1 2003-01-29 Dietmar Maurer <dietmar@ximian.com>
3 * jit.c (mono_analyze_stack): impl. CEE_MONO_LDNATIVEOBJ
4 (mono_analyze_stack): RETOBJ always returns native sized objects
6 2003-01-28 Zoltan Varga <vargaz@freemail.hu>
8 * x86.brg (mono_ldintftn): use <= instead of <, since the
9 interface_offsets array is max_interface_id + 1 long.
11 2003-01-28 Dietmar Maurer <dietmar@ximian.com>
13 * x86.brg (mono_ldintftn): fix from Zoltan: use max_interface_id
15 2003-01-27 Zoltan Varga <vargaz@freemail.hu>
17 * exception.c (ves_icall_get_trace): avoid crash if the exception is
20 * exception.c (ves_icall_get_trace): avoid crash on unmanaged frames.
22 2003-01-26 Martin Baulig <martin@ximian.com>
24 * debug.c (mono_debug_init): Take a boolean argument which
25 specifies whether we're running in the Mono Debugger.
27 2003-01-24 Martin Baulig <martin@ximian.com>
29 * debug.c (mono_debug_io_layer): Disable this on Windows.
31 2003-01-23 Dick Porter <dick@ximian.com>
33 * mono.c: Use mono_runtime_exec_managed_code() to run all managed
36 * jit.c: Changed thread start and attach callbacks to pass the
37 thread ID, not the MonoThread pointer. Arrange that managed code
38 execution will fail an assertion in the main thread, just to be
41 2003-01-22 Martin Baulig <martin@ximian.com>
43 * debug.c: Reverted Gonzalo's last change since it is wrong.
44 We're also using the debugging code on Windows, for instance the
45 stabs stuff when running in gdb. I hope this code still builds on
46 Windows; if not, we need to fix this.
47 Moved all the mono debugger support code into the debugger itself;
48 when debugging a managed application, the debugger new launches a
49 small unmanaged wrapper application which contains this stuff.
51 * debug.h (MonoDebuggerIOLayer): New public typedef; this is just
52 initialized to an array of function pointers to the io-layer
53 function; they don't seem to be public in the `libmono' library.
54 (mono_debugger_event): New public function. Sends the debugger an
55 event if we're running in the Mono Debugger and does nothing otherwise.
57 * mono.c: Don't initialize the Mono Debugger here.
59 * jit.c (mono_debug_insert_breakpoint): Removed, this isn't used anymore.
60 (mono_thread_start_cb, mono_thread_attach_cb): Call
61 mono_debugger_event() to send the debugger a callback.
63 2003-01-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
65 * debug.c: make all public symbols just dummy for windows.
67 2003-01-20 Miguel de Icaza <miguel@ximian.com>
69 * debug.c (initialize_debugger_support): ifdef out the call to
70 mono_debugger_init_thread_debug for the release.
72 Someone should look into why its not defined. I think the problem
73 is what Dick pointed out somewhere: code in io-layer is not
74 supposed to ever be used in Windows, so code for the debugger that
75 lives there must be moved elsewhere.
77 2003-01-19 Martin Baulig <martin@ximian.com>
79 * debug.c: Ok, this should now finally be working this time ....
81 2003-01-18 Martin Baulig <martin@ximian.com>
83 * debug.c (mono_debugger_jit_exec): Send the background thread a
84 SIGKILL before returning.
86 2003-01-17 Dietmar Maurer <dietmar@ximian.com>
88 * x86.brg: removed duplicated CONV_OVF_I4
90 2003-01-17 Martin Baulig <martin@ximian.com>
92 * debug.c: Don't use mono_once here. Reworked the API a bit to
93 use `mono_debug_' and `debug_' for the general debugging API and
94 `mono_debugger_' and `debugger_' for the Mono Debugger stuff.
96 2003-01-16 Martin Baulig <martin@ximian.com>
98 * debug.c (debugger_thread_func): We don't need to `raise
99 (SIGSTOP)' anymore; the thread manager already takes care of this.
101 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
103 * exception.c (arch_handle_exception): exclude runtime invoke
104 wrapper from the stack trace
106 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
107 (mono_thread_start_cb): save an additional LMF at thread start
109 2003-01-16 Martin Baulig <martin@ximian.com>
111 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
112 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
113 and the LinuxThreads port doesn't allow you to override the handler.
114 [FIXME: This avoids an assertion failure on startup, but there's
115 still an issue with thread termination.]
117 2003-01-16 Martin Baulig <martin@ximian.com>
119 * debug.c (debugger_thread_func): We don't need to `raise
120 (SIGSTOP)' anymore; the thread manager already takes care of this.
122 2003-01-16 Martin Baulig <martin@ximian.com>
124 * debug.c: Use the mono/io-layer functions here instead of gthread.
126 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
128 * jit.c (mono_jit_compile_method): make sure runtime_init is called
129 (mono_analyze_stack): make sure runtime_init is called
131 2003-01-14 Martin Baulig <martin@ximian.com>
133 * debug.c (debugger_update_symbol_file_table): Moved all the
134 functionality into debugger_update_symbol_file_table_internal();
135 the latter one will be called from the background thread while
136 already owning the lock. This'll allow us to step into
137 debugger_update_symbol_file_table() in the debugger and debug it.
139 2003-01-14 Martin Baulig <martin@ximian.com>
141 * Makefile.am: Link against gthread.
143 * jit.c: After realizing that mono-mutex doesn't work either
144 because it doesn't support recursive mutexes on FreeBSD, rewrote
145 the whole thread stuff to use gthread. This seems to fix this
146 weird deadlock in the debugger as well.
148 2003-01-12 Alp Toker <alp@atoker.com>
150 * exception.c: Typo fix: insinde -> inside
152 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
154 * exception.c (ves_icall_get_frame_info): skip one more frame and also
155 MONO_WRAPPER_RUNTIME_INVOKE wrappers
156 (x86_unwind_native_frame): disable unnecessary assertion
158 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
160 * exception.c (ves_icall_get_frame_info): fix bug 36382
162 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
164 * jit.c: handle wrapper_data in NEWOBJ/CALL.
166 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
168 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
170 2003-01-06 Martin Baulig <martin@ximian.com>
172 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
174 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
175 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
177 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
179 * debug.c: Move must_send_finished var declaration out of #if win32
180 block (this fixes the build on win32)
182 2003-01-05 Martin Baulig <martin@ximian.com>
184 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
185 this is used when we're running inside the Mono Debugger
186 (mono_debugger_wait): Put the waiting code into a function of its own.
188 * mono.c (main): Call mono_debugger_jit_exec() instead of
189 mono_jit_exec() if we're running inside the Mono Debugger.
191 2003-01-05 Martin Baulig <martin@ximian.com>
193 * debug.h (MonoDebugFormat): Added
194 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
195 we're running inside the Mono Debugger prior to the args parsing.
197 2003-01-04 Martin Baulig <martin@ximian.com>
199 * debug.c (release_symbol_file_table): Only call this if we're
200 actually modifying the symbol tables.
201 (mono_debug_open): Always set the `mono_debugger_class_init_func'
202 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
204 2003-01-03 Martin Baulig <martin@ximian.com>
206 * debug.c: Disable the mono debugger stuff on Windows.
208 2003-01-03 Martin Baulig <martin@ximian.com>
210 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
211 function. This is called from the breakpoint trampoline to signal
212 the debugger and wait until it has reload the symbol tables.
214 * trampoline.c (get_breakpoint_trampoline): Call the new
215 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
216 trampoline just before the breakpoint.
218 2002-12-31 Martin Baulig <martin@ximian.com>
220 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
221 field to point to the MonoGlobalSymbolTable.
223 2002-12-30 Martin Baulig <martin@ximian.com>
225 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
226 This variable now specifies that the symbol tables have been
227 modified after the last notification has been send. The debugger
228 uses this flag to check whether it needs to reload the symbol
230 (debugger_compile_method): Just send a notification to the
231 debugger, but don't set the modified flag. It may or may not be
232 set when the debugger gets the notification - depending on whether
233 the JIT compilation added a new method to the symbol tables.
235 2002-12-30 Martin Baulig <martin@ximian.com>
237 * debug.c (debugger_compile_method): This is a wrapper around
238 mono_compile_method() which always sends a notification to the
241 2002-12-30 Martin Baulig <martin@ximian.com>
243 * debug.c: Reload the symbol file table before sending the
244 notification event to the debugger.
245 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
247 2002-12-31 Martin Baulig <martin@ximian.com>
249 * debug.c: Propertly lock everything and avoid race conditions.
250 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
252 2002-12-31 Duncan Mak <duncan@ximian.com>
254 * debug.c (initialize_debugger_support): Fix build error by
255 declaring ret at the top of the function.
257 2002-12-30 Martin Baulig <martin@ximian.com>
259 * debug.c: When running under the mono debugger, create a special
260 debugger thread; always protect the symbol tables with a mutex.
262 2002-12-28 Martin Baulig <martin@ximian.com>
264 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
265 incremented each time one of the symbol tables is modified.
267 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
269 * jit.c: fix LDELEMA implementation here as well.
271 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
273 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
275 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
277 * jit.c: query the thread abort signal from the runtime.
279 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
281 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
283 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
285 * jit.c (mono_analyze_stack): call the utility function
286 mono_field_from_token to avoid code duplication.
288 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
290 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
292 * x86.brg (stmt): POP floating point stack correctly
294 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
296 * emit-x86.c (arch_emit_prologue): don't save caller saved
299 * exception.c (x86_unwind_native_frame): support exceptions inside
300 native code using gcc generated exception tables (-fexception).
302 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
304 * exception.c: include some code from Zoltan Varga, but modified
307 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
309 * exception.c: massive code cleanups. The code is still
310 architecture dependent, but it should be now possible to reuse the
311 complex parts for other architecture.
313 2002-11-15 Dick Porter <dick@ximian.com>
315 * jit.c: Pass the attach callback to mono_runtime_init().
317 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
319 * jit.c: display the domain name in trace output.
321 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
323 * x86.brg (reg): fix bug #2721
325 * jit.c (mono_runtime_install_handlers): impl.
327 2002-10-17 Martin Baulig <martin@gnome.org>
329 * debug.c (mono_debug_add_method): Make this actually work if we don't
330 have any lifetime information.
332 2002-10-15 Martin Baulig <martin@gnome.org>
334 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
336 * debug.c (generate_line_number): Small fix to make this actually
337 work for more complex things.
339 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
341 * x86.brg (freg): use fprem instead of fprem1
343 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
345 * jit.c (ves_array_element_address): added check for out of range index
346 (mono_analyze_stack): added fix for bug #31654
348 2002-10-01 Martin Baulig <martin@gnome.org>
350 * debug.c: Don't create an .il file for the dynamic symbol file.
352 2002-10-01 Martin Baulig <martin@gnome.org>
354 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
356 2002-09-27 Martin Baulig <martin@gnome.org>
358 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
360 2002-09-27 Dick Porter <dick@ximian.com>
362 * mono.c: Tell glib what the program name is, by passing it the
363 name of the managed file we're executing
365 2002-09-26 Martin Baulig <martin@gnome.org>
367 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
368 trampoline into the vtable, also use it for non-virtual methods,
369 remove the breakpoint when done.
371 2002-09-26 Martin Baulig <martin@gnome.org>
373 * debug.c (debug_load_method_lines): Block SIGCHLD while running
376 2002-09-26 Martin Baulig <martin@gnome.org>
378 * debug.c: Reworked the whole debugging stuff. We have now one
379 single `mono_debug_handle' which keeps a hashtable of
380 `AssemblyDebugInfo's (which may have different debugging formats).
381 The AssemblyDebugInfo is now created when the assembly is loaded,
382 but never when adding a class/type.
384 * mono.c: Initialize debugging stuff after corlib and the assembly
387 2002-09-25 Martin Baulig <martin@gnome.org>
389 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
390 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
392 (DebugMethodInfo): Removed `line_numbers'.
394 * debug.c: Reworked the line number generation; we're now using
395 the MonoDebugLineNumberEntry try for all debugging formats. This
396 type also includes the line number and IL offset, this allows the
397 JIT to produce better line number info: we only emit line number
398 information for source lines which actually have code.
400 2002-09-25 Martin Baulig <martin@gnome.org>
402 * debug.h: Removed external declaration of all functions which
403 should only be called from the Mono Debugger and also made them
404 static. Since the debugger gets their address from the
405 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
408 2002-09-25 Martin Baulig <martin@gnome.org>
410 Improved breakpoint support, we can now dynamically insert and
411 remove breakpoints at runtime and when called from withing the
412 Mono Debugger, we're using a special breakpoint trampoline.
414 * debug.h (mono_method_has_breakpoint): New method to check
415 whether to insert a breakpoint for a method.
416 (mono_insert_breakpoint): New method to insert a breakpoint.
417 (mono_insert_breakpoint_full): New method to insert a breakpoint,
418 takes a MonoMethodDesc.
419 (mono_remove_breakpoint): New method to remove a breakpoint.
421 * debug.c (mono_debugger_insert_breakpoint): New function for the
422 debugger. Should only be called from the debugger.
423 (mono_debugger_remove_breakpoint): Likewise.
425 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
427 * trampoline.c (get_breakpoint_trampoline): New static function to
428 create a special breakpoint trampoline for the debugger.
429 (x86_magic_trampoline): If we're running inside the Mono Debugger
430 and a breakpoint was requested for the method, generate a special
431 breakpoint trampoline.
433 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
434 to insert a breakpoint.
435 (mono_debug_last_breakpoint_address): Removed.
436 (match_debug_method): Removed, use mono_method_has_breakpoint().
438 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
440 * jit.c: reorder mono_runtime_cleanup () call since it needs the
441 engine still fully working.
443 2002-09-24 Martin Baulig <martin@gnome.org>
445 * debug.c (mono_debug_open): When we're invoked from inside the
446 Mono Debugger, set mono_debugger_class_init_func (exported in
447 metadata/class.c) to mono_add_type().
448 (mono_add_type): Call mono_debug_symfile_add_type().
450 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
452 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
453 Run finalize on domain cleanup.
454 * mono.c: call setlocale ().
455 * trampoline.c: clearer error message for invalid trampoline.
457 2002-09-21 Martin Baulig <martin@gnome.org>
459 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
460 instead of writing a byte blob.
461 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
462 (mono_debug_add_method): Incrementally add the new method to the symbol
465 * exception.c (arch_handle_exception): If we have debugging support,
466 call mono_debugger_update_symbol_file_table () as well.
468 2002-09-20 Martin Baulig <martin@gnome.org>
470 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
471 the size of the variable.
473 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
475 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
476 iterations if we visit blocks in reverse order.
478 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
480 * jit.c (mono_analyze_stack): cleaup of the array code
482 * exception.c: added patch from Julio Merno to fix bug #30048
484 * jit.c (mono_analyze_stack): code cleanup, fix bug #29365
486 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
488 * x86.brg (LDELEMA): use x86_lea
490 2002-09-06 Martin Baulig <martin@gnome.org>
492 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
493 If you were getting random crashes when using the JIT with debugging
494 turned on, this fixes it.
496 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
498 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
500 2002-09-05 Martin Baulig <martin@gnome.org>
502 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
503 which is read by the debugger.
505 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>
507 * Makefile.am: link libmono directly into mono. Use a ld script
508 to reduce exported symbols.
510 2002-09-03 Martin Baulig <martin@gnome.org>
512 * debug.c (free_method_info): Make this actually work.
514 2002-09-03 Martin Baulig <martin@gnome.org>
516 * debug.h (MonoDebugFormat): Killed MONO_DEBUG_FORMAT_DWARF2_PLUS.
517 * debug-dwarf2-plus.c: Removed.
519 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
520 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
521 `mono_symfile' to `symfile'.
523 * debug.c (mono_debug_open): Replaced the assembly argument with a
524 file name argument; you can now call this before loading the assembly.
525 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
526 we now use MonoSymbolFileLineNumberEntry's and a separate address array
527 instead; splitted out all MonoSymbolFileLineNumberEntry code into
528 debug_generate_il_offsets() and debug_update_il_offsets().
529 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
530 created when reading the symbol file or from debug_load_method_lines().
531 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
533 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before
534 looking up an address.
536 * debug.c: Don't create the .il files for MONO_DEBUG_FORMAT_MONO.
538 * mono.c (main): Initialize debugging before loading the first assembly.
540 2002-08-28 Dick Porter <dick@ximian.com>
542 * mono.c: mono_set_rootdir() doesnt take any args now
544 * Makefile.am: Export HOST_CC for w32 builds
546 2002-08-28 Dietmar Maurer <dietmar@ximian.com>
548 * jit.c (mono_store_tree): only allocate vars if really necessary
550 2002-08-27 Martin Baulig <martin@gnome.org>
552 * debug.c: The mono symbol file is installed together with the assembly
553 it belongs to and it's used on a per-image basis.
555 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
557 * mono.c: don't use the cil-coff header outside of the loader.
559 2002-08-27 Martin Baulig <martin@gnome.org>
561 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
562 to use global variables for this since they're stored in a core file.
563 (mono_debugger_symbol_file_table_generation): New global variable.
564 (mono_debugger_symbol_file_table): New global variable.
565 (mono_debugger_update_symbol_file_table): New global function to update
566 the symbol file table.
568 2002-08-27 Martin Baulig <martin@gnome.org>
570 * trampoline.c (mono_generic_trampoline_code): New global variable.
571 (arch_create_jit_trampoline): Use the new global variable to store the
572 generic trampoline code instead of using a static one. This allows the
573 debugger to access this variable to check whether a method is a trampoline.
575 * debug.h (mono_generic_trampoline_code): Added external declaration.

1110 file for all assemblies. Currently, the JIT doesn't put all methods
1111 from a single assembly into a continuous region of memory. We were
1112 previously creating valid DWARF 2 files for this, but unfortunately
1113 GDB's symbol tables get messed up when it reads more than one such file.
1115 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

1734 * debug-dwarf2.c: Added support for strings and arrays.
1736 2002-03-17 Martin Baulig <martin@gnome.org>
1738 * debug.c (mono_debug_get_type): Recursively call this for all function members
1740 (mono_debug_add_method): Don't mangle function names, this must be done by the
1741 debugger backend if the debugging format needs mangled names.
1743 * debug-dwarf2.c: Improved support for classes, added member functions.
1745 2002-03-16 Martin Baulig <martin@gnome.org>
1747 * debug.c (mono_debug_get_type): Recursively call this for all members and
1748 parent classes of a class type.
1750 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1751 since GDB doesn't like Java very much.
1753 2002-03-16 Martin Baulig <martin@gnome.org>
1755 * debug-dwarf2.c: Added support for enums.
1757 2002-03-15 Martin Baulig <martin@gnome.org>

1778 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1780 (mono_debug_open_file): Added MonoDebugFormat argument.
1781 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1782 this function from GDB. It's now safe to call this function multiple times;
1783 it'll always write a complete debugging file.
1785 * debug.c: Splitted this file into a general part which remains in this file
1786 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1787 All public functions now call a corresponding format specific function.
1789 * debug.c: The following changes are private to debug.c:
1790 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1791 (record_line_number, debug_generate_method_lines): New private functions.
1792 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1793 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1794 mono_debug_open_assembly_dwarf2).
1795 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1796 now safe to call this function multiple times.
1797 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1798 returns an unique index for this type. It's used to ensure that we only write
1799 each class once to the debugging file.
1800 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1801 data structure, but don't directly write to the debugging file. This is done
1802 later from mono_debug_write_assembly().
1804 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1805 debugging output. Call mono_debug_close() on cleanup if necessary.
1807 2002-03-14 Martin Baulig <martin@gnome.org>
1809 * debug-private.h: New private header file.
1811 * debug-stabs.c: Added the stabs type generation stuff which was
1812 previously in debug.c.
1814 * debug-dwarf.c: Started to implement type support. We're currently
1815 only writing this most basic types to the dwarf file, but this will
1818 2002-03-13 Martin Baulig <martin@gnome.org>
1820 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1821 debugging code. They're now in CVS, but not yet used anywhere.
1823 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1825 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*

1831 * jit.c: verify that corlib and runtime are in sync.
1833 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1835 * emit-x86.c, jit.c: use the debug-helpers facilities to
1836 describe and match a method when debugging.
1838 2002-03-10 Martin Baulig <martin@gnome.org>
1840 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1841 output, put a nop instruction at the start of all functions so that
1842 the adresses won't change when using --debug.
1844 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1845 the bytecode area, stabs needs a line number in the .il file. Use the
1846 new info->moffsets to get the line number.
1847 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1848 `moffsets' is an array of `total_lines' fields (total number of lines
1849 in the .il file); for each line in the .il field, this array contains
1850 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1851 of a method and 0 otherwise.
1852 (debug_load_method_lines): Read the whole .il file and initialize the
1853 info->moffsets field.
1855 2002-03-09 Martin Baulig <martin@gnome.org>
1857 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1858 the unnecessary CDQ instruction.
1860 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
