1 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
3 * jit.c (mono_jit_compile_method): make sure runtime_init is called
4 (mono_analyze_stack): make sure runtime_init is called
6 2003-01-14 Martin Baulig <martin@ximian.com>
8 * debug.c (debugger_update_symbol_file_table): Moved all the
9 functionality into debugger_update_symbol_file_table_internal();
10 the latter one will be called from the background thread while
11 already owning the lock. This'll allow us to step into
12 debugger_update_symbol_file_table() in the debugger and debug it.
14 2003-01-14 Martin Baulig <martin@ximian.com>
16 * Makefile.am: Link against gthread.
18 * jit.c: After realizing that mono-mutex doesn't work either
19 because it doesn't support recursive mutexes on FreeBSD, rewrote
20 the whole thread stuff to use gthread. This seems to fix this
21 weird deadlock in the debugger as well.
23 2003-01-12 Alp Toker <alp@atoker.com>
25 * exception.c: Typo fix: insinde -> inside
27 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
29 * exception.c (ves_icall_get_frame_info): skip one more frame and also
30 MONO_WRAPPER_RUNTIME_INVOKE wrappers
31 (x86_unwind_native_frame): disable unnecessary assertion
33 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
35 * exception.c (ves_icall_get_frame_info): fix bug 36382
37 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
39 * jit.c: handle wrapper_data in NEWOBJ/CALL.
41 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
43 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
45 2003-01-06 Martin Baulig <martin@ximian.com>
47 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
49 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
50 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
52 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
54 * debug.c: Move must_send_finished var declaration out of #if win32
55 block (this fixes the build on win32)
57 2003-01-05 Martin Baulig <martin@ximian.com>
59 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
60 this is used when we're running inside the Mono Debugger
61 (mono_debugger_wait): Put the waiting code into a function of its own.
63 * mono.c (main): Call mono_debugger_jit_exec() instead of
64 mono_jit_exec() if we're running inside the Mono Debugger.
66 2003-01-05 Martin Baulig <martin@ximian.com>
68 * debug.h (MonoDebugFormat): Added
69 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
70 we're running inside the Mono Debugger prior to the args parsing.
72 2003-01-04 Martin Baulig <martin@ximian.com>
74 * debug.c (release_symbol_file_table): Only call this if we're
75 actually modifying the symbol tables.
76 (mono_debug_open): Always set the `mono_debugger_class_init_func'
77 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
79 2003-01-03 Martin Baulig <martin@ximian.com>
81 * debug.c: Disable the mono debugger stuff on Windows.
83 2003-01-03 Martin Baulig <martin@ximian.com>
85 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
86 function. This is called from the breakpoint trampoline to signal
87 the debugger and wait until it has reload the symbol tables.
89 * trampoline.c (get_breakpoint_trampoline): Call the new
90 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
91 trampoline just before the breakpoint.
93 2002-12-31 Martin Baulig <martin@ximian.com>
95 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
96 field to point to the MonoGlobalSymbolTable.
98 2002-12-30 Martin Baulig <martin@ximian.com>
100 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
101 This variable now specifies that the symbol tables have been
102 modified after the last notification has been send. The debugger
103 uses this flag to check whether it needs to reload the symbol
105 (debugger_compile_method): Just send a notification to the
106 debugger, but don't set the modified flag. It may or may not be
107 set when the debugger gets the notification - depending on whether
108 the JIT compilation added a new method to the symbol tables.
110 2002-12-30 Martin Baulig <martin@ximian.com>
112 * debug.c (debugger_compile_method): This is a wrapper around
113 mono_compile_method() which always sends a notification to the
116 2002-12-30 Martin Baulig <martin@ximian.com>
118 * debug.c: Reload the symbol file table before sending the
119 notification event to the debugger.
120 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
122 2002-12-31 Martin Baulig <martin@ximian.com>
124 * debug.c: Propertly lock everything and avoid race conditions.
125 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
127 2002-12-31 Duncan Mak <duncan@ximian.com>
129 * debug.c (initialize_debugger_support): Fix build error by
130 declaring ret at the top of the function.
132 2002-12-30 Martin Baulig <martin@ximian.com>
134 * debug.c: When running under the mono debugger, create a special
135 debugger thread; always protect the symbol tables with a mutex.
137 2002-12-28 Martin Baulig <martin@ximian.com>
139 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
140 incremented each time one of the symbol tables is modified.
142 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
144 * jit.c: fix LDELEMA implementation here as well.
146 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
148 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
150 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
152 * jit.c: query the thread abort signal from the runtime.
154 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
156 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
158 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
160 * jit.c (mono_analyze_stack): call the utility function
161 mono_field_from_token to avoid code duplication.
163 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
165 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
167 * x86.brg (stmt): POP floating point stack correctly
169 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
171 * emit-x86.c (arch_emit_prologue): don't save caller saved
174 * exception.c (x86_unwind_native_frame): support exceptions inside
175 native code using gcc generated exception tables (-fexception).
177 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
179 * exception.c: include some code from Zoltan Varga, but modified
182 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
184 * exception.c: massive code cleanups. The code is still
185 architecture dependent, but it should be now possible to reuse the
186 complex parts for other architecture.
188 2002-11-15 Dick Porter <dick@ximian.com>
190 * jit.c: Pass the attach callback to mono_runtime_init().
192 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
194 * jit.c: display the domain name in trace output.
196 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
198 * x86.brg (reg): fix bug #2721
200 * jit.c (mono_runtime_install_handlers): impl.
202 2002-10-17 Martin Baulig <martin@gnome.org>
204 * debug.c (mono_debug_add_method): Make this actually work if we don't
205 have any lifetime information.
207 2002-10-15 Martin Baulig <martin@gnome.org>
209 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
211 * debug.c (generate_line_number): Small fix to make this actually
212 work for more complex things.
214 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
216 * x86.brg (freg): use fprem instead of fprem1
218 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
220 * jit.c (ves_array_element_address): added check for out of range index
221 (mono_analyze_stack): added fix for bug #31654
223 2002-10-01 Martin Baulig <martin@gnome.org>
225 * debug.c: Don't create an .il file for the dynamic symbol file.
227 2002-10-01 Martin Baulig <martin@gnome.org>
229 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
231 2002-09-27 Martin Baulig <martin@gnome.org>
233 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
235 2002-09-27 Dick Porter <dick@ximian.com>
237 * mono.c: Tell glib what the program name is, by passing it the
238 name of the managed file we're executing
240 2002-09-26 Martin Baulig <martin@gnome.org>
242 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
243 trampoline into the vtable, also use it for non-virtual methods,
244 remove the breakpoint when done.
246 2002-09-26 Martin Baulig <martin@gnome.org>
248 * debug.c (debug_load_method_lines): Block SIGCHLD while running
251 2002-09-26 Martin Baulig <martin@gnome.org>
253 * debug.c: Reworked the whole debugging stuff. We have now one
254 single `mono_debug_handle' which keeps a hashtable of
255 `AssemblyDebugInfo's (which may have different debugging formats).
256 The AssemblyDebugInfo is now created when the assembly is loaded,
257 but never when adding a class/type.
259 * mono.c: Initialize debugging stuff after corlib and the assembly
262 2002-09-25 Martin Baulig <martin@gnome.org>
264 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
265 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
267 (DebugMethodInfo): Removed `line_numbers'.
269 * debug.c: Reworked the line number generation; we're now using
270 the MonoDebugLineNumberEntry try for all debugging formats. This
271 type also includes the line number and IL offset, this allows the
272 JIT to produce better line number info: we only emit line number
273 information for source lines which actually have code.
275 2002-09-25 Martin Baulig <martin@gnome.org>
277 * debug.h: Removed external declaration of all functions which
278 should only be called from the Mono Debugger and also made them
279 static. Since the debugger gets their address from the
280 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
283 2002-09-25 Martin Baulig <martin@gnome.org>
285 Improved breakpoint support, we can now dynamically insert and
286 remove breakpoints at runtime and when called from withing the
287 Mono Debugger, we're using a special breakpoint trampoline.
289 * debug.h (mono_method_has_breakpoint): New method to check
290 whether to insert a breakpoint for a method.
291 (mono_insert_breakpoint): New method to insert a breakpoint.
292 (mono_insert_breakpoint_full): New method to insert a breakpoint,
293 takes a MonoMethodDesc.
294 (mono_remove_breakpoint): New method to remove a breakpoint.
296 * debug.c (mono_debugger_insert_breakpoint): New function for the
297 debugger. Should only be called from the debugger.
298 (mono_debugger_remove_breakpoint): Likewise.
300 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
302 * trampoline.c (get_breakpoint_trampoline): New static function to
303 create a special breakpoint trampoline for the debugger.
304 (x86_magic_trampoline): If we're running inside the Mono Debugger
305 and a breakpoint was requested for the method, generate a special
306 breakpoint trampoline.
308 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
309 to insert a breakpoint.
310 (mono_debug_last_breakpoint_address): Removed.
311 (match_debug_method): Removed, use mono_method_has_breakpoint().
313 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
315 * jit.c: reorder mono_runtime_cleanup () call since it needs the
316 engine still fully working.
318 2002-09-24 Martin Baulig <martin@gnome.org>
320 * debug.c (mono_debug_open): When we're invoked from inside the
321 Mono Debugger, set mono_debugger_class_init_func (exported in
322 metadata/class.c) to mono_add_type().
323 (mono_add_type): Call mono_debug_symfile_add_type().
325 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
327 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
328 Run finalize on domain cleanup.
329 * mono.c: call setlocale ().
330 * trampoline.c: clearer error message for invalid trampoline.
332 2002-09-21 Martin Baulig <martin@gnome.org>
334 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
335 instead of writing a byte blob.
336 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
337 (mono_debug_add_method): Incrementally add the new method to the symbol
340 * exception.c (arch_handle_exception): If we have debugging support,
341 call mono_debugger_update_symbol_file_table () as well.
343 2002-09-20 Martin Baulig <martin@gnome.org>
345 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
346 the size of the variable.
348 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
350 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
351 iterations if we visit blocks in reverse order.
353 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
355 * jit.c (mono_analyze_stack): cleaup of the array code
357 * exception.c: added patch from Julio Merno to fix bug #30048
359 * jit.c (mono_analyze_stack): code cleanup, fix bug #29365
361 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
363 * x86.brg (LDELEMA): use x86_lea
365 2002-09-06 Martin Baulig <martin@gnome.org>
367 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
368 If you were getting random crashes when using the JIT with debugging
369 turned on, this fixes it.
371 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
373 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
375 2002-09-05 Martin Baulig <martin@gnome.org>
377 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
378 which is read by the debugger.
380 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>
382 * Makefile.am: link libmono directly into mono. Use a ld script
383 to reduce exported symbols.
385 2002-09-03 Martin Baulig <martin@gnome.org>
387 * debug.c (free_method_info): Make this actually work.
389 2002-09-03 Martin Baulig <martin@gnome.org>
391 * debug.h (MonoDebugFormat): Killed MONO_DEBUG_FORMAT_DWARF2_PLUS.
392 * debug-dwarf2-plus.c: Removed.
394 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
395 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
396 `mono_symfile' to `symfile'.
398 * debug.c (mono_debug_open): Replaced the assembly argument with a
399 file name argument; you can now call this before loading the assembly.
400 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
401 we now use MonoSymbolFileLineNumberEntry's and a separate address array
402 instead; splitted out all MonoSymbolFileLineNumberEntry code into
403 debug_generate_il_offsets() and debug_update_il_offsets().
404 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
405 created when reading the symbol file or from debug_load_method_lines().
406 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
408 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before
409 looking up an address.
411 * debug.c: Don't create the .il files for MONO_DEBUG_FORMAT_MONO.
413 * mono.c (main): Initialize debugging before loading the first assembly.
415 2002-08-28 Dick Porter <dick@ximian.com>
417 * mono.c: mono_set_rootdir() doesnt take any args now

425 2002-08-27 Martin Baulig <martin@gnome.org>
427 * debug.c: The mono symbol file is installed together with the assembly
428 it belongs to and it's used on a per-image basis.
430 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
432 * mono.c: don't use the cil-coff header outside of the loader.
434 2002-08-27 Martin Baulig <martin@gnome.org>
436 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
437 to use global variables for this since they're stored in a core file.
438 (mono_debugger_symbol_file_table_generation): New global variable.
439 (mono_debugger_symbol_file_table): New global variable.
440 (mono_debugger_update_symbol_file_table): New global function to update
441 the symbol file table.
443 2002-08-27 Martin Baulig <martin@gnome.org>
445 * trampoline.c (mono_generic_trampoline_code): New global variable.
446 (arch_create_jit_trampoline): Use the new global variable to store the
447 generic trampoline code instead of using a static one. This allows the
448 debugger to access this variable to check whether a method is a trampoline.
450 * debug.h (mono_generic_trampoline_code): Added external declaration.
452 2002-08-27 Martin Baulig <martin@gnome.org>
454 * debug.c (MonoDebugHandle): Moved the method hash into the
455 AssemblyDebugInfo struct since we need to use a separate hash for each
458 * debug.c: Added special undocumented command line argument to create a
459 symbol file for IL files on-the-fly. In this case, we also need to create
460 the IL files and parse them.
461 (mono_debugger_internal_get_symbol_files): Return something more reasonable.
463 2002-08-26 Martin Baulig <martin@gnome.org>
465 * debug.c (mono_debugger_internal_free_symbol_files): New function.
466 (mono_debugger_internal_symbol_files_changed): New global variable.
468 2002-08-24 Martin Baulig <martin@gnome.org>
470 * debug.c (mono_debugger_internal_get_symbol_files): New function.
472 2002-08-24 Martin Baulig <martin@gnome.org>
474 * debug.c (mono_debug_write_symbols): Added support for the new
477 * mono.c (main): The `--debug' argument now knows about a new
478 debugging format `mono' which will be used to display source lines
481 * debug.h (MonoDebugFormat): Added a new MONO_DEBUG_FORMAT_MONO
482 which will be used when displaying backtraces. It reads a new
485 2002-08-23 Martin Baulig <martin@gnome.org>
487 * jit.c (match_debug_method): Don't include runtime invoke methods
490 * mono.c (main): Accept `Main' as argument to --break to insert a
491 breakpoint on the application's main method.
493 2002-08-23 Martin Baulig <martin@gnome.org>

497 2002-08-21 Dietmar Maurer <dietmar@ximian.com>
499 * exception.c (arch_handle_exception): don't set stack_trace to
500 null (so that it contains the full trace even when we rethrow the
503 2002-08-19 Nick Drochak <ndrochak@gol.com>
505 * x86.brg (mono_llmult_ovf): Simplified the code greatly by refactoring
506 the algebraic form we are using. This also eliminated a silly overflow
507 of the intermediate result that was causing troubles.
509 2002-08-16 Nick Drochak <ndrochak@gol.com>
511 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers
514 2002-08-15 Nick Drochak <ndrochak@gol.com>
516 * x86.brg (mono_llmult_ovf): Fix so it throws an overflow when result
517 will not fit in 64 bits. Fixes bug #27375.
519 Wed Aug 14 17:31:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
521 * exception.c: updates for API changes in metadata/.
523 2002-08-13 Dietmar Maurer <dietmar@ximian.com>

526 address for the main thread.
528 2002-08-12 Dietmar Maurer <dietmar@ximian.com>
530 * jit.c (mono_analyze_stack): added support for Thread::Abort ()
532 2002-08-08 Dietmar Maurer <dietmar@ximian.com>
534 * exception.c (arch_handle_exception): simply return and let the
535 libpthread/kernel restore the context. This should work on recent
536 versions of linuxthreads.
538 * jit.c (mono_runtime_install_handlers): switch back to use
539 sigaction from libpthreads. As long as this does not make problems
540 we should use this instead of syscall.
542 2002-08-07 Dietmar Maurer <dietmar@ximian.com>
544 * jit.c: removed the createdelegate icall
545 (mono_analyze_stack): special case Array::Address()
547 2002-08-06 Dietmar Maurer <dietmar@ximian.com>
549 * emit-x86.c (arch_emit_prologue): make the call to
550 mono_get_lmf_addr relocatable.
551 (arch_jit_compile_cfg): do not waste memory
552 (arch_jit_compile_cfg): use a mempool to store native code. This
553 improves locality of code.
555 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
557 * jit.c (mono_analyze_stack): impl. CEE_MONO_RETOBJ
559 2002-07-30 Sergey Chaban <serge@wildwestsoftware.com>
561 * x86.brg (LOCALLOC): under Windows, if allocation size is bigger
562 than one page, it's necessary to allocate memory incrementally,
563 in page-size steps, performing stack-touch every time.
564 Also added LOCALLOC(CONST_I4) implementation.
566 2002-07-27 Dietmar Maurer <dietmar@ximian.com>
568 * jit.c (mono_get_runtime_method): code cleanup
570 * x86.brg: we do not need to save EAX/ECX/EDX in stmt:
572 2002-07-24 Dietmar Maurer <dietmar@ximian.com>
574 * jit.c (mono_analyze_stack): added CEE_TAIL (but it is ignored)
576 Wed Jul 24 13:02:50 CEST 2002 Paolo Molaro <lupus@ximian.com>
578 * jit.c, jit.h, exception.c: implemented stack walking function.
580 2002-07-24 Dietmar Maurer <dietmar@ximian.com>

984 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
985 file for all assemblies. Currently, the JIT doesn't put all methods
986 from a single assembly into a continuous region of memory. We were

1086 * exception.c (arch_handle_exception): EIP now points to the call
1087 instruction, not to the instruction after the call. This fixes the

1458 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1459 numbers, we still need to generate the IL offsets here. Emit line numbers
1460 for `prologue_end_offset' (the first line of actual code) and
1461 `epilogue_begin_offset' (the line of the method's closing brace).
1462 Don't crash if cfg->bblocks [i].forest is NULL.
1463 (mono_debug_add_method): Don't crash if we don't have line numbers.
1464 Initialize the newly added fields.
1466 * debug-stabs.c: Record first and last line, emit filename info at the

1469 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1470 emit line number info for the first and last line.
1472 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

1536 2002-03-23 Martin Baulig <martin@gnome.org>
1538 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1539 to do it before the X86_CMP.
1540 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1541 (reg: CLT (lreg, lreg)): Likewise.
1542 (reg: CLT_UN (lreg, lreg)): Likewise.

1572 removed everything which is already in MonoDebugMethodInfo.
1574 * debug.c (debug_generate_method_lines): Generate the MonoILOffsetInfo array.

1613 * debug.c (mono_debug_get_type): Recursively call this for all function members
1615 (mono_debug_add_method): Don't mangle function names, this must be done by the
1616 debugger backend if the debugging format needs mangled names.
1618 * debug-dwarf2.c: Improved support for classes, added member functions.
1620 2002-03-16 Martin Baulig <martin@gnome.org>
1622 * debug.c (mono_debug_get_type): Recursively call this for all members and
1623 parent classes of a class type.
1625 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1626 since GDB doesn't like Java very much.
1628 2002-03-16 Martin Baulig <martin@gnome.org>
1630 * debug-dwarf2.c: Added support for enums.
1632 2002-03-15 Martin Baulig <martin@gnome.org>

1651 2002-03-14 Martin Baulig <martin@gnome.org>
1653 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1655 (mono_debug_open_file): Added MonoDebugFormat argument.
1656 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1657 this function from GDB. It's now safe to call this function multiple times;
1658 it'll always write a complete debugging file.
1660 * debug.c: Splitted this file into a general part which remains in this file
1661 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1662 All public functions now call a corresponding format specific function.
1664 * debug.c: The following changes are private to debug.c:
1665 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1666 (record_line_number, debug_generate_method_lines): New private functions.
1667 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1668 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1669 mono_debug_open_assembly_dwarf2).
1670 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1671 now safe to call this function multiple times.
1672 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1673 returns an unique index for this type. It's used to ensure that we only write
1674 each class once to the debugging file.
1675 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1676 data structure, but don't directly write to the debugging file. This is done
1677 later from mono_debug_write_assembly().
1679 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1680 debugging output. Call mono_debug_close() on cleanup if necessary.
1682 2002-03-14 Martin Baulig <martin@gnome.org>
1684 * debug-private.h: New private header file.
1686 * debug-stabs.c: Added the stabs type generation stuff which was
1687 previously in debug.c.
1689 * debug-dwarf.c: Started to implement type support. We're currently
1690 only writing this most basic types to the dwarf file, but this will
1693 2002-03-13 Martin Baulig <martin@gnome.org>
1695 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1696 debugging code. They're now in CVS, but not yet used anywhere.
1698 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1700 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1701 macros, included new delegate code from Daniel Stodden.
1704 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1706 * jit.c: verify that corlib and runtime are in sync.
1708 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1710 * emit-x86.c, jit.c: use the debug-helpers facilities to
1711 describe and match a method when debugging.
1713 2002-03-10 Martin Baulig <martin@gnome.org>
1715 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1716 output, put a nop instruction at the start of all functions so that
1717 the adresses won't change when using --debug.
1719 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1720 the bytecode area, stabs needs a line number in the .il file. Use the
1721 new info->moffsets to get the line number.
1722 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1723 `moffsets' is an array of `total_lines' fields (total number of lines
1724 in the .il file); for each line in the .il field, this array contains

2294 (map_stind_type): add enumeration types.
2296 * emit-x86.c (arch_compile_method): more documentation.
2298 * testjit.c: moved the architecture specific things to emit-x86.c
2299 and x86.brg. Added more documentation. code cleanup.
2301 2001-09-25 Dietmar Maurer <dietmar@ximian.com>
2303 * x86.brg: we now have different types of addresses: ADDR_L for local
2304 values, ADDR_A for arguments and ADDR_G for global addresses. We
2305 also use LDIND_XX token to load values from a specific address
2306 instead of LDLOC/STLOC.
2308 * testjit.c: use the new adressing scheme everywhere:
2309 LDIND _XX (ADDR_X), and STIND_XX (ADDR_X, tree)

2370 * testjit.c (get_address): use a binary search to get the address
2371 (main): added an option to debug the jit (-d)
2373 Tue Sep 18 13:19:16 CEST 2001 Paolo Molaro <lupus@ximian.com>
2375 * testjit.c: better/faster align code. Handle ldloc.s and stloc.s.
2377 2001-09-17 Miguel de Icaza <miguel@ximian.com>
2379 * testjit.c (mono_compile_method): Provide better error reporting.
2381 2001-09-17 Dietmar Maurer <dietmar@ximian.com>
2383 * testjit.c (tree_get_address): impl. to fix address bug

2409 2001-09-13 Dietmar Maurer <dietmar@ximian.com>
2411 * x86.brg: use the right offsets to access local variables
2414 * emit-x86.c: only save/restore callee saved registers if they are
2417 * testjit.c (tree_allocate_regs): use the new MonoRegSet to
2419 (mono_compile_method): changed the tree for mothod calls
2426 2001-09-10 Miguel de Icaza <miguel@ximian.com>
2428 * x86.brg: Use Unix assembly syntax.
2430 * emit-x86.c: support code, should be moved
