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

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

916 * func.c(bfd_load): Don't try to print the filename if the pfbd is
918 * interf.c(sim_load): Pass the whole string, not just the first
924 * Fixed bug in "go" command.
929 * Fixed bug in interrupt force register (erc32.c).
931 * Change file load function to use bfd_openr.
933 * SIS should now be endian independent.
938 * Fixed FPU timing - some sequences of FPU instructions did not calculate
939 the resource dependencies right.
941 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
942 but no FPU trap is generated.
944 version 1.7.1 31-10-95
947 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
948 the FPU stays in execute mode.
950 * Corrected JMPL and RETT timing (these instructions takes two cycles).
956 * Interrupt during annuled instruction corrupted return address - fixed.
959 version 1.6.2 25-10-95
962 * Added -DFAST_UART to Makefile
965 version 1.6.1 24-10-95
968 * Fixed bug in STDFQ which caused bus error
974 * Modified srt0.s to include code that initiates registers in IU and FPU
975 and initializes the data segment. The simulator 'load' command does not
976 longer initialize the data segment!
978 * Corrected MEC timer operation; scalers now divide the frequency by
981 * MEC breakpoints are not checked during store operation
987 * Fixed some bugs in the cycle counting for IU & FPU instructions.
989 * Fixed bug that allowed an annuled instruction to cause memory exception.
991 * The *ws parameter in mem.c should now contain the number of waitstates
992 required by the memory access (was total number of cycles).
994 * The supplied srt0.s now clears the BSS (thanks Joel).
999 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1000 some problems on solaris 2.x machines.
1002 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1003 may suffer a bit ...
1005 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1007 version 1.3 26-07-95
1008 --------------------
1010 * Fixed bug in mulscc instruction (how could that ever have worked?)
1012 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1014 version 1.2 13-07-95
1015 --------------------
1017 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1018 one interrupt pending)
1020 * Fixed updating of condition codes during logical instructions (carry and
1021 overflow were not reset)
1023 * Fixed bug in WRTBR (tt field was wrongly over-written)
1025 version 1.1 07-07-95
1026 --------------------
1028 * Fixed several bugs in the interrupt handler and callback routines.
1029 (reported by Paul Warren, Alsys)
