39 native code using gcc generated exception tables (-fexception).
41 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
43 * exception.c: include some code from Zoltan Varga, but modified
46 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
48 * exception.c: massive code cleanups. The code is still
49 architecture dependent, but it should be now possible to reuse the
50 complex parts for other architecture.
52 2002-11-15 Dick Porter <dick@ximian.com>
54 * jit.c: Pass the attach callback to mono_runtime_init().
56 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
58 * jit.c: display the domain name in trace output.
60 2002-11-08 Dietmar Maurer <dietmar@ximian.com>

99 2002-09-27 Dick Porter <dick@ximian.com>
101 * mono.c: Tell glib what the program name is, by passing it the
102 name of the managed file we're executing
104 2002-09-26 Martin Baulig <martin@gnome.org>
106 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
107 trampoline into the vtable, also use it for non-virtual methods,
108 remove the breakpoint when done.
110 2002-09-26 Martin Baulig <martin@gnome.org>
112 * debug.c (debug_load_method_lines): Block SIGCHLD while running
115 2002-09-26 Martin Baulig <martin@gnome.org>
117 * debug.c: Reworked the whole debugging stuff. We have now one
118 single `mono_debug_handle' which keeps a hashtable of
119 `AssemblyDebugInfo's (which may have different debugging formats).
120 The AssemblyDebugInfo is now created when the assembly is loaded,
121 but never when adding a class/type.
123 * mono.c: Initialize debugging stuff after corlib and the assembly
126 2002-09-25 Martin Baulig <martin@gnome.org>
128 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
129 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
131 (DebugMethodInfo): Removed `line_numbers'.
133 * debug.c: Reworked the line number generation; we're now using
134 the MonoDebugLineNumberEntry try for all debugging formats. This
135 type also includes the line number and IL offset, this allows the
136 JIT to produce better line number info: we only emit line number
137 information for source lines which actually have code.
139 2002-09-25 Martin Baulig <martin@gnome.org>
141 * debug.h: Removed external declaration of all functions which
142 should only be called from the Mono Debugger and also made them
143 static. Since the debugger gets their address from the
144 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
147 2002-09-25 Martin Baulig <martin@gnome.org>
149 Improved breakpoint support, we can now dynamically insert and
150 remove breakpoints at runtime and when called from withing the
151 Mono Debugger, we're using a special breakpoint trampoline.
153 * debug.h (mono_method_has_breakpoint): New method to check
154 whether to insert a breakpoint for a method.
155 (mono_insert_breakpoint): New method to insert a breakpoint.
156 (mono_insert_breakpoint_full): New method to insert a breakpoint,
157 takes a MonoMethodDesc.
158 (mono_remove_breakpoint): New method to remove a breakpoint.
160 * debug.c (mono_debugger_insert_breakpoint): New function for the
161 debugger. Should only be called from the debugger.
162 (mono_debugger_remove_breakpoint): Likewise.
164 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
166 * trampoline.c (get_breakpoint_trampoline): New static function to
167 create a special breakpoint trampoline for the debugger.
168 (x86_magic_trampoline): If we're running inside the Mono Debugger
169 and a breakpoint was requested for the method, generate a special
170 breakpoint trampoline.
172 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
173 to insert a breakpoint.
174 (mono_debug_last_breakpoint_address): Removed.
175 (match_debug_method): Removed, use mono_method_has_breakpoint().
177 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
179 * jit.c: reorder mono_runtime_cleanup () call since it needs the
180 engine still fully working.
182 2002-09-24 Martin Baulig <martin@gnome.org>
184 * debug.c (mono_debug_open): When we're invoked from inside the
185 Mono Debugger, set mono_debugger_class_init_func (exported in
186 metadata/class.c) to mono_add_type().
187 (mono_add_type): Call mono_debug_symfile_add_type().
189 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
191 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
192 Run finalize on domain cleanup.
193 * mono.c: call setlocale ().
194 * trampoline.c: clearer error message for invalid trampoline.
196 2002-09-21 Martin Baulig <martin@gnome.org>
198 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
199 instead of writing a byte blob.
200 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
201 (mono_debug_add_method): Incrementally add the new method to the symbol
204 * exception.c (arch_handle_exception): If we have debugging support,
205 call mono_debugger_update_symbol_file_table () as well.
207 2002-09-20 Martin Baulig <martin@gnome.org>
209 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
210 the size of the variable.
212 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
214 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
215 iterations if we visit blocks in reverse order.
217 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
219 * jit.c (mono_analyze_stack): cleaup of the array code
221 * exception.c: added patch from Julio Merno to fix bug #30048
223 * jit.c (mono_analyze_stack): code cleanup, fix bug #29365
225 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
227 * x86.brg (LDELEMA): use x86_lea
229 2002-09-06 Martin Baulig <martin@gnome.org>
231 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
232 If you were getting random crashes when using the JIT with debugging
233 turned on, this fixes it.
235 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
237 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
239 2002-09-05 Martin Baulig <martin@gnome.org>
241 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
242 which is read by the debugger.
244 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>

256 * debug-dwarf2-plus.c: Removed.
258 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
259 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
260 `mono_symfile' to `symfile'.
262 * debug.c (mono_debug_open): Replaced the assembly argument with a
263 file name argument; you can now call this before loading the assembly.
264 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
265 we now use MonoSymbolFileLineNumberEntry's and a separate address array
266 instead; splitted out all MonoSymbolFileLineNumberEntry code into
267 debug_generate_il_offsets() and debug_update_il_offsets().
268 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
269 created when reading the symbol file or from debug_load_method_lines().
270 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
272 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before

291 * debug.c: The mono symbol file is installed together with the assembly
292 it belongs to and it's used on a per-image basis.
294 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
296 * mono.c: don't use the cil-coff header outside of the loader.
298 2002-08-27 Martin Baulig <martin@gnome.org>
300 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
301 to use global variables for this since they're stored in a core file.

309 * trampoline.c (mono_generic_trampoline_code): New global variable.
310 (arch_create_jit_trampoline): Use the new global variable to store the
311 generic trampoline code instead of using a static one. This allows the
312 debugger to access this variable to check whether a method is a trampoline.
314 * debug.h (mono_generic_trampoline_code): Added external declaration.
316 2002-08-27 Martin Baulig <martin@gnome.org>
318 * debug.c (MonoDebugHandle): Moved the method hash into the
319 AssemblyDebugInfo struct since we need to use a separate hash for each
322 * debug.c: Added special undocumented command line argument to create a
323 symbol file for IL files on-the-fly. In this case, we also need to create
324 the IL files and parse them.

400 versions of linuxthreads.
402 * jit.c (mono_runtime_install_handlers): switch back to use

426 than one page, it's necessary to allocate memory incrementally,
427 in page-size steps, performing stack-touch every time.
428 Also added LOCALLOC(CONST_I4) implementation.

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

1236 we need to pass the MonoMethod pointer as first argument.
1238 * delegate.c (mono_async_invoke): notify all listeners, not only a
1240 (arch_end_invoke): we now pass a MonoMethod as first parameter and
1241 use arch_method_call_message_new() to access the stack.
1242 (arch_end_invoke): wait until we really finished processing
1243 (async_invoke_abort): notify all listeners, not only a
1246 2002-04-06 Dietmar Maurer <dietmar@ximian.com>

1303 * debug-private.h (MonoDebugHandle): Renamed `format' to `default_format'.
1304 (AssemblyDebugInfo): Added `format'.
1306 * debug.c: Use the AssemblyDebugInfo's `format' field to determine the format,
1307 this allows us choose the format on a per-assembly basis.

1322 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1323 numbers, we still need to generate the IL offsets here. Emit line numbers
1324 for `prologue_end_offset' (the first line of actual code) and
1325 `epilogue_begin_offset' (the line of the method's closing brace).
1326 Don't crash if cfg->bblocks [i].forest is NULL.
1327 (mono_debug_add_method): Don't crash if we don't have line numbers.
1328 Initialize the newly added fields.
1330 * debug-stabs.c: Record first and last line, emit filename info at the
1331 beginning of the stab file, gdb ignores the types otherwise.
1333 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1334 emit line number info for the first and last line.
1336 2002-03-28 Dietmar Maurer <dietmar@ximian.com>
1338 * invoke.c (arch_create_delegate_trampoline): impl.

1345 * debug.h, debug.c: constify char* argument.
1347 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

1366 lines if we don't have line number information.
1367 (write_method_dwarf2): Use `minfo->method_info.this_offset' instead
1370 * debug-stabs.c (write_method_stabs): Don't generate method lines if
1371 we don't have line number information. Use `minfo->method_info.this_offset'
1372 instead of hardcoding 8.
1374 * debug.c (debug_generate_method_lines): Don't crash if we don't have
1375 line number information.

1395 2002-03-24 Martin Baulig <martin@gnome.org>
1397 * debug.c (mono_debug_add_method): Include the `this' offset in
1398 the `minfo->method_info.param_offsets' array.
1400 2002-03-23 Martin Baulig <martin@gnome.org>
1402 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1403 to do it before the X86_CMP.
1404 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1405 (reg: CLT (lreg, lreg)): Likewise.

1436 removed everything which is already in MonoDebugMethodInfo.
1438 * debug.c (debug_generate_method_lines): Generate the MonoILOffsetInfo array.

1477 * debug.c (mono_debug_get_type): Recursively call this for all function members
1479 (mono_debug_add_method): Don't mangle function names, this must be done by the
1480 debugger backend if the debugging format needs mangled names.
1482 * debug-dwarf2.c: Improved support for classes, added member functions.
1484 2002-03-16 Martin Baulig <martin@gnome.org>
1486 * debug.c (mono_debug_get_type): Recursively call this for all members and
1487 parent classes of a class type.
1489 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1490 since GDB doesn't like Java very much.
1492 2002-03-16 Martin Baulig <martin@gnome.org>
1494 * debug-dwarf2.c: Added support for enums.
1496 2002-03-15 Martin Baulig <martin@gnome.org>

1517 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1519 (mono_debug_open_file): Added MonoDebugFormat argument.
1520 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1521 this function from GDB. It's now safe to call this function multiple times;
1522 it'll always write a complete debugging file.
1524 * debug.c: Splitted this file into a general part which remains in this file
1525 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1526 All public functions now call a corresponding format specific function.
1528 * debug.c: The following changes are private to debug.c:
1529 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1530 (record_line_number, debug_generate_method_lines): New private functions.
1531 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1532 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1533 mono_debug_open_assembly_dwarf2).
1534 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1535 now safe to call this function multiple times.
1536 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1537 returns an unique index for this type. It's used to ensure that we only write
1538 each class once to the debugging file.
1539 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1540 data structure, but don't directly write to the debugging file. This is done
1541 later from mono_debug_write_assembly().
1543 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1544 debugging output. Call mono_debug_close() on cleanup if necessary.
1546 2002-03-14 Martin Baulig <martin@gnome.org>
1548 * debug-private.h: New private header file.
1550 * debug-stabs.c: Added the stabs type generation stuff which was
1551 previously in debug.c.
1553 * debug-dwarf.c: Started to implement type support. We're currently
1554 only writing this most basic types to the dwarf file, but this will
1557 2002-03-13 Martin Baulig <martin@gnome.org>
1559 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1560 debugging code. They're now in CVS, but not yet used anywhere.
1562 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1564 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1565 macros, included new delegate code from Daniel Stodden.
1568 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1570 * jit.c: verify that corlib and runtime are in sync.
1572 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1574 * emit-x86.c, jit.c: use the debug-helpers facilities to
1575 describe and match a method when debugging.
1577 2002-03-10 Martin Baulig <martin@gnome.org>
1579 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1580 output, put a nop instruction at the start of all functions so that
1581 the adresses won't change when using --debug.
1583 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1584 the bytecode area, stabs needs a line number in the .il file. Use the
1585 new info->moffsets to get the line number.
1586 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1587 `moffsets' is an array of `total_lines' fields (total number of lines
1588 in the .il file); for each line in the .il field, this array contains
1589 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1590 of a method and 0 otherwise.
1591 (debug_load_method_lines): Read the whole .il file and initialize the
1592 info->moffsets field.
1594 2002-03-09 Martin Baulig <martin@gnome.org>
1596 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1597 the unnecessary CDQ instruction.
1599 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
