3 * exception.c: Typo fix: insinde -> inside
5 2003-01-08 Dietmar Maurer <dietmar@ximian.com>
7 * exception.c (ves_icall_get_frame_info): skip one more frame and also
8 MONO_WRAPPER_RUNTIME_INVOKE wrappers
9 (x86_unwind_native_frame): disable unnecessary assertion
11 2003-01-07 Dietmar Maurer <dietmar@ximian.com>

15 Tue Jan 7 15:15:41 CET 2003 Paolo Molaro <lupus@ximian.com>
17 * jit.c: handle wrapper_data in NEWOBJ/CALL.
19 2003-01-07 Dietmar Maurer <dietmar@ximian.com>
21 * jit.c (mono_analyze_stack): add check for NULL target in STFLD
23 2003-01-06 Martin Baulig <martin@ximian.com>
25 * debug.c (debugger_finished_mutex): Use a recursive mutex here.
27 * debug.c: Correctly handle the `debugger_finished_mutex'; it is
28 only unlocked by the pthread_cond_wait() in mono_debugger_wait().
30 2003-01-04 Jackson Harper <jackson@latitudegeo.com>
32 * debug.c: Move must_send_finished var declaration out of #if win32
33 block (this fixes the build on win32)
35 2003-01-05 Martin Baulig <martin@ximian.com>
37 * debug.c (mono_debugger_jit_exec): Custom version of mono_jit_exec();
38 this is used when we're running inside the Mono Debugger
39 (mono_debugger_wait): Put the waiting code into a function of its own.
41 * mono.c (main): Call mono_debugger_jit_exec() instead of
42 mono_jit_exec() if we're running inside the Mono Debugger.
44 2003-01-05 Martin Baulig <martin@ximian.com>
46 * debug.h (MonoDebugFormat): Added
47 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
48 we're running inside the Mono Debugger prior to the args parsing.
50 2003-01-04 Martin Baulig <martin@ximian.com>
52 * debug.c (release_symbol_file_table): Only call this if we're
53 actually modifying the symbol tables.
54 (mono_debug_open): Always set the `mono_debugger_class_init_func'
55 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
57 2003-01-03 Martin Baulig <martin@ximian.com>
59 * debug.c: Disable the mono debugger stuff on Windows.
61 2003-01-03 Martin Baulig <martin@ximian.com>
63 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
64 function. This is called from the breakpoint trampoline to signal
65 the debugger and wait until it has reload the symbol tables.
67 * trampoline.c (get_breakpoint_trampoline): Call the new
68 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
69 trampoline just before the breakpoint.
71 2002-12-31 Martin Baulig <martin@ximian.com>
73 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
74 field to point to the MonoGlobalSymbolTable.
76 2002-12-30 Martin Baulig <martin@ximian.com>
78 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
79 This variable now specifies that the symbol tables have been
80 modified after the last notification has been send. The debugger
81 uses this flag to check whether it needs to reload the symbol
83 (debugger_compile_method): Just send a notification to the
84 debugger, but don't set the modified flag. It may or may not be
85 set when the debugger gets the notification - depending on whether
86 the JIT compilation added a new method to the symbol tables.
88 2002-12-30 Martin Baulig <martin@ximian.com>
90 * debug.c (debugger_compile_method): This is a wrapper around
91 mono_compile_method() which always sends a notification to the
94 2002-12-30 Martin Baulig <martin@ximian.com>
96 * debug.c: Reload the symbol file table before sending the
97 notification event to the debugger.
98 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
100 2002-12-31 Martin Baulig <martin@ximian.com>
102 * debug.c: Propertly lock everything and avoid race conditions.
103 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.
105 2002-12-31 Duncan Mak <duncan@ximian.com>

108 declaring ret at the top of the function.
110 2002-12-30 Martin Baulig <martin@ximian.com>
112 * debug.c: When running under the mono debugger, create a special
113 debugger thread; always protect the symbol tables with a mutex.
115 2002-12-28 Martin Baulig <martin@ximian.com>
117 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
118 incremented each time one of the symbol tables is modified.
120 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
122 * jit.c: fix LDELEMA implementation here as well.
124 Wed Dec 18 11:42:58 CET 2002 Paolo Molaro <lupus@ximian.com>
126 * jit.c: handle CEE_CONV_OVF_U8_UN like CEE_CONV_OVF_I8_UN.

136 2002-12-11 Zoltan Varga <vargaz@freemail.hu>
138 * jit.c (mono_analyze_stack): call the utility function
139 mono_field_from_token to avoid code duplication.
141 2002-12-02 Dietmar Maurer <dietmar@ximian.com>
143 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
145 * x86.brg (stmt): POP floating point stack correctly
147 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
149 * emit-x86.c (arch_emit_prologue): don't save caller saved
152 * exception.c (x86_unwind_native_frame): support exceptions inside
153 native code using gcc generated exception tables (-fexception).
155 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
157 * exception.c: include some code from Zoltan Varga, but modified
160 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
162 * exception.c: massive code cleanups. The code is still
163 architecture dependent, but it should be now possible to reuse the
164 complex parts for other architecture.
166 2002-11-15 Dick Porter <dick@ximian.com>
168 * jit.c: Pass the attach callback to mono_runtime_init().
170 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
172 * jit.c: display the domain name in trace output.
174 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
176 * x86.brg (reg): fix bug #2721
178 * jit.c (mono_runtime_install_handlers): impl.
180 2002-10-17 Martin Baulig <martin@gnome.org>
182 * debug.c (mono_debug_add_method): Make this actually work if we don't
183 have any lifetime information.
185 2002-10-15 Martin Baulig <martin@gnome.org>
187 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
189 * debug.c (generate_line_number): Small fix to make this actually
190 work for more complex things.
192 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
194 * x86.brg (freg): use fprem instead of fprem1
196 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
198 * jit.c (ves_array_element_address): added check for out of range index

209 2002-09-27 Martin Baulig <martin@gnome.org>
211 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
213 2002-09-27 Dick Porter <dick@ximian.com>
215 * mono.c: Tell glib what the program name is, by passing it the
216 name of the managed file we're executing
218 2002-09-26 Martin Baulig <martin@gnome.org>
220 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
221 trampoline into the vtable, also use it for non-virtual methods,
222 remove the breakpoint when done.
224 2002-09-26 Martin Baulig <martin@gnome.org>
226 * debug.c (debug_load_method_lines): Block SIGCHLD while running
229 2002-09-26 Martin Baulig <martin@gnome.org>
231 * debug.c: Reworked the whole debugging stuff. We have now one
232 single `mono_debug_handle' which keeps a hashtable of
233 `AssemblyDebugInfo's (which may have different debugging formats).
234 The AssemblyDebugInfo is now created when the assembly is loaded,
235 but never when adding a class/type.
237 * mono.c: Initialize debugging stuff after corlib and the assembly
240 2002-09-25 Martin Baulig <martin@gnome.org>
242 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
243 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
245 (DebugMethodInfo): Removed `line_numbers'.
247 * debug.c: Reworked the line number generation; we're now using
248 the MonoDebugLineNumberEntry try for all debugging formats. This
249 type also includes the line number and IL offset, this allows the
250 JIT to produce better line number info: we only emit line number
251 information for source lines which actually have code.
253 2002-09-25 Martin Baulig <martin@gnome.org>
255 * debug.h: Removed external declaration of all functions which
256 should only be called from the Mono Debugger and also made them
257 static. Since the debugger gets their address from the
258 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
261 2002-09-25 Martin Baulig <martin@gnome.org>
263 Improved breakpoint support, we can now dynamically insert and
264 remove breakpoints at runtime and when called from withing the
265 Mono Debugger, we're using a special breakpoint trampoline.
267 * debug.h (mono_method_has_breakpoint): New method to check
268 whether to insert a breakpoint for a method.
269 (mono_insert_breakpoint): New method to insert a breakpoint.
270 (mono_insert_breakpoint_full): New method to insert a breakpoint,
271 takes a MonoMethodDesc.
272 (mono_remove_breakpoint): New method to remove a breakpoint.
274 * debug.c (mono_debugger_insert_breakpoint): New function for the
275 debugger. Should only be called from the debugger.
276 (mono_debugger_remove_breakpoint): Likewise.
278 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
280 * trampoline.c (get_breakpoint_trampoline): New static function to
281 create a special breakpoint trampoline for the debugger.
282 (x86_magic_trampoline): If we're running inside the Mono Debugger
283 and a breakpoint was requested for the method, generate a special
284 breakpoint trampoline.
286 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
287 to insert a breakpoint.
288 (mono_debug_last_breakpoint_address): Removed.
289 (match_debug_method): Removed, use mono_method_has_breakpoint().
291 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
293 * jit.c: reorder mono_runtime_cleanup () call since it needs the
294 engine still fully working.
296 2002-09-24 Martin Baulig <martin@gnome.org>
298 * debug.c (mono_debug_open): When we're invoked from inside the
299 Mono Debugger, set mono_debugger_class_init_func (exported in
300 metadata/class.c) to mono_add_type().
301 (mono_add_type): Call mono_debug_symfile_add_type().
303 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
305 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
306 Run finalize on domain cleanup.
307 * mono.c: call setlocale ().
308 * trampoline.c: clearer error message for invalid trampoline.
310 2002-09-21 Martin Baulig <martin@gnome.org>
312 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
313 instead of writing a byte blob.
314 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
315 (mono_debug_add_method): Incrementally add the new method to the symbol
318 * exception.c (arch_handle_exception): If we have debugging support,
319 call mono_debugger_update_symbol_file_table () as well.
321 2002-09-20 Martin Baulig <martin@gnome.org>
323 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
324 the size of the variable.
326 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
328 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
329 iterations if we visit blocks in reverse order.
331 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
333 * jit.c (mono_analyze_stack): cleaup of the array code
335 * exception.c: added patch from Julio Merno to fix bug #30048
337 * jit.c (mono_analyze_stack): code cleanup, fix bug #29365
339 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
341 * x86.brg (LDELEMA): use x86_lea
343 2002-09-06 Martin Baulig <martin@gnome.org>
345 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
346 If you were getting random crashes when using the JIT with debugging
347 turned on, this fixes it.
349 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
351 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
353 2002-09-05 Martin Baulig <martin@gnome.org>
355 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
356 which is read by the debugger.
358 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>
360 * Makefile.am: link libmono directly into mono. Use a ld script
361 to reduce exported symbols.
363 2002-09-03 Martin Baulig <martin@gnome.org>
365 * debug.c (free_method_info): Make this actually work.
367 2002-09-03 Martin Baulig <martin@gnome.org>
369 * debug.h (MonoDebugFormat): Killed MONO_DEBUG_FORMAT_DWARF2_PLUS.
370 * debug-dwarf2-plus.c: Removed.
372 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
373 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
374 `mono_symfile' to `symfile'.
376 * debug.c (mono_debug_open): Replaced the assembly argument with a
377 file name argument; you can now call this before loading the assembly.
378 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
379 we now use MonoSymbolFileLineNumberEntry's and a separate address array
380 instead; splitted out all MonoSymbolFileLineNumberEntry code into
381 debug_generate_il_offsets() and debug_update_il_offsets().
382 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
383 created when reading the symbol file or from debug_load_method_lines().
384 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
386 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before
387 looking up an address.
389 * debug.c: Don't create the .il files for MONO_DEBUG_FORMAT_MONO.
391 * mono.c (main): Initialize debugging before loading the first assembly.

403 2002-08-27 Martin Baulig <martin@gnome.org>
405 * debug.c: The mono symbol file is installed together with the assembly
406 it belongs to and it's used on a per-image basis.
408 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
410 * mono.c: don't use the cil-coff header outside of the loader.
412 2002-08-27 Martin Baulig <martin@gnome.org>
414 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
415 to use global variables for this since they're stored in a core file.
416 (mono_debugger_symbol_file_table_generation): New global variable.
417 (mono_debugger_symbol_file_table): New global variable.
418 (mono_debugger_update_symbol_file_table): New global function to update
419 the symbol file table.

423 * trampoline.c (mono_generic_trampoline_code): New global variable.
424 (arch_create_jit_trampoline): Use the new global variable to store the
425 generic trampoline code instead of using a static one. This allows the
426 debugger to access this variable to check whether a method is a trampoline.
428 * debug.h (mono_generic_trampoline_code): Added external declaration.
430 2002-08-27 Martin Baulig <martin@gnome.org>
432 * debug.c (MonoDebugHandle): Moved the method hash into the
433 AssemblyDebugInfo struct since we need to use a separate hash for each
436 * debug.c: Added special undocumented command line argument to create a
437 symbol file for IL files on-the-fly. In this case, we also need to create
438 the IL files and parse them.
439 (mono_debugger_internal_get_symbol_files): Return something more reasonable.
441 2002-08-26 Martin Baulig <martin@gnome.org>
443 * debug.c (mono_debugger_internal_free_symbol_files): New function.

450 2002-08-24 Martin Baulig <martin@gnome.org>
452 * debug.c (mono_debug_write_symbols): Added support for the new
455 * mono.c (main): The `--debug' argument now knows about a new
456 debugging format `mono' which will be used to display source lines
459 * debug.h (MonoDebugFormat): Added a new MONO_DEBUG_FORMAT_MONO
460 which will be used when displaying backtraces. It reads a new
463 2002-08-23 Martin Baulig <martin@gnome.org>
465 * jit.c (match_debug_method): Don't include runtime invoke methods
468 * mono.c (main): Accept `Main' as argument to --break to insert a

478 null (so that it contains the full trace even when we rethrow the
481 2002-08-19 Nick Drochak <ndrochak@gol.com>
483 * x86.brg (mono_llmult_ovf): Simplified the code greatly by refactoring
484 the algebraic form we are using. This also eliminated a silly overflow
485 of the intermediate result that was causing troubles.
487 2002-08-16 Nick Drochak <ndrochak@gol.com>
489 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers
492 2002-08-15 Nick Drochak <ndrochak@gol.com>
494 * x86.brg (mono_llmult_ovf): Fix so it throws an overflow when result
495 will not fit in 64 bits. Fixes bug #27375.
497 Wed Aug 14 17:31:37 CEST 2002 Paolo Molaro <lupus@ximian.com>

510 2002-08-08 Dietmar Maurer <dietmar@ximian.com>
512 * exception.c (arch_handle_exception): simply return and let the
513 libpthread/kernel restore the context. This should work on recent
514 versions of linuxthreads.
516 * jit.c (mono_runtime_install_handlers): switch back to use
517 sigaction from libpthreads. As long as this does not make problems
518 we should use this instead of syscall.
520 2002-08-07 Dietmar Maurer <dietmar@ximian.com>
522 * jit.c: removed the createdelegate icall
523 (mono_analyze_stack): special case Array::Address()
525 2002-08-06 Dietmar Maurer <dietmar@ximian.com>

528 mono_get_lmf_addr relocatable.
529 (arch_jit_compile_cfg): do not waste memory
530 (arch_jit_compile_cfg): use a mempool to store native code. This
531 improves locality of code.
533 2002-08-01 Dietmar Maurer <dietmar@ximian.com>
535 * jit.c (mono_analyze_stack): impl. CEE_MONO_RETOBJ
537 2002-07-30 Sergey Chaban <serge@wildwestsoftware.com>
539 * x86.brg (LOCALLOC): under Windows, if allocation size is bigger
540 than one page, it's necessary to allocate memory incrementally,
541 in page-size steps, performing stack-touch every time.
542 Also added LOCALLOC(CONST_I4) implementation.
544 2002-07-27 Dietmar Maurer <dietmar@ximian.com>
546 * jit.c (mono_get_runtime_method): code cleanup
548 * x86.brg: we do not need to save EAX/ECX/EDX in stmt:
550 2002-07-24 Dietmar Maurer <dietmar@ximian.com>
552 * jit.c (mono_analyze_stack): added CEE_TAIL (but it is ignored)
554 Wed Jul 24 13:02:50 CEST 2002 Paolo Molaro <lupus@ximian.com>

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

1355 use arch_method_call_message_new() to access the stack.
1356 (arch_end_invoke): wait until we really finished processing
1357 (async_invoke_abort): notify all listeners, not only a
1360 2002-04-06 Dietmar Maurer <dietmar@ximian.com>

1436 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1437 numbers, we still need to generate the IL offsets here. Emit line numbers
1438 for `prologue_end_offset' (the first line of actual code) and
1439 `epilogue_begin_offset' (the line of the method's closing brace).
1440 Don't crash if cfg->bblocks [i].forest is NULL.
1441 (mono_debug_add_method): Don't crash if we don't have line numbers.
1442 Initialize the newly added fields.
1444 * debug-stabs.c: Record first and last line, emit filename info at the

1447 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1448 emit line number info for the first and last line.
1450 2002-03-28 Dietmar Maurer <dietmar@ximian.com>
1452 * invoke.c (arch_create_delegate_trampoline): impl.

1484 * debug-stabs.c (write_method_stabs): Don't generate method lines if
1485 we don't have line number information. Use `minfo->method_info.this_offset'
1486 instead of hardcoding 8.

1514 2002-03-23 Martin Baulig <martin@gnome.org>
1516 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1517 to do it before the X86_CMP.
1518 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1519 (reg: CLT (lreg, lreg)): Likewise.

1598 2002-03-16 Martin Baulig <martin@gnome.org>
1600 * debug.c (mono_debug_get_type): Recursively call this for all members and
1601 parent classes of a class type.
1603 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1604 since GDB doesn't like Java very much.
1606 2002-03-16 Martin Baulig <martin@gnome.org>
1608 * debug-dwarf2.c: Added support for enums.
1610 2002-03-15 Martin Baulig <martin@gnome.org>

1631 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1633 (mono_debug_open_file): Added MonoDebugFormat argument.
1634 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1635 this function from GDB. It's now safe to call this function multiple times;
1636 it'll always write a complete debugging file.
1638 * debug.c: Splitted this file into a general part which remains in this file
1639 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1640 All public functions now call a corresponding format specific function.
1642 * debug.c: The following changes are private to debug.c:
1643 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1644 (record_line_number, debug_generate_method_lines): New private functions.
1645 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1646 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1647 mono_debug_open_assembly_dwarf2).
1648 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1649 now safe to call this function multiple times.
1650 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1651 returns an unique index for this type. It's used to ensure that we only write
1652 each class once to the debugging file.
1653 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1654 data structure, but don't directly write to the debugging file. This is done
1655 later from mono_debug_write_assembly().
1657 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1658 debugging output. Call mono_debug_close() on cleanup if necessary.
1660 2002-03-14 Martin Baulig <martin@gnome.org>
1662 * debug-private.h: New private header file.
1664 * debug-stabs.c: Added the stabs type generation stuff which was
1665 previously in debug.c.
1667 * debug-dwarf.c: Started to implement type support. We're currently
1668 only writing this most basic types to the dwarf file, but this will
1671 2002-03-13 Martin Baulig <martin@gnome.org>
1673 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1674 debugging code. They're now in CVS, but not yet used anywhere.
1676 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1678 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1679 macros, included new delegate code from Daniel Stodden.
1682 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1684 * jit.c: verify that corlib and runtime are in sync.
1686 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1688 * emit-x86.c, jit.c: use the debug-helpers facilities to
1689 describe and match a method when debugging.
1691 2002-03-10 Martin Baulig <martin@gnome.org>
1693 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1694 output, put a nop instruction at the start of all functions so that
1695 the adresses won't change when using --debug.
1697 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1698 the bytecode area, stabs needs a line number in the .il file. Use the
1699 new info->moffsets to get the line number.
1700 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1701 `moffsets' is an array of `total_lines' fields (total number of lines
1702 in the .il file); for each line in the .il field, this array contains
1703 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1704 of a method and 0 otherwise.
1705 (debug_load_method_lines): Read the whole .il file and initialize the
1706 info->moffsets field.
1708 2002-03-09 Martin Baulig <martin@gnome.org>
1710 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1711 the unnecessary CDQ instruction.
1713 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1715 * jit.c (mono_analyze_stack): only load addresses of value types
1716 on the runtime stack.

2357 * testjit.c (mono_compile_method): Provide better error reporting.
2359 2001-09-17 Dietmar Maurer <dietmar@ximian.com>
2361 * testjit.c (tree_get_address): impl. to fix address bug
2362 (tree_get_address): make sure that we can only jump to the first
2363 instruction of a tree.
2365 * x86.brg: emit real code for calls
2367 * testjit.c (create_jit_trampoline): creates a function to trigger jit
2369 (mono_compile_method): reversed argument order
2371 2001-09-15 Dietmar Maurer <dietmar@ximian.com>
2373 * x86.brg (stmt): don't emit unnecessary register moves

2379 * x86.brg: branch addresses are now resolved
2381 * testjit.c (compute_branches): compute address of branches
2383 * x86.brg: emit real x86 instructions
2385 * testjit.c: call objdump to disassemble the output
2387 2001-09-13 Dietmar Maurer <dietmar@ximian.com>
2389 * x86.brg: use the right offsets to access local variables
2392 * emit-x86.c: only save/restore callee saved registers if they are
2395 * testjit.c (tree_allocate_regs): use the new MonoRegSet to
2397 (mono_compile_method): changed the tree for mothod calls
2404 2001-09-10 Miguel de Icaza <miguel@ximian.com>
2406 * x86.brg: Use Unix assembly syntax.
