4 (mono_jit_cleanup): moved mono_runtime_cleanup call after the call to
7 2003-04-05 Miguel de Icaza <miguel@ximian.com>
9 * jit.c (check_inlining): honor the NOINLING atttribute.
11 2003-03-31 Martin Baulig <martin@ximian.com>

17 MONO_DEBUGGER_EVENT_THREAD_CREATED event.
19 2003-03-13 Martin Baulig <martin@ximian.com>
21 * debug.c (_mono_debug_address_from_il_offset): Moved to
22 ../metadata/debug-mono-symfile.c
24 2003-03-07 Martin Baulig <martin@ximian.com>
26 * debug-jit.c: #include <config.h>.
28 2003-03-05 Martin Baulig <martin@ximian.com>
30 * debug-jit.c, debug-jit.h: New files. Moved all JIT-specific
33 * debug.c (mono_debug_add_method): Moved to debug-jit.c.
34 (mono_debug_handle, mono_debug_initialized): Made them global.
35 (replace_suffix): Removed, this isn't used anymore.
36 (record_line_number): Moved to debug-jit.c.
37 (debug_generate_method_lines): Moved to debug-jit.c
38 (generate_line_number): Renamed to
39 _mono_debug_generate_line_number() and made it global.
40 (debug_update_il_offsets): Moved to debug-jit.c
41 (mono_debug_get_image): Renamed to _mono_debug_get_image() and made
43 (address_from_il_offset): Renamed to
44 _mono_debug_address_from_il_offset() and made it global.
45 (il_offset_from_position): Moved to debug-jit.c
46 (lookup_method): Renamed to _mono_debug_lookup_method() and made
48 (mono_debug_add_method): Moved to debug-jit.c.
49 (mono_debug_create_notification_function): Use two new functions
50 mono_debug_codegen_breakpoint() and mono_debug_codegen_ret()
51 instead of x86_breakpoint() and x86_ret().
53 Sat Mar 1 12:36:45 CET 2003 Paolo Molaro <lupus@ximian.com>
55 * jit.c: remove unnecessary assert when inlining.
57 2003-02-17 Martin Baulig <martin@ximian.com>
59 * jit.c (mono_jit_compile_method): Don't emit a `nop' at the start
62 2003-02-14 Patrik Torstensson
64 * x86.brg: Implemented CONV_OVF_[I|U]4 (freg), this fixes the issues
65 with the "checked" keyword. Closes bugs #33421 and #35280 (JIT not mint)
67 2003-02-14 Dietmar Maurer <dietmar@ximian.com>
69 * exception.c (mono_arch_find_jit_info): better way to handle
70 situations where we have no MonoJitInfo
72 2003-02-11 Zoltan Varga <vargaz@freemail.hu>
74 * trampoline.c (arch_create_jit_trampoline): This function should
75 allways return a trampoline for managed methods. Fixes bug #29859.
77 2003-02-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
79 * debug.c: allocate debug->source_files. Fixes GLib-CRITICAL upon
82 2003-02-02 Martin Baulig <martin@ximian.com>
84 * debug.c (mono_debug_add_wrapper): Lookup the wrapper method in a
85 hash table; we need to provide the correct code_size.
87 2003-02-02 Martin Baulig <martin@ximian.com>
89 * jit.c (mono_jit_compile_method): Call mono_debug_add_wrapper()
90 to add the interncall to the symbol file.
92 * debug.c (mono_debug_add_wrapper): New public function.
94 2003-02-02 Martin Baulig <martin@ximian.com>
96 * debug.c (debug_update_il_offsets): Set the prologue end address
97 to the address of the first source line.
99 2003-01-31 Dietmar Maurer <dietmar@ximian.com>
101 * jit.c (mono_analyze_stack): use the wrapper signature if necessary
103 2003-01-31 Zoltan Varga <vargaz@freemail.hu>
105 * debug.c (mono_debug_open_image): dynamic assemblies have no debug
108 Thu Jan 30 11:07:06 CET 2003 Paolo Molaro <lupus@ximian.com>
110 * helper.c: handle MONO_TYPE_ARRAY as well.
112 2003-01-29 Dietmar Maurer <dietmar@ximian.com>
114 * jit.c (mono_analyze_stack): impl. CEE_MONO_LDNATIVEOBJ
115 (mono_analyze_stack): RETOBJ always returns native sized objects
117 2003-01-28 Zoltan Varga <vargaz@freemail.hu>
119 * x86.brg (mono_ldintftn): use <= instead of <, since the
120 interface_offsets array is max_interface_id + 1 long.
122 2003-01-28 Dietmar Maurer <dietmar@ximian.com>
124 * x86.brg (mono_ldintftn): fix from Zoltan: use max_interface_id
126 2003-01-27 Zoltan Varga <vargaz@freemail.hu>
128 * exception.c (ves_icall_get_trace): avoid crash if the exception is
131 * exception.c (ves_icall_get_trace): avoid crash on unmanaged frames.
133 2003-01-26 Martin Baulig <martin@ximian.com>
135 * debug.c (mono_debug_init): Take a boolean argument which
136 specifies whether we're running in the Mono Debugger.
138 2003-01-24 Martin Baulig <martin@ximian.com>
140 * debug.c (mono_debug_io_layer): Disable this on Windows.
142 2003-01-23 Dick Porter <dick@ximian.com>
144 * mono.c: Use mono_runtime_exec_managed_code() to run all managed
147 * jit.c: Changed thread start and attach callbacks to pass the
148 thread ID, not the MonoThread pointer. Arrange that managed code
149 execution will fail an assertion in the main thread, just to be
152 2003-01-22 Martin Baulig <martin@ximian.com>
154 * debug.c: Reverted Gonzalo's last change since it is wrong.
155 We're also using the debugging code on Windows, for instance the
156 stabs stuff when running in gdb. I hope this code still builds on
157 Windows; if not, we need to fix this.
158 Moved all the mono debugger support code into the debugger itself;
159 when debugging a managed application, the debugger new launches a
160 small unmanaged wrapper application which contains this stuff.
162 * debug.h (MonoDebuggerIOLayer): New public typedef; this is just
163 initialized to an array of function pointers to the io-layer
164 function; they don't seem to be public in the `libmono' library.
165 (mono_debugger_event): New public function. Sends the debugger an
166 event if we're running in the Mono Debugger and does nothing otherwise.
168 * mono.c: Don't initialize the Mono Debugger here.
170 * jit.c (mono_debug_insert_breakpoint): Removed, this isn't used anymore.
171 (mono_thread_start_cb, mono_thread_attach_cb): Call
172 mono_debugger_event() to send the debugger a callback.
174 2003-01-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
176 * debug.c: make all public symbols just dummy for windows.
178 2003-01-20 Miguel de Icaza <miguel@ximian.com>
180 * debug.c (initialize_debugger_support): ifdef out the call to
181 mono_debugger_init_thread_debug for the release.
183 Someone should look into why its not defined. I think the problem
184 is what Dick pointed out somewhere: code in io-layer is not
185 supposed to ever be used in Windows, so code for the debugger that
186 lives there must be moved elsewhere.
188 2003-01-19 Martin Baulig <martin@ximian.com>
190 * debug.c: Ok, this should now finally be working this time ....
192 2003-01-18 Martin Baulig <martin@ximian.com>
194 * debug.c (mono_debugger_jit_exec): Send the background thread a
195 SIGKILL before returning.
197 2003-01-17 Dietmar Maurer <dietmar@ximian.com>
199 * x86.brg: removed duplicated CONV_OVF_I4
201 2003-01-17 Martin Baulig <martin@ximian.com>
203 * debug.c: Don't use mono_once here. Reworked the API a bit to
204 use `mono_debug_' and `debug_' for the general debugging API and
205 `mono_debugger_' and `debugger_' for the Mono Debugger stuff.
207 2003-01-16 Martin Baulig <martin@ximian.com>
209 * debug.c (debugger_thread_func): We don't need to `raise
210 (SIGSTOP)' anymore; the thread manager already takes care of this.
212 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
214 * exception.c (arch_handle_exception): exclude runtime invoke
215 wrapper from the stack trace
217 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
218 (mono_thread_start_cb): save an additional LMF at thread start
220 2003-01-16 Martin Baulig <martin@ximian.com>
222 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
223 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
224 and the LinuxThreads port doesn't allow you to override the handler.
225 [FIXME: This avoids an assertion failure on startup, but there's
226 still an issue with thread termination.]
228 2003-01-16 Martin Baulig <martin@ximian.com>
230 * debug.c (debugger_thread_func): We don't need to `raise
231 (SIGSTOP)' anymore; the thread manager already takes care of this.
233 2003-01-16 Martin Baulig <martin@ximian.com>
235 * debug.c: Use the mono/io-layer functions here instead of gthread.
237 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
239 * jit.c (mono_jit_compile_method): make sure runtime_init is called
240 (mono_analyze_stack): make sure runtime_init is called
242 2003-01-14 Martin Baulig <martin@ximian.com>
244 * debug.c (debugger_update_symbol_file_table): Moved all the
245 functionality into debugger_update_symbol_file_table_internal();
246 the latter one will be called from the background thread while
247 already owning the lock. This'll allow us to step into
248 debugger_update_symbol_file_table() in the debugger and debug it.
250 2003-01-14 Martin Baulig <martin@ximian.com>
252 * Makefile.am: Link against gthread.
254 * jit.c: After realizing that mono-mutex doesn't work either
255 because it doesn't support recursive mutexes on FreeBSD, rewrote
256 the whole thread stuff to use gthread. This seems to fix this
257 weird deadlock in the debugger as well.
259 2003-01-12 Alp Toker <alp@atoker.com>
261 * exception.c: Typo fix: insinde -> inside
263 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
265 * exception.c (ves_icall_get_frame_info): skip one more frame and also
266 MONO_WRAPPER_RUNTIME_INVOKE wrappers
267 (x86_unwind_native_frame): disable unnecessary assertion
269 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
271 * exception.c (ves_icall_get_frame_info): fix bug 36382
273 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
275 * jit.c: handle wrapper_data in NEWOBJ/CALL.
277 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
279 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
281 2003-01-06 Martin Baulig <martin@ximian.com>
283 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
285 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
286 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
288 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
290 * debug.c: Move must_send_finished var declaration out of #if win32
291 block (this fixes the build on win32)
293 2003-01-05 Martin Baulig <martin@ximian.com>
295 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
296 this is used when we're running inside the Mono Debugger
297 (mono_debugger_wait): Put the waiting code into a function of its own.
299 * mono.c (main): Call mono_debugger_jit_exec() instead of
300 mono_jit_exec() if we're running inside the Mono Debugger.
302 2003-01-05 Martin Baulig <martin@ximian.com>
304 * debug.h (MonoDebugFormat): Added
305 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
306 we're running inside the Mono Debugger prior to the args parsing.
308 2003-01-04 Martin Baulig <martin@ximian.com>
310 * debug.c (release_symbol_file_table): Only call this if we're
311 actually modifying the symbol tables.
312 (mono_debug_open): Always set the `mono_debugger_class_init_func'
313 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
315 2003-01-03 Martin Baulig <martin@ximian.com>
317 * debug.c: Disable the mono debugger stuff on Windows.
319 2003-01-03 Martin Baulig <martin@ximian.com>
321 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
322 function. This is called from the breakpoint trampoline to signal
323 the debugger and wait until it has reload the symbol tables.
325 * trampoline.c (get_breakpoint_trampoline): Call the new
326 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
327 trampoline just before the breakpoint.
329 2002-12-31 Martin Baulig <martin@ximian.com>
331 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
332 field to point to the MonoGlobalSymbolTable.
334 2002-12-30 Martin Baulig <martin@ximian.com>
336 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
337 This variable now specifies that the symbol tables have been
338 modified after the last notification has been send. The debugger
339 uses this flag to check whether it needs to reload the symbol
341 (debugger_compile_method): Just send a notification to the
342 debugger, but don't set the modified flag. It may or may not be
343 set when the debugger gets the notification - depending on whether
344 the JIT compilation added a new method to the symbol tables.
346 2002-12-30 Martin Baulig <martin@ximian.com>
348 * debug.c (debugger_compile_method): This is a wrapper around
349 mono_compile_method() which always sends a notification to the
352 2002-12-30 Martin Baulig <martin@ximian.com>
354 * debug.c: Reload the symbol file table before sending the
355 notification event to the debugger.
356 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
358 2002-12-31 Martin Baulig <martin@ximian.com>
360 * debug.c: Propertly lock everything and avoid race conditions.
361 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
363 2002-12-31 Duncan Mak <duncan@ximian.com>
365 * debug.c (initialize_debugger_support): Fix build error by
366 declaring ret at the top of the function.
368 2002-12-30 Martin Baulig <martin@ximian.com>
370 * debug.c: When running under the mono debugger, create a special
371 debugger thread; always protect the symbol tables with a mutex.
373 2002-12-28 Martin Baulig <martin@ximian.com>
375 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
376 incremented each time one of the symbol tables is modified.
378 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
380 * jit.c: fix LDELEMA implementation here as well.
382 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
384 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
386 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
388 * jit.c: query the thread abort signal from the runtime.
390 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
392 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
394 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
396 * jit.c (mono_analyze_stack): call the utility function
397 mono_field_from_token to avoid code duplication.
399 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
401 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
403 * x86.brg (stmt): POP floating point stack correctly
405 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
407 * emit-x86.c (arch_emit_prologue): don't save caller saved
410 * exception.c (x86_unwind_native_frame): support exceptions inside
411 native code using gcc generated exception tables (-fexception).
413 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
415 * exception.c: include some code from Zoltan Varga, but modified
418 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
420 * exception.c: massive code cleanups. The code is still
421 architecture dependent, but it should be now possible to reuse the
422 complex parts for other architecture.
424 2002-11-15 Dick Porter <dick@ximian.com>
426 * jit.c: Pass the attach callback to mono_runtime_init().
428 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
430 * jit.c: display the domain name in trace output.
432 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
434 * x86.brg (reg): fix bug #2721
436 * jit.c (mono_runtime_install_handlers): impl.
438 2002-10-17 Martin Baulig <martin@gnome.org>
440 * debug.c (mono_debug_add_method): Make this actually work if we don't
441 have any lifetime information.
443 2002-10-15 Martin Baulig <martin@gnome.org>
445 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
447 * debug.c (generate_line_number): Small fix to make this actually
448 work for more complex things.
450 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
452 * x86.brg (freg): use fprem instead of fprem1
454 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
456 * jit.c (ves_array_element_address): added check for out of range index
457 (mono_analyze_stack): added fix for bug #31654
459 2002-10-01 Martin Baulig <martin@gnome.org>
461 * debug.c: Don't create an .il file for the dynamic symbol file.
463 2002-10-01 Martin Baulig <martin@gnome.org>
465 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
467 2002-09-27 Martin Baulig <martin@gnome.org>
469 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
471 2002-09-27 Dick Porter <dick@ximian.com>
473 * mono.c: Tell glib what the program name is, by passing it the
474 name of the managed file we're executing
476 2002-09-26 Martin Baulig <martin@gnome.org>
478 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
479 trampoline into the vtable, also use it for non-virtual methods,
480 remove the breakpoint when done.
482 2002-09-26 Martin Baulig <martin@gnome.org>
484 * debug.c (debug_load_method_lines): Block SIGCHLD while running
487 2002-09-26 Martin Baulig <martin@gnome.org>
489 * debug.c: Reworked the whole debugging stuff. We have now one
490 single `mono_debug_handle' which keeps a hashtable of
491 `AssemblyDebugInfo's (which may have different debugging formats).
492 The AssemblyDebugInfo is now created when the assembly is loaded,
493 but never when adding a class/type.
495 * mono.c: Initialize debugging stuff after corlib and the assembly
498 2002-09-25 Martin Baulig <martin@gnome.org>
500 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
501 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
503 (DebugMethodInfo): Removed `line_numbers'.
505 * debug.c: Reworked the line number generation; we're now using
506 the MonoDebugLineNumberEntry try for all debugging formats. This
507 type also includes the line number and IL offset, this allows the
508 JIT to produce better line number info: we only emit line number
509 information for source lines which actually have code.
511 2002-09-25 Martin Baulig <martin@gnome.org>
513 * debug.h: Removed external declaration of all functions which
514 should only be called from the Mono Debugger and also made them
515 static. Since the debugger gets their address from the
516 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
519 2002-09-25 Martin Baulig <martin@gnome.org>
521 Improved breakpoint support, we can now dynamically insert and
522 remove breakpoints at runtime and when called from withing the
523 Mono Debugger, we're using a special breakpoint trampoline.
525 * debug.h (mono_method_has_breakpoint): New method to check
526 whether to insert a breakpoint for a method.
527 (mono_insert_breakpoint): New method to insert a breakpoint.
528 (mono_insert_breakpoint_full): New method to insert a breakpoint,
529 takes a MonoMethodDesc.
530 (mono_remove_breakpoint): New method to remove a breakpoint.
532 * debug.c (mono_debugger_insert_breakpoint): New function for the
533 debugger. Should only be called from the debugger.
534 (mono_debugger_remove_breakpoint): Likewise.
536 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
538 * trampoline.c (get_breakpoint_trampoline): New static function to
539 create a special breakpoint trampoline for the debugger.
540 (x86_magic_trampoline): If we're running inside the Mono Debugger
541 and a breakpoint was requested for the method, generate a special
542 breakpoint trampoline.
544 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
545 to insert a breakpoint.
546 (mono_debug_last_breakpoint_address): Removed.
547 (match_debug_method): Removed, use mono_method_has_breakpoint().
549 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
551 * jit.c: reorder mono_runtime_cleanup () call since it needs the
552 engine still fully working.
554 2002-09-24 Martin Baulig <martin@gnome.org>
556 * debug.c (mono_debug_open): When we're invoked from inside the
557 Mono Debugger, set mono_debugger_class_init_func (exported in
558 metadata/class.c) to mono_add_type().
559 (mono_add_type): Call mono_debug_symfile_add_type().
561 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
563 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
564 Run finalize on domain cleanup.
565 * mono.c: call setlocale ().
566 * trampoline.c: clearer error message for invalid trampoline.
568 2002-09-21 Martin Baulig <martin@gnome.org>
570 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
571 instead of writing a byte blob.
572 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
573 (mono_debug_add_method): Incrementally add the new method to the symbol
576 * exception.c (arch_handle_exception): If we have debugging support,
577 call mono_debugger_update_symbol_file_table () as well.
579 2002-09-20 Martin Baulig <martin@gnome.org>
581 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes

635 file name argument; you can now call this before loading the assembly.
636 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
637 we now use MonoSymbolFileLineNumberEntry's and a separate address array
638 instead; splitted out all MonoSymbolFileLineNumberEntry code into
639 debug_generate_il_offsets() and debug_update_il_offsets().

1177 `const char **args' argument.
1179 * mono.c (mono_jit_assembly): Renamed to mono_jit_compile_image(), added
1180 `int verbose' argument and made it public.
1181 (mono_jit_compile_class): New public function, moved the code to compile
1182 all methods in a class here from main().
1183 (--compile): The argument can now also be an image (in `@imagename' format).
1184 Updated documentation for this command line argument.
1185 (--precompile): New command line argument to precompile an image/class/method
1186 before executing the main app. This argument can be given multiple times.

1220 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
1221 file for all assemblies. Currently, the JIT doesn't put all methods
1222 from a single assembly into a continuous region of memory. We were
1223 previously creating valid DWARF 2 files for this, but unfortunately
1224 GDB's symbol tables get messed up when it reads more than one such file.
1226 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',
1227 `next_idx', `methods', `type_hash', `source_files' and `format'

1241 (mono_debug_open_assembly_stabs): Removed.
1242 (mono_debug_close_assembly_stabs).
1244 * debug-dwarf2-plus.c: This is currently broken. :-(

1320 SHL/SHR because the tree allocator can fail otherwise
1322 * exception.c (arch_handle_exception): EIP now points to the call
1323 instruction, not to the instruction after the call. This fixes the
1324 bug reported by Linus Upson (tests/exception8.cs)

1772 2002-03-23 Martin Baulig <martin@gnome.org>
1774 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1775 to do it before the X86_CMP.
1776 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1777 (reg: CLT (lreg, lreg)): Likewise.

1891 (mono_debug_open_file): Added MonoDebugFormat argument.
1892 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1893 this function from GDB. It's now safe to call this function multiple times;
1894 it'll always write a complete debugging file.
1896 * debug.c: Splitted this file into a general part which remains in this file
1897 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1898 All public functions now call a corresponding format specific function.
1900 * debug.c: The following changes are private to debug.c:
1901 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1902 (record_line_number, debug_generate_method_lines): New private functions.
1903 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1904 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1905 mono_debug_open_assembly_dwarf2).
1906 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1907 now safe to call this function multiple times.
1908 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1909 returns an unique index for this type. It's used to ensure that we only write
1910 each class once to the debugging file.
1911 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1912 data structure, but don't directly write to the debugging file. This is done
1913 later from mono_debug_write_assembly().
1915 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1916 debugging output. Call mono_debug_close() on cleanup if necessary.
1918 2002-03-14 Martin Baulig <martin@gnome.org>
1920 * debug-private.h: New private header file.
1922 * debug-stabs.c: Added the stabs type generation stuff which was
1923 previously in debug.c.
1925 * debug-dwarf.c: Started to implement type support. We're currently
1926 only writing this most basic types to the dwarf file, but this will
1929 2002-03-13 Martin Baulig <martin@gnome.org>
1931 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1932 debugging code. They're now in CVS, but not yet used anywhere.
1934 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1936 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*

1942 * jit.c: verify that corlib and runtime are in sync.
1944 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1946 * emit-x86.c, jit.c: use the debug-helpers facilities to
1947 describe and match a method when debugging.
1949 2002-03-10 Martin Baulig <martin@gnome.org>
1951 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1952 output, put a nop instruction at the start of all functions so that
1953 the adresses won't change when using --debug.
1955 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1956 the bytecode area, stabs needs a line number in the .il file. Use the
1957 new info->moffsets to get the line number.
1958 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1959 `moffsets' is an array of `total_lines' fields (total number of lines
1960 in the .il file); for each line in the .il field, this array contains
1961 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1962 of a method and 0 otherwise.
1963 (debug_load_method_lines): Read the whole .il file and initialize the
1964 info->moffsets field.
1966 2002-03-09 Martin Baulig <martin@gnome.org>
1968 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1969 the unnecessary CDQ instruction.
