37 1999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
39 * exec.c (dispatch_instruction):
40 Correct the sense of the
42 sregs->trap = TRAP_UNIMP;
45 clause that has been pasted around: it's correct in the SCAN and
46 DIVScc (divide step) cases (where it was probably originally
47 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
48 ie. instructions only in the SPARC V8 or SPARClite 86x
49 architectures. It was also present when not required for SMUL,
50 SMULcc, UMUL, UMULcc instructions that are present in all
53 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
55 * interf.c (run_sim): Fix a bug in the main loop's handling of
56 annulled delay slot instructions. There is precedent for this
57 change; the _other_ main loop in sis.c gets it right according to
58 my reading of the code.
60 The bug is: if an interrupt happens when the next instruction
61 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
62 with the current values of PC and NPC, so when the trap returns,
63 the annulled instruction is indeed executed. Another giveaway is
64 that the annul flag is cleared in execute_trap(): the information
65 is demonstrably discarded.
67 The solution is: perform annulling before looking for traps, in
68 fact it's neater to do annulling, see if there's an interrupt and
69 if not, do the instruction, then handle traps be they generated by
70 interrupts pending or by the instruction we might just have done.
71 That's what the sis.c one does.
73 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
75 * sis.h: Add asr17 register for support of SparcLITE (at least the
76 Hitachi ones I find before me)
78 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
79 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
80 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
81 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
82 (init_regs): Initialize y and asr17.
83 NB: In instruction-set space, the Y register is asr0; the
84 instructions have different names for human reasons only.
87 * interf.c: Set boolean mode variable dumbio if invoked with
88 argument "-dumbio" and mention it of verbose.
89 * erc32.c: if "dumbio" is set, do not assume that there is a
90 terminal type device attached to stdin/stdout. Do not set
91 buffering or mess with tcsetattr or do any read operations in
92 order to make UART interrupts; not input data is supported.
93 This is necessary to allow the sim to be used within the eCos
94 testing infrastructure where stdin/stdout are pipes to a TCL
95 program; the sim hangs otherwise.
97 Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com>

115 Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com>
117 * interf.c (sim_open): Use revamped memory_read, which makes
118 byte-swapping unnecessary. Add -sparclite-board option for
119 emulating RAM found on typical SPARClite boards. Print
120 error message for unrecognized option.
121 * erc32.c: Change RAM address and size from constants to variables,
122 to allow emulation of SPARClite board RAM.
123 (fetch_bytes, store_bytes): New helper functions for revamped
124 mememory_read and memory_write.
125 (memory_read, memory_write): Rewrite to store bytes in target
126 byte order instead of storing words in host byte order; this
127 greatly simplifies support of little-endian programs.

129 (sis_memory_write, sis_memory_read): Store words in target
130 byte order instead of host byte order.

132 * sis.h ((byte_swap_words): Remove declaration, no longer needed.
133 (memory_read): Add new sz parameter.
134 * sis.c (run_sim): Use revamped memory_read, which makes
135 byte-swapping unnecessary.
136 * exec.c (dispatch_instruction): Use revamped memory_read, which
137 makes byte-swapping and double-word fetching unnecessary.

507 * Fixed bug in "go" command.
512 * Fixed bug in interrupt force register (erc32.c).
514 * Change file load function to use bfd_openr.
516 * SIS should now be endian independent.
521 * Fixed FPU timing - some sequences of FPU instructions did not calculate
522 the resource dependencies right.
524 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
525 but no FPU trap is generated.
527 version 1.7.1 31-10-95
530 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
531 the FPU stays in execute mode.
533 * Corrected JMPL and RETT timing (these instructions takes two cycles).
539 * Interrupt during annuled instruction corrupted return address - fixed.
542 version 1.6.2 25-10-95

548 version 1.6.1 24-10-95
551 * Fixed bug in STDFQ which caused bus error
557 * Modified srt0.s to include code that initiates registers in IU and FPU
558 and initializes the data segment. The simulator 'load' command does not
559 longer initialize the data segment!
561 * Corrected MEC timer operation; scalers now divide the frequency by
564 * MEC breakpoints are not checked during store operation
570 * Fixed some bugs in the cycle counting for IU & FPU instructions.
572 * Fixed bug that allowed an annuled instruction to cause memory exception.
574 * The *ws parameter in mem.c should now contain the number of waitstates
575 required by the memory access (was total number of cycles).
577 * The supplied srt0.s now clears the BSS (thanks Joel).
582 * Added a '-g' switch to enable/disable the GNU readline(), which cause
583 some problems on solaris 2.x machines.
585 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
588 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
593 * Fixed bug in mulscc instruction (how could that ever have worked?)
595 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
600 * Fixed bug in interrupt handling (wrong interrupt selected when more that
601 one interrupt pending)
603 * Fixed updating of condition codes during logical instructions (carry and
604 overflow were not reset)
606 * Fixed bug in WRTBR (tt field was wrongly over-written)
611 * Fixed several bugs in the interrupt handler and callback routines.
