3 * jit.c: Netbsd build fix by marc@informatik.uni-bremen.de.
5 Thu Apr 24 17:11:03 CEST 2003 Paolo Molaro <lupus@ximian.com>
7 * Makefile.am: rename mono and libmono to oldmono and liboldmono.
9 2003-04-23 Martin Baulig <martin@ximian.com>
11 * mono.c: The `--debug' command line argument doesn't take any
12 arguments anymore, removed the `--debug-args' argument.
14 * debug-jit.c (mono_debug_add_method): Renamed this to
15 mono_debug_jit_add_method(); create the JIT-specific data
16 structure and pass it to mono_debug_add_method().
18 * debug.[ch]: Removed. The code is now in
19 ../metadata/mono-debug.[ch] and mono-debug-debugger.[ch].
21 * debug-stabs.c, debug-dwarf2.c: Removed; nobody used this for the
24 2003-04-21 Martin Baulig <martin@ximian.com>
26 * debug.c (mono_debug_open): Splitted into mono_debug_init() and
28 (mono_debug_open_image): Don't open referenced assemblies; this is
29 done automatically by the code in assembly.c.
31 * mono.c (main_thread_handler): Call mono_debug_init() before
32 opening the assembly because we need to install the assembly load
35 2003-04-17 Gonzalo Paniagua Javier <gonzalo@ximian.com>
38 (mono_jit_cleanup): moved mono_runtime_cleanup call after the call to
41 2003-04-05 Miguel de Icaza <miguel@ximian.com>
43 * jit.c (check_inlining): honor the NOINLING atttribute.
45 2003-03-31 Martin Baulig <martin@ximian.com>
47 * debug.h (MonoDebuggerEvent): Removed
48 MONO_DEBUGGER_EVENT_THREAD_CREATED.
50 * jit.c (mono_thread_start_cb): Don't send the
51 MONO_DEBUGGER_EVENT_THREAD_CREATED event.
53 2003-03-13 Martin Baulig <martin@ximian.com>
55 * debug.c (_mono_debug_address_from_il_offset): Moved to
56 ../metadata/debug-mono-symfile.c
58 2003-03-07 Martin Baulig <martin@ximian.com>
60 * debug-jit.c: #include <config.h>.
62 2003-03-05 Martin Baulig <martin@ximian.com>
64 * debug-jit.c, debug-jit.h: New files. Moved all JIT-specific
67 * debug.c (mono_debug_add_method): Moved to debug-jit.c.
68 (mono_debug_handle, mono_debug_initialized): Made them global.
69 (replace_suffix): Removed, this isn't used anymore.
70 (record_line_number): Moved to debug-jit.c.
71 (debug_generate_method_lines): Moved to debug-jit.c
72 (generate_line_number): Renamed to
73 _mono_debug_generate_line_number() and made it global.
74 (debug_update_il_offsets): Moved to debug-jit.c
75 (mono_debug_get_image): Renamed to _mono_debug_get_image() and made
77 (address_from_il_offset): Renamed to
78 _mono_debug_address_from_il_offset() and made it global.
79 (il_offset_from_position): Moved to debug-jit.c
80 (lookup_method): Renamed to _mono_debug_lookup_method() and made
82 (mono_debug_add_method): Moved to debug-jit.c.
83 (mono_debug_create_notification_function): Use two new functions
84 mono_debug_codegen_breakpoint() and mono_debug_codegen_ret()
85 instead of x86_breakpoint() and x86_ret().
87 Sat Mar 1 12:36:45 CET 2003 Paolo Molaro <lupus@ximian.com>
89 * jit.c: remove unnecessary assert when inlining.
91 2003-02-17 Martin Baulig <martin@ximian.com>
93 * jit.c (mono_jit_compile_method): Don't emit a `nop' at the start
96 2003-02-14 Patrik Torstensson
98 * x86.brg: Implemented CONV_OVF_[I|U]4 (freg), this fixes the issues
99 with the "checked" keyword. Closes bugs #33421 and #35280 (JIT not mint)
101 2003-02-14 Dietmar Maurer <dietmar@ximian.com>
103 * exception.c (mono_arch_find_jit_info): better way to handle
104 situations where we have no MonoJitInfo
106 2003-02-11 Zoltan Varga <vargaz@freemail.hu>
108 * trampoline.c (arch_create_jit_trampoline): This function should
109 allways return a trampoline for managed methods. Fixes bug #29859.
111 2003-02-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>
113 * debug.c: allocate debug->source_files. Fixes GLib-CRITICAL upon
116 2003-02-02 Martin Baulig <martin@ximian.com>
118 * debug.c (mono_debug_add_wrapper): Lookup the wrapper method in a
119 hash table; we need to provide the correct code_size.
121 2003-02-02 Martin Baulig <martin@ximian.com>
123 * jit.c (mono_jit_compile_method): Call mono_debug_add_wrapper()
124 to add the interncall to the symbol file.
126 * debug.c (mono_debug_add_wrapper): New public function.
128 2003-02-02 Martin Baulig <martin@ximian.com>
130 * debug.c (debug_update_il_offsets): Set the prologue end address
131 to the address of the first source line.
133 2003-01-31 Dietmar Maurer <dietmar@ximian.com>
135 * jit.c (mono_analyze_stack): use the wrapper signature if necessary
137 2003-01-31 Zoltan Varga <vargaz@freemail.hu>
139 * debug.c (mono_debug_open_image): dynamic assemblies have no debug
142 Thu Jan 30 11:07:06 CET 2003 Paolo Molaro <lupus@ximian.com>
144 * helper.c: handle MONO_TYPE_ARRAY as well.
146 2003-01-29 Dietmar Maurer <dietmar@ximian.com>
148 * jit.c (mono_analyze_stack): impl. CEE_MONO_LDNATIVEOBJ
149 (mono_analyze_stack): RETOBJ always returns native sized objects
151 2003-01-28 Zoltan Varga <vargaz@freemail.hu>
153 * x86.brg (mono_ldintftn): use <= instead of <, since the
154 interface_offsets array is max_interface_id + 1 long.
156 2003-01-28 Dietmar Maurer <dietmar@ximian.com>
158 * x86.brg (mono_ldintftn): fix from Zoltan: use max_interface_id
160 2003-01-27 Zoltan Varga <vargaz@freemail.hu>
162 * exception.c (ves_icall_get_trace): avoid crash if the exception is
165 * exception.c (ves_icall_get_trace): avoid crash on unmanaged frames.
167 2003-01-26 Martin Baulig <martin@ximian.com>
169 * debug.c (mono_debug_init): Take a boolean argument which
170 specifies whether we're running in the Mono Debugger.
172 2003-01-24 Martin Baulig <martin@ximian.com>
174 * debug.c (mono_debug_io_layer): Disable this on Windows.
176 2003-01-23 Dick Porter <dick@ximian.com>
178 * mono.c: Use mono_runtime_exec_managed_code() to run all managed
181 * jit.c: Changed thread start and attach callbacks to pass the
182 thread ID, not the MonoThread pointer. Arrange that managed code
183 execution will fail an assertion in the main thread, just to be
186 2003-01-22 Martin Baulig <martin@ximian.com>
188 * debug.c: Reverted Gonzalo's last change since it is wrong.
189 We're also using the debugging code on Windows, for instance the
190 stabs stuff when running in gdb. I hope this code still builds on
191 Windows; if not, we need to fix this.
192 Moved all the mono debugger support code into the debugger itself;
193 when debugging a managed application, the debugger new launches a
194 small unmanaged wrapper application which contains this stuff.
196 * debug.h (MonoDebuggerIOLayer): New public typedef; this is just
197 initialized to an array of function pointers to the io-layer
198 function; they don't seem to be public in the `libmono' library.
199 (mono_debugger_event): New public function. Sends the debugger an
200 event if we're running in the Mono Debugger and does nothing otherwise.
202 * mono.c: Don't initialize the Mono Debugger here.
204 * jit.c (mono_debug_insert_breakpoint): Removed, this isn't used anymore.
205 (mono_thread_start_cb, mono_thread_attach_cb): Call
206 mono_debugger_event() to send the debugger a callback.
208 2003-01-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
210 * debug.c: make all public symbols just dummy for windows.
212 2003-01-20 Miguel de Icaza <miguel@ximian.com>
214 * debug.c (initialize_debugger_support): ifdef out the call to
215 mono_debugger_init_thread_debug for the release.
217 Someone should look into why its not defined. I think the problem
218 is what Dick pointed out somewhere: code in io-layer is not
219 supposed to ever be used in Windows, so code for the debugger that
220 lives there must be moved elsewhere.
222 2003-01-19 Martin Baulig <martin@ximian.com>
224 * debug.c: Ok, this should now finally be working this time ....
226 2003-01-18 Martin Baulig <martin@ximian.com>
228 * debug.c (mono_debugger_jit_exec): Send the background thread a
229 SIGKILL before returning.
231 2003-01-17 Dietmar Maurer <dietmar@ximian.com>
233 * x86.brg: removed duplicated CONV_OVF_I4
235 2003-01-17 Martin Baulig <martin@ximian.com>
237 * debug.c: Don't use mono_once here. Reworked the API a bit to
238 use `mono_debug_' and `debug_' for the general debugging API and
239 `mono_debugger_' and `debugger_' for the Mono Debugger stuff.
241 2003-01-16 Martin Baulig <martin@ximian.com>
243 * debug.c (debugger_thread_func): We don't need to `raise
244 (SIGSTOP)' anymore; the thread manager already takes care of this.
246 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
248 * exception.c (arch_handle_exception): exclude runtime invoke
249 wrapper from the stack trace
251 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
252 (mono_thread_start_cb): save an additional LMF at thread start
254 2003-01-16 Martin Baulig <martin@ximian.com>
256 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
257 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
258 and the LinuxThreads port doesn't allow you to override the handler.
259 [FIXME: This avoids an assertion failure on startup, but there's
260 still an issue with thread termination.]
262 2003-01-16 Martin Baulig <martin@ximian.com>
264 * debug.c (debugger_thread_func): We don't need to `raise
265 (SIGSTOP)' anymore; the thread manager already takes care of this.
267 2003-01-16 Martin Baulig <martin@ximian.com>
269 * debug.c: Use the mono/io-layer functions here instead of gthread.
271 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
273 * jit.c (mono_jit_compile_method): make sure runtime_init is called
274 (mono_analyze_stack): make sure runtime_init is called
276 2003-01-14 Martin Baulig <martin@ximian.com>
278 * debug.c (debugger_update_symbol_file_table): Moved all the
279 functionality into debugger_update_symbol_file_table_internal();
280 the latter one will be called from the background thread while
281 already owning the lock. This'll allow us to step into
282 debugger_update_symbol_file_table() in the debugger and debug it.
284 2003-01-14 Martin Baulig <martin@ximian.com>
286 * Makefile.am: Link against gthread.
288 * jit.c: After realizing that mono-mutex doesn't work either
289 because it doesn't support recursive mutexes on FreeBSD, rewrote
290 the whole thread stuff to use gthread. This seems to fix this
291 weird deadlock in the debugger as well.
293 2003-01-12 Alp Toker <alp@atoker.com>
295 * exception.c: Typo fix: insinde -> inside
297 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
299 * exception.c (ves_icall_get_frame_info): skip one more frame and also
300 MONO_WRAPPER_RUNTIME_INVOKE wrappers
301 (x86_unwind_native_frame): disable unnecessary assertion
303 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
305 * exception.c (ves_icall_get_frame_info): fix bug 36382
307 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
309 * jit.c: handle wrapper_data in NEWOBJ/CALL.
311 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
313 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
315 2003-01-06 Martin Baulig <martin@ximian.com>
317 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
319 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
320 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
322 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
324 * debug.c: Move must_send_finished var declaration out of #if win32
325 block (this fixes the build on win32)
327 2003-01-05 Martin Baulig <martin@ximian.com>
329 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
330 this is used when we're running inside the Mono Debugger
331 (mono_debugger_wait): Put the waiting code into a function of its own.
333 * mono.c (main): Call mono_debugger_jit_exec() instead of
334 mono_jit_exec() if we're running inside the Mono Debugger.
336 2003-01-05 Martin Baulig <martin@ximian.com>
338 * debug.h (MonoDebugFormat): Added
339 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
340 we're running inside the Mono Debugger prior to the args parsing.
342 2003-01-04 Martin Baulig <martin@ximian.com>
344 * debug.c (release_symbol_file_table): Only call this if we're
345 actually modifying the symbol tables.
346 (mono_debug_open): Always set the `mono_debugger_class_init_func'
347 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
349 2003-01-03 Martin Baulig <martin@ximian.com>
351 * debug.c: Disable the mono debugger stuff on Windows.
353 2003-01-03 Martin Baulig <martin@ximian.com>
355 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
356 function. This is called from the breakpoint trampoline to signal
357 the debugger and wait until it has reload the symbol tables.
359 * trampoline.c (get_breakpoint_trampoline): Call the new
360 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
361 trampoline just before the breakpoint.
363 2002-12-31 Martin Baulig <martin@ximian.com>
365 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
366 field to point to the MonoGlobalSymbolTable.
368 2002-12-30 Martin Baulig <martin@ximian.com>
370 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
371 This variable now specifies that the symbol tables have been
372 modified after the last notification has been send. The debugger
373 uses this flag to check whether it needs to reload the symbol
375 (debugger_compile_method): Just send a notification to the
376 debugger, but don't set the modified flag. It may or may not be
377 set when the debugger gets the notification - depending on whether
378 the JIT compilation added a new method to the symbol tables.
380 2002-12-30 Martin Baulig <martin@ximian.com>
382 * debug.c (debugger_compile_method): This is a wrapper around
383 mono_compile_method() which always sends a notification to the
386 2002-12-30 Martin Baulig <martin@ximian.com>
388 * debug.c: Reload the symbol file table before sending the
389 notification event to the debugger.
390 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
392 2002-12-31 Martin Baulig <martin@ximian.com>
394 * debug.c: Propertly lock everything and avoid race conditions.
395 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
397 2002-12-31 Duncan Mak <duncan@ximian.com>
399 * debug.c (initialize_debugger_support): Fix build error by
400 declaring ret at the top of the function.
402 2002-12-30 Martin Baulig <martin@ximian.com>
404 * debug.c: When running under the mono debugger, create a special
405 debugger thread; always protect the symbol tables with a mutex.
407 2002-12-28 Martin Baulig <martin@ximian.com>
409 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
410 incremented each time one of the symbol tables is modified.
412 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
414 * jit.c: fix LDELEMA implementation here as well.
416 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
418 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
420 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
422 * jit.c: query the thread abort signal from the runtime.
424 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
426 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
428 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
430 * jit.c (mono_analyze_stack): call the utility function
431 mono_field_from_token to avoid code duplication.
433 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
435 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
437 * x86.brg (stmt): POP floating point stack correctly
439 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
441 * emit-x86.c (arch_emit_prologue): don't save caller saved
444 * exception.c (x86_unwind_native_frame): support exceptions inside
445 native code using gcc generated exception tables (-fexception).
447 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
449 * exception.c: include some code from Zoltan Varga, but modified
452 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
454 * exception.c: massive code cleanups. The code is still
455 architecture dependent, but it should be now possible to reuse the
456 complex parts for other architecture.
458 2002-11-15 Dick Porter <dick@ximian.com>
460 * jit.c: Pass the attach callback to mono_runtime_init().
462 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
464 * jit.c: display the domain name in trace output.
466 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
468 * x86.brg (reg): fix bug #2721
470 * jit.c (mono_runtime_install_handlers): impl.
472 2002-10-17 Martin Baulig <martin@gnome.org>
474 * debug.c (mono_debug_add_method): Make this actually work if we don't
475 have any lifetime information.
477 2002-10-15 Martin Baulig <martin@gnome.org>
479 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
481 * debug.c (generate_line_number): Small fix to make this actually
482 work for more complex things.
484 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
486 * x86.brg (freg): use fprem instead of fprem1
488 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
490 * jit.c (ves_array_element_address): added check for out of range index
491 (mono_analyze_stack): added fix for bug #31654
493 2002-10-01 Martin Baulig <martin@gnome.org>
495 * debug.c: Don't create an .il file for the dynamic symbol file.
497 2002-10-01 Martin Baulig <martin@gnome.org>
499 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
501 2002-09-27 Martin Baulig <martin@gnome.org>
503 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
505 2002-09-27 Dick Porter <dick@ximian.com>
507 * mono.c: Tell glib what the program name is, by passing it the
508 name of the managed file we're executing
510 2002-09-26 Martin Baulig <martin@gnome.org>
512 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
513 trampoline into the vtable, also use it for non-virtual methods,
514 remove the breakpoint when done.
516 2002-09-26 Martin Baulig <martin@gnome.org>
518 * debug.c (debug_load_method_lines): Block SIGCHLD while running
521 2002-09-26 Martin Baulig <martin@gnome.org>
523 * debug.c: Reworked the whole debugging stuff. We have now one
524 single `mono_debug_handle' which keeps a hashtable of
525 `AssemblyDebugInfo's (which may have different debugging formats).
526 The AssemblyDebugInfo is now created when the assembly is loaded,
527 but never when adding a class/type.
529 * mono.c: Initialize debugging stuff after corlib and the assembly
532 2002-09-25 Martin Baulig <martin@gnome.org>
534 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
535 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
537 (DebugMethodInfo): Removed `line_numbers'.
539 * debug.c: Reworked the line number generation; we're now using
540 the MonoDebugLineNumberEntry try for all debugging formats. This
541 type also includes the line number and IL offset, this allows the
542 JIT to produce better line number info: we only emit line number
543 information for source lines which actually have code.
545 2002-09-25 Martin Baulig <martin@gnome.org>
547 * debug.h: Removed external declaration of all functions which
548 should only be called from the Mono Debugger and also made them
549 static. Since the debugger gets their address from the
550 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
553 2002-09-25 Martin Baulig <martin@gnome.org>
555 Improved breakpoint support, we can now dynamically insert and
556 remove breakpoints at runtime and when called from withing the
557 Mono Debugger, we're using a special breakpoint trampoline.
559 * debug.h (mono_method_has_breakpoint): New method to check
560 whether to insert a breakpoint for a method.
561 (mono_insert_breakpoint): New method to insert a breakpoint.
562 (mono_insert_breakpoint_full): New method to insert a breakpoint,
563 takes a MonoMethodDesc.
564 (mono_remove_breakpoint): New method to remove a breakpoint.
566 * debug.c (mono_debugger_insert_breakpoint): New function for the
567 debugger. Should only be called from the debugger.
568 (mono_debugger_remove_breakpoint): Likewise.
570 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
572 * trampoline.c (get_breakpoint_trampoline): New static function to
573 create a special breakpoint trampoline for the debugger.
574 (x86_magic_trampoline): If we're running inside the Mono Debugger
575 and a breakpoint was requested for the method, generate a special
576 breakpoint trampoline.
578 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
579 to insert a breakpoint.
580 (mono_debug_last_breakpoint_address): Removed.
581 (match_debug_method): Removed, use mono_method_has_breakpoint().
583 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
585 * jit.c: reorder mono_runtime_cleanup () call since it needs the
586 engine still fully working.
588 2002-09-24 Martin Baulig <martin@gnome.org>
590 * debug.c (mono_debug_open): When we're invoked from inside the

666 `mono_symfile' to `symfile'.
668 * debug.c (mono_debug_open): Replaced the assembly argument with a
669 file name argument; you can now call this before loading the assembly.
670 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
671 we now use MonoSymbolFileLineNumberEntry's and a separate address array
672 instead; splitted out all MonoSymbolFileLineNumberEntry code into
673 debug_generate_il_offsets() and debug_update_il_offsets().
674 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's

729 symbol file for IL files on-the-fly. In this case, we also need to create
730 the IL files and parse them.

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

1210 a `MonoAssembly *' argument instead of a `char *filename' one. Also added
1211 `const char **args' argument.
1213 * mono.c (mono_jit_assembly): Renamed to mono_jit_compile_image(), added
1214 `int verbose' argument and made it public.
1215 (mono_jit_compile_class): New public function, moved the code to compile
1216 all methods in a class here from main().
1217 (--compile): The argument can now also be an image (in `@imagename' format).
1218 Updated documentation for this command line argument.

1254 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
1255 file for all assemblies. Currently, the JIT doesn't put all methods
1256 from a single assembly into a continuous region of memory. We were
1257 previously creating valid DWARF 2 files for this, but unfortunately
1258 GDB's symbol tables get messed up when it reads more than one such file.
1260 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',
1261 `next_idx', `methods', `type_hash', `source_files' and `format'
1262 into the MonoDebugHandle.

1354 SHL/SHR because the tree allocator can fail otherwise
1356 * exception.c (arch_handle_exception): EIP now points to the call
1357 instruction, not to the instruction after the call. This fixes the
1358 bug reported by Linus Upson (tests/exception8.cs)

1806 2002-03-23 Martin Baulig <martin@gnome.org>
1808 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1809 to do it before the X86_CMP.
1810 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1811 (reg: CLT (lreg, lreg)): Likewise.

1925 (mono_debug_open_file): Added MonoDebugFormat argument.
1926 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1927 this function from GDB. It's now safe to call this function multiple times;
1928 it'll always write a complete debugging file.
1930 * debug.c: Splitted this file into a general part which remains in this file
1931 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1932 All public functions now call a corresponding format specific function.
1934 * debug.c: The following changes are private to debug.c:
1935 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1936 (record_line_number, debug_generate_method_lines): New private functions.
1937 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1938 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1939 mono_debug_open_assembly_dwarf2).
1940 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1941 now safe to call this function multiple times.
1942 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1943 returns an unique index for this type. It's used to ensure that we only write
1944 each class once to the debugging file.
1945 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1946 data structure, but don't directly write to the debugging file. This is done
1947 later from mono_debug_write_assembly().
1949 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1950 debugging output. Call mono_debug_close() on cleanup if necessary.

1954 * debug-private.h: New private header file.
1956 * debug-stabs.c: Added the stabs type generation stuff which was
1957 previously in debug.c.

1960 only writing this most basic types to the dwarf file, but this will
1963 2002-03-13 Martin Baulig <martin@gnome.org>
1965 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1966 debugging code. They're now in CVS, but not yet used anywhere.
1968 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1970 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*

1976 * jit.c: verify that corlib and runtime are in sync.
1978 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1980 * emit-x86.c, jit.c: use the debug-helpers facilities to
1981 describe and match a method when debugging.
1983 2002-03-10 Martin Baulig <martin@gnome.org>
1985 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1986 output, put a nop instruction at the start of all functions so that
1987 the adresses won't change when using --debug.
1989 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1990 the bytecode area, stabs needs a line number in the .il file. Use the
1991 new info->moffsets to get the line number.
1992 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1993 `moffsets' is an array of `total_lines' fields (total number of lines
1994 in the .il file); for each line in the .il field, this array contains
1995 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1996 of a method and 0 otherwise.
1997 (debug_load_method_lines): Read the whole .il file and initialize the
1998 info->moffsets field.
2000 2002-03-09 Martin Baulig <martin@gnome.org>
2002 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
2003 the unnecessary CDQ instruction.
