423 1999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
425 * exec.c (dispatch_instruction):
426 Correct the sense of the
428 sregs->trap = TRAP_UNIMP;
431 clause that has been pasted around: it's correct in the SCAN and
432 DIVScc (divide step) cases (where it was probably originally
433 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
434 ie. instructions only in the SPARC V8 or SPARClite 86x
435 architectures. It was also present when not required for SMUL,
436 SMULcc, UMUL, UMULcc instructions that are present in all
439 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
441 * interf.c (run_sim): Fix a bug in the main loop's handling of
442 annulled delay slot instructions. There is precedent for this
443 change; the _other_ main loop in sis.c gets it right according to
444 my reading of the code.
446 The bug is: if an interrupt happens when the next instruction
447 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
448 with the current values of PC and NPC, so when the trap returns,
449 the annulled instruction is indeed executed. Another giveaway is
450 that the annul flag is cleared in execute_trap(): the information
451 is demonstrably discarded.
453 The solution is: perform annulling before looking for traps, in
454 fact it's neater to do annulling, see if there's an interrupt and
455 if not, do the instruction, then handle traps be they generated by
456 interrupts pending or by the instruction we might just have done.
457 That's what the sis.c one does.
459 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
461 * sis.h: Add asr17 register for support of SparcLITE (at least the
462 Hitachi ones I find before me)
464 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
465 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
466 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
467 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
468 (init_regs): Initialize y and asr17.
469 NB: In instruction-set space, the Y register is asr0; the
470 instructions have different names for human reasons only.
473 * interf.c: Set boolean mode variable dumbio if invoked with
474 argument "-dumbio" and mention it of verbose.
475 * erc32.c: if "dumbio" is set, do not assume that there is a
476 terminal type device attached to stdin/stdout. Do not set
477 buffering or mess with tcsetattr or do any read operations in
478 order to make UART interrupts; not input data is supported.
479 This is necessary to allow the sim to be used within the eCos
480 testing infrastructure where stdin/stdout are pipes to a TCL
481 program; the sim hangs otherwise.

887 * interf.c(sim_load): Pass the whole string, not just the first
893 * Fixed bug in "go" command.
898 * Fixed bug in interrupt force register (erc32.c).
900 * Change file load function to use bfd_openr.
902 * SIS should now be endian independent.
907 * Fixed FPU timing - some sequences of FPU instructions did not calculate
908 the resource dependencies right.
910 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
911 but no FPU trap is generated.
913 version 1.7.1 31-10-95
916 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
917 the FPU stays in execute mode.
919 * Corrected JMPL and RETT timing (these instructions takes two cycles).
925 * Interrupt during annuled instruction corrupted return address - fixed.
928 version 1.6.2 25-10-95
931 * Added -DFAST_UART to Makefile
934 version 1.6.1 24-10-95
937 * Fixed bug in STDFQ which caused bus error
943 * Modified srt0.s to include code that initiates registers in IU and FPU
944 and initializes the data segment. The simulator 'load' command does not
945 longer initialize the data segment!
947 * Corrected MEC timer operation; scalers now divide the frequency by
950 * MEC breakpoints are not checked during store operation
956 * Fixed some bugs in the cycle counting for IU & FPU instructions.
958 * Fixed bug that allowed an annuled instruction to cause memory exception.
960 * The *ws parameter in mem.c should now contain the number of waitstates
961 required by the memory access (was total number of cycles).
963 * The supplied srt0.s now clears the BSS (thanks Joel).
968 * Added a '-g' switch to enable/disable the GNU readline(), which cause
969 some problems on solaris 2.x machines.
971 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
974 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
979 * Fixed bug in mulscc instruction (how could that ever have worked?)
981 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
986 * Fixed bug in interrupt handling (wrong interrupt selected when more that
987 one interrupt pending)
989 * Fixed updating of condition codes during logical instructions (carry and
990 overflow were not reset)
992 * Fixed bug in WRTBR (tt field was wrongly over-written)
997 * Fixed several bugs in the interrupt handler and callback routines.
998 (reported by Paul Warren, Alsys)
