1 2003-01-27 Zoltan Varga <vargaz@freemail.hu>
3 * exception.c (ves_icall_get_trace): avoid crash if the exception is
6 * exception.c (ves_icall_get_trace): avoid crash on unmanaged frames.
8 2003-01-26 Martin Baulig <martin@ximian.com>
10 * debug.c (mono_debug_init): Take a boolean argument which
11 specifies whether we're running in the Mono Debugger.
13 2003-01-24 Martin Baulig <martin@ximian.com>
15 * debug.c (mono_debug_io_layer): Disable this on Windows.
17 2003-01-23 Dick Porter <dick@ximian.com>
19 * mono.c: Use mono_runtime_exec_managed_code() to run all managed
22 * jit.c: Changed thread start and attach callbacks to pass the
23 thread ID, not the MonoThread pointer. Arrange that managed code
24 execution will fail an assertion in the main thread, just to be
27 2003-01-22 Martin Baulig <martin@ximian.com>
29 * debug.c: Reverted Gonzalo's last change since it is wrong.
30 We're also using the debugging code on Windows, for instance the
31 stabs stuff when running in gdb. I hope this code still builds on
32 Windows; if not, we need to fix this.
33 Moved all the mono debugger support code into the debugger itself;
34 when debugging a managed application, the debugger new launches a
35 small unmanaged wrapper application which contains this stuff.
37 * debug.h (MonoDebuggerIOLayer): New public typedef; this is just
38 initialized to an array of function pointers to the io-layer
39 function; they don't seem to be public in the `libmono' library.
40 (mono_debugger_event): New public function. Sends the debugger an
41 event if we're running in the Mono Debugger and does nothing otherwise.
43 * mono.c: Don't initialize the Mono Debugger here.
45 * jit.c (mono_debug_insert_breakpoint): Removed, this isn't used anymore.
46 (mono_thread_start_cb, mono_thread_attach_cb): Call
47 mono_debugger_event() to send the debugger a callback.
49 2003-01-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
51 * debug.c: make all public symbols just dummy for windows.
53 2003-01-20 Miguel de Icaza <miguel@ximian.com>
55 * debug.c (initialize_debugger_support): ifdef out the call to
56 mono_debugger_init_thread_debug for the release.
58 Someone should look into why its not defined. I think the problem
59 is what Dick pointed out somewhere: code in io-layer is not
60 supposed to ever be used in Windows, so code for the debugger that
61 lives there must be moved elsewhere.
63 2003-01-19 Martin Baulig <martin@ximian.com>
65 * debug.c: Ok, this should now finally be working this time ....
67 2003-01-18 Martin Baulig <martin@ximian.com>
69 * debug.c (mono_debugger_jit_exec): Send the background thread a
70 SIGKILL before returning.
72 2003-01-17 Dietmar Maurer <dietmar@ximian.com>
74 * x86.brg: removed duplicated CONV_OVF_I4
76 2003-01-17 Martin Baulig <martin@ximian.com>
78 * debug.c: Don't use mono_once here. Reworked the API a bit to
79 use `mono_debug_' and `debug_' for the general debugging API and
80 `mono_debugger_' and `debugger_' for the Mono Debugger stuff.
82 2003-01-16 Martin Baulig <martin@ximian.com>
84 * debug.c (debugger_thread_func): We don't need to `raise
85 (SIGSTOP)' anymore; the thread manager already takes care of this.
87 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
89 * exception.c (arch_handle_exception): exclude runtime invoke
90 wrapper from the stack trace
92 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
93 (mono_thread_start_cb): save an additional LMF at thread start
95 2003-01-16 Martin Baulig <martin@ximian.com>
97 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
98 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
99 and the LinuxThreads port doesn't allow you to override the handler.
100 [FIXME: This avoids an assertion failure on startup, but there's
101 still an issue with thread termination.]
103 2003-01-16 Martin Baulig <martin@ximian.com>
105 * debug.c (debugger_thread_func): We don't need to `raise
106 (SIGSTOP)' anymore; the thread manager already takes care of this.
108 2003-01-16 Martin Baulig <martin@ximian.com>
110 * debug.c: Use the mono/io-layer functions here instead of gthread.
112 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
114 * jit.c (mono_jit_compile_method): make sure runtime_init is called
115 (mono_analyze_stack): make sure runtime_init is called
117 2003-01-14 Martin Baulig <martin@ximian.com>
119 * debug.c (debugger_update_symbol_file_table): Moved all the
120 functionality into debugger_update_symbol_file_table_internal();
121 the latter one will be called from the background thread while
122 already owning the lock. This'll allow us to step into
123 debugger_update_symbol_file_table() in the debugger and debug it.
125 2003-01-14 Martin Baulig <martin@ximian.com>
127 * Makefile.am: Link against gthread.
129 * jit.c: After realizing that mono-mutex doesn't work either
130 because it doesn't support recursive mutexes on FreeBSD, rewrote
131 the whole thread stuff to use gthread. This seems to fix this
132 weird deadlock in the debugger as well.
134 2003-01-12 Alp Toker <alp@atoker.com>
136 * exception.c: Typo fix: insinde -> inside
138 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
140 * exception.c (ves_icall_get_frame_info): skip one more frame and also
141 MONO_WRAPPER_RUNTIME_INVOKE wrappers
142 (x86_unwind_native_frame): disable unnecessary assertion
144 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
146 * exception.c (ves_icall_get_frame_info): fix bug 36382
148 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
150 * jit.c: handle wrapper_data in NEWOBJ/CALL.
152 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
154 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
156 2003-01-06 Martin Baulig <martin@ximian.com>
158 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
160 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
161 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
163 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
165 * debug.c: Move must_send_finished var declaration out of #if win32
166 block (this fixes the build on win32)
168 2003-01-05 Martin Baulig <martin@ximian.com>
170 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
171 this is used when we're running inside the Mono Debugger
172 (mono_debugger_wait): Put the waiting code into a function of its own.
174 * mono.c (main): Call mono_debugger_jit_exec() instead of
175 mono_jit_exec() if we're running inside the Mono Debugger.
177 2003-01-05 Martin Baulig <martin@ximian.com>
179 * debug.h (MonoDebugFormat): Added
180 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
181 we're running inside the Mono Debugger prior to the args parsing.
183 2003-01-04 Martin Baulig <martin@ximian.com>
185 * debug.c (release_symbol_file_table): Only call this if we're
186 actually modifying the symbol tables.
187 (mono_debug_open): Always set the `mono_debugger_class_init_func'
188 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
190 2003-01-03 Martin Baulig <martin@ximian.com>
192 * debug.c: Disable the mono debugger stuff on Windows.
194 2003-01-03 Martin Baulig <martin@ximian.com>
196 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
197 function. This is called from the breakpoint trampoline to signal
198 the debugger and wait until it has reload the symbol tables.
200 * trampoline.c (get_breakpoint_trampoline): Call the new
201 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
202 trampoline just before the breakpoint.
204 2002-12-31 Martin Baulig <martin@ximian.com>
206 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
207 field to point to the MonoGlobalSymbolTable.
209 2002-12-30 Martin Baulig <martin@ximian.com>
211 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
212 This variable now specifies that the symbol tables have been
213 modified after the last notification has been send. The debugger
214 uses this flag to check whether it needs to reload the symbol
216 (debugger_compile_method): Just send a notification to the
217 debugger, but don't set the modified flag. It may or may not be
218 set when the debugger gets the notification - depending on whether
219 the JIT compilation added a new method to the symbol tables.
221 2002-12-30 Martin Baulig <martin@ximian.com>
223 * debug.c (debugger_compile_method): This is a wrapper around
224 mono_compile_method() which always sends a notification to the
227 2002-12-30 Martin Baulig <martin@ximian.com>
229 * debug.c: Reload the symbol file table before sending the
230 notification event to the debugger.
231 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
233 2002-12-31 Martin Baulig <martin@ximian.com>
235 * debug.c: Propertly lock everything and avoid race conditions.
236 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
238 2002-12-31 Duncan Mak <duncan@ximian.com>
240 * debug.c (initialize_debugger_support): Fix build error by
241 declaring ret at the top of the function.
243 2002-12-30 Martin Baulig <martin@ximian.com>
245 * debug.c: When running under the mono debugger, create a special
246 debugger thread; always protect the symbol tables with a mutex.
248 2002-12-28 Martin Baulig <martin@ximian.com>
250 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
251 incremented each time one of the symbol tables is modified.
253 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
255 * jit.c: fix LDELEMA implementation here as well.
257 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
259 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
261 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
263 * jit.c: query the thread abort signal from the runtime.
265 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
267 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
269 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
271 * jit.c (mono_analyze_stack): call the utility function
272 mono_field_from_token to avoid code duplication.
274 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
276 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
278 * x86.brg (stmt): POP floating point stack correctly
280 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
282 * emit-x86.c (arch_emit_prologue): don't save caller saved
285 * exception.c (x86_unwind_native_frame): support exceptions inside
286 native code using gcc generated exception tables (-fexception).
288 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
290 * exception.c: include some code from Zoltan Varga, but modified
293 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
295 * exception.c: massive code cleanups. The code is still
296 architecture dependent, but it should be now possible to reuse the
297 complex parts for other architecture.
299 2002-11-15 Dick Porter <dick@ximian.com>
301 * jit.c: Pass the attach callback to mono_runtime_init().
303 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
305 * jit.c: display the domain name in trace output.
307 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
309 * x86.brg (reg): fix bug #2721
311 * jit.c (mono_runtime_install_handlers): impl.
313 2002-10-17 Martin Baulig <martin@gnome.org>
315 * debug.c (mono_debug_add_method): Make this actually work if we don't
316 have any lifetime information.
318 2002-10-15 Martin Baulig <martin@gnome.org>
320 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
322 * debug.c (generate_line_number): Small fix to make this actually
323 work for more complex things.
325 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
327 * x86.brg (freg): use fprem instead of fprem1
329 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
331 * jit.c (ves_array_element_address): added check for out of range index
332 (mono_analyze_stack): added fix for bug #31654
334 2002-10-01 Martin Baulig <martin@gnome.org>
336 * debug.c: Don't create an .il file for the dynamic symbol file.
338 2002-10-01 Martin Baulig <martin@gnome.org>
340 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
342 2002-09-27 Martin Baulig <martin@gnome.org>
344 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
346 2002-09-27 Dick Porter <dick@ximian.com>
348 * mono.c: Tell glib what the program name is, by passing it the
349 name of the managed file we're executing
351 2002-09-26 Martin Baulig <martin@gnome.org>
353 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
354 trampoline into the vtable, also use it for non-virtual methods,
355 remove the breakpoint when done.
357 2002-09-26 Martin Baulig <martin@gnome.org>
359 * debug.c (debug_load_method_lines): Block SIGCHLD while running
362 2002-09-26 Martin Baulig <martin@gnome.org>
364 * debug.c: Reworked the whole debugging stuff. We have now one
365 single `mono_debug_handle' which keeps a hashtable of
366 `AssemblyDebugInfo's (which may have different debugging formats).
367 The AssemblyDebugInfo is now created when the assembly is loaded,
368 but never when adding a class/type.
370 * mono.c: Initialize debugging stuff after corlib and the assembly
373 2002-09-25 Martin Baulig <martin@gnome.org>
375 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
376 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
378 (DebugMethodInfo): Removed `line_numbers'.
380 * debug.c: Reworked the line number generation; we're now using
381 the MonoDebugLineNumberEntry try for all debugging formats. This
382 type also includes the line number and IL offset, this allows the
383 JIT to produce better line number info: we only emit line number
384 information for source lines which actually have code.
386 2002-09-25 Martin Baulig <martin@gnome.org>
388 * debug.h: Removed external declaration of all functions which
389 should only be called from the Mono Debugger and also made them
390 static. Since the debugger gets their address from the
391 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
394 2002-09-25 Martin Baulig <martin@gnome.org>
396 Improved breakpoint support, we can now dynamically insert and
397 remove breakpoints at runtime and when called from withing the
398 Mono Debugger, we're using a special breakpoint trampoline.
400 * debug.h (mono_method_has_breakpoint): New method to check
401 whether to insert a breakpoint for a method.
402 (mono_insert_breakpoint): New method to insert a breakpoint.
403 (mono_insert_breakpoint_full): New method to insert a breakpoint,
404 takes a MonoMethodDesc.
405 (mono_remove_breakpoint): New method to remove a breakpoint.
407 * debug.c (mono_debugger_insert_breakpoint): New function for the
408 debugger. Should only be called from the debugger.
409 (mono_debugger_remove_breakpoint): Likewise.
411 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
413 * trampoline.c (get_breakpoint_trampoline): New static function to
414 create a special breakpoint trampoline for the debugger.
415 (x86_magic_trampoline): If we're running inside the Mono Debugger
416 and a breakpoint was requested for the method, generate a special
417 breakpoint trampoline.
419 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
420 to insert a breakpoint.
421 (mono_debug_last_breakpoint_address): Removed.
422 (match_debug_method): Removed, use mono_method_has_breakpoint().
424 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
426 * jit.c: reorder mono_runtime_cleanup () call since it needs the
427 engine still fully working.
429 2002-09-24 Martin Baulig <martin@gnome.org>
431 * debug.c (mono_debug_open): When we're invoked from inside the
432 Mono Debugger, set mono_debugger_class_init_func (exported in
433 metadata/class.c) to mono_add_type().
434 (mono_add_type): Call mono_debug_symfile_add_type().
436 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
438 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
439 Run finalize on domain cleanup.
440 * mono.c: call setlocale ().
441 * trampoline.c: clearer error message for invalid trampoline.
443 2002-09-21 Martin Baulig <martin@gnome.org>
445 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
446 instead of writing a byte blob.
447 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
448 (mono_debug_add_method): Incrementally add the new method to the symbol
451 * exception.c (arch_handle_exception): If we have debugging support,
452 call mono_debugger_update_symbol_file_table () as well.
454 2002-09-20 Martin Baulig <martin@gnome.org>
456 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
457 the size of the variable.
459 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
461 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
462 iterations if we visit blocks in reverse order.
464 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
466 * jit.c (mono_analyze_stack): cleaup of the array code
468 * exception.c: added patch from Julio Merno to fix bug #30048
470 * jit.c (mono_analyze_stack): code cleanup, fix bug #29365
472 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
474 * x86.brg (LDELEMA): use x86_lea
476 2002-09-06 Martin Baulig <martin@gnome.org>
478 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
479 If you were getting random crashes when using the JIT with debugging
480 turned on, this fixes it.
482 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
484 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
486 2002-09-05 Martin Baulig <martin@gnome.org>
488 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
489 which is read by the debugger.
491 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>
493 * Makefile.am: link libmono directly into mono. Use a ld script
494 to reduce exported symbols.
496 2002-09-03 Martin Baulig <martin@gnome.org>
498 * debug.c (free_method_info): Make this actually work.
500 2002-09-03 Martin Baulig <martin@gnome.org>
502 * debug.h (MonoDebugFormat): Killed MONO_DEBUG_FORMAT_DWARF2_PLUS.
503 * debug-dwarf2-plus.c: Removed.
505 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
506 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
507 `mono_symfile' to `symfile'.
509 * debug.c (mono_debug_open): Replaced the assembly argument with a
510 file name argument; you can now call this before loading the assembly.
511 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
512 we now use MonoSymbolFileLineNumberEntry's and a separate address array
513 instead; splitted out all MonoSymbolFileLineNumberEntry code into
514 debug_generate_il_offsets() and debug_update_il_offsets().
515 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
516 created when reading the symbol file or from debug_load_method_lines().
517 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
519 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before
520 looking up an address.
522 * debug.c: Don't create the .il files for MONO_DEBUG_FORMAT_MONO.
524 * mono.c (main): Initialize debugging before loading the first assembly.
526 2002-08-28 Dick Porter <dick@ximian.com>
528 * mono.c: mono_set_rootdir() doesnt take any args now
530 * Makefile.am: Export HOST_CC for w32 builds
532 2002-08-28 Dietmar Maurer <dietmar@ximian.com>
534 * jit.c (mono_store_tree): only allocate vars if really necessary
536 2002-08-27 Martin Baulig <martin@gnome.org>
538 * debug.c: The mono symbol file is installed together with the assembly
539 it belongs to and it's used on a per-image basis.
541 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
543 * mono.c: don't use the cil-coff header outside of the loader.
545 2002-08-27 Martin Baulig <martin@gnome.org>
547 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
548 to use global variables for this since they're stored in a core file.
549 (mono_debugger_symbol_file_table_generation): New global variable.
550 (mono_debugger_symbol_file_table): New global variable.
551 (mono_debugger_update_symbol_file_table): New global function to update
552 the symbol file table.
554 2002-08-27 Martin Baulig <martin@gnome.org>
556 * trampoline.c (mono_generic_trampoline_code): New global variable.
557 (arch_create_jit_trampoline): Use the new global variable to store the
558 generic trampoline code instead of using a static one. This allows the
559 debugger to access this variable to check whether a method is a trampoline.
561 * debug.h (mono_generic_trampoline_code): Added external declaration.
563 2002-08-27 Martin Baulig <martin@gnome.org>
565 * debug.c (MonoDebugHandle): Moved the method hash into the
566 AssemblyDebugInfo struct since we need to use a separate hash for each
569 * debug.c: Added special undocumented command line argument to create a
570 symbol file for IL files on-the-fly. In this case, we also need to create
571 the IL files and parse them.
572 (mono_debugger_internal_get_symbol_files): Return something more reasonable.
574 2002-08-26 Martin Baulig <martin@gnome.org>
576 * debug.c (mono_debugger_internal_free_symbol_files): New function.

1169 code using new runtime_invoke feature.
1171 * jit.c (mono_analyze_flow): try blocks are followed by handler
1172 blocks, so we need to add all handler blocks as succesors.

1195 SHL/SHR because the tree allocator can fail otherwise
1197 * exception.c (arch_handle_exception): EIP now points to the call
1198 instruction, not to the instruction after the call. This fixes the
1199 bug reported by Linus Upson (tests/exception8.cs)

1727 debugger backend if the debugging format needs mangled names.
1729 * debug-dwarf2.c: Improved support for classes, added member functions.
1731 2002-03-16 Martin Baulig <martin@gnome.org>
1733 * debug.c (mono_debug_get_type): Recursively call this for all members and
1734 parent classes of a class type.
1736 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1737 since GDB doesn't like Java very much.
1739 2002-03-16 Martin Baulig <martin@gnome.org>
1741 * debug-dwarf2.c: Added support for enums.
1743 2002-03-15 Martin Baulig <martin@gnome.org>

1764 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1766 (mono_debug_open_file): Added MonoDebugFormat argument.
1767 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1768 this function from GDB. It's now safe to call this function multiple times;
1769 it'll always write a complete debugging file.
1771 * debug.c: Splitted this file into a general part which remains in this file
1772 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1773 All public functions now call a corresponding format specific function.
1775 * debug.c: The following changes are private to debug.c:
1776 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1777 (record_line_number, debug_generate_method_lines): New private functions.
1778 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1779 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1780 mono_debug_open_assembly_dwarf2).
1781 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1782 now safe to call this function multiple times.
1783 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1784 returns an unique index for this type. It's used to ensure that we only write
1785 each class once to the debugging file.
1786 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1787 data structure, but don't directly write to the debugging file. This is done
1788 later from mono_debug_write_assembly().
1790 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1791 debugging output. Call mono_debug_close() on cleanup if necessary.
1793 2002-03-14 Martin Baulig <martin@gnome.org>
1795 * debug-private.h: New private header file.
1797 * debug-stabs.c: Added the stabs type generation stuff which was
1798 previously in debug.c.
1800 * debug-dwarf.c: Started to implement type support. We're currently
1801 only writing this most basic types to the dwarf file, but this will
1804 2002-03-13 Martin Baulig <martin@gnome.org>
1806 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1807 debugging code. They're now in CVS, but not yet used anywhere.
1809 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1811 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1812 macros, included new delegate code from Daniel Stodden.

1817 * jit.c: verify that corlib and runtime are in sync.
1819 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1821 * emit-x86.c, jit.c: use the debug-helpers facilities to
1822 describe and match a method when debugging.
1824 2002-03-10 Martin Baulig <martin@gnome.org>
1826 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1827 output, put a nop instruction at the start of all functions so that
1828 the adresses won't change when using --debug.
1830 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1831 the bytecode area, stabs needs a line number in the .il file. Use the
1832 new info->moffsets to get the line number.
1833 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1834 `moffsets' is an array of `total_lines' fields (total number of lines
1835 in the .il file); for each line in the .il field, this array contains
1836 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1837 of a method and 0 otherwise.
1838 (debug_load_method_lines): Read the whole .il file and initialize the
1839 info->moffsets field.
1841 2002-03-09 Martin Baulig <martin@gnome.org>
1843 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1844 the unnecessary CDQ instruction.
1846 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
