1 2003-01-19 Martin Baulig <martin@ximian.com>
3 * debug.c: Ok, this should now finally be working this time ....
5 2003-01-18 Martin Baulig <martin@ximian.com>
7 * debug.c (mono_debugger_jit_exec): Send the background thread a
8 SIGKILL before returning.
10 2003-01-17 Dietmar Maurer <dietmar@ximian.com>
12 * x86.brg: removed duplicated CONV_OVF_I4
14 2003-01-17 Martin Baulig <martin@ximian.com>
16 * debug.c: Don't use mono_once here. Reworked the API a bit to
17 use `mono_debug_' and `debug_' for the general debugging API and
18 `mono_debugger_' and `debugger_' for the Mono Debugger stuff.
20 2003-01-16 Martin Baulig <martin@ximian.com>
22 * debug.c (debugger_thread_func): We don't need to `raise
23 (SIGSTOP)' anymore; the thread manager already takes care of this.
25 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
27 * exception.c (arch_handle_exception): exclude runtime invoke
28 wrapper from the stack trace
30 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
31 (mono_thread_start_cb): save an additional LMF at thread start
33 2003-01-16 Martin Baulig <martin@ximian.com>
35 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
36 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
37 and the LinuxThreads port doesn't allow you to override the handler.
38 [FIXME: This avoids an assertion failure on startup, but there's
39 still an issue with thread termination.]
41 2003-01-16 Martin Baulig <martin@ximian.com>
43 * debug.c (debugger_thread_func): We don't need to `raise
44 (SIGSTOP)' anymore; the thread manager already takes care of this.
46 2003-01-16 Martin Baulig <martin@ximian.com>
48 * debug.c: Use the mono/io-layer functions here instead of gthread.
50 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
52 * jit.c (mono_jit_compile_method): make sure runtime_init is called
53 (mono_analyze_stack): make sure runtime_init is called
55 2003-01-14 Martin Baulig <martin@ximian.com>
57 * debug.c (debugger_update_symbol_file_table): Moved all the
58 functionality into debugger_update_symbol_file_table_internal();
59 the latter one will be called from the background thread while
60 already owning the lock. This'll allow us to step into
61 debugger_update_symbol_file_table() in the debugger and debug it.
63 2003-01-14 Martin Baulig <martin@ximian.com>
65 * Makefile.am: Link against gthread.
67 * jit.c: After realizing that mono-mutex doesn't work either
68 because it doesn't support recursive mutexes on FreeBSD, rewrote
69 the whole thread stuff to use gthread. This seems to fix this
70 weird deadlock in the debugger as well.
72 2003-01-12 Alp Toker <alp@atoker.com>
74 * exception.c: Typo fix: insinde -> inside
76 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
78 * exception.c (ves_icall_get_frame_info): skip one more frame and also
79 MONO_WRAPPER_RUNTIME_INVOKE wrappers
80 (x86_unwind_native_frame): disable unnecessary assertion
82 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
84 * exception.c (ves_icall_get_frame_info): fix bug 36382
86 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
88 * jit.c: handle wrapper_data in NEWOBJ/CALL.
90 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
92 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
94 2003-01-06 Martin Baulig <martin@ximian.com>
96 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
98 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
99 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
101 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
103 * debug.c: Move must_send_finished var declaration out of #if win32
104 block (this fixes the build on win32)
106 2003-01-05 Martin Baulig <martin@ximian.com>
108 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
109 this is used when we're running inside the Mono Debugger
110 (mono_debugger_wait): Put the waiting code into a function of its own.
112 * mono.c (main): Call mono_debugger_jit_exec() instead of
113 mono_jit_exec() if we're running inside the Mono Debugger.
115 2003-01-05 Martin Baulig <martin@ximian.com>
117 * debug.h (MonoDebugFormat): Added
118 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
119 we're running inside the Mono Debugger prior to the args parsing.
121 2003-01-04 Martin Baulig <martin@ximian.com>
123 * debug.c (release_symbol_file_table): Only call this if we're
124 actually modifying the symbol tables.
125 (mono_debug_open): Always set the `mono_debugger_class_init_func'
126 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
128 2003-01-03 Martin Baulig <martin@ximian.com>
130 * debug.c: Disable the mono debugger stuff on Windows.
132 2003-01-03 Martin Baulig <martin@ximian.com>
134 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
135 function. This is called from the breakpoint trampoline to signal
136 the debugger and wait until it has reload the symbol tables.
138 * trampoline.c (get_breakpoint_trampoline): Call the new
139 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
140 trampoline just before the breakpoint.
142 2002-12-31 Martin Baulig <martin@ximian.com>
144 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
145 field to point to the MonoGlobalSymbolTable.
147 2002-12-30 Martin Baulig <martin@ximian.com>
149 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
150 This variable now specifies that the symbol tables have been
151 modified after the last notification has been send. The debugger
152 uses this flag to check whether it needs to reload the symbol
154 (debugger_compile_method): Just send a notification to the
155 debugger, but don't set the modified flag. It may or may not be
156 set when the debugger gets the notification - depending on whether
157 the JIT compilation added a new method to the symbol tables.
159 2002-12-30 Martin Baulig <martin@ximian.com>
161 * debug.c (debugger_compile_method): This is a wrapper around
162 mono_compile_method() which always sends a notification to the
165 2002-12-30 Martin Baulig <martin@ximian.com>
167 * debug.c: Reload the symbol file table before sending the
168 notification event to the debugger.
169 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
171 2002-12-31 Martin Baulig <martin@ximian.com>
173 * debug.c: Propertly lock everything and avoid race conditions.
174 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
176 2002-12-31 Duncan Mak <duncan@ximian.com>
178 * debug.c (initialize_debugger_support): Fix build error by
179 declaring ret at the top of the function.
181 2002-12-30 Martin Baulig <martin@ximian.com>
183 * debug.c: When running under the mono debugger, create a special
184 debugger thread; always protect the symbol tables with a mutex.
186 2002-12-28 Martin Baulig <martin@ximian.com>
188 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
189 incremented each time one of the symbol tables is modified.
191 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
193 * jit.c: fix LDELEMA implementation here as well.
195 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
197 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
199 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
201 * jit.c: query the thread abort signal from the runtime.
203 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
205 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
207 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
209 * jit.c (mono_analyze_stack): call the utility function
210 mono_field_from_token to avoid code duplication.
212 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
214 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
216 * x86.brg (stmt): POP floating point stack correctly
218 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
220 * emit-x86.c (arch_emit_prologue): don't save caller saved
223 * exception.c (x86_unwind_native_frame): support exceptions inside
224 native code using gcc generated exception tables (-fexception).
226 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
228 * exception.c: include some code from Zoltan Varga, but modified
231 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
233 * exception.c: massive code cleanups. The code is still
234 architecture dependent, but it should be now possible to reuse the
235 complex parts for other architecture.
237 2002-11-15 Dick Porter <dick@ximian.com>
239 * jit.c: Pass the attach callback to mono_runtime_init().
241 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
243 * jit.c: display the domain name in trace output.
245 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
247 * x86.brg (reg): fix bug #2721
249 * jit.c (mono_runtime_install_handlers): impl.
251 2002-10-17 Martin Baulig <martin@gnome.org>
253 * debug.c (mono_debug_add_method): Make this actually work if we don't
254 have any lifetime information.
256 2002-10-15 Martin Baulig <martin@gnome.org>
258 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
260 * debug.c (generate_line_number): Small fix to make this actually
261 work for more complex things.
263 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
265 * x86.brg (freg): use fprem instead of fprem1
267 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
269 * jit.c (ves_array_element_address): added check for out of range index
270 (mono_analyze_stack): added fix for bug #31654
272 2002-10-01 Martin Baulig <martin@gnome.org>
274 * debug.c: Don't create an .il file for the dynamic symbol file.
276 2002-10-01 Martin Baulig <martin@gnome.org>
278 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
280 2002-09-27 Martin Baulig <martin@gnome.org>
282 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
284 2002-09-27 Dick Porter <dick@ximian.com>
286 * mono.c: Tell glib what the program name is, by passing it the
287 name of the managed file we're executing
289 2002-09-26 Martin Baulig <martin@gnome.org>
291 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
292 trampoline into the vtable, also use it for non-virtual methods,
293 remove the breakpoint when done.
295 2002-09-26 Martin Baulig <martin@gnome.org>
297 * debug.c (debug_load_method_lines): Block SIGCHLD while running
300 2002-09-26 Martin Baulig <martin@gnome.org>
302 * debug.c: Reworked the whole debugging stuff. We have now one
303 single `mono_debug_handle' which keeps a hashtable of
304 `AssemblyDebugInfo's (which may have different debugging formats).
305 The AssemblyDebugInfo is now created when the assembly is loaded,
306 but never when adding a class/type.
308 * mono.c: Initialize debugging stuff after corlib and the assembly
311 2002-09-25 Martin Baulig <martin@gnome.org>
313 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
314 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
316 (DebugMethodInfo): Removed `line_numbers'.
318 * debug.c: Reworked the line number generation; we're now using
319 the MonoDebugLineNumberEntry try for all debugging formats. This
320 type also includes the line number and IL offset, this allows the
321 JIT to produce better line number info: we only emit line number
322 information for source lines which actually have code.
324 2002-09-25 Martin Baulig <martin@gnome.org>
326 * debug.h: Removed external declaration of all functions which
327 should only be called from the Mono Debugger and also made them
328 static. Since the debugger gets their address from the
329 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
332 2002-09-25 Martin Baulig <martin@gnome.org>
334 Improved breakpoint support, we can now dynamically insert and
335 remove breakpoints at runtime and when called from withing the
336 Mono Debugger, we're using a special breakpoint trampoline.
338 * debug.h (mono_method_has_breakpoint): New method to check
339 whether to insert a breakpoint for a method.
340 (mono_insert_breakpoint): New method to insert a breakpoint.
341 (mono_insert_breakpoint_full): New method to insert a breakpoint,
342 takes a MonoMethodDesc.
343 (mono_remove_breakpoint): New method to remove a breakpoint.
345 * debug.c (mono_debugger_insert_breakpoint): New function for the
346 debugger. Should only be called from the debugger.
347 (mono_debugger_remove_breakpoint): Likewise.
349 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
351 * trampoline.c (get_breakpoint_trampoline): New static function to
352 create a special breakpoint trampoline for the debugger.
353 (x86_magic_trampoline): If we're running inside the Mono Debugger
354 and a breakpoint was requested for the method, generate a special
355 breakpoint trampoline.
357 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
358 to insert a breakpoint.
359 (mono_debug_last_breakpoint_address): Removed.
360 (match_debug_method): Removed, use mono_method_has_breakpoint().
362 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
364 * jit.c: reorder mono_runtime_cleanup () call since it needs the
365 engine still fully working.
367 2002-09-24 Martin Baulig <martin@gnome.org>
369 * debug.c (mono_debug_open): When we're invoked from inside the
370 Mono Debugger, set mono_debugger_class_init_func (exported in
371 metadata/class.c) to mono_add_type().
372 (mono_add_type): Call mono_debug_symfile_add_type().
374 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
376 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
377 Run finalize on domain cleanup.
378 * mono.c: call setlocale ().
379 * trampoline.c: clearer error message for invalid trampoline.
381 2002-09-21 Martin Baulig <martin@gnome.org>
383 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
384 instead of writing a byte blob.
385 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
386 (mono_debug_add_method): Incrementally add the new method to the symbol
389 * exception.c (arch_handle_exception): If we have debugging support,
390 call mono_debugger_update_symbol_file_table () as well.
392 2002-09-20 Martin Baulig <martin@gnome.org>
394 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
395 the size of the variable.
397 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
399 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
400 iterations if we visit blocks in reverse order.
402 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
404 * jit.c (mono_analyze_stack): cleaup of the array code
406 * exception.c: added patch from Julio Merno to fix bug #30048
408 * jit.c (mono_analyze_stack): code cleanup, fix bug #29365
410 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
412 * x86.brg (LDELEMA): use x86_lea
414 2002-09-06 Martin Baulig <martin@gnome.org>
416 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
417 If you were getting random crashes when using the JIT with debugging
418 turned on, this fixes it.
420 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
422 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
424 2002-09-05 Martin Baulig <martin@gnome.org>
426 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
427 which is read by the debugger.
429 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>
431 * Makefile.am: link libmono directly into mono. Use a ld script
432 to reduce exported symbols.
434 2002-09-03 Martin Baulig <martin@gnome.org>
436 * debug.c (free_method_info): Make this actually work.
438 2002-09-03 Martin Baulig <martin@gnome.org>
440 * debug.h (MonoDebugFormat): Killed MONO_DEBUG_FORMAT_DWARF2_PLUS.
441 * debug-dwarf2-plus.c: Removed.
443 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
444 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
445 `mono_symfile' to `symfile'.
447 * debug.c (mono_debug_open): Replaced the assembly argument with a
448 file name argument; you can now call this before loading the assembly.
449 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
450 we now use MonoSymbolFileLineNumberEntry's and a separate address array
451 instead; splitted out all MonoSymbolFileLineNumberEntry code into
452 debug_generate_il_offsets() and debug_update_il_offsets().
453 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
454 created when reading the symbol file or from debug_load_method_lines().
455 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
457 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before
458 looking up an address.
460 * debug.c: Don't create the .il files for MONO_DEBUG_FORMAT_MONO.
462 * mono.c (main): Initialize debugging before loading the first assembly.
464 2002-08-28 Dick Porter <dick@ximian.com>
466 * mono.c: mono_set_rootdir() doesnt take any args now
468 * Makefile.am: Export HOST_CC for w32 builds
470 2002-08-28 Dietmar Maurer <dietmar@ximian.com>
472 * jit.c (mono_store_tree): only allocate vars if really necessary
474 2002-08-27 Martin Baulig <martin@gnome.org>
476 * debug.c: The mono symbol file is installed together with the assembly
477 it belongs to and it's used on a per-image basis.
479 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
481 * mono.c: don't use the cil-coff header outside of the loader.
483 2002-08-27 Martin Baulig <martin@gnome.org>
485 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
486 to use global variables for this since they're stored in a core file.
487 (mono_debugger_symbol_file_table_generation): New global variable.
488 (mono_debugger_symbol_file_table): New global variable.
489 (mono_debugger_update_symbol_file_table): New global function to update
490 the symbol file table.
492 2002-08-27 Martin Baulig <martin@gnome.org>
494 * trampoline.c (mono_generic_trampoline_code): New global variable.
495 (arch_create_jit_trampoline): Use the new global variable to store the
496 generic trampoline code instead of using a static one. This allows the
497 debugger to access this variable to check whether a method is a trampoline.
499 * debug.h (mono_generic_trampoline_code): Added external declaration.
501 2002-08-27 Martin Baulig <martin@gnome.org>
503 * debug.c (MonoDebugHandle): Moved the method hash into the
504 AssemblyDebugInfo struct since we need to use a separate hash for each
507 * debug.c: Added special undocumented command line argument to create a
508 symbol file for IL files on-the-fly. In this case, we also need to create
509 the IL files and parse them.
510 (mono_debugger_internal_get_symbol_files): Return something more reasonable.
512 2002-08-26 Martin Baulig <martin@gnome.org>
514 * debug.c (mono_debugger_internal_free_symbol_files): New function.
515 (mono_debugger_internal_symbol_files_changed): New global variable.
517 2002-08-24 Martin Baulig <martin@gnome.org>
519 * debug.c (mono_debugger_internal_get_symbol_files): New function.
521 2002-08-24 Martin Baulig <martin@gnome.org>
523 * debug.c (mono_debug_write_symbols): Added support for the new
526 * mono.c (main): The `--debug' argument now knows about a new
527 debugging format `mono' which will be used to display source lines
530 * debug.h (MonoDebugFormat): Added a new MONO_DEBUG_FORMAT_MONO
531 which will be used when displaying backtraces. It reads a new
534 2002-08-23 Martin Baulig <martin@gnome.org>
536 * jit.c (match_debug_method): Don't include runtime invoke methods
539 * mono.c (main): Accept `Main' as argument to --break to insert a
540 breakpoint on the application's main method.
542 2002-08-23 Martin Baulig <martin@gnome.org>

546 2002-08-21 Dietmar Maurer <dietmar@ximian.com>
548 * exception.c (arch_handle_exception): don't set stack_trace to
549 null (so that it contains the full trace even when we rethrow the
552 2002-08-19 Nick Drochak <ndrochak@gol.com>
554 * x86.brg (mono_llmult_ovf): Simplified the code greatly by refactoring
555 the algebraic form we are using. This also eliminated a silly overflow
556 of the intermediate result that was causing troubles.
558 2002-08-16 Nick Drochak <ndrochak@gol.com>
560 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers
563 2002-08-15 Nick Drochak <ndrochak@gol.com>
565 * x86.brg (mono_llmult_ovf): Fix so it throws an overflow when result
566 will not fit in 64 bits. Fixes bug #27375.
568 Wed Aug 14 17:31:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
570 * exception.c: updates for API changes in metadata/.
572 2002-08-13 Dietmar Maurer <dietmar@ximian.com>
574 * jit.c (mono_jit_init): use ((gpointer)-1) as end_of_stack
575 address for the main thread.
577 2002-08-12 Dietmar Maurer <dietmar@ximian.com>
579 * jit.c (mono_analyze_stack): added support for Thread::Abort ()
581 2002-08-08 Dietmar Maurer <dietmar@ximian.com>
583 * exception.c (arch_handle_exception): simply return and let the

993 `int verbose' argument and made it public.
994 (mono_jit_compile_class): New public function, moved the code to compile

1033 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
1034 file for all assemblies. Currently, the JIT doesn't put all methods
1035 from a single assembly into a continuous region of memory. We were
1036 previously creating valid DWARF 2 files for this, but unfortunately
1037 GDB's symbol tables get messed up when it reads more than one such file.
1039 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

1055 (mono_debug_close_assembly_stabs).
1057 * debug-dwarf2-plus.c: This is currently broken. :-(

1131 store them as 32 bit integers.
1132 (mono_analyze_stack): we need to generate a temporary var for
1133 SHL/SHR because the tree allocator can fail otherwise
1135 * exception.c (arch_handle_exception): EIP now points to the call
1136 instruction, not to the instruction after the call. This fixes the
1137 bug reported by Linus Upson (tests/exception8.cs)

1507 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1508 numbers, we still need to generate the IL offsets here. Emit line numbers
1509 for `prologue_end_offset' (the first line of actual code) and

1704 (mono_debug_open_file): Added MonoDebugFormat argument.
1705 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1706 this function from GDB. It's now safe to call this function multiple times;
1707 it'll always write a complete debugging file.
1709 * debug.c: Splitted this file into a general part which remains in this file
1710 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.

1720 now safe to call this function multiple times.
1721 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1722 returns an unique index for this type. It's used to ensure that we only write
1723 each class once to the debugging file.

1772 `moffsets' is an array of `total_lines' fields (total number of lines
1773 in the .il file); for each line in the .il field, this array contains
1774 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1775 of a method and 0 otherwise.
1776 (debug_load_method_lines): Read the whole .il file and initialize the
1777 info->moffsets field.
