57 | Make the simulator compatible with the MPC750. It would be nicer | |
58 | to make this a real multi-sim, but that's more work than we have | |
59 | time for. | |
60 | * emul_generic.c (emul_add_tree_options): Only require strict | |
61 | alignment if it was explicitly requested at configuration time. | |
62 | Don't make it the default for little-endian machines. | |
63 | * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4, | |
64 | MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1, | |
65 | THRM2, THRM3): Plop in the MPC750 SPR registers. | |
66 | (DABR): This is weird. This was HID5, but the PPC spec says this | |
67 | should be DABR; why did some random processor use it for something | |
68 | else? The HID5 entry dates back to the original checkin of the | |
69 | simulator code in 1995, so remove it. | |
70 | * sim_calls.c (register_names): Delete this; since the user can | |
71 | now change GDB's list of register names dynamically, we can't | |
72 | pretend there's a static mapping here. | |
73 | (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME | |
74 | function to get the register name. That ought to be accurate. | |
75 | However, we're changing a compile-time dependency (using the | |
76 | REGISTER_NAMES macro) into a link- and run-time dependency | |
77 | (calling REGISTER_NAME, which happens to be a function call on the | |
78 | PPC). | |
79 | ||
80 | 1999-01-22 Jim Lemke <jlemke@cygnus.com> | |
81 | ||
82 | * igen.c(gen_semantics_[ch]): setup/use of new option | |
83 | (-o mpc860c0[=n]). | |
84 | interrupts.[ch](mpc860c0_instruction_program_interrupt): added. | |
85 | ppc-instructions(the four branch insn groups): detect problematic br's. | |
86 | psim.c(is_num - added, psim_options): Parse and init new option. | |
87 | These changes are currently under #ifdef WITH_OPTION_MPC860C0. | |

99 | (event_queue_init): Copy scheduling of sim_events_poll from same. | |
100 | ||
101 | * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function, | |
102 | poll the external environment. | |
103 | ||
104 | 1998-11-19 Michael Meissner <meissner@cygnus.com> | |

106 | * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the | |
107 | fractional type, so that quiet NaN's aren't treated like | |
108 | Infinities. | |
109 | ||
110 | Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com> | |
111 | ||
112 | * table.c (table_open): For cygwin hosts, we need to use the | |
113 | return value from the read routine as the number of bytes to | |
114 | process. This apparently is due to text-mode vs binary-mode. If | |
115 | the mounts are done text-mode, then the size returnedby fstat() | |
116 | may be different than the number of bytes "read" in text mode. | |

141 | Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com> | |
142 | ||
143 | * Makefile.in: The run target depended on a target psim$(EXEEXT), | |
144 | but there was no such target, only plain psim. So I changed the | |
145 | run target to depend on psim. | |
146 | ||

422 | ||
423 | * Many of the ppc-opcode-* files are identical baring the type of | |
424 | lookup table. Instead of having multiple tables, igen can do this | |
425 | via an additional option. | |
426 | ||
427 | * ld-decode.h, ld-decode.c (force_decode_gen_type): New function, | |
428 | allow the type of generated table specified in the decode file to | |

463 | ||
464 | * emul_chirp.c (emul_chirp_create): Handle a virtbase of -1 being | |
465 | found in the device tree. | |
466 | ||
467 | Wed Feb 5 10:56:27 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
468 | ||
469 | * Property create/initialization still wasn't correctly ordered. | |
470 | Should be delaying everything related to ihandle creation until | |
471 | after the rest of the tree has been established. | |
472 | ||
473 | * device.c (device_find_ihandle_runtime_property): Update. | |
474 | (device_add_ihandle_runtime_property): Update. | |

481 | ||
482 | * gen-icache.c (print_icache_extraction): Add a reason parameter. | |
483 | Augment each extracted field with a comment citing the codes | |
484 | origin. Should simplify tracking down incorrect cache | |

488 | ||
489 | * gen-icache.c: Generalize code handling XXX_is_NNN so that it | |
490 | works for normal and boolean table entries. | |
491 | ||
492 | * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now | |
493 | valid. Handle this just like *_{read,write}_register now handles | |
494 | it. | |
495 | ||
496 | Mon Feb 3 17:18:16 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |

507 | max iterations exceeded. | |
508 | ||
509 | * gen-idecode.c: Re-work the table lookup code so that it assumes | |
510 | that the entry is a leaf by default. Simplify the boolean table | |
511 | entry code so that it involves a mask + test instead of shift + | |
512 | shift + mask + test. | |
513 | ||
514 | * gen-idecode.c: Correct generated igen body so that it no drops | |
515 | or doubles clock interrupts. | |

524 | if common callback is present. | |
525 | ||
526 | Wed Jan 29 12:32:41 1997 Michael Meissner <meissner@tiktok.cygnus.com> | |
527 | ||
528 | * configure.in (sim_callback): If the gdb is post 4.16, configure | |

541 | Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
542 | ||
543 | * igen wasn't aborting if the opcode table contained no valid | |
544 | fields. | |
545 | ||
546 | * misc.c (name2i): Possibly abort if an invalid name is | |
547 | encountered. | |
548 | * ld-decode.c: Abort if the table type isn't found. | |
549 | ||
550 | Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
551 | ||
552 | * When performance monitoring is disabled, it is still possible to | |
553 | determine the simulation speed by looking at the number of elapsed | |
554 | ticks recorded by the event queue. | |
555 | ||
556 | * psim.c (psim_write_register, psim_read_register): Force the cpu | |
557 | to zero when it is either of `-1' or `nr_cpus'. In both cases the | |
558 | next cpu would be zero any way. | |
559 | ||
560 | * mon.c (mon_print_info): If possible, print the system cycle | |
561 | performance. This is an indication of the number of instructions | |
562 | per second. | |
563 | ||
564 | Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
565 | ||
566 | * The code to allow an event queue to be updated during a signal | |
567 | was missing. For main.c, a cntrl-c simulation termination wasn't | |
568 | handled cleanly. | |
569 | ||
570 | * The simulation would not correctly restart if an event requested | |
571 | that the simulation be halted. | |
572 | ||
573 | * psim.c (psim_options): Add hack to -i option to optionally | |
574 | include a level vis -i2. | |
575 | (psim_usage): Document. | |
576 | ||
577 | * main.c (cntrl_c, cntrl_c_simulation): New functions. When a | |
578 | cntrl-c occures schedule an event to halt the simulation. | |
579 | (main): Catch CNTRL-C signals with the function cntrl_c. | |
580 | ||
581 | * events.c (event_queue_process): Mask interrupts while | |
582 | manipulating the async event queue. | |
583 | (event_queue_init): Ditto. | |
584 | (event_queue_schedule_after_signal): Ditto. | |
585 | ||
586 | * events.c (event_queue_process): Mark the event queue as being in | |
587 | the processing state when processing has started. Adjust code | |
588 | so that it is tolerant of halts. | |
589 | (event_queue_init): Start the event queue out with processing | |
590 | false. | |
591 | (event_queue_tick): Check that processing isn't still being | |
592 | performed. | |
593 | ||
594 | * gen-idecode.c (print_run_until_stop_body): Call | |
595 | event_queue_process_events to clear possibly pending events before | |
596 | starting a simulation run. Re-arange main loop so that simulator | |
597 | is correctly restarted when an event halts the simulation. | |
598 | ||
599 | * psim.c (psim_halt): Handle an event halting the simulation. | |
600 | * psim.c (psim_init): Adjust initial cpu - == -1 - to match | |
601 | reworked idecode. | |
602 | ||
603 | Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
604 | ||
605 | * ppc-opcode-complex: Correct typo - was expanding ORA instead of | |
606 | RA. Based on instruction frequency stats, expand additional | |
607 | instructions. | |
608 | * ppc-instructions: Change all `RA == 0' to RA_is_0. | |
609 | ||
610 | * ppc-opcode-stupid: Move all but the basic table in -complex into | |
611 | here. Update to new format. | |
612 | ||
613 | * Makefile.in (tmp-defines): New target. Force defines.h to always | |
614 | be built. Hence get ppc-opcode-goto to build. | |
615 | ||
616 | Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
617 | ||
618 | * hw_com.c (hw_com_instance_read, hw_com_instance_write): | |
619 | Implement. | |
620 | ||
621 | Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
622 | ||
623 | * hw_trace.c (hw_trace_init_data): Delete. The trace options need | |
624 | to be initialized independant of the rest of the simulation | |
625 | initalization. Otherwize a trace option explictly set from gdb | |
626 | could be overridden by hw_trace. | |
627 | ||
628 | * psim.c (psim_options): Clarify reason why the trace ioctl occures. | |
629 | ||
630 | * FIXME: The trace code is too scattered - hw_trace.c, psim.c, | |
631 | debug.c. It could be much simpler. | |
632 | ||
633 | Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
634 | ||
635 | * Some devices support removable media. Add hooks to the disk | |
636 | device so that it supports this. | |
637 | ||
638 | * device.c (device_add_string_array_property, | |
639 | device_find_string_array_property): New functions, manipulate | |
640 | properties containing an array of strings. | |
641 | (device_find_string_property): Allow a string array. | |
642 | (device_init_static_properties): Update. | |
643 | (device_init_runtime_properties): Update. | |
644 | ||
645 | * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk | |
646 | media. If no file image is specified, use the next one in the | |
647 | image property list. | |
648 | (hw_disk_init_address): Change the file property so that it is a | |
649 | string array - use the first entry for the initial file image. | |
650 | ||
651 | * tree.c (print_string_aray_property): New function - print a | |
652 | string array. | |
653 | (print_properties): Adjust. | |
654 | (print_string): Write a string, handling double quotes. | |
655 | ||
656 | * device.h: Define an ioctl to `change-media' with an optional new | |
657 | media image. | |
658 | ||
659 | * hw_disk.c: Allow floppy disk devices to be specified. | |
660 | ||
661 | * psim.c (psim_command): New function, parse more complex psim | |
662 | commands such as "change-media" and "trace". | |
663 | * sim_calls.c (sim_do_command): Use. | |
664 | ||
665 | Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
666 | ||
667 | * For expressions like (RA == 0) that are entered in to the cache | |
668 | as RA_is_0. If possible generate the result of the expression so | |
669 | that the compiler gets a better chance of eliminating dead | |
670 | branches. | |
671 | ||
672 | * gen-icache.c (print_icache_extraction): For a cache entry of | |
673 | the form <name>_is_<const> where it is a boolean field, generate | |
674 | the result of the expression instead of the expression its self. | |
675 | (print_icache_body): Remove code that was looking for *_is_0 and | |
676 | then generating corresponding definitions. | |
677 | ||
678 | * gen-icache.c (print_icache_struct): If there is no cache, do not | |
679 | output expressions in idecode.h file. | |
680 | ||
681 | * gen-icache.c (print_icache_body): Output them here. | |
682 | ||
683 | * ppc-opcode-complex: Clarify constant values for SPR==LR register | |
684 | expansion. | |

687 | ||
688 | Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
689 | ||
690 | * The code that put values in and extracted values from the cache | |
691 | was too compilicated. The cache table did not allow values to be | |
692 | computed from cache entries. #defines could only be used when a | |
693 | cache was present, remove the restriction. | |
694 | ||
695 | * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A | |
696 | scratch variable is defined when a cache entry is beinf | |
697 | filled. Change the definition of a COMPUTE variable to be defined | |
698 | when the cache entry is being used. | |
699 | * gen-icache.c: Update. | |
700 | ||
701 | * ld-cache.h, ld-cache.c: Change field names so that their meaning | |
702 | is more obvious. old_name->field_name, new_name->derived_name. | |
703 | * gen-icache.c: Update | |
704 | ||
705 | * gen-icache.h, gen-icache.c (print_icache_body): Make the three | |
706 | different types of cache code - put into cache, extract from | |
707 | cache, no cache - an explicit argument to print_icache_body. | |
708 | * gen-icache.c (print_icache_extraction): Ditto. | |
709 | ||
710 | * gen-semantics.c (print_c_semantic): Update use. | |
711 | * gen-idecode.c (print_jump_insn): Update use. | |
712 | * gen-icache.c (print_icache_function): Update use. | |
713 | ||
714 | * igen.c (main): Change 'R' option so that it does not force the | |
715 | cache. | |
716 | ||
717 | * configure.in (enable-sim-icache): Clarify description. Make | |
718 | #define one of the defaults regardless of the cache. Probably | |
719 | should revamp and add a separate option. | |
720 | ||
721 | Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
722 | ||
723 | * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos | |
724 | partition numbering. | |
725 | (pk_disklabel_create_instance): Partition 1..4 are valid - not | |
726 | 1..3. | |
727 | (is_iso9660): New function, verify a CD9660 File system. | |
728 | (pk_disklabel_create_instance): Start expanding so that active | |

731 | Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
732 | ||
733 | * The cap object was retaining a reference to the instance of a | |
734 | device after it was deleted. Instead add and remove cap's from the | |
735 | cap db as they are created and deleted. This ensuring that a | |
736 | capibility is only used during the lifetime of the corresponding | |
737 | object. | |
738 | ||
739 | * cap.h, cap.c: Correct cap type - was signed32 should be | |
740 | signed_cell. | |
741 | ||
742 | * cap.c (cap_add, cap_remove): New methods for cap object that | |
743 | allow the explicit addition and removal of internal objects that | |
744 | the cap knows about. | |
745 | ||
746 | * cap.c (cap_init): Rewrite. Verify that the only objects | |
747 | remaining in the cap data base are those that were entered first. | |
748 | Thse objects will be the permenant ones. | |
749 | * device.c (device_init_address): Remember to initialize the cap | |
750 | database. | |
751 | ||
752 | * device.c (device_create_instance_from): Explicitly add device | |
753 | instances to the cap database. Simplify create code. | |
754 | (device_instance_delete): Explicitly remove device instances from | |
755 | the cap database. | |
756 | ||
757 | * device.c (device_create_from): Explicitly add a device to the | |
758 | cap data base. | |
759 | ||
760 | * device.c (device_create_from): Always set the cap members. | |

762 | * hw_disk.c: Output the instance when tracing. | |
763 | ||

765 | ||
766 | * tree.c (split_device_specifier): Add support for aliases when | |
767 | looking up a device. Now needs a device as an argument. | |
768 | (split_property_specifier): Ditto. | |
769 | ||
770 | Sun Jan 19 15:28:23 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
771 | ||
772 | * The memory "claim" and "release" methods take an address and | |
773 | size as arguments. These may be multi cell values. Initially fix | |
774 | the memory code so that they check/detect this. Leave the | |
775 | adjustment of any clients to later. | |
776 | ||
777 | * hw_memory.c (hw_memory_instance_claim, | |
778 | hw_memory_instance_release): Handle multi-cell memory devices. | |

782 | ||
783 | Fri Jan 17 12:01:07 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
784 | ||
785 | * device.h, device.c (device_instance_call_method): Correct return | |
786 | type - can return either 0 or -1, hence should be a signed type. | |

788 | ||
789 | * hw_memory.c (hw_memory_instance_claim, | |
790 | hw_memory_instance_release): Update. | |

1997 | ||
1998 | * std-config.h (SEMANTICS_INLINE): By default, mask out the | |
1999 | inlining of semantic functions from DEFAULT_INLINE. Almost all | |
2000 | configurations call the semantic code via a pointer so there is | |
2001 | little benefit. | |
2002 | ||
2003 | * std-config.h (ICACHE_INLINE): Ditto. | |
2004 | ||
2005 | Thu Jul 25 20:07:30 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |

2032 | ||
2033 | * gen-idecode.c (print_idecode_switch_illegal): Include a break | |
2034 | when generating illegal instructions. This was commented out | |
2035 | which is a hangover from looking a at switch statements generated | |
2036 | using indirect jumps. | |
2037 | ||
2038 | Tue Jul 23 20:57:01 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
2039 | ||
2040 | * igen.c (print_my_defines): Replaces print_define_my_index. | |

2045 | ||
2046 | * gen-support.c (gen_support_h): Add optional include to created | |
2047 | support.h so that, like cpu, it is optionally inlined for all | |
2048 | modules that include it. | |
2049 | * inline.h, inline.c: Adjust so that support.[hc] is handled the | |
2050 | same as cpu.[hc]. | |
2051 | ||
2052 | * idecode_fields.h (LABEL, GOTO): Macro's that create a unique | |
2053 | name for a lable and then branch to it. | |
2054 | ||
2055 | * ppc-instructions (convert_to_integer, Floating Round to | |
2056 | Single-Precision, Floating Convert from Integer Doubleword): Use | |
2057 | LABEL and GOTO instead of the recently added switch statements. | |

2065 | ||
2066 | * configure.in (--enable-sim-line-nr): Typo - sim_line-nr. | |
2067 | * (--enable-sim-inline): Reorder patern matching of arguments so | |
2068 | that SUPPORT=ALL_INLINE is reconized as *=* and not *_INLINE. | |
2069 | ||
2070 | * configure: rebuild. | |
2071 | ||
2072 | Mon Jul 22 23:25:08 1996 Andrew Cagney <cagney@highland.com.au> | |
2073 | ||
2074 | * configure.in (--enable-sim-hardware, --enable-sim-packages): New | |
2075 | configuration options. Let the user specify the packages or | |
2076 | hardware devices that are to be included in the build. Makes it | |
2077 | possible for user packages to be specified. | |
2078 | ||
2079 | * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and | |
2080 | hardware instead of checking it using ls. configure.in should | |
2081 | have taken care of any problems. | |
2082 | (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure. | |
2083 | ||

2085 | ||
2086 | * psim.c (psim_options): Enter the argument to the memory size | |
2087 | option directly into the device tree. Was using atol() which is | |

2091 | ||
2092 | * configure.in (icache): Extend icache flag to include an insn | |
2093 | option. If specifyed the insn - aka instruction - is included in | |
2094 | the instruction cache. Make this the default. | |
2095 | * configure: re-generate. | |
2096 | ||
2097 | * igen.c (main), igen.h: Add option -S - inSn - for specifying | |

2121 | ||
2122 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
2123 | ||
2124 | * gen-idecode.c: Output the complete run_until_stop function | |
2125 | instead of just the code to handle a single instruction issue. | |
2126 | * : Have the generated idecode.c include inline.c (instead of psim.c). | |
2127 | ||
2128 | * std-config.h: Change psim.c so that it isn't inlined (as this is | |
2129 | no longer needed). | |
2130 | ||
2131 | * psim.c (run_until_stop): Delete the old run_until_stop function | |
2132 | instead calling the idecode_run and idecode_run_until_stop | |
2133 | functions that gen-idecode.c is now creating. | |
2134 | ||
2135 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
2136 | ||

2160 | corresponding call to ITRACE so that it still matches. | |
2161 | ||
2162 | * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead | |
2163 | of ITRACE. The CPP line directives would have previously set the | |
2164 | line-nr and file name so ITRACE isn't needed. | |

2169 | idecode generation option. Instead of generating and calling | |
2170 | separate functions containing the semantic and icache code | |
2171 | generate a single monolythic function and use goto's (and GCC's | |
2172 | indirect jump) to move between code blocks. | |
2173 | ||
2174 | * Makefile.in: Add sim_jump flag to those passed to igen. | |
2175 | ||
2176 | * configure.in: New option --enable-sim-jump (default disabled) | |
2177 | ||
2178 | * ppc-instructions: Eliminate any uses of labels and goto's. | |
2179 | These result in duplicate declarations when a single flat function | |
2180 | is being create. | |
2181 | ||
2182 | * ppc-opcode-jump: New file. Set of opcode rules useful when | |
2183 | testing jumping idecodes. | |

2191 | decode functions. | |
2192 | ||
2193 | * configure.in (--enable-sim-icache): Accept an option list such | |
2194 | as 1024,define. Add a new choice to the list - semantic - which | |
2195 | will cause igen to generate instruction decode functions that | |
2196 | include the corresponding semantic code. | |
2197 | ||
2198 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
2199 | ||
2200 | * configure.in: New option --enable-sim-line-nr (default enabled). | |

2206 | ||
2207 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
2208 | ||
2209 | * igen.c (main): Revamp the options so that more letters are | |
2210 | available. | |
2211 | ||

2213 | ||
2214 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
2215 | ||
2216 | * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so | |
2217 | that they use the same technique as igen (ie a dummy targets | |
2218 | tmp-pk and tmp-hw are created). | |
2219 | ||
2220 | Mon Jun 24 22:28:00 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
2221 | ||

3180 | * device.c (external_to_device) : New function that provides a | |
3181 | standard mapping between a devices internal representation (a | |
3182 | pointer) and its external (or what is passed to a client) | |
3183 | representation (a phandle). Implement using the cap object | |
3184 | attached to the root node. | |
