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

546 * interf.c (sim_open): Use revamped memory_read, which makes
547 byte-swapping unnecessary. Add -sparclite-board option for
548 emulating RAM found on typical SPARClite boards. Print

552 (fetch_bytes, store_bytes): New helper functions for revamped
553 mememory_read and memory_write.

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

930 * interf.c(sim_load): Pass the whole string, not just the first
936 * Fixed bug in "go" command.
941 * Fixed bug in interrupt force register (erc32.c).
943 * Change file load function to use bfd_openr.
945 * SIS should now be endian independent.
950 * Fixed FPU timing - some sequences of FPU instructions did not calculate
951 the resource dependencies right.
953 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
954 but no FPU trap is generated.
956 version 1.7.1 31-10-95
959 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
960 the FPU stays in execute mode.
962 * Corrected JMPL and RETT timing (these instructions takes two cycles).
968 * Interrupt during annuled instruction corrupted return address - fixed.
971 version 1.6.2 25-10-95
974 * Added -DFAST_UART to Makefile
977 version 1.6.1 24-10-95
980 * Fixed bug in STDFQ which caused bus error
986 * Modified srt0.s to include code that initiates registers in IU and FPU
987 and initializes the data segment. The simulator 'load' command does not
988 longer initialize the data segment!
990 * Corrected MEC timer operation; scalers now divide the frequency by
993 * MEC breakpoints are not checked during store operation
999 * Fixed some bugs in the cycle counting for IU & FPU instructions.
1001 * Fixed bug that allowed an annuled instruction to cause memory exception.
1003 * The *ws parameter in mem.c should now contain the number of waitstates
1004 required by the memory access (was total number of cycles).
1006 * The supplied srt0.s now clears the BSS (thanks Joel).
1008 version 1.4 22-08-95
1009 --------------------
1011 * Added a '-g' switch to enable/disable the GNU readline(), which cause
1012 some problems on solaris 2.x machines.
1014 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
1015 may suffer a bit ...
1017 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
1019 version 1.3 26-07-95
1020 --------------------
1022 * Fixed bug in mulscc instruction (how could that ever have worked?)
1024 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
1026 version 1.2 13-07-95
1027 --------------------
1029 * Fixed bug in interrupt handling (wrong interrupt selected when more that
1030 one interrupt pending)
1032 * Fixed updating of condition codes during logical instructions (carry and
1033 overflow were not reset)
1035 * Fixed bug in WRTBR (tt field was wrongly over-written)
1037 version 1.1 07-07-95
1038 --------------------
1040 * Fixed several bugs in the interrupt handler and callback routines.
1041 (reported by Paul Warren, Alsys)
