60 native code using gcc generated exception tables (-fexception).
62 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
64 * exception.c: include some code from Zoltan Varga, but modified
67 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
69 * exception.c: massive code cleanups. The code is still
70 architecture dependent, but it should be now possible to reuse the
71 complex parts for other architecture.
73 2002-11-15 Dick Porter <dick@ximian.com>
75 * jit.c: Pass the attach callback to mono_runtime_init().
77 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>

123 name of the managed file we're executing
125 2002-09-26 Martin Baulig <martin@gnome.org>
127 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
128 trampoline into the vtable, also use it for non-virtual methods,
129 remove the breakpoint when done.
131 2002-09-26 Martin Baulig <martin@gnome.org>
133 * debug.c (debug_load_method_lines): Block SIGCHLD while running
136 2002-09-26 Martin Baulig <martin@gnome.org>
138 * debug.c: Reworked the whole debugging stuff. We have now one
139 single `mono_debug_handle' which keeps a hashtable of
140 `AssemblyDebugInfo's (which may have different debugging formats).
141 The AssemblyDebugInfo is now created when the assembly is loaded,
142 but never when adding a class/type.
144 * mono.c: Initialize debugging stuff after corlib and the assembly
147 2002-09-25 Martin Baulig <martin@gnome.org>
149 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
150 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
152 (DebugMethodInfo): Removed `line_numbers'.
154 * debug.c: Reworked the line number generation; we're now using
155 the MonoDebugLineNumberEntry try for all debugging formats. This
156 type also includes the line number and IL offset, this allows the
157 JIT to produce better line number info: we only emit line number
158 information for source lines which actually have code.
160 2002-09-25 Martin Baulig <martin@gnome.org>
162 * debug.h: Removed external declaration of all functions which
163 should only be called from the Mono Debugger and also made them
164 static. Since the debugger gets their address from the
165 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
168 2002-09-25 Martin Baulig <martin@gnome.org>
170 Improved breakpoint support, we can now dynamically insert and
171 remove breakpoints at runtime and when called from withing the
172 Mono Debugger, we're using a special breakpoint trampoline.

175 whether to insert a breakpoint for a method.
176 (mono_insert_breakpoint): New method to insert a breakpoint.
177 (mono_insert_breakpoint_full): New method to insert a breakpoint,
178 takes a MonoMethodDesc.
179 (mono_remove_breakpoint): New method to remove a breakpoint.
181 * debug.c (mono_debugger_insert_breakpoint): New function for the
182 debugger. Should only be called from the debugger.
183 (mono_debugger_remove_breakpoint): Likewise.
185 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
187 * trampoline.c (get_breakpoint_trampoline): New static function to
188 create a special breakpoint trampoline for the debugger.
189 (x86_magic_trampoline): If we're running inside the Mono Debugger
190 and a breakpoint was requested for the method, generate a special
191 breakpoint trampoline.
193 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
194 to insert a breakpoint.
195 (mono_debug_last_breakpoint_address): Removed.
196 (match_debug_method): Removed, use mono_method_has_breakpoint().
198 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
200 * jit.c: reorder mono_runtime_cleanup () call since it needs the
201 engine still fully working.
203 2002-09-24 Martin Baulig <martin@gnome.org>
205 * debug.c (mono_debug_open): When we're invoked from inside the
206 Mono Debugger, set mono_debugger_class_init_func (exported in
207 metadata/class.c) to mono_add_type().
208 (mono_add_type): Call mono_debug_symfile_add_type().
210 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
212 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
213 Run finalize on domain cleanup.
214 * mono.c: call setlocale ().
215 * trampoline.c: clearer error message for invalid trampoline.
217 2002-09-21 Martin Baulig <martin@gnome.org>
219 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
220 instead of writing a byte blob.
221 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
222 (mono_debug_add_method): Incrementally add the new method to the symbol
225 * exception.c (arch_handle_exception): If we have debugging support,
226 call mono_debugger_update_symbol_file_table () as well.
228 2002-09-20 Martin Baulig <martin@gnome.org>
230 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
231 the size of the variable.
233 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
235 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
236 iterations if we visit blocks in reverse order.
238 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
240 * jit.c (mono_analyze_stack): cleaup of the array code
242 * exception.c: added patch from Julio Merno to fix bug #30048

250 2002-09-06 Martin Baulig <martin@gnome.org>
252 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
253 If you were getting random crashes when using the JIT with debugging
254 turned on, this fixes it.
256 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
258 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
260 2002-09-05 Martin Baulig <martin@gnome.org>
262 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
263 which is read by the debugger.
265 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>

277 * debug-dwarf2-plus.c: Removed.
279 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
280 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
281 `mono_symfile' to `symfile'.
283 * debug.c (mono_debug_open): Replaced the assembly argument with a
284 file name argument; you can now call this before loading the assembly.
285 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
286 we now use MonoSymbolFileLineNumberEntry's and a separate address array
287 instead; splitted out all MonoSymbolFileLineNumberEntry code into
288 debug_generate_il_offsets() and debug_update_il_offsets().
289 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
290 created when reading the symbol file or from debug_load_method_lines().
291 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
293 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before

317 * mono.c: don't use the cil-coff header outside of the loader.
319 2002-08-27 Martin Baulig <martin@gnome.org>
321 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
322 to use global variables for this since they're stored in a core file.

330 * trampoline.c (mono_generic_trampoline_code): New global variable.
331 (arch_create_jit_trampoline): Use the new global variable to store the
332 generic trampoline code instead of using a static one. This allows the
333 debugger to access this variable to check whether a method is a trampoline.
335 * debug.h (mono_generic_trampoline_code): Added external declaration.
337 2002-08-27 Martin Baulig <martin@gnome.org>
339 * debug.c (MonoDebugHandle): Moved the method hash into the
340 AssemblyDebugInfo struct since we need to use a separate hash for each
343 * debug.c: Added special undocumented command line argument to create a
344 symbol file for IL files on-the-fly. In this case, we also need to create
345 the IL files and parse them.

421 versions of linuxthreads.
423 * jit.c (mono_runtime_install_handlers): switch back to use

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

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

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

1257 we need to pass the MonoMethod pointer as first argument.
1259 * delegate.c (mono_async_invoke): notify all listeners, not only a
1261 (arch_end_invoke): we now pass a MonoMethod as first parameter and
1262 use arch_method_call_message_new() to access the stack.
1263 (arch_end_invoke): wait until we really finished processing
1264 (async_invoke_abort): notify all listeners, not only a
1267 2002-04-06 Dietmar Maurer <dietmar@ximian.com>

1319 * debug.h: Provide external declaration of `mono_debug_insert_breakpoint' and
1320 `mono_debug_last_breakpoint_address', also documented them here.

1324 * debug-private.h (MonoDebugHandle): Renamed `format' to `default_format'.
1325 (AssemblyDebugInfo): Added `format'.
1327 * debug.c: Use the AssemblyDebugInfo's `format' field to determine the format,
1328 this allows us choose the format on a per-assembly basis.
1329 (mono_debug_open_assembly): When using MONO_DEBUG_FORMAT_DWARF2_PLUS, fall back
1330 to MONO_DEBUG_FORMAT_DWARF2 if the symbol file does not exist, but the IL file

1343 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1344 numbers, we still need to generate the IL offsets here. Emit line numbers
1345 for `prologue_end_offset' (the first line of actual code) and
1346 `epilogue_begin_offset' (the line of the method's closing brace).
1347 Don't crash if cfg->bblocks [i].forest is NULL.
1348 (mono_debug_add_method): Don't crash if we don't have line numbers.
1349 Initialize the newly added fields.
1351 * debug-stabs.c: Record first and last line, emit filename info at the
1352 beginning of the stab file, gdb ignores the types otherwise.
1354 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1355 emit line number info for the first and last line.
1357 2002-03-28 Dietmar Maurer <dietmar@ximian.com>
1359 * invoke.c (arch_create_delegate_trampoline): impl.

1365 * jit.c: use opcode names from libmetadata.
1366 * debug.h, debug.c: constify char* argument.
1368 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

1388 (write_method_dwarf2): Use `minfo->method_info.this_offset' instead
1391 * debug-stabs.c (write_method_stabs): Don't generate method lines if
1392 we don't have line number information. Use `minfo->method_info.this_offset'
1393 instead of hardcoding 8.
1395 * debug.c (debug_generate_method_lines): Don't crash if we don't have
1396 line number information.

1398 MONO_DEBUG_FORMAT_DWARF2_PLUS.
1399 (mono_debug_add_method): Don't store the 'this' offset in `param_offsets',

1421 2002-03-23 Martin Baulig <martin@gnome.org>
1423 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1424 to do it before the X86_CMP.
1425 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1426 (reg: CLT (lreg, lreg)): Likewise.

1511 since GDB doesn't like Java very much.
1513 2002-03-16 Martin Baulig <martin@gnome.org>
1515 * debug-dwarf2.c: Added support for enums.
1517 2002-03-15 Martin Baulig <martin@gnome.org>

1538 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1540 (mono_debug_open_file): Added MonoDebugFormat argument.
1541 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1542 this function from GDB. It's now safe to call this function multiple times;
1543 it'll always write a complete debugging file.
1545 * debug.c: Splitted this file into a general part which remains in this file
1546 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1547 All public functions now call a corresponding format specific function.
1549 * debug.c: The following changes are private to debug.c:
1550 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1551 (record_line_number, debug_generate_method_lines): New private functions.
1552 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1553 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1554 mono_debug_open_assembly_dwarf2).
1555 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1556 now safe to call this function multiple times.
1557 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1558 returns an unique index for this type. It's used to ensure that we only write
1559 each class once to the debugging file.
1560 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1561 data structure, but don't directly write to the debugging file. This is done
1562 later from mono_debug_write_assembly().
1564 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1565 debugging output. Call mono_debug_close() on cleanup if necessary.
1567 2002-03-14 Martin Baulig <martin@gnome.org>
1569 * debug-private.h: New private header file.
1571 * debug-stabs.c: Added the stabs type generation stuff which was
1572 previously in debug.c.
1574 * debug-dwarf.c: Started to implement type support. We're currently
1575 only writing this most basic types to the dwarf file, but this will
1578 2002-03-13 Martin Baulig <martin@gnome.org>
1580 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1581 debugging code. They're now in CVS, but not yet used anywhere.
1583 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1585 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1586 macros, included new delegate code from Daniel Stodden.
1589 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1591 * jit.c: verify that corlib and runtime are in sync.
1593 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1595 * emit-x86.c, jit.c: use the debug-helpers facilities to
1596 describe and match a method when debugging.
1598 2002-03-10 Martin Baulig <martin@gnome.org>
1600 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1601 output, put a nop instruction at the start of all functions so that
1602 the adresses won't change when using --debug.
1604 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1605 the bytecode area, stabs needs a line number in the .il file. Use the
1606 new info->moffsets to get the line number.
1607 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1608 `moffsets' is an array of `total_lines' fields (total number of lines
1609 in the .il file); for each line in the .il field, this array contains
1610 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1611 of a method and 0 otherwise.
1612 (debug_load_method_lines): Read the whole .il file and initialize the
1613 info->moffsets field.
1615 2002-03-09 Martin Baulig <martin@gnome.org>
1617 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1618 the unnecessary CDQ instruction.
1620 2002-03-07 Dietmar Maurer <dietmar@ximian.com>

1623 on the runtime stack.
1625 2002-03-07 Duncan Mak <duncan@ximian.com>
