1 2003-01-26 Martin Baulig <martin@ximian.com>
3 * debug.c (mono_debug_init): Take a boolean argument which
4 specifies whether we're running in the Mono Debugger.
6 2003-01-24 Martin Baulig <martin@ximian.com>
8 * debug.c (mono_debug_io_layer): Disable this on Windows.
10 2003-01-23 Dick Porter <dick@ximian.com>
12 * mono.c: Use mono_runtime_exec_managed_code() to run all managed
15 * jit.c: Changed thread start and attach callbacks to pass the
16 thread ID, not the MonoThread pointer. Arrange that managed code
17 execution will fail an assertion in the main thread, just to be
20 2003-01-22 Martin Baulig <martin@ximian.com>
22 * debug.c: Reverted Gonzalo's last change since it is wrong.
23 We're also using the debugging code on Windows, for instance the
24 stabs stuff when running in gdb. I hope this code still builds on
25 Windows; if not, we need to fix this.
26 Moved all the mono debugger support code into the debugger itself;
27 when debugging a managed application, the debugger new launches a
28 small unmanaged wrapper application which contains this stuff.
30 * debug.h (MonoDebuggerIOLayer): New public typedef; this is just
31 initialized to an array of function pointers to the io-layer
32 function; they don't seem to be public in the `libmono' library.
33 (mono_debugger_event): New public function. Sends the debugger an
34 event if we're running in the Mono Debugger and does nothing otherwise.
36 * mono.c: Don't initialize the Mono Debugger here.
38 * jit.c (mono_debug_insert_breakpoint): Removed, this isn't used anymore.
39 (mono_thread_start_cb, mono_thread_attach_cb): Call
40 mono_debugger_event() to send the debugger a callback.
42 2003-01-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
44 * debug.c: make all public symbols just dummy for windows.
46 2003-01-20 Miguel de Icaza <miguel@ximian.com>
48 * debug.c (initialize_debugger_support): ifdef out the call to
49 mono_debugger_init_thread_debug for the release.
51 Someone should look into why its not defined. I think the problem
52 is what Dick pointed out somewhere: code in io-layer is not
53 supposed to ever be used in Windows, so code for the debugger that
54 lives there must be moved elsewhere.
56 2003-01-19 Martin Baulig <martin@ximian.com>
58 * debug.c: Ok, this should now finally be working this time ....
60 2003-01-18 Martin Baulig <martin@ximian.com>
62 * debug.c (mono_debugger_jit_exec): Send the background thread a
63 SIGKILL before returning.
65 2003-01-17 Dietmar Maurer <dietmar@ximian.com>
67 * x86.brg: removed duplicated CONV_OVF_I4
69 2003-01-17 Martin Baulig <martin@ximian.com>
71 * debug.c: Don't use mono_once here. Reworked the API a bit to
72 use `mono_debug_' and `debug_' for the general debugging API and
73 `mono_debugger_' and `debugger_' for the Mono Debugger stuff.
75 2003-01-16 Martin Baulig <martin@ximian.com>
77 * debug.c (debugger_thread_func): We don't need to `raise
78 (SIGSTOP)' anymore; the thread manager already takes care of this.
80 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
82 * exception.c (arch_handle_exception): exclude runtime invoke
83 wrapper from the stack trace
85 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
86 (mono_thread_start_cb): save an additional LMF at thread start
88 2003-01-16 Martin Baulig <martin@ximian.com>
90 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
91 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
92 and the LinuxThreads port doesn't allow you to override the handler.
93 [FIXME: This avoids an assertion failure on startup, but there's
94 still an issue with thread termination.]
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 Martin Baulig <martin@ximian.com>
103 * debug.c: Use the mono/io-layer functions here instead of gthread.
105 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
107 * jit.c (mono_jit_compile_method): make sure runtime_init is called
108 (mono_analyze_stack): make sure runtime_init is called
110 2003-01-14 Martin Baulig <martin@ximian.com>
112 * debug.c (debugger_update_symbol_file_table): Moved all the
113 functionality into debugger_update_symbol_file_table_internal();
114 the latter one will be called from the background thread while
115 already owning the lock. This'll allow us to step into
116 debugger_update_symbol_file_table() in the debugger and debug it.
118 2003-01-14 Martin Baulig <martin@ximian.com>
120 * Makefile.am: Link against gthread.
122 * jit.c: After realizing that mono-mutex doesn't work either
123 because it doesn't support recursive mutexes on FreeBSD, rewrote
124 the whole thread stuff to use gthread. This seems to fix this
125 weird deadlock in the debugger as well.
127 2003-01-12 Alp Toker <alp@atoker.com>
129 * exception.c: Typo fix: insinde -> inside
131 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
133 * exception.c (ves_icall_get_frame_info): skip one more frame and also
134 MONO_WRAPPER_RUNTIME_INVOKE wrappers
135 (x86_unwind_native_frame): disable unnecessary assertion
137 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
139 * exception.c (ves_icall_get_frame_info): fix bug 36382
141 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
143 * jit.c: handle wrapper_data in NEWOBJ/CALL.
145 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
147 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
149 2003-01-06 Martin Baulig <martin@ximian.com>
151 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
153 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
154 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
156 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
158 * debug.c: Move must_send_finished var declaration out of #if win32
159 block (this fixes the build on win32)
161 2003-01-05 Martin Baulig <martin@ximian.com>
163 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
164 this is used when we're running inside the Mono Debugger
165 (mono_debugger_wait): Put the waiting code into a function of its own.
167 * mono.c (main): Call mono_debugger_jit_exec() instead of
168 mono_jit_exec() if we're running inside the Mono Debugger.
170 2003-01-05 Martin Baulig <martin@ximian.com>
172 * debug.h (MonoDebugFormat): Added
173 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
174 we're running inside the Mono Debugger prior to the args parsing.
176 2003-01-04 Martin Baulig <martin@ximian.com>
178 * debug.c (release_symbol_file_table): Only call this if we're
179 actually modifying the symbol tables.
180 (mono_debug_open): Always set the `mono_debugger_class_init_func'
181 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
183 2003-01-03 Martin Baulig <martin@ximian.com>
185 * debug.c: Disable the mono debugger stuff on Windows.
187 2003-01-03 Martin Baulig <martin@ximian.com>
189 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
190 function. This is called from the breakpoint trampoline to signal
191 the debugger and wait until it has reload the symbol tables.
193 * trampoline.c (get_breakpoint_trampoline): Call the new
194 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
195 trampoline just before the breakpoint.
197 2002-12-31 Martin Baulig <martin@ximian.com>
199 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
200 field to point to the MonoGlobalSymbolTable.
202 2002-12-30 Martin Baulig <martin@ximian.com>
204 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
205 This variable now specifies that the symbol tables have been
206 modified after the last notification has been send. The debugger
207 uses this flag to check whether it needs to reload the symbol
209 (debugger_compile_method): Just send a notification to the
210 debugger, but don't set the modified flag. It may or may not be
211 set when the debugger gets the notification - depending on whether
212 the JIT compilation added a new method to the symbol tables.
214 2002-12-30 Martin Baulig <martin@ximian.com>
216 * debug.c (debugger_compile_method): This is a wrapper around
217 mono_compile_method() which always sends a notification to the
220 2002-12-30 Martin Baulig <martin@ximian.com>
222 * debug.c: Reload the symbol file table before sending the
223 notification event to the debugger.
224 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
226 2002-12-31 Martin Baulig <martin@ximian.com>
228 * debug.c: Propertly lock everything and avoid race conditions.
229 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
231 2002-12-31 Duncan Mak <duncan@ximian.com>
233 * debug.c (initialize_debugger_support): Fix build error by
234 declaring ret at the top of the function.
236 2002-12-30 Martin Baulig <martin@ximian.com>
238 * debug.c: When running under the mono debugger, create a special
239 debugger thread; always protect the symbol tables with a mutex.
241 2002-12-28 Martin Baulig <martin@ximian.com>
243 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
244 incremented each time one of the symbol tables is modified.
246 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
248 * jit.c: fix LDELEMA implementation here as well.
250 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
252 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
254 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
256 * jit.c: query the thread abort signal from the runtime.
258 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
260 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
262 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
264 * jit.c (mono_analyze_stack): call the utility function
265 mono_field_from_token to avoid code duplication.
267 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
269 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
271 * x86.brg (stmt): POP floating point stack correctly
273 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
275 * emit-x86.c (arch_emit_prologue): don't save caller saved
278 * exception.c (x86_unwind_native_frame): support exceptions inside
279 native code using gcc generated exception tables (-fexception).
281 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
283 * exception.c: include some code from Zoltan Varga, but modified
286 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
288 * exception.c: massive code cleanups. The code is still
289 architecture dependent, but it should be now possible to reuse the
290 complex parts for other architecture.
292 2002-11-15 Dick Porter <dick@ximian.com>
294 * jit.c: Pass the attach callback to mono_runtime_init().
296 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
298 * jit.c: display the domain name in trace output.
300 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
302 * x86.brg (reg): fix bug #2721
304 * jit.c (mono_runtime_install_handlers): impl.
306 2002-10-17 Martin Baulig <martin@gnome.org>
308 * debug.c (mono_debug_add_method): Make this actually work if we don't
309 have any lifetime information.
311 2002-10-15 Martin Baulig <martin@gnome.org>
313 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
315 * debug.c (generate_line_number): Small fix to make this actually
316 work for more complex things.
318 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
320 * x86.brg (freg): use fprem instead of fprem1
322 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
324 * jit.c (ves_array_element_address): added check for out of range index
325 (mono_analyze_stack): added fix for bug #31654
327 2002-10-01 Martin Baulig <martin@gnome.org>
329 * debug.c: Don't create an .il file for the dynamic symbol file.
331 2002-10-01 Martin Baulig <martin@gnome.org>
333 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
335 2002-09-27 Martin Baulig <martin@gnome.org>
337 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
339 2002-09-27 Dick Porter <dick@ximian.com>
341 * mono.c: Tell glib what the program name is, by passing it the
342 name of the managed file we're executing
344 2002-09-26 Martin Baulig <martin@gnome.org>
346 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
347 trampoline into the vtable, also use it for non-virtual methods,
348 remove the breakpoint when done.
350 2002-09-26 Martin Baulig <martin@gnome.org>
352 * debug.c (debug_load_method_lines): Block SIGCHLD while running
355 2002-09-26 Martin Baulig <martin@gnome.org>
357 * debug.c: Reworked the whole debugging stuff. We have now one
358 single `mono_debug_handle' which keeps a hashtable of
359 `AssemblyDebugInfo's (which may have different debugging formats).
360 The AssemblyDebugInfo is now created when the assembly is loaded,
361 but never when adding a class/type.
363 * mono.c: Initialize debugging stuff after corlib and the assembly
366 2002-09-25 Martin Baulig <martin@gnome.org>
368 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
369 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
371 (DebugMethodInfo): Removed `line_numbers'.
373 * debug.c: Reworked the line number generation; we're now using
374 the MonoDebugLineNumberEntry try for all debugging formats. This
375 type also includes the line number and IL offset, this allows the
376 JIT to produce better line number info: we only emit line number
377 information for source lines which actually have code.
379 2002-09-25 Martin Baulig <martin@gnome.org>
381 * debug.h: Removed external declaration of all functions which
382 should only be called from the Mono Debugger and also made them
383 static. Since the debugger gets their address from the
384 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
387 2002-09-25 Martin Baulig <martin@gnome.org>
389 Improved breakpoint support, we can now dynamically insert and
390 remove breakpoints at runtime and when called from withing the
391 Mono Debugger, we're using a special breakpoint trampoline.
393 * debug.h (mono_method_has_breakpoint): New method to check
394 whether to insert a breakpoint for a method.
395 (mono_insert_breakpoint): New method to insert a breakpoint.
396 (mono_insert_breakpoint_full): New method to insert a breakpoint,
397 takes a MonoMethodDesc.
398 (mono_remove_breakpoint): New method to remove a breakpoint.
400 * debug.c (mono_debugger_insert_breakpoint): New function for the
401 debugger. Should only be called from the debugger.
402 (mono_debugger_remove_breakpoint): Likewise.
404 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
406 * trampoline.c (get_breakpoint_trampoline): New static function to
407 create a special breakpoint trampoline for the debugger.
408 (x86_magic_trampoline): If we're running inside the Mono Debugger
409 and a breakpoint was requested for the method, generate a special
410 breakpoint trampoline.
412 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
413 to insert a breakpoint.
414 (mono_debug_last_breakpoint_address): Removed.
415 (match_debug_method): Removed, use mono_method_has_breakpoint().
417 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
419 * jit.c: reorder mono_runtime_cleanup () call since it needs the
420 engine still fully working.
422 2002-09-24 Martin Baulig <martin@gnome.org>
424 * debug.c (mono_debug_open): When we're invoked from inside the
425 Mono Debugger, set mono_debugger_class_init_func (exported in
426 metadata/class.c) to mono_add_type().
427 (mono_add_type): Call mono_debug_symfile_add_type().
429 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
431 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
432 Run finalize on domain cleanup.
433 * mono.c: call setlocale ().
434 * trampoline.c: clearer error message for invalid trampoline.
436 2002-09-21 Martin Baulig <martin@gnome.org>
438 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
439 instead of writing a byte blob.
440 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
441 (mono_debug_add_method): Incrementally add the new method to the symbol
444 * exception.c (arch_handle_exception): If we have debugging support,
445 call mono_debugger_update_symbol_file_table () as well.
447 2002-09-20 Martin Baulig <martin@gnome.org>
449 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
450 the size of the variable.
452 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
454 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
455 iterations if we visit blocks in reverse order.
457 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
459 * jit.c (mono_analyze_stack): cleaup of the array code
461 * exception.c: added patch from Julio Merno to fix bug #30048
463 * jit.c (mono_analyze_stack): code cleanup, fix bug #29365
465 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
467 * x86.brg (LDELEMA): use x86_lea
469 2002-09-06 Martin Baulig <martin@gnome.org>
471 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
472 If you were getting random crashes when using the JIT with debugging
473 turned on, this fixes it.
475 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
477 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
479 2002-09-05 Martin Baulig <martin@gnome.org>
481 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
482 which is read by the debugger.
484 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>
486 * Makefile.am: link libmono directly into mono. Use a ld script
487 to reduce exported symbols.
489 2002-09-03 Martin Baulig <martin@gnome.org>
491 * debug.c (free_method_info): Make this actually work.
493 2002-09-03 Martin Baulig <martin@gnome.org>
495 * debug.h (MonoDebugFormat): Killed MONO_DEBUG_FORMAT_DWARF2_PLUS.
496 * debug-dwarf2-plus.c: Removed.
498 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
499 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
500 `mono_symfile' to `symfile'.
502 * debug.c (mono_debug_open): Replaced the assembly argument with a
503 file name argument; you can now call this before loading the assembly.
504 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
505 we now use MonoSymbolFileLineNumberEntry's and a separate address array
506 instead; splitted out all MonoSymbolFileLineNumberEntry code into
507 debug_generate_il_offsets() and debug_update_il_offsets().
508 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
509 created when reading the symbol file or from debug_load_method_lines().
510 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
512 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before
513 looking up an address.
515 * debug.c: Don't create the .il files for MONO_DEBUG_FORMAT_MONO.
517 * mono.c (main): Initialize debugging before loading the first assembly.
519 2002-08-28 Dick Porter <dick@ximian.com>
521 * mono.c: mono_set_rootdir() doesnt take any args now
523 * Makefile.am: Export HOST_CC for w32 builds
525 2002-08-28 Dietmar Maurer <dietmar@ximian.com>
527 * jit.c (mono_store_tree): only allocate vars if really necessary
529 2002-08-27 Martin Baulig <martin@gnome.org>
531 * debug.c: The mono symbol file is installed together with the assembly
532 it belongs to and it's used on a per-image basis.
534 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
536 * mono.c: don't use the cil-coff header outside of the loader.
538 2002-08-27 Martin Baulig <martin@gnome.org>
540 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
541 to use global variables for this since they're stored in a core file.
542 (mono_debugger_symbol_file_table_generation): New global variable.
543 (mono_debugger_symbol_file_table): New global variable.
544 (mono_debugger_update_symbol_file_table): New global function to update
545 the symbol file table.
547 2002-08-27 Martin Baulig <martin@gnome.org>
549 * trampoline.c (mono_generic_trampoline_code): New global variable.
550 (arch_create_jit_trampoline): Use the new global variable to store the
551 generic trampoline code instead of using a static one. This allows the
552 debugger to access this variable to check whether a method is a trampoline.
554 * debug.h (mono_generic_trampoline_code): Added external declaration.
556 2002-08-27 Martin Baulig <martin@gnome.org>
558 * debug.c (MonoDebugHandle): Moved the method hash into the
559 AssemblyDebugInfo struct since we need to use a separate hash for each
562 * debug.c: Added special undocumented command line argument to create a
563 symbol file for IL files on-the-fly. In this case, we also need to create
564 the IL files and parse them.
565 (mono_debugger_internal_get_symbol_files): Return something more reasonable.
567 2002-08-26 Martin Baulig <martin@gnome.org>
569 * debug.c (mono_debugger_internal_free_symbol_files): New function.
570 (mono_debugger_internal_symbol_files_changed): New global variable.
572 2002-08-24 Martin Baulig <martin@gnome.org>
574 * debug.c (mono_debugger_internal_get_symbol_files): New function.
576 2002-08-24 Martin Baulig <martin@gnome.org>

1730 since GDB doesn't like Java very much.
1732 2002-03-16 Martin Baulig <martin@gnome.org>
1734 * debug-dwarf2.c: Added support for enums.
1736 2002-03-15 Martin Baulig <martin@gnome.org>

1757 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1759 (mono_debug_open_file): Added MonoDebugFormat argument.
1760 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1761 this function from GDB. It's now safe to call this function multiple times;
1762 it'll always write a complete debugging file.
1764 * debug.c: Splitted this file into a general part which remains in this file
1765 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1766 All public functions now call a corresponding format specific function.
1768 * debug.c: The following changes are private to debug.c:
1769 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1770 (record_line_number, debug_generate_method_lines): New private functions.
1771 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1772 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1773 mono_debug_open_assembly_dwarf2).
1774 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1775 now safe to call this function multiple times.
1776 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1777 returns an unique index for this type. It's used to ensure that we only write
1778 each class once to the debugging file.
1779 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1780 data structure, but don't directly write to the debugging file. This is done
1781 later from mono_debug_write_assembly().
1783 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1784 debugging output. Call mono_debug_close() on cleanup if necessary.
1786 2002-03-14 Martin Baulig <martin@gnome.org>
1788 * debug-private.h: New private header file.
1790 * debug-stabs.c: Added the stabs type generation stuff which was
1791 previously in debug.c.
1793 * debug-dwarf.c: Started to implement type support. We're currently
1794 only writing this most basic types to the dwarf file, but this will
1797 2002-03-13 Martin Baulig <martin@gnome.org>
1799 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1800 debugging code. They're now in CVS, but not yet used anywhere.

1812 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1814 * emit-x86.c, jit.c: use the debug-helpers facilities to
1815 describe and match a method when debugging.
1817 2002-03-10 Martin Baulig <martin@gnome.org>
1819 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1820 output, put a nop instruction at the start of all functions so that
1821 the adresses won't change when using --debug.
1823 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1824 the bytecode area, stabs needs a line number in the .il file. Use the
1825 new info->moffsets to get the line number.
1826 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1827 `moffsets' is an array of `total_lines' fields (total number of lines
1828 in the .il file); for each line in the .il field, this array contains
1829 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1830 of a method and 0 otherwise.
1831 (debug_load_method_lines): Read the whole .il file and initialize the
1832 info->moffsets field.
1834 2002-03-09 Martin Baulig <martin@gnome.org>
1836 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1837 the unnecessary CDQ instruction.
