1 2003-01-18 Martin Baulig <martin@ximian.com>
3 * debug.c (mono_debugger_jit_exec): Send the background thread a
4 SIGKILL before returning.
6 2003-01-17 Dietmar Maurer <dietmar@ximian.com>
8 * x86.brg: removed duplicated CONV_OVF_I4
10 2003-01-17 Martin Baulig <martin@ximian.com>
12 * debug.c: Don't use mono_once here. Reworked the API a bit to
13 use `mono_debug_' and `debug_' for the general debugging API and
14 `mono_debugger_' and `debugger_' for the Mono Debugger stuff.
16 2003-01-16 Martin Baulig <martin@ximian.com>
18 * debug.c (debugger_thread_func): We don't need to `raise
19 (SIGSTOP)' anymore; the thread manager already takes care of this.
21 2003-01-16 Dietmar Maurer <dietmar@ximian.com>
23 * exception.c (arch_handle_exception): exclude runtime invoke
24 wrapper from the stack trace
26 * jit.c (mono_cfg_new): allocate extra space to store esp (used by exceptions)
27 (mono_thread_start_cb): save an additional LMF at thread start
29 2003-01-16 Martin Baulig <martin@ximian.com>
31 * jit.c (mono_runtime_install_handlers): Use SYS_sigaction() for
32 the mono_thread_get_abort_signal () - this is SIGUSR1 on FreeBSD
33 and the LinuxThreads port doesn't allow you to override the handler.
34 [FIXME: This avoids an assertion failure on startup, but there's
35 still an issue with thread termination.]
37 2003-01-16 Martin Baulig <martin@ximian.com>
39 * debug.c (debugger_thread_func): We don't need to `raise
40 (SIGSTOP)' anymore; the thread manager already takes care of this.
42 2003-01-16 Martin Baulig <martin@ximian.com>
44 * debug.c: Use the mono/io-layer functions here instead of gthread.
46 2003-01-14 Dietmar Maurer <dietmar@ximian.com>
48 * jit.c (mono_jit_compile_method): make sure runtime_init is called
49 (mono_analyze_stack): make sure runtime_init is called
51 2003-01-14 Martin Baulig <martin@ximian.com>
53 * debug.c (debugger_update_symbol_file_table): Moved all the
54 functionality into debugger_update_symbol_file_table_internal();
55 the latter one will be called from the background thread while
56 already owning the lock. This'll allow us to step into
57 debugger_update_symbol_file_table() in the debugger and debug it.
59 2003-01-14 Martin Baulig <martin@ximian.com>
61 * Makefile.am: Link against gthread.
63 * jit.c: After realizing that mono-mutex doesn't work either
64 because it doesn't support recursive mutexes on FreeBSD, rewrote
65 the whole thread stuff to use gthread. This seems to fix this
66 weird deadlock in the debugger as well.
68 2003-01-12 Alp Toker <alp@atoker.com>
70 * exception.c: Typo fix: insinde -> inside
72 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
74 * exception.c (ves_icall_get_frame_info): skip one more frame and also
75 MONO_WRAPPER_RUNTIME_INVOKE wrappers
76 (x86_unwind_native_frame): disable unnecessary assertion
78 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
80 * exception.c (ves_icall_get_frame_info): fix bug 36382
82 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
84 * jit.c: handle wrapper_data in NEWOBJ/CALL.
86 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
88 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
90 2003-01-06 Martin Baulig <martin@ximian.com>
92 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
94 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
95 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
97 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
99 * debug.c: Move must_send_finished var declaration out of #if win32
100 block (this fixes the build on win32)
102 2003-01-05 Martin Baulig <martin@ximian.com>
104 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
105 this is used when we're running inside the Mono Debugger
106 (mono_debugger_wait): Put the waiting code into a function of its own.
108 * mono.c (main): Call mono_debugger_jit_exec() instead of
109 mono_jit_exec() if we're running inside the Mono Debugger.
111 2003-01-05 Martin Baulig <martin@ximian.com>
113 * debug.h (MonoDebugFormat): Added
114 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
115 we're running inside the Mono Debugger prior to the args parsing.
117 2003-01-04 Martin Baulig <martin@ximian.com>
119 * debug.c (release_symbol_file_table): Only call this if we're
120 actually modifying the symbol tables.
121 (mono_debug_open): Always set the `mono_debugger_class_init_func'
122 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
124 2003-01-03 Martin Baulig <martin@ximian.com>
126 * debug.c: Disable the mono debugger stuff on Windows.
128 2003-01-03 Martin Baulig <martin@ximian.com>
130 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
131 function. This is called from the breakpoint trampoline to signal
132 the debugger and wait until it has reload the symbol tables.
134 * trampoline.c (get_breakpoint_trampoline): Call the new
135 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
136 trampoline just before the breakpoint.
138 2002-12-31 Martin Baulig <martin@ximian.com>
140 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
141 field to point to the MonoGlobalSymbolTable.
143 2002-12-30 Martin Baulig <martin@ximian.com>
145 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
146 This variable now specifies that the symbol tables have been
147 modified after the last notification has been send. The debugger
148 uses this flag to check whether it needs to reload the symbol
150 (debugger_compile_method): Just send a notification to the
151 debugger, but don't set the modified flag. It may or may not be
152 set when the debugger gets the notification - depending on whether
153 the JIT compilation added a new method to the symbol tables.
155 2002-12-30 Martin Baulig <martin@ximian.com>
157 * debug.c (debugger_compile_method): This is a wrapper around
158 mono_compile_method() which always sends a notification to the
161 2002-12-30 Martin Baulig <martin@ximian.com>
163 * debug.c: Reload the symbol file table before sending the
164 notification event to the debugger.
165 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
167 2002-12-31 Martin Baulig <martin@ximian.com>
169 * debug.c: Propertly lock everything and avoid race conditions.
170 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
172 2002-12-31 Duncan Mak <duncan@ximian.com>
174 * debug.c (initialize_debugger_support): Fix build error by
175 declaring ret at the top of the function.
177 2002-12-30 Martin Baulig <martin@ximian.com>
179 * debug.c: When running under the mono debugger, create a special
180 debugger thread; always protect the symbol tables with a mutex.
182 2002-12-28 Martin Baulig <martin@ximian.com>
184 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
185 incremented each time one of the symbol tables is modified.
187 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
189 * jit.c: fix LDELEMA implementation here as well.
191 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
193 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.
195 Wed Dec 18 11:36:04 CET 2002 Paolo Molaro <lupus@ximian.com>
197 * jit.c: query the thread abort signal from the runtime.
199 2002-12-12 Juli Mallett <jmallett@FreeBSD.org>
201 * jit.c: If SIGRTMIN is not defined, fall back to SIGUSR1.
203 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
205 * jit.c (mono_analyze_stack): call the utility function
206 mono_field_from_token to avoid code duplication.
208 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
210 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
212 * x86.brg (stmt): POP floating point stack correctly
214 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
216 * emit-x86.c (arch_emit_prologue): don't save caller saved
219 * exception.c (x86_unwind_native_frame): support exceptions inside
220 native code using gcc generated exception tables (-fexception).
222 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
224 * exception.c: include some code from Zoltan Varga, but modified
227 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
229 * exception.c: massive code cleanups. The code is still
230 architecture dependent, but it should be now possible to reuse the
231 complex parts for other architecture.
233 2002-11-15 Dick Porter <dick@ximian.com>
235 * jit.c: Pass the attach callback to mono_runtime_init().
237 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
239 * jit.c: display the domain name in trace output.
241 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
243 * x86.brg (reg): fix bug #2721
245 * jit.c (mono_runtime_install_handlers): impl.
247 2002-10-17 Martin Baulig <martin@gnome.org>
249 * debug.c (mono_debug_add_method): Make this actually work if we don't
250 have any lifetime information.
252 2002-10-15 Martin Baulig <martin@gnome.org>
254 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
256 * debug.c (generate_line_number): Small fix to make this actually
257 work for more complex things.
259 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
261 * x86.brg (freg): use fprem instead of fprem1
263 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
265 * jit.c (ves_array_element_address): added check for out of range index
266 (mono_analyze_stack): added fix for bug #31654
268 2002-10-01 Martin Baulig <martin@gnome.org>
270 * debug.c: Don't create an .il file for the dynamic symbol file.
272 2002-10-01 Martin Baulig <martin@gnome.org>
274 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
276 2002-09-27 Martin Baulig <martin@gnome.org>
278 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
280 2002-09-27 Dick Porter <dick@ximian.com>
282 * mono.c: Tell glib what the program name is, by passing it the
283 name of the managed file we're executing
285 2002-09-26 Martin Baulig <martin@gnome.org>
287 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
288 trampoline into the vtable, also use it for non-virtual methods,
289 remove the breakpoint when done.
291 2002-09-26 Martin Baulig <martin@gnome.org>
293 * debug.c (debug_load_method_lines): Block SIGCHLD while running
296 2002-09-26 Martin Baulig <martin@gnome.org>
298 * debug.c: Reworked the whole debugging stuff. We have now one
299 single `mono_debug_handle' which keeps a hashtable of
300 `AssemblyDebugInfo's (which may have different debugging formats).
301 The AssemblyDebugInfo is now created when the assembly is loaded,
302 but never when adding a class/type.
304 * mono.c: Initialize debugging stuff after corlib and the assembly
307 2002-09-25 Martin Baulig <martin@gnome.org>
309 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
310 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
312 (DebugMethodInfo): Removed `line_numbers'.
314 * debug.c: Reworked the line number generation; we're now using
315 the MonoDebugLineNumberEntry try for all debugging formats. This
316 type also includes the line number and IL offset, this allows the
317 JIT to produce better line number info: we only emit line number
318 information for source lines which actually have code.
320 2002-09-25 Martin Baulig <martin@gnome.org>
322 * debug.h: Removed external declaration of all functions which
323 should only be called from the Mono Debugger and also made them
324 static. Since the debugger gets their address from the
325 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
328 2002-09-25 Martin Baulig <martin@gnome.org>
330 Improved breakpoint support, we can now dynamically insert and
331 remove breakpoints at runtime and when called from withing the
332 Mono Debugger, we're using a special breakpoint trampoline.
334 * debug.h (mono_method_has_breakpoint): New method to check
335 whether to insert a breakpoint for a method.
336 (mono_insert_breakpoint): New method to insert a breakpoint.
337 (mono_insert_breakpoint_full): New method to insert a breakpoint,
338 takes a MonoMethodDesc.
339 (mono_remove_breakpoint): New method to remove a breakpoint.
341 * debug.c (mono_debugger_insert_breakpoint): New function for the
342 debugger. Should only be called from the debugger.
343 (mono_debugger_remove_breakpoint): Likewise.
345 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
347 * trampoline.c (get_breakpoint_trampoline): New static function to
348 create a special breakpoint trampoline for the debugger.
349 (x86_magic_trampoline): If we're running inside the Mono Debugger
350 and a breakpoint was requested for the method, generate a special
351 breakpoint trampoline.
353 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
354 to insert a breakpoint.
355 (mono_debug_last_breakpoint_address): Removed.
356 (match_debug_method): Removed, use mono_method_has_breakpoint().
358 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
360 * jit.c: reorder mono_runtime_cleanup () call since it needs the
361 engine still fully working.
363 2002-09-24 Martin Baulig <martin@gnome.org>
365 * debug.c (mono_debug_open): When we're invoked from inside the
366 Mono Debugger, set mono_debugger_class_init_func (exported in
367 metadata/class.c) to mono_add_type().
368 (mono_add_type): Call mono_debug_symfile_add_type().
370 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
372 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
373 Run finalize on domain cleanup.
374 * mono.c: call setlocale ().
375 * trampoline.c: clearer error message for invalid trampoline.
377 2002-09-21 Martin Baulig <martin@gnome.org>
379 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
380 instead of writing a byte blob.
381 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
382 (mono_debug_add_method): Incrementally add the new method to the symbol
385 * exception.c (arch_handle_exception): If we have debugging support,
386 call mono_debugger_update_symbol_file_table () as well.
388 2002-09-20 Martin Baulig <martin@gnome.org>
390 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
391 the size of the variable.
393 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
395 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
396 iterations if we visit blocks in reverse order.
398 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
400 * jit.c (mono_analyze_stack): cleaup of the array code
402 * exception.c: added patch from Julio Merno to fix bug #30048
404 * jit.c (mono_analyze_stack): code cleanup, fix bug #29365
406 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
408 * x86.brg (LDELEMA): use x86_lea
410 2002-09-06 Martin Baulig <martin@gnome.org>
412 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
413 If you were getting random crashes when using the JIT with debugging
414 turned on, this fixes it.
416 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
418 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
420 2002-09-05 Martin Baulig <martin@gnome.org>
422 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
423 which is read by the debugger.
425 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>
427 * Makefile.am: link libmono directly into mono. Use a ld script
428 to reduce exported symbols.
430 2002-09-03 Martin Baulig <martin@gnome.org>
432 * debug.c (free_method_info): Make this actually work.
434 2002-09-03 Martin Baulig <martin@gnome.org>
436 * debug.h (MonoDebugFormat): Killed MONO_DEBUG_FORMAT_DWARF2_PLUS.
437 * debug-dwarf2-plus.c: Removed.
439 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
440 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
441 `mono_symfile' to `symfile'.
443 * debug.c (mono_debug_open): Replaced the assembly argument with a
444 file name argument; you can now call this before loading the assembly.
445 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
446 we now use MonoSymbolFileLineNumberEntry's and a separate address array
447 instead; splitted out all MonoSymbolFileLineNumberEntry code into
448 debug_generate_il_offsets() and debug_update_il_offsets().
449 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
450 created when reading the symbol file or from debug_load_method_lines().
451 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
453 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before
454 looking up an address.
456 * debug.c: Don't create the .il files for MONO_DEBUG_FORMAT_MONO.
458 * mono.c (main): Initialize debugging before loading the first assembly.
460 2002-08-28 Dick Porter <dick@ximian.com>
462 * mono.c: mono_set_rootdir() doesnt take any args now
464 * Makefile.am: Export HOST_CC for w32 builds
466 2002-08-28 Dietmar Maurer <dietmar@ximian.com>
468 * jit.c (mono_store_tree): only allocate vars if really necessary
470 2002-08-27 Martin Baulig <martin@gnome.org>
472 * debug.c: The mono symbol file is installed together with the assembly
473 it belongs to and it's used on a per-image basis.
475 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
477 * mono.c: don't use the cil-coff header outside of the loader.
479 2002-08-27 Martin Baulig <martin@gnome.org>
481 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
482 to use global variables for this since they're stored in a core file.
483 (mono_debugger_symbol_file_table_generation): New global variable.
484 (mono_debugger_symbol_file_table): New global variable.
485 (mono_debugger_update_symbol_file_table): New global function to update
486 the symbol file table.
488 2002-08-27 Martin Baulig <martin@gnome.org>
490 * trampoline.c (mono_generic_trampoline_code): New global variable.
491 (arch_create_jit_trampoline): Use the new global variable to store the
492 generic trampoline code instead of using a static one. This allows the
493 debugger to access this variable to check whether a method is a trampoline.
495 * debug.h (mono_generic_trampoline_code): Added external declaration.
497 2002-08-27 Martin Baulig <martin@gnome.org>
499 * debug.c (MonoDebugHandle): Moved the method hash into the
500 AssemblyDebugInfo struct since we need to use a separate hash for each
503 * debug.c: Added special undocumented command line argument to create a
504 symbol file for IL files on-the-fly. In this case, we also need to create
505 the IL files and parse them.
506 (mono_debugger_internal_get_symbol_files): Return something more reasonable.
508 2002-08-26 Martin Baulig <martin@gnome.org>
510 * debug.c (mono_debugger_internal_free_symbol_files): New function.
511 (mono_debugger_internal_symbol_files_changed): New global variable.
513 2002-08-24 Martin Baulig <martin@gnome.org>
515 * debug.c (mono_debugger_internal_get_symbol_files): New function.
517 2002-08-24 Martin Baulig <martin@gnome.org>
519 * debug.c (mono_debug_write_symbols): Added support for the new
522 * mono.c (main): The `--debug' argument now knows about a new
523 debugging format `mono' which will be used to display source lines
526 * debug.h (MonoDebugFormat): Added a new MONO_DEBUG_FORMAT_MONO
527 which will be used when displaying backtraces. It reads a new
530 2002-08-23 Martin Baulig <martin@gnome.org>
532 * jit.c (match_debug_method): Don't include runtime invoke methods
535 * mono.c (main): Accept `Main' as argument to --break to insert a
536 breakpoint on the application's main method.
538 2002-08-23 Martin Baulig <martin@gnome.org>
540 * debug-dwarf2.c (dwarf2_write_class_field): Don't include any static fields.
542 2002-08-21 Dietmar Maurer <dietmar@ximian.com>
544 * exception.c (arch_handle_exception): don't set stack_trace to
545 null (so that it contains the full trace even when we rethrow the
548 2002-08-19 Nick Drochak <ndrochak@gol.com>
550 * x86.brg (mono_llmult_ovf): Simplified the code greatly by refactoring
551 the algebraic form we are using. This also eliminated a silly overflow
552 of the intermediate result that was causing troubles.
554 2002-08-16 Nick Drochak <ndrochak@gol.com>
556 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers
559 2002-08-15 Nick Drochak <ndrochak@gol.com>
561 * x86.brg (mono_llmult_ovf): Fix so it throws an overflow when result
562 will not fit in 64 bits. Fixes bug #27375.
564 Wed Aug 14 17:31:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
566 * exception.c: updates for API changes in metadata/.
568 2002-08-13 Dietmar Maurer <dietmar@ximian.com>
570 * jit.c (mono_jit_init): use ((gpointer)-1) as end_of_stack
571 address for the main thread.
573 2002-08-12 Dietmar Maurer <dietmar@ximian.com>
575 * jit.c (mono_analyze_stack): added support for Thread::Abort ()
577 2002-08-08 Dietmar Maurer <dietmar@ximian.com>
579 * exception.c (arch_handle_exception): simply return and let the
580 libpthread/kernel restore the context. This should work on recent
581 versions of linuxthreads.

989 `int verbose' argument and made it public.
990 (mono_jit_compile_class): New public function, moved the code to compile
991 all methods in a class here from main().

1029 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
1030 file for all assemblies. Currently, the JIT doesn't put all methods
1031 from a single assembly into a continuous region of memory. We were
1032 previously creating valid DWARF 2 files for this, but unfortunately
1033 GDB's symbol tables get messed up when it reads more than one such file.
1035 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

1051 (mono_debug_close_assembly_stabs).
1053 * debug-dwarf2-plus.c: This is currently broken. :-(

1127 store them as 32 bit integers.
1128 (mono_analyze_stack): we need to generate a temporary var for
1129 SHL/SHR because the tree allocator can fail otherwise
1131 * exception.c (arch_handle_exception): EIP now points to the call
1132 instruction, not to the instruction after the call. This fixes the
1133 bug reported by Linus Upson (tests/exception8.cs)

1503 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1504 numbers, we still need to generate the IL offsets here. Emit line numbers
1505 for `prologue_end_offset' (the first line of actual code) and

1700 (mono_debug_open_file): Added MonoDebugFormat argument.
1701 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1702 this function from GDB. It's now safe to call this function multiple times;
1703 it'll always write a complete debugging file.
1705 * debug.c: Splitted this file into a general part which remains in this file
1706 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.

1716 now safe to call this function multiple times.
1717 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1718 returns an unique index for this type. It's used to ensure that we only write

1770 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1771 of a method and 0 otherwise.

2350 also use LDIND_XX token to load values from a specific address
2351 instead of LDLOC/STLOC.
2353 * testjit.c: use the new adressing scheme everywhere:
2354 LDIND _XX (ADDR_X), and STIND_XX (ADDR_X, tree)
