1 2003-04-23 Martin Baulig <martin@ximian.com>
3 * mono.c: The `--debug' command line argument doesn't take any
4 arguments anymore, removed the `--debug-args' argument.
6 * debug-jit.c (mono_debug_add_method): Renamed this to
7 mono_debug_jit_add_method(); create the JIT-specific data
8 structure and pass it to mono_debug_add_method().
10 * debug.[ch]: Removed. The code is now in
11 ../metadata/mono-debug.[ch] and mono-debug-debugger.[ch].
13 * debug-stabs.c, debug-dwarf2.c: Removed; nobody used this for the
16 2003-04-21 Martin Baulig <martin@ximian.com>
18 * debug.c (mono_debug_open): Splitted into mono_debug_init() and
20 (mono_debug_open_image): Don't open referenced assemblies; this is
21 done automatically by the code in assembly.c.
23 * mono.c (main_thread_handler): Call mono_debug_init() before
24 opening the assembly because we need to install the assembly load
27 2003-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
30 (mono_jit_cleanup): moved mono_runtime_cleanup call after the call to
33 2003-04-05 Miguel de Icaza <miguel@ximian.com>
35 * jit.c (check_inlining): honor the NOINLING atttribute.
37 2003-03-31 Martin Baulig <martin@ximian.com>
39 * debug.h (MonoDebuggerEvent): Removed
40 MONO_DEBUGGER_EVENT_THREAD_CREATED.
42 * jit.c (mono_thread_start_cb): Don't send the
43 MONO_DEBUGGER_EVENT_THREAD_CREATED event.
45 2003-03-13 Martin Baulig <martin@ximian.com>
47 * debug.c (_mono_debug_address_from_il_offset): Moved to
48 ../metadata/debug-mono-symfile.c
50 2003-03-07 Martin Baulig <martin@ximian.com>
52 * debug-jit.c: #include <config.h>.
54 2003-03-05 Martin Baulig <martin@ximian.com>
56 * debug-jit.c, debug-jit.h: New files. Moved all JIT-specific
59 * debug.c (mono_debug_add_method): Moved to debug-jit.c.
60 (mono_debug_handle, mono_debug_initialized): Made them global.
61 (replace_suffix): Removed, this isn't used anymore.
62 (record_line_number): Moved to debug-jit.c.
63 (debug_generate_method_lines): Moved to debug-jit.c
64 (generate_line_number): Renamed to
65 _mono_debug_generate_line_number() and made it global.
66 (debug_update_il_offsets): Moved to debug-jit.c
67 (mono_debug_get_image): Renamed to _mono_debug_get_image() and made
69 (address_from_il_offset): Renamed to
70 _mono_debug_address_from_il_offset() and made it global.
71 (il_offset_from_position): Moved to debug-jit.c
72 (lookup_method): Renamed to _mono_debug_lookup_method() and made
74 (mono_debug_add_method): Moved to debug-jit.c.
75 (mono_debug_create_notification_function): Use two new functions
76 mono_debug_codegen_breakpoint() and mono_debug_codegen_ret()
77 instead of x86_breakpoint() and x86_ret().
79 Sat Mar 1 12:36:45 CET 2003 Paolo Molaro <lupus@ximian.com>
81 * jit.c: remove unnecessary assert when inlining.
83 2003-02-17 Martin Baulig <martin@ximian.com>
85 * jit.c (mono_jit_compile_method): Don't emit a `nop' at the start
88 2003-02-14 Patrik Torstensson
90 * x86.brg: Implemented CONV_OVF_[I|U]4 (freg), this fixes the issues
91 with the "checked" keyword. Closes bugs #33421 and #35280 (JIT not mint)
93 2003-02-14 Dietmar Maurer <dietmar@ximian.com>
95 * exception.c (mono_arch_find_jit_info): better way to handle
96 situations where we have no MonoJitInfo
98 2003-02-11 Zoltan Varga <vargaz@freemail.hu>
100 * trampoline.c (arch_create_jit_trampoline): This function should
101 allways return a trampoline for managed methods. Fixes bug #29859.
103 2003-02-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
105 * debug.c: allocate debug->source_files. Fixes GLib-CRITICAL upon
108 2003-02-02 Martin Baulig <martin@ximian.com>
110 * debug.c (mono_debug_add_wrapper): Lookup the wrapper method in a
111 hash table; we need to provide the correct code_size.
113 2003-02-02 Martin Baulig <martin@ximian.com>
115 * jit.c (mono_jit_compile_method): Call mono_debug_add_wrapper()
116 to add the interncall to the symbol file.
118 * debug.c (mono_debug_add_wrapper): New public function.
120 2003-02-02 Martin Baulig <martin@ximian.com>
122 * debug.c (debug_update_il_offsets): Set the prologue end address
123 to the address of the first source line.
125 2003-01-31 Dietmar Maurer <dietmar@ximian.com>
127 * jit.c (mono_analyze_stack): use the wrapper signature if necessary
129 2003-01-31 Zoltan Varga <vargaz@freemail.hu>
131 * debug.c (mono_debug_open_image): dynamic assemblies have no debug
134 Thu Jan 30 11:07:06 CET 2003 Paolo Molaro <lupus@ximian.com>
136 * helper.c: handle MONO_TYPE_ARRAY as well.
138 2003-01-29 Dietmar Maurer <dietmar@ximian.com>
140 * jit.c (mono_analyze_stack): impl. CEE_MONO_LDNATIVEOBJ
141 (mono_analyze_stack): RETOBJ always returns native sized objects
143 2003-01-28 Zoltan Varga <vargaz@freemail.hu>
145 * x86.brg (mono_ldintftn): use <= instead of <, since the
146 interface_offsets array is max_interface_id + 1 long.
148 2003-01-28 Dietmar Maurer <dietmar@ximian.com>
150 * x86.brg (mono_ldintftn): fix from Zoltan: use max_interface_id
152 2003-01-27 Zoltan Varga <vargaz@freemail.hu>
154 * exception.c (ves_icall_get_trace): avoid crash if the exception is
157 * exception.c (ves_icall_get_trace): avoid crash on unmanaged frames.
159 2003-01-26 Martin Baulig <martin@ximian.com>
161 * debug.c (mono_debug_init): Take a boolean argument which
162 specifies whether we're running in the Mono Debugger.
164 2003-01-24 Martin Baulig <martin@ximian.com>
166 * debug.c (mono_debug_io_layer): Disable this on Windows.
168 2003-01-23 Dick Porter <dick@ximian.com>
170 * mono.c: Use mono_runtime_exec_managed_code() to run all managed
173 * jit.c: Changed thread start and attach callbacks to pass the
174 thread ID, not the MonoThread pointer. Arrange that managed code
175 execution will fail an assertion in the main thread, just to be
178 2003-01-22 Martin Baulig <martin@ximian.com>
180 * debug.c: Reverted Gonzalo's last change since it is wrong.
181 We're also using the debugging code on Windows, for instance the
182 stabs stuff when running in gdb. I hope this code still builds on
183 Windows; if not, we need to fix this.
184 Moved all the mono debugger support code into the debugger itself;
185 when debugging a managed application, the debugger new launches a
186 small unmanaged wrapper application which contains this stuff.
188 * debug.h (MonoDebuggerIOLayer): New public typedef; this is just
189 initialized to an array of function pointers to the io-layer
190 function; they don't seem to be public in the `libmono' library.
191 (mono_debugger_event): New public function. Sends the debugger an
192 event if we're running in the Mono Debugger and does nothing otherwise.
194 * mono.c: Don't initialize the Mono Debugger here.
196 * jit.c (mono_debug_insert_breakpoint): Removed, this isn't used anymore.
197 (mono_thread_start_cb, mono_thread_attach_cb): Call
198 mono_debugger_event() to send the debugger a callback.
200 2003-01-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
202 * debug.c: make all public symbols just dummy for windows.
204 2003-01-20 Miguel de Icaza <miguel@ximian.com>
206 * debug.c (initialize_debugger_support): ifdef out the call to
207 mono_debugger_init_thread_debug for the release.
209 Someone should look into why its not defined. I think the problem
210 is what Dick pointed out somewhere: code in io-layer is not
211 supposed to ever be used in Windows, so code for the debugger that
212 lives there must be moved elsewhere.
214 2003-01-19 Martin Baulig <martin@ximian.com>
216 * debug.c: Ok, this should now finally be working this time ....
218 2003-01-18 Martin Baulig <martin@ximian.com>
220 * debug.c (mono_debugger_jit_exec): Send the background thread a
221 SIGKILL before returning.
223 2003-01-17 Dietmar Maurer <dietmar@ximian.com>
225 * x86.brg: removed duplicated CONV_OVF_I4
227 2003-01-17 Martin Baulig <martin@ximian.com>
229 * debug.c: Don't use mono_once here. Reworked the API a bit to
230 use `mono_debug_' and `debug_' for the general debugging API and
231 `mono_debugger_' and `debugger_' for the Mono Debugger stuff.
233 2003-01-16 Martin Baulig <martin@ximian.com>
235 * debug.c (debugger_thread_func): We don't need to `raise
236 (SIGSTOP)' anymore; the thread manager already takes care of this.
238 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
240 * exception.c (arch_handle_exception): exclude runtime invoke
241 wrapper from the stack trace
243 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
244 (mono_thread_start_cb): save an additional LMF at thread start
246 2003-01-16 Martin Baulig <martin@ximian.com>
248 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
249 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
250 and the LinuxThreads port doesn't allow you to override the handler.
251 [FIXME: This avoids an assertion failure on startup, but there's
252 still an issue with thread termination.]
254 2003-01-16 Martin Baulig <martin@ximian.com>
256 * debug.c (debugger_thread_func): We don't need to `raise
257 (SIGSTOP)' anymore; the thread manager already takes care of this.
259 2003-01-16 Martin Baulig <martin@ximian.com>
261 * debug.c: Use the mono/io-layer functions here instead of gthread.
263 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
265 * jit.c (mono_jit_compile_method): make sure runtime_init is called
266 (mono_analyze_stack): make sure runtime_init is called
268 2003-01-14 Martin Baulig <martin@ximian.com>
270 * debug.c (debugger_update_symbol_file_table): Moved all the
271 functionality into debugger_update_symbol_file_table_internal();
272 the latter one will be called from the background thread while
273 already owning the lock. This'll allow us to step into
274 debugger_update_symbol_file_table() in the debugger and debug it.
276 2003-01-14 Martin Baulig <martin@ximian.com>
278 * Makefile.am: Link against gthread.
280 * jit.c: After realizing that mono-mutex doesn't work either
281 because it doesn't support recursive mutexes on FreeBSD, rewrote
282 the whole thread stuff to use gthread. This seems to fix this
283 weird deadlock in the debugger as well.
285 2003-01-12 Alp Toker <alp@atoker.com>
287 * exception.c: Typo fix: insinde -> inside
289 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
291 * exception.c (ves_icall_get_frame_info): skip one more frame and also
292 MONO_WRAPPER_RUNTIME_INVOKE wrappers
293 (x86_unwind_native_frame): disable unnecessary assertion
295 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
297 * exception.c (ves_icall_get_frame_info): fix bug 36382
299 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
301 * jit.c: handle wrapper_data in NEWOBJ/CALL.
303 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
305 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
307 2003-01-06 Martin Baulig <martin@ximian.com>
309 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
311 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
312 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
314 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
316 * debug.c: Move must_send_finished var declaration out of #if win32
317 block (this fixes the build on win32)
319 2003-01-05 Martin Baulig <martin@ximian.com>
321 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
322 this is used when we're running inside the Mono Debugger
323 (mono_debugger_wait): Put the waiting code into a function of its own.
325 * mono.c (main): Call mono_debugger_jit_exec() instead of
326 mono_jit_exec() if we're running inside the Mono Debugger.
328 2003-01-05 Martin Baulig <martin@ximian.com>
330 * debug.h (MonoDebugFormat): Added
331 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
332 we're running inside the Mono Debugger prior to the args parsing.
334 2003-01-04 Martin Baulig <martin@ximian.com>
336 * debug.c (release_symbol_file_table): Only call this if we're
337 actually modifying the symbol tables.
338 (mono_debug_open): Always set the `mono_debugger_class_init_func'
339 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
341 2003-01-03 Martin Baulig <martin@ximian.com>
343 * debug.c: Disable the mono debugger stuff on Windows.
345 2003-01-03 Martin Baulig <martin@ximian.com>
347 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
348 function. This is called from the breakpoint trampoline to signal
349 the debugger and wait until it has reload the symbol tables.
351 * trampoline.c (get_breakpoint_trampoline): Call the new
352 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
353 trampoline just before the breakpoint.
355 2002-12-31 Martin Baulig <martin@ximian.com>
357 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
358 field to point to the MonoGlobalSymbolTable.
360 2002-12-30 Martin Baulig <martin@ximian.com>
362 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
363 This variable now specifies that the symbol tables have been
364 modified after the last notification has been send. The debugger
365 uses this flag to check whether it needs to reload the symbol
367 (debugger_compile_method): Just send a notification to the
368 debugger, but don't set the modified flag. It may or may not be
369 set when the debugger gets the notification - depending on whether
370 the JIT compilation added a new method to the symbol tables.
372 2002-12-30 Martin Baulig <martin@ximian.com>
374 * debug.c (debugger_compile_method): This is a wrapper around
375 mono_compile_method() which always sends a notification to the
378 2002-12-30 Martin Baulig <martin@ximian.com>
380 * debug.c: Reload the symbol file table before sending the
381 notification event to the debugger.
382 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
384 2002-12-31 Martin Baulig <martin@ximian.com>
386 * debug.c: Propertly lock everything and avoid race conditions.
387 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
389 2002-12-31 Duncan Mak <duncan@ximian.com>
391 * debug.c (initialize_debugger_support): Fix build error by
392 declaring ret at the top of the function.
394 2002-12-30 Martin Baulig <martin@ximian.com>
396 * debug.c: When running under the mono debugger, create a special
397 debugger thread; always protect the symbol tables with a mutex.
399 2002-12-28 Martin Baulig <martin@ximian.com>
401 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
402 incremented each time one of the symbol tables is modified.
404 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
406 * jit.c: fix LDELEMA implementation here as well.
408 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
410 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
412 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
414 * jit.c: query the thread abort signal from the runtime.
416 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
418 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
420 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
422 * jit.c (mono_analyze_stack): call the utility function
423 mono_field_from_token to avoid code duplication.
425 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
427 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
429 * x86.brg (stmt): POP floating point stack correctly
431 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
433 * emit-x86.c (arch_emit_prologue): don't save caller saved
436 * exception.c (x86_unwind_native_frame): support exceptions inside
437 native code using gcc generated exception tables (-fexception).
439 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
441 * exception.c: include some code from Zoltan Varga, but modified
444 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
446 * exception.c: massive code cleanups. The code is still
447 architecture dependent, but it should be now possible to reuse the
448 complex parts for other architecture.
450 2002-11-15 Dick Porter <dick@ximian.com>
452 * jit.c: Pass the attach callback to mono_runtime_init().
454 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
456 * jit.c: display the domain name in trace output.
458 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
460 * x86.brg (reg): fix bug #2721
462 * jit.c (mono_runtime_install_handlers): impl.
464 2002-10-17 Martin Baulig <martin@gnome.org>
466 * debug.c (mono_debug_add_method): Make this actually work if we don't
467 have any lifetime information.
469 2002-10-15 Martin Baulig <martin@gnome.org>
471 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
473 * debug.c (generate_line_number): Small fix to make this actually
474 work for more complex things.
476 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
478 * x86.brg (freg): use fprem instead of fprem1
480 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
482 * jit.c (ves_array_element_address): added check for out of range index
483 (mono_analyze_stack): added fix for bug #31654
485 2002-10-01 Martin Baulig <martin@gnome.org>
487 * debug.c: Don't create an .il file for the dynamic symbol file.
489 2002-10-01 Martin Baulig <martin@gnome.org>
491 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
493 2002-09-27 Martin Baulig <martin@gnome.org>
495 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
497 2002-09-27 Dick Porter <dick@ximian.com>
499 * mono.c: Tell glib what the program name is, by passing it the
500 name of the managed file we're executing
502 2002-09-26 Martin Baulig <martin@gnome.org>
504 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
505 trampoline into the vtable, also use it for non-virtual methods,
506 remove the breakpoint when done.
508 2002-09-26 Martin Baulig <martin@gnome.org>
510 * debug.c (debug_load_method_lines): Block SIGCHLD while running
513 2002-09-26 Martin Baulig <martin@gnome.org>
515 * debug.c: Reworked the whole debugging stuff. We have now one
516 single `mono_debug_handle' which keeps a hashtable of
517 `AssemblyDebugInfo's (which may have different debugging formats).
518 The AssemblyDebugInfo is now created when the assembly is loaded,
519 but never when adding a class/type.
521 * mono.c: Initialize debugging stuff after corlib and the assembly
524 2002-09-25 Martin Baulig <martin@gnome.org>
526 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
527 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
529 (DebugMethodInfo): Removed `line_numbers'.
531 * debug.c: Reworked the line number generation; we're now using
532 the MonoDebugLineNumberEntry try for all debugging formats. This
533 type also includes the line number and IL offset, this allows the
534 JIT to produce better line number info: we only emit line number
535 information for source lines which actually have code.
537 2002-09-25 Martin Baulig <martin@gnome.org>
539 * debug.h: Removed external declaration of all functions which
540 should only be called from the Mono Debugger and also made them
541 static. Since the debugger gets their address from the
542 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
545 2002-09-25 Martin Baulig <martin@gnome.org>
547 Improved breakpoint support, we can now dynamically insert and
548 remove breakpoints at runtime and when called from withing the
549 Mono Debugger, we're using a special breakpoint trampoline.
551 * debug.h (mono_method_has_breakpoint): New method to check
552 whether to insert a breakpoint for a method.
553 (mono_insert_breakpoint): New method to insert a breakpoint.
554 (mono_insert_breakpoint_full): New method to insert a breakpoint,
555 takes a MonoMethodDesc.
556 (mono_remove_breakpoint): New method to remove a breakpoint.
558 * debug.c (mono_debugger_insert_breakpoint): New function for the
559 debugger. Should only be called from the debugger.
560 (mono_debugger_remove_breakpoint): Likewise.
562 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
564 * trampoline.c (get_breakpoint_trampoline): New static function to
565 create a special breakpoint trampoline for the debugger.
566 (x86_magic_trampoline): If we're running inside the Mono Debugger
567 and a breakpoint was requested for the method, generate a special
568 breakpoint trampoline.
570 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
571 to insert a breakpoint.
572 (mono_debug_last_breakpoint_address): Removed.
573 (match_debug_method): Removed, use mono_method_has_breakpoint().
575 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
577 * jit.c: reorder mono_runtime_cleanup () call since it needs the
578 engine still fully working.
580 2002-09-24 Martin Baulig <martin@gnome.org>
582 * debug.c (mono_debug_open): When we're invoked from inside the
583 Mono Debugger, set mono_debugger_class_init_func (exported in

1202 a `MonoAssembly *' argument instead of a `char *filename' one. Also added
1203 `const char **args' argument.
1205 * mono.c (mono_jit_assembly): Renamed to mono_jit_compile_image(), added
1206 `int verbose' argument and made it public.
1207 (mono_jit_compile_class): New public function, moved the code to compile
1208 all methods in a class here from main().
1209 (--compile): The argument can now also be an image (in `@imagename' format).
1210 Updated documentation for this command line argument.
1211 (--precompile): New command line argument to precompile an image/class/method
1212 before executing the main app. This argument can be given multiple times.

1246 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
1247 file for all assemblies. Currently, the JIT doesn't put all methods
1248 from a single assembly into a continuous region of memory. We were
1249 previously creating valid DWARF 2 files for this, but unfortunately
1250 GDB's symbol tables get messed up when it reads more than one such file.
1252 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',
1253 `next_idx', `methods', `type_hash', `source_files' and `format'
1254 into the MonoDebugHandle.

1267 (mono_debug_open_assembly_stabs): Removed.
1268 (mono_debug_close_assembly_stabs).

1346 SHL/SHR because the tree allocator can fail otherwise
1348 * exception.c (arch_handle_exception): EIP now points to the call
1349 instruction, not to the instruction after the call. This fixes the
1350 bug reported by Linus Upson (tests/exception8.cs)

1798 2002-03-23 Martin Baulig <martin@gnome.org>
1800 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1801 to do it before the X86_CMP.
1802 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1803 (reg: CLT (lreg, lreg)): Likewise.

1917 (mono_debug_open_file): Added MonoDebugFormat argument.
1918 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1919 this function from GDB. It's now safe to call this function multiple times;
1920 it'll always write a complete debugging file.
1922 * debug.c: Splitted this file into a general part which remains in this file
1923 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1924 All public functions now call a corresponding format specific function.
1926 * debug.c: The following changes are private to debug.c:
1927 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1928 (record_line_number, debug_generate_method_lines): New private functions.
1929 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1930 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1931 mono_debug_open_assembly_dwarf2).
1932 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1933 now safe to call this function multiple times.
1934 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1935 returns an unique index for this type. It's used to ensure that we only write
1936 each class once to the debugging file.
1937 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1938 data structure, but don't directly write to the debugging file. This is done
1939 later from mono_debug_write_assembly().
1941 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1942 debugging output. Call mono_debug_close() on cleanup if necessary.

1946 * debug-private.h: New private header file.
1948 * debug-stabs.c: Added the stabs type generation stuff which was
1949 previously in debug.c.

1952 only writing this most basic types to the dwarf file, but this will
1955 2002-03-13 Martin Baulig <martin@gnome.org>
1957 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1958 debugging code. They're now in CVS, but not yet used anywhere.
1960 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1962 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*

1968 * jit.c: verify that corlib and runtime are in sync.
1970 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1972 * emit-x86.c, jit.c: use the debug-helpers facilities to
1973 describe and match a method when debugging.
1975 2002-03-10 Martin Baulig <martin@gnome.org>
1977 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1978 output, put a nop instruction at the start of all functions so that
1979 the adresses won't change when using --debug.
1981 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1982 the bytecode area, stabs needs a line number in the .il file. Use the
1983 new info->moffsets to get the line number.
1984 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1985 `moffsets' is an array of `total_lines' fields (total number of lines
1986 in the .il file); for each line in the .il field, this array contains
1987 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1988 of a method and 0 otherwise.
1989 (debug_load_method_lines): Read the whole .il file and initialize the
1990 info->moffsets field.
1992 2002-03-09 Martin Baulig <martin@gnome.org>
1994 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1995 the unnecessary CDQ instruction.
1997 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
