3 * jit.c: Remove definition of metadata_section mutex from here
5 2003-05-19 Dick Porter <dick@ximian.com>
7 * jit.c: Netbsd build fix by marc@informatik.uni-bremen.de.
9 Thu Apr 24 17:11:03 CEST 2003 Paolo Molaro <lupus@ximian.com>
11 * Makefile.am: rename mono and libmono to oldmono and liboldmono.
13 2003-04-23 Martin Baulig <martin@ximian.com>
15 * mono.c: The `--debug' command line argument doesn't take any
16 arguments anymore, removed the `--debug-args' argument.
18 * debug-jit.c (mono_debug_add_method): Renamed this to
19 mono_debug_jit_add_method(); create the JIT-specific data
20 structure and pass it to mono_debug_add_method().
22 * debug.[ch]: Removed. The code is now in
23 ../metadata/mono-debug.[ch] and mono-debug-debugger.[ch].
25 * debug-stabs.c, debug-dwarf2.c: Removed; nobody used this for the
28 2003-04-21 Martin Baulig <martin@ximian.com>
30 * debug.c (mono_debug_open): Splitted into mono_debug_init() and
32 (mono_debug_open_image): Don't open referenced assemblies; this is
33 done automatically by the code in assembly.c.
35 * mono.c (main_thread_handler): Call mono_debug_init() before
36 opening the assembly because we need to install the assembly load
39 2003-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
42 (mono_jit_cleanup): moved mono_runtime_cleanup call after the call to
45 2003-04-05 Miguel de Icaza <miguel@ximian.com>
47 * jit.c (check_inlining): honor the NOINLING atttribute.
49 2003-03-31 Martin Baulig <martin@ximian.com>
51 * debug.h (MonoDebuggerEvent): Removed
52 MONO_DEBUGGER_EVENT_THREAD_CREATED.
54 * jit.c (mono_thread_start_cb): Don't send the
55 MONO_DEBUGGER_EVENT_THREAD_CREATED event.
57 2003-03-13 Martin Baulig <martin@ximian.com>
59 * debug.c (_mono_debug_address_from_il_offset): Moved to
60 ../metadata/debug-mono-symfile.c
62 2003-03-07 Martin Baulig <martin@ximian.com>
64 * debug-jit.c: #include <config.h>.
66 2003-03-05 Martin Baulig <martin@ximian.com>
68 * debug-jit.c, debug-jit.h: New files. Moved all JIT-specific
71 * debug.c (mono_debug_add_method): Moved to debug-jit.c.
72 (mono_debug_handle, mono_debug_initialized): Made them global.
73 (replace_suffix): Removed, this isn't used anymore.
74 (record_line_number): Moved to debug-jit.c.
75 (debug_generate_method_lines): Moved to debug-jit.c
76 (generate_line_number): Renamed to
77 _mono_debug_generate_line_number() and made it global.
78 (debug_update_il_offsets): Moved to debug-jit.c
79 (mono_debug_get_image): Renamed to _mono_debug_get_image() and made
81 (address_from_il_offset): Renamed to
82 _mono_debug_address_from_il_offset() and made it global.
83 (il_offset_from_position): Moved to debug-jit.c
84 (lookup_method): Renamed to _mono_debug_lookup_method() and made
86 (mono_debug_add_method): Moved to debug-jit.c.
87 (mono_debug_create_notification_function): Use two new functions
88 mono_debug_codegen_breakpoint() and mono_debug_codegen_ret()
89 instead of x86_breakpoint() and x86_ret().
91 Sat Mar 1 12:36:45 CET 2003 Paolo Molaro <lupus@ximian.com>
93 * jit.c: remove unnecessary assert when inlining.
95 2003-02-17 Martin Baulig <martin@ximian.com>
97 * jit.c (mono_jit_compile_method): Don't emit a `nop' at the start
100 2003-02-14 Patrik Torstensson
102 * x86.brg: Implemented CONV_OVF_[I|U]4 (freg), this fixes the issues
103 with the "checked" keyword. Closes bugs #33421 and #35280 (JIT not mint)
105 2003-02-14 Dietmar Maurer <dietmar@ximian.com>
107 * exception.c (mono_arch_find_jit_info): better way to handle
108 situations where we have no MonoJitInfo
110 2003-02-11 Zoltan Varga <vargaz@freemail.hu>
112 * trampoline.c (arch_create_jit_trampoline): This function should
113 allways return a trampoline for managed methods. Fixes bug #29859.
115 2003-02-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
117 * debug.c: allocate debug->source_files. Fixes GLib-CRITICAL upon
120 2003-02-02 Martin Baulig <martin@ximian.com>
122 * debug.c (mono_debug_add_wrapper): Lookup the wrapper method in a
123 hash table; we need to provide the correct code_size.
125 2003-02-02 Martin Baulig <martin@ximian.com>
127 * jit.c (mono_jit_compile_method): Call mono_debug_add_wrapper()
128 to add the interncall to the symbol file.
130 * debug.c (mono_debug_add_wrapper): New public function.
132 2003-02-02 Martin Baulig <martin@ximian.com>
134 * debug.c (debug_update_il_offsets): Set the prologue end address
135 to the address of the first source line.
137 2003-01-31 Dietmar Maurer <dietmar@ximian.com>
139 * jit.c (mono_analyze_stack): use the wrapper signature if necessary
141 2003-01-31 Zoltan Varga <vargaz@freemail.hu>
143 * debug.c (mono_debug_open_image): dynamic assemblies have no debug
146 Thu Jan 30 11:07:06 CET 2003 Paolo Molaro <lupus@ximian.com>
148 * helper.c: handle MONO_TYPE_ARRAY as well.
150 2003-01-29 Dietmar Maurer <dietmar@ximian.com>
152 * jit.c (mono_analyze_stack): impl. CEE_MONO_LDNATIVEOBJ
153 (mono_analyze_stack): RETOBJ always returns native sized objects
155 2003-01-28 Zoltan Varga <vargaz@freemail.hu>
157 * x86.brg (mono_ldintftn): use <= instead of <, since the
158 interface_offsets array is max_interface_id + 1 long.
160 2003-01-28 Dietmar Maurer <dietmar@ximian.com>
162 * x86.brg (mono_ldintftn): fix from Zoltan: use max_interface_id
164 2003-01-27 Zoltan Varga <vargaz@freemail.hu>
166 * exception.c (ves_icall_get_trace): avoid crash if the exception is
169 * exception.c (ves_icall_get_trace): avoid crash on unmanaged frames.
171 2003-01-26 Martin Baulig <martin@ximian.com>
173 * debug.c (mono_debug_init): Take a boolean argument which
174 specifies whether we're running in the Mono Debugger.
176 2003-01-24 Martin Baulig <martin@ximian.com>
178 * debug.c (mono_debug_io_layer): Disable this on Windows.
180 2003-01-23 Dick Porter <dick@ximian.com>
182 * mono.c: Use mono_runtime_exec_managed_code() to run all managed
185 * jit.c: Changed thread start and attach callbacks to pass the
186 thread ID, not the MonoThread pointer. Arrange that managed code
187 execution will fail an assertion in the main thread, just to be
190 2003-01-22 Martin Baulig <martin@ximian.com>
192 * debug.c: Reverted Gonzalo's last change since it is wrong.
193 We're also using the debugging code on Windows, for instance the
194 stabs stuff when running in gdb. I hope this code still builds on
195 Windows; if not, we need to fix this.
196 Moved all the mono debugger support code into the debugger itself;
197 when debugging a managed application, the debugger new launches a
198 small unmanaged wrapper application which contains this stuff.
200 * debug.h (MonoDebuggerIOLayer): New public typedef; this is just
201 initialized to an array of function pointers to the io-layer
202 function; they don't seem to be public in the `libmono' library.
203 (mono_debugger_event): New public function. Sends the debugger an
204 event if we're running in the Mono Debugger and does nothing otherwise.
206 * mono.c: Don't initialize the Mono Debugger here.
208 * jit.c (mono_debug_insert_breakpoint): Removed, this isn't used anymore.
209 (mono_thread_start_cb, mono_thread_attach_cb): Call
210 mono_debugger_event() to send the debugger a callback.
212 2003-01-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
214 * debug.c: make all public symbols just dummy for windows.
216 2003-01-20 Miguel de Icaza <miguel@ximian.com>
218 * debug.c (initialize_debugger_support): ifdef out the call to
219 mono_debugger_init_thread_debug for the release.
221 Someone should look into why its not defined. I think the problem
222 is what Dick pointed out somewhere: code in io-layer is not
223 supposed to ever be used in Windows, so code for the debugger that
224 lives there must be moved elsewhere.
226 2003-01-19 Martin Baulig <martin@ximian.com>
228 * debug.c: Ok, this should now finally be working this time ....
230 2003-01-18 Martin Baulig <martin@ximian.com>
232 * debug.c (mono_debugger_jit_exec): Send the background thread a
233 SIGKILL before returning.
235 2003-01-17 Dietmar Maurer <dietmar@ximian.com>
237 * x86.brg: removed duplicated CONV_OVF_I4
239 2003-01-17 Martin Baulig <martin@ximian.com>
241 * debug.c: Don't use mono_once here. Reworked the API a bit to
242 use `mono_debug_' and `debug_' for the general debugging API and
243 `mono_debugger_' and `debugger_' for the Mono Debugger stuff.
245 2003-01-16 Martin Baulig <martin@ximian.com>
247 * debug.c (debugger_thread_func): We don't need to `raise
248 (SIGSTOP)' anymore; the thread manager already takes care of this.
250 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
252 * exception.c (arch_handle_exception): exclude runtime invoke
253 wrapper from the stack trace
255 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
256 (mono_thread_start_cb): save an additional LMF at thread start
258 2003-01-16 Martin Baulig <martin@ximian.com>
260 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
261 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
262 and the LinuxThreads port doesn't allow you to override the handler.
263 [FIXME: This avoids an assertion failure on startup, but there's
264 still an issue with thread termination.]
266 2003-01-16 Martin Baulig <martin@ximian.com>
268 * debug.c (debugger_thread_func): We don't need to `raise
269 (SIGSTOP)' anymore; the thread manager already takes care of this.
271 2003-01-16 Martin Baulig <martin@ximian.com>
273 * debug.c: Use the mono/io-layer functions here instead of gthread.
275 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
277 * jit.c (mono_jit_compile_method): make sure runtime_init is called
278 (mono_analyze_stack): make sure runtime_init is called
280 2003-01-14 Martin Baulig <martin@ximian.com>
282 * debug.c (debugger_update_symbol_file_table): Moved all the
283 functionality into debugger_update_symbol_file_table_internal();
284 the latter one will be called from the background thread while
285 already owning the lock. This'll allow us to step into
286 debugger_update_symbol_file_table() in the debugger and debug it.
288 2003-01-14 Martin Baulig <martin@ximian.com>
290 * Makefile.am: Link against gthread.
292 * jit.c: After realizing that mono-mutex doesn't work either
293 because it doesn't support recursive mutexes on FreeBSD, rewrote
294 the whole thread stuff to use gthread. This seems to fix this
295 weird deadlock in the debugger as well.
297 2003-01-12 Alp Toker <alp@atoker.com>
299 * exception.c: Typo fix: insinde -> inside
301 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
303 * exception.c (ves_icall_get_frame_info): skip one more frame and also
304 MONO_WRAPPER_RUNTIME_INVOKE wrappers
305 (x86_unwind_native_frame): disable unnecessary assertion
307 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
309 * exception.c (ves_icall_get_frame_info): fix bug 36382
311 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
313 * jit.c: handle wrapper_data in NEWOBJ/CALL.
315 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
317 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
319 2003-01-06 Martin Baulig <martin@ximian.com>
321 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
323 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
324 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
326 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
328 * debug.c: Move must_send_finished var declaration out of #if win32
329 block (this fixes the build on win32)
331 2003-01-05 Martin Baulig <martin@ximian.com>
333 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
334 this is used when we're running inside the Mono Debugger
335 (mono_debugger_wait): Put the waiting code into a function of its own.
337 * mono.c (main): Call mono_debugger_jit_exec() instead of
338 mono_jit_exec() if we're running inside the Mono Debugger.
340 2003-01-05 Martin Baulig <martin@ximian.com>
342 * debug.h (MonoDebugFormat): Added
343 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
344 we're running inside the Mono Debugger prior to the args parsing.
346 2003-01-04 Martin Baulig <martin@ximian.com>
348 * debug.c (release_symbol_file_table): Only call this if we're
349 actually modifying the symbol tables.
350 (mono_debug_open): Always set the `mono_debugger_class_init_func'
351 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
353 2003-01-03 Martin Baulig <martin@ximian.com>
355 * debug.c: Disable the mono debugger stuff on Windows.
357 2003-01-03 Martin Baulig <martin@ximian.com>
359 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
360 function. This is called from the breakpoint trampoline to signal
361 the debugger and wait until it has reload the symbol tables.
363 * trampoline.c (get_breakpoint_trampoline): Call the new
364 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
365 trampoline just before the breakpoint.
367 2002-12-31 Martin Baulig <martin@ximian.com>
369 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
370 field to point to the MonoGlobalSymbolTable.
372 2002-12-30 Martin Baulig <martin@ximian.com>
374 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
375 This variable now specifies that the symbol tables have been
376 modified after the last notification has been send. The debugger
377 uses this flag to check whether it needs to reload the symbol
379 (debugger_compile_method): Just send a notification to the
380 debugger, but don't set the modified flag. It may or may not be
381 set when the debugger gets the notification - depending on whether
382 the JIT compilation added a new method to the symbol tables.
384 2002-12-30 Martin Baulig <martin@ximian.com>
386 * debug.c (debugger_compile_method): This is a wrapper around
387 mono_compile_method() which always sends a notification to the
390 2002-12-30 Martin Baulig <martin@ximian.com>
392 * debug.c: Reload the symbol file table before sending the
393 notification event to the debugger.
394 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
396 2002-12-31 Martin Baulig <martin@ximian.com>
398 * debug.c: Propertly lock everything and avoid race conditions.
399 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
401 2002-12-31 Duncan Mak <duncan@ximian.com>
403 * debug.c (initialize_debugger_support): Fix build error by
404 declaring ret at the top of the function.
406 2002-12-30 Martin Baulig <martin@ximian.com>
408 * debug.c: When running under the mono debugger, create a special
409 debugger thread; always protect the symbol tables with a mutex.
411 2002-12-28 Martin Baulig <martin@ximian.com>
413 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
414 incremented each time one of the symbol tables is modified.
416 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
418 * jit.c: fix LDELEMA implementation here as well.
420 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
422 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
424 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
426 * jit.c: query the thread abort signal from the runtime.
428 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
430 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
432 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
434 * jit.c (mono_analyze_stack): call the utility function
435 mono_field_from_token to avoid code duplication.
437 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
439 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
441 * x86.brg (stmt): POP floating point stack correctly
443 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
445 * emit-x86.c (arch_emit_prologue): don't save caller saved
448 * exception.c (x86_unwind_native_frame): support exceptions inside
449 native code using gcc generated exception tables (-fexception).
451 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
453 * exception.c: include some code from Zoltan Varga, but modified
456 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
458 * exception.c: massive code cleanups. The code is still
459 architecture dependent, but it should be now possible to reuse the
460 complex parts for other architecture.
462 2002-11-15 Dick Porter <dick@ximian.com>
464 * jit.c: Pass the attach callback to mono_runtime_init().
466 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
468 * jit.c: display the domain name in trace output.
470 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
472 * x86.brg (reg): fix bug #2721
474 * jit.c (mono_runtime_install_handlers): impl.
476 2002-10-17 Martin Baulig <martin@gnome.org>
478 * debug.c (mono_debug_add_method): Make this actually work if we don't
479 have any lifetime information.
481 2002-10-15 Martin Baulig <martin@gnome.org>
483 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
485 * debug.c (generate_line_number): Small fix to make this actually
486 work for more complex things.
488 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
490 * x86.brg (freg): use fprem instead of fprem1
492 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
494 * jit.c (ves_array_element_address): added check for out of range index
495 (mono_analyze_stack): added fix for bug #31654
497 2002-10-01 Martin Baulig <martin@gnome.org>
499 * debug.c: Don't create an .il file for the dynamic symbol file.
501 2002-10-01 Martin Baulig <martin@gnome.org>
503 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
505 2002-09-27 Martin Baulig <martin@gnome.org>
507 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
509 2002-09-27 Dick Porter <dick@ximian.com>
511 * mono.c: Tell glib what the program name is, by passing it the
512 name of the managed file we're executing
514 2002-09-26 Martin Baulig <martin@gnome.org>
516 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
517 trampoline into the vtable, also use it for non-virtual methods,
518 remove the breakpoint when done.
520 2002-09-26 Martin Baulig <martin@gnome.org>
522 * debug.c (debug_load_method_lines): Block SIGCHLD while running
525 2002-09-26 Martin Baulig <martin@gnome.org>
527 * debug.c: Reworked the whole debugging stuff. We have now one
528 single `mono_debug_handle' which keeps a hashtable of
529 `AssemblyDebugInfo's (which may have different debugging formats).
530 The AssemblyDebugInfo is now created when the assembly is loaded,
531 but never when adding a class/type.
533 * mono.c: Initialize debugging stuff after corlib and the assembly
536 2002-09-25 Martin Baulig <martin@gnome.org>
538 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
539 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
541 (DebugMethodInfo): Removed `line_numbers'.
543 * debug.c: Reworked the line number generation; we're now using
544 the MonoDebugLineNumberEntry try for all debugging formats. This
545 type also includes the line number and IL offset, this allows the
546 JIT to produce better line number info: we only emit line number
547 information for source lines which actually have code.
549 2002-09-25 Martin Baulig <martin@gnome.org>
551 * debug.h: Removed external declaration of all functions which
552 should only be called from the Mono Debugger and also made them
553 static. Since the debugger gets their address from the
554 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
557 2002-09-25 Martin Baulig <martin@gnome.org>
559 Improved breakpoint support, we can now dynamically insert and
560 remove breakpoints at runtime and when called from withing the
561 Mono Debugger, we're using a special breakpoint trampoline.
563 * debug.h (mono_method_has_breakpoint): New method to check
564 whether to insert a breakpoint for a method.
565 (mono_insert_breakpoint): New method to insert a breakpoint.
566 (mono_insert_breakpoint_full): New method to insert a breakpoint,
567 takes a MonoMethodDesc.
568 (mono_remove_breakpoint): New method to remove a breakpoint.
570 * debug.c (mono_debugger_insert_breakpoint): New function for the
571 debugger. Should only be called from the debugger.
572 (mono_debugger_remove_breakpoint): Likewise.
574 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
576 * trampoline.c (get_breakpoint_trampoline): New static function to
577 create a special breakpoint trampoline for the debugger.
578 (x86_magic_trampoline): If we're running inside the Mono Debugger
579 and a breakpoint was requested for the method, generate a special
580 breakpoint trampoline.
582 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
583 to insert a breakpoint.
584 (mono_debug_last_breakpoint_address): Removed.
585 (match_debug_method): Removed, use mono_method_has_breakpoint().

590 engine still fully working.
592 2002-09-24 Martin Baulig <martin@gnome.org>
594 * debug.c (mono_debug_open): When we're invoked from inside the

596 metadata/class.c) to mono_add_type().
597 (mono_add_type): Call mono_debug_symfile_add_type().
599 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>

669 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
670 `mono_symfile' to `symfile'.
672 * debug.c (mono_debug_open): Replaced the assembly argument with a
673 file name argument; you can now call this before loading the assembly.
674 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
675 we now use MonoSymbolFileLineNumberEntry's and a separate address array
676 instead; splitted out all MonoSymbolFileLineNumberEntry code into
677 debug_generate_il_offsets() and debug_update_il_offsets().
678 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
679 created when reading the symbol file or from debug_load_method_lines().

729 AssemblyDebugInfo struct since we need to use a separate hash for each
732 * debug.c: Added special undocumented command line argument to create a
733 symbol file for IL files on-the-fly. In this case, we also need to create
734 the IL files and parse them.

779 * x86.brg (mono_llmult_ovf): Simplified the code greatly by refactoring
780 the algebraic form we are using. This also eliminated a silly overflow
781 of the intermediate result that was causing troubles.
783 2002-08-16 Nick Drochak <ndrochak@gol.com>
785 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers

810 versions of linuxthreads.
812 * jit.c (mono_runtime_install_handlers): switch back to use

1215 `const char **args' argument.
1217 * mono.c (mono_jit_assembly): Renamed to mono_jit_compile_image(), added
1218 `int verbose' argument and made it public.
1219 (mono_jit_compile_class): New public function, moved the code to compile
1220 all methods in a class here from main().

1258 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
1259 file for all assemblies. Currently, the JIT doesn't put all methods
1260 from a single assembly into a continuous region of memory. We were
1261 previously creating valid DWARF 2 files for this, but unfortunately
1262 GDB's symbol tables get messed up when it reads more than one such file.
1264 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

1358 SHL/SHR because the tree allocator can fail otherwise
1360 * exception.c (arch_handle_exception): EIP now points to the call
1361 instruction, not to the instruction after the call. This fixes the
1362 bug reported by Linus Upson (tests/exception8.cs)

1810 2002-03-23 Martin Baulig <martin@gnome.org>
1812 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1813 to do it before the X86_CMP.
1814 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1815 (reg: CLT (lreg, lreg)): Likewise.

1929 (mono_debug_open_file): Added MonoDebugFormat argument.
1930 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1931 this function from GDB. It's now safe to call this function multiple times;
1932 it'll always write a complete debugging file.
1934 * debug.c: Splitted this file into a general part which remains in this file
1935 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1936 All public functions now call a corresponding format specific function.
1938 * debug.c: The following changes are private to debug.c:
1939 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1940 (record_line_number, debug_generate_method_lines): New private functions.
1941 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1942 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1943 mono_debug_open_assembly_dwarf2).
1944 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1945 now safe to call this function multiple times.
1946 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1947 returns an unique index for this type. It's used to ensure that we only write
1948 each class once to the debugging file.
1949 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1950 data structure, but don't directly write to the debugging file. This is done
1951 later from mono_debug_write_assembly().
1953 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1954 debugging output. Call mono_debug_close() on cleanup if necessary.

1958 * debug-private.h: New private header file.
1960 * debug-stabs.c: Added the stabs type generation stuff which was
1961 previously in debug.c.

1964 only writing this most basic types to the dwarf file, but this will
1967 2002-03-13 Martin Baulig <martin@gnome.org>
1969 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1970 debugging code. They're now in CVS, but not yet used anywhere.
1972 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1974 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*

1980 * jit.c: verify that corlib and runtime are in sync.
1982 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1984 * emit-x86.c, jit.c: use the debug-helpers facilities to
1985 describe and match a method when debugging.
1987 2002-03-10 Martin Baulig <martin@gnome.org>
1989 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1990 output, put a nop instruction at the start of all functions so that
1991 the adresses won't change when using --debug.
1993 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1994 the bytecode area, stabs needs a line number in the .il file. Use the
1995 new info->moffsets to get the line number.
1996 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1997 `moffsets' is an array of `total_lines' fields (total number of lines
1998 in the .il file); for each line in the .il field, this array contains
1999 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
2000 of a method and 0 otherwise.
2001 (debug_load_method_lines): Read the whole .il file and initialize the
2002 info->moffsets field.
2004 2002-03-09 Martin Baulig <martin@gnome.org>
2006 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
2007 the unnecessary CDQ instruction.
2009 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
