1 2003-01-20 Miguel de Icaza <miguel@ximian.com>
3 * debug.c (initialize_debugger_support): ifdef out the call to
4 mono_debugger_init_thread_debug for the release.
6 Someone should look into why its not defined. I think the problem
7 is what Dick pointed out somewhere: code in io-layer is not
8 supposed to ever be used in Windows, so code for the debugger that
9 lives there must be moved elsewhere.
11 2003-01-19 Martin Baulig <martin@ximian.com>
13 * debug.c: Ok, this should now finally be working this time ....
15 2003-01-18 Martin Baulig <martin@ximian.com>
17 * debug.c (mono_debugger_jit_exec): Send the background thread a
18 SIGKILL before returning.
20 2003-01-17 Dietmar Maurer <dietmar@ximian.com>
22 * x86.brg: removed duplicated CONV_OVF_I4
24 2003-01-17 Martin Baulig <martin@ximian.com>
26 * debug.c: Don't use mono_once here. Reworked the API a bit to
27 use `mono_debug_' and `debug_' for the general debugging API and
28 `mono_debugger_' and `debugger_' for the Mono Debugger stuff.
30 2003-01-16 Martin Baulig <martin@ximian.com>
32 * debug.c (debugger_thread_func): We don't need to `raise
33 (SIGSTOP)' anymore; the thread manager already takes care of this.
35 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
37 * exception.c (arch_handle_exception): exclude runtime invoke
38 wrapper from the stack trace
40 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
41 (mono_thread_start_cb): save an additional LMF at thread start
43 2003-01-16 Martin Baulig <martin@ximian.com>
45 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
46 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
47 and the LinuxThreads port doesn't allow you to override the handler.
48 [FIXME: This avoids an assertion failure on startup, but there's
49 still an issue with thread termination.]
51 2003-01-16 Martin Baulig <martin@ximian.com>
53 * debug.c (debugger_thread_func): We don't need to `raise
54 (SIGSTOP)' anymore; the thread manager already takes care of this.
56 2003-01-16 Martin Baulig <martin@ximian.com>
58 * debug.c: Use the mono/io-layer functions here instead of gthread.
60 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
62 * jit.c (mono_jit_compile_method): make sure runtime_init is called
63 (mono_analyze_stack): make sure runtime_init is called
65 2003-01-14 Martin Baulig <martin@ximian.com>
67 * debug.c (debugger_update_symbol_file_table): Moved all the
68 functionality into debugger_update_symbol_file_table_internal();
69 the latter one will be called from the background thread while
70 already owning the lock. This'll allow us to step into
71 debugger_update_symbol_file_table() in the debugger and debug it.
73 2003-01-14 Martin Baulig <martin@ximian.com>
75 * Makefile.am: Link against gthread.
77 * jit.c: After realizing that mono-mutex doesn't work either
78 because it doesn't support recursive mutexes on FreeBSD, rewrote
79 the whole thread stuff to use gthread. This seems to fix this
80 weird deadlock in the debugger as well.
82 2003-01-12 Alp Toker <alp@atoker.com>
84 * exception.c: Typo fix: insinde -> inside
86 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
88 * exception.c (ves_icall_get_frame_info): skip one more frame and also
89 MONO_WRAPPER_RUNTIME_INVOKE wrappers
90 (x86_unwind_native_frame): disable unnecessary assertion
92 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
94 * exception.c (ves_icall_get_frame_info): fix bug 36382
96 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
98 * jit.c: handle wrapper_data in NEWOBJ/CALL.
100 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
102 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
104 2003-01-06 Martin Baulig <martin@ximian.com>
106 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
108 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
109 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
111 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
113 * debug.c: Move must_send_finished var declaration out of #if win32
114 block (this fixes the build on win32)
116 2003-01-05 Martin Baulig <martin@ximian.com>
118 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
119 this is used when we're running inside the Mono Debugger
120 (mono_debugger_wait): Put the waiting code into a function of its own.
122 * mono.c (main): Call mono_debugger_jit_exec() instead of
123 mono_jit_exec() if we're running inside the Mono Debugger.
125 2003-01-05 Martin Baulig <martin@ximian.com>
127 * debug.h (MonoDebugFormat): Added
128 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
129 we're running inside the Mono Debugger prior to the args parsing.
131 2003-01-04 Martin Baulig <martin@ximian.com>
133 * debug.c (release_symbol_file_table): Only call this if we're
134 actually modifying the symbol tables.
135 (mono_debug_open): Always set the `mono_debugger_class_init_func'
136 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
138 2003-01-03 Martin Baulig <martin@ximian.com>
140 * debug.c: Disable the mono debugger stuff on Windows.
142 2003-01-03 Martin Baulig <martin@ximian.com>
144 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
145 function. This is called from the breakpoint trampoline to signal
146 the debugger and wait until it has reload the symbol tables.
148 * trampoline.c (get_breakpoint_trampoline): Call the new
149 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
150 trampoline just before the breakpoint.
152 2002-12-31 Martin Baulig <martin@ximian.com>
154 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
155 field to point to the MonoGlobalSymbolTable.
157 2002-12-30 Martin Baulig <martin@ximian.com>
159 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
160 This variable now specifies that the symbol tables have been
161 modified after the last notification has been send. The debugger
162 uses this flag to check whether it needs to reload the symbol
164 (debugger_compile_method): Just send a notification to the
165 debugger, but don't set the modified flag. It may or may not be
166 set when the debugger gets the notification - depending on whether
167 the JIT compilation added a new method to the symbol tables.
169 2002-12-30 Martin Baulig <martin@ximian.com>
171 * debug.c (debugger_compile_method): This is a wrapper around
172 mono_compile_method() which always sends a notification to the
175 2002-12-30 Martin Baulig <martin@ximian.com>
177 * debug.c: Reload the symbol file table before sending the
178 notification event to the debugger.
179 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
181 2002-12-31 Martin Baulig <martin@ximian.com>
183 * debug.c: Propertly lock everything and avoid race conditions.
184 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
186 2002-12-31 Duncan Mak <duncan@ximian.com>
188 * debug.c (initialize_debugger_support): Fix build error by
189 declaring ret at the top of the function.
191 2002-12-30 Martin Baulig <martin@ximian.com>
193 * debug.c: When running under the mono debugger, create a special
194 debugger thread; always protect the symbol tables with a mutex.
196 2002-12-28 Martin Baulig <martin@ximian.com>
198 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
199 incremented each time one of the symbol tables is modified.
201 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
203 * jit.c: fix LDELEMA implementation here as well.
205 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
207 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
209 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
211 * jit.c: query the thread abort signal from the runtime.
213 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
215 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
217 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
219 * jit.c (mono_analyze_stack): call the utility function
220 mono_field_from_token to avoid code duplication.
222 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
224 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
226 * x86.brg (stmt): POP floating point stack correctly
228 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
230 * emit-x86.c (arch_emit_prologue): don't save caller saved
233 * exception.c (x86_unwind_native_frame): support exceptions inside
234 native code using gcc generated exception tables (-fexception).
236 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
238 * exception.c: include some code from Zoltan Varga, but modified
241 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
243 * exception.c: massive code cleanups. The code is still
244 architecture dependent, but it should be now possible to reuse the
245 complex parts for other architecture.
247 2002-11-15 Dick Porter <dick@ximian.com>
249 * jit.c: Pass the attach callback to mono_runtime_init().
251 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
253 * jit.c: display the domain name in trace output.
255 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
257 * x86.brg (reg): fix bug #2721
259 * jit.c (mono_runtime_install_handlers): impl.
261 2002-10-17 Martin Baulig <martin@gnome.org>
263 * debug.c (mono_debug_add_method): Make this actually work if we don't
264 have any lifetime information.
266 2002-10-15 Martin Baulig <martin@gnome.org>
268 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
270 * debug.c (generate_line_number): Small fix to make this actually
271 work for more complex things.
273 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
275 * x86.brg (freg): use fprem instead of fprem1
277 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
279 * jit.c (ves_array_element_address): added check for out of range index
280 (mono_analyze_stack): added fix for bug #31654
282 2002-10-01 Martin Baulig <martin@gnome.org>
284 * debug.c: Don't create an .il file for the dynamic symbol file.
286 2002-10-01 Martin Baulig <martin@gnome.org>
288 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
290 2002-09-27 Martin Baulig <martin@gnome.org>
292 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
294 2002-09-27 Dick Porter <dick@ximian.com>
296 * mono.c: Tell glib what the program name is, by passing it the
297 name of the managed file we're executing
299 2002-09-26 Martin Baulig <martin@gnome.org>
301 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
302 trampoline into the vtable, also use it for non-virtual methods,
303 remove the breakpoint when done.
305 2002-09-26 Martin Baulig <martin@gnome.org>
307 * debug.c (debug_load_method_lines): Block SIGCHLD while running
310 2002-09-26 Martin Baulig <martin@gnome.org>
312 * debug.c: Reworked the whole debugging stuff. We have now one
313 single `mono_debug_handle' which keeps a hashtable of
314 `AssemblyDebugInfo's (which may have different debugging formats).
315 The AssemblyDebugInfo is now created when the assembly is loaded,
316 but never when adding a class/type.
318 * mono.c: Initialize debugging stuff after corlib and the assembly
321 2002-09-25 Martin Baulig <martin@gnome.org>
323 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
324 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
326 (DebugMethodInfo): Removed `line_numbers'.
328 * debug.c: Reworked the line number generation; we're now using
329 the MonoDebugLineNumberEntry try for all debugging formats. This
330 type also includes the line number and IL offset, this allows the
331 JIT to produce better line number info: we only emit line number
332 information for source lines which actually have code.
334 2002-09-25 Martin Baulig <martin@gnome.org>
336 * debug.h: Removed external declaration of all functions which
337 should only be called from the Mono Debugger and also made them
338 static. Since the debugger gets their address from the
339 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
342 2002-09-25 Martin Baulig <martin@gnome.org>
344 Improved breakpoint support, we can now dynamically insert and
345 remove breakpoints at runtime and when called from withing the
346 Mono Debugger, we're using a special breakpoint trampoline.
348 * debug.h (mono_method_has_breakpoint): New method to check
349 whether to insert a breakpoint for a method.
350 (mono_insert_breakpoint): New method to insert a breakpoint.
351 (mono_insert_breakpoint_full): New method to insert a breakpoint,
352 takes a MonoMethodDesc.
353 (mono_remove_breakpoint): New method to remove a breakpoint.
355 * debug.c (mono_debugger_insert_breakpoint): New function for the
356 debugger. Should only be called from the debugger.
357 (mono_debugger_remove_breakpoint): Likewise.
359 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
361 * trampoline.c (get_breakpoint_trampoline): New static function to
362 create a special breakpoint trampoline for the debugger.
363 (x86_magic_trampoline): If we're running inside the Mono Debugger
364 and a breakpoint was requested for the method, generate a special
365 breakpoint trampoline.
367 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
368 to insert a breakpoint.
369 (mono_debug_last_breakpoint_address): Removed.
370 (match_debug_method): Removed, use mono_method_has_breakpoint().
372 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
374 * jit.c: reorder mono_runtime_cleanup () call since it needs the
375 engine still fully working.
377 2002-09-24 Martin Baulig <martin@gnome.org>
379 * debug.c (mono_debug_open): When we're invoked from inside the
380 Mono Debugger, set mono_debugger_class_init_func (exported in
381 metadata/class.c) to mono_add_type().
382 (mono_add_type): Call mono_debug_symfile_add_type().
384 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
386 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
387 Run finalize on domain cleanup.
388 * mono.c: call setlocale ().
389 * trampoline.c: clearer error message for invalid trampoline.
391 2002-09-21 Martin Baulig <martin@gnome.org>
393 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
394 instead of writing a byte blob.
395 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
396 (mono_debug_add_method): Incrementally add the new method to the symbol
399 * exception.c (arch_handle_exception): If we have debugging support,
400 call mono_debugger_update_symbol_file_table () as well.
402 2002-09-20 Martin Baulig <martin@gnome.org>
404 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
405 the size of the variable.
407 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
409 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
410 iterations if we visit blocks in reverse order.
412 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
414 * jit.c (mono_analyze_stack): cleaup of the array code
416 * exception.c: added patch from Julio Merno to fix bug #30048
418 * jit.c (mono_analyze_stack): code cleanup, fix bug #29365
420 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
422 * x86.brg (LDELEMA): use x86_lea
424 2002-09-06 Martin Baulig <martin@gnome.org>
426 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
427 If you were getting random crashes when using the JIT with debugging
428 turned on, this fixes it.
430 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
432 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
434 2002-09-05 Martin Baulig <martin@gnome.org>
436 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
437 which is read by the debugger.
439 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>
441 * Makefile.am: link libmono directly into mono. Use a ld script
442 to reduce exported symbols.
444 2002-09-03 Martin Baulig <martin@gnome.org>
446 * debug.c (free_method_info): Make this actually work.
448 2002-09-03 Martin Baulig <martin@gnome.org>
450 * debug.h (MonoDebugFormat): Killed MONO_DEBUG_FORMAT_DWARF2_PLUS.
451 * debug-dwarf2-plus.c: Removed.
453 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
454 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
455 `mono_symfile' to `symfile'.
457 * debug.c (mono_debug_open): Replaced the assembly argument with a
458 file name argument; you can now call this before loading the assembly.
459 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
460 we now use MonoSymbolFileLineNumberEntry's and a separate address array
461 instead; splitted out all MonoSymbolFileLineNumberEntry code into
462 debug_generate_il_offsets() and debug_update_il_offsets().
463 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
464 created when reading the symbol file or from debug_load_method_lines().
465 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
467 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before
468 looking up an address.
470 * debug.c: Don't create the .il files for MONO_DEBUG_FORMAT_MONO.
472 * mono.c (main): Initialize debugging before loading the first assembly.
474 2002-08-28 Dick Porter <dick@ximian.com>
476 * mono.c: mono_set_rootdir() doesnt take any args now
478 * Makefile.am: Export HOST_CC for w32 builds
480 2002-08-28 Dietmar Maurer <dietmar@ximian.com>
482 * jit.c (mono_store_tree): only allocate vars if really necessary
484 2002-08-27 Martin Baulig <martin@gnome.org>
486 * debug.c: The mono symbol file is installed together with the assembly
487 it belongs to and it's used on a per-image basis.
489 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
491 * mono.c: don't use the cil-coff header outside of the loader.
493 2002-08-27 Martin Baulig <martin@gnome.org>
495 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
496 to use global variables for this since they're stored in a core file.
497 (mono_debugger_symbol_file_table_generation): New global variable.
498 (mono_debugger_symbol_file_table): New global variable.
499 (mono_debugger_update_symbol_file_table): New global function to update
500 the symbol file table.
502 2002-08-27 Martin Baulig <martin@gnome.org>
504 * trampoline.c (mono_generic_trampoline_code): New global variable.
505 (arch_create_jit_trampoline): Use the new global variable to store the
506 generic trampoline code instead of using a static one. This allows the
507 debugger to access this variable to check whether a method is a trampoline.
509 * debug.h (mono_generic_trampoline_code): Added external declaration.
511 2002-08-27 Martin Baulig <martin@gnome.org>
513 * debug.c (MonoDebugHandle): Moved the method hash into the
514 AssemblyDebugInfo struct since we need to use a separate hash for each
517 * debug.c: Added special undocumented command line argument to create a
518 symbol file for IL files on-the-fly. In this case, we also need to create
519 the IL files and parse them.
520 (mono_debugger_internal_get_symbol_files): Return something more reasonable.
522 2002-08-26 Martin Baulig <martin@gnome.org>
524 * debug.c (mono_debugger_internal_free_symbol_files): New function.
525 (mono_debugger_internal_symbol_files_changed): New global variable.
527 2002-08-24 Martin Baulig <martin@gnome.org>
529 * debug.c (mono_debugger_internal_get_symbol_files): New function.
531 2002-08-24 Martin Baulig <martin@gnome.org>
533 * debug.c (mono_debug_write_symbols): Added support for the new
536 * mono.c (main): The `--debug' argument now knows about a new
537 debugging format `mono' which will be used to display source lines
540 * debug.h (MonoDebugFormat): Added a new MONO_DEBUG_FORMAT_MONO
541 which will be used when displaying backtraces. It reads a new
544 2002-08-23 Martin Baulig <martin@gnome.org>
546 * jit.c (match_debug_method): Don't include runtime invoke methods
549 * mono.c (main): Accept `Main' as argument to --break to insert a
550 breakpoint on the application's main method.
552 2002-08-23 Martin Baulig <martin@gnome.org>
554 * debug-dwarf2.c (dwarf2_write_class_field): Don't include any static fields.
556 2002-08-21 Dietmar Maurer <dietmar@ximian.com>
558 * exception.c (arch_handle_exception): don't set stack_trace to
559 null (so that it contains the full trace even when we rethrow the
562 2002-08-19 Nick Drochak <ndrochak@gol.com>
564 * x86.brg (mono_llmult_ovf): Simplified the code greatly by refactoring
565 the algebraic form we are using. This also eliminated a silly overflow
566 of the intermediate result that was causing troubles.
568 2002-08-16 Nick Drochak <ndrochak@gol.com>
570 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers
573 2002-08-15 Nick Drochak <ndrochak@gol.com>
575 * x86.brg (mono_llmult_ovf): Fix so it throws an overflow when result
576 will not fit in 64 bits. Fixes bug #27375.
578 Wed Aug 14 17:31:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
580 * exception.c: updates for API changes in metadata/.
582 2002-08-13 Dietmar Maurer <dietmar@ximian.com>

1043 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
1044 file for all assemblies. Currently, the JIT doesn't put all methods
1045 from a single assembly into a continuous region of memory. We were
1046 previously creating valid DWARF 2 files for this, but unfortunately
1047 GDB's symbol tables get messed up when it reads more than one such file.
1049 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

1064 (mono_debug_open_assembly_stabs): Removed.
1065 (mono_debug_close_assembly_stabs).
1067 * debug-dwarf2-plus.c: This is currently broken. :-(

1141 store them as 32 bit integers.
1142 (mono_analyze_stack): we need to generate a temporary var for
1143 SHL/SHR because the tree allocator can fail otherwise
1145 * exception.c (arch_handle_exception): EIP now points to the call
1146 instruction, not to the instruction after the call. This fixes the
1147 bug reported by Linus Upson (tests/exception8.cs)

1728 mono_debug_open_assembly_dwarf2).
1729 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1730 now safe to call this function multiple times.
1731 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1732 returns an unique index for this type. It's used to ensure that we only write
1733 each class once to the debugging file.
1734 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1735 data structure, but don't directly write to the debugging file. This is done
1736 later from mono_debug_write_assembly().
1738 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1739 debugging output. Call mono_debug_close() on cleanup if necessary.

1778 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1779 the bytecode area, stabs needs a line number in the .il file. Use the
1780 new info->moffsets to get the line number.
1781 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1782 `moffsets' is an array of `total_lines' fields (total number of lines
1783 in the .il file); for each line in the .il field, this array contains
1784 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1785 of a method and 0 otherwise.
1786 (debug_load_method_lines): Read the whole .il file and initialize the
1787 info->moffsets field.
