397 1999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
399 * exec.c (dispatch_instruction):
400 Correct the sense of the
402 sregs->trap = TRAP_UNIMP;
405 clause that has been pasted around: it's correct in the SCAN and
406 DIVScc (divide step) cases (where it was probably originally
407 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
408 ie. instructions only in the SPARC V8 or SPARClite 86x
409 architectures. It was also present when not required for SMUL,
410 SMULcc, UMUL, UMULcc instructions that are present in all
413 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
415 * interf.c (run_sim): Fix a bug in the main loop's handling of
416 annulled delay slot instructions. There is precedent for this
417 change; the _other_ main loop in sis.c gets it right according to
418 my reading of the code.
420 The bug is: if an interrupt happens when the next instruction
421 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
422 with the current values of PC and NPC, so when the trap returns,
423 the annulled instruction is indeed executed. Another giveaway is
424 that the annul flag is cleared in execute_trap(): the information
425 is demonstrably discarded.
427 The solution is: perform annulling before looking for traps, in
428 fact it's neater to do annulling, see if there's an interrupt and
429 if not, do the instruction, then handle traps be they generated by
430 interrupts pending or by the instruction we might just have done.
431 That's what the sis.c one does.
433 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
435 * sis.h: Add asr17 register for support of SparcLITE (at least the
436 Hitachi ones I find before me)
438 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
439 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
440 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
441 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
442 (init_regs): Initialize y and asr17.
443 NB: In instruction-set space, the Y register is asr0; the
444 instructions have different names for human reasons only.
447 * interf.c: Set boolean mode variable dumbio if invoked with
448 argument "-dumbio" and mention it of verbose.
449 * erc32.c: if "dumbio" is set, do not assume that there is a
450 terminal type device attached to stdin/stdout. Do not set
451 buffering or mess with tcsetattr or do any read operations in
452 order to make UART interrupts; not input data is supported.
453 This is necessary to allow the sim to be used within the eCos
454 testing infrastructure where stdin/stdout are pipes to a TCL
455 program; the sim hangs otherwise.

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

482 to allow emulation of SPARClite board RAM.
483 (fetch_bytes, store_bytes): New helper functions for revamped
484 mememory_read and memory_write.

495 byte-swapping unnecessary.
496 * exec.c (dispatch_instruction): Use revamped memory_read, which

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