3 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
4 field to point to the MonoGlobalSymbolTable.
6 2002-12-30 Martin Baulig <martin@ximian.com>
8 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
9 This variable now specifies that the symbol tables have been
10 modified after the last notification has been send. The debugger
11 uses this flag to check whether it needs to reload the symbol
13 (debugger_compile_method): Just send a notification to the
14 debugger, but don't set the modified flag. It may or may not be
15 set when the debugger gets the notification - depending on whether
16 the JIT compilation added a new method to the symbol tables.
18 2002-12-30 Martin Baulig <martin@ximian.com>
20 * debug.c (debugger_compile_method): This is a wrapper around
21 mono_compile_method() which always sends a notification to the
24 2002-12-30 Martin Baulig <martin@ximian.com>
26 * debug.c: Reload the symbol file table before sending the
27 notification event to the debugger.

38 declaring ret at the top of the function.
40 2002-12-30 Martin Baulig <martin@ximian.com>
42 * debug.c: When running under the mono debugger, create a special
43 debugger thread; always protect the symbol tables with a mutex.
45 2002-12-28 Martin Baulig <martin@ximian.com>
47 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
48 incremented each time one of the symbol tables is modified.
50 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
52 * jit.c: fix LDELEMA implementation here as well.

83 native code using gcc generated exception tables (-fexception).
85 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
87 * exception.c: include some code from Zoltan Varga, but modified
90 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
92 * exception.c: massive code cleanups. The code is still
93 architecture dependent, but it should be now possible to reuse the
94 complex parts for other architecture.
96 2002-11-15 Dick Porter <dick@ximian.com>
98 * jit.c: Pass the attach callback to mono_runtime_init().
100 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>

146 name of the managed file we're executing
148 2002-09-26 Martin Baulig <martin@gnome.org>
150 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
151 trampoline into the vtable, also use it for non-virtual methods,
152 remove the breakpoint when done.
154 2002-09-26 Martin Baulig <martin@gnome.org>
156 * debug.c (debug_load_method_lines): Block SIGCHLD while running
159 2002-09-26 Martin Baulig <martin@gnome.org>
161 * debug.c: Reworked the whole debugging stuff. We have now one
162 single `mono_debug_handle' which keeps a hashtable of
163 `AssemblyDebugInfo's (which may have different debugging formats).
164 The AssemblyDebugInfo is now created when the assembly is loaded,
165 but never when adding a class/type.
167 * mono.c: Initialize debugging stuff after corlib and the assembly
170 2002-09-25 Martin Baulig <martin@gnome.org>
172 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
173 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
175 (DebugMethodInfo): Removed `line_numbers'.
177 * debug.c: Reworked the line number generation; we're now using
178 the MonoDebugLineNumberEntry try for all debugging formats. This
179 type also includes the line number and IL offset, this allows the
180 JIT to produce better line number info: we only emit line number
181 information for source lines which actually have code.
183 2002-09-25 Martin Baulig <martin@gnome.org>
185 * debug.h: Removed external declaration of all functions which
186 should only be called from the Mono Debugger and also made them
187 static. Since the debugger gets their address from the
188 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
191 2002-09-25 Martin Baulig <martin@gnome.org>
193 Improved breakpoint support, we can now dynamically insert and
194 remove breakpoints at runtime and when called from withing the
195 Mono Debugger, we're using a special breakpoint trampoline.
197 * debug.h (mono_method_has_breakpoint): New method to check
198 whether to insert a breakpoint for a method.
199 (mono_insert_breakpoint): New method to insert a breakpoint.
200 (mono_insert_breakpoint_full): New method to insert a breakpoint,
201 takes a MonoMethodDesc.
202 (mono_remove_breakpoint): New method to remove a breakpoint.
204 * debug.c (mono_debugger_insert_breakpoint): New function for the
205 debugger. Should only be called from the debugger.
206 (mono_debugger_remove_breakpoint): Likewise.
208 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
210 * trampoline.c (get_breakpoint_trampoline): New static function to
211 create a special breakpoint trampoline for the debugger.
212 (x86_magic_trampoline): If we're running inside the Mono Debugger
213 and a breakpoint was requested for the method, generate a special
214 breakpoint trampoline.
216 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
217 to insert a breakpoint.
218 (mono_debug_last_breakpoint_address): Removed.
219 (match_debug_method): Removed, use mono_method_has_breakpoint().
221 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
223 * jit.c: reorder mono_runtime_cleanup () call since it needs the
224 engine still fully working.
226 2002-09-24 Martin Baulig <martin@gnome.org>
228 * debug.c (mono_debug_open): When we're invoked from inside the
229 Mono Debugger, set mono_debugger_class_init_func (exported in
230 metadata/class.c) to mono_add_type().
231 (mono_add_type): Call mono_debug_symfile_add_type().
233 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
235 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
236 Run finalize on domain cleanup.
237 * mono.c: call setlocale ().
238 * trampoline.c: clearer error message for invalid trampoline.
240 2002-09-21 Martin Baulig <martin@gnome.org>
242 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
243 instead of writing a byte blob.
244 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
245 (mono_debug_add_method): Incrementally add the new method to the symbol
248 * exception.c (arch_handle_exception): If we have debugging support,
249 call mono_debugger_update_symbol_file_table () as well.
251 2002-09-20 Martin Baulig <martin@gnome.org>
253 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
254 the size of the variable.
256 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
258 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
259 iterations if we visit blocks in reverse order.
261 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
263 * jit.c (mono_analyze_stack): cleaup of the array code
265 * exception.c: added patch from Julio Merno to fix bug #30048

273 2002-09-06 Martin Baulig <martin@gnome.org>
275 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
276 If you were getting random crashes when using the JIT with debugging
277 turned on, this fixes it.
279 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
281 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
283 2002-09-05 Martin Baulig <martin@gnome.org>
285 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
286 which is read by the debugger.
288 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>

300 * debug-dwarf2-plus.c: Removed.
302 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
303 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
304 `mono_symfile' to `symfile'.
306 * debug.c (mono_debug_open): Replaced the assembly argument with a
307 file name argument; you can now call this before loading the assembly.
308 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
309 we now use MonoSymbolFileLineNumberEntry's and a separate address array
310 instead; splitted out all MonoSymbolFileLineNumberEntry code into
311 debug_generate_il_offsets() and debug_update_il_offsets().
312 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
313 created when reading the symbol file or from debug_load_method_lines().
314 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
316 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before

335 * debug.c: The mono symbol file is installed together with the assembly
336 it belongs to and it's used on a per-image basis.
338 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
340 * mono.c: don't use the cil-coff header outside of the loader.
342 2002-08-27 Martin Baulig <martin@gnome.org>
344 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
345 to use global variables for this since they're stored in a core file.

354 (arch_create_jit_trampoline): Use the new global variable to store the
355 generic trampoline code instead of using a static one. This allows the
356 debugger to access this variable to check whether a method is a trampoline.
358 * debug.h (mono_generic_trampoline_code): Added external declaration.
360 2002-08-27 Martin Baulig <martin@gnome.org>
362 * debug.c (MonoDebugHandle): Moved the method hash into the
363 AssemblyDebugInfo struct since we need to use a separate hash for each
366 * debug.c: Added special undocumented command line argument to create a
367 symbol file for IL files on-the-fly. In this case, we also need to create
368 the IL files and parse them.

386 debugging format `mono' which will be used to display source lines
389 * debug.h (MonoDebugFormat): Added a new MONO_DEBUG_FORMAT_MONO
390 which will be used when displaying backtraces. It reads a new

415 of the intermediate result that was causing troubles.
417 2002-08-16 Nick Drochak <ndrochak@gol.com>
419 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers

440 2002-08-08 Dietmar Maurer <dietmar@ximian.com>
442 * exception.c (arch_handle_exception): simply return and let the
443 libpthread/kernel restore the context. This should work on recent
444 versions of linuxthreads.
446 * jit.c (mono_runtime_install_handlers): switch back to use
447 sigaction from libpthreads. As long as this does not make problems
448 we should use this instead of syscall.

467 2002-07-30 Sergey Chaban <serge@wildwestsoftware.com>
469 * x86.brg (LOCALLOC): under Windows, if allocation size is bigger
470 than one page, it's necessary to allocate memory incrementally,
471 in page-size steps, performing stack-touch every time.
472 Also added LOCALLOC(CONST_I4) implementation.
474 2002-07-27 Dietmar Maurer <dietmar@ximian.com>
476 * jit.c (mono_get_runtime_method): code cleanup

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

994 * exception.c (arch_handle_exception): EIP now points to the call
995 instruction, not to the instruction after the call. This fixes the
996 bug reported by Linus Upson (tests/exception8.cs)

1285 use arch_method_call_message_new() to access the stack.
1286 (arch_end_invoke): wait until we really finished processing
1287 (async_invoke_abort): notify all listeners, not only a
1290 2002-04-06 Dietmar Maurer <dietmar@ximian.com>

1347 * debug-private.h (MonoDebugHandle): Renamed `format' to `default_format'.
1348 (AssemblyDebugInfo): Added `format'.
1350 * debug.c: Use the AssemblyDebugInfo's `format' field to determine the format,
1351 this allows us choose the format on a per-assembly basis.

1366 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1367 numbers, we still need to generate the IL offsets here. Emit line numbers
1368 for `prologue_end_offset' (the first line of actual code) and
1369 `epilogue_begin_offset' (the line of the method's closing brace).
1370 Don't crash if cfg->bblocks [i].forest is NULL.
1371 (mono_debug_add_method): Don't crash if we don't have line numbers.
1372 Initialize the newly added fields.
1374 * debug-stabs.c: Record first and last line, emit filename info at the
1375 beginning of the stab file, gdb ignores the types otherwise.
1377 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1378 emit line number info for the first and last line.
1380 2002-03-28 Dietmar Maurer <dietmar@ximian.com>
1382 * invoke.c (arch_create_delegate_trampoline): impl.
1384 Thu Mar 28 11:58:53 CET 2002 Paolo Molaro <lupus@ximian.com>

1389 * debug.h, debug.c: constify char* argument.
1391 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

1414 * debug-stabs.c (write_method_stabs): Don't generate method lines if
1415 we don't have line number information. Use `minfo->method_info.this_offset'
1416 instead of hardcoding 8.
1418 * debug.c (debug_generate_method_lines): Don't crash if we don't have
1419 line number information.

1444 2002-03-23 Martin Baulig <martin@gnome.org>
1446 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1447 to do it before the X86_CMP.
1448 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1449 (reg: CLT (lreg, lreg)): Likewise.
1450 (reg: CLT_UN (lreg, lreg)): Likewise.

1480 removed everything which is already in MonoDebugMethodInfo.
1482 * debug.c (debug_generate_method_lines): Generate the MonoILOffsetInfo array.

1521 * debug.c (mono_debug_get_type): Recursively call this for all function members
1523 (mono_debug_add_method): Don't mangle function names, this must be done by the
1524 debugger backend if the debugging format needs mangled names.
1526 * debug-dwarf2.c: Improved support for classes, added member functions.
1528 2002-03-16 Martin Baulig <martin@gnome.org>
1530 * debug.c (mono_debug_get_type): Recursively call this for all members and
1531 parent classes of a class type.
1533 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1534 since GDB doesn't like Java very much.
1536 2002-03-16 Martin Baulig <martin@gnome.org>
1538 * debug-dwarf2.c: Added support for enums.
1540 2002-03-15 Martin Baulig <martin@gnome.org>

1561 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1563 (mono_debug_open_file): Added MonoDebugFormat argument.
1564 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1565 this function from GDB. It's now safe to call this function multiple times;
1566 it'll always write a complete debugging file.
1568 * debug.c: Splitted this file into a general part which remains in this file
1569 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1570 All public functions now call a corresponding format specific function.
1572 * debug.c: The following changes are private to debug.c:
1573 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1574 (record_line_number, debug_generate_method_lines): New private functions.
1575 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1576 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1577 mono_debug_open_assembly_dwarf2).
1578 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1579 now safe to call this function multiple times.
1580 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1581 returns an unique index for this type. It's used to ensure that we only write
1582 each class once to the debugging file.
1583 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1584 data structure, but don't directly write to the debugging file. This is done
1585 later from mono_debug_write_assembly().
1587 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1588 debugging output. Call mono_debug_close() on cleanup if necessary.
1590 2002-03-14 Martin Baulig <martin@gnome.org>
1592 * debug-private.h: New private header file.
1594 * debug-stabs.c: Added the stabs type generation stuff which was
1595 previously in debug.c.
1597 * debug-dwarf.c: Started to implement type support. We're currently
1598 only writing this most basic types to the dwarf file, but this will
1601 2002-03-13 Martin Baulig <martin@gnome.org>
1603 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1604 debugging code. They're now in CVS, but not yet used anywhere.
1606 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1608 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1609 macros, included new delegate code from Daniel Stodden.
1612 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1614 * jit.c: verify that corlib and runtime are in sync.
1616 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1618 * emit-x86.c, jit.c: use the debug-helpers facilities to
1619 describe and match a method when debugging.
1621 2002-03-10 Martin Baulig <martin@gnome.org>
1623 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1624 output, put a nop instruction at the start of all functions so that
1625 the adresses won't change when using --debug.
1627 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1628 the bytecode area, stabs needs a line number in the .il file. Use the
1629 new info->moffsets to get the line number.
1630 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1631 `moffsets' is an array of `total_lines' fields (total number of lines
1632 in the .il file); for each line in the .il field, this array contains
1633 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1634 of a method and 0 otherwise.
1635 (debug_load_method_lines): Read the whole .il file and initialize the
1636 info->moffsets field.
1638 2002-03-09 Martin Baulig <martin@gnome.org>
1640 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1641 the unnecessary CDQ instruction.
1643 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1645 * jit.c (mono_analyze_stack): only load addresses of value types
1646 on the runtime stack.
1648 2002-03-07 Duncan Mak <duncan@ximian.com>
1650 * Makefile.am: A small patch fixing errors in vpath-based builds
1651 (make clean failing to rerun monoburg due to BUILT_SOURCES usage),

1712 (mono_compute_branches): patch real jump address (instead of
1713 emitting code twice)
1715 Tue Feb 26 11:56:03 CET 2002 Paolo Molaro <lupus@ximian.com>
1717 * x86.brg: optimize cmp reg,0 -> test reg.
1719 Sun Feb 24 13:58:34 CET 2002 Paolo Molaro <lupus@ximian.com>

2309 * x86.brg: branch addresses are now resolved
2311 * testjit.c (compute_branches): compute address of branches
2313 * x86.brg: emit real x86 instructions
2315 * testjit.c: call objdump to disassemble the output
2317 2001-09-13 Dietmar Maurer <dietmar@ximian.com>
2319 * x86.brg: use the right offsets to access local variables
2322 * emit-x86.c: only save/restore callee saved registers if they are
2325 * testjit.c (tree_allocate_regs): use the new MonoRegSet to
2327 (mono_compile_method): changed the tree for mothod calls
2334 2001-09-10 Miguel de Icaza <miguel@ximian.com>
2336 * x86.brg: Use Unix assembly syntax.
2338 * emit-x86.c: support code, should be moved
2340 * testjit.c: Use GPtrArrays instead of GLists, as those are very
2341 inefficient at appends.
2343 * Renamed `create_new_leave' to `create_new_leaf'
