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

539 byte-swapping unnecessary. Add -sparclite-board option for
540 emulating RAM found on typical SPARClite boards. Print

922 * interf.c(sim_load): Pass the whole string, not just the first
928 * Fixed bug in "go" command.
933 * Fixed bug in interrupt force register (erc32.c).
935 * Change file load function to use bfd_openr.
937 * SIS should now be endian independent.
942 * Fixed FPU timing - some sequences of FPU instructions did not calculate
943 the resource dependencies right.
945 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
946 but no FPU trap is generated.
948 version 1.7.1 31-10-95
951 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
952 the FPU stays in execute mode.
954 * Corrected JMPL and RETT timing (these instructions takes two cycles).
960 * Interrupt during annuled instruction corrupted return address - fixed.
963 version 1.6.2 25-10-95
966 * Added -DFAST_UART to Makefile
969 version 1.6.1 24-10-95
972 * Fixed bug in STDFQ which caused bus error
978 * Modified srt0.s to include code that initiates registers in IU and FPU
979 and initializes the data segment. The simulator 'load' command does not
980 longer initialize the data segment!
982 * Corrected MEC timer operation; scalers now divide the frequency by
985 * MEC breakpoints are not checked during store operation
991 * Fixed some bugs in the cycle counting for IU & FPU instructions.
993 * Fixed bug that allowed an annuled instruction to cause memory exception.
995 * The *ws parameter in mem.c should now contain the number of waitstates
996 required by the memory access (was total number of cycles).
998 * The supplied srt0.s now clears the BSS (thanks Joel).
1000 version 1.4 22-08-95
1001 --------------------
1003 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1004 some problems on solaris 2.x machines.
1006 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1007 may suffer a bit ...
1009 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1011 version 1.3 26-07-95
1012 --------------------
1014 * Fixed bug in mulscc instruction (how could that ever have worked?)
1016 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1018 version 1.2 13-07-95
1019 --------------------
1021 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1022 one interrupt pending)
1024 * Fixed updating of condition codes during logical instructions (carry and
1025 overflow were not reset)
1027 * Fixed bug in WRTBR (tt field was wrongly over-written)
1029 version 1.1 07-07-95
1030 --------------------
1032 * Fixed several bugs in the interrupt handler and callback routines.
1033 (reported by Paul Warren, Alsys)
