1 2003-04-23 Martin Baulig <martin@ximian.com>
3 * debug-jit.c (mono_debug_add_method): Renamed this to
4 mono_debug_jit_add_method(); create the JIT-specific data
5 structure and pass it to mono_debug_add_method().
7 * debug.[ch]: Removed. The code is now in
8 ../metadata/mono-debug.[ch] and mono-debug-debugger.[ch].
10 * debug-stabs.c, debug-dwarf2.c: Removed; nobody used this for the
13 2003-04-21 Martin Baulig <martin@ximian.com>
15 * debug.c (mono_debug_open): Splitted into mono_debug_init() and
17 (mono_debug_open_image): Don't open referenced assemblies; this is
18 done automatically by the code in assembly.c.
20 * mono.c (main_thread_handler): Call mono_debug_init() before
21 opening the assembly because we need to install the assembly load
24 2003-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
27 (mono_jit_cleanup): moved mono_runtime_cleanup call after the call to
30 2003-04-05 Miguel de Icaza <miguel@ximian.com>
32 * jit.c (check_inlining): honor the NOINLING atttribute.
34 2003-03-31 Martin Baulig <martin@ximian.com>
36 * debug.h (MonoDebuggerEvent): Removed
37 MONO_DEBUGGER_EVENT_THREAD_CREATED.
39 * jit.c (mono_thread_start_cb): Don't send the
40 MONO_DEBUGGER_EVENT_THREAD_CREATED event.
42 2003-03-13 Martin Baulig <martin@ximian.com>
44 * debug.c (_mono_debug_address_from_il_offset): Moved to
45 ../metadata/debug-mono-symfile.c
47 2003-03-07 Martin Baulig <martin@ximian.com>
49 * debug-jit.c: #include <config.h>.
51 2003-03-05 Martin Baulig <martin@ximian.com>
53 * debug-jit.c, debug-jit.h: New files. Moved all JIT-specific
56 * debug.c (mono_debug_add_method): Moved to debug-jit.c.
57 (mono_debug_handle, mono_debug_initialized): Made them global.
58 (replace_suffix): Removed, this isn't used anymore.
59 (record_line_number): Moved to debug-jit.c.
60 (debug_generate_method_lines): Moved to debug-jit.c
61 (generate_line_number): Renamed to
62 _mono_debug_generate_line_number() and made it global.
63 (debug_update_il_offsets): Moved to debug-jit.c
64 (mono_debug_get_image): Renamed to _mono_debug_get_image() and made
66 (address_from_il_offset): Renamed to
67 _mono_debug_address_from_il_offset() and made it global.
68 (il_offset_from_position): Moved to debug-jit.c
69 (lookup_method): Renamed to _mono_debug_lookup_method() and made
71 (mono_debug_add_method): Moved to debug-jit.c.
72 (mono_debug_create_notification_function): Use two new functions
73 mono_debug_codegen_breakpoint() and mono_debug_codegen_ret()
74 instead of x86_breakpoint() and x86_ret().
76 Sat Mar 1 12:36:45 CET 2003 Paolo Molaro <lupus@ximian.com>
78 * jit.c: remove unnecessary assert when inlining.
80 2003-02-17 Martin Baulig <martin@ximian.com>
82 * jit.c (mono_jit_compile_method): Don't emit a `nop' at the start
85 2003-02-14 Patrik Torstensson
87 * x86.brg: Implemented CONV_OVF_[I|U]4 (freg), this fixes the issues
88 with the "checked" keyword. Closes bugs #33421 and #35280 (JIT not mint)
90 2003-02-14 Dietmar Maurer <dietmar@ximian.com>
92 * exception.c (mono_arch_find_jit_info): better way to handle
93 situations where we have no MonoJitInfo
95 2003-02-11 Zoltan Varga <vargaz@freemail.hu>
97 * trampoline.c (arch_create_jit_trampoline): This function should
98 allways return a trampoline for managed methods. Fixes bug #29859.
100 2003-02-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
102 * debug.c: allocate debug->source_files. Fixes GLib-CRITICAL upon
105 2003-02-02 Martin Baulig <martin@ximian.com>
107 * debug.c (mono_debug_add_wrapper): Lookup the wrapper method in a
108 hash table; we need to provide the correct code_size.
110 2003-02-02 Martin Baulig <martin@ximian.com>
112 * jit.c (mono_jit_compile_method): Call mono_debug_add_wrapper()
113 to add the interncall to the symbol file.
115 * debug.c (mono_debug_add_wrapper): New public function.
117 2003-02-02 Martin Baulig <martin@ximian.com>
119 * debug.c (debug_update_il_offsets): Set the prologue end address
120 to the address of the first source line.
122 2003-01-31 Dietmar Maurer <dietmar@ximian.com>
124 * jit.c (mono_analyze_stack): use the wrapper signature if necessary
126 2003-01-31 Zoltan Varga <vargaz@freemail.hu>
128 * debug.c (mono_debug_open_image): dynamic assemblies have no debug
131 Thu Jan 30 11:07:06 CET 2003 Paolo Molaro <lupus@ximian.com>
133 * helper.c: handle MONO_TYPE_ARRAY as well.
135 2003-01-29 Dietmar Maurer <dietmar@ximian.com>
137 * jit.c (mono_analyze_stack): impl. CEE_MONO_LDNATIVEOBJ
138 (mono_analyze_stack): RETOBJ always returns native sized objects
140 2003-01-28 Zoltan Varga <vargaz@freemail.hu>
142 * x86.brg (mono_ldintftn): use <= instead of <, since the
143 interface_offsets array is max_interface_id + 1 long.
145 2003-01-28 Dietmar Maurer <dietmar@ximian.com>
147 * x86.brg (mono_ldintftn): fix from Zoltan: use max_interface_id
149 2003-01-27 Zoltan Varga <vargaz@freemail.hu>
151 * exception.c (ves_icall_get_trace): avoid crash if the exception is
154 * exception.c (ves_icall_get_trace): avoid crash on unmanaged frames.
156 2003-01-26 Martin Baulig <martin@ximian.com>
158 * debug.c (mono_debug_init): Take a boolean argument which
159 specifies whether we're running in the Mono Debugger.
161 2003-01-24 Martin Baulig <martin@ximian.com>
163 * debug.c (mono_debug_io_layer): Disable this on Windows.
165 2003-01-23 Dick Porter <dick@ximian.com>
167 * mono.c: Use mono_runtime_exec_managed_code() to run all managed
170 * jit.c: Changed thread start and attach callbacks to pass the
171 thread ID, not the MonoThread pointer. Arrange that managed code
172 execution will fail an assertion in the main thread, just to be
175 2003-01-22 Martin Baulig <martin@ximian.com>
177 * debug.c: Reverted Gonzalo's last change since it is wrong.
178 We're also using the debugging code on Windows, for instance the
179 stabs stuff when running in gdb. I hope this code still builds on
180 Windows; if not, we need to fix this.
181 Moved all the mono debugger support code into the debugger itself;
182 when debugging a managed application, the debugger new launches a
183 small unmanaged wrapper application which contains this stuff.
185 * debug.h (MonoDebuggerIOLayer): New public typedef; this is just
186 initialized to an array of function pointers to the io-layer
187 function; they don't seem to be public in the `libmono' library.
188 (mono_debugger_event): New public function. Sends the debugger an
189 event if we're running in the Mono Debugger and does nothing otherwise.
191 * mono.c: Don't initialize the Mono Debugger here.
193 * jit.c (mono_debug_insert_breakpoint): Removed, this isn't used anymore.
194 (mono_thread_start_cb, mono_thread_attach_cb): Call
195 mono_debugger_event() to send the debugger a callback.
197 2003-01-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
199 * debug.c: make all public symbols just dummy for windows.
201 2003-01-20 Miguel de Icaza <miguel@ximian.com>
203 * debug.c (initialize_debugger_support): ifdef out the call to
204 mono_debugger_init_thread_debug for the release.
206 Someone should look into why its not defined. I think the problem
207 is what Dick pointed out somewhere: code in io-layer is not
208 supposed to ever be used in Windows, so code for the debugger that
209 lives there must be moved elsewhere.
211 2003-01-19 Martin Baulig <martin@ximian.com>
213 * debug.c: Ok, this should now finally be working this time ....
215 2003-01-18 Martin Baulig <martin@ximian.com>
217 * debug.c (mono_debugger_jit_exec): Send the background thread a
218 SIGKILL before returning.
220 2003-01-17 Dietmar Maurer <dietmar@ximian.com>
222 * x86.brg: removed duplicated CONV_OVF_I4
224 2003-01-17 Martin Baulig <martin@ximian.com>
226 * debug.c: Don't use mono_once here. Reworked the API a bit to
227 use `mono_debug_' and `debug_' for the general debugging API and
228 `mono_debugger_' and `debugger_' for the Mono Debugger stuff.
230 2003-01-16 Martin Baulig <martin@ximian.com>
232 * debug.c (debugger_thread_func): We don't need to `raise
233 (SIGSTOP)' anymore; the thread manager already takes care of this.
235 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
237 * exception.c (arch_handle_exception): exclude runtime invoke
238 wrapper from the stack trace
240 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
241 (mono_thread_start_cb): save an additional LMF at thread start
243 2003-01-16 Martin Baulig <martin@ximian.com>
245 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
246 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
247 and the LinuxThreads port doesn't allow you to override the handler.
248 [FIXME: This avoids an assertion failure on startup, but there's
249 still an issue with thread termination.]
251 2003-01-16 Martin Baulig <martin@ximian.com>
253 * debug.c (debugger_thread_func): We don't need to `raise
254 (SIGSTOP)' anymore; the thread manager already takes care of this.
256 2003-01-16 Martin Baulig <martin@ximian.com>
258 * debug.c: Use the mono/io-layer functions here instead of gthread.
260 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
262 * jit.c (mono_jit_compile_method): make sure runtime_init is called
263 (mono_analyze_stack): make sure runtime_init is called
265 2003-01-14 Martin Baulig <martin@ximian.com>
267 * debug.c (debugger_update_symbol_file_table): Moved all the
268 functionality into debugger_update_symbol_file_table_internal();
269 the latter one will be called from the background thread while
270 already owning the lock. This'll allow us to step into
271 debugger_update_symbol_file_table() in the debugger and debug it.
273 2003-01-14 Martin Baulig <martin@ximian.com>
275 * Makefile.am: Link against gthread.
277 * jit.c: After realizing that mono-mutex doesn't work either
278 because it doesn't support recursive mutexes on FreeBSD, rewrote
279 the whole thread stuff to use gthread. This seems to fix this
280 weird deadlock in the debugger as well.
282 2003-01-12 Alp Toker <alp@atoker.com>
284 * exception.c: Typo fix: insinde -> inside
286 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
288 * exception.c (ves_icall_get_frame_info): skip one more frame and also
289 MONO_WRAPPER_RUNTIME_INVOKE wrappers
290 (x86_unwind_native_frame): disable unnecessary assertion
292 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
294 * exception.c (ves_icall_get_frame_info): fix bug 36382
296 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
298 * jit.c: handle wrapper_data in NEWOBJ/CALL.
300 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
302 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
304 2003-01-06 Martin Baulig <martin@ximian.com>
306 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
308 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
309 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
311 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
313 * debug.c: Move must_send_finished var declaration out of #if win32
314 block (this fixes the build on win32)
316 2003-01-05 Martin Baulig <martin@ximian.com>
318 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
319 this is used when we're running inside the Mono Debugger
320 (mono_debugger_wait): Put the waiting code into a function of its own.
322 * mono.c (main): Call mono_debugger_jit_exec() instead of
323 mono_jit_exec() if we're running inside the Mono Debugger.
325 2003-01-05 Martin Baulig <martin@ximian.com>
327 * debug.h (MonoDebugFormat): Added
328 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
329 we're running inside the Mono Debugger prior to the args parsing.
331 2003-01-04 Martin Baulig <martin@ximian.com>
333 * debug.c (release_symbol_file_table): Only call this if we're
334 actually modifying the symbol tables.
335 (mono_debug_open): Always set the `mono_debugger_class_init_func'
336 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
338 2003-01-03 Martin Baulig <martin@ximian.com>
340 * debug.c: Disable the mono debugger stuff on Windows.
342 2003-01-03 Martin Baulig <martin@ximian.com>
344 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
345 function. This is called from the breakpoint trampoline to signal
346 the debugger and wait until it has reload the symbol tables.
348 * trampoline.c (get_breakpoint_trampoline): Call the new
349 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
350 trampoline just before the breakpoint.
352 2002-12-31 Martin Baulig <martin@ximian.com>
354 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
355 field to point to the MonoGlobalSymbolTable.
357 2002-12-30 Martin Baulig <martin@ximian.com>
359 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
360 This variable now specifies that the symbol tables have been
361 modified after the last notification has been send. The debugger
362 uses this flag to check whether it needs to reload the symbol
364 (debugger_compile_method): Just send a notification to the
365 debugger, but don't set the modified flag. It may or may not be
366 set when the debugger gets the notification - depending on whether
367 the JIT compilation added a new method to the symbol tables.
369 2002-12-30 Martin Baulig <martin@ximian.com>
371 * debug.c (debugger_compile_method): This is a wrapper around
372 mono_compile_method() which always sends a notification to the
375 2002-12-30 Martin Baulig <martin@ximian.com>
377 * debug.c: Reload the symbol file table before sending the
378 notification event to the debugger.
379 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
381 2002-12-31 Martin Baulig <martin@ximian.com>
383 * debug.c: Propertly lock everything and avoid race conditions.
384 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
386 2002-12-31 Duncan Mak <duncan@ximian.com>
388 * debug.c (initialize_debugger_support): Fix build error by
389 declaring ret at the top of the function.
391 2002-12-30 Martin Baulig <martin@ximian.com>
393 * debug.c: When running under the mono debugger, create a special
394 debugger thread; always protect the symbol tables with a mutex.
396 2002-12-28 Martin Baulig <martin@ximian.com>
398 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
399 incremented each time one of the symbol tables is modified.
401 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
403 * jit.c: fix LDELEMA implementation here as well.
405 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
407 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
409 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
411 * jit.c: query the thread abort signal from the runtime.
413 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
415 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
417 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
419 * jit.c (mono_analyze_stack): call the utility function
420 mono_field_from_token to avoid code duplication.
422 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
424 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
426 * x86.brg (stmt): POP floating point stack correctly
428 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
430 * emit-x86.c (arch_emit_prologue): don't save caller saved
433 * exception.c (x86_unwind_native_frame): support exceptions inside
434 native code using gcc generated exception tables (-fexception).
436 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
438 * exception.c: include some code from Zoltan Varga, but modified
441 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
443 * exception.c: massive code cleanups. The code is still
444 architecture dependent, but it should be now possible to reuse the
445 complex parts for other architecture.
447 2002-11-15 Dick Porter <dick@ximian.com>
449 * jit.c: Pass the attach callback to mono_runtime_init().
451 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
453 * jit.c: display the domain name in trace output.
455 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
457 * x86.brg (reg): fix bug #2721
459 * jit.c (mono_runtime_install_handlers): impl.
461 2002-10-17 Martin Baulig <martin@gnome.org>
463 * debug.c (mono_debug_add_method): Make this actually work if we don't
464 have any lifetime information.
466 2002-10-15 Martin Baulig <martin@gnome.org>
468 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
470 * debug.c (generate_line_number): Small fix to make this actually
471 work for more complex things.
473 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
475 * x86.brg (freg): use fprem instead of fprem1
477 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
479 * jit.c (ves_array_element_address): added check for out of range index
480 (mono_analyze_stack): added fix for bug #31654
482 2002-10-01 Martin Baulig <martin@gnome.org>
484 * debug.c: Don't create an .il file for the dynamic symbol file.
486 2002-10-01 Martin Baulig <martin@gnome.org>
488 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
490 2002-09-27 Martin Baulig <martin@gnome.org>
492 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
494 2002-09-27 Dick Porter <dick@ximian.com>
496 * mono.c: Tell glib what the program name is, by passing it the
497 name of the managed file we're executing
499 2002-09-26 Martin Baulig <martin@gnome.org>
501 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
502 trampoline into the vtable, also use it for non-virtual methods,
503 remove the breakpoint when done.
505 2002-09-26 Martin Baulig <martin@gnome.org>
507 * debug.c (debug_load_method_lines): Block SIGCHLD while running
510 2002-09-26 Martin Baulig <martin@gnome.org>
512 * debug.c: Reworked the whole debugging stuff. We have now one
513 single `mono_debug_handle' which keeps a hashtable of
514 `AssemblyDebugInfo's (which may have different debugging formats).
515 The AssemblyDebugInfo is now created when the assembly is loaded,
516 but never when adding a class/type.
518 * mono.c: Initialize debugging stuff after corlib and the assembly
521 2002-09-25 Martin Baulig <martin@gnome.org>
523 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
524 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
526 (DebugMethodInfo): Removed `line_numbers'.
528 * debug.c: Reworked the line number generation; we're now using
529 the MonoDebugLineNumberEntry try for all debugging formats. This
530 type also includes the line number and IL offset, this allows the
531 JIT to produce better line number info: we only emit line number
532 information for source lines which actually have code.
534 2002-09-25 Martin Baulig <martin@gnome.org>
536 * debug.h: Removed external declaration of all functions which
537 should only be called from the Mono Debugger and also made them
538 static. Since the debugger gets their address from the
539 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
542 2002-09-25 Martin Baulig <martin@gnome.org>
544 Improved breakpoint support, we can now dynamically insert and
545 remove breakpoints at runtime and when called from withing the
546 Mono Debugger, we're using a special breakpoint trampoline.
548 * debug.h (mono_method_has_breakpoint): New method to check
549 whether to insert a breakpoint for a method.
550 (mono_insert_breakpoint): New method to insert a breakpoint.
551 (mono_insert_breakpoint_full): New method to insert a breakpoint,
552 takes a MonoMethodDesc.
553 (mono_remove_breakpoint): New method to remove a breakpoint.
555 * debug.c (mono_debugger_insert_breakpoint): New function for the
556 debugger. Should only be called from the debugger.
557 (mono_debugger_remove_breakpoint): Likewise.
559 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
561 * trampoline.c (get_breakpoint_trampoline): New static function to
562 create a special breakpoint trampoline for the debugger.
563 (x86_magic_trampoline): If we're running inside the Mono Debugger
564 and a breakpoint was requested for the method, generate a special
565 breakpoint trampoline.
567 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
568 to insert a breakpoint.
569 (mono_debug_last_breakpoint_address): Removed.
570 (match_debug_method): Removed, use mono_method_has_breakpoint().
572 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
574 * jit.c: reorder mono_runtime_cleanup () call since it needs the
575 engine still fully working.
577 2002-09-24 Martin Baulig <martin@gnome.org>
579 * debug.c (mono_debug_open): When we're invoked from inside the
580 Mono Debugger, set mono_debugger_class_init_func (exported in
581 metadata/class.c) to mono_add_type().
582 (mono_add_type): Call mono_debug_symfile_add_type().

658 file name argument; you can now call this before loading the assembly.
659 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
660 we now use MonoSymbolFileLineNumberEntry's and a separate address array
661 instead; splitted out all MonoSymbolFileLineNumberEntry code into
662 debug_generate_il_offsets() and debug_update_il_offsets().
663 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's

795 versions of linuxthreads.
797 * jit.c (mono_runtime_install_handlers): switch back to use

1199 a `MonoAssembly *' argument instead of a `char *filename' one. Also added
1200 `const char **args' argument.
1202 * mono.c (mono_jit_assembly): Renamed to mono_jit_compile_image(), added
1203 `int verbose' argument and made it public.
1204 (mono_jit_compile_class): New public function, moved the code to compile
1205 all methods in a class here from main().
1206 (--compile): The argument can now also be an image (in `@imagename' format).
1207 Updated documentation for this command line argument.

1243 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
1244 file for all assemblies. Currently, the JIT doesn't put all methods
1245 from a single assembly into a continuous region of memory. We were
1246 previously creating valid DWARF 2 files for this, but unfortunately
1247 GDB's symbol tables get messed up when it reads more than one such file.
1249 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',
1250 `next_idx', `methods', `type_hash', `source_files' and `format'

1343 SHL/SHR because the tree allocator can fail otherwise
1345 * exception.c (arch_handle_exception): EIP now points to the call
1346 instruction, not to the instruction after the call. This fixes the
1347 bug reported by Linus Upson (tests/exception8.cs)

1795 2002-03-23 Martin Baulig <martin@gnome.org>
1797 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1798 to do it before the X86_CMP.
1799 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1800 (reg: CLT (lreg, lreg)): Likewise.

1914 (mono_debug_open_file): Added MonoDebugFormat argument.
1915 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1916 this function from GDB. It's now safe to call this function multiple times;
1917 it'll always write a complete debugging file.
1919 * debug.c: Splitted this file into a general part which remains in this file
1920 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1921 All public functions now call a corresponding format specific function.
1923 * debug.c: The following changes are private to debug.c:
1924 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1925 (record_line_number, debug_generate_method_lines): New private functions.
1926 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1927 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1928 mono_debug_open_assembly_dwarf2).
1929 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1930 now safe to call this function multiple times.
1931 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1932 returns an unique index for this type. It's used to ensure that we only write
1933 each class once to the debugging file.
1934 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1935 data structure, but don't directly write to the debugging file. This is done
1936 later from mono_debug_write_assembly().
1938 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1939 debugging output. Call mono_debug_close() on cleanup if necessary.

1943 * debug-private.h: New private header file.
1945 * debug-stabs.c: Added the stabs type generation stuff which was
1946 previously in debug.c.

1949 only writing this most basic types to the dwarf file, but this will
1952 2002-03-13 Martin Baulig <martin@gnome.org>
1954 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1955 debugging code. They're now in CVS, but not yet used anywhere.
1957 2002-03-11 Dietmar Maurer <dietmar@ximian.com>

1965 * jit.c: verify that corlib and runtime are in sync.
1967 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1969 * emit-x86.c, jit.c: use the debug-helpers facilities to
1970 describe and match a method when debugging.
1972 2002-03-10 Martin Baulig <martin@gnome.org>
1974 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1975 output, put a nop instruction at the start of all functions so that
1976 the adresses won't change when using --debug.
1978 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1979 the bytecode area, stabs needs a line number in the .il file. Use the
1980 new info->moffsets to get the line number.
1981 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1982 `moffsets' is an array of `total_lines' fields (total number of lines
1983 in the .il file); for each line in the .il field, this array contains
1984 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1985 of a method and 0 otherwise.
1986 (debug_load_method_lines): Read the whole .il file and initialize the
1987 info->moffsets field.
1989 2002-03-09 Martin Baulig <martin@gnome.org>
1991 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1992 the unnecessary CDQ instruction.
