1 2003-01-05 Martin Baulig <martin@ximian.com>
3 * debug.h (MonoDebugFormat): Added
4 `MONO_DEBUG_FORMAT_MONO_DEBUGGER'; this allows us to check whether
5 we're running inside the Mono Debugger prior to the args parsing.
7 2003-01-04 Martin Baulig <martin@ximian.com>
9 * debug.c (release_symbol_file_table): Only call this if we're
10 actually modifying the symbol tables.
11 (mono_debug_open): Always set the `mono_debugger_class_init_func'
12 for MONO_DEBUG_FORMAT_MONO; this stuff should also go into core dumps.
14 2003-01-03 Martin Baulig <martin@ximian.com>
16 * debug.c: Disable the mono debugger stuff on Windows.
18 2003-01-03 Martin Baulig <martin@ximian.com>
20 * debug.c (mono_debugger_trampoline_breakpoint_callback): New
21 function. This is called from the breakpoint trampoline to signal
22 the debugger and wait until it has reload the symbol tables.
24 * trampoline.c (get_breakpoint_trampoline): Call the new
25 mono_debugger_trampoline_breakpoint_callback() in the breakpoint
26 trampoline just before the breakpoint.
28 2002-12-31 Martin Baulig <martin@ximian.com>
30 * debug.c (MonoDebuggerSymbolFileTable): Added `global_symfile'
31 field to point to the MonoGlobalSymbolTable.
33 2002-12-30 Martin Baulig <martin@ximian.com>
35 * debug.c (MonoDebuggerInfo): Put back `symbol_file_modified'.
36 This variable now specifies that the symbol tables have been
37 modified after the last notification has been send. The debugger
38 uses this flag to check whether it needs to reload the symbol
40 (debugger_compile_method): Just send a notification to the
41 debugger, but don't set the modified flag. It may or may not be
42 set when the debugger gets the notification - depending on whether
43 the JIT compilation added a new method to the symbol tables.
45 2002-12-30 Martin Baulig <martin@ximian.com>
47 * debug.c (debugger_compile_method): This is a wrapper around
48 mono_compile_method() which always sends a notification to the
51 2002-12-30 Martin Baulig <martin@ximian.com>
53 * debug.c: Reload the symbol file table before sending the
54 notification event to the debugger.
55 (MonoDebuggerInfo): Removed `update_symbol_file_table'.
57 2002-12-31 Martin Baulig <martin@ximian.com>
59 * debug.c: Propertly lock everything and avoid race conditions.
60 (MonoDebuggerInfo): Removed the `symbol_file_modified' again.

65 declaring ret at the top of the function.
67 2002-12-30 Martin Baulig <martin@ximian.com>
69 * debug.c: When running under the mono debugger, create a special
70 debugger thread; always protect the symbol tables with a mutex.
72 2002-12-28 Martin Baulig <martin@ximian.com>
74 * debug.c (MonoDebuggerInfo): Added `symbol_file_modified'; it's
75 incremented each time one of the symbol tables is modified.
77 Thu Dec 19 18:31:54 CET 2002 Paolo Molaro <lupus@ximian.com>
79 * jit.c: fix LDELEMA implementation here as well.

100 * jit.c (mono_analyze_stack): added some additinal checks to verify IL code
102 * x86.brg (stmt): POP floating point stack correctly
104 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
106 * emit-x86.c (arch_emit_prologue): don't save caller saved
109 * exception.c (x86_unwind_native_frame): support exceptions inside
110 native code using gcc generated exception tables (-fexception).
112 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
114 * exception.c: include some code from Zoltan Varga, but modified
117 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
119 * exception.c: massive code cleanups. The code is still
120 architecture dependent, but it should be now possible to reuse the
121 complex parts for other architecture.
123 2002-11-15 Dick Porter <dick@ximian.com>
125 * jit.c: Pass the attach callback to mono_runtime_init().

170 2002-09-27 Dick Porter <dick@ximian.com>
172 * mono.c: Tell glib what the program name is, by passing it the
173 name of the managed file we're executing
175 2002-09-26 Martin Baulig <martin@gnome.org>
177 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
178 trampoline into the vtable, also use it for non-virtual methods,
179 remove the breakpoint when done.
181 2002-09-26 Martin Baulig <martin@gnome.org>
183 * debug.c (debug_load_method_lines): Block SIGCHLD while running
186 2002-09-26 Martin Baulig <martin@gnome.org>
188 * debug.c: Reworked the whole debugging stuff. We have now one
189 single `mono_debug_handle' which keeps a hashtable of
190 `AssemblyDebugInfo's (which may have different debugging formats).
191 The AssemblyDebugInfo is now created when the assembly is loaded,
192 but never when adding a class/type.
194 * mono.c: Initialize debugging stuff after corlib and the assembly
197 2002-09-25 Martin Baulig <martin@gnome.org>
199 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
200 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
202 (DebugMethodInfo): Removed `line_numbers'.
204 * debug.c: Reworked the line number generation; we're now using
205 the MonoDebugLineNumberEntry try for all debugging formats. This
206 type also includes the line number and IL offset, this allows the
207 JIT to produce better line number info: we only emit line number
208 information for source lines which actually have code.
210 2002-09-25 Martin Baulig <martin@gnome.org>
212 * debug.h: Removed external declaration of all functions which
213 should only be called from the Mono Debugger and also made them
214 static. Since the debugger gets their address from the
215 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
218 2002-09-25 Martin Baulig <martin@gnome.org>
220 Improved breakpoint support, we can now dynamically insert and
221 remove breakpoints at runtime and when called from withing the
222 Mono Debugger, we're using a special breakpoint trampoline.
224 * debug.h (mono_method_has_breakpoint): New method to check
225 whether to insert a breakpoint for a method.
226 (mono_insert_breakpoint): New method to insert a breakpoint.
227 (mono_insert_breakpoint_full): New method to insert a breakpoint,
228 takes a MonoMethodDesc.
229 (mono_remove_breakpoint): New method to remove a breakpoint.
231 * debug.c (mono_debugger_insert_breakpoint): New function for the
232 debugger. Should only be called from the debugger.
233 (mono_debugger_remove_breakpoint): Likewise.
235 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
237 * trampoline.c (get_breakpoint_trampoline): New static function to
238 create a special breakpoint trampoline for the debugger.
239 (x86_magic_trampoline): If we're running inside the Mono Debugger
240 and a breakpoint was requested for the method, generate a special
241 breakpoint trampoline.
243 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
244 to insert a breakpoint.
245 (mono_debug_last_breakpoint_address): Removed.
246 (match_debug_method): Removed, use mono_method_has_breakpoint().
248 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
250 * jit.c: reorder mono_runtime_cleanup () call since it needs the
251 engine still fully working.
253 2002-09-24 Martin Baulig <martin@gnome.org>
255 * debug.c (mono_debug_open): When we're invoked from inside the
256 Mono Debugger, set mono_debugger_class_init_func (exported in
257 metadata/class.c) to mono_add_type().
258 (mono_add_type): Call mono_debug_symfile_add_type().
260 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
262 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
263 Run finalize on domain cleanup.
264 * mono.c: call setlocale ().
265 * trampoline.c: clearer error message for invalid trampoline.
267 2002-09-21 Martin Baulig <martin@gnome.org>
269 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
270 instead of writing a byte blob.
271 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
272 (mono_debug_add_method): Incrementally add the new method to the symbol
275 * exception.c (arch_handle_exception): If we have debugging support,
276 call mono_debugger_update_symbol_file_table () as well.
278 2002-09-20 Martin Baulig <martin@gnome.org>
280 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
281 the size of the variable.
283 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
285 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
286 iterations if we visit blocks in reverse order.
288 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
290 * jit.c (mono_analyze_stack): cleaup of the array code
292 * exception.c: added patch from Julio Merno to fix bug #30048

296 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
298 * x86.brg (LDELEMA): use x86_lea
300 2002-09-06 Martin Baulig <martin@gnome.org>
302 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
303 If you were getting random crashes when using the JIT with debugging
304 turned on, this fixes it.
306 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
308 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
310 2002-09-05 Martin Baulig <martin@gnome.org>
312 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
313 which is read by the debugger.
315 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>

327 * debug-dwarf2-plus.c: Removed.
329 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
330 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
331 `mono_symfile' to `symfile'.
333 * debug.c (mono_debug_open): Replaced the assembly argument with a
334 file name argument; you can now call this before loading the assembly.
335 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
336 we now use MonoSymbolFileLineNumberEntry's and a separate address array
337 instead; splitted out all MonoSymbolFileLineNumberEntry code into
338 debug_generate_il_offsets() and debug_update_il_offsets().
339 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
340 created when reading the symbol file or from debug_load_method_lines().
341 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
343 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before

362 * debug.c: The mono symbol file is installed together with the assembly
363 it belongs to and it's used on a per-image basis.
365 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
367 * mono.c: don't use the cil-coff header outside of the loader.
369 2002-08-27 Martin Baulig <martin@gnome.org>
371 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
372 to use global variables for this since they're stored in a core file.

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

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

440 * x86.brg (mono_llmult_ovf): Simplified the code greatly by refactoring
441 the algebraic form we are using. This also eliminated a silly overflow
442 of the intermediate result that was causing troubles.
444 2002-08-16 Nick Drochak <ndrochak@gol.com>
446 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers

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

479 * jit.c: removed the createdelegate icall
480 (mono_analyze_stack): special case Array::Address()

494 2002-07-30 Sergey Chaban <serge@wildwestsoftware.com>
496 * x86.brg (LOCALLOC): under Windows, if allocation size is bigger
497 than one page, it's necessary to allocate memory incrementally,
498 in page-size steps, performing stack-touch every time.
499 Also added LOCALLOC(CONST_I4) implementation.
501 2002-07-27 Dietmar Maurer <dietmar@ximian.com>
503 * jit.c (mono_get_runtime_method): code cleanup

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

1393 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1394 numbers, we still need to generate the IL offsets here. Emit line numbers
1395 for `prologue_end_offset' (the first line of actual code) and
1396 `epilogue_begin_offset' (the line of the method's closing brace).
1397 Don't crash if cfg->bblocks [i].forest is NULL.
1398 (mono_debug_add_method): Don't crash if we don't have line numbers.
1399 Initialize the newly added fields.
1401 * debug-stabs.c: Record first and last line, emit filename info at the

1404 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1405 emit line number info for the first and last line.
1407 2002-03-28 Dietmar Maurer <dietmar@ximian.com>
1409 * invoke.c (arch_create_delegate_trampoline): impl.

1441 * debug-stabs.c (write_method_stabs): Don't generate method lines if
1442 we don't have line number information. Use `minfo->method_info.this_offset'
1443 instead of hardcoding 8.

1471 2002-03-23 Martin Baulig <martin@gnome.org>
1473 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1474 to do it before the X86_CMP.
1475 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1476 (reg: CLT (lreg, lreg)): Likewise.
1477 (reg: CLT_UN (lreg, lreg)): Likewise.

1507 removed everything which is already in MonoDebugMethodInfo.
1509 * debug.c (debug_generate_method_lines): Generate the MonoILOffsetInfo array.

1548 * debug.c (mono_debug_get_type): Recursively call this for all function members
1550 (mono_debug_add_method): Don't mangle function names, this must be done by the
1551 debugger backend if the debugging format needs mangled names.
1553 * debug-dwarf2.c: Improved support for classes, added member functions.
1555 2002-03-16 Martin Baulig <martin@gnome.org>
1557 * debug.c (mono_debug_get_type): Recursively call this for all members and
1558 parent classes of a class type.
1560 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1561 since GDB doesn't like Java very much.
1563 2002-03-16 Martin Baulig <martin@gnome.org>
1565 * debug-dwarf2.c: Added support for enums.
1567 2002-03-15 Martin Baulig <martin@gnome.org>

1588 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1590 (mono_debug_open_file): Added MonoDebugFormat argument.
1591 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1592 this function from GDB. It's now safe to call this function multiple times;
1593 it'll always write a complete debugging file.
1595 * debug.c: Splitted this file into a general part which remains in this file
1596 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1597 All public functions now call a corresponding format specific function.
1599 * debug.c: The following changes are private to debug.c:
1600 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1601 (record_line_number, debug_generate_method_lines): New private functions.
1602 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1603 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1604 mono_debug_open_assembly_dwarf2).
1605 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1606 now safe to call this function multiple times.
1607 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1608 returns an unique index for this type. It's used to ensure that we only write
1609 each class once to the debugging file.
1610 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1611 data structure, but don't directly write to the debugging file. This is done
1612 later from mono_debug_write_assembly().
1614 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1615 debugging output. Call mono_debug_close() on cleanup if necessary.
1617 2002-03-14 Martin Baulig <martin@gnome.org>
1619 * debug-private.h: New private header file.
1621 * debug-stabs.c: Added the stabs type generation stuff which was
1622 previously in debug.c.
1624 * debug-dwarf.c: Started to implement type support. We're currently
1625 only writing this most basic types to the dwarf file, but this will
1628 2002-03-13 Martin Baulig <martin@gnome.org>
1630 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1631 debugging code. They're now in CVS, but not yet used anywhere.
1633 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1635 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1636 macros, included new delegate code from Daniel Stodden.
1639 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1641 * jit.c: verify that corlib and runtime are in sync.
1643 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1645 * emit-x86.c, jit.c: use the debug-helpers facilities to
1646 describe and match a method when debugging.
1648 2002-03-10 Martin Baulig <martin@gnome.org>
1650 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1651 output, put a nop instruction at the start of all functions so that
1652 the adresses won't change when using --debug.
1654 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1655 the bytecode area, stabs needs a line number in the .il file. Use the
1656 new info->moffsets to get the line number.
1657 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1658 `moffsets' is an array of `total_lines' fields (total number of lines
1659 in the .il file); for each line in the .il field, this array contains
1660 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1661 of a method and 0 otherwise.
1662 (debug_load_method_lines): Read the whole .il file and initialize the
1663 info->moffsets field.
1665 2002-03-09 Martin Baulig <martin@gnome.org>
1667 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1668 the unnecessary CDQ instruction.
1670 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1672 * jit.c (mono_analyze_stack): only load addresses of value types
1673 on the runtime stack.
1675 2002-03-07 Duncan Mak <duncan@ximian.com>
1677 * Makefile.am: A small patch fixing errors in vpath-based builds
1678 (make clean failing to rerun monoburg due to BUILT_SOURCES usage),
1679 committed for Daniel Stodden <stodden@in.tum.de>.

1713 (x86_magic_trampoline): moved lock/unlock to x86_magic_trampoline
1714 to avoid need of recursive mutexes
1716 * x86.brg: use new mono_assert macros
1718 2002-02-28 Dietmar Maurer <dietmar@ximian.com>

2303 * x86.brg: added some rules to optimize code
2305 * testjit.c (get_address): use a binary search to get the address
2306 (main): added an option to debug the jit (-d)
2308 Tue Sep 18 13:19:16 CEST 2001 Paolo Molaro <lupus@ximian.com>
2310 * testjit.c: better/faster align code. Handle ldloc.s and stloc.s.
2312 2001-09-17 Miguel de Icaza <miguel@ximian.com>
2314 * testjit.c (mono_compile_method): Provide better error reporting.
2316 2001-09-17 Dietmar Maurer <dietmar@ximian.com>
2318 * testjit.c (tree_get_address): impl. to fix address bug
2319 (tree_get_address): make sure that we can only jump to the first
2320 instruction of a tree.
2322 * x86.brg: emit real code for calls
2324 * testjit.c (create_jit_trampoline): creates a function to trigger jit
2326 (mono_compile_method): reversed argument order
2328 2001-09-15 Dietmar Maurer <dietmar@ximian.com>
2330 * x86.brg (stmt): don't emit unnecessary register moves
2332 * testjit.c (tree_allocate_regs): free registers earlier
2334 2001-09-14 Dietmar Maurer <dietmar@ximian.com>
2336 * x86.brg: branch addresses are now resolved
2338 * testjit.c (compute_branches): compute address of branches
2340 * x86.brg: emit real x86 instructions
2342 * testjit.c: call objdump to disassemble the output
2344 2001-09-13 Dietmar Maurer <dietmar@ximian.com>
2346 * x86.brg: use the right offsets to access local variables
2349 * emit-x86.c: only save/restore callee saved registers if they are
2352 * testjit.c (tree_allocate_regs): use the new MonoRegSet to
2354 (mono_compile_method): changed the tree for mothod calls
2361 2001-09-10 Miguel de Icaza <miguel@ximian.com>
2363 * x86.brg: Use Unix assembly syntax.
2365 * emit-x86.c: support code, should be moved
2367 * testjit.c: Use GPtrArrays instead of GLists, as those are very
2368 inefficient at appends.
2370 * Renamed `create_new_leave' to `create_new_leaf'
