3 * debug.c: Disable the mono debugger stuff on Windows.
5 2003-01-03 Martin Baulig <martin@ximian.com>
7 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
8 function. This is called from the breakpoint trampoline to signal
9 the debugger and wait until it has reload the symbol tables.
11 * trampoline.c (get_breakpoint_trampoline): Call the new
12 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
13 trampoline just before the breakpoint.
15 2002-12-31 Martin Baulig <martin@ximian.com>
17 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
18 field to point to the MonoGlobalSymbolTable.
20 2002-12-30 Martin Baulig <martin@ximian.com>
22 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
23 This variable now specifies that the symbol tables have been
24 modified after the last notification has been send. The debugger
25 uses this flag to check whether it needs to reload the symbol
27 (debugger_compile_method): Just send a notification to the
28 debugger, but don't set the modified flag. It may or may not be
29 set when the debugger gets the notification - depending on whether
30 the JIT compilation added a new method to the symbol tables.
32 2002-12-30 Martin Baulig <martin@ximian.com>
34 * debug.c (debugger_compile_method): This is a wrapper around
35 mono_compile_method() which always sends a notification to the
38 2002-12-30 Martin Baulig <martin@ximian.com>
40 * debug.c: Reload the symbol file table before sending the
41 notification event to the debugger.
42 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
44 2002-12-31 Martin Baulig <martin@ximian.com>

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

89 * x86.brg (stmt): POP floating point stack correctly
91 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
93 * emit-x86.c (arch_emit_prologue): don't save caller saved
96 * exception.c (x86_unwind_native_frame): support exceptions inside
97 native code using gcc generated exception tables (-fexception).
99 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
101 * exception.c: include some code from Zoltan Varga, but modified
104 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
106 * exception.c: massive code cleanups. The code is still
107 architecture dependent, but it should be now possible to reuse the
108 complex parts for other architecture.
110 2002-11-15 Dick Porter <dick@ximian.com>
112 * jit.c: Pass the attach callback to mono_runtime_init().

160 name of the managed file we're executing
162 2002-09-26 Martin Baulig <martin@gnome.org>
164 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
165 trampoline into the vtable, also use it for non-virtual methods,
166 remove the breakpoint when done.
168 2002-09-26 Martin Baulig <martin@gnome.org>
170 * debug.c (debug_load_method_lines): Block SIGCHLD while running
173 2002-09-26 Martin Baulig <martin@gnome.org>
175 * debug.c: Reworked the whole debugging stuff. We have now one
176 single `mono_debug_handle' which keeps a hashtable of
177 `AssemblyDebugInfo's (which may have different debugging formats).
178 The AssemblyDebugInfo is now created when the assembly is loaded,
179 but never when adding a class/type.
181 * mono.c: Initialize debugging stuff after corlib and the assembly
184 2002-09-25 Martin Baulig <martin@gnome.org>
186 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
187 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
189 (DebugMethodInfo): Removed `line_numbers'.
191 * debug.c: Reworked the line number generation; we're now using
192 the MonoDebugLineNumberEntry try for all debugging formats. This
193 type also includes the line number and IL offset, this allows the
194 JIT to produce better line number info: we only emit line number
195 information for source lines which actually have code.
197 2002-09-25 Martin Baulig <martin@gnome.org>
199 * debug.h: Removed external declaration of all functions which
200 should only be called from the Mono Debugger and also made them
201 static. Since the debugger gets their address from the
202 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
205 2002-09-25 Martin Baulig <martin@gnome.org>
207 Improved breakpoint support, we can now dynamically insert and
208 remove breakpoints at runtime and when called from withing the
209 Mono Debugger, we're using a special breakpoint trampoline.
211 * debug.h (mono_method_has_breakpoint): New method to check
212 whether to insert a breakpoint for a method.
213 (mono_insert_breakpoint): New method to insert a breakpoint.
214 (mono_insert_breakpoint_full): New method to insert a breakpoint,
215 takes a MonoMethodDesc.
216 (mono_remove_breakpoint): New method to remove a breakpoint.
218 * debug.c (mono_debugger_insert_breakpoint): New function for the
219 debugger. Should only be called from the debugger.
220 (mono_debugger_remove_breakpoint): Likewise.
222 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
224 * trampoline.c (get_breakpoint_trampoline): New static function to
225 create a special breakpoint trampoline for the debugger.
226 (x86_magic_trampoline): If we're running inside the Mono Debugger
227 and a breakpoint was requested for the method, generate a special
228 breakpoint trampoline.
230 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
231 to insert a breakpoint.
232 (mono_debug_last_breakpoint_address): Removed.
233 (match_debug_method): Removed, use mono_method_has_breakpoint().
235 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
237 * jit.c: reorder mono_runtime_cleanup () call since it needs the
238 engine still fully working.
240 2002-09-24 Martin Baulig <martin@gnome.org>
242 * debug.c (mono_debug_open): When we're invoked from inside the
243 Mono Debugger, set mono_debugger_class_init_func (exported in
244 metadata/class.c) to mono_add_type().
245 (mono_add_type): Call mono_debug_symfile_add_type().
247 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
249 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
250 Run finalize on domain cleanup.
251 * mono.c: call setlocale ().
252 * trampoline.c: clearer error message for invalid trampoline.
254 2002-09-21 Martin Baulig <martin@gnome.org>
256 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
257 instead of writing a byte blob.
258 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
259 (mono_debug_add_method): Incrementally add the new method to the symbol
262 * exception.c (arch_handle_exception): If we have debugging support,
263 call mono_debugger_update_symbol_file_table () as well.
265 2002-09-20 Martin Baulig <martin@gnome.org>
267 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
268 the size of the variable.
270 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
272 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
273 iterations if we visit blocks in reverse order.
275 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
277 * jit.c (mono_analyze_stack): cleaup of the array code
279 * exception.c: added patch from Julio Merno to fix bug #30048

283 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
285 * x86.brg (LDELEMA): use x86_lea
287 2002-09-06 Martin Baulig <martin@gnome.org>
289 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
290 If you were getting random crashes when using the JIT with debugging
291 turned on, this fixes it.
293 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
295 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
297 2002-09-05 Martin Baulig <martin@gnome.org>
299 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
300 which is read by the debugger.
302 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>

314 * debug-dwarf2-plus.c: Removed.
316 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
317 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
318 `mono_symfile' to `symfile'.
320 * debug.c (mono_debug_open): Replaced the assembly argument with a
321 file name argument; you can now call this before loading the assembly.
322 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
323 we now use MonoSymbolFileLineNumberEntry's and a separate address array
324 instead; splitted out all MonoSymbolFileLineNumberEntry code into
325 debug_generate_il_offsets() and debug_update_il_offsets().
326 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
327 created when reading the symbol file or from debug_load_method_lines().
328 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
330 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before

349 * debug.c: The mono symbol file is installed together with the assembly
350 it belongs to and it's used on a per-image basis.
352 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
354 * mono.c: don't use the cil-coff header outside of the loader.
356 2002-08-27 Martin Baulig <martin@gnome.org>
358 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
359 to use global variables for this since they're stored in a core file.

367 * trampoline.c (mono_generic_trampoline_code): New global variable.
368 (arch_create_jit_trampoline): Use the new global variable to store the
369 generic trampoline code instead of using a static one. This allows the
370 debugger to access this variable to check whether a method is a trampoline.
372 * debug.h (mono_generic_trampoline_code): Added external declaration.
374 2002-08-27 Martin Baulig <martin@gnome.org>
376 * debug.c (MonoDebugHandle): Moved the method hash into the
377 AssemblyDebugInfo struct since we need to use a separate hash for each
380 * debug.c: Added special undocumented command line argument to create a
381 symbol file for IL files on-the-fly. In this case, we also need to create
382 the IL files and parse them.

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

429 of the intermediate result that was causing troubles.
431 2002-08-16 Nick Drochak <ndrochak@gol.com>
433 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers

454 2002-08-08 Dietmar Maurer <dietmar@ximian.com>
456 * exception.c (arch_handle_exception): simply return and let the
457 libpthread/kernel restore the context. This should work on recent
458 versions of linuxthreads.
460 * jit.c (mono_runtime_install_handlers): switch back to use
461 sigaction from libpthreads. As long as this does not make problems
462 we should use this instead of syscall.

481 2002-07-30 Sergey Chaban <serge@wildwestsoftware.com>
483 * x86.brg (LOCALLOC): under Windows, if allocation size is bigger
484 than one page, it's necessary to allocate memory incrementally,
485 in page-size steps, performing stack-touch every time.
486 Also added LOCALLOC(CONST_I4) implementation.
488 2002-07-27 Dietmar Maurer <dietmar@ximian.com>
490 * jit.c (mono_get_runtime_method): code cleanup

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

1008 * exception.c (arch_handle_exception): EIP now points to the call
1009 instruction, not to the instruction after the call. This fixes the

1380 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1381 numbers, we still need to generate the IL offsets here. Emit line numbers
1382 for `prologue_end_offset' (the first line of actual code) and
1383 `epilogue_begin_offset' (the line of the method's closing brace).
1384 Don't crash if cfg->bblocks [i].forest is NULL.
1385 (mono_debug_add_method): Don't crash if we don't have line numbers.
1386 Initialize the newly added fields.
1388 * debug-stabs.c: Record first and last line, emit filename info at the

1391 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1392 emit line number info for the first and last line.
1394 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

1428 * debug-stabs.c (write_method_stabs): Don't generate method lines if
1429 we don't have line number information. Use `minfo->method_info.this_offset'
1430 instead of hardcoding 8.

1458 2002-03-23 Martin Baulig <martin@gnome.org>
1460 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1461 to do it before the X86_CMP.
1462 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1463 (reg: CLT (lreg, lreg)): Likewise.

1542 2002-03-16 Martin Baulig <martin@gnome.org>
1544 * debug.c (mono_debug_get_type): Recursively call this for all members and
1545 parent classes of a class type.
1547 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1548 since GDB doesn't like Java very much.
1550 2002-03-16 Martin Baulig <martin@gnome.org>
1552 * debug-dwarf2.c: Added support for enums.
1554 2002-03-15 Martin Baulig <martin@gnome.org>

1575 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1577 (mono_debug_open_file): Added MonoDebugFormat argument.
1578 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1579 this function from GDB. It's now safe to call this function multiple times;
1580 it'll always write a complete debugging file.
1582 * debug.c: Splitted this file into a general part which remains in this file
1583 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1584 All public functions now call a corresponding format specific function.
1586 * debug.c: The following changes are private to debug.c:
1587 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1588 (record_line_number, debug_generate_method_lines): New private functions.
1589 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1590 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1591 mono_debug_open_assembly_dwarf2).
1592 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1593 now safe to call this function multiple times.
1594 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1595 returns an unique index for this type. It's used to ensure that we only write
1596 each class once to the debugging file.
1597 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1598 data structure, but don't directly write to the debugging file. This is done
1599 later from mono_debug_write_assembly().
1601 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1602 debugging output. Call mono_debug_close() on cleanup if necessary.
1604 2002-03-14 Martin Baulig <martin@gnome.org>
1606 * debug-private.h: New private header file.
1608 * debug-stabs.c: Added the stabs type generation stuff which was
1609 previously in debug.c.
1611 * debug-dwarf.c: Started to implement type support. We're currently
1612 only writing this most basic types to the dwarf file, but this will
1615 2002-03-13 Martin Baulig <martin@gnome.org>
1617 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1618 debugging code. They're now in CVS, but not yet used anywhere.
1620 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1622 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1623 macros, included new delegate code from Daniel Stodden.
1626 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1628 * jit.c: verify that corlib and runtime are in sync.
1630 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1632 * emit-x86.c, jit.c: use the debug-helpers facilities to
1633 describe and match a method when debugging.
1635 2002-03-10 Martin Baulig <martin@gnome.org>
1637 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1638 output, put a nop instruction at the start of all functions so that
1639 the adresses won't change when using --debug.
1641 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1642 the bytecode area, stabs needs a line number in the .il file. Use the
1643 new info->moffsets to get the line number.
1644 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1645 `moffsets' is an array of `total_lines' fields (total number of lines
1646 in the .il file); for each line in the .il field, this array contains
1647 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1648 of a method and 0 otherwise.
1649 (debug_load_method_lines): Read the whole .il file and initialize the
1650 info->moffsets field.
1652 2002-03-09 Martin Baulig <martin@gnome.org>
1654 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1655 the unnecessary CDQ instruction.
1657 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1659 * jit.c (mono_analyze_stack): only load addresses of value types
1660 on the runtime stack.
1662 2002-03-07 Duncan Mak <duncan@ximian.com>
1664 * Makefile.am: A small patch fixing errors in vpath-based builds
1665 (make clean failing to rerun monoburg due to BUILT_SOURCES usage),
1666 committed for Daniel Stodden <stodden@in.tum.de>.

2303 2001-09-17 Dietmar Maurer <dietmar@ximian.com>
2305 * testjit.c (tree_get_address): impl. to fix address bug
2306 (tree_get_address): make sure that we can only jump to the first
2307 instruction of a tree.
2309 * x86.brg: emit real code for calls
2311 * testjit.c (create_jit_trampoline): creates a function to trigger jit
2313 (mono_compile_method): reversed argument order
2315 2001-09-15 Dietmar Maurer <dietmar@ximian.com>
2317 * x86.brg (stmt): don't emit unnecessary register moves
2319 * testjit.c (tree_allocate_regs): free registers earlier
2321 2001-09-14 Dietmar Maurer <dietmar@ximian.com>
2323 * x86.brg: branch addresses are now resolved
2325 * testjit.c (compute_branches): compute address of branches
2327 * x86.brg: emit real x86 instructions
2329 * testjit.c: call objdump to disassemble the output
2331 2001-09-13 Dietmar Maurer <dietmar@ximian.com>
2333 * x86.brg: use the right offsets to access local variables
2336 * emit-x86.c: only save/restore callee saved registers if they are
2339 * testjit.c (tree_allocate_regs): use the new MonoRegSet to
2341 (mono_compile_method): changed the tree for mothod calls
2348 2001-09-10 Miguel de Icaza <miguel@ximian.com>
2350 * x86.brg: Use Unix assembly syntax.
2352 * emit-x86.c: support code, should be moved
2354 * testjit.c: Use GPtrArrays instead of GLists, as those are very
2355 inefficient at appends.
2357 * Renamed `create_new_leave' to `create_new_leaf'
