64 | Make the simulator compatible with the MPC750. It would be nicer | |
65 | to make this a real multi-sim, but that's more work than we have | |
66 | time for. | |
67 | * emul_generic.c (emul_add_tree_options): Only require strict | |
68 | alignment if it was explicitly requested at configuration time. | |
69 | Don't make it the default for little-endian machines. | |
70 | * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4, | |
71 | MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1, | |
72 | THRM2, THRM3): Plop in the MPC750 SPR registers. | |
73 | (DABR): This is weird. This was HID5, but the PPC spec says this | |
74 | should be DABR; why did some random processor use it for something | |
75 | else? The HID5 entry dates back to the original checkin of the | |
76 | simulator code in 1995, so remove it. | |
77 | * sim_calls.c (register_names): Delete this; since the user can | |
78 | now change GDB's list of register names dynamically, we can't | |
79 | pretend there's a static mapping here. | |
80 | (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME | |
81 | function to get the register name. That ought to be accurate. | |
82 | However, we're changing a compile-time dependency (using the | |
83 | REGISTER_NAMES macro) into a link- and run-time dependency | |
84 | (calling REGISTER_NAME, which happens to be a function call on the | |
85 | PPC). | |
86 | ||
87 | 1999-01-22 Jim Lemke <jlemke@cygnus.com> | |
88 | ||
89 | * igen.c(gen_semantics_[ch]): setup/use of new option | |
90 | (-o mpc860c0[=n]). | |
91 | interrupts.[ch](mpc860c0_instruction_program_interrupt): added. | |
92 | ppc-instructions(the four branch insn groups): detect problematic br's. | |
93 | psim.c(is_num - added, psim_options): Parse and init new option. | |
94 | These changes are currently under #ifdef WITH_OPTION_MPC860C0. | |

107 | ||
108 | * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function, | |
109 | poll the external environment. | |
110 | ||
111 | 1998-11-19 Michael Meissner <meissner@cygnus.com> | |
112 | ||
113 | * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the | |
114 | fractional type, so that quiet NaN's aren't treated like | |
115 | Infinities. | |
116 | ||
117 | Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com> | |
118 | ||
119 | * table.c (table_open): For cygwin hosts, we need to use the | |
120 | return value from the read routine as the number of bytes to | |
121 | process. This apparently is due to text-mode vs binary-mode. If | |
122 | the mounts are done text-mode, then the size returnedby fstat() | |
123 | may be different than the number of bytes "read" in text mode. | |

148 | Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com> | |
149 | ||
150 | * Makefile.in: The run target depended on a target psim$(EXEEXT), | |
151 | but there was no such target, only plain psim. So I changed the | |
152 | run target to depend on psim. | |
153 | ||
154 | Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com> | |

429 | ||
430 | * Many of the ppc-opcode-* files are identical baring the type of | |
431 | lookup table. Instead of having multiple tables, igen can do this | |
432 | via an additional option. | |
433 | ||
434 | * ld-decode.h, ld-decode.c (force_decode_gen_type): New function, | |

470 | ||
471 | * emul_chirp.c (emul_chirp_create): Handle a virtbase of -1 being | |
472 | found in the device tree. | |
473 | ||
474 | Wed Feb 5 10:56:27 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
475 | ||
476 | * Property create/initialization still wasn't correctly ordered. | |
477 | Should be delaying everything related to ihandle creation until | |
478 | after the rest of the tree has been established. | |
479 | ||
480 | * device.c (device_find_ihandle_runtime_property): Update. | |

497 | works for normal and boolean table entries. | |
498 | ||
499 | * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now | |
500 | valid. Handle this just like *_{read,write}_register now handles | |
501 | it. | |
502 | ||
503 | Mon Feb 3 17:18:16 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |

514 | max iterations exceeded. | |
515 | ||
516 | * gen-idecode.c: Re-work the table lookup code so that it assumes | |
517 | that the entry is a leaf by default. Simplify the boolean table | |
518 | entry code so that it involves a mask + test instead of shift + | |
519 | shift + mask + test. | |
520 | ||
521 | * gen-idecode.c: Correct generated igen body so that it no drops | |
522 | or doubles clock interrupts. | |

552 | ||
553 | * misc.c (name2i): Possibly abort if an invalid name is | |
554 | encountered. | |

556 | ||
557 | Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
558 | ||
559 | * When performance monitoring is disabled, it is still possible to | |
560 | determine the simulation speed by looking at the number of elapsed | |
561 | ticks recorded by the event queue. | |
562 | ||
563 | * psim.c (psim_write_register, psim_read_register): Force the cpu | |
564 | to zero when it is either of `-1' or `nr_cpus'. In both cases the | |
565 | next cpu would be zero any way. | |
566 | ||
567 | * mon.c (mon_print_info): If possible, print the system cycle | |
568 | performance. This is an indication of the number of instructions | |
569 | per second. | |
570 | ||
571 | Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
572 | ||
573 | * The code to allow an event queue to be updated during a signal | |
574 | was missing. For main.c, a cntrl-c simulation termination wasn't | |
575 | handled cleanly. | |
576 | ||
577 | * The simulation would not correctly restart if an event requested | |
578 | that the simulation be halted. | |
579 | ||
580 | * psim.c (psim_options): Add hack to -i option to optionally | |
581 | include a level vis -i2. | |
582 | (psim_usage): Document. | |
583 | ||

585 | cntrl-c occures schedule an event to halt the simulation. | |
586 | (main): Catch CNTRL-C signals with the function cntrl_c. | |
587 | ||
588 | * events.c (event_queue_process): Mask interrupts while | |
589 | manipulating the async event queue. | |
590 | (event_queue_init): Ditto. | |
591 | (event_queue_schedule_after_signal): Ditto. | |
592 | ||
593 | * events.c (event_queue_process): Mark the event queue as being in | |
594 | the processing state when processing has started. Adjust code | |
595 | so that it is tolerant of halts. | |
596 | (event_queue_init): Start the event queue out with processing | |
597 | false. | |
598 | (event_queue_tick): Check that processing isn't still being | |
599 | performed. | |
600 | ||
601 | * gen-idecode.c (print_run_until_stop_body): Call | |
602 | event_queue_process_events to clear possibly pending events before | |
603 | starting a simulation run. Re-arange main loop so that simulator | |
604 | is correctly restarted when an event halts the simulation. | |
605 | ||
606 | * psim.c (psim_halt): Handle an event halting the simulation. | |
607 | * psim.c (psim_init): Adjust initial cpu - == -1 - to match | |

609 | ||
610 | Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
611 | ||
612 | * ppc-opcode-complex: Correct typo - was expanding ORA instead of | |
613 | RA. Based on instruction frequency stats, expand additional | |
614 | instructions. | |
615 | * ppc-instructions: Change all `RA == 0' to RA_is_0. | |
616 | ||
617 | * ppc-opcode-stupid: Move all but the basic table in -complex into | |
618 | here. Update to new format. | |
619 | ||
620 | * Makefile.in (tmp-defines): New target. Force defines.h to always | |
621 | be built. Hence get ppc-opcode-goto to build. | |
622 | ||
623 | Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
624 | ||
625 | * hw_com.c (hw_com_instance_read, hw_com_instance_write): | |
626 | Implement. | |
627 | ||
628 | Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
629 | ||
630 | * hw_trace.c (hw_trace_init_data): Delete. The trace options need | |
631 | to be initialized independant of the rest of the simulation | |
632 | initalization. Otherwize a trace option explictly set from gdb | |
633 | could be overridden by hw_trace. | |
634 | ||
635 | * psim.c (psim_options): Clarify reason why the trace ioctl occures. | |
636 | ||
637 | * FIXME: The trace code is too scattered - hw_trace.c, psim.c, | |
638 | debug.c. It could be much simpler. | |
639 | ||
640 | Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
641 | ||
642 | * Some devices support removable media. Add hooks to the disk | |
643 | device so that it supports this. | |
644 | ||
645 | * device.c (device_add_string_array_property, | |
646 | device_find_string_array_property): New functions, manipulate | |
647 | properties containing an array of strings. | |
648 | (device_find_string_property): Allow a string array. | |
649 | (device_init_static_properties): Update. | |
650 | (device_init_runtime_properties): Update. | |
651 | ||
652 | * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk | |

656 | string array - use the first entry for the initial file image. | |
657 | ||
658 | * tree.c (print_string_aray_property): New function - print a | |
659 | string array. | |
660 | (print_properties): Adjust. | |
661 | (print_string): Write a string, handling double quotes. | |
662 | ||
663 | * device.h: Define an ioctl to `change-media' with an optional new | |
664 | media image. | |
665 | ||
666 | * hw_disk.c: Allow floppy disk devices to be specified. | |
667 | ||
668 | * psim.c (psim_command): New function, parse more complex psim | |
669 | commands such as "change-media" and "trace". | |
670 | * sim_calls.c (sim_do_command): Use. | |
671 | ||
672 | Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
673 | ||
674 | * For expressions like (RA == 0) that are entered in to the cache | |
675 | as RA_is_0. If possible generate the result of the expression so | |
676 | that the compiler gets a better chance of eliminating dead | |
677 | branches. | |
678 | ||
679 | * gen-icache.c (print_icache_extraction): For a cache entry of | |
680 | the form <name>_is_<const> where it is a boolean field, generate | |
681 | the result of the expression instead of the expression its self. | |
682 | (print_icache_body): Remove code that was looking for *_is_0 and | |
683 | then generating corresponding definitions. | |
684 | ||
685 | * gen-icache.c (print_icache_struct): If there is no cache, do not | |
686 | output expressions in idecode.h file. | |
687 | ||
688 | * gen-icache.c (print_icache_body): Output them here. | |
689 | ||
690 | * ppc-opcode-complex: Clarify constant values for SPR==LR register | |

694 | ||
695 | Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
696 | ||
697 | * The code that put values in and extracted values from the cache | |
698 | was too compilicated. The cache table did not allow values to be | |
699 | computed from cache entries. #defines could only be used when a | |
700 | cache was present, remove the restriction. | |
701 | ||
702 | * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A | |
703 | scratch variable is defined when a cache entry is beinf | |
704 | filled. Change the definition of a COMPUTE variable to be defined | |
705 | when the cache entry is being used. | |
706 | * gen-icache.c: Update. | |
707 | ||
708 | * ld-cache.h, ld-cache.c: Change field names so that their meaning | |
709 | is more obvious. old_name->field_name, new_name->derived_name. | |
710 | * gen-icache.c: Update | |
711 | ||
712 | * gen-icache.h, gen-icache.c (print_icache_body): Make the three | |
713 | different types of cache code - put into cache, extract from | |
714 | cache, no cache - an explicit argument to print_icache_body. | |
715 | * gen-icache.c (print_icache_extraction): Ditto. | |
716 | ||
717 | * gen-semantics.c (print_c_semantic): Update use. | |
718 | * gen-idecode.c (print_jump_insn): Update use. | |
719 | * gen-icache.c (print_icache_function): Update use. | |
720 | ||
721 | * igen.c (main): Change 'R' option so that it does not force the | |
722 | cache. | |
723 | ||
724 | * configure.in (enable-sim-icache): Clarify description. Make | |
725 | #define one of the defaults regardless of the cache. Probably | |
726 | should revamp and add a separate option. | |
727 | ||
728 | Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
729 | ||
730 | * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos | |
731 | partition numbering. | |

739 | ||
740 | * The cap object was retaining a reference to the instance of a | |
741 | device after it was deleted. Instead add and remove cap's from the | |
742 | cap db as they are created and deleted. This ensuring that a | |
743 | capibility is only used during the lifetime of the corresponding | |
744 | object. | |
745 | ||
746 | * cap.h, cap.c: Correct cap type - was signed32 should be | |
747 | signed_cell. | |
748 | ||
749 | * cap.c (cap_add, cap_remove): New methods for cap object that | |
750 | allow the explicit addition and removal of internal objects that | |
751 | the cap knows about. | |
752 | ||
753 | * cap.c (cap_init): Rewrite. Verify that the only objects | |
754 | remaining in the cap data base are those that were entered first. | |
755 | Thse objects will be the permenant ones. | |
756 | * device.c (device_init_address): Remember to initialize the cap | |
757 | database. | |
758 | ||

772 | ||
773 | * tree.c (split_device_specifier): Add support for aliases when | |
774 | looking up a device. Now needs a device as an argument. | |
775 | (split_property_specifier): Ditto. | |
776 | ||
777 | Sun Jan 19 15:28:23 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
778 | ||
779 | * The memory "claim" and "release" methods take an address and | |
780 | size as arguments. These may be multi cell values. Initially fix | |
781 | the memory code so that they check/detect this. Leave the | |
782 | adjustment of any clients to later. | |
783 | ||
784 | * hw_memory.c (hw_memory_instance_claim, | |
785 | hw_memory_instance_release): Handle multi-cell memory devices. | |

791 | ||
792 | * device.h, device.c (device_instance_call_method): Correct return | |
793 | type - can return either 0 or -1, hence should be a signed type. | |

795 | ||
796 | * hw_memory.c (hw_memory_instance_claim, | |
797 | hw_memory_instance_release): Update. | |

2004 | ||
2005 | * std-config.h (SEMANTICS_INLINE): By default, mask out the | |
2006 | inlining of semantic functions from DEFAULT_INLINE. Almost all | |
2007 | configurations call the semantic code via a pointer so there is | |
2008 | little benefit. | |
2009 | ||
2010 | * std-config.h (ICACHE_INLINE): Ditto. | |
2011 | ||

2038 | always update the cache_entries semantic and address fields. | |
2039 | ||
2040 | * gen-idecode.c (print_idecode_switch_illegal): Include a break | |
2041 | when generating illegal instructions. This was commented out | |
2042 | which is a hangover from looking a at switch statements generated | |
2043 | using indirect jumps. | |
2044 | ||
2045 | Tue Jul 23 20:57:01 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
2046 | ||
2047 | * igen.c (print_my_defines): Replaces print_define_my_index. | |

2050 | * gen-idecode.c (print_jump_insn): Adjust. | |
2051 | * gen-semantics.c (print_c_semantic): Adjust. | |
2052 | ||
2053 | * gen-support.c (gen_support_h): Add optional include to created | |
2054 | support.h so that, like cpu, it is optionally inlined for all | |
2055 | modules that include it. | |
2056 | * inline.h, inline.c: Adjust so that support.[hc] is handled the | |
2057 | same as cpu.[hc]. | |
2058 | ||
2059 | * idecode_fields.h (LABEL, GOTO): Macro's that create a unique | |
2060 | name for a lable and then branch to it. | |
2061 | ||
2062 | * ppc-instructions (convert_to_integer, Floating Round to | |
2063 | Single-Precision, Floating Convert from Integer Doubleword): Use | |
2064 | LABEL and GOTO instead of the recently added switch statements. | |

2072 | ||
2073 | * configure.in (--enable-sim-line-nr): Typo - sim_line-nr. | |
2074 | * (--enable-sim-inline): Reorder patern matching of arguments so | |
2075 | that SUPPORT=ALL_INLINE is reconized as *=* and not *_INLINE. | |
2076 | ||
2077 | * configure: rebuild. | |
2078 | ||
2079 | Mon Jul 22 23:25:08 1996 Andrew Cagney <cagney@highland.com.au> | |
2080 | ||
2081 | * configure.in (--enable-sim-hardware, --enable-sim-packages): New | |
2082 | configuration options. Let the user specify the packages or | |
2083 | hardware devices that are to be included in the build. Makes it | |
2084 | possible for user packages to be specified. | |
2085 | ||
2086 | * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and | |
2087 | hardware instead of checking it using ls. configure.in should | |
2088 | have taken care of any problems. | |
2089 | (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure. | |
2090 | ||

2098 | ||
2099 | * configure.in (icache): Extend icache flag to include an insn | |
2100 | option. If specifyed the insn - aka instruction - is included in | |
2101 | the instruction cache. Make this the default. | |
2102 | * configure: re-generate. | |
2103 | ||
2104 | * igen.c (main), igen.h: Add option -S - inSn - for specifying | |

2128 | ||
2129 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
2130 | ||
2131 | * gen-idecode.c: Output the complete run_until_stop function | |
2132 | instead of just the code to handle a single instruction issue. | |
2133 | * : Have the generated idecode.c include inline.c (instead of psim.c). | |
2134 | ||
2135 | * std-config.h: Change psim.c so that it isn't inlined (as this is | |
2136 | no longer needed). | |
2137 | ||
2138 | * psim.c (run_until_stop): Delete the old run_until_stop function | |
2139 | instead calling the idecode_run and idecode_run_until_stop | |
2140 | functions that gen-idecode.c is now creating. | |
2141 | ||
2142 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
2143 | ||

2167 | corresponding call to ITRACE so that it still matches. | |
2168 | ||
2169 | * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead | |
2170 | of ITRACE. The CPP line directives would have previously set the | |
2171 | line-nr and file name so ITRACE isn't needed. | |

2176 | idecode generation option. Instead of generating and calling | |
2177 | separate functions containing the semantic and icache code | |
2178 | generate a single monolythic function and use goto's (and GCC's | |
2179 | indirect jump) to move between code blocks. | |
2180 | ||
2181 | * Makefile.in: Add sim_jump flag to those passed to igen. | |
2182 | ||
2183 | * configure.in: New option --enable-sim-jump (default disabled) | |
2184 | ||
2185 | * ppc-instructions: Eliminate any uses of labels and goto's. | |
2186 | These result in duplicate declarations when a single flat function | |
2187 | is being create. | |
2188 | ||
2189 | * ppc-opcode-jump: New file. Set of opcode rules useful when | |
2190 | testing jumping idecodes. | |

2198 | decode functions. | |
2199 | ||
2200 | * configure.in (--enable-sim-icache): Accept an option list such | |
2201 | as 1024,define. Add a new choice to the list - semantic - which | |
2202 | will cause igen to generate instruction decode functions that | |
2203 | include the corresponding semantic code. | |
2204 | ||
2205 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |

2213 | ||
2214 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
2215 | ||
2216 | * igen.c (main): Revamp the options so that more letters are | |
2217 | available. | |
2218 | ||

2220 | ||
2221 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
2222 | ||
2223 | * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so | |
2224 | that they use the same technique as igen (ie a dummy targets | |
2225 | tmp-pk and tmp-hw are created). | |
2226 | ||
2227 | Mon Jun 24 22:28:00 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
2228 | ||

3162 | controllers and interrupt controllers can further propogate | |
3163 | interrupt events. | |

3187 | * device.c (external_to_device) : New function that provides a | |
3188 | standard mapping between a devices internal representation (a | |
3189 | pointer) and its external (or what is passed to a client) | |
3190 | representation (a phandle). Implement using the cap object | |
3191 | attached to the root node. | |

3197 | ||
3198 | * Makefile (device.o): Add dependency on cap. | |
3199 | ||
3200 | * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code | |
3201 | needing to translate between internal and external representations | |
3202 | changed to use the external_to_device et.al. device operations. | |
3203 | * emul_chirp.c (chirp_emul_*) : Ditto | |

3214 | * emul_generic.c (emul_write_buffer): Use vm faulting byte | |
3215 | read/write calls for buffer transfers. This will cause a fault to | |
3216 | occure if the transfer fails. CHRP catches the fault while the | |
3217 | others suffer the consequences. | |
