _other_ main loop in sis.c gets it right according to
 462         my reading of the code.
 463
 464         The bug is: if an interrupt happens when the next instruction
 465         (at sregs->pc) is annulled, the trap is taken (by execute_trap())
 466         with the current values of PC and NPC, so when the trap returns,
 467         the annulled instruction is indeed executed.  Another giveaway is
 468         that the annul flag is cleared in execute_trap(): the information
 469         is demonstrably discarded.
 470
 471         The solution is: perform annulling before looking for traps, in
 472         fact it's neater to do annulling, see if there's an interrupt and
 473         if not, do the instruction, then handle traps be they generated by
 474         interrupts pending or by the instruction we might just have done.
 475         That's what the sis.c one does.
 476
 477 1999-01-20  Hugo Tyson  <hmt@cygnus.co.uk>
 478
 479         * sis.h: Add asr17 register for support of SparcLITE (at least the
 480         Hitachi ones I find before me)
 481
 482         * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
 483         sparclite.  Other ASR numbers than 17 or 0 (Y) trap out.
 484         Case RDY: Allow read of asr17 if sparclite.  Other ASRs ditto.
 485         (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
 486         (init_regs): Initialize y and asr17.
 487         NB: In instruction-set space, the Y register is asr0; the
 488         instructions have different names for human reasons only.
 489
 490         * sis.c:
 491         * interf.c: Set boolean mode variable dumbio if invoked with
 492         argument "-dumbio" and mention it of verbose.
 493         * erc32.c: if "dumbio" is set, do not assume that there is a
 494         terminal type device attached to stdin/stdout.  Do not set
 495         buffering or mess with tcsetattr or do any read operations in
 496         order to make UART interrupts; not input data is supported.
 497         This is necessary to allow the sim to be used within the eCos
 498         testing infrastructure where stdin/stdout are pipes to a TCL
 499         program; the sim hangs otherwise.

 522         byte-swapping unnecessary.  Add -sparclite-board option for
 523         emulating RAM found on typical SPARClite boards.  Print
 524         error message for unrecognized option.

 904         NULL.
 905         * interf.c(sim_load): Pass the whole string, not just the first
 906         byte.
 907
 908 Version 2.1 26-02-96
 909 --------------------
 910
 911 * Fixed bug in "go" command.
 912
 913 version 2.0 05-02-96
 914 --------------------
 915
 916 * Fixed bug in interrupt force register (erc32.c).
 917
 918 * Change file load function to use bfd_openr.
 919
 920 * SIS should now be endian independent.
 921
 922 version 1.8 24-11-95
 923 --------------------
 924
 925 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 926   the resource dependencies right.
 927
 928 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 929   but no FPU trap is generated.
 930
 931 version 1.7.1 31-10-95
 932 --------------------
 933
 934 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 935   the FPU stays in execute mode.
 936
 937 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 938
 939
 940 version 1.7 25-10-95
 941 --------------------
 942
 943 * Interrupt during annuled instruction corrupted return address - fixed.
 944
 945
 946 version 1.6.2 25-10-95
 947 --------------------
 948
 949 * Added -DFAST_UART to Makefile
 950
 951
 952 version 1.6.1 24-10-95
 953 --------------------
 954
 955 * Fixed bug in STDFQ which caused bus error
 956
 957
 958 version 1.6 02-10-95
 959 --------------------
 960
 961 * Modified srt0.s to include code that initiates registers in IU and FPU
 962   and initializes the data segment. The simulator 'load' command does not
 963   longer initialize the data segment!
 964
 965 * Corrected MEC timer operation; scalers now divide the frequency by
 966   (scaler_value + 1).
 967
 968 * MEC breakpoints are not checked during store operation
 969
 970
 971 version 1.5 14-09-95
 972 --------------------
 973
 974 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 975
 976 * Fixed bug that allowed an annuled instruction to cause memory exception.
 977
 978 * The *ws parameter in mem.c should now contain the number of waitstates
 979   required by the memory access (was total number of cycles).
 980
 981 * The supplied srt0.s now clears the BSS (thanks Joel).
 982
 983 version 1.4 22-08-95
 984 --------------------
 985
 986 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 987 some problems on solaris 2.x machines.
 988
 989 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 990 may suffer a bit ...
 991
 992 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 993
 994 version 1.3 26-07-95
 995 --------------------
 996
 997 * Fixed bug in mulscc instruction (how could that ever have worked?)
 998
 999 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1000
1001 version 1.2 13-07-95
1002 --------------------
1003
1004 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1005 one interrupt pending)
1006
1007 * Fixed updating of condition codes during logical instructions (carry and
1008 overflow were not reset)
1009
1010 * Fixed bug in WRTBR (tt field was wrongly over-written)
1011
1012 version 1.1 07-07-95
1013 --------------------
1014
1015 * Fixed several bugs in the interrupt handler and callback routines.
1016 (reported by Paul Warren, Alsys)
