1 2003-01-04 Martin Baulig <martin@ximian.com>
3 * debug.c (release_symbol_file_table): Only call this if we're
4 actually modifying the symbol tables.
5 (mono_debug_open): Always set the `mono_debugger_class_init_func'
6 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
8 2003-01-03 Martin Baulig <martin@ximian.com>
10 * debug.c: Disable the mono debugger stuff on Windows.
12 2003-01-03 Martin Baulig <martin@ximian.com>
14 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
15 function. This is called from the breakpoint trampoline to signal
16 the debugger and wait until it has reload the symbol tables.
18 * trampoline.c (get_breakpoint_trampoline): Call the new
19 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
20 trampoline just before the breakpoint.

25 field to point to the MonoGlobalSymbolTable.
27 2002-12-30 Martin Baulig <martin@ximian.com>
29 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
30 This variable now specifies that the symbol tables have been
31 modified after the last notification has been send. The debugger
32 uses this flag to check whether it needs to reload the symbol
34 (debugger_compile_method): Just send a notification to the
35 debugger, but don't set the modified flag. It may or may not be
36 set when the debugger gets the notification - depending on whether
37 the JIT compilation added a new method to the symbol tables.
39 2002-12-30 Martin Baulig <martin@ximian.com>
41 * debug.c (debugger_compile_method): This is a wrapper around
42 mono_compile_method() which always sends a notification to the
45 2002-12-30 Martin Baulig <martin@ximian.com>
47 * debug.c: Reload the symbol file table before sending the
48 notification event to the debugger.
49 (MonoDebuggerInfo): Removed `update_symbol_file_table'.

59 declaring ret at the top of the function.
61 2002-12-30 Martin Baulig <martin@ximian.com>
63 * debug.c: When running under the mono debugger, create a special
64 debugger thread; always protect the symbol tables with a mutex.
66 2002-12-28 Martin Baulig <martin@ximian.com>
68 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
69 incremented each time one of the symbol tables is modified.
71 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
73 * jit.c: fix LDELEMA implementation here as well.

104 native code using gcc generated exception tables (-fexception).
106 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
108 * exception.c: include some code from Zoltan Varga, but modified
111 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
113 * exception.c: massive code cleanups. The code is still
114 architecture dependent, but it should be now possible to reuse the
115 complex parts for other architecture.
117 2002-11-15 Dick Porter <dick@ximian.com>
119 * jit.c: Pass the attach callback to mono_runtime_init().

167 name of the managed file we're executing
169 2002-09-26 Martin Baulig <martin@gnome.org>
171 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
172 trampoline into the vtable, also use it for non-virtual methods,
173 remove the breakpoint when done.
175 2002-09-26 Martin Baulig <martin@gnome.org>
177 * debug.c (debug_load_method_lines): Block SIGCHLD while running
180 2002-09-26 Martin Baulig <martin@gnome.org>
182 * debug.c: Reworked the whole debugging stuff. We have now one
183 single `mono_debug_handle' which keeps a hashtable of
184 `AssemblyDebugInfo's (which may have different debugging formats).
185 The AssemblyDebugInfo is now created when the assembly is loaded,
186 but never when adding a class/type.
188 * mono.c: Initialize debugging stuff after corlib and the assembly
191 2002-09-25 Martin Baulig <martin@gnome.org>
193 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
194 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
196 (DebugMethodInfo): Removed `line_numbers'.
198 * debug.c: Reworked the line number generation; we're now using
199 the MonoDebugLineNumberEntry try for all debugging formats. This
200 type also includes the line number and IL offset, this allows the
201 JIT to produce better line number info: we only emit line number
202 information for source lines which actually have code.
204 2002-09-25 Martin Baulig <martin@gnome.org>
206 * debug.h: Removed external declaration of all functions which
207 should only be called from the Mono Debugger and also made them
208 static. Since the debugger gets their address from the
209 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
212 2002-09-25 Martin Baulig <martin@gnome.org>
214 Improved breakpoint support, we can now dynamically insert and
215 remove breakpoints at runtime and when called from withing the
216 Mono Debugger, we're using a special breakpoint trampoline.

219 whether to insert a breakpoint for a method.
220 (mono_insert_breakpoint): New method to insert a breakpoint.
221 (mono_insert_breakpoint_full): New method to insert a breakpoint,
222 takes a MonoMethodDesc.
223 (mono_remove_breakpoint): New method to remove a breakpoint.
225 * debug.c (mono_debugger_insert_breakpoint): New function for the
226 debugger. Should only be called from the debugger.
227 (mono_debugger_remove_breakpoint): Likewise.
229 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
231 * trampoline.c (get_breakpoint_trampoline): New static function to
232 create a special breakpoint trampoline for the debugger.
233 (x86_magic_trampoline): If we're running inside the Mono Debugger
234 and a breakpoint was requested for the method, generate a special
235 breakpoint trampoline.
237 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
238 to insert a breakpoint.
239 (mono_debug_last_breakpoint_address): Removed.
240 (match_debug_method): Removed, use mono_method_has_breakpoint().
242 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
244 * jit.c: reorder mono_runtime_cleanup () call since it needs the
245 engine still fully working.
247 2002-09-24 Martin Baulig <martin@gnome.org>
249 * debug.c (mono_debug_open): When we're invoked from inside the
250 Mono Debugger, set mono_debugger_class_init_func (exported in
251 metadata/class.c) to mono_add_type().
252 (mono_add_type): Call mono_debug_symfile_add_type().
254 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
256 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
257 Run finalize on domain cleanup.
258 * mono.c: call setlocale ().
259 * trampoline.c: clearer error message for invalid trampoline.
261 2002-09-21 Martin Baulig <martin@gnome.org>
263 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
264 instead of writing a byte blob.
265 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
266 (mono_debug_add_method): Incrementally add the new method to the symbol
269 * exception.c (arch_handle_exception): If we have debugging support,
270 call mono_debugger_update_symbol_file_table () as well.
272 2002-09-20 Martin Baulig <martin@gnome.org>
274 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
275 the size of the variable.
277 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
279 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
280 iterations if we visit blocks in reverse order.
282 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
284 * jit.c (mono_analyze_stack): cleaup of the array code
286 * exception.c: added patch from Julio Merno to fix bug #30048

294 2002-09-06 Martin Baulig <martin@gnome.org>
296 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
297 If you were getting random crashes when using the JIT with debugging
298 turned on, this fixes it.
300 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
302 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
304 2002-09-05 Martin Baulig <martin@gnome.org>
306 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
307 which is read by the debugger.
309 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>

323 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
324 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
325 `mono_symfile' to `symfile'.
327 * debug.c (mono_debug_open): Replaced the assembly argument with a
328 file name argument; you can now call this before loading the assembly.
329 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
330 we now use MonoSymbolFileLineNumberEntry's and a separate address array
331 instead; splitted out all MonoSymbolFileLineNumberEntry code into
332 debug_generate_il_offsets() and debug_update_il_offsets().
333 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
334 created when reading the symbol file or from debug_load_method_lines().
335 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
337 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before

361 * mono.c: don't use the cil-coff header outside of the loader.
363 2002-08-27 Martin Baulig <martin@gnome.org>
365 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
366 to use global variables for this since they're stored in a core file.

375 (arch_create_jit_trampoline): Use the new global variable to store the
376 generic trampoline code instead of using a static one. This allows the
377 debugger to access this variable to check whether a method is a trampoline.
379 * debug.h (mono_generic_trampoline_code): Added external declaration.
381 2002-08-27 Martin Baulig <martin@gnome.org>
383 * debug.c (MonoDebugHandle): Moved the method hash into the
384 AssemblyDebugInfo struct since we need to use a separate hash for each
387 * debug.c: Added special undocumented command line argument to create a
388 symbol file for IL files on-the-fly. In this case, we also need to create
389 the IL files and parse them.

461 2002-08-08 Dietmar Maurer <dietmar@ximian.com>
463 * exception.c (arch_handle_exception): simply return and let the
464 libpthread/kernel restore the context. This should work on recent
465 versions of linuxthreads.
467 * jit.c (mono_runtime_install_handlers): switch back to use
468 sigaction from libpthreads. As long as this does not make problems
469 we should use this instead of syscall.

488 2002-07-30 Sergey Chaban <serge@wildwestsoftware.com>
490 * x86.brg (LOCALLOC): under Windows, if allocation size is bigger
491 than one page, it's necessary to allocate memory incrementally,
492 in page-size steps, performing stack-touch every time.
493 Also added LOCALLOC(CONST_I4) implementation.
495 2002-07-27 Dietmar Maurer <dietmar@ximian.com>
497 * jit.c (mono_get_runtime_method): code cleanup

911 2002-05-21 Martin Baulig <martin@gnome.org>
913 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
914 file for all assemblies. Currently, the JIT doesn't put all methods
915 from a single assembly into a continuous region of memory. We were

1015 * exception.c (arch_handle_exception): EIP now points to the call
1016 instruction, not to the instruction after the call. This fixes the

1387 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1388 numbers, we still need to generate the IL offsets here. Emit line numbers
1389 for `prologue_end_offset' (the first line of actual code) and
1390 `epilogue_begin_offset' (the line of the method's closing brace).
1391 Don't crash if cfg->bblocks [i].forest is NULL.
1392 (mono_debug_add_method): Don't crash if we don't have line numbers.
1393 Initialize the newly added fields.
1395 * debug-stabs.c: Record first and last line, emit filename info at the

1398 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1399 emit line number info for the first and last line.
1401 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

1435 * debug-stabs.c (write_method_stabs): Don't generate method lines if
1436 we don't have line number information. Use `minfo->method_info.this_offset'
1437 instead of hardcoding 8.

1465 2002-03-23 Martin Baulig <martin@gnome.org>
1467 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1468 to do it before the X86_CMP.
1469 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1470 (reg: CLT (lreg, lreg)): Likewise.
1471 (reg: CLT_UN (lreg, lreg)): Likewise.

1501 removed everything which is already in MonoDebugMethodInfo.
1503 * debug.c (debug_generate_method_lines): Generate the MonoILOffsetInfo array.

1542 * debug.c (mono_debug_get_type): Recursively call this for all function members
1544 (mono_debug_add_method): Don't mangle function names, this must be done by the
1545 debugger backend if the debugging format needs mangled names.
1547 * debug-dwarf2.c: Improved support for classes, added member functions.
1549 2002-03-16 Martin Baulig <martin@gnome.org>
1551 * debug.c (mono_debug_get_type): Recursively call this for all members and
1552 parent classes of a class type.
1554 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1555 since GDB doesn't like Java very much.
1557 2002-03-16 Martin Baulig <martin@gnome.org>
1559 * debug-dwarf2.c: Added support for enums.
1561 2002-03-15 Martin Baulig <martin@gnome.org>

1582 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1584 (mono_debug_open_file): Added MonoDebugFormat argument.
1585 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1586 this function from GDB. It's now safe to call this function multiple times;
1587 it'll always write a complete debugging file.
1589 * debug.c: Splitted this file into a general part which remains in this file
1590 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1591 All public functions now call a corresponding format specific function.
1593 * debug.c: The following changes are private to debug.c:
1594 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1595 (record_line_number, debug_generate_method_lines): New private functions.
1596 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1597 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1598 mono_debug_open_assembly_dwarf2).
1599 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1600 now safe to call this function multiple times.
1601 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1602 returns an unique index for this type. It's used to ensure that we only write
1603 each class once to the debugging file.
1604 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1605 data structure, but don't directly write to the debugging file. This is done
1606 later from mono_debug_write_assembly().
1608 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1609 debugging output. Call mono_debug_close() on cleanup if necessary.
1611 2002-03-14 Martin Baulig <martin@gnome.org>
1613 * debug-private.h: New private header file.
1615 * debug-stabs.c: Added the stabs type generation stuff which was
1616 previously in debug.c.
1618 * debug-dwarf.c: Started to implement type support. We're currently
1619 only writing this most basic types to the dwarf file, but this will
1622 2002-03-13 Martin Baulig <martin@gnome.org>
1624 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1625 debugging code. They're now in CVS, but not yet used anywhere.
1627 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1629 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1630 macros, included new delegate code from Daniel Stodden.
1633 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1635 * jit.c: verify that corlib and runtime are in sync.
1637 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1639 * emit-x86.c, jit.c: use the debug-helpers facilities to
1640 describe and match a method when debugging.
1642 2002-03-10 Martin Baulig <martin@gnome.org>
1644 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1645 output, put a nop instruction at the start of all functions so that
1646 the adresses won't change when using --debug.
1648 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1649 the bytecode area, stabs needs a line number in the .il file. Use the
1650 new info->moffsets to get the line number.
1651 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1652 `moffsets' is an array of `total_lines' fields (total number of lines
1653 in the .il file); for each line in the .il field, this array contains
1654 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1655 of a method and 0 otherwise.
1656 (debug_load_method_lines): Read the whole .il file and initialize the
1657 info->moffsets field.
1659 2002-03-09 Martin Baulig <martin@gnome.org>
1661 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1662 the unnecessary CDQ instruction.
1664 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1666 * jit.c (mono_analyze_stack): only load addresses of value types
1667 on the runtime stack.
1669 2002-03-07 Duncan Mak <duncan@ximian.com>
1671 * Makefile.am: A small patch fixing errors in vpath-based builds
1672 (make clean failing to rerun monoburg due to BUILT_SOURCES usage),
1673 committed for Daniel Stodden <stodden@in.tum.de>.

1712 2002-02-28 Dietmar Maurer <dietmar@ximian.com>
1714 * emit-x86.c (arch_create_jit_trampoline): save/restore LMF before
1715 calling into unmanaged code (arch_compile_method).
1717 * x86.brg: impl. CONV_I4 (freg) with correct rounding

2302 Tue Sep 18 13:19:16 CEST 2001 Paolo Molaro <lupus@ximian.com>
2304 * testjit.c: better/faster align code. Handle ldloc.s and stloc.s.
2306 2001-09-17 Miguel de Icaza <miguel@ximian.com>
2308 * testjit.c (mono_compile_method): Provide better error reporting.
2310 2001-09-17 Dietmar Maurer <dietmar@ximian.com>
2312 * testjit.c (tree_get_address): impl. to fix address bug
2313 (tree_get_address): make sure that we can only jump to the first
2314 instruction of a tree.
2316 * x86.brg: emit real code for calls
2318 * testjit.c (create_jit_trampoline): creates a function to trigger jit
2320 (mono_compile_method): reversed argument order
2322 2001-09-15 Dietmar Maurer <dietmar@ximian.com>
2324 * x86.brg (stmt): don't emit unnecessary register moves
2326 * testjit.c (tree_allocate_regs): free registers earlier
2328 2001-09-14 Dietmar Maurer <dietmar@ximian.com>
2330 * x86.brg: branch addresses are now resolved
2332 * testjit.c (compute_branches): compute address of branches
2334 * x86.brg: emit real x86 instructions
2336 * testjit.c: call objdump to disassemble the output
2338 2001-09-13 Dietmar Maurer <dietmar@ximian.com>
2340 * x86.brg: use the right offsets to access local variables
2343 * emit-x86.c: only save/restore callee saved registers if they are
2346 * testjit.c (tree_allocate_regs): use the new MonoRegSet to
2348 (mono_compile_method): changed the tree for mothod calls
2355 2001-09-10 Miguel de Icaza <miguel@ximian.com>
2357 * x86.brg: Use Unix assembly syntax.
2359 * emit-x86.c: support code, should be moved
2361 * testjit.c: Use GPtrArrays instead of GLists, as those are very
2362 inefficient at appends.
2364 * Renamed `create_new_leave' to `create_new_leaf'
