3 * x86.brg: Implemented CONV_OVF_[I|U]4 (freg), this fixes the issues
4 with the "checked" keyword. Closes bugs #33421 and #35280 (JIT not mint)
6 2003-02-14 Dietmar Maurer <dietmar@ximian.com>
8 * exception.c (mono_arch_find_jit_info): better way to handle
9 situations where we have no MonoJitInfo
11 2003-02-11 Zoltan Varga <vargaz@freemail.hu>
13 * trampoline.c (arch_create_jit_trampoline): This function should
14 allways return a trampoline for managed methods. Fixes bug #29859.
16 2003-02-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
18 * debug.c: allocate debug->source_files. Fixes GLib-CRITICAL upon
21 2003-02-02 Martin Baulig <martin@ximian.com>
23 * debug.c (mono_debug_add_wrapper): Lookup the wrapper method in a
24 hash table; we need to provide the correct code_size.
26 2003-02-02 Martin Baulig <martin@ximian.com>
28 * jit.c (mono_jit_compile_method): Call mono_debug_add_wrapper()
29 to add the interncall to the symbol file.
31 * debug.c (mono_debug_add_wrapper): New public function.
33 2003-02-02 Martin Baulig <martin@ximian.com>
35 * debug.c (debug_update_il_offsets): Set the prologue end address
36 to the address of the first source line.
38 2003-01-31 Dietmar Maurer <dietmar@ximian.com>
40 * jit.c (mono_analyze_stack): use the wrapper signature if necessary
42 2003-01-31 Zoltan Varga <vargaz@freemail.hu>
44 * debug.c (mono_debug_open_image): dynamic assemblies have no debug
47 Thu Jan 30 11:07:06 CET 2003 Paolo Molaro <lupus@ximian.com>
49 * helper.c: handle MONO_TYPE_ARRAY as well.
51 2003-01-29 Dietmar Maurer <dietmar@ximian.com>
53 * jit.c (mono_analyze_stack): impl. CEE_MONO_LDNATIVEOBJ
54 (mono_analyze_stack): RETOBJ always returns native sized objects
56 2003-01-28 Zoltan Varga <vargaz@freemail.hu>
58 * x86.brg (mono_ldintftn): use <= instead of <, since the
59 interface_offsets array is max_interface_id + 1 long.
61 2003-01-28 Dietmar Maurer <dietmar@ximian.com>
63 * x86.brg (mono_ldintftn): fix from Zoltan: use max_interface_id
65 2003-01-27 Zoltan Varga <vargaz@freemail.hu>
67 * exception.c (ves_icall_get_trace): avoid crash if the exception is
70 * exception.c (ves_icall_get_trace): avoid crash on unmanaged frames.
72 2003-01-26 Martin Baulig <martin@ximian.com>
74 * debug.c (mono_debug_init): Take a boolean argument which
75 specifies whether we're running in the Mono Debugger.
77 2003-01-24 Martin Baulig <martin@ximian.com>
79 * debug.c (mono_debug_io_layer): Disable this on Windows.
81 2003-01-23 Dick Porter <dick@ximian.com>
83 * mono.c: Use mono_runtime_exec_managed_code() to run all managed
86 * jit.c: Changed thread start and attach callbacks to pass the
87 thread ID, not the MonoThread pointer. Arrange that managed code
88 execution will fail an assertion in the main thread, just to be
91 2003-01-22 Martin Baulig <martin@ximian.com>
93 * debug.c: Reverted Gonzalo's last change since it is wrong.
94 We're also using the debugging code on Windows, for instance the
95 stabs stuff when running in gdb. I hope this code still builds on
96 Windows; if not, we need to fix this.
97 Moved all the mono debugger support code into the debugger itself;
98 when debugging a managed application, the debugger new launches a
99 small unmanaged wrapper application which contains this stuff.
101 * debug.h (MonoDebuggerIOLayer): New public typedef; this is just
102 initialized to an array of function pointers to the io-layer
103 function; they don't seem to be public in the `libmono' library.
104 (mono_debugger_event): New public function. Sends the debugger an
105 event if we're running in the Mono Debugger and does nothing otherwise.
107 * mono.c: Don't initialize the Mono Debugger here.
109 * jit.c (mono_debug_insert_breakpoint): Removed, this isn't used anymore.
110 (mono_thread_start_cb, mono_thread_attach_cb): Call
111 mono_debugger_event() to send the debugger a callback.
113 2003-01-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
115 * debug.c: make all public symbols just dummy for windows.
117 2003-01-20 Miguel de Icaza <miguel@ximian.com>
119 * debug.c (initialize_debugger_support): ifdef out the call to
120 mono_debugger_init_thread_debug for the release.
122 Someone should look into why its not defined. I think the problem
123 is what Dick pointed out somewhere: code in io-layer is not
124 supposed to ever be used in Windows, so code for the debugger that
125 lives there must be moved elsewhere.
127 2003-01-19 Martin Baulig <martin@ximian.com>
129 * debug.c: Ok, this should now finally be working this time ....
131 2003-01-18 Martin Baulig <martin@ximian.com>
133 * debug.c (mono_debugger_jit_exec): Send the background thread a
134 SIGKILL before returning.
136 2003-01-17 Dietmar Maurer <dietmar@ximian.com>
138 * x86.brg: removed duplicated CONV_OVF_I4
140 2003-01-17 Martin Baulig <martin@ximian.com>
142 * debug.c: Don't use mono_once here. Reworked the API a bit to
143 use `mono_debug_' and `debug_' for the general debugging API and
144 `mono_debugger_' and `debugger_' for the Mono Debugger stuff.
146 2003-01-16 Martin Baulig <martin@ximian.com>
148 * debug.c (debugger_thread_func): We don't need to `raise
149 (SIGSTOP)' anymore; the thread manager already takes care of this.
151 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
153 * exception.c (arch_handle_exception): exclude runtime invoke
154 wrapper from the stack trace
156 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
157 (mono_thread_start_cb): save an additional LMF at thread start
159 2003-01-16 Martin Baulig <martin@ximian.com>
161 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
162 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
163 and the LinuxThreads port doesn't allow you to override the handler.
164 [FIXME: This avoids an assertion failure on startup, but there's
165 still an issue with thread termination.]
167 2003-01-16 Martin Baulig <martin@ximian.com>
169 * debug.c (debugger_thread_func): We don't need to `raise
170 (SIGSTOP)' anymore; the thread manager already takes care of this.
172 2003-01-16 Martin Baulig <martin@ximian.com>
174 * debug.c: Use the mono/io-layer functions here instead of gthread.
176 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
178 * jit.c (mono_jit_compile_method): make sure runtime_init is called
179 (mono_analyze_stack): make sure runtime_init is called
181 2003-01-14 Martin Baulig <martin@ximian.com>
183 * debug.c (debugger_update_symbol_file_table): Moved all the
184 functionality into debugger_update_symbol_file_table_internal();
185 the latter one will be called from the background thread while
186 already owning the lock. This'll allow us to step into
187 debugger_update_symbol_file_table() in the debugger and debug it.
189 2003-01-14 Martin Baulig <martin@ximian.com>
191 * Makefile.am: Link against gthread.
193 * jit.c: After realizing that mono-mutex doesn't work either
194 because it doesn't support recursive mutexes on FreeBSD, rewrote
195 the whole thread stuff to use gthread. This seems to fix this
196 weird deadlock in the debugger as well.
198 2003-01-12 Alp Toker <alp@atoker.com>
200 * exception.c: Typo fix: insinde -> inside
202 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
204 * exception.c (ves_icall_get_frame_info): skip one more frame and also
205 MONO_WRAPPER_RUNTIME_INVOKE wrappers
206 (x86_unwind_native_frame): disable unnecessary assertion
208 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
210 * exception.c (ves_icall_get_frame_info): fix bug 36382
212 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
214 * jit.c: handle wrapper_data in NEWOBJ/CALL.
216 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
218 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
220 2003-01-06 Martin Baulig <martin@ximian.com>
222 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
224 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
225 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
227 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
229 * debug.c: Move must_send_finished var declaration out of #if win32
230 block (this fixes the build on win32)
232 2003-01-05 Martin Baulig <martin@ximian.com>
234 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
235 this is used when we're running inside the Mono Debugger
236 (mono_debugger_wait): Put the waiting code into a function of its own.
238 * mono.c (main): Call mono_debugger_jit_exec() instead of
239 mono_jit_exec() if we're running inside the Mono Debugger.
241 2003-01-05 Martin Baulig <martin@ximian.com>
243 * debug.h (MonoDebugFormat): Added
244 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
245 we're running inside the Mono Debugger prior to the args parsing.
247 2003-01-04 Martin Baulig <martin@ximian.com>
249 * debug.c (release_symbol_file_table): Only call this if we're
250 actually modifying the symbol tables.
251 (mono_debug_open): Always set the `mono_debugger_class_init_func'
252 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
254 2003-01-03 Martin Baulig <martin@ximian.com>
256 * debug.c: Disable the mono debugger stuff on Windows.
258 2003-01-03 Martin Baulig <martin@ximian.com>
260 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
261 function. This is called from the breakpoint trampoline to signal
262 the debugger and wait until it has reload the symbol tables.
264 * trampoline.c (get_breakpoint_trampoline): Call the new
265 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
266 trampoline just before the breakpoint.
268 2002-12-31 Martin Baulig <martin@ximian.com>
270 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
271 field to point to the MonoGlobalSymbolTable.
273 2002-12-30 Martin Baulig <martin@ximian.com>
275 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
276 This variable now specifies that the symbol tables have been
277 modified after the last notification has been send. The debugger
278 uses this flag to check whether it needs to reload the symbol
280 (debugger_compile_method): Just send a notification to the
281 debugger, but don't set the modified flag. It may or may not be
282 set when the debugger gets the notification - depending on whether
283 the JIT compilation added a new method to the symbol tables.
285 2002-12-30 Martin Baulig <martin@ximian.com>
287 * debug.c (debugger_compile_method): This is a wrapper around
288 mono_compile_method() which always sends a notification to the
291 2002-12-30 Martin Baulig <martin@ximian.com>
293 * debug.c: Reload the symbol file table before sending the
294 notification event to the debugger.
295 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
297 2002-12-31 Martin Baulig <martin@ximian.com>
299 * debug.c: Propertly lock everything and avoid race conditions.
300 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
302 2002-12-31 Duncan Mak <duncan@ximian.com>
304 * debug.c (initialize_debugger_support): Fix build error by
305 declaring ret at the top of the function.
307 2002-12-30 Martin Baulig <martin@ximian.com>
309 * debug.c: When running under the mono debugger, create a special
310 debugger thread; always protect the symbol tables with a mutex.
312 2002-12-28 Martin Baulig <martin@ximian.com>
314 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
315 incremented each time one of the symbol tables is modified.
317 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
319 * jit.c: fix LDELEMA implementation here as well.
321 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
323 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
325 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
327 * jit.c: query the thread abort signal from the runtime.
329 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
331 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
333 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
335 * jit.c (mono_analyze_stack): call the utility function
336 mono_field_from_token to avoid code duplication.
338 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
340 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
342 * x86.brg (stmt): POP floating point stack correctly
344 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
346 * emit-x86.c (arch_emit_prologue): don't save caller saved
349 * exception.c (x86_unwind_native_frame): support exceptions inside
350 native code using gcc generated exception tables (-fexception).
352 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
354 * exception.c: include some code from Zoltan Varga, but modified
357 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
359 * exception.c: massive code cleanups. The code is still
360 architecture dependent, but it should be now possible to reuse the
361 complex parts for other architecture.
363 2002-11-15 Dick Porter <dick@ximian.com>
365 * jit.c: Pass the attach callback to mono_runtime_init().
367 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
369 * jit.c: display the domain name in trace output.
371 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
373 * x86.brg (reg): fix bug #2721
375 * jit.c (mono_runtime_install_handlers): impl.
377 2002-10-17 Martin Baulig <martin@gnome.org>
379 * debug.c (mono_debug_add_method): Make this actually work if we don't
380 have any lifetime information.
382 2002-10-15 Martin Baulig <martin@gnome.org>
384 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
386 * debug.c (generate_line_number): Small fix to make this actually
387 work for more complex things.
389 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
391 * x86.brg (freg): use fprem instead of fprem1
393 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
395 * jit.c (ves_array_element_address): added check for out of range index
396 (mono_analyze_stack): added fix for bug #31654
398 2002-10-01 Martin Baulig <martin@gnome.org>
400 * debug.c: Don't create an .il file for the dynamic symbol file.
402 2002-10-01 Martin Baulig <martin@gnome.org>
404 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
406 2002-09-27 Martin Baulig <martin@gnome.org>
408 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
410 2002-09-27 Dick Porter <dick@ximian.com>
412 * mono.c: Tell glib what the program name is, by passing it the
413 name of the managed file we're executing
415 2002-09-26 Martin Baulig <martin@gnome.org>
417 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
418 trampoline into the vtable, also use it for non-virtual methods,
419 remove the breakpoint when done.
421 2002-09-26 Martin Baulig <martin@gnome.org>
423 * debug.c (debug_load_method_lines): Block SIGCHLD while running
426 2002-09-26 Martin Baulig <martin@gnome.org>
428 * debug.c: Reworked the whole debugging stuff. We have now one
429 single `mono_debug_handle' which keeps a hashtable of
430 `AssemblyDebugInfo's (which may have different debugging formats).
431 The AssemblyDebugInfo is now created when the assembly is loaded,
432 but never when adding a class/type.
434 * mono.c: Initialize debugging stuff after corlib and the assembly
437 2002-09-25 Martin Baulig <martin@gnome.org>
439 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
440 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
442 (DebugMethodInfo): Removed `line_numbers'.
444 * debug.c: Reworked the line number generation; we're now using
445 the MonoDebugLineNumberEntry try for all debugging formats. This
446 type also includes the line number and IL offset, this allows the
447 JIT to produce better line number info: we only emit line number
448 information for source lines which actually have code.
450 2002-09-25 Martin Baulig <martin@gnome.org>
452 * debug.h: Removed external declaration of all functions which
453 should only be called from the Mono Debugger and also made them
454 static. Since the debugger gets their address from the
455 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
458 2002-09-25 Martin Baulig <martin@gnome.org>
460 Improved breakpoint support, we can now dynamically insert and
461 remove breakpoints at runtime and when called from withing the
462 Mono Debugger, we're using a special breakpoint trampoline.
464 * debug.h (mono_method_has_breakpoint): New method to check
465 whether to insert a breakpoint for a method.
466 (mono_insert_breakpoint): New method to insert a breakpoint.
467 (mono_insert_breakpoint_full): New method to insert a breakpoint,
468 takes a MonoMethodDesc.
469 (mono_remove_breakpoint): New method to remove a breakpoint.
471 * debug.c (mono_debugger_insert_breakpoint): New function for the
472 debugger. Should only be called from the debugger.
473 (mono_debugger_remove_breakpoint): Likewise.
475 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
477 * trampoline.c (get_breakpoint_trampoline): New static function to
478 create a special breakpoint trampoline for the debugger.
479 (x86_magic_trampoline): If we're running inside the Mono Debugger
480 and a breakpoint was requested for the method, generate a special
481 breakpoint trampoline.
483 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
484 to insert a breakpoint.
485 (mono_debug_last_breakpoint_address): Removed.
486 (match_debug_method): Removed, use mono_method_has_breakpoint().
488 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
490 * jit.c: reorder mono_runtime_cleanup () call since it needs the
491 engine still fully working.
493 2002-09-24 Martin Baulig <martin@gnome.org>
495 * debug.c (mono_debug_open): When we're invoked from inside the
496 Mono Debugger, set mono_debugger_class_init_func (exported in
497 metadata/class.c) to mono_add_type().
498 (mono_add_type): Call mono_debug_symfile_add_type().
500 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
502 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
503 Run finalize on domain cleanup.
504 * mono.c: call setlocale ().
505 * trampoline.c: clearer error message for invalid trampoline.
507 2002-09-21 Martin Baulig <martin@gnome.org>
509 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
510 instead of writing a byte blob.
511 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
512 (mono_debug_add_method): Incrementally add the new method to the symbol
515 * exception.c (arch_handle_exception): If we have debugging support,
516 call mono_debugger_update_symbol_file_table () as well.
518 2002-09-20 Martin Baulig <martin@gnome.org>
520 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
521 the size of the variable.
523 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
525 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
526 iterations if we visit blocks in reverse order.
528 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
530 * jit.c (mono_analyze_stack): cleaup of the array code
532 * exception.c: added patch from Julio Merno to fix bug #30048
534 * jit.c (mono_analyze_stack): code cleanup, fix bug #29365
536 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
538 * x86.brg (LDELEMA): use x86_lea
540 2002-09-06 Martin Baulig <martin@gnome.org>
542 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
543 If you were getting random crashes when using the JIT with debugging
544 turned on, this fixes it.
546 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
548 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
550 2002-09-05 Martin Baulig <martin@gnome.org>
552 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
553 which is read by the debugger.
555 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>
557 * Makefile.am: link libmono directly into mono. Use a ld script
558 to reduce exported symbols.
560 2002-09-03 Martin Baulig <martin@gnome.org>
562 * debug.c (free_method_info): Make this actually work.
564 2002-09-03 Martin Baulig <martin@gnome.org>
566 * debug.h (MonoDebugFormat): Killed MONO_DEBUG_FORMAT_DWARF2_PLUS.
567 * debug-dwarf2-plus.c: Removed.
569 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
570 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
571 `mono_symfile' to `symfile'.
573 * debug.c (mono_debug_open): Replaced the assembly argument with a
574 file name argument; you can now call this before loading the assembly.
575 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
576 we now use MonoSymbolFileLineNumberEntry's and a separate address array
577 instead; splitted out all MonoSymbolFileLineNumberEntry code into
578 debug_generate_il_offsets() and debug_update_il_offsets().
579 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
580 created when reading the symbol file or from debug_load_method_lines().
581 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.

609 2002-08-27 Martin Baulig <martin@gnome.org>
611 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need

1118 * mono.c (mono_jit_assembly): Renamed to mono_jit_compile_image(), added
1119 `int verbose' argument and made it public.
1120 (mono_jit_compile_class): New public function, moved the code to compile

1139 * debug-dwarf2-plus.c: This is now working again :-)
1141 * debug.c (mono_debug_open_file): When using MONO_DEBUG_FORMAT_DWARF2_PLUS,

1159 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
1160 file for all assemblies. Currently, the JIT doesn't put all methods
1161 from a single assembly into a continuous region of memory. We were
1162 previously creating valid DWARF 2 files for this, but unfortunately

1830 (mono_debug_open_file): Added MonoDebugFormat argument.
1831 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1832 this function from GDB. It's now safe to call this function multiple times;
1833 it'll always write a complete debugging file.
1835 * debug.c: Splitted this file into a general part which remains in this file
1836 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1837 All public functions now call a corresponding format specific function.
1839 * debug.c: The following changes are private to debug.c:
1840 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1841 (record_line_number, debug_generate_method_lines): New private functions.
1842 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1843 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1844 mono_debug_open_assembly_dwarf2).
1845 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1846 now safe to call this function multiple times.
1847 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1848 returns an unique index for this type. It's used to ensure that we only write
1849 each class once to the debugging file.
1850 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1851 data structure, but don't directly write to the debugging file. This is done
1852 later from mono_debug_write_assembly().
1854 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1855 debugging output. Call mono_debug_close() on cleanup if necessary.
1857 2002-03-14 Martin Baulig <martin@gnome.org>
1859 * debug-private.h: New private header file.
1861 * debug-stabs.c: Added the stabs type generation stuff which was
1862 previously in debug.c.
1864 * debug-dwarf.c: Started to implement type support. We're currently
1865 only writing this most basic types to the dwarf file, but this will
1868 2002-03-13 Martin Baulig <martin@gnome.org>
1870 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1871 debugging code. They're now in CVS, but not yet used anywhere.
1873 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1875 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*

1881 * jit.c: verify that corlib and runtime are in sync.
1883 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1885 * emit-x86.c, jit.c: use the debug-helpers facilities to
1886 describe and match a method when debugging.
1888 2002-03-10 Martin Baulig <martin@gnome.org>
1890 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1891 output, put a nop instruction at the start of all functions so that
1892 the adresses won't change when using --debug.
1894 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1895 the bytecode area, stabs needs a line number in the .il file. Use the
1896 new info->moffsets to get the line number.
1897 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1898 `moffsets' is an array of `total_lines' fields (total number of lines
1899 in the .il file); for each line in the .il field, this array contains
1900 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1901 of a method and 0 otherwise.
1902 (debug_load_method_lines): Read the whole .il file and initialize the
1903 info->moffsets field.
1905 2002-03-09 Martin Baulig <martin@gnome.org>
1907 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1908 the unnecessary CDQ instruction.
