8 | * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak | |
9 | the frequency at which the poll_quit callback is called. | |
10 | (poll_quit_count): New global. | |
11 | (sim_io_poll_quit): Only call the poll_quit callback | |
12 | after the specified POLL_QUIT_INTERVAL. | |

16 | * dc-complex: Force expansion on all bits of field BO. | |
17 | Previously, the least-significant (prediction) bit was ignored. | |
18 | * ppc-instructions (conditional branches): Implement mpc860c0 option. | |
19 | * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option. | |
20 | * psim.c (is_num, psim_options): Added parsing for mpc860c0 option. | |
21 | * interrupts.h: Added "mpc860c0_instruction_program_interrupt". | |

26 | Make the simulator compatible with the MPC750. It would be nicer | |
27 | to make this a real multi-sim, but that's more work than we have | |
28 | time for. | |
29 | * emul_generic.c (emul_add_tree_options): Only require strict | |
30 | alignment if it was explicitly requested at configuration time. | |
31 | Don't make it the default for little-endian machines. | |
32 | * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4, | |
33 | MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1, | |
34 | THRM2, THRM3): Plop in the MPC750 SPR registers. | |
35 | (DABR): This is weird. This was HID5, but the PPC spec says this | |
36 | should be DABR; why did some random processor use it for something | |
37 | else? The HID5 entry dates back to the original checkin of the | |
38 | simulator code in 1995, so remove it. | |
39 | * sim_calls.c (register_names): Delete this; since the user can | |
40 | now change GDB's list of register names dynamically, we can't | |
41 | pretend there's a static mapping here. | |
42 | (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME | |
43 | function to get the register name. That ought to be accurate. | |
44 | However, we're changing a compile-time dependency (using the | |
45 | REGISTER_NAMES macro) into a link- and run-time dependency | |
46 | (calling REGISTER_NAME, which happens to be a function call on the | |
47 | PPC). | |
48 | ||
49 | 1999-01-22 Jim Lemke <jlemke@cygnus.com> | |
50 | ||
51 | * igen.c(gen_semantics_[ch]): setup/use of new option | |
52 | (-o mpc860c0[=n]). | |
53 | interrupts.[ch](mpc860c0_instruction_program_interrupt): added. | |
54 | ppc-instructions(the four branch insn groups): detect problematic br's. | |
55 | psim.c(is_num - added, psim_options): Parse and init new option. | |
56 | These changes are currently under #ifdef WITH_OPTION_MPC860C0. | |

67 | (sim_events_poll): Copy function from common/sim-events.c. | |
68 | (event_queue_init): Copy scheduling of sim_events_poll from same. | |
69 | ||
70 | * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function, | |
71 | poll the external environment. | |
72 | ||
73 | 1998-11-19 Michael Meissner <meissner@cygnus.com> | |
74 | ||
75 | * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the | |
76 | fractional type, so that quiet NaN's aren't treated like | |
77 | Infinities. | |
78 | ||
79 | Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com> | |
80 | ||
81 | * table.c (table_open): For cygwin hosts, we need to use the | |
82 | return value from the read routine as the number of bytes to | |
83 | process. This apparently is due to text-mode vs binary-mode. If | |
84 | the mounts are done text-mode, then the size returnedby fstat() | |
85 | may be different than the number of bytes "read" in text mode. | |

110 | Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com> | |
111 | ||
112 | * Makefile.in: The run target depended on a target psim$(EXEEXT), | |
113 | but there was no such target, only plain psim. So I changed the | |
114 | run target to depend on psim. | |
115 | ||

432 | ||
433 | * emul_chirp.c (emul_chirp_create): Handle a virtbase of -1 being | |
434 | found in the device tree. | |
435 | ||
436 | Wed Feb 5 10:56:27 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
437 | ||
438 | * Property create/initialization still wasn't correctly ordered. | |
439 | Should be delaying everything related to ihandle creation until | |
440 | after the rest of the tree has been established. | |
441 | ||
442 | * device.c (device_find_ihandle_runtime_property): Update. | |
443 | (device_add_ihandle_runtime_property): Update. | |

457 | ||
458 | * gen-icache.c: Generalize code handling XXX_is_NNN so that it | |
459 | works for normal and boolean table entries. | |
460 | ||
461 | * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now | |
462 | valid. Handle this just like *_{read,write}_register now handles | |
463 | it. | |
464 | ||
465 | Mon Feb 3 17:18:16 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |

476 | max iterations exceeded. | |
477 | ||
478 | * gen-idecode.c: Re-work the table lookup code so that it assumes | |
479 | that the entry is a leaf by default. Simplify the boolean table | |
480 | entry code so that it involves a mask + test instead of shift + | |
481 | shift + mask + test. | |
482 | ||
483 | * gen-idecode.c: Correct generated igen body so that it no drops | |
484 | or doubles clock interrupts. | |

496 | ||
497 | * configure.in (sim_callback): If the gdb is post 4.16, configure | |

510 | Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
511 | ||
512 | * igen wasn't aborting if the opcode table contained no valid | |
513 | fields. | |
514 | ||
515 | * misc.c (name2i): Possibly abort if an invalid name is | |
516 | encountered. | |

518 | ||
519 | Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
520 | ||
521 | * When performance monitoring is disabled, it is still possible to | |
522 | determine the simulation speed by looking at the number of elapsed | |
523 | ticks recorded by the event queue. | |
524 | ||
525 | * psim.c (psim_write_register, psim_read_register): Force the cpu | |
526 | to zero when it is either of `-1' or `nr_cpus'. In both cases the | |
527 | next cpu would be zero any way. | |
528 | ||
529 | * mon.c (mon_print_info): If possible, print the system cycle | |
530 | performance. This is an indication of the number of instructions | |
531 | per second. | |
532 | ||
533 | Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
534 | ||
535 | * The code to allow an event queue to be updated during a signal | |
536 | was missing. For main.c, a cntrl-c simulation termination wasn't | |
537 | handled cleanly. | |
538 | ||
539 | * The simulation would not correctly restart if an event requested | |
540 | that the simulation be halted. | |
541 | ||
542 | * psim.c (psim_options): Add hack to -i option to optionally | |
543 | include a level vis -i2. | |
544 | (psim_usage): Document. | |
545 | ||

547 | cntrl-c occures schedule an event to halt the simulation. | |
548 | (main): Catch CNTRL-C signals with the function cntrl_c. | |
549 | ||
550 | * events.c (event_queue_process): Mask interrupts while | |
551 | manipulating the async event queue. | |
552 | (event_queue_init): Ditto. | |
553 | (event_queue_schedule_after_signal): Ditto. | |
554 | ||
555 | * events.c (event_queue_process): Mark the event queue as being in | |
556 | the processing state when processing has started. Adjust code | |
557 | so that it is tolerant of halts. | |
558 | (event_queue_init): Start the event queue out with processing | |
559 | false. | |
560 | (event_queue_tick): Check that processing isn't still being | |
561 | performed. | |
562 | ||
563 | * gen-idecode.c (print_run_until_stop_body): Call | |
564 | event_queue_process_events to clear possibly pending events before | |
565 | starting a simulation run. Re-arange main loop so that simulator | |
566 | is correctly restarted when an event halts the simulation. | |
567 | ||
568 | * psim.c (psim_halt): Handle an event halting the simulation. | |
569 | * psim.c (psim_init): Adjust initial cpu - == -1 - to match | |

571 | ||
572 | Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
573 | ||
574 | * ppc-opcode-complex: Correct typo - was expanding ORA instead of | |
575 | RA. Based on instruction frequency stats, expand additional | |
576 | instructions. | |
577 | * ppc-instructions: Change all `RA == 0' to RA_is_0. | |
578 | ||
579 | * ppc-opcode-stupid: Move all but the basic table in -complex into | |
580 | here. Update to new format. | |
581 | ||
582 | * Makefile.in (tmp-defines): New target. Force defines.h to always | |
583 | be built. Hence get ppc-opcode-goto to build. | |
584 | ||
585 | Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
586 | ||
587 | * hw_com.c (hw_com_instance_read, hw_com_instance_write): | |
588 | Implement. | |
589 | ||
590 | Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
591 | ||
592 | * hw_trace.c (hw_trace_init_data): Delete. The trace options need | |
593 | to be initialized independant of the rest of the simulation | |
594 | initalization. Otherwize a trace option explictly set from gdb | |
595 | could be overridden by hw_trace. | |
596 | ||
597 | * psim.c (psim_options): Clarify reason why the trace ioctl occures. | |
598 | ||
599 | * FIXME: The trace code is too scattered - hw_trace.c, psim.c, | |
600 | debug.c. It could be much simpler. | |
601 | ||
602 | Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
603 | ||
604 | * Some devices support removable media. Add hooks to the disk | |
605 | device so that it supports this. | |
606 | ||
607 | * device.c (device_add_string_array_property, | |
608 | device_find_string_array_property): New functions, manipulate | |
609 | properties containing an array of strings. | |
610 | (device_find_string_property): Allow a string array. | |

612 | (device_init_runtime_properties): Update. | |
613 | ||
614 | * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk | |
615 | media. If no file image is specified, use the next one in the | |
616 | image property list. | |
617 | (hw_disk_init_address): Change the file property so that it is a | |
618 | string array - use the first entry for the initial file image. | |
619 | ||
620 | * tree.c (print_string_aray_property): New function - print a | |
621 | string array. | |
622 | (print_properties): Adjust. | |
623 | (print_string): Write a string, handling double quotes. | |
624 | ||
625 | * device.h: Define an ioctl to `change-media' with an optional new | |
626 | media image. | |

629 | ||
630 | * psim.c (psim_command): New function, parse more complex psim | |
631 | commands such as "change-media" and "trace". | |
632 | * sim_calls.c (sim_do_command): Use. | |
633 | ||
634 | Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
635 | ||
636 | * For expressions like (RA == 0) that are entered in to the cache | |
637 | as RA_is_0. If possible generate the result of the expression so | |
638 | that the compiler gets a better chance of eliminating dead | |
639 | branches. | |
640 | ||
641 | * gen-icache.c (print_icache_extraction): For a cache entry of | |
642 | the form <name>_is_<const> where it is a boolean field, generate | |
643 | the result of the expression instead of the expression its self. | |
644 | (print_icache_body): Remove code that was looking for *_is_0 and | |
645 | then generating corresponding definitions. | |
646 | ||
647 | * gen-icache.c (print_icache_struct): If there is no cache, do not | |
648 | output expressions in idecode.h file. | |
649 | ||
650 | * gen-icache.c (print_icache_body): Output them here. | |
651 | ||

657 | Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
658 | ||
659 | * The code that put values in and extracted values from the cache | |
660 | was too compilicated. The cache table did not allow values to be | |
661 | computed from cache entries. #defines could only be used when a | |
662 | cache was present, remove the restriction. | |
663 | ||
664 | * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A | |
665 | scratch variable is defined when a cache entry is beinf | |
666 | filled. Change the definition of a COMPUTE variable to be defined | |
667 | when the cache entry is being used. | |
668 | * gen-icache.c: Update. | |
669 | ||
670 | * ld-cache.h, ld-cache.c: Change field names so that their meaning | |
671 | is more obvious. old_name->field_name, new_name->derived_name. | |
672 | * gen-icache.c: Update | |
673 | ||
674 | * gen-icache.h, gen-icache.c (print_icache_body): Make the three | |
675 | different types of cache code - put into cache, extract from | |
676 | cache, no cache - an explicit argument to print_icache_body. | |
677 | * gen-icache.c (print_icache_extraction): Ditto. | |
678 | ||
679 | * gen-semantics.c (print_c_semantic): Update use. | |
680 | * gen-idecode.c (print_jump_insn): Update use. | |
681 | * gen-icache.c (print_icache_function): Update use. | |
682 | ||
683 | * igen.c (main): Change 'R' option so that it does not force the | |
684 | cache. | |
685 | ||
686 | * configure.in (enable-sim-icache): Clarify description. Make | |
687 | #define one of the defaults regardless of the cache. Probably | |
688 | should revamp and add a separate option. | |
689 | ||
690 | Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
691 | ||
692 | * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos | |
693 | partition numbering. | |

701 | ||
702 | * The cap object was retaining a reference to the instance of a | |
703 | device after it was deleted. Instead add and remove cap's from the | |
704 | cap db as they are created and deleted. This ensuring that a | |
705 | capibility is only used during the lifetime of the corresponding | |
706 | object. | |
707 | ||
708 | * cap.h, cap.c: Correct cap type - was signed32 should be | |
709 | signed_cell. | |
710 | ||
711 | * cap.c (cap_add, cap_remove): New methods for cap object that | |
712 | allow the explicit addition and removal of internal objects that | |
713 | the cap knows about. | |
714 | ||
715 | * cap.c (cap_init): Rewrite. Verify that the only objects | |
716 | remaining in the cap data base are those that were entered first. | |
717 | Thse objects will be the permenant ones. | |
718 | * device.c (device_init_address): Remember to initialize the cap | |
719 | database. | |
720 | ||

734 | ||
735 | * tree.c (split_device_specifier): Add support for aliases when | |
736 | looking up a device. Now needs a device as an argument. | |
737 | (split_property_specifier): Ditto. | |
738 | ||
739 | Sun Jan 19 15:28:23 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
740 | ||
741 | * The memory "claim" and "release" methods take an address and | |
742 | size as arguments. These may be multi cell values. Initially fix | |
743 | the memory code so that they check/detect this. Leave the | |
744 | adjustment of any clients to later. | |
745 | ||
746 | * hw_memory.c (hw_memory_instance_claim, | |
747 | hw_memory_instance_release): Handle multi-cell memory devices. | |

753 | ||
754 | * device.h, device.c (device_instance_call_method): Correct return | |
755 | type - can return either 0 or -1, hence should be a signed type. | |

2001 | ||
2002 | * gen-idecode.c (print_idecode_switch_illegal): Include a break | |
2003 | when generating illegal instructions. This was commented out | |
2004 | which is a hangover from looking a at switch statements generated | |
2005 | using indirect jumps. | |
2006 | ||
2007 | Tue Jul 23 20:57:01 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
2008 | ||

2014 | ||
2015 | * gen-support.c (gen_support_h): Add optional include to created | |
2016 | support.h so that, like cpu, it is optionally inlined for all | |
2017 | modules that include it. | |
2018 | * inline.h, inline.c: Adjust so that support.[hc] is handled the | |
2019 | same as cpu.[hc]. | |
2020 | ||
2021 | * idecode_fields.h (LABEL, GOTO): Macro's that create a unique | |
2022 | name for a lable and then branch to it. | |

2034 | ||
2035 | * configure.in (--enable-sim-line-nr): Typo - sim_line-nr. | |
2036 | * (--enable-sim-inline): Reorder patern matching of arguments so | |
2037 | that SUPPORT=ALL_INLINE is reconized as *=* and not *_INLINE. | |

2044 | configuration options. Let the user specify the packages or | |
2045 | hardware devices that are to be included in the build. Makes it | |
2046 | possible for user packages to be specified. | |
2047 | ||
2048 | * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and | |
2049 | hardware instead of checking it using ls. configure.in should | |
2050 | have taken care of any problems. | |
2051 | (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure. | |
2052 | ||

2060 | ||
2061 | * configure.in (icache): Extend icache flag to include an insn | |
2062 | option. If specifyed the insn - aka instruction - is included in | |

2065 | ||
2066 | * igen.c (main), igen.h: Add option -S - inSn - for specifying | |

2090 | ||
2091 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
2092 | ||
2093 | * gen-idecode.c: Output the complete run_until_stop function | |
2094 | instead of just the code to handle a single instruction issue. | |
2095 | * : Have the generated idecode.c include inline.c (instead of psim.c). | |
2096 | ||
2097 | * std-config.h: Change psim.c so that it isn't inlined (as this is | |
2098 | no longer needed). | |
2099 | ||
2100 | * psim.c (run_until_stop): Delete the old run_until_stop function | |
2101 | instead calling the idecode_run and idecode_run_until_stop | |
2102 | functions that gen-idecode.c is now creating. | |
2103 | ||
2104 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |

2129 | corresponding call to ITRACE so that it still matches. | |
2130 | ||
2131 | * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead | |
2132 | of ITRACE. The CPP line directives would have previously set the | |
2133 | line-nr and file name so ITRACE isn't needed. | |

2138 | idecode generation option. Instead of generating and calling | |
2139 | separate functions containing the semantic and icache code | |
2140 | generate a single monolythic function and use goto's (and GCC's | |
2141 | indirect jump) to move between code blocks. | |
2142 | ||
2143 | * Makefile.in: Add sim_jump flag to those passed to igen. | |
2144 | ||
2145 | * configure.in: New option --enable-sim-jump (default disabled) | |
2146 | ||

2151 | * ppc-opcode-jump: New file. Set of opcode rules useful when | |
2152 | testing jumping idecodes. | |

2160 | decode functions. | |
2161 | ||
2162 | * configure.in (--enable-sim-icache): Accept an option list such | |
2163 | as 1024,define. Add a new choice to the list - semantic - which | |
2164 | will cause igen to generate instruction decode functions that | |
2165 | include the corresponding semantic code. | |
2166 | ||
2167 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |

2183 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
2184 | ||
2185 | * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so | |
2186 | that they use the same technique as igen (ie a dummy targets | |
2187 | tmp-pk and tmp-hw are created). | |
2188 | ||
2189 | Mon Jun 24 22:28:00 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
