1 2002-10-01 Martin Baulig <martin@gnome.org>
3 * debug.c (MonoDebuggerInfo): Added mono_runtime_invoke().
5 2002-09-27 Martin Baulig <martin@gnome.org>
7 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
9 2002-09-27 Dick Porter <dick@ximian.com>
11 * mono.c: Tell glib what the program name is, by passing it the
12 name of the managed file we're executing
14 2002-09-26 Martin Baulig <martin@gnome.org>
16 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
17 trampoline into the vtable, also use it for non-virtual methods,
18 remove the breakpoint when done.
20 2002-09-26 Martin Baulig <martin@gnome.org>
22 * debug.c (debug_load_method_lines): Block SIGCHLD while running
25 2002-09-26 Martin Baulig <martin@gnome.org>
27 * debug.c: Reworked the whole debugging stuff. We have now one
28 single `mono_debug_handle' which keeps a hashtable of
29 `AssemblyDebugInfo's (which may have different debugging formats).
30 The AssemblyDebugInfo is now created when the assembly is loaded,
31 but never when adding a class/type.
33 * mono.c: Initialize debugging stuff after corlib and the assembly
36 2002-09-25 Martin Baulig <martin@gnome.org>
38 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
39 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
41 (DebugMethodInfo): Removed `line_numbers'.
43 * debug.c: Reworked the line number generation; we're now using
44 the MonoDebugLineNumberEntry try for all debugging formats. This
45 type also includes the line number and IL offset, this allows the
46 JIT to produce better line number info: we only emit line number
47 information for source lines which actually have code.
49 2002-09-25 Martin Baulig <martin@gnome.org>
51 * debug.h: Removed external declaration of all functions which
52 should only be called from the Mono Debugger and also made them
53 static. Since the debugger gets their address from the
54 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
57 2002-09-25 Martin Baulig <martin@gnome.org>
59 Improved breakpoint support, we can now dynamically insert and
60 remove breakpoints at runtime and when called from withing the
61 Mono Debugger, we're using a special breakpoint trampoline.
63 * debug.h (mono_method_has_breakpoint): New method to check
64 whether to insert a breakpoint for a method.
65 (mono_insert_breakpoint): New method to insert a breakpoint.
66 (mono_insert_breakpoint_full): New method to insert a breakpoint,
67 takes a MonoMethodDesc.
68 (mono_remove_breakpoint): New method to remove a breakpoint.
70 * debug.c (mono_debugger_insert_breakpoint): New function for the
71 debugger. Should only be called from the debugger.
72 (mono_debugger_remove_breakpoint): Likewise.
74 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
76 * trampoline.c (get_breakpoint_trampoline): New static function to
77 create a special breakpoint trampoline for the debugger.
78 (x86_magic_trampoline): If we're running inside the Mono Debugger
79 and a breakpoint was requested for the method, generate a special
80 breakpoint trampoline.
82 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
83 to insert a breakpoint.
84 (mono_debug_last_breakpoint_address): Removed.
85 (match_debug_method): Removed, use mono_method_has_breakpoint().
87 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
89 * jit.c: reorder mono_runtime_cleanup () call since it needs the
90 engine still fully working.
92 2002-09-24 Martin Baulig <martin@gnome.org>
94 * debug.c (mono_debug_open): When we're invoked from inside the
95 Mono Debugger, set mono_debugger_class_init_func (exported in
96 metadata/class.c) to mono_add_type().
97 (mono_add_type): Call mono_debug_symfile_add_type().
99 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
101 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
102 Run finalize on domain cleanup.
103 * mono.c: call setlocale ().
104 * trampoline.c: clearer error message for invalid trampoline.
106 2002-09-21 Martin Baulig <martin@gnome.org>
108 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
109 instead of writing a byte blob.
110 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
111 (mono_debug_add_method): Incrementally add the new method to the symbol
114 * exception.c (arch_handle_exception): If we have debugging support,
115 call mono_debugger_update_symbol_file_table () as well.
117 2002-09-20 Martin Baulig <martin@gnome.org>
119 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
120 the size of the variable.
122 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
124 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
125 iterations if we visit blocks in reverse order.
127 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
129 * jit.c (mono_analyze_stack): cleaup of the array code
131 * exception.c: added patch from Julio Merno to fix bug #30048

135 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
137 * x86.brg (LDELEMA): use x86_lea
139 2002-09-06 Martin Baulig <martin@gnome.org>
141 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
142 If you were getting random crashes when using the JIT with debugging
143 turned on, this fixes it.
145 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
147 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
149 2002-09-05 Martin Baulig <martin@gnome.org>
151 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
152 which is read by the debugger.
154 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>

168 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
169 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
170 `mono_symfile' to `symfile'.
172 * debug.c (mono_debug_open): Replaced the assembly argument with a
173 file name argument; you can now call this before loading the assembly.
174 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
175 we now use MonoSymbolFileLineNumberEntry's and a separate address array
176 instead; splitted out all MonoSymbolFileLineNumberEntry code into
177 debug_generate_il_offsets() and debug_update_il_offsets().
178 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
179 created when reading the symbol file or from debug_load_method_lines().
180 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
182 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before
183 looking up an address.

206 * mono.c: don't use the cil-coff header outside of the loader.
208 2002-08-27 Martin Baulig <martin@gnome.org>
210 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need

226 2002-08-27 Martin Baulig <martin@gnome.org>
228 * debug.c (MonoDebugHandle): Moved the method hash into the
229 AssemblyDebugInfo struct since we need to use a separate hash for each
232 * debug.c: Added special undocumented command line argument to create a
233 symbol file for IL files on-the-fly. In this case, we also need to create
234 the IL files and parse them.

656 symbol file or the symbol file does not exist.
658 * debug.c: Added "update_on_exit" argument to recreate the symbol file
661 * debug-dwarf2.c: Produce assembler code which is free of comments and

714 a `MonoAssembly *' argument instead of a `char *filename' one. Also added
715 `const char **args' argument.
717 * mono.c (mono_jit_assembly): Renamed to mono_jit_compile_image(), added
718 `int verbose' argument and made it public.

756 2002-05-21 Martin Baulig <martin@gnome.org>
758 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
759 file for all assemblies. Currently, the JIT doesn't put all methods
760 from a single assembly into a continuous region of memory. We were
761 previously creating valid DWARF 2 files for this, but unfortunately
762 GDB's symbol tables get messed up when it reads more than one such file.
764 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

1205 Set `mono_debug_last_breakpoint_address' to the address of the last inserted
1208 * debug.h: Provide external declaration of `mono_debug_insert_breakpoint' and
1209 `mono_debug_last_breakpoint_address', also documented them here.
1211 2002-03-28 Martin Baulig <martin@gnome.org>
1213 * debug-private.h (MonoDebugHandle): Renamed `format' to `default_format'.
1214 (AssemblyDebugInfo): Added `format'.

1232 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1233 numbers, we still need to generate the IL offsets here. Emit line numbers
1234 for `prologue_end_offset' (the first line of actual code) and
1235 `epilogue_begin_offset' (the line of the method's closing brace).
1236 Don't crash if cfg->bblocks [i].forest is NULL.
1237 (mono_debug_add_method): Don't crash if we don't have line numbers.
1238 Initialize the newly added fields.
1240 * debug-stabs.c: Record first and last line, emit filename info at the

1243 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1244 emit line number info for the first and last line.
1246 2002-03-28 Dietmar Maurer <dietmar@ximian.com>
1248 * invoke.c (arch_create_delegate_trampoline): impl.

1280 * debug-stabs.c (write_method_stabs): Don't generate method lines if
1281 we don't have line number information. Use `minfo->method_info.this_offset'
1282 instead of hardcoding 8.

1305 2002-03-24 Martin Baulig <martin@gnome.org>
1307 * debug.c (mono_debug_add_method): Include the `this' offset in
1308 the `minfo->method_info.param_offsets' array.
1310 2002-03-23 Martin Baulig <martin@gnome.org>
1312 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1313 to do it before the X86_CMP.
1314 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1315 (reg: CLT (lreg, lreg)): Likewise.

1394 2002-03-16 Martin Baulig <martin@gnome.org>
1396 * debug.c (mono_debug_get_type): Recursively call this for all members and
1397 parent classes of a class type.
1399 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1400 since GDB doesn't like Java very much.
1402 2002-03-16 Martin Baulig <martin@gnome.org>
1404 * debug-dwarf2.c: Added support for enums.
1406 2002-03-15 Martin Baulig <martin@gnome.org>

1427 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1429 (mono_debug_open_file): Added MonoDebugFormat argument.
1430 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1431 this function from GDB. It's now safe to call this function multiple times;
1432 it'll always write a complete debugging file.
1434 * debug.c: Splitted this file into a general part which remains in this file
1435 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1436 All public functions now call a corresponding format specific function.
1438 * debug.c: The following changes are private to debug.c:
1439 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1440 (record_line_number, debug_generate_method_lines): New private functions.
1441 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1442 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1443 mono_debug_open_assembly_dwarf2).
1444 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1445 now safe to call this function multiple times.
1446 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1447 returns an unique index for this type. It's used to ensure that we only write
1448 each class once to the debugging file.
1449 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1450 data structure, but don't directly write to the debugging file. This is done
1451 later from mono_debug_write_assembly().
1453 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1454 debugging output. Call mono_debug_close() on cleanup if necessary.
1456 2002-03-14 Martin Baulig <martin@gnome.org>
1458 * debug-private.h: New private header file.
1460 * debug-stabs.c: Added the stabs type generation stuff which was
1461 previously in debug.c.
1463 * debug-dwarf.c: Started to implement type support. We're currently
1464 only writing this most basic types to the dwarf file, but this will
1467 2002-03-13 Martin Baulig <martin@gnome.org>
1469 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1470 debugging code. They're now in CVS, but not yet used anywhere.
1472 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1474 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1475 macros, included new delegate code from Daniel Stodden.
1478 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1480 * jit.c: verify that corlib and runtime are in sync.
1482 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1484 * emit-x86.c, jit.c: use the debug-helpers facilities to
1485 describe and match a method when debugging.
1487 2002-03-10 Martin Baulig <martin@gnome.org>
1489 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1490 output, put a nop instruction at the start of all functions so that
1491 the adresses won't change when using --debug.
1493 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1494 the bytecode area, stabs needs a line number in the .il file. Use the
1495 new info->moffsets to get the line number.
1496 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1497 `moffsets' is an array of `total_lines' fields (total number of lines
1498 in the .il file); for each line in the .il field, this array contains
1499 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1500 of a method and 0 otherwise.
1501 (debug_load_method_lines): Read the whole .il file and initialize the
1502 info->moffsets field.
1504 2002-03-09 Martin Baulig <martin@gnome.org>
1506 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1507 the unnecessary CDQ instruction.
1509 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
