1 2003-01-28 Dietmar Maurer <dietmar@ximian.com>
3 * x86.brg (mono_ldintftn): fix from Zoltan: use max_interface_id
5 2003-01-27 Zoltan Varga <vargaz@freemail.hu>
7 * exception.c (ves_icall_get_trace): avoid crash if the exception is
10 * exception.c (ves_icall_get_trace): avoid crash on unmanaged frames.
12 2003-01-26 Martin Baulig <martin@ximian.com>
14 * debug.c (mono_debug_init): Take a boolean argument which
15 specifies whether we're running in the Mono Debugger.
17 2003-01-24 Martin Baulig <martin@ximian.com>
19 * debug.c (mono_debug_io_layer): Disable this on Windows.
21 2003-01-23 Dick Porter <dick@ximian.com>
23 * mono.c: Use mono_runtime_exec_managed_code() to run all managed
26 * jit.c: Changed thread start and attach callbacks to pass the
27 thread ID, not the MonoThread pointer. Arrange that managed code
28 execution will fail an assertion in the main thread, just to be
31 2003-01-22 Martin Baulig <martin@ximian.com>
33 * debug.c: Reverted Gonzalo's last change since it is wrong.
34 We're also using the debugging code on Windows, for instance the
35 stabs stuff when running in gdb. I hope this code still builds on
36 Windows; if not, we need to fix this.
37 Moved all the mono debugger support code into the debugger itself;
38 when debugging a managed application, the debugger new launches a
39 small unmanaged wrapper application which contains this stuff.
41 * debug.h (MonoDebuggerIOLayer): New public typedef; this is just
42 initialized to an array of function pointers to the io-layer
43 function; they don't seem to be public in the `libmono' library.
44 (mono_debugger_event): New public function. Sends the debugger an
45 event if we're running in the Mono Debugger and does nothing otherwise.
47 * mono.c: Don't initialize the Mono Debugger here.
49 * jit.c (mono_debug_insert_breakpoint): Removed, this isn't used anymore.
50 (mono_thread_start_cb, mono_thread_attach_cb): Call
51 mono_debugger_event() to send the debugger a callback.
53 2003-01-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
55 * debug.c: make all public symbols just dummy for windows.
57 2003-01-20 Miguel de Icaza <miguel@ximian.com>
59 * debug.c (initialize_debugger_support): ifdef out the call to
60 mono_debugger_init_thread_debug for the release.
62 Someone should look into why its not defined. I think the problem
63 is what Dick pointed out somewhere: code in io-layer is not
64 supposed to ever be used in Windows, so code for the debugger that
65 lives there must be moved elsewhere.
67 2003-01-19 Martin Baulig <martin@ximian.com>
69 * debug.c: Ok, this should now finally be working this time ....
71 2003-01-18 Martin Baulig <martin@ximian.com>
73 * debug.c (mono_debugger_jit_exec): Send the background thread a
74 SIGKILL before returning.
76 2003-01-17 Dietmar Maurer <dietmar@ximian.com>
78 * x86.brg: removed duplicated CONV_OVF_I4
80 2003-01-17 Martin Baulig <martin@ximian.com>
82 * debug.c: Don't use mono_once here. Reworked the API a bit to
83 use `mono_debug_' and `debug_' for the general debugging API and
84 `mono_debugger_' and `debugger_' for the Mono Debugger stuff.
86 2003-01-16 Martin Baulig <martin@ximian.com>
88 * debug.c (debugger_thread_func): We don't need to `raise
89 (SIGSTOP)' anymore; the thread manager already takes care of this.
91 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
93 * exception.c (arch_handle_exception): exclude runtime invoke
94 wrapper from the stack trace
96 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
97 (mono_thread_start_cb): save an additional LMF at thread start
99 2003-01-16 Martin Baulig <martin@ximian.com>
101 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
102 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
103 and the LinuxThreads port doesn't allow you to override the handler.
104 [FIXME: This avoids an assertion failure on startup, but there's
105 still an issue with thread termination.]
107 2003-01-16 Martin Baulig <martin@ximian.com>
109 * debug.c (debugger_thread_func): We don't need to `raise
110 (SIGSTOP)' anymore; the thread manager already takes care of this.
112 2003-01-16 Martin Baulig <martin@ximian.com>
114 * debug.c: Use the mono/io-layer functions here instead of gthread.
116 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
118 * jit.c (mono_jit_compile_method): make sure runtime_init is called
119 (mono_analyze_stack): make sure runtime_init is called
121 2003-01-14 Martin Baulig <martin@ximian.com>
123 * debug.c (debugger_update_symbol_file_table): Moved all the
124 functionality into debugger_update_symbol_file_table_internal();
125 the latter one will be called from the background thread while
126 already owning the lock. This'll allow us to step into
127 debugger_update_symbol_file_table() in the debugger and debug it.
129 2003-01-14 Martin Baulig <martin@ximian.com>
131 * Makefile.am: Link against gthread.
133 * jit.c: After realizing that mono-mutex doesn't work either
134 because it doesn't support recursive mutexes on FreeBSD, rewrote
135 the whole thread stuff to use gthread. This seems to fix this
136 weird deadlock in the debugger as well.
138 2003-01-12 Alp Toker <alp@atoker.com>
140 * exception.c: Typo fix: insinde -> inside
142 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
144 * exception.c (ves_icall_get_frame_info): skip one more frame and also
145 MONO_WRAPPER_RUNTIME_INVOKE wrappers
146 (x86_unwind_native_frame): disable unnecessary assertion
148 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
150 * exception.c (ves_icall_get_frame_info): fix bug 36382
152 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
154 * jit.c: handle wrapper_data in NEWOBJ/CALL.
156 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
158 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
160 2003-01-06 Martin Baulig <martin@ximian.com>
162 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
164 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
165 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
167 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
169 * debug.c: Move must_send_finished var declaration out of #if win32
170 block (this fixes the build on win32)
172 2003-01-05 Martin Baulig <martin@ximian.com>
174 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
175 this is used when we're running inside the Mono Debugger
176 (mono_debugger_wait): Put the waiting code into a function of its own.
178 * mono.c (main): Call mono_debugger_jit_exec() instead of
179 mono_jit_exec() if we're running inside the Mono Debugger.
181 2003-01-05 Martin Baulig <martin@ximian.com>
183 * debug.h (MonoDebugFormat): Added
184 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
185 we're running inside the Mono Debugger prior to the args parsing.
187 2003-01-04 Martin Baulig <martin@ximian.com>
189 * debug.c (release_symbol_file_table): Only call this if we're
190 actually modifying the symbol tables.
191 (mono_debug_open): Always set the `mono_debugger_class_init_func'
192 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
194 2003-01-03 Martin Baulig <martin@ximian.com>
196 * debug.c: Disable the mono debugger stuff on Windows.
198 2003-01-03 Martin Baulig <martin@ximian.com>
200 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
201 function. This is called from the breakpoint trampoline to signal
202 the debugger and wait until it has reload the symbol tables.
204 * trampoline.c (get_breakpoint_trampoline): Call the new
205 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
206 trampoline just before the breakpoint.
208 2002-12-31 Martin Baulig <martin@ximian.com>
210 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
211 field to point to the MonoGlobalSymbolTable.
213 2002-12-30 Martin Baulig <martin@ximian.com>
215 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
216 This variable now specifies that the symbol tables have been
217 modified after the last notification has been send. The debugger
218 uses this flag to check whether it needs to reload the symbol
220 (debugger_compile_method): Just send a notification to the
221 debugger, but don't set the modified flag. It may or may not be
222 set when the debugger gets the notification - depending on whether
223 the JIT compilation added a new method to the symbol tables.
225 2002-12-30 Martin Baulig <martin@ximian.com>
227 * debug.c (debugger_compile_method): This is a wrapper around
228 mono_compile_method() which always sends a notification to the
231 2002-12-30 Martin Baulig <martin@ximian.com>
233 * debug.c: Reload the symbol file table before sending the
234 notification event to the debugger.
235 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
237 2002-12-31 Martin Baulig <martin@ximian.com>
239 * debug.c: Propertly lock everything and avoid race conditions.
240 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
242 2002-12-31 Duncan Mak <duncan@ximian.com>
244 * debug.c (initialize_debugger_support): Fix build error by
245 declaring ret at the top of the function.
247 2002-12-30 Martin Baulig <martin@ximian.com>
249 * debug.c: When running under the mono debugger, create a special
250 debugger thread; always protect the symbol tables with a mutex.
252 2002-12-28 Martin Baulig <martin@ximian.com>
254 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
255 incremented each time one of the symbol tables is modified.
257 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
259 * jit.c: fix LDELEMA implementation here as well.
261 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
263 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
265 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
267 * jit.c: query the thread abort signal from the runtime.
269 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
271 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
273 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
275 * jit.c (mono_analyze_stack): call the utility function
276 mono_field_from_token to avoid code duplication.
278 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
280 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
282 * x86.brg (stmt): POP floating point stack correctly
284 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
286 * emit-x86.c (arch_emit_prologue): don't save caller saved
289 * exception.c (x86_unwind_native_frame): support exceptions inside
290 native code using gcc generated exception tables (-fexception).
292 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
294 * exception.c: include some code from Zoltan Varga, but modified
297 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
299 * exception.c: massive code cleanups. The code is still
300 architecture dependent, but it should be now possible to reuse the
301 complex parts for other architecture.
303 2002-11-15 Dick Porter <dick@ximian.com>
305 * jit.c: Pass the attach callback to mono_runtime_init().
307 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
309 * jit.c: display the domain name in trace output.
311 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
313 * x86.brg (reg): fix bug #2721
315 * jit.c (mono_runtime_install_handlers): impl.
317 2002-10-17 Martin Baulig <martin@gnome.org>
319 * debug.c (mono_debug_add_method): Make this actually work if we don't
320 have any lifetime information.
322 2002-10-15 Martin Baulig <martin@gnome.org>
324 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
326 * debug.c (generate_line_number): Small fix to make this actually
327 work for more complex things.
329 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
331 * x86.brg (freg): use fprem instead of fprem1
333 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
335 * jit.c (ves_array_element_address): added check for out of range index
336 (mono_analyze_stack): added fix for bug #31654
338 2002-10-01 Martin Baulig <martin@gnome.org>
340 * debug.c: Don't create an .il file for the dynamic symbol file.
342 2002-10-01 Martin Baulig <martin@gnome.org>
344 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
346 2002-09-27 Martin Baulig <martin@gnome.org>
348 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
350 2002-09-27 Dick Porter <dick@ximian.com>
352 * mono.c: Tell glib what the program name is, by passing it the
353 name of the managed file we're executing
355 2002-09-26 Martin Baulig <martin@gnome.org>
357 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
358 trampoline into the vtable, also use it for non-virtual methods,
359 remove the breakpoint when done.
361 2002-09-26 Martin Baulig <martin@gnome.org>
363 * debug.c (debug_load_method_lines): Block SIGCHLD while running
366 2002-09-26 Martin Baulig <martin@gnome.org>
368 * debug.c: Reworked the whole debugging stuff. We have now one
369 single `mono_debug_handle' which keeps a hashtable of
370 `AssemblyDebugInfo's (which may have different debugging formats).
371 The AssemblyDebugInfo is now created when the assembly is loaded,
372 but never when adding a class/type.
374 * mono.c: Initialize debugging stuff after corlib and the assembly
377 2002-09-25 Martin Baulig <martin@gnome.org>
379 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
380 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
382 (DebugMethodInfo): Removed `line_numbers'.
384 * debug.c: Reworked the line number generation; we're now using
385 the MonoDebugLineNumberEntry try for all debugging formats. This
386 type also includes the line number and IL offset, this allows the
387 JIT to produce better line number info: we only emit line number
388 information for source lines which actually have code.
390 2002-09-25 Martin Baulig <martin@gnome.org>
392 * debug.h: Removed external declaration of all functions which
393 should only be called from the Mono Debugger and also made them
394 static. Since the debugger gets their address from the
395 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
398 2002-09-25 Martin Baulig <martin@gnome.org>
400 Improved breakpoint support, we can now dynamically insert and
401 remove breakpoints at runtime and when called from withing the
402 Mono Debugger, we're using a special breakpoint trampoline.
404 * debug.h (mono_method_has_breakpoint): New method to check
405 whether to insert a breakpoint for a method.
406 (mono_insert_breakpoint): New method to insert a breakpoint.
407 (mono_insert_breakpoint_full): New method to insert a breakpoint,
408 takes a MonoMethodDesc.
409 (mono_remove_breakpoint): New method to remove a breakpoint.
411 * debug.c (mono_debugger_insert_breakpoint): New function for the
412 debugger. Should only be called from the debugger.
413 (mono_debugger_remove_breakpoint): Likewise.
415 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
417 * trampoline.c (get_breakpoint_trampoline): New static function to
418 create a special breakpoint trampoline for the debugger.
419 (x86_magic_trampoline): If we're running inside the Mono Debugger
420 and a breakpoint was requested for the method, generate a special
421 breakpoint trampoline.
423 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
424 to insert a breakpoint.
425 (mono_debug_last_breakpoint_address): Removed.
426 (match_debug_method): Removed, use mono_method_has_breakpoint().
428 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
430 * jit.c: reorder mono_runtime_cleanup () call since it needs the
431 engine still fully working.
433 2002-09-24 Martin Baulig <martin@gnome.org>
435 * debug.c (mono_debug_open): When we're invoked from inside the
436 Mono Debugger, set mono_debugger_class_init_func (exported in
437 metadata/class.c) to mono_add_type().
438 (mono_add_type): Call mono_debug_symfile_add_type().
440 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
442 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
443 Run finalize on domain cleanup.
444 * mono.c: call setlocale ().
445 * trampoline.c: clearer error message for invalid trampoline.
447 2002-09-21 Martin Baulig <martin@gnome.org>
449 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
450 instead of writing a byte blob.
451 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
452 (mono_debug_add_method): Incrementally add the new method to the symbol
455 * exception.c (arch_handle_exception): If we have debugging support,
456 call mono_debugger_update_symbol_file_table () as well.
458 2002-09-20 Martin Baulig <martin@gnome.org>
460 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
461 the size of the variable.
463 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
465 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
466 iterations if we visit blocks in reverse order.
468 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
470 * jit.c (mono_analyze_stack): cleaup of the array code
472 * exception.c: added patch from Julio Merno to fix bug #30048
474 * jit.c (mono_analyze_stack): code cleanup, fix bug #29365
476 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
478 * x86.brg (LDELEMA): use x86_lea
480 2002-09-06 Martin Baulig <martin@gnome.org>
482 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
483 If you were getting random crashes when using the JIT with debugging
484 turned on, this fixes it.
486 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
488 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
490 2002-09-05 Martin Baulig <martin@gnome.org>
492 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
493 which is read by the debugger.
495 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>
497 * Makefile.am: link libmono directly into mono. Use a ld script
498 to reduce exported symbols.
500 2002-09-03 Martin Baulig <martin@gnome.org>
502 * debug.c (free_method_info): Make this actually work.
504 2002-09-03 Martin Baulig <martin@gnome.org>
506 * debug.h (MonoDebugFormat): Killed MONO_DEBUG_FORMAT_DWARF2_PLUS.
507 * debug-dwarf2-plus.c: Removed.
509 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
510 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
511 `mono_symfile' to `symfile'.
513 * debug.c (mono_debug_open): Replaced the assembly argument with a
514 file name argument; you can now call this before loading the assembly.
515 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
516 we now use MonoSymbolFileLineNumberEntry's and a separate address array
517 instead; splitted out all MonoSymbolFileLineNumberEntry code into
518 debug_generate_il_offsets() and debug_update_il_offsets().
519 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
520 created when reading the symbol file or from debug_load_method_lines().
521 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
523 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before
524 looking up an address.
526 * debug.c: Don't create the .il files for MONO_DEBUG_FORMAT_MONO.
528 * mono.c (main): Initialize debugging before loading the first assembly.
530 2002-08-28 Dick Porter <dick@ximian.com>
532 * mono.c: mono_set_rootdir() doesnt take any args now
534 * Makefile.am: Export HOST_CC for w32 builds
536 2002-08-28 Dietmar Maurer <dietmar@ximian.com>
538 * jit.c (mono_store_tree): only allocate vars if really necessary
540 2002-08-27 Martin Baulig <martin@gnome.org>
542 * debug.c: The mono symbol file is installed together with the assembly
543 it belongs to and it's used on a per-image basis.
545 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
547 * mono.c: don't use the cil-coff header outside of the loader.
549 2002-08-27 Martin Baulig <martin@gnome.org>
551 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
552 to use global variables for this since they're stored in a core file.
553 (mono_debugger_symbol_file_table_generation): New global variable.
554 (mono_debugger_symbol_file_table): New global variable.
555 (mono_debugger_update_symbol_file_table): New global function to update
556 the symbol file table.
558 2002-08-27 Martin Baulig <martin@gnome.org>
560 * trampoline.c (mono_generic_trampoline_code): New global variable.
561 (arch_create_jit_trampoline): Use the new global variable to store the
562 generic trampoline code instead of using a static one. This allows the
563 debugger to access this variable to check whether a method is a trampoline.
565 * debug.h (mono_generic_trampoline_code): Added external declaration.
567 2002-08-27 Martin Baulig <martin@gnome.org>
569 * debug.c (MonoDebugHandle): Moved the method hash into the
570 AssemblyDebugInfo struct since we need to use a separate hash for each
573 * debug.c: Added special undocumented command line argument to create a
574 symbol file for IL files on-the-fly. In this case, we also need to create
575 the IL files and parse them.
576 (mono_debugger_internal_get_symbol_files): Return something more reasonable.

1201 * exception.c (arch_handle_exception): EIP now points to the call
1202 instruction, not to the instruction after the call. This fixes the

1728 * debug.c (mono_debug_get_type): Recursively call this for all function members
1730 (mono_debug_add_method): Don't mangle function names, this must be done by the
1731 debugger backend if the debugging format needs mangled names.
1733 * debug-dwarf2.c: Improved support for classes, added member functions.
1735 2002-03-16 Martin Baulig <martin@gnome.org>
1737 * debug.c (mono_debug_get_type): Recursively call this for all members and
1738 parent classes of a class type.
1740 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1741 since GDB doesn't like Java very much.
1743 2002-03-16 Martin Baulig <martin@gnome.org>
1745 * debug-dwarf2.c: Added support for enums.
1747 2002-03-15 Martin Baulig <martin@gnome.org>

1768 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1770 (mono_debug_open_file): Added MonoDebugFormat argument.
1771 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1772 this function from GDB. It's now safe to call this function multiple times;
1773 it'll always write a complete debugging file.
1775 * debug.c: Splitted this file into a general part which remains in this file
1776 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1777 All public functions now call a corresponding format specific function.
1779 * debug.c: The following changes are private to debug.c:
1780 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1781 (record_line_number, debug_generate_method_lines): New private functions.
1782 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1783 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1784 mono_debug_open_assembly_dwarf2).
1785 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1786 now safe to call this function multiple times.
1787 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1788 returns an unique index for this type. It's used to ensure that we only write
1789 each class once to the debugging file.
1790 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1791 data structure, but don't directly write to the debugging file. This is done
1792 later from mono_debug_write_assembly().
1794 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1795 debugging output. Call mono_debug_close() on cleanup if necessary.
1797 2002-03-14 Martin Baulig <martin@gnome.org>
1799 * debug-private.h: New private header file.
1801 * debug-stabs.c: Added the stabs type generation stuff which was
1802 previously in debug.c.
1804 * debug-dwarf.c: Started to implement type support. We're currently
1805 only writing this most basic types to the dwarf file, but this will
1808 2002-03-13 Martin Baulig <martin@gnome.org>
1810 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1811 debugging code. They're now in CVS, but not yet used anywhere.
1813 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1815 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1816 macros, included new delegate code from Daniel Stodden.

1821 * jit.c: verify that corlib and runtime are in sync.
1823 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1825 * emit-x86.c, jit.c: use the debug-helpers facilities to
1826 describe and match a method when debugging.
1828 2002-03-10 Martin Baulig <martin@gnome.org>
1830 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1831 output, put a nop instruction at the start of all functions so that
1832 the adresses won't change when using --debug.
1834 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1835 the bytecode area, stabs needs a line number in the .il file. Use the
1836 new info->moffsets to get the line number.
1837 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1838 `moffsets' is an array of `total_lines' fields (total number of lines
1839 in the .il file); for each line in the .il field, this array contains
1840 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1841 of a method and 0 otherwise.
1842 (debug_load_method_lines): Read the whole .il file and initialize the
1843 info->moffsets field.
1845 2002-03-09 Martin Baulig <martin@gnome.org>
1847 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1848 the unnecessary CDQ instruction.
1850 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
