Used to tweak 1485 the frequency at which the poll_quit callback is called. 1486 (poll_quit_count): New global. 1487 (sim_io_poll_quit): Only call the poll_quit callback 1488 after the specified POLL_QUIT_INTERVAL. 1489 1490 1999-02-22 Jim Lemke <jlemke (a] cygnus.com> 1491 1492 * dc-complex: Force expansion on all bits of field BO. 1493 Previously, the least-significant (prediction) bit was ignored. 1494 * ppc-instructions (conditional branches): Implement mpc860c0 option. 1495 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option. 1496 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option. 1497 * interrupts.h: Added "mpc860c0_instruction_program_interrupt". 1498 * interrupts.c (program_interrupt): Added handling for above interrupt. 1499 1500 1999-02-01 Jim Blandy <jimb (a] zwingli.cygnus.com> 1501 1502 Make the simulator compatible with the MPC750. It would be nicer 1503 to make this a real multi-sim, but that's more work than we have 1504 time for. 1505 * emul_generic.c (emul_add_tree_options): Only require strict 1506 alignment if it was explicitly requested at configuration time. 1507 Don't make it the default for little-endian machines. 1508 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4, 1509 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1, 1510 THRM2, THRM3): Plop in the MPC750 SPR registers. 1511 (DABR): This is weird. This was HID5, but the PPC spec says this 1512 should be DABR; why did some random processor use it for something 1513 else? The HID5 entry dates back to the original checkin of the 1514 simulator code in 1995, so remove it. 1515 * sim_calls.c (register_names): Delete this; since the user can 1516 now change GDB's list of register names dynamically, we can't 1517 pretend there's a static mapping here. 1518 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME 1519 function to get the register name. That ought to be accurate. 1520 However, we're changing a compile-time dependency (using the 1521 REGISTER_NAMES macro) into a link- and run-time dependency 1522 (calling REGISTER_NAME, which happens to be a function call on the 1523 PPC). 1524 1525 1999-01-22 Jim Lemke <jlemke (a] cygnus.com> 1526 1527 * igen.c(gen_semantics_[ch]): setup/use of new option 1528 (-o mpc860c0[=n]). 1529 interrupts.[ch](mpc860c0_instruction_program_interrupt): added. 1530 ppc-instructions(the four branch insn groups): detect problematic br's. 1531 psim.c(is_num - added, psim_options): Parse and init new option. 1532 These changes are currently under #ifdef WITH_OPTION_MPC860C0. 1533 1534 1998-12-01 Ken Raeburn <raeburn (a] cygnus.com> 1535 1536 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99. 1537 1538 Fri Nov 20 12:17:28 1998 Andrew Cagney <cagney (a] b1.cygnus.com> 1539 1540 * main.c (sim_io_poll_quit): Stub function. 1541 1542 * events.c (SIM_EVENTS_POLL_RATE): Define. 1543 (sim_events_poll): Copy function from common/sim-events.c. 1544 (event_queue_init): Copy scheduling of sim_events_poll from same. 1545 1546 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function, 1547 poll the external environment. 1548 1549 1998-11-19 Michael Meissner <meissner (a] cygnus.com> 1550 1551 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the 1552 fractional type, so that quiet NaN's aren't treated like 1553 Infinities. 1554 1555 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley (a] cygnus.com> 1556 1557 * table.c (table_open): For cygwin hosts, we need to use the 1558 return value from the read routine as the number of bytes to 1559 process. This apparently is due to text-mode vs binary-mode. If 1560 the mounts are done text-mode, then the size returnedby fstat() 1561 may be different than the number of bytes "read" in text mode. 1562 1563 Sun Oct 4 00:50:47 1998 Felix Lee <flee (a] cygnus.com> 1564 1565 * emul_netbsd.c (do_open): fix order-of-evaluation problem. 1566 (do_close): ditto. 1567 (do_fstat): ditto. 1568 (do_lstat): ditto. 1569 1570 1998-09-03 Michael Meissner <meissner (a] cygnus.com> 1571 1572 * emul_{netbsd,unix}.c: Update copyright year. 1573 1574 Mon Jun 29 10:57:36 1998 Michael Snyder <msnyder (a] cleaver.cygnus.com> 1575 1576 * sim_calls.c (sim_fetch_register, sim_store_register): 1577 return zero when nothing to do. 1578 1579 1998-06-26 Michael Meissner <meissner (a] cygnus.com> 1580 1581 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h. 1582 * configure: Regenerate. 1583 * emul_{netbsd,unix}.c (toplevel): No longer try to include 1584 sys/mount.h.

The trace options need 2069 to be initialized independant of the rest of the simulation 2070 initalization. Otherwize a trace option explictly set from gdb 2071 could be overridden by hw_trace. 2072 2073 * psim.c (psim_options): Clarify reason why the trace ioctl occures. 2074 2075 * FIXME: The trace code is too scattered - hw_trace.c, psim.c, 2076 debug.c.

Make it all 5474 inline friendly. Instead of having general code emitted by igen, 5475 go the route of having each semantic routine call the appropriate 5476 module. 5477 5478 Thu Nov 16 09:52:26 1995 Michael Meissner <meissner (a] tiktok.cygnus.com> 5479 5480 * table.c (table_entry_read): Allow the annex to have blank lines. 5481 5482 * ppc-instructions: Change lines in model stuff that just have a 5483 tab to just newline.

Add code to 5525 code successful/unsuccessful branch predictions, and the number of 5526 conditional branches that fell through. 5527 5528 Wed Nov 15 17:32:13 1995 Michael Meissner <meissner (a] tiktok.cygnus.com> 5529 5530 * cpu.h (cpu_model): Add declaration. 5531 5532 * cpu.c (struct _cpu): Add model_ptr to hold model specific 5533 information. 5534 (cpu_model): Return the model internal pointer. 5535 (cpu_{create,init,halt}): Call the appropriate model function. 5536 5537 * inline.c (mon.c): Move include of mon.c after model.c. 5538 5539 * mon.c (_cpu_mon): Add fields to count unaligned memory 5540 references. 5541 (mon_issue): Call model_issue, not function_unit_issue. 5542 (mon_{read,write}): Count # of unaligned memory accesses. 5543 (mon_print_info): Switch to calling model_mon_info and 5544 model_mon_info_free instead of function_unit version. Print out 5545 number of unaligned reads/writes. 5546 5547 * {ppc-instructions,igen.c}: More global changes to add model 5548 specific features. 5549 5550 * inline.{c,h}: Provide for inlining options.c. 5551 * options.{c,h}: Ditto. 5552 * std-config.h: Add OPTIONS_INLINE. 5553 5554 Tue Nov 14 04:47:25 1995 Michael Meissner <meissner (a] tiktok.cygnus.com> 5555 5556 * Makefile.in (devices.o, main.o): Update dependency. 5557 5558 * igen.c (gen_model_h): Use correct variable in loop. 5559 (gen_model_c): Use strcmp, strcasecmp. 5560 (gen_model_c): Use EXTERN_MODEL for arrays. 5561 (gen_model_h): Use STATIC_MODEL for arrays. 5562 (lf_print_c_semantic_function_header): Delete unused function. 5563 5564 * main.c (cpu.h): Include cpu.h to get model.h. 5565 5566 * inline.h ({EXTERN,STATIC}_MODEL): Define. 5567 5568 Mon Nov 13 09:14:13 1995 Michael Meissner <meissner (a] tiktok.cygnus.com> 5569 5570 * igen.c ({insn,model}_table_fields): Spell mnemonic correctly. 5571 (gen_itable_h,itable_c_insn): Ditto. 5572 (model support): Move model support around, add support for 5573 model-data, model-internal. Use annex field for model-macros 5574 now. 5575 5576 * configure.in (--enable-sim-inline): If --enable-sim-inline=no, 5577 also define INLINE as nothing. 5578 * configure: Regenerate. 5579 5580 * std-config.h (INLINE): Rather than nuking INLINE, only define it 5581 as __inline__ if any of the INLINE flags are non-zero. 5582 5583 * options.c (print_options): Print out WITH_XOR_ENDAIN. 5584 5585 Mon Nov 13 23:03:45 1995 Andrew Cagney <cagneyhighland.com.au> 5586 5587 * ppc-instructions (rfi): Add missing code. 5588 5589 * cpu.c (cpu_get_time_base): Fix calculation of current value of 5590 time base register. 5591 5592 * ppc-spr-table (TBL, TBU): Fix TBL/TBU entries - was confusing 5593 m[tf]tb with m[tf]spr. 5594 5595 * ppc-instructions (mtspr, mfspr): Fix mttbl - wasn't storing 5596 lower word. 5597 5598 Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au> 5599 5600 * std-config.h (INLINE, STATIC_INLINE): Was being set to static 5601 inline.. Only problem being that with ppc-opcode-simple this gave 5602 it the chance to inline all the idecode functions with potentially 5603 disasterous results on a 16mb PC. For moment hobble INLINE. 5604 5605 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by 5606 default ... 5607 5608 * configure.in: Tweek flags passed to gcc for --with-sim-warnings. 5609 Firstly make them errors and secondly remove the options gcc-245 5610 doesn't reconize. 5611 5612 Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney (a] highland.com.au> 5613 5614 * misc.c (zalloc), cpu.c (cpu_init), devices 5615 (console_io_read_buffer_callback, icu_io_read_buffer_callback, 5616 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset), 5617 sim_calls.c (zalloc) : replace bzero() with memset(). 5618 5619 * emul_netbsd.c (write_direntries), psim.c (psim_read_register, 5620 psim_write_register): replace bcopy() with memcpy(). 5621 5622 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au> 5623 5624 * configure.in: for --disable-sim-inline (--enable-sim-inline=no), 5625 force DEFAULT_INLINE to 0 rather then trusting the std 5626 configuration. 5627 5628 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au> 5629 5630 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix 5631 generation of switch entries in tables - treat the same as 5632 cracking/semantic functions. 5633 5634 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation 5635 of a boolean switch statement (field zero or non-zero). 5636 5637 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the 5638 switch/table generation ability of igen. 5639 5640 * igen.c (idecode_switch_leaf): Fix code output when a switch 5641 statement needs to look up a table. 5642 5643 * igen.c (idecode_declare_if_switch): New function called from 5644 gen_idecode_c - need to declare any idecode switch functions 5645 before they are used in idecode tables. 5646 5647 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf, 5648 idecode_crack_insn): Add is_inline_function argument to code 5649 printing cracker functions which indicates if STATIC_IDECODE or 5650 STATIC_INLINE_IDECODE should be used for definition. For 5651 idecode_crack_insn (which implies not duplicating/expanding) don't 5652 declare function as inline - we assume that the only time this is 5653 code is generated is when things are being tested. For 5654 idecode_crack_leaf, make static (instead of INLINE) if the 5655 instructions parent is a table as function will always be called 5656 via a table. 5657 5658 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not 5659 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be 5660 called directly, all others are called via a table. 5661 5662 * igen.c (lf_print_semantic_function_header, semantics_h_leaf, 5663 semantics_h_insn, semantics_h_function, 5664 lf_print_c_semantic_function, semantics_c_function): Add 5665 is_inline_function argument to lf_print_semantic_function_header 5666 to indicate if an inline or static function declaration/definition 5667 should be output. Depending on situtation call accordingly: 5668 functions (not instruction semantic routines) are always inline; 5669 Semantic routines are made inline when there is no icache (cache 5670 will contain the function address) and are duplicating (see above) 5671 and the parent of the instruction is a switch statement. 5672 5673 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC 5674 and moved to insn_table_find_opcode_field. 5675 5676 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields). 5677 5678 * igen.c (model_c_insn): Suggestion - document the name of the 5679 instruction on each line of the instruction model table. 5680 5681 Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au> 5682 5683 * emul_netbsd.c (do_ioctl): Cleanup compilation. 5684 5685 * sim_callbacks.h (__attribute__): Only define if not defined (was 5686 already defined on NetBSD host). 5687 5688 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au> 5689 5690 * std-config.h (WITH_XOR_ENDIAN), configure.in, Makefile.in: New 5691 macro, indicates if the PowerPC's horrible XOR endian mode should 5692 be suported. Add to configure and make. 5693 5694 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c 5695 (vm_instruction_map_read): If XOR endian, xor the address 5696 with a value from an xor table (indexed by size of access). 5697 5698 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context): 5699 set up xor table to xor if there is a conflict between the 5700 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move 5701 check of suported change of endian mode from cpu.c to vm.c. 5702 5703 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer): 5704 Hopefully added correct hack to handle XOR endian mode. 5705 5706 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates 5707 little endian mode, the model accepts miss aligned transfers. 5708 5709 FIXME: Need to create an `init' device that, during 5710 initializatioin for XOR mode, it mushes (XOR address) all the dma 5711 data before passing it on to the core for storage. Just like the 5712 real thing really. 5713 5714 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au> 5715 5716 * devices.c (halt_io_write_buffer_callback): Use value written to 5717 halt device to determine exit status. Thus allowing 5718 success/failure of OEA tests. 5719 5720 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au> 5721 5722 * ppc-instructions (icbi): If icache present flush it. 5723 5724 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au> 5725 5726 * devices.c (htab_init_callback): Add code to create htab/pte. 5727 5728 * devices.c (dma_file, file_init_callback, htab_init_callback): 5729 New function - Dma the named file into memory at the specified 5730 address. Use. 5731 5732 * device_tree.h, device_tree.c (scand_*): New functions. 5733 5734 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au> 5735 5736 * filter_filename.c, Makefile.in: Change so that only dependant on 5737 a very limited nr of files. Stops an unnecessary dependency. 5738 5739 Tue Nov 7 15:44:33 1995 Andrew Cagney <cagney (a] highland.com.au> 5740 5741 * core.c (core_map_find_mapping): Use cpu_halt rather than error 5742 to abort an access to an undefined address. 5743 5744 Sun Nov 12 07:58:09 1995 Michael Meissner <meissner (a] tiktok.cygnus.com> 5745 5746 * igen.c (model_table_insert_{macro,function}): New functions. 5747 (insn_table_load_insns): Call them. 5748 (gen_model_h): Move section emiting model-macros to be first. 5749 (model_{c,h}_function): New functions cloned from semantic 5750 functions to print out the prototype and function for 5751 model-functions. 5752 (gen_model_{c,h}): Print out model-functions. 5753 5754 * ppc-instructions (model_{start,halt,print_info}): Add dummy 5755 model-functions. 5756 5757 * options.c (print_options): Print out WITH_{,DEFAULT_}MODEL, not 5758 WITH_PPC_{,DEFAULT_}_MODEL. 5759 (options_ppc): Delete now unused function. 5760 (cpu.h): Include cpu.h, not just basics.h. 5761 5762 * std-config.h (WITH_{,DEFAULT_}MODEL): Define. 5763 5764 * igen.c (model_macros, last_model_macro): New statics to keep 5765 track of macros to go in model.h. 5766 (insn_table_load_insns): Add model-macros to model_macros linked 5767 list. 5768 (model_table_fields): Add field for printable name. 5769 (gen_model_h): If there are model macros defined, print them out. 5770 Print out DEFAULT_MODEL as the first model if there any models 5771 specified, otherwise MODEL_NONE. Print out external decl for 5772 current_model. Print out decl for model_set. 5773 (gen_model_c): Add function model_set. Switch to use printable 5774 name for the model, not the internal identifier used. 5775 5776 * psim.c (current_model): New global variable. 5777 5778 * ppc-instructions: Add macros for flag defines. Switch first 5779 model so 604 is first. 5780 5781 * main.c (main): Call model_set, not function_unit_model. 5782 * sim_calls.c (sim_open): Ditto. 5783 * sim_calls.c, Makefile.in: sim_calls.c now

Appears 2.6.3 is confused by just a 6298 macro. 6299 6300 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney (a] highland.com.au> 6301 6302 * ppc-endian.c (SWAP_8): Fix 8 byte swap! 6303 6304 * psim.c (psim_create): Not correctly checking that runtime 6305 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT 6306 matched the compiled in ones. 6307 6308 * debug.h (ITRACE), igen.c: Tidy up more tracing flags - 6309 trace_semantics is now different to trace_idecode, the former 6310 checks the cache. 6311 6312 Tue Oct 24 21:54:13 1995 Andrew Cagney <cagney (a] highland.com.au> 6313 6314 * ppc-instructions (mtsrin): Missing instruction 6315 * ppc-instructions (mfsrin): Missing instruction 6316 * ppc-instructions (eieio): Missing instruction 6317 6318 Tue Oct 24 20:55:29 1995 Andrew Cagney <cagney (a] highland.com.au> 6319 6320 * build-psim: New shell script - see internals for usage, 6321 simplifies the process of building custom simulators. 6322 6323 Mon Oct 23 23:48:59 1995 Andrew Cagney <cagney (a] highland.com.au> 6324 6325 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the 6326 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2. 6327 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE 6328 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on 6329 the instruction or data critical paths. 6330 6331 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from 6332 the inclusion of device_tree.c/emul_generic.c. 6333 6334 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney (a] highland.com.au> 6335 6336 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace 6337 system.[hc]. Start of suport for multiple emulations and 6338 emulation state (os_emul object). 6339 6340 * emul_generic.[hc]: Start of code to implement proper system call 6341 tracing (from spy). 6342 6343 Sun Oct 22 21:33:51 1995 Andrew Cagney <cagney (a] highland.com.au> 6344 6345 * cpu.h, cpu.c (cpu_init): New function, zero the registers before 6346 the processor is started. Fixes problem of registers being 6347 undefined when restarting from within gdb. 6348 6349 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the 6350 instruction cache (if present). Fixes problem of cpu caching gdb 6351 breakpoint instructions. 6352 6353 FIXME: PSIM sometimes aborts calling error(), it should instead 6354 call sim_error() say which takes care of housekeeping such as 6355 saving the CIA before calling error. 6356 6357 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is 6358 used when restarting a simulation because the latter has the 6359 unwanted side effect (well I as a kernel hacker think it is) of 6360 performing an isync when the instruction stream doesn't contain 6361 one. 6362 6363 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney (a] highland.com.au> 6364 6365 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance 6366 monitoring module. Counts both instructions issued and 6367 load/stores. 6368 6369 * NOTE: mon does not contain to count instruction loads as this 6370 information is already available from the mon_issue() hook. 6371 6372 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code. 6373 6374 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach 6375 a common monitor to each of the cpus. Delete 6376 cpu_increment_number_of_insns() and cpu_get_number_of_insns() 6377 replaced by copied code in mon.[hc]. 6378 6379 Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney (a] highland.com.au> 6380 6381 * sim_calls.c, main.c, psim.c (psim_create): always create 6382 `WITH_SMP' cpus. The actual number of CPU's active in a 6383 simulation run is taken from the device node: /init/smp (an 6384 integer). WITH_SMP changed to 2 (remember to put it back to 0). 6385 6386 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney (a] highland.com.au> 6387 6388 * system.c: More system call emulation. If code appears NetBSD 6389 specific, make conditional to being compiled on a NetBSD system 6390 (sigh). 6391 6392 Wed Oct 18 23:02:20 1995 Andrew Cagney <cagney (a] highland.com.au> 6393 6394 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new), 6395 lf.[ch](new), table.[ch](new): Split into two generators - igen 6396 that outputs the instruction tables and dgen that outputs the spr 6397 tables. Add -f (filter out) flag to igen to filter out certain 6398 instructions (ex 64 bit ones) from the created tables. Include 6399 $(LIBIBERTY_LIB) in link options in case host lacks some libc 6400 functions. 6401 6402 * NOTE: igen, since it was originally written for the 6403 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}. 6404 6405 * Makefile.in, std-config.h, ppc-cache-rules(new), 6406 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create 6407 cache-rule and opcode-rule tables from macros found std-config.h. 6408 Delete corresponding macro's from std-config.h. 6409 6410 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output 6411 an table of all the instructions. Code to output a type 6412 enumerating all the instructin names. 6413 6414 * igen.c(lf_print_c_semantic): Move call to increment instruction 6415 counter so that it occures _after_ the instruction has been fully 6416 validated, was double counting illegal/invalid instructions. Add 6417 conditional so only compiled in when WITH_PROFILE enabled (enabled 6418 by default). 6419 6420 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include 6421 itable.h, count individual instruction types not just total, 6422 adjust reporting functions to output this. 6423 6424 * ppc-instructions (64 bit Load Doubleword with Update Indexed): 6425 Had 32./ instead of 31./ 6426 6427 * ppc-instructions (64 bit Store Double Word Conditional Indexed): 6428 bitrot - updated to use newer CR register operators. 6429 6430 * ppc-instructions (64bit Floating Convert from Integer 6431 Doubleword): Correct call to Round_Float(). 6432 6433 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney (a] highland.com.au> 6434 6435 * basics.h: #include "sim_callbacks.h" earlier so that its 6436 prototypes are declared in all other header files. 6437 6438 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update 6439 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into 6440 bits.h. 6441 6442 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*): 6443 Add size of buffer argument to functions writing a string into a 6444 buffer. Check for buffer overflow. 6445 6446 Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney (a] highland.com.au> 6447 6448 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing 6449 of each device. Make parameter names consistent so macros work. 6450 Use macro's in device functions. 6451 6452 * device_tree.c, devices.h, devices.c: include path to device in a 6453 devices node when creating it. 6454 6455 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'. 6456 6457 * core.c: add tracing of core-device, adjust parameter names in 6458 core functions to be consistent with those in devices*. 6459 6460 Sun Oct 15 20:33:20 1995 Andrew Cagney <cagney (a] highland.com.au> 6461 6462 * debug.h, debug.c (trace_option): New function. Parses the trace 6463 option, updating the trace array. 6464 6465 * debug.h, debug.c (trace_usage): New function. Outputs the list 6466 of all possible trace options. 6467 6468 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to 6469 parse trace options specified with the simpler -t flag. Adjust 6470 usage. 6471 6472 * FIXME: basic parsing of command line options is still duplicated 6473 by main.c and sim_calls.c 6474 6475 Thu Oct 26 10:42:28 1995 Michael Meissner <meissner (a] tiktok.cygnus.com> 6476 6477 * Makefile.in (clean): Delete *.i and *.out files. 6478 6479 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP 6480 macros for either assignment or return. Fix SWAP_8 to use a 6481 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now. 6482 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs 6483 that hardwired swapping on/off, let optimizer delete dead code. 6484 6485 * main.c (main): Add printf that we caught a signal and print out 6486 the failing address. 6487 6488 Thu Oct 19 21:43:39 1995 Fred Fish <fnf (a] fishfood.amigalib.com> 6489 6490 * Makefile.in: Remove tabs from otherwise empty line. 6491 Confuses many non-GNU versions of "make". 6492 6493 Wed Oct 18 08:51:25 1995 Michael Meissner <meissner (a] tiktok.cygnus.com> 6494 6495 * Makefile.in (clean): Delete files produced by gen. 6496 6497 Mon Oct 16 17:34:24 1995 Michael Meissner <meissner (a] tiktok.cygnus.com> 6498 6499 * gen.c (lf_print_c_semantic_function): Move counting # of 6500 instructions here so it works with caching. 6501 (gen_idecode_c): Move from here. 6502 6503 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney (a] highland.com.au> 6504 6505 * gen.c, ppc-instructions, psim.c: Fix code for generating 6506 cracking instruction cache. Delete the code that cached just the 6507 result from doing an instruction lookup - this ran slower than no 6508 cache at all. 6509 6510 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner (a] tiktok.cygnus.com> 6511 6512 * Makefile.in (gen.o): Include $(INLINE_CFLAGS). 6513 6514 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with 6515 TCL when gdb is linked with the simulator. 6516 * debug.c (ppc_trace): Ditto. 6517 * sim_calls.c (sim_open): Change trace -> ppc_trace. 6518 * main.c (main): Ditto. 6519 6520 * cpu.c (cpu_add_commas): Remove extra static. 6521 6522 Thu Oct 12 11:35:53 1995 Michael Meissner <meissner (a] tiktok.cygnus.com> 6523 6524 * Makefile.in (psim.o): Now that inlines are turned on, make 6525 psim.o depend on all sources. 6526 6527 * cpu.c (cpu_add_commas): New function to format a long with 6528 commas. 6529 (cpu_print_info): Use it to print number_of_insns. 6530 6531 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for 6532 2, 4, and 8 bytes. 6533 (ENDIAN_N): If both target and host byte orders are known, don't 6534 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER. 6535 6536 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0 6537 to allow target specific H2T_n/T2H_n macros to be used. 6538 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is 6539 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead 6540 of the 3 instruction sequence that runs on 386s. 6541 6542 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if 6543 specified on the compile line. 6544 (WITH_BSWAP): If not defined, define as 0. 6545 6546 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add 6547 default inline support. Pass INLINE_CFLAGS when compiling. 6548 6549 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not 6550 INLINE_DEVICES since GCC doesn't like inline functions that 6551 accept variable arguments. 6552 (stack_ioctl_callback): Make function just static because GCC 6553 doesn't like inline functions that accept variable arguments. 6554 6555 * devices.h (STATIC_DEVICES): Define as empty if not defined. 6556 6557 * inline.c: Correct pathnames of included C files to match current 6558 implementation. 6559 6560 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be 6561 non-zero, define STATIC_DEVICES to be static. 6562 6563 * std-config.h (INLINE): If GNU C and optimizing, define this as 6564 __inline__. 6565 (DEFAULT_INLINE): If not defined, define as 0. 6566 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE. 6567 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto. 6568 ({SPREG,IDECODE}_INLINE): Ditto. 6569 6570 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney (a] highland.com.au> 6571 6572 * ppc-instructions: Initial cut of floating point suport added. 6573 Of note include - use of host IEEE floating point instructions, 6574 use of PowerPC manual pseudo code to handle the FPSCR. It is not 6575 currently a pretty sight. 6576 6577 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c: 6578 merge into core.h, core.c, core_n.h. The type memory_map replaced 6579 with core_map. This removes a level of pointer indirection when 6580 translating an address. 6581 6582 * memory_map.h, memory_map.c, memory_map_n.h: delete. 6583 6584 * Makefile.in et.al (sorry): tweek to use new core, core_map and 6585 core.h. 6586 6587 Wed Oct 11 12:10:26 1995 Andrew Cagney <cagney (a] highland.com.au> 6588 6589 * sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to 6590 most of the other functions in sim_calls.c. 6591 6592 * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in: 6593 Add macros to better cover up `generic' code. Makes it possible 6594 to step through the generic code! 6595 6596 * vm.c, vm_n.h, Makefile.in: ditto 6597 6598 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney (a] highland.com.au> 6599 6600 * devices.h, devices.c, memory_map.h, memory_map.c: Changed 6601 callback interface so that there is a read/write buffer but no 6602 read/write_word. VEA default memory read/write handler sometimes 6603 couldn't resolve an access and of those some were for a memory 6604 fault and some were because gdb was making a bogus request. 6605 6606 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c: 6607 eliminate transfer_mode (raw or cooked) parameter from read/write 6608 buffer. 6609 6610 Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney (a] highland.com.au> 6611 6612 * ppc-instructions (fmul, fmuls): correct instruction format - had 6613 FRB instead of FRC. 6614 6615 Wed Oct 4 17:31:12 1995 Andrew Cagney <cagney (a] highland.com.au> 6616 6617 * psim.c, device_tree.h, device_tree.c, devices.c (printd_*, 6618 scand_*): new functions to parse/print fields in device names 6619 while hiding any machine dependency. 6620 6621 * devices.c, psim.c: Change the stack init code so that it is 6622 handled by a device. Arguments passed across using a device ioctl 6623 (hack). 6624 6625 * devices.h, devices.c: device ioctl callback changed to allow a 6626 variable number of arguments. This gives greater flexability and 6627 greater chance of bugs. 6628 6629 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney (a] highland.com.au> 6630 6631 * main.c (printf_filtered, error): Missing va_end() to close off 6632 variable argument use. 6633 6634 * Makefile.in (tmp-gencode): comment out hack to get around some 6635 versions of make not handling files being created as side-effects. 6636 6637 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an 6638 alternative file name to use in output files for things like #line 6639 macros. 6640 6641 Makefile.in (tmp-gencode): Use gen -n so that debug info is 6642 correct. 6643 6644 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the 6645 Makefile. 6646 6647 Sat Oct 7 22:40:59 1995 Michael Meissner <meissner (a] tiktok.cygnus.com> 6648 6649 * sim_calls.c (sim_set_callbacks): Define new function. 6650 6651 Fri Oct 6 17:23:10 1995 Michael Meissner <meissner (a] tiktok.cygnus.com> 6652 6653 * psim.c (psim_print_info): Print exit status or signal number. 6654 6655 Mon Oct 2 11:46:37 1995 Michael Meissner <meissner (a] tiktok.cygnus.com> 6656 6657 * cpu.c (struct _cpu): Add number_of_insns field to trace how many 6658 instructions are executed. 6659 (cpu_increment_number_of_insns): New function to increment the 6660 number of instructions issued. 6661 (cpu_get_number_of_insns): New function to return the number of 6662 instructions issued. 6663 (cpu_print_info): New function to print cpu related information. 6664 At present, print the number of instructions executed. 6665 6666 * gen_idecode_c: Emit call to cpu_increment_number_of_insns within 6667 idecode_issue. 6668 6669 * psim.c (psim_print_info): New function to iterate over each of 6670 the CPU's calling cpu_print_info. 6671 6672 * psim.h,cpu.h: Add new declarations. 6673 6674 * sim_calls.c (sim_open): Add argument processing to add the same 6675 switches main.c accepts for the standalone processor. 6676 (sim_close): Call psim_print_info if -I. 6677 6678 * main.c (main): Add comment saying to update sim_calls.c when 6679 adding switches. Add -I to call psim_print_info when done. 6680 (usage): Update usage message. 6681 6682 Sun Oct 1 13:52:59 1995 Michael Meissner <meissner (a] tiktok.cygnus.com> 6683 6684 * main.c (printf_filtered): Correct to match new prototype. 6685 6686 Sat Sep 30 20:47:05 1995 Michael Meissner <meissner (a] tiktok.cygnus.com> 6687 6688 * sim_callbacks.h (printf_filtered): Correct prototype. 6689 6690 Thu Sep 21 16:26:49 1995 Michael Meissner <meissner (a] tiktok.cygnus.com> 6691 6692 * device_tree.c (OEA_MEMORY_SIZE): Define if not defined to 6693 0x100000. 6694 (clayton_memory_size): Define as OEA_MEMORY_SIZE. 6695 6696 * std-config.h (WITH_TRACE): Default to 1 now. 6697 6698 * psim.c (write_stack_arguments): Don't write any stack arguments 6699 if OEA. 6700 6701 * main.c (main): Switch to using getopt. Make -p also set 6702 trace_semantics. Make -a turn on all trace flags. Make -C turn 6703 on console tracing. 6704 6705 * device_tree.c (create_option_device_node): Assume a program is 6706 OEA if the start address is < 4096, not just == 0. 6707 6708 Wed Sep 20 13:36:06 1995 Ian Lance Taylor <ian (a] cygnus.com> 6709 6710 * Makefile.in (maintainer-clean): New synonym for realclean. 6711 6712 Sun Sep 10 10:23:56 1995 Michael Tiemann <tiemann (a] axon.cygnus.com> 6713 6714 * registers.c (register_description): Add gdb synonyms for cr 6715 (cnd) and msr (ps). 6716 6717 Fri Sep 8 13:16:10 1995 Ian Lance Taylor <ian (a] cygnus.com> 6718 6719 * Makefile.in (install): Don't install in $(tooldir). 6720 6721 * configure.in: Call AC_CONFIG_HEADER. Don't try to use 6722 bfd/hosts/*.h file or bfd/config/*.mh file. Call AC_PROG_CC and 6723 AC_PROG_RANLIB. Substitute in values for CFLAGS, HDEFINES, AR, 6724 and CC_FOR_BUILD. Call AC_CHECK_HEADERS for various header files. 6725 Touch stamp.h if creating config.h. 6726 * configure: Rebuild. 6727 * config.in: New file, created by autoheader. 6728 * Makefile.in (AR): Define as @AR@. 6729 (CC): New variable, defined as @CC@. 6730 (CFLAGS): Define as @CFLAGS@. 6731 (CC_FOR_BUILD): New variable, defined as @CC_FOR_BUILD@. 6732 (RANLIB): Define as @RANLIB@. 6733 (HDEFINES, TDEFINES): New variables. 6734 (@host_makefile_frag@): Remove. 6735 (mostlyclean): Make the same as clean, not distclean. 6736 (clean): Remove config.log. 6737 (distclean): Remove config.h and stamp-h. 6738 (Makefile): Don't depend upon @frags@. Just rebuild Makefile when 6739 invoking config.status. 6740 (config.h, stamp-h): New targets. 6741 (gen, gen.o): Build with CC_FOR_BUILD, not CC. 6742 (ppc-config.h): Rename from old config.h build. 6743 * (basics.h,gen.c,ppc-endian.c,psim.c): Include ppc-config.h. 6744 6745 Fri Sep 8 09:51:03 1995 Michael Meissner <meissner (a] tiktok.cygnus.com> 6746 6747 * configure{,.in}: Don't include sysdep.h from bfd, since bfd no 6748 longer provides it. 6749 * basics.h (sysdep.h): Don't include it. 6750 * Makefile.in (BASICS_H): Remove sysdep.h. 6751 6752 Wed Sep 6 13:25:42 1995 Andrew Cagney <cagney (a] highland.com.au> 6753 6754 * core.c (core_add_data): First growth of bss was being put at 6755 wrong address (0) instead of &end. 6756 6757 * core.c (core_add_stack, core_add_data): Was not handling case 6758 where bss/stack is grown across the current end-of-{bss,stack}. 6759 6760 Wed Sep 6 00:46:10 1995 Andrew Cagney <cagney (a] highland.com.au> 6761 6762 * system.c (system_call): Fix SYS_break - was aligning bss to a 6763 page boundary instead of just an 8 byte one; On first call sbrk(0) 6764 != sbrk(0). 6765 6766 Thu Aug 24 14:48:54 1995 Michael Meissner <meissner (a] tiktok.cygnus.com> 6767 6768 * Makefile.in (install): Fix install rule. 6769 6770 Tue Aug 22 09:31:18 1995 Michael Meissner <meissner (a] tiktok.cygnus.com> 6771 6772 * system.c (system_call): Add read support. 6773 6774 * main.c (main): -t sets trace_device_tree. Correct usage message 6775 to current reality. 6776 6777 * device_tree.c (update_memory_node_for_section): Make tracing 6778 output line up. If not code or readonly, assume that the section 6779 is a data section and has read/write permissions. Add readonly 6780 support. 6781 6782 * core.c (create_core_from_addresses): Print end address in traces 6783 and make tracing output line up. 6784 6785 * Makefile.in: Rewrite from Makefile to work with the Cygnus 6786 environment, and support compiling in a different directory than 6787 the sources reside in. 6788 6789 * ppc-endian.h: Rename from endian.h so that it doesn't get 6790 confused with /usr/include/sys/endian.h on Linux. Add Linux 6791 endian support. 6792 6793 * ppc-endian.c: Rename to be consistant with ppc-endian.h. 6794 Include ppc-endian.h, not endian.h. 6795 6796 * basics.h (sysdep.h): Include sysdep.h that configure makes. 6797 Include ppc-endian.h, not endian.h. 6798 6799 * std-config.h: Rename from ppc-config. Put #ifndefs around most 6800 configuration macros, so they can be overridden via CFLAGS. By 6801 default, turn off tracing. 6802 6803 * configure.in: Clone from other simulator targets. 6804 * configure: Generate via autoconf from configure.in. 6805 6806 Sat Aug 19 09:05:32 1995 Andrew Cagney <cagney (a] highland.com.au> 6807 6808 * ppc-instructions: fix srawi (was geting XER[CA] real wrong). 6809 6810 * interrupts.c (data_storage_interrupt): allow stack to grow by 6811 upto one MB per increment. 6812 6813 * ppc-instructions: divw was computing rA / rA not rA / rB 6814 6815 * main.c (main): really stupid. Wasn't exiting with correct status 6816 6817 Fri Aug 18 00:38:01 1995 Andrew Cagney <cagney (a] highland.com.au> 6818 6819 * system.c (system_call): add system calls kill(2) and getpid(2). 6820 6821 * main.c (main): Check/return exit status when simulation 6822 finishes. 6823 6824 Thu Aug 17 14:29:18 1995 Andrew Cagney <cagney (a] highland.com.au> 6825 6826 * device_tree.c (create_option_device_node): Alignment rules (at 6827 least for the moment) now are for strict alignment only for LE OEA 6828 mode. (Because of compiler problems). 6829 6830 * system.c (system_call) SYS_exit: Wasn't exiting with correct status. 6831 6832 Thu Aug 17 01:16:38 1995 Andrew Cagney <cagney (a] highland.com.au> 6833 6834 * vm.c (DEFINE_VM_DATA_MAP_WRITE_N): For miss aligned transfer 6835 forgot to return. 6836 6837 * system.c (system_call): didn't page align break argument before 6838 determining increment break increment. 6839 6840 * psim/ppc: Re-arange entire directory structure so that 6841 everything lives in the one directory. While a pain for cleaning, 6842 makes building across multiple architectures much simpler. 6843 6844 * devices.c, device_tree.c: Added code that provides a simple 6845 illustration of how an interrupt control device could be 6846 implemented. 6847 6848 * devices.c: Added code so that the dumb console device can read 6849 (from stdin) as well as write to stdout. 6850
