1 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
3 * exception.c: massive code cleanups. The code is still
4 architecture dependent, but it should be now possible to reuse the
5 complex parts for other architecture.
7 2002-11-15 Dick Porter <dick@ximian.com>
9 * jit.c: Pass the attach callback to mono_runtime_init().
11 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
13 * jit.c: display the domain name in trace output.
15 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
17 * x86.brg (reg): fix bug #2721
19 * jit.c (mono_runtime_install_handlers): impl.
21 2002-10-17 Martin Baulig <martin@gnome.org>

24 have any lifetime information.
26 2002-10-15 Martin Baulig <martin@gnome.org>
28 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
30 * debug.c (generate_line_number): Small fix to make this actually
31 work for more complex things.
33 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
35 * x86.brg (freg): use fprem instead of fprem1
37 2002-10-03 Dietmar Maurer <dietmar@ximian.com>

40 (mono_analyze_stack): added fix for bug #31654
42 2002-10-01 Martin Baulig <martin@gnome.org>
44 * debug.c: Don't create an .il file for the dynamic symbol file.
46 2002-10-01 Martin Baulig <martin@gnome.org>

57 name of the managed file we're executing
59 2002-09-26 Martin Baulig <martin@gnome.org>
61 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
62 trampoline into the vtable, also use it for non-virtual methods,
63 remove the breakpoint when done.
65 2002-09-26 Martin Baulig <martin@gnome.org>
67 * debug.c (debug_load_method_lines): Block SIGCHLD while running
70 2002-09-26 Martin Baulig <martin@gnome.org>
72 * debug.c: Reworked the whole debugging stuff. We have now one
73 single `mono_debug_handle' which keeps a hashtable of
74 `AssemblyDebugInfo's (which may have different debugging formats).
75 The AssemblyDebugInfo is now created when the assembly is loaded,
76 but never when adding a class/type.
78 * mono.c: Initialize debugging stuff after corlib and the assembly
81 2002-09-25 Martin Baulig <martin@gnome.org>

84 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
86 (DebugMethodInfo): Removed `line_numbers'.
88 * debug.c: Reworked the line number generation; we're now using
89 the MonoDebugLineNumberEntry try for all debugging formats. This
90 type also includes the line number and IL offset, this allows the
91 JIT to produce better line number info: we only emit line number
92 information for source lines which actually have code.
94 2002-09-25 Martin Baulig <martin@gnome.org>
96 * debug.h: Removed external declaration of all functions which
97 should only be called from the Mono Debugger and also made them
98 static. Since the debugger gets their address from the
99 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
102 2002-09-25 Martin Baulig <martin@gnome.org>
104 Improved breakpoint support, we can now dynamically insert and
105 remove breakpoints at runtime and when called from withing the
106 Mono Debugger, we're using a special breakpoint trampoline.

109 whether to insert a breakpoint for a method.
110 (mono_insert_breakpoint): New method to insert a breakpoint.
111 (mono_insert_breakpoint_full): New method to insert a breakpoint,
112 takes a MonoMethodDesc.
113 (mono_remove_breakpoint): New method to remove a breakpoint.
115 * debug.c (mono_debugger_insert_breakpoint): New function for the
116 debugger. Should only be called from the debugger.
117 (mono_debugger_remove_breakpoint): Likewise.
119 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
121 * trampoline.c (get_breakpoint_trampoline): New static function to
122 create a special breakpoint trampoline for the debugger.
123 (x86_magic_trampoline): If we're running inside the Mono Debugger
124 and a breakpoint was requested for the method, generate a special
125 breakpoint trampoline.
127 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
128 to insert a breakpoint.
129 (mono_debug_last_breakpoint_address): Removed.
130 (match_debug_method): Removed, use mono_method_has_breakpoint().
132 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
134 * jit.c: reorder mono_runtime_cleanup () call since it needs the
135 engine still fully working.
137 2002-09-24 Martin Baulig <martin@gnome.org>
139 * debug.c (mono_debug_open): When we're invoked from inside the
140 Mono Debugger, set mono_debugger_class_init_func (exported in
141 metadata/class.c) to mono_add_type().
142 (mono_add_type): Call mono_debug_symfile_add_type().
144 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
146 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
147 Run finalize on domain cleanup.
148 * mono.c: call setlocale ().
149 * trampoline.c: clearer error message for invalid trampoline.
151 2002-09-21 Martin Baulig <martin@gnome.org>
153 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
154 instead of writing a byte blob.
155 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
156 (mono_debug_add_method): Incrementally add the new method to the symbol
159 * exception.c (arch_handle_exception): If we have debugging support,
160 call mono_debugger_update_symbol_file_table () as well.
162 2002-09-20 Martin Baulig <martin@gnome.org>
164 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
165 the size of the variable.
167 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
169 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
170 iterations if we visit blocks in reverse order.
172 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
174 * jit.c (mono_analyze_stack): cleaup of the array code
176 * exception.c: added patch from Julio Merno to fix bug #30048

180 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
182 * x86.brg (LDELEMA): use x86_lea
184 2002-09-06 Martin Baulig <martin@gnome.org>
186 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
187 If you were getting random crashes when using the JIT with debugging
188 turned on, this fixes it.
190 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
192 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
194 2002-09-05 Martin Baulig <martin@gnome.org>
196 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
197 which is read by the debugger.
199 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>

211 * debug-dwarf2-plus.c: Removed.
213 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
214 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
215 `mono_symfile' to `symfile'.
217 * debug.c (mono_debug_open): Replaced the assembly argument with a
218 file name argument; you can now call this before loading the assembly.
219 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
220 we now use MonoSymbolFileLineNumberEntry's and a separate address array
221 instead; splitted out all MonoSymbolFileLineNumberEntry code into
222 debug_generate_il_offsets() and debug_update_il_offsets().
223 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
224 created when reading the symbol file or from debug_load_method_lines().
225 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
227 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before

251 * mono.c: don't use the cil-coff header outside of the loader.
253 2002-08-27 Martin Baulig <martin@gnome.org>
255 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need

267 debugger to access this variable to check whether a method is a trampoline.
269 * debug.h (mono_generic_trampoline_code): Added external declaration.
271 2002-08-27 Martin Baulig <martin@gnome.org>
273 * debug.c (MonoDebugHandle): Moved the method hash into the
274 AssemblyDebugInfo struct since we need to use a separate hash for each
277 * debug.c: Added special undocumented command line argument to create a
278 symbol file for IL files on-the-fly. In this case, we also need to create
279 the IL files and parse them.

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

801 2002-05-21 Martin Baulig <martin@gnome.org>
803 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
804 file for all assemblies. Currently, the JIT doesn't put all methods
805 from a single assembly into a continuous region of memory. We were
806 previously creating valid DWARF 2 files for this, but unfortunately
807 GDB's symbol tables get messed up when it reads more than one such file.
809 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

1190 * invoke.c (arch_create_native_wrapper): special case EndInvoke -
1191 we need to pass the MonoMethod pointer as first argument.
1193 * delegate.c (mono_async_invoke): notify all listeners, not only a
1195 (arch_end_invoke): we now pass a MonoMethod as first parameter and
1196 use arch_method_call_message_new() to access the stack.
1197 (arch_end_invoke): wait until we really finished processing
1198 (async_invoke_abort): notify all listeners, not only a
1201 2002-04-06 Dietmar Maurer <dietmar@ximian.com>

1250 Set `mono_debug_last_breakpoint_address' to the address of the last inserted
1253 * debug.h: Provide external declaration of `mono_debug_insert_breakpoint' and
1254 `mono_debug_last_breakpoint_address', also documented them here.

1258 * debug-private.h (MonoDebugHandle): Renamed `format' to `default_format'.
1259 (AssemblyDebugInfo): Added `format'.
1261 * debug.c: Use the AssemblyDebugInfo's `format' field to determine the format,
1262 this allows us choose the format on a per-assembly basis.
1263 (mono_debug_open_assembly): When using MONO_DEBUG_FORMAT_DWARF2_PLUS, fall back
1264 to MONO_DEBUG_FORMAT_DWARF2 if the symbol file does not exist, but the IL file

1275 `prologue_end_offset', added `epilogue_begin_offset' and `last_line'.
1277 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1278 numbers, we still need to generate the IL offsets here. Emit line numbers
1279 for `prologue_end_offset' (the first line of actual code) and
1280 `epilogue_begin_offset' (the line of the method's closing brace).
1281 Don't crash if cfg->bblocks [i].forest is NULL.
1282 (mono_debug_add_method): Don't crash if we don't have line numbers.
1283 Initialize the newly added fields.
1285 * debug-stabs.c: Record first and last line, emit filename info at the
1286 beginning of the stab file, gdb ignores the types otherwise.
1288 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1289 emit line number info for the first and last line.
1291 2002-03-28 Dietmar Maurer <dietmar@ximian.com>
1293 * invoke.c (arch_create_delegate_trampoline): impl.
1295 Thu Mar 28 11:58:53 CET 2002 Paolo Molaro <lupus@ximian.com>
1297 * Makefile.am, mono.c, jit.h, jit.c: build the libmono library

1299 * jit.c: use opcode names from libmetadata.
1300 * debug.h, debug.c: constify char* argument.
1302 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

1321 lines if we don't have line number information.
1322 (write_method_dwarf2): Use `minfo->method_info.this_offset' instead
1325 * debug-stabs.c (write_method_stabs): Don't generate method lines if
1326 we don't have line number information. Use `minfo->method_info.this_offset'
1327 instead of hardcoding 8.
1329 * debug.c (debug_generate_method_lines): Don't crash if we don't have
1330 line number information.
1331 (mono_debug_open_assembly): Don't generate line numbers for
1332 MONO_DEBUG_FORMAT_DWARF2_PLUS.
1333 (mono_debug_add_method): Don't store the 'this' offset in `param_offsets',
1334 but it in the new `this_offset' field.

1346 2002-03-25 Martin Baulig <martin@gnome.org>
1348 * debug.h (mono_debug_make_symbols): Documented this function.
1350 2002-03-24 Martin Baulig <martin@gnome.org>
1352 * debug.c (mono_debug_add_method): Include the `this' offset in
1353 the `minfo->method_info.param_offsets' array.
1355 2002-03-23 Martin Baulig <martin@gnome.org>
1357 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1358 to do it before the X86_CMP.
1359 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1360 (reg: CLT (lreg, lreg)): Likewise.
1361 (reg: CLT_UN (lreg, lreg)): Likewise.

1373 (mono_debug_open_assembly_dwarf2_plus): Open the symbol file here.
1374 (mono_debug_close_assembly_dwarf2_plus): Close the symbol file here.
1375 (mono_debug_write_assembly_dwarf2_plus): Only call

1391 removed everything which is already in MonoDebugMethodInfo.
1393 * debug.c (debug_generate_method_lines): Generate the MonoILOffsetInfo array.

1432 * debug.c (mono_debug_get_type): Recursively call this for all function members
1434 (mono_debug_add_method): Don't mangle function names, this must be done by the
1435 debugger backend if the debugging format needs mangled names.
1437 * debug-dwarf2.c: Improved support for classes, added member functions.
1439 2002-03-16 Martin Baulig <martin@gnome.org>
1441 * debug.c (mono_debug_get_type): Recursively call this for all members and
1442 parent classes of a class type.
1444 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1445 since GDB doesn't like Java very much.
1447 2002-03-16 Martin Baulig <martin@gnome.org>
1449 * debug-dwarf2.c: Added support for enums.
1451 2002-03-15 Martin Baulig <martin@gnome.org>

1472 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1474 (mono_debug_open_file): Added MonoDebugFormat argument.
1475 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1476 this function from GDB. It's now safe to call this function multiple times;
1477 it'll always write a complete debugging file.
1479 * debug.c: Splitted this file into a general part which remains in this file
1480 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1481 All public functions now call a corresponding format specific function.
1483 * debug.c: The following changes are private to debug.c:
1484 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1485 (record_line_number, debug_generate_method_lines): New private functions.
1486 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1487 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1488 mono_debug_open_assembly_dwarf2).
1489 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1490 now safe to call this function multiple times.
1491 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1492 returns an unique index for this type. It's used to ensure that we only write
1493 each class once to the debugging file.
1494 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1495 data structure, but don't directly write to the debugging file. This is done
1496 later from mono_debug_write_assembly().
1498 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1499 debugging output. Call mono_debug_close() on cleanup if necessary.
1501 2002-03-14 Martin Baulig <martin@gnome.org>
1503 * debug-private.h: New private header file.
1505 * debug-stabs.c: Added the stabs type generation stuff which was
1506 previously in debug.c.
1508 * debug-dwarf.c: Started to implement type support. We're currently
1509 only writing this most basic types to the dwarf file, but this will
1512 2002-03-13 Martin Baulig <martin@gnome.org>
1514 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1515 debugging code. They're now in CVS, but not yet used anywhere.
1517 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1519 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1520 macros, included new delegate code from Daniel Stodden.
1523 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1525 * jit.c: verify that corlib and runtime are in sync.
1527 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1529 * emit-x86.c, jit.c: use the debug-helpers facilities to
1530 describe and match a method when debugging.
1532 2002-03-10 Martin Baulig <martin@gnome.org>
1534 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1535 output, put a nop instruction at the start of all functions so that
1536 the adresses won't change when using --debug.
1538 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1539 the bytecode area, stabs needs a line number in the .il file. Use the
1540 new info->moffsets to get the line number.
1541 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1542 `moffsets' is an array of `total_lines' fields (total number of lines
1543 in the .il file); for each line in the .il field, this array contains
1544 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1545 of a method and 0 otherwise.
1546 (debug_load_method_lines): Read the whole .il file and initialize the
1547 info->moffsets field.
1549 2002-03-09 Martin Baulig <martin@gnome.org>
1551 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1552 the unnecessary CDQ instruction.
1554 2002-03-07 Dietmar Maurer <dietmar@ximian.com>

1557 on the runtime stack.
1559 2002-03-07 Duncan Mak <duncan@ximian.com>
