1 2003-02-02 Martin Baulig <martin@ximian.com>
3 * jit.c (mono_jit_compile_method): Call mono_debug_add_wrapper()
4 to add the interncall to the symbol file.
6 * debug.c (mono_debug_add_wrapper): New public function.
8 2003-02-02 Martin Baulig <martin@ximian.com>
10 * debug.c (debug_update_il_offsets): Set the prologue end address
11 to the address of the first source line.
13 2003-01-31 Dietmar Maurer <dietmar@ximian.com>
15 * jit.c (mono_analyze_stack): use the wrapper signature if necessary
17 2003-01-31 Zoltan Varga <vargaz@freemail.hu>
19 * debug.c (mono_debug_open_image): dynamic assemblies have no debug
22 Thu Jan 30 11:07:06 CET 2003 Paolo Molaro <lupus@ximian.com>
24 * helper.c: handle MONO_TYPE_ARRAY as well.
26 2003-01-29 Dietmar Maurer <dietmar@ximian.com>
28 * jit.c (mono_analyze_stack): impl. CEE_MONO_LDNATIVEOBJ
29 (mono_analyze_stack): RETOBJ always returns native sized objects
31 2003-01-28 Zoltan Varga <vargaz@freemail.hu>
33 * x86.brg (mono_ldintftn): use <= instead of <, since the
34 interface_offsets array is max_interface_id + 1 long.
36 2003-01-28 Dietmar Maurer <dietmar@ximian.com>
38 * x86.brg (mono_ldintftn): fix from Zoltan: use max_interface_id
40 2003-01-27 Zoltan Varga <vargaz@freemail.hu>
42 * exception.c (ves_icall_get_trace): avoid crash if the exception is
45 * exception.c (ves_icall_get_trace): avoid crash on unmanaged frames.
47 2003-01-26 Martin Baulig <martin@ximian.com>
49 * debug.c (mono_debug_init): Take a boolean argument which
50 specifies whether we're running in the Mono Debugger.
52 2003-01-24 Martin Baulig <martin@ximian.com>
54 * debug.c (mono_debug_io_layer): Disable this on Windows.
56 2003-01-23 Dick Porter <dick@ximian.com>
58 * mono.c: Use mono_runtime_exec_managed_code() to run all managed
61 * jit.c: Changed thread start and attach callbacks to pass the
62 thread ID, not the MonoThread pointer. Arrange that managed code
63 execution will fail an assertion in the main thread, just to be
66 2003-01-22 Martin Baulig <martin@ximian.com>
68 * debug.c: Reverted Gonzalo's last change since it is wrong.
69 We're also using the debugging code on Windows, for instance the
70 stabs stuff when running in gdb. I hope this code still builds on
71 Windows; if not, we need to fix this.
72 Moved all the mono debugger support code into the debugger itself;
73 when debugging a managed application, the debugger new launches a
74 small unmanaged wrapper application which contains this stuff.
76 * debug.h (MonoDebuggerIOLayer): New public typedef; this is just
77 initialized to an array of function pointers to the io-layer
78 function; they don't seem to be public in the `libmono' library.
79 (mono_debugger_event): New public function. Sends the debugger an
80 event if we're running in the Mono Debugger and does nothing otherwise.
82 * mono.c: Don't initialize the Mono Debugger here.
84 * jit.c (mono_debug_insert_breakpoint): Removed, this isn't used anymore.
85 (mono_thread_start_cb, mono_thread_attach_cb): Call
86 mono_debugger_event() to send the debugger a callback.
88 2003-01-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
90 * debug.c: make all public symbols just dummy for windows.
92 2003-01-20 Miguel de Icaza <miguel@ximian.com>
94 * debug.c (initialize_debugger_support): ifdef out the call to
95 mono_debugger_init_thread_debug for the release.
97 Someone should look into why its not defined. I think the problem
98 is what Dick pointed out somewhere: code in io-layer is not
99 supposed to ever be used in Windows, so code for the debugger that
100 lives there must be moved elsewhere.
102 2003-01-19 Martin Baulig <martin@ximian.com>
104 * debug.c: Ok, this should now finally be working this time ....
106 2003-01-18 Martin Baulig <martin@ximian.com>
108 * debug.c (mono_debugger_jit_exec): Send the background thread a
109 SIGKILL before returning.
111 2003-01-17 Dietmar Maurer <dietmar@ximian.com>
113 * x86.brg: removed duplicated CONV_OVF_I4
115 2003-01-17 Martin Baulig <martin@ximian.com>
117 * debug.c: Don't use mono_once here. Reworked the API a bit to
118 use `mono_debug_' and `debug_' for the general debugging API and
119 `mono_debugger_' and `debugger_' for the Mono Debugger stuff.
121 2003-01-16 Martin Baulig <martin@ximian.com>
123 * debug.c (debugger_thread_func): We don't need to `raise
124 (SIGSTOP)' anymore; the thread manager already takes care of this.
126 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
128 * exception.c (arch_handle_exception): exclude runtime invoke
129 wrapper from the stack trace
131 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
132 (mono_thread_start_cb): save an additional LMF at thread start
134 2003-01-16 Martin Baulig <martin@ximian.com>
136 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
137 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
138 and the LinuxThreads port doesn't allow you to override the handler.
139 [FIXME: This avoids an assertion failure on startup, but there's
140 still an issue with thread termination.]
142 2003-01-16 Martin Baulig <martin@ximian.com>
144 * debug.c (debugger_thread_func): We don't need to `raise
145 (SIGSTOP)' anymore; the thread manager already takes care of this.
147 2003-01-16 Martin Baulig <martin@ximian.com>
149 * debug.c: Use the mono/io-layer functions here instead of gthread.
151 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
153 * jit.c (mono_jit_compile_method): make sure runtime_init is called
154 (mono_analyze_stack): make sure runtime_init is called
156 2003-01-14 Martin Baulig <martin@ximian.com>
158 * debug.c (debugger_update_symbol_file_table): Moved all the
159 functionality into debugger_update_symbol_file_table_internal();
160 the latter one will be called from the background thread while
161 already owning the lock. This'll allow us to step into
162 debugger_update_symbol_file_table() in the debugger and debug it.
164 2003-01-14 Martin Baulig <martin@ximian.com>
166 * Makefile.am: Link against gthread.
168 * jit.c: After realizing that mono-mutex doesn't work either
169 because it doesn't support recursive mutexes on FreeBSD, rewrote
170 the whole thread stuff to use gthread. This seems to fix this
171 weird deadlock in the debugger as well.
173 2003-01-12 Alp Toker <alp@atoker.com>
175 * exception.c: Typo fix: insinde -> inside
177 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
179 * exception.c (ves_icall_get_frame_info): skip one more frame and also
180 MONO_WRAPPER_RUNTIME_INVOKE wrappers
181 (x86_unwind_native_frame): disable unnecessary assertion
183 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
185 * exception.c (ves_icall_get_frame_info): fix bug 36382
187 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
189 * jit.c: handle wrapper_data in NEWOBJ/CALL.
191 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
193 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
195 2003-01-06 Martin Baulig <martin@ximian.com>
197 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
199 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
200 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
202 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
204 * debug.c: Move must_send_finished var declaration out of #if win32
205 block (this fixes the build on win32)
207 2003-01-05 Martin Baulig <martin@ximian.com>
209 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
210 this is used when we're running inside the Mono Debugger
211 (mono_debugger_wait): Put the waiting code into a function of its own.
213 * mono.c (main): Call mono_debugger_jit_exec() instead of
214 mono_jit_exec() if we're running inside the Mono Debugger.
216 2003-01-05 Martin Baulig <martin@ximian.com>
218 * debug.h (MonoDebugFormat): Added
219 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
220 we're running inside the Mono Debugger prior to the args parsing.
222 2003-01-04 Martin Baulig <martin@ximian.com>
224 * debug.c (release_symbol_file_table): Only call this if we're
225 actually modifying the symbol tables.
226 (mono_debug_open): Always set the `mono_debugger_class_init_func'
227 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
229 2003-01-03 Martin Baulig <martin@ximian.com>
231 * debug.c: Disable the mono debugger stuff on Windows.
233 2003-01-03 Martin Baulig <martin@ximian.com>
235 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
236 function. This is called from the breakpoint trampoline to signal
237 the debugger and wait until it has reload the symbol tables.
239 * trampoline.c (get_breakpoint_trampoline): Call the new
240 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
241 trampoline just before the breakpoint.
243 2002-12-31 Martin Baulig <martin@ximian.com>
245 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
246 field to point to the MonoGlobalSymbolTable.
248 2002-12-30 Martin Baulig <martin@ximian.com>
250 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
251 This variable now specifies that the symbol tables have been
252 modified after the last notification has been send. The debugger
253 uses this flag to check whether it needs to reload the symbol
255 (debugger_compile_method): Just send a notification to the
256 debugger, but don't set the modified flag. It may or may not be
257 set when the debugger gets the notification - depending on whether
258 the JIT compilation added a new method to the symbol tables.
260 2002-12-30 Martin Baulig <martin@ximian.com>
262 * debug.c (debugger_compile_method): This is a wrapper around
263 mono_compile_method() which always sends a notification to the
266 2002-12-30 Martin Baulig <martin@ximian.com>
268 * debug.c: Reload the symbol file table before sending the
269 notification event to the debugger.
270 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
272 2002-12-31 Martin Baulig <martin@ximian.com>
274 * debug.c: Propertly lock everything and avoid race conditions.
275 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
277 2002-12-31 Duncan Mak <duncan@ximian.com>
279 * debug.c (initialize_debugger_support): Fix build error by
280 declaring ret at the top of the function.
282 2002-12-30 Martin Baulig <martin@ximian.com>
284 * debug.c: When running under the mono debugger, create a special
285 debugger thread; always protect the symbol tables with a mutex.
287 2002-12-28 Martin Baulig <martin@ximian.com>
289 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
290 incremented each time one of the symbol tables is modified.
292 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
294 * jit.c: fix LDELEMA implementation here as well.
296 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
298 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
300 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
302 * jit.c: query the thread abort signal from the runtime.
304 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
306 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
308 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
310 * jit.c (mono_analyze_stack): call the utility function
311 mono_field_from_token to avoid code duplication.
313 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
315 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
317 * x86.brg (stmt): POP floating point stack correctly
319 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
321 * emit-x86.c (arch_emit_prologue): don't save caller saved
324 * exception.c (x86_unwind_native_frame): support exceptions inside
325 native code using gcc generated exception tables (-fexception).
327 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
329 * exception.c: include some code from Zoltan Varga, but modified
332 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
334 * exception.c: massive code cleanups. The code is still
335 architecture dependent, but it should be now possible to reuse the
336 complex parts for other architecture.
338 2002-11-15 Dick Porter <dick@ximian.com>
340 * jit.c: Pass the attach callback to mono_runtime_init().
342 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
344 * jit.c: display the domain name in trace output.
346 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
348 * x86.brg (reg): fix bug #2721
350 * jit.c (mono_runtime_install_handlers): impl.
352 2002-10-17 Martin Baulig <martin@gnome.org>
354 * debug.c (mono_debug_add_method): Make this actually work if we don't
355 have any lifetime information.
357 2002-10-15 Martin Baulig <martin@gnome.org>
359 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
361 * debug.c (generate_line_number): Small fix to make this actually
362 work for more complex things.
364 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
366 * x86.brg (freg): use fprem instead of fprem1
368 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
370 * jit.c (ves_array_element_address): added check for out of range index
371 (mono_analyze_stack): added fix for bug #31654
373 2002-10-01 Martin Baulig <martin@gnome.org>
375 * debug.c: Don't create an .il file for the dynamic symbol file.
377 2002-10-01 Martin Baulig <martin@gnome.org>
379 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
381 2002-09-27 Martin Baulig <martin@gnome.org>
383 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
385 2002-09-27 Dick Porter <dick@ximian.com>
387 * mono.c: Tell glib what the program name is, by passing it the
388 name of the managed file we're executing
390 2002-09-26 Martin Baulig <martin@gnome.org>
392 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
393 trampoline into the vtable, also use it for non-virtual methods,
394 remove the breakpoint when done.
396 2002-09-26 Martin Baulig <martin@gnome.org>
398 * debug.c (debug_load_method_lines): Block SIGCHLD while running
401 2002-09-26 Martin Baulig <martin@gnome.org>
403 * debug.c: Reworked the whole debugging stuff. We have now one
404 single `mono_debug_handle' which keeps a hashtable of
405 `AssemblyDebugInfo's (which may have different debugging formats).
406 The AssemblyDebugInfo is now created when the assembly is loaded,
407 but never when adding a class/type.
409 * mono.c: Initialize debugging stuff after corlib and the assembly
412 2002-09-25 Martin Baulig <martin@gnome.org>
414 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
415 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
417 (DebugMethodInfo): Removed `line_numbers'.
419 * debug.c: Reworked the line number generation; we're now using
420 the MonoDebugLineNumberEntry try for all debugging formats. This
421 type also includes the line number and IL offset, this allows the
422 JIT to produce better line number info: we only emit line number
423 information for source lines which actually have code.
425 2002-09-25 Martin Baulig <martin@gnome.org>
427 * debug.h: Removed external declaration of all functions which
428 should only be called from the Mono Debugger and also made them
429 static. Since the debugger gets their address from the
430 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
433 2002-09-25 Martin Baulig <martin@gnome.org>
435 Improved breakpoint support, we can now dynamically insert and
436 remove breakpoints at runtime and when called from withing the
437 Mono Debugger, we're using a special breakpoint trampoline.
439 * debug.h (mono_method_has_breakpoint): New method to check
440 whether to insert a breakpoint for a method.
441 (mono_insert_breakpoint): New method to insert a breakpoint.
442 (mono_insert_breakpoint_full): New method to insert a breakpoint,
443 takes a MonoMethodDesc.
444 (mono_remove_breakpoint): New method to remove a breakpoint.
446 * debug.c (mono_debugger_insert_breakpoint): New function for the
447 debugger. Should only be called from the debugger.
448 (mono_debugger_remove_breakpoint): Likewise.
450 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
452 * trampoline.c (get_breakpoint_trampoline): New static function to
453 create a special breakpoint trampoline for the debugger.
454 (x86_magic_trampoline): If we're running inside the Mono Debugger
455 and a breakpoint was requested for the method, generate a special
456 breakpoint trampoline.
458 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
459 to insert a breakpoint.
460 (mono_debug_last_breakpoint_address): Removed.
461 (match_debug_method): Removed, use mono_method_has_breakpoint().
463 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
465 * jit.c: reorder mono_runtime_cleanup () call since it needs the
466 engine still fully working.
468 2002-09-24 Martin Baulig <martin@gnome.org>
470 * debug.c (mono_debug_open): When we're invoked from inside the
471 Mono Debugger, set mono_debugger_class_init_func (exported in
472 metadata/class.c) to mono_add_type().
473 (mono_add_type): Call mono_debug_symfile_add_type().
475 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
477 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
478 Run finalize on domain cleanup.
479 * mono.c: call setlocale ().
480 * trampoline.c: clearer error message for invalid trampoline.
482 2002-09-21 Martin Baulig <martin@gnome.org>
484 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
485 instead of writing a byte blob.
486 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
487 (mono_debug_add_method): Incrementally add the new method to the symbol
490 * exception.c (arch_handle_exception): If we have debugging support,
491 call mono_debugger_update_symbol_file_table () as well.
493 2002-09-20 Martin Baulig <martin@gnome.org>
495 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
496 the size of the variable.
498 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
500 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
501 iterations if we visit blocks in reverse order.
503 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
505 * jit.c (mono_analyze_stack): cleaup of the array code
507 * exception.c: added patch from Julio Merno to fix bug #30048
509 * jit.c (mono_analyze_stack): code cleanup, fix bug #29365
511 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
513 * x86.brg (LDELEMA): use x86_lea
515 2002-09-06 Martin Baulig <martin@gnome.org>
517 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
518 If you were getting random crashes when using the JIT with debugging
519 turned on, this fixes it.
521 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
523 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
525 2002-09-05 Martin Baulig <martin@gnome.org>
527 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
528 which is read by the debugger.
530 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>
532 * Makefile.am: link libmono directly into mono. Use a ld script
533 to reduce exported symbols.
535 2002-09-03 Martin Baulig <martin@gnome.org>
537 * debug.c (free_method_info): Make this actually work.
539 2002-09-03 Martin Baulig <martin@gnome.org>
541 * debug.h (MonoDebugFormat): Killed MONO_DEBUG_FORMAT_DWARF2_PLUS.
542 * debug-dwarf2-plus.c: Removed.
544 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
545 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
546 `mono_symfile' to `symfile'.
548 * debug.c (mono_debug_open): Replaced the assembly argument with a
549 file name argument; you can now call this before loading the assembly.
550 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
551 we now use MonoSymbolFileLineNumberEntry's and a separate address array
552 instead; splitted out all MonoSymbolFileLineNumberEntry code into
553 debug_generate_il_offsets() and debug_update_il_offsets().
554 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
555 created when reading the symbol file or from debug_load_method_lines().
556 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
558 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before
559 looking up an address.
561 * debug.c: Don't create the .il files for MONO_DEBUG_FORMAT_MONO.
563 * mono.c (main): Initialize debugging before loading the first assembly.
565 2002-08-28 Dick Porter <dick@ximian.com>
567 * mono.c: mono_set_rootdir() doesnt take any args now
569 * Makefile.am: Export HOST_CC for w32 builds
571 2002-08-28 Dietmar Maurer <dietmar@ximian.com>
573 * jit.c (mono_store_tree): only allocate vars if really necessary
575 2002-08-27 Martin Baulig <martin@gnome.org>
577 * debug.c: The mono symbol file is installed together with the assembly
578 it belongs to and it's used on a per-image basis.
580 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>

584 2002-08-27 Martin Baulig <martin@gnome.org>
586 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
587 to use global variables for this since they're stored in a core file.

1040 2002-05-22 Martin Baulig <martin@gnome.org>
1042 * debug-dwarf2.c (dwarf2_write_section_end): Removed. This is not needed
1043 and not supported by all assemblers.

1091 `const char **args' argument.
1093 * mono.c (mono_jit_assembly): Renamed to mono_jit_compile_image(), added
1094 `int verbose' argument and made it public.
1095 (mono_jit_compile_class): New public function, moved the code to compile
1096 all methods in a class here from main().

1114 * debug-dwarf2-plus.c: This is now working again :-)
1116 * debug.c (mono_debug_open_file): When using MONO_DEBUG_FORMAT_DWARF2_PLUS,
1117 we create two MonoDebugHandles: one for MONO_DEBUG_FORMAT_DWARF2_PLUS and

1135 file for all assemblies. Currently, the JIT doesn't put all methods
1136 from a single assembly into a continuous region of memory. We were
1137 previously creating valid DWARF 2 files for this, but unfortunately
1138 GDB's symbol tables get messed up when it reads more than one such file.
1140 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

1155 (mono_debug_open_assembly_stabs): Removed.
1156 (mono_debug_close_assembly_stabs).

1761 2002-03-17 Martin Baulig <martin@gnome.org>
1763 * debug.c (mono_debug_get_type): Recursively call this for all function members
1765 (mono_debug_add_method): Don't mangle function names, this must be done by the
1766 debugger backend if the debugging format needs mangled names.
1768 * debug-dwarf2.c: Improved support for classes, added member functions.
1770 2002-03-16 Martin Baulig <martin@gnome.org>
1772 * debug.c (mono_debug_get_type): Recursively call this for all members and
1773 parent classes of a class type.
1775 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1776 since GDB doesn't like Java very much.
1778 2002-03-16 Martin Baulig <martin@gnome.org>
1780 * debug-dwarf2.c: Added support for enums.
1782 2002-03-15 Martin Baulig <martin@gnome.org>

1803 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1805 (mono_debug_open_file): Added MonoDebugFormat argument.
1806 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1807 this function from GDB. It's now safe to call this function multiple times;
1808 it'll always write a complete debugging file.
1810 * debug.c: Splitted this file into a general part which remains in this file
1811 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1812 All public functions now call a corresponding format specific function.
1814 * debug.c: The following changes are private to debug.c:
1815 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1816 (record_line_number, debug_generate_method_lines): New private functions.
1817 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1818 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1819 mono_debug_open_assembly_dwarf2).
1820 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1821 now safe to call this function multiple times.
1822 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1823 returns an unique index for this type. It's used to ensure that we only write
1824 each class once to the debugging file.
1825 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1826 data structure, but don't directly write to the debugging file. This is done
1827 later from mono_debug_write_assembly().
1829 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1830 debugging output. Call mono_debug_close() on cleanup if necessary.
1832 2002-03-14 Martin Baulig <martin@gnome.org>
1834 * debug-private.h: New private header file.
1836 * debug-stabs.c: Added the stabs type generation stuff which was
1837 previously in debug.c.
1839 * debug-dwarf.c: Started to implement type support. We're currently
1840 only writing this most basic types to the dwarf file, but this will
1843 2002-03-13 Martin Baulig <martin@gnome.org>
1845 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1846 debugging code. They're now in CVS, but not yet used anywhere.
1848 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1850 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*

1856 * jit.c: verify that corlib and runtime are in sync.
1858 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1860 * emit-x86.c, jit.c: use the debug-helpers facilities to
1861 describe and match a method when debugging.
1863 2002-03-10 Martin Baulig <martin@gnome.org>
1865 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1866 output, put a nop instruction at the start of all functions so that
1867 the adresses won't change when using --debug.
1869 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1870 the bytecode area, stabs needs a line number in the .il file. Use the
1871 new info->moffsets to get the line number.
1872 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1873 `moffsets' is an array of `total_lines' fields (total number of lines
1874 in the .il file); for each line in the .il field, this array contains
1875 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1876 of a method and 0 otherwise.
1877 (debug_load_method_lines): Read the whole .il file and initialize the
1878 info->moffsets field.
1880 2002-03-09 Martin Baulig <martin@gnome.org>
1882 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1883 the unnecessary CDQ instruction.
1885 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
