1 2003-02-02 Martin Baulig <martin@ximian.com>
3 * debug.c (debug_update_il_offsets): Set the prologue end address
4 to the address of the first source line.
6 2003-01-31 Dietmar Maurer <dietmar@ximian.com>
8 * jit.c (mono_analyze_stack): use the wrapper signature if necessary
10 2003-01-31 Zoltan Varga <vargaz@freemail.hu>
12 * debug.c (mono_debug_open_image): dynamic assemblies have no debug
15 Thu Jan 30 11:07:06 CET 2003 Paolo Molaro <lupus@ximian.com>
17 * helper.c: handle MONO_TYPE_ARRAY as well.
19 2003-01-29 Dietmar Maurer <dietmar@ximian.com>
21 * jit.c (mono_analyze_stack): impl. CEE_MONO_LDNATIVEOBJ
22 (mono_analyze_stack): RETOBJ always returns native sized objects
24 2003-01-28 Zoltan Varga <vargaz@freemail.hu>
26 * x86.brg (mono_ldintftn): use <= instead of <, since the
27 interface_offsets array is max_interface_id + 1 long.
29 2003-01-28 Dietmar Maurer <dietmar@ximian.com>
31 * x86.brg (mono_ldintftn): fix from Zoltan: use max_interface_id
33 2003-01-27 Zoltan Varga <vargaz@freemail.hu>
35 * exception.c (ves_icall_get_trace): avoid crash if the exception is
38 * exception.c (ves_icall_get_trace): avoid crash on unmanaged frames.
40 2003-01-26 Martin Baulig <martin@ximian.com>
42 * debug.c (mono_debug_init): Take a boolean argument which
43 specifies whether we're running in the Mono Debugger.
45 2003-01-24 Martin Baulig <martin@ximian.com>
47 * debug.c (mono_debug_io_layer): Disable this on Windows.
49 2003-01-23 Dick Porter <dick@ximian.com>
51 * mono.c: Use mono_runtime_exec_managed_code() to run all managed
54 * jit.c: Changed thread start and attach callbacks to pass the
55 thread ID, not the MonoThread pointer. Arrange that managed code
56 execution will fail an assertion in the main thread, just to be
59 2003-01-22 Martin Baulig <martin@ximian.com>
61 * debug.c: Reverted Gonzalo's last change since it is wrong.
62 We're also using the debugging code on Windows, for instance the
63 stabs stuff when running in gdb. I hope this code still builds on
64 Windows; if not, we need to fix this.
65 Moved all the mono debugger support code into the debugger itself;
66 when debugging a managed application, the debugger new launches a
67 small unmanaged wrapper application which contains this stuff.
69 * debug.h (MonoDebuggerIOLayer): New public typedef; this is just
70 initialized to an array of function pointers to the io-layer
71 function; they don't seem to be public in the `libmono' library.
72 (mono_debugger_event): New public function. Sends the debugger an
73 event if we're running in the Mono Debugger and does nothing otherwise.
75 * mono.c: Don't initialize the Mono Debugger here.
77 * jit.c (mono_debug_insert_breakpoint): Removed, this isn't used anymore.
78 (mono_thread_start_cb, mono_thread_attach_cb): Call
79 mono_debugger_event() to send the debugger a callback.
81 2003-01-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
83 * debug.c: make all public symbols just dummy for windows.
85 2003-01-20 Miguel de Icaza <miguel@ximian.com>
87 * debug.c (initialize_debugger_support): ifdef out the call to
88 mono_debugger_init_thread_debug for the release.
90 Someone should look into why its not defined. I think the problem
91 is what Dick pointed out somewhere: code in io-layer is not
92 supposed to ever be used in Windows, so code for the debugger that
93 lives there must be moved elsewhere.
95 2003-01-19 Martin Baulig <martin@ximian.com>
97 * debug.c: Ok, this should now finally be working this time ....
99 2003-01-18 Martin Baulig <martin@ximian.com>
101 * debug.c (mono_debugger_jit_exec): Send the background thread a
102 SIGKILL before returning.
104 2003-01-17 Dietmar Maurer <dietmar@ximian.com>
106 * x86.brg: removed duplicated CONV_OVF_I4
108 2003-01-17 Martin Baulig <martin@ximian.com>
110 * debug.c: Don't use mono_once here. Reworked the API a bit to
111 use `mono_debug_' and `debug_' for the general debugging API and
112 `mono_debugger_' and `debugger_' for the Mono Debugger stuff.
114 2003-01-16 Martin Baulig <martin@ximian.com>
116 * debug.c (debugger_thread_func): We don't need to `raise
117 (SIGSTOP)' anymore; the thread manager already takes care of this.
119 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
121 * exception.c (arch_handle_exception): exclude runtime invoke
122 wrapper from the stack trace
124 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
125 (mono_thread_start_cb): save an additional LMF at thread start
127 2003-01-16 Martin Baulig <martin@ximian.com>
129 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
130 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
131 and the LinuxThreads port doesn't allow you to override the handler.
132 [FIXME: This avoids an assertion failure on startup, but there's
133 still an issue with thread termination.]
135 2003-01-16 Martin Baulig <martin@ximian.com>
137 * debug.c (debugger_thread_func): We don't need to `raise
138 (SIGSTOP)' anymore; the thread manager already takes care of this.
140 2003-01-16 Martin Baulig <martin@ximian.com>
142 * debug.c: Use the mono/io-layer functions here instead of gthread.
144 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
146 * jit.c (mono_jit_compile_method): make sure runtime_init is called
147 (mono_analyze_stack): make sure runtime_init is called
149 2003-01-14 Martin Baulig <martin@ximian.com>
151 * debug.c (debugger_update_symbol_file_table): Moved all the
152 functionality into debugger_update_symbol_file_table_internal();
153 the latter one will be called from the background thread while
154 already owning the lock. This'll allow us to step into
155 debugger_update_symbol_file_table() in the debugger and debug it.
157 2003-01-14 Martin Baulig <martin@ximian.com>
159 * Makefile.am: Link against gthread.
161 * jit.c: After realizing that mono-mutex doesn't work either
162 because it doesn't support recursive mutexes on FreeBSD, rewrote
163 the whole thread stuff to use gthread. This seems to fix this
164 weird deadlock in the debugger as well.
166 2003-01-12 Alp Toker <alp@atoker.com>
168 * exception.c: Typo fix: insinde -> inside
170 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
172 * exception.c (ves_icall_get_frame_info): skip one more frame and also
173 MONO_WRAPPER_RUNTIME_INVOKE wrappers
174 (x86_unwind_native_frame): disable unnecessary assertion
176 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
178 * exception.c (ves_icall_get_frame_info): fix bug 36382
180 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
182 * jit.c: handle wrapper_data in NEWOBJ/CALL.
184 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
186 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
188 2003-01-06 Martin Baulig <martin@ximian.com>
190 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
192 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
193 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
195 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
197 * debug.c: Move must_send_finished var declaration out of #if win32
198 block (this fixes the build on win32)
200 2003-01-05 Martin Baulig <martin@ximian.com>
202 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
203 this is used when we're running inside the Mono Debugger
204 (mono_debugger_wait): Put the waiting code into a function of its own.
206 * mono.c (main): Call mono_debugger_jit_exec() instead of
207 mono_jit_exec() if we're running inside the Mono Debugger.
209 2003-01-05 Martin Baulig <martin@ximian.com>
211 * debug.h (MonoDebugFormat): Added
212 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
213 we're running inside the Mono Debugger prior to the args parsing.
215 2003-01-04 Martin Baulig <martin@ximian.com>
217 * debug.c (release_symbol_file_table): Only call this if we're
218 actually modifying the symbol tables.
219 (mono_debug_open): Always set the `mono_debugger_class_init_func'
220 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
222 2003-01-03 Martin Baulig <martin@ximian.com>
224 * debug.c: Disable the mono debugger stuff on Windows.
226 2003-01-03 Martin Baulig <martin@ximian.com>
228 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
229 function. This is called from the breakpoint trampoline to signal
230 the debugger and wait until it has reload the symbol tables.
232 * trampoline.c (get_breakpoint_trampoline): Call the new
233 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
234 trampoline just before the breakpoint.
236 2002-12-31 Martin Baulig <martin@ximian.com>
238 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
239 field to point to the MonoGlobalSymbolTable.
241 2002-12-30 Martin Baulig <martin@ximian.com>
243 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
244 This variable now specifies that the symbol tables have been
245 modified after the last notification has been send. The debugger
246 uses this flag to check whether it needs to reload the symbol
248 (debugger_compile_method): Just send a notification to the
249 debugger, but don't set the modified flag. It may or may not be
250 set when the debugger gets the notification - depending on whether
251 the JIT compilation added a new method to the symbol tables.
253 2002-12-30 Martin Baulig <martin@ximian.com>
255 * debug.c (debugger_compile_method): This is a wrapper around
256 mono_compile_method() which always sends a notification to the
259 2002-12-30 Martin Baulig <martin@ximian.com>
261 * debug.c: Reload the symbol file table before sending the
262 notification event to the debugger.
263 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
265 2002-12-31 Martin Baulig <martin@ximian.com>
267 * debug.c: Propertly lock everything and avoid race conditions.
268 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
270 2002-12-31 Duncan Mak <duncan@ximian.com>
272 * debug.c (initialize_debugger_support): Fix build error by
273 declaring ret at the top of the function.
275 2002-12-30 Martin Baulig <martin@ximian.com>
277 * debug.c: When running under the mono debugger, create a special
278 debugger thread; always protect the symbol tables with a mutex.
280 2002-12-28 Martin Baulig <martin@ximian.com>
282 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
283 incremented each time one of the symbol tables is modified.
285 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
287 * jit.c: fix LDELEMA implementation here as well.
289 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
291 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
293 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
295 * jit.c: query the thread abort signal from the runtime.
297 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
299 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
301 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
303 * jit.c (mono_analyze_stack): call the utility function
304 mono_field_from_token to avoid code duplication.
306 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
308 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
310 * x86.brg (stmt): POP floating point stack correctly
312 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
314 * emit-x86.c (arch_emit_prologue): don't save caller saved
317 * exception.c (x86_unwind_native_frame): support exceptions inside
318 native code using gcc generated exception tables (-fexception).
320 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
322 * exception.c: include some code from Zoltan Varga, but modified
325 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
327 * exception.c: massive code cleanups. The code is still
328 architecture dependent, but it should be now possible to reuse the
329 complex parts for other architecture.
331 2002-11-15 Dick Porter <dick@ximian.com>
333 * jit.c: Pass the attach callback to mono_runtime_init().
335 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
337 * jit.c: display the domain name in trace output.
339 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
341 * x86.brg (reg): fix bug #2721
343 * jit.c (mono_runtime_install_handlers): impl.
345 2002-10-17 Martin Baulig <martin@gnome.org>
347 * debug.c (mono_debug_add_method): Make this actually work if we don't
348 have any lifetime information.
350 2002-10-15 Martin Baulig <martin@gnome.org>
352 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
354 * debug.c (generate_line_number): Small fix to make this actually
355 work for more complex things.
357 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
359 * x86.brg (freg): use fprem instead of fprem1
361 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
363 * jit.c (ves_array_element_address): added check for out of range index
364 (mono_analyze_stack): added fix for bug #31654
366 2002-10-01 Martin Baulig <martin@gnome.org>
368 * debug.c: Don't create an .il file for the dynamic symbol file.
370 2002-10-01 Martin Baulig <martin@gnome.org>
372 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
374 2002-09-27 Martin Baulig <martin@gnome.org>
376 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
378 2002-09-27 Dick Porter <dick@ximian.com>
380 * mono.c: Tell glib what the program name is, by passing it the
381 name of the managed file we're executing
383 2002-09-26 Martin Baulig <martin@gnome.org>
385 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
386 trampoline into the vtable, also use it for non-virtual methods,
387 remove the breakpoint when done.
389 2002-09-26 Martin Baulig <martin@gnome.org>
391 * debug.c (debug_load_method_lines): Block SIGCHLD while running
394 2002-09-26 Martin Baulig <martin@gnome.org>
396 * debug.c: Reworked the whole debugging stuff. We have now one
397 single `mono_debug_handle' which keeps a hashtable of
398 `AssemblyDebugInfo's (which may have different debugging formats).
399 The AssemblyDebugInfo is now created when the assembly is loaded,
400 but never when adding a class/type.
402 * mono.c: Initialize debugging stuff after corlib and the assembly
405 2002-09-25 Martin Baulig <martin@gnome.org>
407 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
408 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
410 (DebugMethodInfo): Removed `line_numbers'.
412 * debug.c: Reworked the line number generation; we're now using
413 the MonoDebugLineNumberEntry try for all debugging formats. This
414 type also includes the line number and IL offset, this allows the
415 JIT to produce better line number info: we only emit line number
416 information for source lines which actually have code.
418 2002-09-25 Martin Baulig <martin@gnome.org>
420 * debug.h: Removed external declaration of all functions which
421 should only be called from the Mono Debugger and also made them
422 static. Since the debugger gets their address from the
423 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
426 2002-09-25 Martin Baulig <martin@gnome.org>
428 Improved breakpoint support, we can now dynamically insert and
429 remove breakpoints at runtime and when called from withing the
430 Mono Debugger, we're using a special breakpoint trampoline.
432 * debug.h (mono_method_has_breakpoint): New method to check
433 whether to insert a breakpoint for a method.
434 (mono_insert_breakpoint): New method to insert a breakpoint.
435 (mono_insert_breakpoint_full): New method to insert a breakpoint,
436 takes a MonoMethodDesc.
437 (mono_remove_breakpoint): New method to remove a breakpoint.
439 * debug.c (mono_debugger_insert_breakpoint): New function for the
440 debugger. Should only be called from the debugger.
441 (mono_debugger_remove_breakpoint): Likewise.
443 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
445 * trampoline.c (get_breakpoint_trampoline): New static function to
446 create a special breakpoint trampoline for the debugger.
447 (x86_magic_trampoline): If we're running inside the Mono Debugger
448 and a breakpoint was requested for the method, generate a special
449 breakpoint trampoline.
451 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
452 to insert a breakpoint.
453 (mono_debug_last_breakpoint_address): Removed.
454 (match_debug_method): Removed, use mono_method_has_breakpoint().
456 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
458 * jit.c: reorder mono_runtime_cleanup () call since it needs the
459 engine still fully working.
461 2002-09-24 Martin Baulig <martin@gnome.org>
463 * debug.c (mono_debug_open): When we're invoked from inside the
464 Mono Debugger, set mono_debugger_class_init_func (exported in
465 metadata/class.c) to mono_add_type().
466 (mono_add_type): Call mono_debug_symfile_add_type().
468 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
470 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
471 Run finalize on domain cleanup.
472 * mono.c: call setlocale ().
473 * trampoline.c: clearer error message for invalid trampoline.
475 2002-09-21 Martin Baulig <martin@gnome.org>
477 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
478 instead of writing a byte blob.
479 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
480 (mono_debug_add_method): Incrementally add the new method to the symbol
483 * exception.c (arch_handle_exception): If we have debugging support,
484 call mono_debugger_update_symbol_file_table () as well.
486 2002-09-20 Martin Baulig <martin@gnome.org>
488 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
489 the size of the variable.
491 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
493 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
494 iterations if we visit blocks in reverse order.
496 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
498 * jit.c (mono_analyze_stack): cleaup of the array code
500 * exception.c: added patch from Julio Merno to fix bug #30048
502 * jit.c (mono_analyze_stack): code cleanup, fix bug #29365
504 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
506 * x86.brg (LDELEMA): use x86_lea
508 2002-09-06 Martin Baulig <martin@gnome.org>
510 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
511 If you were getting random crashes when using the JIT with debugging
512 turned on, this fixes it.
514 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
516 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
518 2002-09-05 Martin Baulig <martin@gnome.org>
520 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
521 which is read by the debugger.
523 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>
525 * Makefile.am: link libmono directly into mono. Use a ld script
526 to reduce exported symbols.
528 2002-09-03 Martin Baulig <martin@gnome.org>
530 * debug.c (free_method_info): Make this actually work.
532 2002-09-03 Martin Baulig <martin@gnome.org>
534 * debug.h (MonoDebugFormat): Killed MONO_DEBUG_FORMAT_DWARF2_PLUS.
535 * debug-dwarf2-plus.c: Removed.
537 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
538 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
539 `mono_symfile' to `symfile'.
541 * debug.c (mono_debug_open): Replaced the assembly argument with a
542 file name argument; you can now call this before loading the assembly.
543 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
544 we now use MonoSymbolFileLineNumberEntry's and a separate address array
545 instead; splitted out all MonoSymbolFileLineNumberEntry code into
546 debug_generate_il_offsets() and debug_update_il_offsets().
547 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
548 created when reading the symbol file or from debug_load_method_lines().
549 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
551 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before
552 looking up an address.
554 * debug.c: Don't create the .il files for MONO_DEBUG_FORMAT_MONO.
556 * mono.c (main): Initialize debugging before loading the first assembly.
558 2002-08-28 Dick Porter <dick@ximian.com>
560 * mono.c: mono_set_rootdir() doesnt take any args now
562 * Makefile.am: Export HOST_CC for w32 builds
564 2002-08-28 Dietmar Maurer <dietmar@ximian.com>
566 * jit.c (mono_store_tree): only allocate vars if really necessary
568 2002-08-27 Martin Baulig <martin@gnome.org>
570 * debug.c: The mono symbol file is installed together with the assembly
571 it belongs to and it's used on a per-image basis.
573 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
575 * mono.c: don't use the cil-coff header outside of the loader.
577 2002-08-27 Martin Baulig <martin@gnome.org>
579 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
580 to use global variables for this since they're stored in a core file.

1128 file for all assemblies. Currently, the JIT doesn't put all methods
1129 from a single assembly into a continuous region of memory. We were
1130 previously creating valid DWARF 2 files for this, but unfortunately
1131 GDB's symbol tables get messed up when it reads more than one such file.
1133 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

1752 * debug-dwarf2.c: Added support for strings and arrays.
1754 2002-03-17 Martin Baulig <martin@gnome.org>
1756 * debug.c (mono_debug_get_type): Recursively call this for all function members
1758 (mono_debug_add_method): Don't mangle function names, this must be done by the
1759 debugger backend if the debugging format needs mangled names.
1761 * debug-dwarf2.c: Improved support for classes, added member functions.
1763 2002-03-16 Martin Baulig <martin@gnome.org>
1765 * debug.c (mono_debug_get_type): Recursively call this for all members and
1766 parent classes of a class type.
1768 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1769 since GDB doesn't like Java very much.
1771 2002-03-16 Martin Baulig <martin@gnome.org>
1773 * debug-dwarf2.c: Added support for enums.
1775 2002-03-15 Martin Baulig <martin@gnome.org>

1796 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1798 (mono_debug_open_file): Added MonoDebugFormat argument.
1799 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1800 this function from GDB. It's now safe to call this function multiple times;
1801 it'll always write a complete debugging file.
1803 * debug.c: Splitted this file into a general part which remains in this file
1804 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1805 All public functions now call a corresponding format specific function.
1807 * debug.c: The following changes are private to debug.c:
1808 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1809 (record_line_number, debug_generate_method_lines): New private functions.
1810 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1811 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1812 mono_debug_open_assembly_dwarf2).
1813 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1814 now safe to call this function multiple times.
1815 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1816 returns an unique index for this type. It's used to ensure that we only write
1817 each class once to the debugging file.
1818 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1819 data structure, but don't directly write to the debugging file. This is done
1820 later from mono_debug_write_assembly().
1822 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1823 debugging output. Call mono_debug_close() on cleanup if necessary.
1825 2002-03-14 Martin Baulig <martin@gnome.org>
1827 * debug-private.h: New private header file.
1829 * debug-stabs.c: Added the stabs type generation stuff which was
1830 previously in debug.c.
1832 * debug-dwarf.c: Started to implement type support. We're currently
1833 only writing this most basic types to the dwarf file, but this will
1836 2002-03-13 Martin Baulig <martin@gnome.org>
1838 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1839 debugging code. They're now in CVS, but not yet used anywhere.
1841 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1843 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*

1849 * jit.c: verify that corlib and runtime are in sync.
1851 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1853 * emit-x86.c, jit.c: use the debug-helpers facilities to
1854 describe and match a method when debugging.
1856 2002-03-10 Martin Baulig <martin@gnome.org>
1858 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1859 output, put a nop instruction at the start of all functions so that
1860 the adresses won't change when using --debug.
1862 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1863 the bytecode area, stabs needs a line number in the .il file. Use the
1864 new info->moffsets to get the line number.
1865 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1866 `moffsets' is an array of `total_lines' fields (total number of lines
1867 in the .il file); for each line in the .il field, this array contains
1868 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1869 of a method and 0 otherwise.
1870 (debug_load_method_lines): Read the whole .il file and initialize the
1871 info->moffsets field.
1873 2002-03-09 Martin Baulig <martin@gnome.org>
1875 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1876 the unnecessary CDQ instruction.
1878 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
