555 1999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
557 * exec.c (dispatch_instruction):
558 Correct the sense of the
560 sregs->trap = TRAP_UNIMP;
563 clause that has been pasted around: it's correct in the SCAN and
564 DIVScc (divide step) cases (where it was probably originally
565 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
566 ie. instructions only in the SPARC V8 or SPARClite 86x
567 architectures. It was also present when not required for SMUL,
568 SMULcc, UMUL, UMULcc instructions that are present in all
571 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
573 * interf.c (run_sim): Fix a bug in the main loop's handling of
574 annulled delay slot instructions. There is precedent for this
575 change; the _other_ main loop in sis.c gets it right according to
576 my reading of the code.
578 The bug is: if an interrupt happens when the next instruction
579 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
580 with the current values of PC and NPC, so when the trap returns,
581 the annulled instruction is indeed executed. Another giveaway is
582 that the annul flag is cleared in execute_trap(): the information
583 is demonstrably discarded.
585 The solution is: perform annulling before looking for traps, in
586 fact it's neater to do annulling, see if there's an interrupt and
587 if not, do the instruction, then handle traps be they generated by
588 interrupts pending or by the instruction we might just have done.
589 That's what the sis.c one does.
591 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
593 * sis.h: Add asr17 register for support of SparcLITE (at least the
594 Hitachi ones I find before me)
596 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
597 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
598 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
599 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
600 (init_regs): Initialize y and asr17.
601 NB: In instruction-set space, the Y register is asr0; the
602 instructions have different names for human reasons only.
605 * interf.c: Set boolean mode variable dumbio if invoked with
606 argument "-dumbio" and mention it of verbose.
607 * erc32.c: if "dumbio" is set, do not assume that there is a
608 terminal type device attached to stdin/stdout. Do not set
609 buffering or mess with tcsetattr or do any read operations in
610 order to make UART interrupts; not input data is supported.
611 This is necessary to allow the sim to be used within the eCos
612 testing infrastructure where stdin/stdout are pipes to a TCL
613 program; the sim hangs otherwise.

1023 --------------------
1025 * Fixed bug in "go" command.
1027 version 2.0 05-02-96
1028 --------------------
1030 * Fixed bug in interrupt force register (erc32.c).
1032 * Change file load function to use bfd_openr.
1034 * SIS should now be endian independent.
1036 version 1.8 24-11-95
1037 --------------------
1039 * Fixed FPU timing - some sequences of FPU instructions did not calculate
1040 the resource dependencies right.
1042 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
1043 but no FPU trap is generated.
1045 version 1.7.1 31-10-95
1046 --------------------
1048 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
1049 the FPU stays in execute mode.
1051 * Corrected JMPL and RETT timing (these instructions takes two cycles).
1054 version 1.7 25-10-95
1055 --------------------
1057 * Interrupt during annuled instruction corrupted return address - fixed.
1060 version 1.6.2 25-10-95
1061 --------------------
1063 * Added -DFAST_UART to Makefile
1066 version 1.6.1 24-10-95
1067 --------------------
1069 * Fixed bug in STDFQ which caused bus error
1072 version 1.6 02-10-95
1073 --------------------
1075 * Modified srt0.s to include code that initiates registers in IU and FPU
1076 and initializes the data segment. The simulator 'load' command does not
1077 longer initialize the data segment!
1079 * Corrected MEC timer operation; scalers now divide the frequency by
1082 * MEC breakpoints are not checked during store operation
1085 version 1.5 14-09-95
1086 --------------------
1088 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1090 * Fixed bug that allowed an annuled instruction to cause memory exception.
1092 * The *ws parameter in mem.c should now contain the number of waitstates
1093 required by the memory access (was total number of cycles).
1095 * The supplied srt0.s now clears the BSS (thanks Joel).
1097 version 1.4 22-08-95
1098 --------------------
1100 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1101 some problems on solaris 2.x machines.
1103 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1104 may suffer a bit ...
1106 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1108 version 1.3 26-07-95
1109 --------------------
1111 * Fixed bug in mulscc instruction (how could that ever have worked?)
1113 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1115 version 1.2 13-07-95
1116 --------------------
1118 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1119 one interrupt pending)
1121 * Fixed updating of condition codes during logical instructions (carry and
1122 overflow were not reset)
1124 * Fixed bug in WRTBR (tt field was wrongly over-written)
1126 version 1.1 07-07-95
1127 --------------------
1129 * Fixed several bugs in the interrupt handler and callback routines.
1130 (reported by Paul Warren, Alsys)
