58
59 1999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
60
61 * exec.c (dispatch_instruction):
62 Correct the sense of the
63 if (!sparclite) {
64 sregs->trap = TRAP_UNIMP;
65 break;
66 }
67 clause that has been pasted around: it's correct in the SCAN and
68 DIVScc (divide step) cases (where it was probably originally
69 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
70 ie. instructions only in the SPARC V8 or SPARClite 86x
71 architectures. It was also present when not required for SMUL,
72 SMULcc, UMUL, UMULcc instructions that are present in all
73 architectures.
74
75 1999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
76
77 * interf.c (run_sim): Fix a bug in the main loop's handling of
78 annulled delay slot instructions. There is precedent for this
79 change; the _other_ main loop in sis.c gets it right according to
80 my reading of the code.
81
82 The bug is: if an interrupt happens when the next instruction
83 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
84 with the current values of PC and NPC, so when the trap returns,
85 the annulled instruction is indeed executed. Another giveaway is
86 that the annul flag is cleared in execute_trap(): the information
87 is demonstrably discarded.
88
89 The solution is: perform annulling before looking for traps, in
90 fact it's neater to do annulling, see if there's an interrupt and
91 if not, do the instruction, then handle traps be they generated by
92 interrupts pending or by the instruction we might just have done.
93 That's what the sis.c one does.
94
95 1999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
96
97 * sis.h: Add asr17 register for support of SparcLITE (at least the
98 Hitachi ones I find before me)
99
100 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
101 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
102 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
103 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
104 (init_regs): Initialize y and asr17.
105 NB: In instruction-set space, the Y register is asr0; the
106 instructions have different names for human reasons only.
107
108 * sis.c:
109 * interf.c: Set boolean mode variable dumbio if invoked with
110 argument "-dumbio" and mention it of verbose.
111 * erc32.c: if "dumbio" is set, do not assume that there is a
112 terminal type device attached to stdin/stdout. Do not set
113 buffering or mess with tcsetattr or do any read operations in
114 order to make UART interrupts; not input data is supported.
115 This is necessary to allow the sim to be used within the eCos
116 testing infrastructure where stdin/stdout are pipes to a TCL
117 program; the sim hangs otherwise.
118
119 Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com>
120
121 * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.

135 is greater then 2.
136
137 Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com>
138
139 * interf.c (sim_open): Use revamped memory_read, which makes
140 byte-swapping unnecessary. Add -sparclite-board option for
141 emulating RAM found on typical SPARClite boards. Print
142 error message for unrecognized option.
143 * erc32.c: Change RAM address and size from constants to variables,
144 to allow emulation of SPARClite board RAM.
145 (fetch_bytes, store_bytes): New helper functions for revamped
146 mememory_read and memory_write.
147 (memory_read, memory_write): Rewrite to store bytes in target
148 byte order instead of storing words in host byte order; this
149 greatly simplifies support of little-endian programs.
150 (get_mem_ptr): Remove unnecessary byte parameter.
151 (sis_memory_write, sis_memory_read): Store words in target
152 byte order instead of host byte order.

154 * sis.h ((byte_swap_words): Remove declaration, no longer needed.
155 (memory_read): Add new sz parameter.
156 * sis.c (run_sim): Use revamped memory_read, which makes
157 byte-swapping unnecessary.
158 * exec.c (dispatch_instruction): Use revamped memory_read, which
159 makes byte-swapping and double-word fetching unnecessary.
160 * func.c (sparclite_board): Declare new variable.
161 (get_regi): Handle little-endian data.
162 (bfd_load): Recognize little-endian SPARClite as having
163 little-endian data.

465 Sun Sep 8 14:04:37 1996 Stu Grossman (grossman@critters.cygnus.com)
466
467 * erc32.c (port_init): Disable this for __GO32__ (got no pty's
468 there either...).
469
470 Mon Aug 12 17:04:58 1996 Stu Grossman (grossman@critters.cygnus.com)
471
472 * erc32.c: Don't include sys/ioctl.h or sys/file.h. They aren't
473 necessary.
474 * (port_init): Don't even *try* to open pty's under _WIN32.
475 * Use SIM_ADDR, not caddr_t for declaring vars that hold addresses.
476 * float.c: Get rid of #warning. Makes Microsoft C barf.
477 * interf.c (sim_open): Cast fprintf to (fprintf_ftype) to fix
478 compiler warning.
479 * (sim_load sim_create_inferior sim_read): Use prototypes only in
480 decls, not defs.
481 * Get rid of enum sim_stop. It's defined in remote-sim.h.

483 * sis.h: Include ansidecl.h and remote-sim.h.
484
485 Wed Jul 3 16:05:23 1996 Stu Grossman (grossman@critters.cygnus.com)
486
487 * erc32.c (mec_reset mec_read mec_write memory_read memory_write),
488 sis.h: Get rid of all uses of long long's.
489 * (close_port read_uart write_uart uarta_tx): Don't seg fault
490 when can't open pty's.
491 * exec.c: Add two new instructions: smul, and divscc.
492 * interf.c (flush_windows): New routine to flush the register
493 windows out to the stack just before returning to GDB. Makes
494 backtraces work much better.
495

497
498 * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir,
499 INSTALL_PROGRAM, INSTALL_DATA): Use autoconf-set values.

506
507 * configure.in: Call AC_PROG_CC before running configure.host.
508 * configure: Rebuild with autoconf 2.10.
509
510 Tue Jun 4 10:37:12 1996 Tom Tromey <tromey@csk3.cygnus.com>
511
512 * Makefile.in (install): Don't check to see if tooldir exists.
513 Make $(tooldir) and $(tooldir)/bin.
514
515 Mon Jun 3 12:33:38 1996 Ian Lance Taylor <ian@cygnus.com>
516
517 * Makefile.in (end.h): Use explicit ./ when running end.
518
519 Sun May 19 21:05:31 1996 Rob Savoye <rob@chinadoll.cygnus.com>
520
521 * func.c(bfd_load): Don't try to print the filename if the pfbd is
522 NULL.
523 * interf.c(sim_load): Pass the whole string, not just the first
524 byte.
525
526 Version 2.1 26-02-96
527 --------------------
528
529 * Fixed bug in "go" command.
530
531 version 2.0 05-02-96
532 --------------------
533
534 * Fixed bug in interrupt force register (erc32.c).
535
536 * Change file load function to use bfd_openr.
537
538 * SIS should now be endian independent.
539
540 version 1.8 24-11-95
541 --------------------
542
543 * Fixed FPU timing - some sequences of FPU instructions did not calculate
544 the resource dependencies right.
545
546 * Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
547 but no FPU trap is generated.
548
549 version 1.7.1 31-10-95
550 --------------------
551
552 * Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
553 the FPU stays in execute mode.
554
555 * Corrected JMPL and RETT timing (these instructions takes two cycles).
556
557
558 version 1.7 25-10-95
559 --------------------
560
561 * Interrupt during annuled instruction corrupted return address - fixed.
562
563
564 version 1.6.2 25-10-95
565 --------------------
566
567 * Added -DFAST_UART to Makefile
568
569
570 version 1.6.1 24-10-95
571 --------------------
572
573 * Fixed bug in STDFQ which caused bus error
574
575
576 version 1.6 02-10-95
577 --------------------
578
579 * Modified srt0.s to include code that initiates registers in IU and FPU
580 and initializes the data segment. The simulator 'load' command does not
581 longer initialize the data segment!
582
583 * Corrected MEC timer operation; scalers now divide the frequency by
584 (scaler_value + 1).
585
586 * MEC breakpoints are not checked during store operation
587
588
589 version 1.5 14-09-95
590 --------------------
591
592 * Fixed some bugs in the cycle counting for IU & FPU instructions.
593
594 * Fixed bug that allowed an annuled instruction to cause memory exception.
595
596 * The *ws parameter in mem.c should now contain the number of waitstates
597 required by the memory access (was total number of cycles).
598
599 * The supplied srt0.s now clears the BSS (thanks Joel).
600
601 version 1.4 22-08-95
602 --------------------
603
604 * Added a '-g' switch to enable/disable the GNU readline(), which cause
605 some problems on solaris 2.x machines.
606
607 * Enabled MEC watchpoint and breakpoint function to mem.c. Performance
608 may suffer a bit ...
609
610 NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
611
612 version 1.3 26-07-95
613 --------------------
614
615 * Fixed bug in mulscc instruction (how could that ever have worked?)
616
617 * Fixed bug in UART B (flushed characters on UART A), thanks Paul.
618
619 version 1.2 13-07-95
620 --------------------
621
622 * Fixed bug in interrupt handling (wrong interrupt selected when more that
623 one interrupt pending)
624
625 * Fixed updating of condition codes during logical instructions (carry and
626 overflow were not reset)
627
628 * Fixed bug in WRTBR (tt field was wrongly over-written)
629
630 version 1.1 07-07-95
631 --------------------
632
633 * Fixed several bugs in the interrupt handler and callback routines.
634 (reported by Paul Warren, Alsys)
