| 159 | ||
| 160 | Make the simulator compatible with the MPC750. It would be nicer | |
| 161 | to make this a real multi-sim, but that's more work than we have | |
| 162 | time for. | |
| 163 | * emul_generic.c (emul_add_tree_options): Only require strict | |
| 164 | alignment if it was explicitly requested at configuration time. | |
| 165 | Don't make it the default for little-endian machines. | |
| 166 | * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4, | |
| 167 | MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1, | |
| 168 | THRM2, THRM3): Plop in the MPC750 SPR registers. | |
| 169 | (DABR): This is weird. This was HID5, but the PPC spec says this | |
| 170 | should be DABR; why did some random processor use it for something | |
| 171 | else? The HID5 entry dates back to the original checkin of the | |
| 172 | simulator code in 1995, so remove it. | |
| 173 | * sim_calls.c (register_names): Delete this; since the user can | |
| 174 | now change GDB's list of register names dynamically, we can't | |
| 175 | pretend there's a static mapping here. | |
| 176 | (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME | |
| 177 | function to get the register name. That ought to be accurate. | |
| 178 | However, we're changing a compile-time dependency (using the | |
| 179 | REGISTER_NAMES macro) into a link- and run-time dependency | |
| 180 | (calling REGISTER_NAME, which happens to be a function call on the | |
| 181 | PPC). | |
| 182 | ||
| 183 | 1999-01-22 Jim Lemke <jlemke@cygnus.com> | |
| 184 | ||
| 185 | * igen.c(gen_semantics_[ch]): setup/use of new option | |
| 186 | (-o mpc860c0[=n]). | |
| 187 | interrupts.[ch](mpc860c0_instruction_program_interrupt): added. | |
| 188 | ppc-instructions(the four branch insn groups): detect problematic br's. | |
| 189 | psim.c(is_num - added, psim_options): Parse and init new option. | |
| 190 | These changes are currently under #ifdef WITH_OPTION_MPC860C0. | |
| 191 | ||
| 192 | 1998-12-01 Ken Raeburn <raeburn@cygnus.com> | |
| 193 | ||
| 194 | * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99. | |
| 195 | ||
| 196 | Fri Nov 20 12:17:28 1998 Andrew Cagney <cagney@b1.cygnus.com> | |
| 197 | ||
| 198 | * main.c (sim_io_poll_quit): Stub function. | |
| 199 | ||
| 200 | * events.c (SIM_EVENTS_POLL_RATE): Define. | |
| 201 | (sim_events_poll): Copy function from common/sim-events.c. | |
| 202 | (event_queue_init): Copy scheduling of sim_events_poll from same. | |
| 203 | ||
| 204 | * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function, | |
| 205 | poll the external environment. | |
| 206 | ||
| 207 | 1998-11-19 Michael Meissner <meissner@cygnus.com> | |
| 208 | ||
| 209 | * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the | |
| 210 | fractional type, so that quiet NaN's aren't treated like | |
| 211 | Infinities. | |
| 212 | ||
| 213 | Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com> | |
| 214 | ||
| 215 | * table.c (table_open): For cygwin hosts, we need to use the | |
| 216 | return value from the read routine as the number of bytes to | |
| 217 | process. This apparently is due to text-mode vs binary-mode. If | |
| 218 | the mounts are done text-mode, then the size returnedby fstat() | |
| 219 | may be different than the number of bytes "read" in text mode. | |
| 220 | ||
| 221 | Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com> | |
| 222 | ||
| 223 | * emul_netbsd.c (do_open): fix order-of-evaluation problem. | |
| 224 | (do_close): ditto. | |
| 225 | (do_fstat): ditto. | |
| 226 | (do_lstat): ditto. | |
| 227 | ||

| 231 | ||
| 232 | Mon Jun 29 10:57:36 1998 Michael Snyder <msnyder@cleaver.cygnus.com> | |
| 233 | ||
| 234 | * sim_calls.c (sim_fetch_register, sim_store_register): | |
| 235 | return zero when nothing to do. | |
| 236 | ||
| 237 | 1998-06-26 Michael Meissner <meissner@cygnus.com> | |
| 238 | ||
| 239 | * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h. | |
| 240 | * configure: Regenerate. | |
| 241 | * emul_{netbsd,unix}.c (toplevel): No longer try to include | |
| 242 | sys/mount.h. It conflicts on Linux when gnu libc2 is used. | |
| 243 | ||
| 244 | Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com> | |
| 245 | ||
| 246 | * Makefile.in: The run target depended on a target psim$(EXEEXT), | |
| 247 | but there was no such target, only plain psim. So I changed the | |
| 248 | run target to depend on psim. | |
| 249 | ||
| 250 | Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com> | |
| 251 | ||
| 252 | * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are | |
| 253 | now defined in ../common/aclocal.m4, and the double definition causes | |
| 254 | problems with AC_SUBST of EXEEXT. | |
| 255 | * configure: Regenerate. | |
| 256 | ||
| 257 | Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com> | |

| 525 | ||
| 526 | * Many of the ppc-opcode-* files are identical baring the type of | |

| 571 | ||
| 572 | * Property create/initialization still wasn't correctly ordered. | |
| 573 | Should be delaying everything related to ihandle creation until | |
| 574 | after the rest of the tree has been established. | |
| 575 | ||
| 576 | * device.c (device_find_ihandle_runtime_property): Update. | |
| 577 | (device_add_ihandle_runtime_property): Update. | |

| 594 | ||
| 595 | * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now | |

| 610 | max iterations exceeded. | |
| 611 | ||
| 612 | * gen-idecode.c: Re-work the table lookup code so that it assumes | |
| 613 | that the entry is a leaf by default. Simplify the boolean table | |
| 614 | entry code so that it involves a mask + test instead of shift + | |
| 615 | shift + mask + test. | |
| 616 | ||
| 617 | * gen-idecode.c: Correct generated igen body so that it no drops | |
| 618 | or doubles clock interrupts. | |

| 629 | Wed Jan 29 12:32:41 1997 Michael Meissner <meissner@tiktok.cygnus.com> | |
| 630 | ||
| 631 | * configure.in (sim_callback): If the gdb is post 4.16, configure | |

| 649 | * misc.c (name2i): Possibly abort if an invalid name is | |
| 650 | encountered. | |
| 651 | * ld-decode.c: Abort if the table type isn't found. | |
| 652 | ||
| 653 | Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
| 654 | ||
| 655 | * When performance monitoring is disabled, it is still possible to | |
| 656 | determine the simulation speed by looking at the number of elapsed | |
| 657 | ticks recorded by the event queue. | |
| 658 | ||
| 659 | * psim.c (psim_write_register, psim_read_register): Force the cpu | |
| 660 | to zero when it is either of `-1' or `nr_cpus'. In both cases the | |
| 661 | next cpu would be zero any way. | |
| 662 | ||
| 663 | * mon.c (mon_print_info): If possible, print the system cycle | |
| 664 | performance. This is an indication of the number of instructions | |
| 665 | per second. | |
| 666 | ||
| 667 | Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
| 668 | ||
| 669 | * The code to allow an event queue to be updated during a signal | |
| 670 | was missing. For main.c, a cntrl-c simulation termination wasn't | |
| 671 | handled cleanly. | |
| 672 | ||
| 673 | * The simulation would not correctly restart if an event requested | |
| 674 | that the simulation be halted. | |
| 675 | ||
| 676 | * psim.c (psim_options): Add hack to -i option to optionally | |
| 677 | include a level vis -i2. | |
| 678 | (psim_usage): Document. | |
| 679 | ||
| 680 | * main.c (cntrl_c, cntrl_c_simulation): New functions. When a | |
| 681 | cntrl-c occures schedule an event to halt the simulation. | |
| 682 | (main): Catch CNTRL-C signals with the function cntrl_c. | |
| 683 | ||
| 684 | * events.c (event_queue_process): Mask interrupts while | |
| 685 | manipulating the async event queue. | |
| 686 | (event_queue_init): Ditto. | |
| 687 | (event_queue_schedule_after_signal): Ditto. | |
| 688 | ||
| 689 | * events.c (event_queue_process): Mark the event queue as being in | |
| 690 | the processing state when processing has started. Adjust code | |
| 691 | so that it is tolerant of halts. | |
| 692 | (event_queue_init): Start the event queue out with processing | |
| 693 | false. | |
| 694 | (event_queue_tick): Check that processing isn't still being | |

| 698 | event_queue_process_events to clear possibly pending events before | |
| 699 | starting a simulation run. Re-arange main loop so that simulator | |
| 700 | is correctly restarted when an event halts the simulation. | |
| 701 | ||
| 702 | * psim.c (psim_halt): Handle an event halting the simulation. | |
| 703 | * psim.c (psim_init): Adjust initial cpu - == -1 - to match | |
| 704 | reworked idecode. | |
| 705 | ||
| 706 | Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
| 707 | ||
| 708 | * ppc-opcode-complex: Correct typo - was expanding ORA instead of | |
| 709 | RA. Based on instruction frequency stats, expand additional | |
| 710 | instructions. | |
| 711 | * ppc-instructions: Change all `RA == 0' to RA_is_0. | |
| 712 | ||
| 713 | * ppc-opcode-stupid: Move all but the basic table in -complex into | |
| 714 | here. Update to new format. | |
| 715 | ||
| 716 | * Makefile.in (tmp-defines): New target. Force defines.h to always | |
| 717 | be built. Hence get ppc-opcode-goto to build. | |
| 718 | ||
| 719 | Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
| 720 | ||
| 721 | * hw_com.c (hw_com_instance_read, hw_com_instance_write): | |

| 723 | ||
| 724 | Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
| 725 | ||
| 726 | * hw_trace.c (hw_trace_init_data): Delete. The trace options need | |
| 727 | to be initialized independant of the rest of the simulation | |
| 728 | initalization. Otherwize a trace option explictly set from gdb | |
| 729 | could be overridden by hw_trace. | |
| 730 | ||
| 731 | * psim.c (psim_options): Clarify reason why the trace ioctl occures. | |
| 732 | ||
| 733 | * FIXME: The trace code is too scattered - hw_trace.c, psim.c, | |
| 734 | debug.c. It could be much simpler. | |
| 735 | ||
| 736 | Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
| 737 | ||
| 738 | * Some devices support removable media. Add hooks to the disk | |
| 739 | device so that it supports this. | |
| 740 | ||
| 741 | * device.c (device_add_string_array_property, | |
| 742 | device_find_string_array_property): New functions, manipulate | |
| 743 | properties containing an array of strings. | |
| 744 | (device_find_string_property): Allow a string array. | |
| 745 | (device_init_static_properties): Update. | |
| 746 | (device_init_runtime_properties): Update. | |
| 747 | ||
| 748 | * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk | |
| 749 | media. If no file image is specified, use the next one in the | |
| 750 | image property list. | |

| 836 | * The cap object was retaining a reference to the instance of a | |
| 837 | device after it was deleted. Instead add and remove cap's from the | |
| 838 | cap db as they are created and deleted. This ensuring that a | |

| 2297 | as 1024,define. Add a new choice to the list - semantic - which | |
| 2298 | will cause igen to generate instruction decode functions that | |
| 2299 | include the corresponding semantic code. | |
