1 2003-03-05 Martin Baulig <martin@ximian.com>
3 * debug-jit.c, debug-jit.h: New files. Moved all JIT-specific
6 * debug.c (mono_debug_add_method): Moved to debug-jit.c.
7 (mono_debug_handle, mono_debug_initialized): Made them global.
8 (replace_suffix): Removed, this isn't used anymore.
9 (record_line_number): Moved to debug-jit.c.
10 (debug_generate_method_lines): Moved to debug-jit.c
11 (generate_line_number): Renamed to
12 _mono_debug_generate_line_number() and made it global.
13 (debug_update_il_offsets): Moved to debug-jit.c
14 (mono_debug_get_image): Renamed to _mono_debug_get_image() and made
16 (address_from_il_offset): Renamed to
17 _mono_debug_address_from_il_offset() and made it global.
18 (il_offset_from_position): Moved to debug-jit.c
19 (lookup_method): Renamed to _mono_debug_lookup_method() and made
21 (mono_debug_add_method): Moved to debug-jit.c.
22 (mono_debug_create_notification_function): Use two new functions
23 mono_debug_codegen_breakpoint() and mono_debug_codegen_ret()
24 instead of x86_breakpoint() and x86_ret().
26 Sat Mar 1 12:36:45 CET 2003 Paolo Molaro <lupus@ximian.com>
28 * jit.c: remove unnecessary assert when inlining.
30 2003-02-17 Martin Baulig <martin@ximian.com>
32 * jit.c (mono_jit_compile_method): Don't emit a `nop' at the start
35 2003-02-14 Patrik Torstensson
37 * x86.brg: Implemented CONV_OVF_[I|U]4 (freg), this fixes the issues
38 with the "checked" keyword. Closes bugs #33421 and #35280 (JIT not mint)
40 2003-02-14 Dietmar Maurer <dietmar@ximian.com>
42 * exception.c (mono_arch_find_jit_info): better way to handle
43 situations where we have no MonoJitInfo
45 2003-02-11 Zoltan Varga <vargaz@freemail.hu>
47 * trampoline.c (arch_create_jit_trampoline): This function should
48 allways return a trampoline for managed methods. Fixes bug #29859.
50 2003-02-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
52 * debug.c: allocate debug->source_files. Fixes GLib-CRITICAL upon
55 2003-02-02 Martin Baulig <martin@ximian.com>
57 * debug.c (mono_debug_add_wrapper): Lookup the wrapper method in a
58 hash table; we need to provide the correct code_size.
60 2003-02-02 Martin Baulig <martin@ximian.com>
62 * jit.c (mono_jit_compile_method): Call mono_debug_add_wrapper()
63 to add the interncall to the symbol file.
65 * debug.c (mono_debug_add_wrapper): New public function.
67 2003-02-02 Martin Baulig <martin@ximian.com>
69 * debug.c (debug_update_il_offsets): Set the prologue end address
70 to the address of the first source line.
72 2003-01-31 Dietmar Maurer <dietmar@ximian.com>
74 * jit.c (mono_analyze_stack): use the wrapper signature if necessary
76 2003-01-31 Zoltan Varga <vargaz@freemail.hu>
78 * debug.c (mono_debug_open_image): dynamic assemblies have no debug
81 Thu Jan 30 11:07:06 CET 2003 Paolo Molaro <lupus@ximian.com>
83 * helper.c: handle MONO_TYPE_ARRAY as well.
85 2003-01-29 Dietmar Maurer <dietmar@ximian.com>
87 * jit.c (mono_analyze_stack): impl. CEE_MONO_LDNATIVEOBJ
88 (mono_analyze_stack): RETOBJ always returns native sized objects
90 2003-01-28 Zoltan Varga <vargaz@freemail.hu>
92 * x86.brg (mono_ldintftn): use <= instead of <, since the
93 interface_offsets array is max_interface_id + 1 long.
95 2003-01-28 Dietmar Maurer <dietmar@ximian.com>
97 * x86.brg (mono_ldintftn): fix from Zoltan: use max_interface_id
99 2003-01-27 Zoltan Varga <vargaz@freemail.hu>
101 * exception.c (ves_icall_get_trace): avoid crash if the exception is
104 * exception.c (ves_icall_get_trace): avoid crash on unmanaged frames.
106 2003-01-26 Martin Baulig <martin@ximian.com>
108 * debug.c (mono_debug_init): Take a boolean argument which
109 specifies whether we're running in the Mono Debugger.
111 2003-01-24 Martin Baulig <martin@ximian.com>
113 * debug.c (mono_debug_io_layer): Disable this on Windows.
115 2003-01-23 Dick Porter <dick@ximian.com>
117 * mono.c: Use mono_runtime_exec_managed_code() to run all managed
120 * jit.c: Changed thread start and attach callbacks to pass the
121 thread ID, not the MonoThread pointer. Arrange that managed code
122 execution will fail an assertion in the main thread, just to be
125 2003-01-22 Martin Baulig <martin@ximian.com>
127 * debug.c: Reverted Gonzalo's last change since it is wrong.
128 We're also using the debugging code on Windows, for instance the
129 stabs stuff when running in gdb. I hope this code still builds on
130 Windows; if not, we need to fix this.
131 Moved all the mono debugger support code into the debugger itself;
132 when debugging a managed application, the debugger new launches a
133 small unmanaged wrapper application which contains this stuff.
135 * debug.h (MonoDebuggerIOLayer): New public typedef; this is just
136 initialized to an array of function pointers to the io-layer
137 function; they don't seem to be public in the `libmono' library.
138 (mono_debugger_event): New public function. Sends the debugger an
139 event if we're running in the Mono Debugger and does nothing otherwise.
141 * mono.c: Don't initialize the Mono Debugger here.
143 * jit.c (mono_debug_insert_breakpoint): Removed, this isn't used anymore.
144 (mono_thread_start_cb, mono_thread_attach_cb): Call
145 mono_debugger_event() to send the debugger a callback.
147 2003-01-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
149 * debug.c: make all public symbols just dummy for windows.
151 2003-01-20 Miguel de Icaza <miguel@ximian.com>
153 * debug.c (initialize_debugger_support): ifdef out the call to
154 mono_debugger_init_thread_debug for the release.
156 Someone should look into why its not defined. I think the problem
157 is what Dick pointed out somewhere: code in io-layer is not
158 supposed to ever be used in Windows, so code for the debugger that
159 lives there must be moved elsewhere.
161 2003-01-19 Martin Baulig <martin@ximian.com>
163 * debug.c: Ok, this should now finally be working this time ....
165 2003-01-18 Martin Baulig <martin@ximian.com>
167 * debug.c (mono_debugger_jit_exec): Send the background thread a
168 SIGKILL before returning.
170 2003-01-17 Dietmar Maurer <dietmar@ximian.com>
172 * x86.brg: removed duplicated CONV_OVF_I4
174 2003-01-17 Martin Baulig <martin@ximian.com>
176 * debug.c: Don't use mono_once here. Reworked the API a bit to
177 use `mono_debug_' and `debug_' for the general debugging API and
178 `mono_debugger_' and `debugger_' for the Mono Debugger stuff.
180 2003-01-16 Martin Baulig <martin@ximian.com>
182 * debug.c (debugger_thread_func): We don't need to `raise
183 (SIGSTOP)' anymore; the thread manager already takes care of this.
185 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
187 * exception.c (arch_handle_exception): exclude runtime invoke
188 wrapper from the stack trace
190 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
191 (mono_thread_start_cb): save an additional LMF at thread start
193 2003-01-16 Martin Baulig <martin@ximian.com>
195 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
196 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
197 and the LinuxThreads port doesn't allow you to override the handler.
198 [FIXME: This avoids an assertion failure on startup, but there's
199 still an issue with thread termination.]
201 2003-01-16 Martin Baulig <martin@ximian.com>
203 * debug.c (debugger_thread_func): We don't need to `raise
204 (SIGSTOP)' anymore; the thread manager already takes care of this.
206 2003-01-16 Martin Baulig <martin@ximian.com>
208 * debug.c: Use the mono/io-layer functions here instead of gthread.
210 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
212 * jit.c (mono_jit_compile_method): make sure runtime_init is called
213 (mono_analyze_stack): make sure runtime_init is called
215 2003-01-14 Martin Baulig <martin@ximian.com>
217 * debug.c (debugger_update_symbol_file_table): Moved all the
218 functionality into debugger_update_symbol_file_table_internal();
219 the latter one will be called from the background thread while
220 already owning the lock. This'll allow us to step into
221 debugger_update_symbol_file_table() in the debugger and debug it.
223 2003-01-14 Martin Baulig <martin@ximian.com>
225 * Makefile.am: Link against gthread.
227 * jit.c: After realizing that mono-mutex doesn't work either
228 because it doesn't support recursive mutexes on FreeBSD, rewrote
229 the whole thread stuff to use gthread. This seems to fix this
230 weird deadlock in the debugger as well.
232 2003-01-12 Alp Toker <alp@atoker.com>
234 * exception.c: Typo fix: insinde -> inside
236 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
238 * exception.c (ves_icall_get_frame_info): skip one more frame and also
239 MONO_WRAPPER_RUNTIME_INVOKE wrappers
240 (x86_unwind_native_frame): disable unnecessary assertion
242 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
244 * exception.c (ves_icall_get_frame_info): fix bug 36382
246 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
248 * jit.c: handle wrapper_data in NEWOBJ/CALL.
250 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
252 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
254 2003-01-06 Martin Baulig <martin@ximian.com>
256 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
258 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
259 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
261 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
263 * debug.c: Move must_send_finished var declaration out of #if win32
264 block (this fixes the build on win32)
266 2003-01-05 Martin Baulig <martin@ximian.com>
268 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
269 this is used when we're running inside the Mono Debugger
270 (mono_debugger_wait): Put the waiting code into a function of its own.
272 * mono.c (main): Call mono_debugger_jit_exec() instead of
273 mono_jit_exec() if we're running inside the Mono Debugger.
275 2003-01-05 Martin Baulig <martin@ximian.com>
277 * debug.h (MonoDebugFormat): Added
278 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
279 we're running inside the Mono Debugger prior to the args parsing.
281 2003-01-04 Martin Baulig <martin@ximian.com>
283 * debug.c (release_symbol_file_table): Only call this if we're
284 actually modifying the symbol tables.
285 (mono_debug_open): Always set the `mono_debugger_class_init_func'
286 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
288 2003-01-03 Martin Baulig <martin@ximian.com>
290 * debug.c: Disable the mono debugger stuff on Windows.
292 2003-01-03 Martin Baulig <martin@ximian.com>
294 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
295 function. This is called from the breakpoint trampoline to signal
296 the debugger and wait until it has reload the symbol tables.
298 * trampoline.c (get_breakpoint_trampoline): Call the new
299 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
300 trampoline just before the breakpoint.
302 2002-12-31 Martin Baulig <martin@ximian.com>
304 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
305 field to point to the MonoGlobalSymbolTable.
307 2002-12-30 Martin Baulig <martin@ximian.com>
309 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
310 This variable now specifies that the symbol tables have been
311 modified after the last notification has been send. The debugger
312 uses this flag to check whether it needs to reload the symbol
314 (debugger_compile_method): Just send a notification to the
315 debugger, but don't set the modified flag. It may or may not be
316 set when the debugger gets the notification - depending on whether
317 the JIT compilation added a new method to the symbol tables.
319 2002-12-30 Martin Baulig <martin@ximian.com>
321 * debug.c (debugger_compile_method): This is a wrapper around
322 mono_compile_method() which always sends a notification to the
325 2002-12-30 Martin Baulig <martin@ximian.com>
327 * debug.c: Reload the symbol file table before sending the
328 notification event to the debugger.
329 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
331 2002-12-31 Martin Baulig <martin@ximian.com>
333 * debug.c: Propertly lock everything and avoid race conditions.
334 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
336 2002-12-31 Duncan Mak <duncan@ximian.com>
338 * debug.c (initialize_debugger_support): Fix build error by
339 declaring ret at the top of the function.
341 2002-12-30 Martin Baulig <martin@ximian.com>
343 * debug.c: When running under the mono debugger, create a special
344 debugger thread; always protect the symbol tables with a mutex.
346 2002-12-28 Martin Baulig <martin@ximian.com>
348 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
349 incremented each time one of the symbol tables is modified.
351 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
353 * jit.c: fix LDELEMA implementation here as well.
355 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
357 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
359 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
361 * jit.c: query the thread abort signal from the runtime.
363 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
365 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
367 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
369 * jit.c (mono_analyze_stack): call the utility function
370 mono_field_from_token to avoid code duplication.
372 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
374 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
376 * x86.brg (stmt): POP floating point stack correctly
378 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
380 * emit-x86.c (arch_emit_prologue): don't save caller saved
383 * exception.c (x86_unwind_native_frame): support exceptions inside
384 native code using gcc generated exception tables (-fexception).
386 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
388 * exception.c: include some code from Zoltan Varga, but modified
391 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
393 * exception.c: massive code cleanups. The code is still
394 architecture dependent, but it should be now possible to reuse the
395 complex parts for other architecture.
397 2002-11-15 Dick Porter <dick@ximian.com>
399 * jit.c: Pass the attach callback to mono_runtime_init().
401 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
403 * jit.c: display the domain name in trace output.
405 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
407 * x86.brg (reg): fix bug #2721
409 * jit.c (mono_runtime_install_handlers): impl.
411 2002-10-17 Martin Baulig <martin@gnome.org>
413 * debug.c (mono_debug_add_method): Make this actually work if we don't
414 have any lifetime information.
416 2002-10-15 Martin Baulig <martin@gnome.org>
418 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
420 * debug.c (generate_line_number): Small fix to make this actually
421 work for more complex things.
423 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
425 * x86.brg (freg): use fprem instead of fprem1
427 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
429 * jit.c (ves_array_element_address): added check for out of range index
430 (mono_analyze_stack): added fix for bug #31654
432 2002-10-01 Martin Baulig <martin@gnome.org>
434 * debug.c: Don't create an .il file for the dynamic symbol file.
436 2002-10-01 Martin Baulig <martin@gnome.org>
438 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
440 2002-09-27 Martin Baulig <martin@gnome.org>
442 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
444 2002-09-27 Dick Porter <dick@ximian.com>
446 * mono.c: Tell glib what the program name is, by passing it the
447 name of the managed file we're executing
449 2002-09-26 Martin Baulig <martin@gnome.org>
451 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
452 trampoline into the vtable, also use it for non-virtual methods,
453 remove the breakpoint when done.
455 2002-09-26 Martin Baulig <martin@gnome.org>
457 * debug.c (debug_load_method_lines): Block SIGCHLD while running
460 2002-09-26 Martin Baulig <martin@gnome.org>
462 * debug.c: Reworked the whole debugging stuff. We have now one
463 single `mono_debug_handle' which keeps a hashtable of
464 `AssemblyDebugInfo's (which may have different debugging formats).
465 The AssemblyDebugInfo is now created when the assembly is loaded,
466 but never when adding a class/type.
468 * mono.c: Initialize debugging stuff after corlib and the assembly
471 2002-09-25 Martin Baulig <martin@gnome.org>
473 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
474 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
476 (DebugMethodInfo): Removed `line_numbers'.
478 * debug.c: Reworked the line number generation; we're now using
479 the MonoDebugLineNumberEntry try for all debugging formats. This
480 type also includes the line number and IL offset, this allows the
481 JIT to produce better line number info: we only emit line number
482 information for source lines which actually have code.
484 2002-09-25 Martin Baulig <martin@gnome.org>
486 * debug.h: Removed external declaration of all functions which
487 should only be called from the Mono Debugger and also made them
488 static. Since the debugger gets their address from the
489 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
492 2002-09-25 Martin Baulig <martin@gnome.org>
494 Improved breakpoint support, we can now dynamically insert and
495 remove breakpoints at runtime and when called from withing the
496 Mono Debugger, we're using a special breakpoint trampoline.
498 * debug.h (mono_method_has_breakpoint): New method to check
499 whether to insert a breakpoint for a method.
500 (mono_insert_breakpoint): New method to insert a breakpoint.
501 (mono_insert_breakpoint_full): New method to insert a breakpoint,
502 takes a MonoMethodDesc.
503 (mono_remove_breakpoint): New method to remove a breakpoint.
505 * debug.c (mono_debugger_insert_breakpoint): New function for the
506 debugger. Should only be called from the debugger.
507 (mono_debugger_remove_breakpoint): Likewise.
509 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
511 * trampoline.c (get_breakpoint_trampoline): New static function to
512 create a special breakpoint trampoline for the debugger.
513 (x86_magic_trampoline): If we're running inside the Mono Debugger
514 and a breakpoint was requested for the method, generate a special
515 breakpoint trampoline.
517 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
518 to insert a breakpoint.
519 (mono_debug_last_breakpoint_address): Removed.
520 (match_debug_method): Removed, use mono_method_has_breakpoint().
522 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
524 * jit.c: reorder mono_runtime_cleanup () call since it needs the
525 engine still fully working.
527 2002-09-24 Martin Baulig <martin@gnome.org>
529 * debug.c (mono_debug_open): When we're invoked from inside the
530 Mono Debugger, set mono_debugger_class_init_func (exported in
531 metadata/class.c) to mono_add_type().
532 (mono_add_type): Call mono_debug_symfile_add_type().
534 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
536 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
537 Run finalize on domain cleanup.
538 * mono.c: call setlocale ().
539 * trampoline.c: clearer error message for invalid trampoline.
541 2002-09-21 Martin Baulig <martin@gnome.org>
543 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
544 instead of writing a byte blob.
545 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
546 (mono_debug_add_method): Incrementally add the new method to the symbol
549 * exception.c (arch_handle_exception): If we have debugging support,
550 call mono_debugger_update_symbol_file_table () as well.
552 2002-09-20 Martin Baulig <martin@gnome.org>
554 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
555 the size of the variable.
557 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
559 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
560 iterations if we visit blocks in reverse order.
562 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
564 * jit.c (mono_analyze_stack): cleaup of the array code
566 * exception.c: added patch from Julio Merno to fix bug #30048
568 * jit.c (mono_analyze_stack): code cleanup, fix bug #29365
570 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
572 * x86.brg (LDELEMA): use x86_lea
574 2002-09-06 Martin Baulig <martin@gnome.org>
576 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
577 If you were getting random crashes when using the JIT with debugging

605 `mono_symfile' to `symfile'.
607 * debug.c (mono_debug_open): Replaced the assembly argument with a
608 file name argument; you can now call this before loading the assembly.
609 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
610 we now use MonoSymbolFileLineNumberEntry's and a separate address array
611 instead; splitted out all MonoSymbolFileLineNumberEntry code into
612 debug_generate_il_offsets() and debug_update_il_offsets().
613 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
614 created when reading the symbol file or from debug_load_method_lines().
615 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.

643 2002-08-27 Martin Baulig <martin@gnome.org>
645 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need

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

712 2002-08-19 Nick Drochak <ndrochak@gol.com>
714 * x86.brg (mono_llmult_ovf): Simplified the code greatly by refactoring
715 the algebraic form we are using. This also eliminated a silly overflow
716 of the intermediate result that was causing troubles.
718 2002-08-16 Nick Drochak <ndrochak@gol.com>
720 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers

745 versions of linuxthreads.
747 * jit.c (mono_runtime_install_handlers): switch back to use

1193 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
1194 file for all assemblies. Currently, the JIT doesn't put all methods
1195 from a single assembly into a continuous region of memory. We were
1196 previously creating valid DWARF 2 files for this, but unfortunately
1197 GDB's symbol tables get messed up when it reads more than one such file.
1199 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

1293 SHL/SHR because the tree allocator can fail otherwise
1295 * exception.c (arch_handle_exception): EIP now points to the call
1296 instruction, not to the instruction after the call. This fixes the
1297 bug reported by Linus Upson (tests/exception8.cs)

1864 (mono_debug_open_file): Added MonoDebugFormat argument.
1865 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1866 this function from GDB. It's now safe to call this function multiple times;
1867 it'll always write a complete debugging file.
1869 * debug.c: Splitted this file into a general part which remains in this file
1870 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1871 All public functions now call a corresponding format specific function.
1873 * debug.c: The following changes are private to debug.c:
1874 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1875 (record_line_number, debug_generate_method_lines): New private functions.
1876 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1877 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1878 mono_debug_open_assembly_dwarf2).
1879 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1880 now safe to call this function multiple times.
1881 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1882 returns an unique index for this type. It's used to ensure that we only write
1883 each class once to the debugging file.
1884 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1885 data structure, but don't directly write to the debugging file. This is done
1886 later from mono_debug_write_assembly().
1888 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1889 debugging output. Call mono_debug_close() on cleanup if necessary.

1893 * debug-private.h: New private header file.
1895 * debug-stabs.c: Added the stabs type generation stuff which was
1896 previously in debug.c.

1899 only writing this most basic types to the dwarf file, but this will
1902 2002-03-13 Martin Baulig <martin@gnome.org>
1904 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1905 debugging code. They're now in CVS, but not yet used anywhere.
1907 2002-03-11 Dietmar Maurer <dietmar@ximian.com>

1915 * jit.c: verify that corlib and runtime are in sync.
1917 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1919 * emit-x86.c, jit.c: use the debug-helpers facilities to
1920 describe and match a method when debugging.
1922 2002-03-10 Martin Baulig <martin@gnome.org>
1924 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1925 output, put a nop instruction at the start of all functions so that
1926 the adresses won't change when using --debug.
1928 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1929 the bytecode area, stabs needs a line number in the .il file. Use the
1930 new info->moffsets to get the line number.
1931 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1932 `moffsets' is an array of `total_lines' fields (total number of lines
1933 in the .il file); for each line in the .il field, this array contains
1934 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1935 of a method and 0 otherwise.
1936 (debug_load_method_lines): Read the whole .il file and initialize the
1937 info->moffsets field.
1939 2002-03-09 Martin Baulig <martin@gnome.org>
1941 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1942 the unnecessary CDQ instruction.
