7 MONO_DEBUGGER_EVENT_THREAD_CREATED event.
9 2003-03-13 Martin Baulig <martin@ximian.com>
11 * debug.c (_mono_debug_address_from_il_offset): Moved to
12 ../metadata/debug-mono-symfile.c
14 2003-03-07 Martin Baulig <martin@ximian.com>
16 * debug-jit.c: #include <config.h>.
18 2003-03-05 Martin Baulig <martin@ximian.com>
20 * debug-jit.c, debug-jit.h: New files. Moved all JIT-specific
23 * debug.c (mono_debug_add_method): Moved to debug-jit.c.
24 (mono_debug_handle, mono_debug_initialized): Made them global.
25 (replace_suffix): Removed, this isn't used anymore.
26 (record_line_number): Moved to debug-jit.c.
27 (debug_generate_method_lines): Moved to debug-jit.c
28 (generate_line_number): Renamed to
29 _mono_debug_generate_line_number() and made it global.
30 (debug_update_il_offsets): Moved to debug-jit.c
31 (mono_debug_get_image): Renamed to _mono_debug_get_image() and made
33 (address_from_il_offset): Renamed to
34 _mono_debug_address_from_il_offset() and made it global.
35 (il_offset_from_position): Moved to debug-jit.c
36 (lookup_method): Renamed to _mono_debug_lookup_method() and made
38 (mono_debug_add_method): Moved to debug-jit.c.
39 (mono_debug_create_notification_function): Use two new functions
40 mono_debug_codegen_breakpoint() and mono_debug_codegen_ret()
41 instead of x86_breakpoint() and x86_ret().
43 Sat Mar 1 12:36:45 CET 2003 Paolo Molaro <lupus@ximian.com>
45 * jit.c: remove unnecessary assert when inlining.
47 2003-02-17 Martin Baulig <martin@ximian.com>
49 * jit.c (mono_jit_compile_method): Don't emit a `nop' at the start
52 2003-02-14 Patrik Torstensson
54 * x86.brg: Implemented CONV_OVF_[I|U]4 (freg), this fixes the issues
55 with the "checked" keyword. Closes bugs #33421 and #35280 (JIT not mint)
57 2003-02-14 Dietmar Maurer <dietmar@ximian.com>
59 * exception.c (mono_arch_find_jit_info): better way to handle
60 situations where we have no MonoJitInfo
62 2003-02-11 Zoltan Varga <vargaz@freemail.hu>
64 * trampoline.c (arch_create_jit_trampoline): This function should
65 allways return a trampoline for managed methods. Fixes bug #29859.
67 2003-02-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
69 * debug.c: allocate debug->source_files. Fixes GLib-CRITICAL upon
72 2003-02-02 Martin Baulig <martin@ximian.com>
74 * debug.c (mono_debug_add_wrapper): Lookup the wrapper method in a
75 hash table; we need to provide the correct code_size.
77 2003-02-02 Martin Baulig <martin@ximian.com>
79 * jit.c (mono_jit_compile_method): Call mono_debug_add_wrapper()
80 to add the interncall to the symbol file.
82 * debug.c (mono_debug_add_wrapper): New public function.
84 2003-02-02 Martin Baulig <martin@ximian.com>
86 * debug.c (debug_update_il_offsets): Set the prologue end address
87 to the address of the first source line.
89 2003-01-31 Dietmar Maurer <dietmar@ximian.com>
91 * jit.c (mono_analyze_stack): use the wrapper signature if necessary
93 2003-01-31 Zoltan Varga <vargaz@freemail.hu>
95 * debug.c (mono_debug_open_image): dynamic assemblies have no debug
98 Thu Jan 30 11:07:06 CET 2003 Paolo Molaro <lupus@ximian.com>
100 * helper.c: handle MONO_TYPE_ARRAY as well.
102 2003-01-29 Dietmar Maurer <dietmar@ximian.com>
104 * jit.c (mono_analyze_stack): impl. CEE_MONO_LDNATIVEOBJ
105 (mono_analyze_stack): RETOBJ always returns native sized objects
107 2003-01-28 Zoltan Varga <vargaz@freemail.hu>
109 * x86.brg (mono_ldintftn): use <= instead of <, since the
110 interface_offsets array is max_interface_id + 1 long.
112 2003-01-28 Dietmar Maurer <dietmar@ximian.com>
114 * x86.brg (mono_ldintftn): fix from Zoltan: use max_interface_id
116 2003-01-27 Zoltan Varga <vargaz@freemail.hu>
118 * exception.c (ves_icall_get_trace): avoid crash if the exception is
121 * exception.c (ves_icall_get_trace): avoid crash on unmanaged frames.
123 2003-01-26 Martin Baulig <martin@ximian.com>
125 * debug.c (mono_debug_init): Take a boolean argument which
126 specifies whether we're running in the Mono Debugger.
128 2003-01-24 Martin Baulig <martin@ximian.com>
130 * debug.c (mono_debug_io_layer): Disable this on Windows.
132 2003-01-23 Dick Porter <dick@ximian.com>
134 * mono.c: Use mono_runtime_exec_managed_code() to run all managed
137 * jit.c: Changed thread start and attach callbacks to pass the
138 thread ID, not the MonoThread pointer. Arrange that managed code
139 execution will fail an assertion in the main thread, just to be
142 2003-01-22 Martin Baulig <martin@ximian.com>
144 * debug.c: Reverted Gonzalo's last change since it is wrong.
145 We're also using the debugging code on Windows, for instance the
146 stabs stuff when running in gdb. I hope this code still builds on
147 Windows; if not, we need to fix this.
148 Moved all the mono debugger support code into the debugger itself;
149 when debugging a managed application, the debugger new launches a
150 small unmanaged wrapper application which contains this stuff.
152 * debug.h (MonoDebuggerIOLayer): New public typedef; this is just
153 initialized to an array of function pointers to the io-layer
154 function; they don't seem to be public in the `libmono' library.
155 (mono_debugger_event): New public function. Sends the debugger an
156 event if we're running in the Mono Debugger and does nothing otherwise.
158 * mono.c: Don't initialize the Mono Debugger here.
160 * jit.c (mono_debug_insert_breakpoint): Removed, this isn't used anymore.
161 (mono_thread_start_cb, mono_thread_attach_cb): Call
162 mono_debugger_event() to send the debugger a callback.
164 2003-01-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
166 * debug.c: make all public symbols just dummy for windows.
168 2003-01-20 Miguel de Icaza <miguel@ximian.com>
170 * debug.c (initialize_debugger_support): ifdef out the call to
171 mono_debugger_init_thread_debug for the release.
173 Someone should look into why its not defined. I think the problem
174 is what Dick pointed out somewhere: code in io-layer is not
175 supposed to ever be used in Windows, so code for the debugger that
176 lives there must be moved elsewhere.
178 2003-01-19 Martin Baulig <martin@ximian.com>
180 * debug.c: Ok, this should now finally be working this time ....
182 2003-01-18 Martin Baulig <martin@ximian.com>
184 * debug.c (mono_debugger_jit_exec): Send the background thread a
185 SIGKILL before returning.
187 2003-01-17 Dietmar Maurer <dietmar@ximian.com>
189 * x86.brg: removed duplicated CONV_OVF_I4
191 2003-01-17 Martin Baulig <martin@ximian.com>
193 * debug.c: Don't use mono_once here. Reworked the API a bit to
194 use `mono_debug_' and `debug_' for the general debugging API and
195 `mono_debugger_' and `debugger_' for the Mono Debugger stuff.
197 2003-01-16 Martin Baulig <martin@ximian.com>
199 * debug.c (debugger_thread_func): We don't need to `raise
200 (SIGSTOP)' anymore; the thread manager already takes care of this.
202 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
204 * exception.c (arch_handle_exception): exclude runtime invoke
205 wrapper from the stack trace
207 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
208 (mono_thread_start_cb): save an additional LMF at thread start
210 2003-01-16 Martin Baulig <martin@ximian.com>
212 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
213 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
214 and the LinuxThreads port doesn't allow you to override the handler.
215 [FIXME: This avoids an assertion failure on startup, but there's
216 still an issue with thread termination.]
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 Martin Baulig <martin@ximian.com>
225 * debug.c: Use the mono/io-layer functions here instead of gthread.
227 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
229 * jit.c (mono_jit_compile_method): make sure runtime_init is called
230 (mono_analyze_stack): make sure runtime_init is called
232 2003-01-14 Martin Baulig <martin@ximian.com>
234 * debug.c (debugger_update_symbol_file_table): Moved all the
235 functionality into debugger_update_symbol_file_table_internal();
236 the latter one will be called from the background thread while
237 already owning the lock. This'll allow us to step into
238 debugger_update_symbol_file_table() in the debugger and debug it.
240 2003-01-14 Martin Baulig <martin@ximian.com>
242 * Makefile.am: Link against gthread.
244 * jit.c: After realizing that mono-mutex doesn't work either
245 because it doesn't support recursive mutexes on FreeBSD, rewrote
246 the whole thread stuff to use gthread. This seems to fix this
247 weird deadlock in the debugger as well.
249 2003-01-12 Alp Toker <alp@atoker.com>
251 * exception.c: Typo fix: insinde -> inside
253 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
255 * exception.c (ves_icall_get_frame_info): skip one more frame and also
256 MONO_WRAPPER_RUNTIME_INVOKE wrappers
257 (x86_unwind_native_frame): disable unnecessary assertion
259 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
261 * exception.c (ves_icall_get_frame_info): fix bug 36382
263 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
265 * jit.c: handle wrapper_data in NEWOBJ/CALL.
267 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
269 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
271 2003-01-06 Martin Baulig <martin@ximian.com>
273 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
275 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
276 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
278 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
280 * debug.c: Move must_send_finished var declaration out of #if win32
281 block (this fixes the build on win32)
283 2003-01-05 Martin Baulig <martin@ximian.com>
285 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
286 this is used when we're running inside the Mono Debugger
287 (mono_debugger_wait): Put the waiting code into a function of its own.
289 * mono.c (main): Call mono_debugger_jit_exec() instead of
290 mono_jit_exec() if we're running inside the Mono Debugger.
292 2003-01-05 Martin Baulig <martin@ximian.com>
294 * debug.h (MonoDebugFormat): Added
295 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
296 we're running inside the Mono Debugger prior to the args parsing.
298 2003-01-04 Martin Baulig <martin@ximian.com>
300 * debug.c (release_symbol_file_table): Only call this if we're
301 actually modifying the symbol tables.
302 (mono_debug_open): Always set the `mono_debugger_class_init_func'
303 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
305 2003-01-03 Martin Baulig <martin@ximian.com>
307 * debug.c: Disable the mono debugger stuff on Windows.
309 2003-01-03 Martin Baulig <martin@ximian.com>
311 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
312 function. This is called from the breakpoint trampoline to signal
313 the debugger and wait until it has reload the symbol tables.
315 * trampoline.c (get_breakpoint_trampoline): Call the new
316 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
317 trampoline just before the breakpoint.
319 2002-12-31 Martin Baulig <martin@ximian.com>
321 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
322 field to point to the MonoGlobalSymbolTable.
324 2002-12-30 Martin Baulig <martin@ximian.com>
326 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
327 This variable now specifies that the symbol tables have been
328 modified after the last notification has been send. The debugger
329 uses this flag to check whether it needs to reload the symbol
331 (debugger_compile_method): Just send a notification to the
332 debugger, but don't set the modified flag. It may or may not be
333 set when the debugger gets the notification - depending on whether
334 the JIT compilation added a new method to the symbol tables.
336 2002-12-30 Martin Baulig <martin@ximian.com>
338 * debug.c (debugger_compile_method): This is a wrapper around
339 mono_compile_method() which always sends a notification to the
342 2002-12-30 Martin Baulig <martin@ximian.com>
344 * debug.c: Reload the symbol file table before sending the
345 notification event to the debugger.
346 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
348 2002-12-31 Martin Baulig <martin@ximian.com>
350 * debug.c: Propertly lock everything and avoid race conditions.
351 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
353 2002-12-31 Duncan Mak <duncan@ximian.com>
355 * debug.c (initialize_debugger_support): Fix build error by
356 declaring ret at the top of the function.
358 2002-12-30 Martin Baulig <martin@ximian.com>
360 * debug.c: When running under the mono debugger, create a special
361 debugger thread; always protect the symbol tables with a mutex.
363 2002-12-28 Martin Baulig <martin@ximian.com>
365 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
366 incremented each time one of the symbol tables is modified.
368 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
370 * jit.c: fix LDELEMA implementation here as well.
372 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
374 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
376 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
378 * jit.c: query the thread abort signal from the runtime.
380 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
382 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
384 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
386 * jit.c (mono_analyze_stack): call the utility function
387 mono_field_from_token to avoid code duplication.
389 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
391 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
393 * x86.brg (stmt): POP floating point stack correctly
395 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
397 * emit-x86.c (arch_emit_prologue): don't save caller saved
400 * exception.c (x86_unwind_native_frame): support exceptions inside
401 native code using gcc generated exception tables (-fexception).
403 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
405 * exception.c: include some code from Zoltan Varga, but modified
408 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
410 * exception.c: massive code cleanups. The code is still
411 architecture dependent, but it should be now possible to reuse the
412 complex parts for other architecture.
414 2002-11-15 Dick Porter <dick@ximian.com>
416 * jit.c: Pass the attach callback to mono_runtime_init().
418 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
420 * jit.c: display the domain name in trace output.
422 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
424 * x86.brg (reg): fix bug #2721
426 * jit.c (mono_runtime_install_handlers): impl.
428 2002-10-17 Martin Baulig <martin@gnome.org>
430 * debug.c (mono_debug_add_method): Make this actually work if we don't
431 have any lifetime information.
433 2002-10-15 Martin Baulig <martin@gnome.org>
435 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
437 * debug.c (generate_line_number): Small fix to make this actually
438 work for more complex things.
440 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
442 * x86.brg (freg): use fprem instead of fprem1
444 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
446 * jit.c (ves_array_element_address): added check for out of range index
447 (mono_analyze_stack): added fix for bug #31654
449 2002-10-01 Martin Baulig <martin@gnome.org>
451 * debug.c: Don't create an .il file for the dynamic symbol file.
453 2002-10-01 Martin Baulig <martin@gnome.org>
455 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
457 2002-09-27 Martin Baulig <martin@gnome.org>
459 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
461 2002-09-27 Dick Porter <dick@ximian.com>
463 * mono.c: Tell glib what the program name is, by passing it the
464 name of the managed file we're executing
466 2002-09-26 Martin Baulig <martin@gnome.org>
468 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
469 trampoline into the vtable, also use it for non-virtual methods,
470 remove the breakpoint when done.
472 2002-09-26 Martin Baulig <martin@gnome.org>
474 * debug.c (debug_load_method_lines): Block SIGCHLD while running
477 2002-09-26 Martin Baulig <martin@gnome.org>
479 * debug.c: Reworked the whole debugging stuff. We have now one
480 single `mono_debug_handle' which keeps a hashtable of
481 `AssemblyDebugInfo's (which may have different debugging formats).
482 The AssemblyDebugInfo is now created when the assembly is loaded,
483 but never when adding a class/type.
485 * mono.c: Initialize debugging stuff after corlib and the assembly
488 2002-09-25 Martin Baulig <martin@gnome.org>
490 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
491 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
493 (DebugMethodInfo): Removed `line_numbers'.
495 * debug.c: Reworked the line number generation; we're now using
496 the MonoDebugLineNumberEntry try for all debugging formats. This
497 type also includes the line number and IL offset, this allows the
498 JIT to produce better line number info: we only emit line number
499 information for source lines which actually have code.
501 2002-09-25 Martin Baulig <martin@gnome.org>
503 * debug.h: Removed external declaration of all functions which
504 should only be called from the Mono Debugger and also made them
505 static. Since the debugger gets their address from the
506 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
509 2002-09-25 Martin Baulig <martin@gnome.org>
511 Improved breakpoint support, we can now dynamically insert and
512 remove breakpoints at runtime and when called from withing the
513 Mono Debugger, we're using a special breakpoint trampoline.
515 * debug.h (mono_method_has_breakpoint): New method to check
516 whether to insert a breakpoint for a method.
517 (mono_insert_breakpoint): New method to insert a breakpoint.
518 (mono_insert_breakpoint_full): New method to insert a breakpoint,
519 takes a MonoMethodDesc.
520 (mono_remove_breakpoint): New method to remove a breakpoint.
522 * debug.c (mono_debugger_insert_breakpoint): New function for the
523 debugger. Should only be called from the debugger.
524 (mono_debugger_remove_breakpoint): Likewise.
526 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
528 * trampoline.c (get_breakpoint_trampoline): New static function to
529 create a special breakpoint trampoline for the debugger.
530 (x86_magic_trampoline): If we're running inside the Mono Debugger
531 and a breakpoint was requested for the method, generate a special
532 breakpoint trampoline.
534 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
535 to insert a breakpoint.
536 (mono_debug_last_breakpoint_address): Removed.
537 (match_debug_method): Removed, use mono_method_has_breakpoint().
539 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
541 * jit.c: reorder mono_runtime_cleanup () call since it needs the
542 engine still fully working.
544 2002-09-24 Martin Baulig <martin@gnome.org>
546 * debug.c (mono_debug_open): When we're invoked from inside the
547 Mono Debugger, set mono_debugger_class_init_func (exported in
548 metadata/class.c) to mono_add_type().
549 (mono_add_type): Call mono_debug_symfile_add_type().
551 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
553 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
554 Run finalize on domain cleanup.
555 * mono.c: call setlocale ().
556 * trampoline.c: clearer error message for invalid trampoline.
558 2002-09-21 Martin Baulig <martin@gnome.org>
560 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
561 instead of writing a byte blob.
562 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
563 (mono_debug_add_method): Incrementally add the new method to the symbol
566 * exception.c (arch_handle_exception): If we have debugging support,
567 call mono_debugger_update_symbol_file_table () as well.
569 2002-09-20 Martin Baulig <martin@gnome.org>
571 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
572 the size of the variable.
574 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
576 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
577 iterations if we visit blocks in reverse order.

622 `mono_symfile' to `symfile'.
624 * debug.c (mono_debug_open): Replaced the assembly argument with a
625 file name argument; you can now call this before loading the assembly.
626 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
627 we now use MonoSymbolFileLineNumberEntry's and a separate address array
628 instead; splitted out all MonoSymbolFileLineNumberEntry code into
629 debug_generate_il_offsets() and debug_update_il_offsets().
630 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
631 created when reading the symbol file or from debug_load_method_lines().

660 2002-08-27 Martin Baulig <martin@gnome.org>
662 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need

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

731 * x86.brg (mono_llmult_ovf): Simplified the code greatly by refactoring
732 the algebraic form we are using. This also eliminated a silly overflow
733 of the intermediate result that was causing troubles.
735 2002-08-16 Nick Drochak <ndrochak@gol.com>
737 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers

762 versions of linuxthreads.
764 * jit.c (mono_runtime_install_handlers): switch back to use

1172 all methods in a class here from main().
1173 (--compile): The argument can now also be an image (in `@imagename' format).
1174 Updated documentation for this command line argument.
1175 (--precompile): New command line argument to precompile an image/class/method
1176 before executing the main app. This argument can be given multiple times.

1210 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
1211 file for all assemblies. Currently, the JIT doesn't put all methods
1212 from a single assembly into a continuous region of memory. We were
1213 previously creating valid DWARF 2 files for this, but unfortunately
1214 GDB's symbol tables get messed up when it reads more than one such file.
1216 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',
1217 `next_idx', `methods', `type_hash', `source_files' and `format'

1310 SHL/SHR because the tree allocator can fail otherwise
1312 * exception.c (arch_handle_exception): EIP now points to the call
1313 instruction, not to the instruction after the call. This fixes the
1314 bug reported by Linus Upson (tests/exception8.cs)

1762 2002-03-23 Martin Baulig <martin@gnome.org>
1764 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1765 to do it before the X86_CMP.
1766 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1767 (reg: CLT (lreg, lreg)): Likewise.

1881 (mono_debug_open_file): Added MonoDebugFormat argument.
1882 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1883 this function from GDB. It's now safe to call this function multiple times;
1884 it'll always write a complete debugging file.
1886 * debug.c: Splitted this file into a general part which remains in this file
1887 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1888 All public functions now call a corresponding format specific function.
1890 * debug.c: The following changes are private to debug.c:
1891 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1892 (record_line_number, debug_generate_method_lines): New private functions.
1893 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1894 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1895 mono_debug_open_assembly_dwarf2).
1896 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1897 now safe to call this function multiple times.
1898 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1899 returns an unique index for this type. It's used to ensure that we only write
1900 each class once to the debugging file.
1901 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1902 data structure, but don't directly write to the debugging file. This is done
1903 later from mono_debug_write_assembly().
1905 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1906 debugging output. Call mono_debug_close() on cleanup if necessary.

1910 * debug-private.h: New private header file.
1912 * debug-stabs.c: Added the stabs type generation stuff which was
1913 previously in debug.c.

1916 only writing this most basic types to the dwarf file, but this will
1919 2002-03-13 Martin Baulig <martin@gnome.org>
1921 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1922 debugging code. They're now in CVS, but not yet used anywhere.
1924 2002-03-11 Dietmar Maurer <dietmar@ximian.com>

1932 * jit.c: verify that corlib and runtime are in sync.
1934 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1936 * emit-x86.c, jit.c: use the debug-helpers facilities to
1937 describe and match a method when debugging.
1939 2002-03-10 Martin Baulig <martin@gnome.org>
1941 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1942 output, put a nop instruction at the start of all functions so that
1943 the adresses won't change when using --debug.
1945 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1946 the bytecode area, stabs needs a line number in the .il file. Use the
1947 new info->moffsets to get the line number.
1948 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1949 `moffsets' is an array of `total_lines' fields (total number of lines
1950 in the .il file); for each line in the .il field, this array contains
1951 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1952 of a method and 0 otherwise.
1953 (debug_load_method_lines): Read the whole .il file and initialize the
1954 info->moffsets field.
1956 2002-03-09 Martin Baulig <martin@gnome.org>
1958 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1959 the unnecessary CDQ instruction.
