41 1999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
43 * exec.c (dispatch_instruction):
44 Correct the sense of the
46 sregs->trap = TRAP_UNIMP;
49 clause that has been pasted around: it's correct in the SCAN and
50 DIVScc (divide step) cases (where it was probably originally
51 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
52 ie. instructions only in the SPARC V8 or SPARClite 86x
53 architectures. It was also present when not required for SMUL,
54 SMULcc, UMUL, UMULcc instructions that are present in all
57 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
59 * interf.c (run_sim): Fix a bug in the main loop's handling of
60 annulled delay slot instructions. There is precedent for this
61 change; the _other_ main loop in sis.c gets it right according to
62 my reading of the code.
64 The bug is: if an interrupt happens when the next instruction
65 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
66 with the current values of PC and NPC, so when the trap returns,
67 the annulled instruction is indeed executed. Another giveaway is
68 that the annul flag is cleared in execute_trap(): the information
69 is demonstrably discarded.
71 The solution is: perform annulling before looking for traps, in
72 fact it's neater to do annulling, see if there's an interrupt and
73 if not, do the instruction, then handle traps be they generated by
74 interrupts pending or by the instruction we might just have done.
75 That's what the sis.c one does.
77 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
79 * sis.h: Add asr17 register for support of SparcLITE (at least the
80 Hitachi ones I find before me)
82 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
83 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
84 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
85 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
86 (init_regs): Initialize y and asr17.
87 NB: In instruction-set space, the Y register is asr0; the
88 instructions have different names for human reasons only.
91 * interf.c: Set boolean mode variable dumbio if invoked with
92 argument "-dumbio" and mention it of verbose.
93 * erc32.c: if "dumbio" is set, do not assume that there is a
94 terminal type device attached to stdin/stdout. Do not set
95 buffering or mess with tcsetattr or do any read operations in
96 order to make UART interrupts; not input data is supported.
97 This is necessary to allow the sim to be used within the eCos
98 testing infrastructure where stdin/stdout are pipes to a TCL
99 program; the sim hangs otherwise.
101 Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com>

119 Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com>
121 * interf.c (sim_open): Use revamped memory_read, which makes
122 byte-swapping unnecessary. Add -sparclite-board option for
123 emulating RAM found on typical SPARClite boards. Print
124 error message for unrecognized option.

127 (fetch_bytes, store_bytes): New helper functions for revamped
128 mememory_read and memory_write.

134 byte order instead of host byte order.

137 (memory_read): Add new sz parameter.
138 * sis.c (run_sim): Use revamped memory_read, which makes
139 byte-swapping unnecessary.

520 * SIS should now be endian independent.
525 * Fixed FPU timing - some sequences of FPU instructions did not calculate
526 the resource dependencies right.

529 but no FPU trap is generated.
531 version 1.7.1 31-10-95
534 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
535 the FPU stays in execute mode.

562 and initializes the data segment. The simulator 'load' command does not
563 longer initialize the data segment!
565 * Corrected MEC timer operation; scalers now divide the frequency by
568 * MEC breakpoints are not checked during store operation
574 * Fixed some bugs in the cycle counting for IU & FPU instructions.
576 * Fixed bug that allowed an annuled instruction to cause memory exception.
578 * The *ws parameter in mem.c should now contain the number of waitstates
579 required by the memory access (was total number of cycles).
581 * The supplied srt0.s now clears the BSS (thanks Joel).
586 * Added a '-g' switch to enable/disable the GNU readline(), which cause
587 some problems on solaris 2.x machines.
589 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
592 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
597 * Fixed bug in mulscc instruction (how could that ever have worked?)
599 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
604 * Fixed bug in interrupt handling (wrong interrupt selected when more that
605 one interrupt pending)
607 * Fixed updating of condition codes during logical instructions (carry and
608 overflow were not reset)
610 * Fixed bug in WRTBR (tt field was wrongly over-written)
615 * Fixed several bugs in the interrupt handler and callback routines.
