1 2002-09-26 Martin Baulig <martin@gnome.org>
3 * debug.c (debug_load_method_lines): Block SIGCHLD while running
6 2002-09-26 Martin Baulig <martin@gnome.org>
8 * debug.c: Reworked the whole debugging stuff. We have now one
9 single `mono_debug_handle' which keeps a hashtable of
10 `AssemblyDebugInfo's (which may have different debugging formats).
11 The AssemblyDebugInfo is now created when the assembly is loaded,
12 but never when adding a class/type.
14 * mono.c: Initialize debugging stuff after corlib and the assembly
17 2002-09-25 Martin Baulig <martin@gnome.org>
19 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
20 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
22 (DebugMethodInfo): Removed `line_numbers'.
24 * debug.c: Reworked the line number generation; we're now using
25 the MonoDebugLineNumberEntry try for all debugging formats. This
26 type also includes the line number and IL offset, this allows the
27 JIT to produce better line number info: we only emit line number
28 information for source lines which actually have code.
30 2002-09-25 Martin Baulig <martin@gnome.org>
32 * debug.h: Removed external declaration of all functions which
33 should only be called from the Mono Debugger and also made them
34 static. Since the debugger gets their address from the
35 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
38 2002-09-25 Martin Baulig <martin@gnome.org>
40 Improved breakpoint support, we can now dynamically insert and
41 remove breakpoints at runtime and when called from withing the
42 Mono Debugger, we're using a special breakpoint trampoline.
44 * debug.h (mono_method_has_breakpoint): New method to check
45 whether to insert a breakpoint for a method.
46 (mono_insert_breakpoint): New method to insert a breakpoint.
47 (mono_insert_breakpoint_full): New method to insert a breakpoint,
48 takes a MonoMethodDesc.
49 (mono_remove_breakpoint): New method to remove a breakpoint.
51 * debug.c (mono_debugger_insert_breakpoint): New function for the
52 debugger. Should only be called from the debugger.
53 (mono_debugger_remove_breakpoint): Likewise.
55 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
57 * trampoline.c (get_breakpoint_trampoline): New static function to
58 create a special breakpoint trampoline for the debugger.
59 (x86_magic_trampoline): If we're running inside the Mono Debugger
60 and a breakpoint was requested for the method, generate a special
61 breakpoint trampoline.
63 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
64 to insert a breakpoint.
65 (mono_debug_last_breakpoint_address): Removed.
66 (match_debug_method): Removed, use mono_method_has_breakpoint().
68 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
70 * jit.c: reorder mono_runtime_cleanup () call since it needs the
71 engine still fully working.
73 2002-09-24 Martin Baulig <martin@gnome.org>
75 * debug.c (mono_debug_open): When we're invoked from inside the
76 Mono Debugger, set mono_debugger_class_init_func (exported in
77 metadata/class.c) to mono_add_type().
78 (mono_add_type): Call mono_debug_symfile_add_type().
80 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
82 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
83 Run finalize on domain cleanup.

85 * trampoline.c: clearer error message for invalid trampoline.
87 2002-09-21 Martin Baulig <martin@gnome.org>
89 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
90 instead of writing a byte blob.
91 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
92 (mono_debug_add_method): Incrementally add the new method to the symbol
95 * exception.c (arch_handle_exception): If we have debugging support,
96 call mono_debugger_update_symbol_file_table () as well.
98 2002-09-20 Martin Baulig <martin@gnome.org>
100 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
101 the size of the variable.
103 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
105 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
106 iterations if we visit blocks in reverse order.
108 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
110 * jit.c (mono_analyze_stack): cleaup of the array code
112 * exception.c: added patch from Julio Merno to fix bug #30048

118 * x86.brg (LDELEMA): use x86_lea
120 2002-09-06 Martin Baulig <martin@gnome.org>
122 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
123 If you were getting random crashes when using the JIT with debugging
124 turned on, this fixes it.
126 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
128 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
130 2002-09-05 Martin Baulig <martin@gnome.org>
132 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
133 which is read by the debugger.
135 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>

149 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
150 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
151 `mono_symfile' to `symfile'.
153 * debug.c (mono_debug_open): Replaced the assembly argument with a
154 file name argument; you can now call this before loading the assembly.
155 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
156 we now use MonoSymbolFileLineNumberEntry's and a separate address array
157 instead; splitted out all MonoSymbolFileLineNumberEntry code into
158 debug_generate_il_offsets() and debug_update_il_offsets().
159 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
160 created when reading the symbol file or from debug_load_method_lines().
161 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
163 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before
164 looking up an address.

187 * mono.c: don't use the cil-coff header outside of the loader.
189 2002-08-27 Martin Baulig <martin@gnome.org>
191 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need

201 (arch_create_jit_trampoline): Use the new global variable to store the
202 generic trampoline code instead of using a static one. This allows the
203 debugger to access this variable to check whether a method is a trampoline.

210 AssemblyDebugInfo struct since we need to use a separate hash for each
213 * debug.c: Added special undocumented command line argument to create a
214 symbol file for IL files on-the-fly. In this case, we also need to create
215 the IL files and parse them.

636 the assembler if necessary, ie. the assembler file is newer than the
637 symbol file or the symbol file does not exist.
639 * debug.c: Added "update_on_exit" argument to recreate the symbol file
642 * debug-dwarf2.c: Produce assembler code which is free of comments and

737 2002-05-21 Martin Baulig <martin@gnome.org>
739 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
740 file for all assemblies. Currently, the JIT doesn't put all methods
741 from a single assembly into a continuous region of memory. We were
742 previously creating valid DWARF 2 files for this, but unfortunately
743 GDB's symbol tables get messed up when it reads more than one such file.
745 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

1190 `mono_debug_last_breakpoint_address', also documented them here.
1192 2002-03-28 Martin Baulig <martin@gnome.org>
1194 * debug-private.h (MonoDebugHandle): Renamed `format' to `default_format'.
1195 (AssemblyDebugInfo): Added `format'.
1197 * debug.c: Use the AssemblyDebugInfo's `format' field to determine the format,
1198 this allows us choose the format on a per-assembly basis.
1199 (mono_debug_open_assembly): When using MONO_DEBUG_FORMAT_DWARF2_PLUS, fall back
1200 to MONO_DEBUG_FORMAT_DWARF2 if the symbol file does not exist, but the IL file

1211 `prologue_end_offset', added `epilogue_begin_offset' and `last_line'.
1213 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1214 numbers, we still need to generate the IL offsets here. Emit line numbers
1215 for `prologue_end_offset' (the first line of actual code) and
1216 `epilogue_begin_offset' (the line of the method's closing brace).
1217 Don't crash if cfg->bblocks [i].forest is NULL.
1218 (mono_debug_add_method): Don't crash if we don't have line numbers.
1219 Initialize the newly added fields.
1221 * debug-stabs.c: Record first and last line, emit filename info at the
1222 beginning of the stab file, gdb ignores the types otherwise.
1224 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1225 emit line number info for the first and last line.
1227 2002-03-28 Dietmar Maurer <dietmar@ximian.com>
1229 * invoke.c (arch_create_delegate_trampoline): impl.

1258 (write_method_dwarf2): Use `minfo->method_info.this_offset' instead
1261 * debug-stabs.c (write_method_stabs): Don't generate method lines if
1262 we don't have line number information. Use `minfo->method_info.this_offset'
1263 instead of hardcoding 8.

1268 MONO_DEBUG_FORMAT_DWARF2_PLUS.
1269 (mono_debug_add_method): Don't store the 'this' offset in `param_offsets',

1282 2002-03-25 Martin Baulig <martin@gnome.org>
1284 * debug.h (mono_debug_make_symbols): Documented this function.
1286 2002-03-24 Martin Baulig <martin@gnome.org>
1288 * debug.c (mono_debug_add_method): Include the `this' offset in
1289 the `minfo->method_info.param_offsets' array.
1291 2002-03-23 Martin Baulig <martin@gnome.org>
1293 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1294 to do it before the X86_CMP.
1295 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1296 (reg: CLT (lreg, lreg)): Likewise.
1297 (reg: CLT_UN (lreg, lreg)): Likewise.

1373 * debug-dwarf2.c: Improved support for classes, added member functions.
1375 2002-03-16 Martin Baulig <martin@gnome.org>
1377 * debug.c (mono_debug_get_type): Recursively call this for all members and
1378 parent classes of a class type.
1380 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1381 since GDB doesn't like Java very much.
1383 2002-03-16 Martin Baulig <martin@gnome.org>
1385 * debug-dwarf2.c: Added support for enums.
1387 2002-03-15 Martin Baulig <martin@gnome.org>

1408 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1410 (mono_debug_open_file): Added MonoDebugFormat argument.
1411 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1412 this function from GDB. It's now safe to call this function multiple times;
1413 it'll always write a complete debugging file.
1415 * debug.c: Splitted this file into a general part which remains in this file
1416 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1417 All public functions now call a corresponding format specific function.
1419 * debug.c: The following changes are private to debug.c:
1420 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1421 (record_line_number, debug_generate_method_lines): New private functions.
1422 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1423 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1424 mono_debug_open_assembly_dwarf2).
1425 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1426 now safe to call this function multiple times.
1427 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1428 returns an unique index for this type. It's used to ensure that we only write
1429 each class once to the debugging file.
1430 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1431 data structure, but don't directly write to the debugging file. This is done
1432 later from mono_debug_write_assembly().
1434 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1435 debugging output. Call mono_debug_close() on cleanup if necessary.
1437 2002-03-14 Martin Baulig <martin@gnome.org>
1439 * debug-private.h: New private header file.
1441 * debug-stabs.c: Added the stabs type generation stuff which was
1442 previously in debug.c.
1444 * debug-dwarf.c: Started to implement type support. We're currently
1445 only writing this most basic types to the dwarf file, but this will
1448 2002-03-13 Martin Baulig <martin@gnome.org>
1450 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1451 debugging code. They're now in CVS, but not yet used anywhere.
1453 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1455 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1456 macros, included new delegate code from Daniel Stodden.
1459 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1461 * jit.c: verify that corlib and runtime are in sync.
1463 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1465 * emit-x86.c, jit.c: use the debug-helpers facilities to
1466 describe and match a method when debugging.
1468 2002-03-10 Martin Baulig <martin@gnome.org>
1470 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1471 output, put a nop instruction at the start of all functions so that
1472 the adresses won't change when using --debug.
1474 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1475 the bytecode area, stabs needs a line number in the .il file. Use the
1476 new info->moffsets to get the line number.
1477 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1478 `moffsets' is an array of `total_lines' fields (total number of lines
1479 in the .il file); for each line in the .il field, this array contains
1480 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1481 of a method and 0 otherwise.
1482 (debug_load_method_lines): Read the whole .il file and initialize the
1483 info->moffsets field.
1485 2002-03-09 Martin Baulig <martin@gnome.org>
1487 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1488 the unnecessary CDQ instruction.
1490 2002-03-07 Dietmar Maurer <dietmar@ximian.com>

1493 on the runtime stack.
1495 2002-03-07 Duncan Mak <duncan@ximian.com>
