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

80 * trampoline.c: clearer error message for invalid trampoline.
82 2002-09-21 Martin Baulig <martin@gnome.org>
84 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
85 instead of writing a byte blob.
86 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
87 (mono_debug_add_method): Incrementally add the new method to the symbol
90 * exception.c (arch_handle_exception): If we have debugging support,
91 call mono_debugger_update_symbol_file_table () as well.
93 2002-09-20 Martin Baulig <martin@gnome.org>
95 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
96 the size of the variable.
98 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
100 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
101 iterations if we visit blocks in reverse order.
103 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
105 * jit.c (mono_analyze_stack): cleaup of the array code
107 * exception.c: added patch from Julio Merno to fix bug #30048

115 2002-09-06 Martin Baulig <martin@gnome.org>
117 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
118 If you were getting random crashes when using the JIT with debugging
119 turned on, this fixes it.
121 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
123 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
125 2002-09-05 Martin Baulig <martin@gnome.org>
127 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
128 which is read by the debugger.
130 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>

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

182 * mono.c: don't use the cil-coff header outside of the loader.
184 2002-08-27 Martin Baulig <martin@gnome.org>
186 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need

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

202 2002-08-27 Martin Baulig <martin@gnome.org>
204 * debug.c (MonoDebugHandle): Moved the method hash into the
205 AssemblyDebugInfo struct since we need to use a separate hash for each
208 * debug.c: Added special undocumented command line argument to create a
209 symbol file for IL files on-the-fly. In this case, we also need to create
210 the IL files and parse them.

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

732 2002-05-21 Martin Baulig <martin@gnome.org>
734 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
735 file for all assemblies. Currently, the JIT doesn't put all methods
736 from a single assembly into a continuous region of memory. We were
737 previously creating valid DWARF 2 files for this, but unfortunately
738 GDB's symbol tables get messed up when it reads more than one such file.
740 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',
741 `next_idx', `methods', `type_hash', `source_files' and `format'
742 into the MonoDebugHandle.

1187 2002-03-28 Martin Baulig <martin@gnome.org>
1189 * debug-private.h (MonoDebugHandle): Renamed `format' to `default_format'.
1190 (AssemblyDebugInfo): Added `format'.
1192 * debug.c: Use the AssemblyDebugInfo's `format' field to determine the format,
1193 this allows us choose the format on a per-assembly basis.
1194 (mono_debug_open_assembly): When using MONO_DEBUG_FORMAT_DWARF2_PLUS, fall back
1195 to MONO_DEBUG_FORMAT_DWARF2 if the symbol file does not exist, but the IL file

1208 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1209 numbers, we still need to generate the IL offsets here. Emit line numbers
1210 for `prologue_end_offset' (the first line of actual code) and
1211 `epilogue_begin_offset' (the line of the method's closing brace).
1212 Don't crash if cfg->bblocks [i].forest is NULL.
1213 (mono_debug_add_method): Don't crash if we don't have line numbers.
1214 Initialize the newly added fields.
1216 * debug-stabs.c: Record first and last line, emit filename info at the
1217 beginning of the stab file, gdb ignores the types otherwise.
1219 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1220 emit line number info for the first and last line.
1222 2002-03-28 Dietmar Maurer <dietmar@ximian.com>
1224 * invoke.c (arch_create_delegate_trampoline): impl.
1226 Thu Mar 28 11:58:53 CET 2002 Paolo Molaro <lupus@ximian.com>

1252 lines if we don't have line number information.
1253 (write_method_dwarf2): Use `minfo->method_info.this_offset' instead
1256 * debug-stabs.c (write_method_stabs): Don't generate method lines if
1257 we don't have line number information. Use `minfo->method_info.this_offset'
1258 instead of hardcoding 8.
1260 * debug.c (debug_generate_method_lines): Don't crash if we don't have
1261 line number information.
1262 (mono_debug_open_assembly): Don't generate line numbers for
1263 MONO_DEBUG_FORMAT_DWARF2_PLUS.
1264 (mono_debug_add_method): Don't store the 'this' offset in `param_offsets',
1265 but it in the new `this_offset' field.

1277 2002-03-25 Martin Baulig <martin@gnome.org>
1279 * debug.h (mono_debug_make_symbols): Documented this function.
1281 2002-03-24 Martin Baulig <martin@gnome.org>
1283 * debug.c (mono_debug_add_method): Include the `this' offset in
1284 the `minfo->method_info.param_offsets' array.
1286 2002-03-23 Martin Baulig <martin@gnome.org>
1288 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1289 to do it before the X86_CMP.
1290 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1291 (reg: CLT (lreg, lreg)): Likewise.
1292 (reg: CLT_UN (lreg, lreg)): Likewise.

1304 (mono_debug_open_assembly_dwarf2_plus): Open the symbol file here.
1305 (mono_debug_close_assembly_dwarf2_plus): Close the symbol file here.
1306 (mono_debug_write_assembly_dwarf2_plus): Only call

1368 * debug-dwarf2.c: Improved support for classes, added member functions.
1370 2002-03-16 Martin Baulig <martin@gnome.org>
1372 * debug.c (mono_debug_get_type): Recursively call this for all members and
1373 parent classes of a class type.
1375 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1376 since GDB doesn't like Java very much.
1378 2002-03-16 Martin Baulig <martin@gnome.org>
1380 * debug-dwarf2.c: Added support for enums.
1382 2002-03-15 Martin Baulig <martin@gnome.org>

1403 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1405 (mono_debug_open_file): Added MonoDebugFormat argument.
1406 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1407 this function from GDB. It's now safe to call this function multiple times;
1408 it'll always write a complete debugging file.
1410 * debug.c: Splitted this file into a general part which remains in this file
1411 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1412 All public functions now call a corresponding format specific function.
1414 * debug.c: The following changes are private to debug.c:
1415 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1416 (record_line_number, debug_generate_method_lines): New private functions.
1417 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1418 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1419 mono_debug_open_assembly_dwarf2).
1420 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1421 now safe to call this function multiple times.
1422 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1423 returns an unique index for this type. It's used to ensure that we only write
1424 each class once to the debugging file.
1425 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1426 data structure, but don't directly write to the debugging file. This is done
1427 later from mono_debug_write_assembly().
1429 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1430 debugging output. Call mono_debug_close() on cleanup if necessary.
1432 2002-03-14 Martin Baulig <martin@gnome.org>
1434 * debug-private.h: New private header file.
1436 * debug-stabs.c: Added the stabs type generation stuff which was
1437 previously in debug.c.
1439 * debug-dwarf.c: Started to implement type support. We're currently
1440 only writing this most basic types to the dwarf file, but this will
1443 2002-03-13 Martin Baulig <martin@gnome.org>
1445 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1446 debugging code. They're now in CVS, but not yet used anywhere.
1448 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1450 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1451 macros, included new delegate code from Daniel Stodden.
1454 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1456 * jit.c: verify that corlib and runtime are in sync.
1458 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1460 * emit-x86.c, jit.c: use the debug-helpers facilities to
1461 describe and match a method when debugging.
1463 2002-03-10 Martin Baulig <martin@gnome.org>
1465 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1466 output, put a nop instruction at the start of all functions so that
1467 the adresses won't change when using --debug.
1469 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1470 the bytecode area, stabs needs a line number in the .il file. Use the
1471 new info->moffsets to get the line number.
1472 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1473 `moffsets' is an array of `total_lines' fields (total number of lines
1474 in the .il file); for each line in the .il field, this array contains
1475 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1476 of a method and 0 otherwise.
1477 (debug_load_method_lines): Read the whole .il file and initialize the
1478 info->moffsets field.
1480 2002-03-09 Martin Baulig <martin@gnome.org>
1482 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1483 the unnecessary CDQ instruction.
1485 2002-03-07 Dietmar Maurer <dietmar@ximian.com>

1488 on the runtime stack.
1490 2002-03-07 Duncan Mak <duncan@ximian.com>
