1 2003-01-16 Martin Baulig <martin@ximian.com>
3 * debug.c (debugger_thread_func): We don't need to `raise
4 (SIGSTOP)' anymore; the thread manager already takes care of this.
6 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
8 * exception.c (arch_handle_exception): exclude runtime invoke
9 wrapper from the stack trace
11 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
12 (mono_thread_start_cb): save an additional LMF at thread start
14 2003-01-16 Martin Baulig <martin@ximian.com>
16 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
17 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
18 and the LinuxThreads port doesn't allow you to override the handler.
19 [FIXME: This avoids an assertion failure on startup, but there's
20 still an issue with thread termination.]
22 2003-01-16 Martin Baulig <martin@ximian.com>
24 * debug.c (debugger_thread_func): We don't need to `raise
25 (SIGSTOP)' anymore; the thread manager already takes care of this.
27 2003-01-16 Martin Baulig <martin@ximian.com>
29 * debug.c: Use the mono/io-layer functions here instead of gthread.
31 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
33 * jit.c (mono_jit_compile_method): make sure runtime_init is called
34 (mono_analyze_stack): make sure runtime_init is called
36 2003-01-14 Martin Baulig <martin@ximian.com>
38 * debug.c (debugger_update_symbol_file_table): Moved all the
39 functionality into debugger_update_symbol_file_table_internal();
40 the latter one will be called from the background thread while
41 already owning the lock. This'll allow us to step into
42 debugger_update_symbol_file_table() in the debugger and debug it.
44 2003-01-14 Martin Baulig <martin@ximian.com>
46 * Makefile.am: Link against gthread.
48 * jit.c: After realizing that mono-mutex doesn't work either
49 because it doesn't support recursive mutexes on FreeBSD, rewrote
50 the whole thread stuff to use gthread. This seems to fix this
51 weird deadlock in the debugger as well.
53 2003-01-12 Alp Toker <alp@atoker.com>
55 * exception.c: Typo fix: insinde -> inside
57 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
59 * exception.c (ves_icall_get_frame_info): skip one more frame and also
60 MONO_WRAPPER_RUNTIME_INVOKE wrappers
61 (x86_unwind_native_frame): disable unnecessary assertion
63 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
65 * exception.c (ves_icall_get_frame_info): fix bug 36382
67 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
69 * jit.c: handle wrapper_data in NEWOBJ/CALL.
71 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
73 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
75 2003-01-06 Martin Baulig <martin@ximian.com>
77 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
79 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
80 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
82 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
84 * debug.c: Move must_send_finished var declaration out of #if win32
85 block (this fixes the build on win32)
87 2003-01-05 Martin Baulig <martin@ximian.com>
89 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
90 this is used when we're running inside the Mono Debugger
91 (mono_debugger_wait): Put the waiting code into a function of its own.
93 * mono.c (main): Call mono_debugger_jit_exec() instead of
94 mono_jit_exec() if we're running inside the Mono Debugger.
96 2003-01-05 Martin Baulig <martin@ximian.com>
98 * debug.h (MonoDebugFormat): Added
99 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
100 we're running inside the Mono Debugger prior to the args parsing.
102 2003-01-04 Martin Baulig <martin@ximian.com>
104 * debug.c (release_symbol_file_table): Only call this if we're
105 actually modifying the symbol tables.
106 (mono_debug_open): Always set the `mono_debugger_class_init_func'
107 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
109 2003-01-03 Martin Baulig <martin@ximian.com>
111 * debug.c: Disable the mono debugger stuff on Windows.
113 2003-01-03 Martin Baulig <martin@ximian.com>
115 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
116 function. This is called from the breakpoint trampoline to signal
117 the debugger and wait until it has reload the symbol tables.
119 * trampoline.c (get_breakpoint_trampoline): Call the new
120 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
121 trampoline just before the breakpoint.
123 2002-12-31 Martin Baulig <martin@ximian.com>
125 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
126 field to point to the MonoGlobalSymbolTable.
128 2002-12-30 Martin Baulig <martin@ximian.com>
130 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
131 This variable now specifies that the symbol tables have been
132 modified after the last notification has been send. The debugger
133 uses this flag to check whether it needs to reload the symbol
135 (debugger_compile_method): Just send a notification to the
136 debugger, but don't set the modified flag. It may or may not be
137 set when the debugger gets the notification - depending on whether
138 the JIT compilation added a new method to the symbol tables.
140 2002-12-30 Martin Baulig <martin@ximian.com>
142 * debug.c (debugger_compile_method): This is a wrapper around
143 mono_compile_method() which always sends a notification to the
146 2002-12-30 Martin Baulig <martin@ximian.com>
148 * debug.c: Reload the symbol file table before sending the
149 notification event to the debugger.
150 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
152 2002-12-31 Martin Baulig <martin@ximian.com>
154 * debug.c: Propertly lock everything and avoid race conditions.
155 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
157 2002-12-31 Duncan Mak <duncan@ximian.com>
159 * debug.c (initialize_debugger_support): Fix build error by
160 declaring ret at the top of the function.
162 2002-12-30 Martin Baulig <martin@ximian.com>
164 * debug.c: When running under the mono debugger, create a special
165 debugger thread; always protect the symbol tables with a mutex.
167 2002-12-28 Martin Baulig <martin@ximian.com>
169 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
170 incremented each time one of the symbol tables is modified.
172 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
174 * jit.c: fix LDELEMA implementation here as well.
176 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
178 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
180 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
182 * jit.c: query the thread abort signal from the runtime.
184 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
186 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
188 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
190 * jit.c (mono_analyze_stack): call the utility function
191 mono_field_from_token to avoid code duplication.
193 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
195 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
197 * x86.brg (stmt): POP floating point stack correctly
199 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
201 * emit-x86.c (arch_emit_prologue): don't save caller saved
204 * exception.c (x86_unwind_native_frame): support exceptions inside
205 native code using gcc generated exception tables (-fexception).
207 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
209 * exception.c: include some code from Zoltan Varga, but modified
212 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
214 * exception.c: massive code cleanups. The code is still
215 architecture dependent, but it should be now possible to reuse the
216 complex parts for other architecture.
218 2002-11-15 Dick Porter <dick@ximian.com>
220 * jit.c: Pass the attach callback to mono_runtime_init().
222 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
224 * jit.c: display the domain name in trace output.
226 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
228 * x86.brg (reg): fix bug #2721
230 * jit.c (mono_runtime_install_handlers): impl.
232 2002-10-17 Martin Baulig <martin@gnome.org>
234 * debug.c (mono_debug_add_method): Make this actually work if we don't
235 have any lifetime information.
237 2002-10-15 Martin Baulig <martin@gnome.org>
239 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
241 * debug.c (generate_line_number): Small fix to make this actually
242 work for more complex things.
244 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
246 * x86.brg (freg): use fprem instead of fprem1
248 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
250 * jit.c (ves_array_element_address): added check for out of range index
251 (mono_analyze_stack): added fix for bug #31654
253 2002-10-01 Martin Baulig <martin@gnome.org>
255 * debug.c: Don't create an .il file for the dynamic symbol file.
257 2002-10-01 Martin Baulig <martin@gnome.org>
259 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
261 2002-09-27 Martin Baulig <martin@gnome.org>
263 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
265 2002-09-27 Dick Porter <dick@ximian.com>
267 * mono.c: Tell glib what the program name is, by passing it the
268 name of the managed file we're executing
270 2002-09-26 Martin Baulig <martin@gnome.org>
272 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
273 trampoline into the vtable, also use it for non-virtual methods,
274 remove the breakpoint when done.
276 2002-09-26 Martin Baulig <martin@gnome.org>
278 * debug.c (debug_load_method_lines): Block SIGCHLD while running
281 2002-09-26 Martin Baulig <martin@gnome.org>
283 * debug.c: Reworked the whole debugging stuff. We have now one
284 single `mono_debug_handle' which keeps a hashtable of
285 `AssemblyDebugInfo's (which may have different debugging formats).
286 The AssemblyDebugInfo is now created when the assembly is loaded,
287 but never when adding a class/type.
289 * mono.c: Initialize debugging stuff after corlib and the assembly
292 2002-09-25 Martin Baulig <martin@gnome.org>
294 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
295 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
297 (DebugMethodInfo): Removed `line_numbers'.
299 * debug.c: Reworked the line number generation; we're now using
300 the MonoDebugLineNumberEntry try for all debugging formats. This
301 type also includes the line number and IL offset, this allows the
302 JIT to produce better line number info: we only emit line number
303 information for source lines which actually have code.
305 2002-09-25 Martin Baulig <martin@gnome.org>
307 * debug.h: Removed external declaration of all functions which
308 should only be called from the Mono Debugger and also made them
309 static. Since the debugger gets their address from the
310 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
313 2002-09-25 Martin Baulig <martin@gnome.org>
315 Improved breakpoint support, we can now dynamically insert and
316 remove breakpoints at runtime and when called from withing the
317 Mono Debugger, we're using a special breakpoint trampoline.
319 * debug.h (mono_method_has_breakpoint): New method to check
320 whether to insert a breakpoint for a method.
321 (mono_insert_breakpoint): New method to insert a breakpoint.
322 (mono_insert_breakpoint_full): New method to insert a breakpoint,
323 takes a MonoMethodDesc.
324 (mono_remove_breakpoint): New method to remove a breakpoint.
326 * debug.c (mono_debugger_insert_breakpoint): New function for the
327 debugger. Should only be called from the debugger.
328 (mono_debugger_remove_breakpoint): Likewise.
330 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
332 * trampoline.c (get_breakpoint_trampoline): New static function to
333 create a special breakpoint trampoline for the debugger.
334 (x86_magic_trampoline): If we're running inside the Mono Debugger
335 and a breakpoint was requested for the method, generate a special
336 breakpoint trampoline.
338 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
339 to insert a breakpoint.
340 (mono_debug_last_breakpoint_address): Removed.
341 (match_debug_method): Removed, use mono_method_has_breakpoint().
343 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
345 * jit.c: reorder mono_runtime_cleanup () call since it needs the
346 engine still fully working.
348 2002-09-24 Martin Baulig <martin@gnome.org>
350 * debug.c (mono_debug_open): When we're invoked from inside the
351 Mono Debugger, set mono_debugger_class_init_func (exported in
352 metadata/class.c) to mono_add_type().
353 (mono_add_type): Call mono_debug_symfile_add_type().
355 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
357 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
358 Run finalize on domain cleanup.
359 * mono.c: call setlocale ().
360 * trampoline.c: clearer error message for invalid trampoline.
362 2002-09-21 Martin Baulig <martin@gnome.org>
364 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
365 instead of writing a byte blob.
366 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
367 (mono_debug_add_method): Incrementally add the new method to the symbol
370 * exception.c (arch_handle_exception): If we have debugging support,
371 call mono_debugger_update_symbol_file_table () as well.
373 2002-09-20 Martin Baulig <martin@gnome.org>
375 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
376 the size of the variable.
378 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
380 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
381 iterations if we visit blocks in reverse order.
383 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
385 * jit.c (mono_analyze_stack): cleaup of the array code
387 * exception.c: added patch from Julio Merno to fix bug #30048
389 * jit.c (mono_analyze_stack): code cleanup, fix bug #29365
391 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
393 * x86.brg (LDELEMA): use x86_lea
395 2002-09-06 Martin Baulig <martin@gnome.org>
397 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
398 If you were getting random crashes when using the JIT with debugging
399 turned on, this fixes it.
401 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
403 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
405 2002-09-05 Martin Baulig <martin@gnome.org>
407 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
408 which is read by the debugger.
410 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>
412 * Makefile.am: link libmono directly into mono. Use a ld script
413 to reduce exported symbols.
415 2002-09-03 Martin Baulig <martin@gnome.org>
417 * debug.c (free_method_info): Make this actually work.
419 2002-09-03 Martin Baulig <martin@gnome.org>
421 * debug.h (MonoDebugFormat): Killed MONO_DEBUG_FORMAT_DWARF2_PLUS.
422 * debug-dwarf2-plus.c: Removed.
424 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
425 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
426 `mono_symfile' to `symfile'.
428 * debug.c (mono_debug_open): Replaced the assembly argument with a
429 file name argument; you can now call this before loading the assembly.
430 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
431 we now use MonoSymbolFileLineNumberEntry's and a separate address array
432 instead; splitted out all MonoSymbolFileLineNumberEntry code into
433 debug_generate_il_offsets() and debug_update_il_offsets().
434 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
435 created when reading the symbol file or from debug_load_method_lines().
436 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
438 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before
439 looking up an address.
441 * debug.c: Don't create the .il files for MONO_DEBUG_FORMAT_MONO.
443 * mono.c (main): Initialize debugging before loading the first assembly.
445 2002-08-28 Dick Porter <dick@ximian.com>
447 * mono.c: mono_set_rootdir() doesnt take any args now
449 * Makefile.am: Export HOST_CC for w32 builds
451 2002-08-28 Dietmar Maurer <dietmar@ximian.com>
453 * jit.c (mono_store_tree): only allocate vars if really necessary
455 2002-08-27 Martin Baulig <martin@gnome.org>
457 * debug.c: The mono symbol file is installed together with the assembly
458 it belongs to and it's used on a per-image basis.
460 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
462 * mono.c: don't use the cil-coff header outside of the loader.
464 2002-08-27 Martin Baulig <martin@gnome.org>
466 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
467 to use global variables for this since they're stored in a core file.
468 (mono_debugger_symbol_file_table_generation): New global variable.
469 (mono_debugger_symbol_file_table): New global variable.
470 (mono_debugger_update_symbol_file_table): New global function to update
471 the symbol file table.
473 2002-08-27 Martin Baulig <martin@gnome.org>
475 * trampoline.c (mono_generic_trampoline_code): New global variable.
476 (arch_create_jit_trampoline): Use the new global variable to store the
477 generic trampoline code instead of using a static one. This allows the
478 debugger to access this variable to check whether a method is a trampoline.
480 * debug.h (mono_generic_trampoline_code): Added external declaration.
482 2002-08-27 Martin Baulig <martin@gnome.org>
484 * debug.c (MonoDebugHandle): Moved the method hash into the
485 AssemblyDebugInfo struct since we need to use a separate hash for each
488 * debug.c: Added special undocumented command line argument to create a
489 symbol file for IL files on-the-fly. In this case, we also need to create
490 the IL files and parse them.
491 (mono_debugger_internal_get_symbol_files): Return something more reasonable.
493 2002-08-26 Martin Baulig <martin@gnome.org>
495 * debug.c (mono_debugger_internal_free_symbol_files): New function.
496 (mono_debugger_internal_symbol_files_changed): New global variable.
498 2002-08-24 Martin Baulig <martin@gnome.org>
500 * debug.c (mono_debugger_internal_get_symbol_files): New function.
502 2002-08-24 Martin Baulig <martin@gnome.org>
504 * debug.c (mono_debug_write_symbols): Added support for the new
507 * mono.c (main): The `--debug' argument now knows about a new
508 debugging format `mono' which will be used to display source lines
511 * debug.h (MonoDebugFormat): Added a new MONO_DEBUG_FORMAT_MONO
512 which will be used when displaying backtraces. It reads a new
515 2002-08-23 Martin Baulig <martin@gnome.org>
517 * jit.c (match_debug_method): Don't include runtime invoke methods
520 * mono.c (main): Accept `Main' as argument to --break to insert a
521 breakpoint on the application's main method.
523 2002-08-23 Martin Baulig <martin@gnome.org>
525 * debug-dwarf2.c (dwarf2_write_class_field): Don't include any static fields.
527 2002-08-21 Dietmar Maurer <dietmar@ximian.com>
529 * exception.c (arch_handle_exception): don't set stack_trace to
530 null (so that it contains the full trace even when we rethrow the
533 2002-08-19 Nick Drochak <ndrochak@gol.com>
535 * x86.brg (mono_llmult_ovf): Simplified the code greatly by refactoring
536 the algebraic form we are using. This also eliminated a silly overflow
537 of the intermediate result that was causing troubles.
539 2002-08-16 Nick Drochak <ndrochak@gol.com>
541 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers
544 2002-08-15 Nick Drochak <ndrochak@gol.com>
546 * x86.brg (mono_llmult_ovf): Fix so it throws an overflow when result
547 will not fit in 64 bits. Fixes bug #27375.
549 Wed Aug 14 17:31:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
551 * exception.c: updates for API changes in metadata/.
553 2002-08-13 Dietmar Maurer <dietmar@ximian.com>
555 * jit.c (mono_jit_init): use ((gpointer)-1) as end_of_stack
556 address for the main thread.
558 2002-08-12 Dietmar Maurer <dietmar@ximian.com>
560 * jit.c (mono_analyze_stack): added support for Thread::Abort ()
562 2002-08-08 Dietmar Maurer <dietmar@ximian.com>
564 * exception.c (arch_handle_exception): simply return and let the
565 libpthread/kernel restore the context. This should work on recent
566 versions of linuxthreads.
568 * jit.c (mono_runtime_install_handlers): switch back to use
569 sigaction from libpthreads. As long as this does not make problems
570 we should use this instead of syscall.
572 2002-08-07 Dietmar Maurer <dietmar@ximian.com>
574 * jit.c: removed the createdelegate icall
575 (mono_analyze_stack): special case Array::Address()
577 2002-08-06 Dietmar Maurer <dietmar@ximian.com>
579 * emit-x86.c (arch_emit_prologue): make the call to
580 mono_get_lmf_addr relocatable.
581 (arch_jit_compile_cfg): do not waste memory

1014 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
1015 file for all assemblies. Currently, the JIT doesn't put all methods
1016 from a single assembly into a continuous region of memory. We were
1017 previously creating valid DWARF 2 files for this, but unfortunately
1018 GDB's symbol tables get messed up when it reads more than one such file.

1116 * exception.c (arch_handle_exception): EIP now points to the call
1117 instruction, not to the instruction after the call. This fixes the
1118 bug reported by Linus Upson (tests/exception8.cs)

1488 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1489 numbers, we still need to generate the IL offsets here. Emit line numbers
1490 for `prologue_end_offset' (the first line of actual code) and
1491 `epilogue_begin_offset' (the line of the method's closing brace).
1492 Don't crash if cfg->bblocks [i].forest is NULL.
1493 (mono_debug_add_method): Don't crash if we don't have line numbers.
1494 Initialize the newly added fields.
1496 * debug-stabs.c: Record first and last line, emit filename info at the

1499 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1500 emit line number info for the first and last line.
1502 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

1536 * debug-stabs.c (write_method_stabs): Don't generate method lines if
1537 we don't have line number information. Use `minfo->method_info.this_offset'
1538 instead of hardcoding 8.

1566 2002-03-23 Martin Baulig <martin@gnome.org>
1568 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1569 to do it before the X86_CMP.

1602 removed everything which is already in MonoDebugMethodInfo.
1604 * debug.c (debug_generate_method_lines): Generate the MonoILOffsetInfo array.

1643 * debug.c (mono_debug_get_type): Recursively call this for all function members
1645 (mono_debug_add_method): Don't mangle function names, this must be done by the
1646 debugger backend if the debugging format needs mangled names.
1648 * debug-dwarf2.c: Improved support for classes, added member functions.
1650 2002-03-16 Martin Baulig <martin@gnome.org>
1652 * debug.c (mono_debug_get_type): Recursively call this for all members and
1653 parent classes of a class type.
1655 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1656 since GDB doesn't like Java very much.
1658 2002-03-16 Martin Baulig <martin@gnome.org>
1660 * debug-dwarf2.c: Added support for enums.
1662 2002-03-15 Martin Baulig <martin@gnome.org>

1683 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1685 (mono_debug_open_file): Added MonoDebugFormat argument.
1686 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1687 this function from GDB. It's now safe to call this function multiple times;
1688 it'll always write a complete debugging file.
1690 * debug.c: Splitted this file into a general part which remains in this file
1691 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1692 All public functions now call a corresponding format specific function.
1694 * debug.c: The following changes are private to debug.c:
1695 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1696 (record_line_number, debug_generate_method_lines): New private functions.
1697 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1698 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1699 mono_debug_open_assembly_dwarf2).
1700 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1701 now safe to call this function multiple times.
1702 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1703 returns an unique index for this type. It's used to ensure that we only write
1704 each class once to the debugging file.
1705 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1706 data structure, but don't directly write to the debugging file. This is done
1707 later from mono_debug_write_assembly().
1709 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1710 debugging output. Call mono_debug_close() on cleanup if necessary.
1712 2002-03-14 Martin Baulig <martin@gnome.org>
1714 * debug-private.h: New private header file.
1716 * debug-stabs.c: Added the stabs type generation stuff which was
1717 previously in debug.c.
1719 * debug-dwarf.c: Started to implement type support. We're currently

2335 also use LDIND_XX token to load values from a specific address
2336 instead of LDLOC/STLOC.
2338 * testjit.c: use the new adressing scheme everywhere:
2339 LDIND _XX (ADDR_X), and STIND_XX (ADDR_X, tree)
