1 2003-04-21 Martin Baulig <martin@ximian.com>
3 * debug.c (mono_debug_open): Splitted into mono_debug_init() and
5 (mono_debug_open_image): Don't open referenced assemblies; this is
6 done automatically by the code in assembly.c.
8 * mono.c (main_thread_handler): Call mono_debug_init() before
9 opening the assembly because we need to install the assembly load
12 2003-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
15 (mono_jit_cleanup): moved mono_runtime_cleanup call after the call to
18 2003-04-05 Miguel de Icaza <miguel@ximian.com>
20 * jit.c (check_inlining): honor the NOINLING atttribute.
22 2003-03-31 Martin Baulig <martin@ximian.com>
24 * debug.h (MonoDebuggerEvent): Removed
25 MONO_DEBUGGER_EVENT_THREAD_CREATED.
27 * jit.c (mono_thread_start_cb): Don't send the
28 MONO_DEBUGGER_EVENT_THREAD_CREATED event.
30 2003-03-13 Martin Baulig <martin@ximian.com>
32 * debug.c (_mono_debug_address_from_il_offset): Moved to
33 ../metadata/debug-mono-symfile.c
35 2003-03-07 Martin Baulig <martin@ximian.com>
37 * debug-jit.c: #include <config.h>.
39 2003-03-05 Martin Baulig <martin@ximian.com>
41 * debug-jit.c, debug-jit.h: New files. Moved all JIT-specific
44 * debug.c (mono_debug_add_method): Moved to debug-jit.c.
45 (mono_debug_handle, mono_debug_initialized): Made them global.
46 (replace_suffix): Removed, this isn't used anymore.
47 (record_line_number): Moved to debug-jit.c.
48 (debug_generate_method_lines): Moved to debug-jit.c
49 (generate_line_number): Renamed to
50 _mono_debug_generate_line_number() and made it global.
51 (debug_update_il_offsets): Moved to debug-jit.c
52 (mono_debug_get_image): Renamed to _mono_debug_get_image() and made
54 (address_from_il_offset): Renamed to
55 _mono_debug_address_from_il_offset() and made it global.
56 (il_offset_from_position): Moved to debug-jit.c
57 (lookup_method): Renamed to _mono_debug_lookup_method() and made
59 (mono_debug_add_method): Moved to debug-jit.c.
60 (mono_debug_create_notification_function): Use two new functions
61 mono_debug_codegen_breakpoint() and mono_debug_codegen_ret()
62 instead of x86_breakpoint() and x86_ret().
64 Sat Mar 1 12:36:45 CET 2003 Paolo Molaro <lupus@ximian.com>
66 * jit.c: remove unnecessary assert when inlining.
68 2003-02-17 Martin Baulig <martin@ximian.com>
70 * jit.c (mono_jit_compile_method): Don't emit a `nop' at the start
73 2003-02-14 Patrik Torstensson
75 * x86.brg: Implemented CONV_OVF_[I|U]4 (freg), this fixes the issues
76 with the "checked" keyword. Closes bugs #33421 and #35280 (JIT not mint)
78 2003-02-14 Dietmar Maurer <dietmar@ximian.com>
80 * exception.c (mono_arch_find_jit_info): better way to handle
81 situations where we have no MonoJitInfo
83 2003-02-11 Zoltan Varga <vargaz@freemail.hu>
85 * trampoline.c (arch_create_jit_trampoline): This function should
86 allways return a trampoline for managed methods. Fixes bug #29859.
88 2003-02-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
90 * debug.c: allocate debug->source_files. Fixes GLib-CRITICAL upon
93 2003-02-02 Martin Baulig <martin@ximian.com>
95 * debug.c (mono_debug_add_wrapper): Lookup the wrapper method in a
96 hash table; we need to provide the correct code_size.
98 2003-02-02 Martin Baulig <martin@ximian.com>
100 * jit.c (mono_jit_compile_method): Call mono_debug_add_wrapper()
101 to add the interncall to the symbol file.
103 * debug.c (mono_debug_add_wrapper): New public function.
105 2003-02-02 Martin Baulig <martin@ximian.com>
107 * debug.c (debug_update_il_offsets): Set the prologue end address
108 to the address of the first source line.
110 2003-01-31 Dietmar Maurer <dietmar@ximian.com>
112 * jit.c (mono_analyze_stack): use the wrapper signature if necessary
114 2003-01-31 Zoltan Varga <vargaz@freemail.hu>
116 * debug.c (mono_debug_open_image): dynamic assemblies have no debug
119 Thu Jan 30 11:07:06 CET 2003 Paolo Molaro <lupus@ximian.com>
121 * helper.c: handle MONO_TYPE_ARRAY as well.
123 2003-01-29 Dietmar Maurer <dietmar@ximian.com>
125 * jit.c (mono_analyze_stack): impl. CEE_MONO_LDNATIVEOBJ
126 (mono_analyze_stack): RETOBJ always returns native sized objects
128 2003-01-28 Zoltan Varga <vargaz@freemail.hu>
130 * x86.brg (mono_ldintftn): use <= instead of <, since the
131 interface_offsets array is max_interface_id + 1 long.
133 2003-01-28 Dietmar Maurer <dietmar@ximian.com>
135 * x86.brg (mono_ldintftn): fix from Zoltan: use max_interface_id
137 2003-01-27 Zoltan Varga <vargaz@freemail.hu>
139 * exception.c (ves_icall_get_trace): avoid crash if the exception is
142 * exception.c (ves_icall_get_trace): avoid crash on unmanaged frames.
144 2003-01-26 Martin Baulig <martin@ximian.com>
146 * debug.c (mono_debug_init): Take a boolean argument which
147 specifies whether we're running in the Mono Debugger.
149 2003-01-24 Martin Baulig <martin@ximian.com>
151 * debug.c (mono_debug_io_layer): Disable this on Windows.
153 2003-01-23 Dick Porter <dick@ximian.com>
155 * mono.c: Use mono_runtime_exec_managed_code() to run all managed
158 * jit.c: Changed thread start and attach callbacks to pass the
159 thread ID, not the MonoThread pointer. Arrange that managed code
160 execution will fail an assertion in the main thread, just to be
163 2003-01-22 Martin Baulig <martin@ximian.com>
165 * debug.c: Reverted Gonzalo's last change since it is wrong.
166 We're also using the debugging code on Windows, for instance the
167 stabs stuff when running in gdb. I hope this code still builds on
168 Windows; if not, we need to fix this.
169 Moved all the mono debugger support code into the debugger itself;
170 when debugging a managed application, the debugger new launches a
171 small unmanaged wrapper application which contains this stuff.
173 * debug.h (MonoDebuggerIOLayer): New public typedef; this is just
174 initialized to an array of function pointers to the io-layer
175 function; they don't seem to be public in the `libmono' library.
176 (mono_debugger_event): New public function. Sends the debugger an
177 event if we're running in the Mono Debugger and does nothing otherwise.
179 * mono.c: Don't initialize the Mono Debugger here.
181 * jit.c (mono_debug_insert_breakpoint): Removed, this isn't used anymore.
182 (mono_thread_start_cb, mono_thread_attach_cb): Call
183 mono_debugger_event() to send the debugger a callback.
185 2003-01-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
187 * debug.c: make all public symbols just dummy for windows.
189 2003-01-20 Miguel de Icaza <miguel@ximian.com>
191 * debug.c (initialize_debugger_support): ifdef out the call to
192 mono_debugger_init_thread_debug for the release.
194 Someone should look into why its not defined. I think the problem
195 is what Dick pointed out somewhere: code in io-layer is not
196 supposed to ever be used in Windows, so code for the debugger that
197 lives there must be moved elsewhere.
199 2003-01-19 Martin Baulig <martin@ximian.com>
201 * debug.c: Ok, this should now finally be working this time ....
203 2003-01-18 Martin Baulig <martin@ximian.com>
205 * debug.c (mono_debugger_jit_exec): Send the background thread a
206 SIGKILL before returning.
208 2003-01-17 Dietmar Maurer <dietmar@ximian.com>
210 * x86.brg: removed duplicated CONV_OVF_I4
212 2003-01-17 Martin Baulig <martin@ximian.com>
214 * debug.c: Don't use mono_once here. Reworked the API a bit to
215 use `mono_debug_' and `debug_' for the general debugging API and
216 `mono_debugger_' and `debugger_' for the Mono Debugger stuff.
218 2003-01-16 Martin Baulig <martin@ximian.com>
220 * debug.c (debugger_thread_func): We don't need to `raise
221 (SIGSTOP)' anymore; the thread manager already takes care of this.
223 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
225 * exception.c (arch_handle_exception): exclude runtime invoke
226 wrapper from the stack trace
228 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
229 (mono_thread_start_cb): save an additional LMF at thread start
231 2003-01-16 Martin Baulig <martin@ximian.com>
233 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
234 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
235 and the LinuxThreads port doesn't allow you to override the handler.
236 [FIXME: This avoids an assertion failure on startup, but there's
237 still an issue with thread termination.]
239 2003-01-16 Martin Baulig <martin@ximian.com>
241 * debug.c (debugger_thread_func): We don't need to `raise
242 (SIGSTOP)' anymore; the thread manager already takes care of this.
244 2003-01-16 Martin Baulig <martin@ximian.com>
246 * debug.c: Use the mono/io-layer functions here instead of gthread.
248 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
250 * jit.c (mono_jit_compile_method): make sure runtime_init is called
251 (mono_analyze_stack): make sure runtime_init is called
253 2003-01-14 Martin Baulig <martin@ximian.com>
255 * debug.c (debugger_update_symbol_file_table): Moved all the
256 functionality into debugger_update_symbol_file_table_internal();
257 the latter one will be called from the background thread while
258 already owning the lock. This'll allow us to step into
259 debugger_update_symbol_file_table() in the debugger and debug it.
261 2003-01-14 Martin Baulig <martin@ximian.com>
263 * Makefile.am: Link against gthread.
265 * jit.c: After realizing that mono-mutex doesn't work either
266 because it doesn't support recursive mutexes on FreeBSD, rewrote
267 the whole thread stuff to use gthread. This seems to fix this
268 weird deadlock in the debugger as well.
270 2003-01-12 Alp Toker <alp@atoker.com>
272 * exception.c: Typo fix: insinde -> inside
274 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
276 * exception.c (ves_icall_get_frame_info): skip one more frame and also
277 MONO_WRAPPER_RUNTIME_INVOKE wrappers
278 (x86_unwind_native_frame): disable unnecessary assertion
280 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
282 * exception.c (ves_icall_get_frame_info): fix bug 36382
284 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
286 * jit.c: handle wrapper_data in NEWOBJ/CALL.
288 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
290 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
292 2003-01-06 Martin Baulig <martin@ximian.com>
294 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
296 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
297 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
299 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
301 * debug.c: Move must_send_finished var declaration out of #if win32
302 block (this fixes the build on win32)
304 2003-01-05 Martin Baulig <martin@ximian.com>
306 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
307 this is used when we're running inside the Mono Debugger
308 (mono_debugger_wait): Put the waiting code into a function of its own.
310 * mono.c (main): Call mono_debugger_jit_exec() instead of
311 mono_jit_exec() if we're running inside the Mono Debugger.
313 2003-01-05 Martin Baulig <martin@ximian.com>
315 * debug.h (MonoDebugFormat): Added
316 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
317 we're running inside the Mono Debugger prior to the args parsing.
319 2003-01-04 Martin Baulig <martin@ximian.com>
321 * debug.c (release_symbol_file_table): Only call this if we're
322 actually modifying the symbol tables.
323 (mono_debug_open): Always set the `mono_debugger_class_init_func'
324 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
326 2003-01-03 Martin Baulig <martin@ximian.com>
328 * debug.c: Disable the mono debugger stuff on Windows.
330 2003-01-03 Martin Baulig <martin@ximian.com>
332 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
333 function. This is called from the breakpoint trampoline to signal
334 the debugger and wait until it has reload the symbol tables.
336 * trampoline.c (get_breakpoint_trampoline): Call the new
337 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
338 trampoline just before the breakpoint.
340 2002-12-31 Martin Baulig <martin@ximian.com>
342 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
343 field to point to the MonoGlobalSymbolTable.
345 2002-12-30 Martin Baulig <martin@ximian.com>
347 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
348 This variable now specifies that the symbol tables have been
349 modified after the last notification has been send. The debugger
350 uses this flag to check whether it needs to reload the symbol
352 (debugger_compile_method): Just send a notification to the
353 debugger, but don't set the modified flag. It may or may not be
354 set when the debugger gets the notification - depending on whether
355 the JIT compilation added a new method to the symbol tables.
357 2002-12-30 Martin Baulig <martin@ximian.com>
359 * debug.c (debugger_compile_method): This is a wrapper around
360 mono_compile_method() which always sends a notification to the
363 2002-12-30 Martin Baulig <martin@ximian.com>
365 * debug.c: Reload the symbol file table before sending the
366 notification event to the debugger.
367 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
369 2002-12-31 Martin Baulig <martin@ximian.com>
371 * debug.c: Propertly lock everything and avoid race conditions.
372 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
374 2002-12-31 Duncan Mak <duncan@ximian.com>
376 * debug.c (initialize_debugger_support): Fix build error by
377 declaring ret at the top of the function.
379 2002-12-30 Martin Baulig <martin@ximian.com>
381 * debug.c: When running under the mono debugger, create a special
382 debugger thread; always protect the symbol tables with a mutex.
384 2002-12-28 Martin Baulig <martin@ximian.com>
386 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
387 incremented each time one of the symbol tables is modified.
389 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
391 * jit.c: fix LDELEMA implementation here as well.
393 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
395 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
397 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
399 * jit.c: query the thread abort signal from the runtime.
401 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
403 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
405 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
407 * jit.c (mono_analyze_stack): call the utility function
408 mono_field_from_token to avoid code duplication.
410 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
412 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
414 * x86.brg (stmt): POP floating point stack correctly
416 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
418 * emit-x86.c (arch_emit_prologue): don't save caller saved
421 * exception.c (x86_unwind_native_frame): support exceptions inside
422 native code using gcc generated exception tables (-fexception).
424 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
426 * exception.c: include some code from Zoltan Varga, but modified
429 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
431 * exception.c: massive code cleanups. The code is still
432 architecture dependent, but it should be now possible to reuse the
433 complex parts for other architecture.
435 2002-11-15 Dick Porter <dick@ximian.com>
437 * jit.c: Pass the attach callback to mono_runtime_init().
439 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
441 * jit.c: display the domain name in trace output.
443 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
445 * x86.brg (reg): fix bug #2721
447 * jit.c (mono_runtime_install_handlers): impl.
449 2002-10-17 Martin Baulig <martin@gnome.org>
451 * debug.c (mono_debug_add_method): Make this actually work if we don't
452 have any lifetime information.
454 2002-10-15 Martin Baulig <martin@gnome.org>
456 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
458 * debug.c (generate_line_number): Small fix to make this actually
459 work for more complex things.
461 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
463 * x86.brg (freg): use fprem instead of fprem1
465 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
467 * jit.c (ves_array_element_address): added check for out of range index
468 (mono_analyze_stack): added fix for bug #31654
470 2002-10-01 Martin Baulig <martin@gnome.org>
472 * debug.c: Don't create an .il file for the dynamic symbol file.
474 2002-10-01 Martin Baulig <martin@gnome.org>
476 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
478 2002-09-27 Martin Baulig <martin@gnome.org>
480 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
482 2002-09-27 Dick Porter <dick@ximian.com>
484 * mono.c: Tell glib what the program name is, by passing it the
485 name of the managed file we're executing
487 2002-09-26 Martin Baulig <martin@gnome.org>
489 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
490 trampoline into the vtable, also use it for non-virtual methods,
491 remove the breakpoint when done.
493 2002-09-26 Martin Baulig <martin@gnome.org>
495 * debug.c (debug_load_method_lines): Block SIGCHLD while running
498 2002-09-26 Martin Baulig <martin@gnome.org>
500 * debug.c: Reworked the whole debugging stuff. We have now one
501 single `mono_debug_handle' which keeps a hashtable of
502 `AssemblyDebugInfo's (which may have different debugging formats).
503 The AssemblyDebugInfo is now created when the assembly is loaded,
504 but never when adding a class/type.
506 * mono.c: Initialize debugging stuff after corlib and the assembly
509 2002-09-25 Martin Baulig <martin@gnome.org>
511 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
512 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
514 (DebugMethodInfo): Removed `line_numbers'.
516 * debug.c: Reworked the line number generation; we're now using
517 the MonoDebugLineNumberEntry try for all debugging formats. This
518 type also includes the line number and IL offset, this allows the
519 JIT to produce better line number info: we only emit line number
520 information for source lines which actually have code.
522 2002-09-25 Martin Baulig <martin@gnome.org>
524 * debug.h: Removed external declaration of all functions which
525 should only be called from the Mono Debugger and also made them
526 static. Since the debugger gets their address from the
527 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
530 2002-09-25 Martin Baulig <martin@gnome.org>
532 Improved breakpoint support, we can now dynamically insert and
533 remove breakpoints at runtime and when called from withing the
534 Mono Debugger, we're using a special breakpoint trampoline.
536 * debug.h (mono_method_has_breakpoint): New method to check
537 whether to insert a breakpoint for a method.
538 (mono_insert_breakpoint): New method to insert a breakpoint.
539 (mono_insert_breakpoint_full): New method to insert a breakpoint,
540 takes a MonoMethodDesc.
541 (mono_remove_breakpoint): New method to remove a breakpoint.
543 * debug.c (mono_debugger_insert_breakpoint): New function for the
544 debugger. Should only be called from the debugger.
545 (mono_debugger_remove_breakpoint): Likewise.
547 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
549 * trampoline.c (get_breakpoint_trampoline): New static function to
550 create a special breakpoint trampoline for the debugger.
551 (x86_magic_trampoline): If we're running inside the Mono Debugger
552 and a breakpoint was requested for the method, generate a special
553 breakpoint trampoline.
555 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
556 to insert a breakpoint.
557 (mono_debug_last_breakpoint_address): Removed.
558 (match_debug_method): Removed, use mono_method_has_breakpoint().
560 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
562 * jit.c: reorder mono_runtime_cleanup () call since it needs the
563 engine still fully working.
565 2002-09-24 Martin Baulig <martin@gnome.org>
567 * debug.c (mono_debug_open): When we're invoked from inside the
568 Mono Debugger, set mono_debugger_class_init_func (exported in
569 metadata/class.c) to mono_add_type().
570 (mono_add_type): Call mono_debug_symfile_add_type().
572 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
574 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
575 Run finalize on domain cleanup.
576 * mono.c: call setlocale ().
577 * trampoline.c: clearer error message for invalid trampoline.
579 2002-09-21 Martin Baulig <martin@gnome.org>
581 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
582 instead of writing a byte blob.

646 file name argument; you can now call this before loading the assembly.
647 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
648 we now use MonoSymbolFileLineNumberEntry's and a separate address array
649 instead; splitted out all MonoSymbolFileLineNumberEntry code into
650 debug_generate_il_offsets() and debug_update_il_offsets().

1187 a `MonoAssembly *' argument instead of a `char *filename' one. Also added
1188 `const char **args' argument.
1190 * mono.c (mono_jit_assembly): Renamed to mono_jit_compile_image(), added
1191 `int verbose' argument and made it public.
1192 (mono_jit_compile_class): New public function, moved the code to compile
1193 all methods in a class here from main().
1194 (--compile): The argument can now also be an image (in `@imagename' format).
1195 Updated documentation for this command line argument.
1196 (--precompile): New command line argument to precompile an image/class/method
1197 before executing the main app. This argument can be given multiple times.

1231 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
1232 file for all assemblies. Currently, the JIT doesn't put all methods
1233 from a single assembly into a continuous region of memory. We were
1234 previously creating valid DWARF 2 files for this, but unfortunately
1235 GDB's symbol tables get messed up when it reads more than one such file.
1237 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',
1238 `next_idx', `methods', `type_hash', `source_files' and `format'
1239 into the MonoDebugHandle.

1252 (mono_debug_open_assembly_stabs): Removed.
1253 (mono_debug_close_assembly_stabs).
1255 * debug-dwarf2-plus.c: This is currently broken. :-(

1331 SHL/SHR because the tree allocator can fail otherwise
1333 * exception.c (arch_handle_exception): EIP now points to the call
1334 instruction, not to the instruction after the call. This fixes the
1335 bug reported by Linus Upson (tests/exception8.cs)

1783 2002-03-23 Martin Baulig <martin@gnome.org>
1785 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1786 to do it before the X86_CMP.
1787 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1788 (reg: CLT (lreg, lreg)): Likewise.

1902 (mono_debug_open_file): Added MonoDebugFormat argument.
1903 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1904 this function from GDB. It's now safe to call this function multiple times;
1905 it'll always write a complete debugging file.
1907 * debug.c: Splitted this file into a general part which remains in this file
1908 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1909 All public functions now call a corresponding format specific function.
1911 * debug.c: The following changes are private to debug.c:
1912 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1913 (record_line_number, debug_generate_method_lines): New private functions.
1914 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1915 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1916 mono_debug_open_assembly_dwarf2).
1917 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1918 now safe to call this function multiple times.
1919 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1920 returns an unique index for this type. It's used to ensure that we only write
1921 each class once to the debugging file.
1922 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1923 data structure, but don't directly write to the debugging file. This is done
1924 later from mono_debug_write_assembly().
1926 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1927 debugging output. Call mono_debug_close() on cleanup if necessary.

1931 * debug-private.h: New private header file.
1933 * debug-stabs.c: Added the stabs type generation stuff which was
1934 previously in debug.c.

1937 only writing this most basic types to the dwarf file, but this will
1940 2002-03-13 Martin Baulig <martin@gnome.org>
1942 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1943 debugging code. They're now in CVS, but not yet used anywhere.
1945 2002-03-11 Dietmar Maurer <dietmar@ximian.com>

1953 * jit.c: verify that corlib and runtime are in sync.
1955 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1957 * emit-x86.c, jit.c: use the debug-helpers facilities to
1958 describe and match a method when debugging.
1960 2002-03-10 Martin Baulig <martin@gnome.org>
1962 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1963 output, put a nop instruction at the start of all functions so that
1964 the adresses won't change when using --debug.
1966 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1967 the bytecode area, stabs needs a line number in the .il file. Use the
1968 new info->moffsets to get the line number.
1969 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1970 `moffsets' is an array of `total_lines' fields (total number of lines
1971 in the .il file); for each line in the .il field, this array contains
1972 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1973 of a method and 0 otherwise.
1974 (debug_load_method_lines): Read the whole .il file and initialize the
1975 info->moffsets field.
1977 2002-03-09 Martin Baulig <martin@gnome.org>
1979 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1980 the unnecessary CDQ instruction.
