532 * configure: regenerate
534 1999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
536 * exec.c (dispatch_instruction):
537 Correct the sense of the
539 sregs->trap = TRAP_UNIMP;
542 clause that has been pasted around: it's correct in the SCAN and
543 DIVScc (divide step) cases (where it was probably originally
544 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
545 ie. instructions only in the SPARC V8 or SPARClite 86x
546 architectures. It was also present when not required for SMUL,
547 SMULcc, UMUL, UMULcc instructions that are present in all
550 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
552 * interf.c (run_sim): Fix a bug in the main loop's handling of
553 annulled delay slot instructions. There is precedent for this
554 change; the _other_ main loop in sis.c gets it right according to
555 my reading of the code.
557 The bug is: if an interrupt happens when the next instruction
558 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
559 with the current values of PC and NPC, so when the trap returns,
560 the annulled instruction is indeed executed. Another giveaway is
561 that the annul flag is cleared in execute_trap(): the information
562 is demonstrably discarded.
564 The solution is: perform annulling before looking for traps, in
565 fact it's neater to do annulling, see if there's an interrupt and
566 if not, do the instruction, then handle traps be they generated by
567 interrupts pending or by the instruction we might just have done.
568 That's what the sis.c one does.
570 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
572 * sis.h: Add asr17 register for support of SparcLITE (at least the
573 Hitachi ones I find before me)
575 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
576 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
577 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
578 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
579 (init_regs): Initialize y and asr17.
580 NB: In instruction-set space, the Y register is asr0; the
581 instructions have different names for human reasons only.
584 * interf.c: Set boolean mode variable dumbio if invoked with
585 argument "-dumbio" and mention it of verbose.
586 * erc32.c: if "dumbio" is set, do not assume that there is a
587 terminal type device attached to stdin/stdout. Do not set
588 buffering or mess with tcsetattr or do any read operations in
589 order to make UART interrupts; not input data is supported.
590 This is necessary to allow the sim to be used within the eCos
591 testing infrastructure where stdin/stdout are pipes to a TCL
592 program; the sim hangs otherwise.

1001 Version 2.1 26-02-96
1002 --------------------
1004 * Fixed bug in "go" command.
1006 version 2.0 05-02-96
1007 --------------------
1009 * Fixed bug in interrupt force register (erc32.c).
1011 * Change file load function to use bfd_openr.
1013 * SIS should now be endian independent.
1015 version 1.8 24-11-95
1016 --------------------
1018 * Fixed FPU timing - some sequences of FPU instructions did not calculate
1019 the resource dependencies right.
1021 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
1022 but no FPU trap is generated.
1024 version 1.7.1 31-10-95
1025 --------------------
1027 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1028 the FPU stays in execute mode.
1030 * Corrected JMPL and RETT timing (these instructions takes two cycles).
1033 version 1.7 25-10-95
1034 --------------------
1036 * Interrupt during annuled instruction corrupted return address - fixed.
1039 version 1.6.2 25-10-95
1040 --------------------
1042 * Added -DFAST_UART to Makefile
1045 version 1.6.1 24-10-95
1046 --------------------
1048 * Fixed bug in STDFQ which caused bus error
1051 version 1.6 02-10-95
1052 --------------------
1054 * Modified srt0.s to include code that initiates registers in IU and FPU
1055 and initializes the data segment. The simulator 'load' command does not
1056 longer initialize the data segment!
1058 * Corrected MEC timer operation; scalers now divide the frequency by
1061 * MEC breakpoints are not checked during store operation
1064 version 1.5 14-09-95
1065 --------------------
1067 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1069 * Fixed bug that allowed an annuled instruction to cause memory exception.
1071 * The *ws parameter in mem.c should now contain the number of waitstates
1072 required by the memory access (was total number of cycles).
1074 * The supplied srt0.s now clears the BSS (thanks Joel).
1076 version 1.4 22-08-95
1077 --------------------
1079 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1080 some problems on solaris 2.x machines.
1082 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1083 may suffer a bit ...
1085 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1087 version 1.3 26-07-95
1088 --------------------
1090 * Fixed bug in mulscc instruction (how could that ever have worked?)
1092 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1094 version 1.2 13-07-95
1095 --------------------
1097 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1098 one interrupt pending)
1100 * Fixed updating of condition codes during logical instructions (carry and
1101 overflow were not reset)
1103 * Fixed bug in WRTBR (tt field was wrongly over-written)
1105 version 1.1 07-07-95
1106 --------------------
1108 * Fixed several bugs in the interrupt handler and callback routines.
1109 (reported by Paul Warren, Alsys)
