1 2003-01-24 Martin Baulig <martin@ximian.com>
3 * debug.c (mono_debug_io_layer): Disable this on Windows.
5 2003-01-23 Dick Porter <dick@ximian.com>
7 * mono.c: Use mono_runtime_exec_managed_code() to run all managed
10 * jit.c: Changed thread start and attach callbacks to pass the
11 thread ID, not the MonoThread pointer. Arrange that managed code
12 execution will fail an assertion in the main thread, just to be
15 2003-01-22 Martin Baulig <martin@ximian.com>
17 * debug.c: Reverted Gonzalo's last change since it is wrong.
18 We're also using the debugging code on Windows, for instance the
19 stabs stuff when running in gdb. I hope this code still builds on
20 Windows; if not, we need to fix this.
21 Moved all the mono debugger support code into the debugger itself;
22 when debugging a managed application, the debugger new launches a
23 small unmanaged wrapper application which contains this stuff.
25 * debug.h (MonoDebuggerIOLayer): New public typedef; this is just
26 initialized to an array of function pointers to the io-layer
27 function; they don't seem to be public in the `libmono' library.
28 (mono_debugger_event): New public function. Sends the debugger an
29 event if we're running in the Mono Debugger and does nothing otherwise.
31 * mono.c: Don't initialize the Mono Debugger here.
33 * jit.c (mono_debug_insert_breakpoint): Removed, this isn't used anymore.
34 (mono_thread_start_cb, mono_thread_attach_cb): Call
35 mono_debugger_event() to send the debugger a callback.
37 2003-01-20 Gonzalo Paniagua Javier <gonzalo@ximian.com>
39 * debug.c: make all public symbols just dummy for windows.
41 2003-01-20 Miguel de Icaza <miguel@ximian.com>
43 * debug.c (initialize_debugger_support): ifdef out the call to
44 mono_debugger_init_thread_debug for the release.
46 Someone should look into why its not defined. I think the problem
47 is what Dick pointed out somewhere: code in io-layer is not
48 supposed to ever be used in Windows, so code for the debugger that
49 lives there must be moved elsewhere.
51 2003-01-19 Martin Baulig <martin@ximian.com>
53 * debug.c: Ok, this should now finally be working this time ....
55 2003-01-18 Martin Baulig <martin@ximian.com>
57 * debug.c (mono_debugger_jit_exec): Send the background thread a
58 SIGKILL before returning.
60 2003-01-17 Dietmar Maurer <dietmar@ximian.com>
62 * x86.brg: removed duplicated CONV_OVF_I4
64 2003-01-17 Martin Baulig <martin@ximian.com>
66 * debug.c: Don't use mono_once here. Reworked the API a bit to
67 use `mono_debug_' and `debug_' for the general debugging API and
68 `mono_debugger_' and `debugger_' for the Mono Debugger stuff.
70 2003-01-16 Martin Baulig <martin@ximian.com>
72 * debug.c (debugger_thread_func): We don't need to `raise
73 (SIGSTOP)' anymore; the thread manager already takes care of this.
75 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
77 * exception.c (arch_handle_exception): exclude runtime invoke
78 wrapper from the stack trace
80 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
81 (mono_thread_start_cb): save an additional LMF at thread start
83 2003-01-16 Martin Baulig <martin@ximian.com>
85 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
86 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
87 and the LinuxThreads port doesn't allow you to override the handler.
88 [FIXME: This avoids an assertion failure on startup, but there's
89 still an issue with thread termination.]
91 2003-01-16 Martin Baulig <martin@ximian.com>
93 * debug.c (debugger_thread_func): We don't need to `raise
94 (SIGSTOP)' anymore; the thread manager already takes care of this.
96 2003-01-16 Martin Baulig <martin@ximian.com>
98 * debug.c: Use the mono/io-layer functions here instead of gthread.
100 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
102 * jit.c (mono_jit_compile_method): make sure runtime_init is called
103 (mono_analyze_stack): make sure runtime_init is called
105 2003-01-14 Martin Baulig <martin@ximian.com>
107 * debug.c (debugger_update_symbol_file_table): Moved all the
108 functionality into debugger_update_symbol_file_table_internal();
109 the latter one will be called from the background thread while
110 already owning the lock. This'll allow us to step into
111 debugger_update_symbol_file_table() in the debugger and debug it.
113 2003-01-14 Martin Baulig <martin@ximian.com>
115 * Makefile.am: Link against gthread.
117 * jit.c: After realizing that mono-mutex doesn't work either
118 because it doesn't support recursive mutexes on FreeBSD, rewrote
119 the whole thread stuff to use gthread. This seems to fix this
120 weird deadlock in the debugger as well.
122 2003-01-12 Alp Toker <alp@atoker.com>
124 * exception.c: Typo fix: insinde -> inside
126 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
128 * exception.c (ves_icall_get_frame_info): skip one more frame and also
129 MONO_WRAPPER_RUNTIME_INVOKE wrappers
130 (x86_unwind_native_frame): disable unnecessary assertion
132 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
134 * exception.c (ves_icall_get_frame_info): fix bug 36382
136 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
138 * jit.c: handle wrapper_data in NEWOBJ/CALL.
140 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
142 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
144 2003-01-06 Martin Baulig <martin@ximian.com>
146 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
148 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
149 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
151 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
153 * debug.c: Move must_send_finished var declaration out of #if win32
154 block (this fixes the build on win32)
156 2003-01-05 Martin Baulig <martin@ximian.com>
158 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
159 this is used when we're running inside the Mono Debugger
160 (mono_debugger_wait): Put the waiting code into a function of its own.
162 * mono.c (main): Call mono_debugger_jit_exec() instead of
163 mono_jit_exec() if we're running inside the Mono Debugger.
165 2003-01-05 Martin Baulig <martin@ximian.com>
167 * debug.h (MonoDebugFormat): Added
168 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
169 we're running inside the Mono Debugger prior to the args parsing.
171 2003-01-04 Martin Baulig <martin@ximian.com>
173 * debug.c (release_symbol_file_table): Only call this if we're
174 actually modifying the symbol tables.
175 (mono_debug_open): Always set the `mono_debugger_class_init_func'
176 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
178 2003-01-03 Martin Baulig <martin@ximian.com>
180 * debug.c: Disable the mono debugger stuff on Windows.
182 2003-01-03 Martin Baulig <martin@ximian.com>
184 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
185 function. This is called from the breakpoint trampoline to signal
186 the debugger and wait until it has reload the symbol tables.
188 * trampoline.c (get_breakpoint_trampoline): Call the new
189 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
190 trampoline just before the breakpoint.
192 2002-12-31 Martin Baulig <martin@ximian.com>
194 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
195 field to point to the MonoGlobalSymbolTable.
197 2002-12-30 Martin Baulig <martin@ximian.com>
199 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
200 This variable now specifies that the symbol tables have been
201 modified after the last notification has been send. The debugger
202 uses this flag to check whether it needs to reload the symbol
204 (debugger_compile_method): Just send a notification to the
205 debugger, but don't set the modified flag. It may or may not be
206 set when the debugger gets the notification - depending on whether
207 the JIT compilation added a new method to the symbol tables.
209 2002-12-30 Martin Baulig <martin@ximian.com>
211 * debug.c (debugger_compile_method): This is a wrapper around
212 mono_compile_method() which always sends a notification to the
215 2002-12-30 Martin Baulig <martin@ximian.com>
217 * debug.c: Reload the symbol file table before sending the
218 notification event to the debugger.
219 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
221 2002-12-31 Martin Baulig <martin@ximian.com>
223 * debug.c: Propertly lock everything and avoid race conditions.
224 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
226 2002-12-31 Duncan Mak <duncan@ximian.com>
228 * debug.c (initialize_debugger_support): Fix build error by
229 declaring ret at the top of the function.
231 2002-12-30 Martin Baulig <martin@ximian.com>
233 * debug.c: When running under the mono debugger, create a special
234 debugger thread; always protect the symbol tables with a mutex.
236 2002-12-28 Martin Baulig <martin@ximian.com>
238 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
239 incremented each time one of the symbol tables is modified.
241 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
243 * jit.c: fix LDELEMA implementation here as well.
245 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
247 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
249 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
251 * jit.c: query the thread abort signal from the runtime.
253 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
255 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
257 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
259 * jit.c (mono_analyze_stack): call the utility function
260 mono_field_from_token to avoid code duplication.
262 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
264 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
266 * x86.brg (stmt): POP floating point stack correctly
268 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
270 * emit-x86.c (arch_emit_prologue): don't save caller saved
273 * exception.c (x86_unwind_native_frame): support exceptions inside
274 native code using gcc generated exception tables (-fexception).
276 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
278 * exception.c: include some code from Zoltan Varga, but modified
281 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
283 * exception.c: massive code cleanups. The code is still
284 architecture dependent, but it should be now possible to reuse the
285 complex parts for other architecture.
287 2002-11-15 Dick Porter <dick@ximian.com>
289 * jit.c: Pass the attach callback to mono_runtime_init().
291 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
293 * jit.c: display the domain name in trace output.
295 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
297 * x86.brg (reg): fix bug #2721
299 * jit.c (mono_runtime_install_handlers): impl.
301 2002-10-17 Martin Baulig <martin@gnome.org>
303 * debug.c (mono_debug_add_method): Make this actually work if we don't
304 have any lifetime information.
306 2002-10-15 Martin Baulig <martin@gnome.org>
308 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
310 * debug.c (generate_line_number): Small fix to make this actually
311 work for more complex things.
313 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
315 * x86.brg (freg): use fprem instead of fprem1
317 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
319 * jit.c (ves_array_element_address): added check for out of range index
320 (mono_analyze_stack): added fix for bug #31654
322 2002-10-01 Martin Baulig <martin@gnome.org>
324 * debug.c: Don't create an .il file for the dynamic symbol file.
326 2002-10-01 Martin Baulig <martin@gnome.org>
328 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
330 2002-09-27 Martin Baulig <martin@gnome.org>
332 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
334 2002-09-27 Dick Porter <dick@ximian.com>
336 * mono.c: Tell glib what the program name is, by passing it the
337 name of the managed file we're executing
339 2002-09-26 Martin Baulig <martin@gnome.org>
341 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
342 trampoline into the vtable, also use it for non-virtual methods,
343 remove the breakpoint when done.
345 2002-09-26 Martin Baulig <martin@gnome.org>
347 * debug.c (debug_load_method_lines): Block SIGCHLD while running
350 2002-09-26 Martin Baulig <martin@gnome.org>
352 * debug.c: Reworked the whole debugging stuff. We have now one
353 single `mono_debug_handle' which keeps a hashtable of
354 `AssemblyDebugInfo's (which may have different debugging formats).
355 The AssemblyDebugInfo is now created when the assembly is loaded,
356 but never when adding a class/type.
358 * mono.c: Initialize debugging stuff after corlib and the assembly
361 2002-09-25 Martin Baulig <martin@gnome.org>
363 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
364 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
366 (DebugMethodInfo): Removed `line_numbers'.
368 * debug.c: Reworked the line number generation; we're now using
369 the MonoDebugLineNumberEntry try for all debugging formats. This
370 type also includes the line number and IL offset, this allows the
371 JIT to produce better line number info: we only emit line number
372 information for source lines which actually have code.
374 2002-09-25 Martin Baulig <martin@gnome.org>
376 * debug.h: Removed external declaration of all functions which
377 should only be called from the Mono Debugger and also made them
378 static. Since the debugger gets their address from the
379 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
382 2002-09-25 Martin Baulig <martin@gnome.org>
384 Improved breakpoint support, we can now dynamically insert and
385 remove breakpoints at runtime and when called from withing the
386 Mono Debugger, we're using a special breakpoint trampoline.
388 * debug.h (mono_method_has_breakpoint): New method to check
389 whether to insert a breakpoint for a method.
390 (mono_insert_breakpoint): New method to insert a breakpoint.
391 (mono_insert_breakpoint_full): New method to insert a breakpoint,
392 takes a MonoMethodDesc.
393 (mono_remove_breakpoint): New method to remove a breakpoint.
395 * debug.c (mono_debugger_insert_breakpoint): New function for the
396 debugger. Should only be called from the debugger.
397 (mono_debugger_remove_breakpoint): Likewise.
399 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
401 * trampoline.c (get_breakpoint_trampoline): New static function to
402 create a special breakpoint trampoline for the debugger.
403 (x86_magic_trampoline): If we're running inside the Mono Debugger
404 and a breakpoint was requested for the method, generate a special
405 breakpoint trampoline.
407 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
408 to insert a breakpoint.
409 (mono_debug_last_breakpoint_address): Removed.
410 (match_debug_method): Removed, use mono_method_has_breakpoint().
412 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
414 * jit.c: reorder mono_runtime_cleanup () call since it needs the
415 engine still fully working.
417 2002-09-24 Martin Baulig <martin@gnome.org>
419 * debug.c (mono_debug_open): When we're invoked from inside the
420 Mono Debugger, set mono_debugger_class_init_func (exported in
421 metadata/class.c) to mono_add_type().
422 (mono_add_type): Call mono_debug_symfile_add_type().
424 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
426 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
427 Run finalize on domain cleanup.
428 * mono.c: call setlocale ().
429 * trampoline.c: clearer error message for invalid trampoline.
431 2002-09-21 Martin Baulig <martin@gnome.org>
433 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
434 instead of writing a byte blob.
435 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
436 (mono_debug_add_method): Incrementally add the new method to the symbol
439 * exception.c (arch_handle_exception): If we have debugging support,
440 call mono_debugger_update_symbol_file_table () as well.
442 2002-09-20 Martin Baulig <martin@gnome.org>
444 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
445 the size of the variable.
447 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
449 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
450 iterations if we visit blocks in reverse order.
452 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
454 * jit.c (mono_analyze_stack): cleaup of the array code
456 * exception.c: added patch from Julio Merno to fix bug #30048
458 * jit.c (mono_analyze_stack): code cleanup, fix bug #29365
460 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
462 * x86.brg (LDELEMA): use x86_lea
464 2002-09-06 Martin Baulig <martin@gnome.org>
466 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
467 If you were getting random crashes when using the JIT with debugging
468 turned on, this fixes it.
470 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
472 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
474 2002-09-05 Martin Baulig <martin@gnome.org>
476 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
477 which is read by the debugger.
479 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>
481 * Makefile.am: link libmono directly into mono. Use a ld script
482 to reduce exported symbols.
484 2002-09-03 Martin Baulig <martin@gnome.org>
486 * debug.c (free_method_info): Make this actually work.
488 2002-09-03 Martin Baulig <martin@gnome.org>
490 * debug.h (MonoDebugFormat): Killed MONO_DEBUG_FORMAT_DWARF2_PLUS.
491 * debug-dwarf2-plus.c: Removed.
493 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
494 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
495 `mono_symfile' to `symfile'.
497 * debug.c (mono_debug_open): Replaced the assembly argument with a
498 file name argument; you can now call this before loading the assembly.
499 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
500 we now use MonoSymbolFileLineNumberEntry's and a separate address array
501 instead; splitted out all MonoSymbolFileLineNumberEntry code into
502 debug_generate_il_offsets() and debug_update_il_offsets().
503 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
504 created when reading the symbol file or from debug_load_method_lines().
505 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
507 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before
508 looking up an address.
510 * debug.c: Don't create the .il files for MONO_DEBUG_FORMAT_MONO.
512 * mono.c (main): Initialize debugging before loading the first assembly.
514 2002-08-28 Dick Porter <dick@ximian.com>
516 * mono.c: mono_set_rootdir() doesnt take any args now
518 * Makefile.am: Export HOST_CC for w32 builds
520 2002-08-28 Dietmar Maurer <dietmar@ximian.com>
522 * jit.c (mono_store_tree): only allocate vars if really necessary
524 2002-08-27 Martin Baulig <martin@gnome.org>
526 * debug.c: The mono symbol file is installed together with the assembly
527 it belongs to and it's used on a per-image basis.
529 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
531 * mono.c: don't use the cil-coff header outside of the loader.
533 2002-08-27 Martin Baulig <martin@gnome.org>
535 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
536 to use global variables for this since they're stored in a core file.
537 (mono_debugger_symbol_file_table_generation): New global variable.
538 (mono_debugger_symbol_file_table): New global variable.
539 (mono_debugger_update_symbol_file_table): New global function to update
540 the symbol file table.
542 2002-08-27 Martin Baulig <martin@gnome.org>
544 * trampoline.c (mono_generic_trampoline_code): New global variable.
545 (arch_create_jit_trampoline): Use the new global variable to store the
546 generic trampoline code instead of using a static one. This allows the
547 debugger to access this variable to check whether a method is a trampoline.
549 * debug.h (mono_generic_trampoline_code): Added external declaration.
551 2002-08-27 Martin Baulig <martin@gnome.org>
553 * debug.c (MonoDebugHandle): Moved the method hash into the
554 AssemblyDebugInfo struct since we need to use a separate hash for each
557 * debug.c: Added special undocumented command line argument to create a
558 symbol file for IL files on-the-fly. In this case, we also need to create
559 the IL files and parse them.
560 (mono_debugger_internal_get_symbol_files): Return something more reasonable.
562 2002-08-26 Martin Baulig <martin@gnome.org>
564 * debug.c (mono_debugger_internal_free_symbol_files): New function.
565 (mono_debugger_internal_symbol_files_changed): New global variable.
567 2002-08-24 Martin Baulig <martin@gnome.org>
569 * debug.c (mono_debugger_internal_get_symbol_files): New function.
571 2002-08-24 Martin Baulig <martin@gnome.org>
573 * debug.c (mono_debug_write_symbols): Added support for the new
576 * mono.c (main): The `--debug' argument now knows about a new
577 debugging format `mono' which will be used to display source lines

1727 2002-03-16 Martin Baulig <martin@gnome.org>
1729 * debug-dwarf2.c: Added support for enums.
1731 2002-03-15 Martin Baulig <martin@gnome.org>

1752 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1754 (mono_debug_open_file): Added MonoDebugFormat argument.
1755 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1756 this function from GDB. It's now safe to call this function multiple times;
1757 it'll always write a complete debugging file.
1759 * debug.c: Splitted this file into a general part which remains in this file
1760 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1761 All public functions now call a corresponding format specific function.
1763 * debug.c: The following changes are private to debug.c:
1764 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1765 (record_line_number, debug_generate_method_lines): New private functions.
1766 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1767 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1768 mono_debug_open_assembly_dwarf2).
1769 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1770 now safe to call this function multiple times.
1771 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1772 returns an unique index for this type. It's used to ensure that we only write
1773 each class once to the debugging file.
1774 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1775 data structure, but don't directly write to the debugging file. This is done
1776 later from mono_debug_write_assembly().
1778 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1779 debugging output. Call mono_debug_close() on cleanup if necessary.
1781 2002-03-14 Martin Baulig <martin@gnome.org>
1783 * debug-private.h: New private header file.
1785 * debug-stabs.c: Added the stabs type generation stuff which was
1786 previously in debug.c.
1788 * debug-dwarf.c: Started to implement type support. We're currently
1789 only writing this most basic types to the dwarf file, but this will
1792 2002-03-13 Martin Baulig <martin@gnome.org>
1794 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1795 debugging code. They're now in CVS, but not yet used anywhere.
1797 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1799 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1800 macros, included new delegate code from Daniel Stodden.
1803 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1805 * jit.c: verify that corlib and runtime are in sync.
1807 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1809 * emit-x86.c, jit.c: use the debug-helpers facilities to
1810 describe and match a method when debugging.
1812 2002-03-10 Martin Baulig <martin@gnome.org>
1814 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1815 output, put a nop instruction at the start of all functions so that
1816 the adresses won't change when using --debug.
1818 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1819 the bytecode area, stabs needs a line number in the .il file. Use the
1820 new info->moffsets to get the line number.
1821 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1822 `moffsets' is an array of `total_lines' fields (total number of lines
1823 in the .il file); for each line in the .il field, this array contains
1824 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1825 of a method and 0 otherwise.
1826 (debug_load_method_lines): Read the whole .il file and initialize the
1827 info->moffsets field.
1829 2002-03-09 Martin Baulig <martin@gnome.org>
1831 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1832 the unnecessary CDQ instruction.
1834 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
