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

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

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

 909         NULL.
 910         * interf.c(sim_load): Pass the whole string, not just the first
 911         byte.
 912
 913 Version 2.1 26-02-96
 914 --------------------
 915
 916 * Fixed bug in "go" command.
 917
 918 version 2.0 05-02-96
 919 --------------------
 920
 921 * Fixed bug in interrupt force register (erc32.c).
 922
 923 * Change file load function to use bfd_openr.
 924
 925 * SIS should now be endian independent.
 926
 927 version 1.8 24-11-95
 928 --------------------
 929
 930 * Fixed FPU timing - some sequences of FPU instructions did not calculate
 931   the resource dependencies right.
 932
 933 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
 934   but no FPU trap is generated.
 935
 936 version 1.7.1 31-10-95
 937 --------------------
 938
 939 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
 940   the FPU stays in execute mode.
 941
 942 * Corrected JMPL and RETT timing (these instructions takes two cycles).
 943
 944
 945 version 1.7 25-10-95
 946 --------------------
 947
 948 * Interrupt during annuled instruction corrupted return address - fixed.
 949
 950
 951 version 1.6.2 25-10-95
 952 --------------------
 953
 954 * Added -DFAST_UART to Makefile
 955
 956
 957 version 1.6.1 24-10-95
 958 --------------------
 959
 960 * Fixed bug in STDFQ which caused bus error
 961
 962
 963 version 1.6 02-10-95
 964 --------------------
 965
 966 * Modified srt0.s to include code that initiates registers in IU and FPU
 967   and initializes the data segment. The simulator 'load' command does not
 968   longer initialize the data segment!
 969
 970 * Corrected MEC timer operation; scalers now divide the frequency by
 971   (scaler_value + 1).
 972
 973 * MEC breakpoints are not checked during store operation
 974
 975
 976 version 1.5 14-09-95
 977 --------------------
 978
 979 * Fixed some bugs in the cycle counting for IU & FPU instructions.
 980
 981 * Fixed bug that allowed an annuled instruction to cause memory exception.
 982
 983 * The *ws parameter in mem.c should now contain the number of waitstates
 984   required by the memory access (was total number of cycles).
 985
 986 * The supplied srt0.s now clears the BSS (thanks Joel).
 987
 988 version 1.4 22-08-95
 989 --------------------
 990
 991 * Added a '-g' switch to enable/disable the GNU readline(), which cause
 992 some problems on solaris 2.x machines.
 993
 994 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
 995 may suffer a bit ...
 996
 997 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
 998
 999 version 1.3 26-07-95
1000 --------------------
1001
1002 * Fixed bug in mulscc instruction (how could that ever have worked?)
1003
1004 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1005
1006 version 1.2 13-07-95
1007 --------------------
1008
1009 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1010 one interrupt pending)
1011
1012 * Fixed updating of condition codes during logical instructions (carry and
1013 overflow were not reset)
1014
1015 * Fixed bug in WRTBR (tt field was wrongly over-written)
1016
1017 version 1.1 07-07-95
1018 --------------------
1019
1020 * Fixed several bugs in the interrupt handler and callback routines.
1021 (reported by Paul Warren, Alsys)
