3 * x86.brg (stmt): POP floating point stack correctly
5 2002-11-28 Dietmar Maurer <dietmar@ximian.com>
7 * emit-x86.c (arch_emit_prologue): don't save caller saved
10 * exception.c (x86_unwind_native_frame): support exceptions inside
11 native code using gcc generated exception tables (-fexception).
13 2002-11-19 Dietmar Maurer <dietmar@ximian.com>
15 * exception.c: include some code from Zoltan Varga, but modified
18 2002-11-27 Dietmar Maurer <dietmar@ximian.com>
20 * exception.c: massive code cleanups. The code is still
21 architecture dependent, but it should be now possible to reuse the
22 complex parts for other architecture.
24 2002-11-15 Dick Porter <dick@ximian.com>
26 * jit.c: Pass the attach callback to mono_runtime_init().
28 2002-11-12 Gonzalo Paniagua Javier <gonzalo@ximian.com>
30 * jit.c: display the domain name in trace output.
32 2002-11-08 Dietmar Maurer <dietmar@ximian.com>
34 * x86.brg (reg): fix bug #2721
36 * jit.c (mono_runtime_install_handlers): impl.
38 2002-10-17 Martin Baulig <martin@gnome.org>
40 * debug.c (mono_debug_add_method): Make this actually work if we don't
41 have any lifetime information.
43 2002-10-15 Martin Baulig <martin@gnome.org>
45 * jit.cs (PUSH_TREE): Always set t->cli_addr here.
47 * debug.c (generate_line_number): Small fix to make this actually
48 work for more complex things.
50 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
52 * x86.brg (freg): use fprem instead of fprem1
54 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
56 * jit.c (ves_array_element_address): added check for out of range index
57 (mono_analyze_stack): added fix for bug #31654
59 2002-10-01 Martin Baulig <martin@gnome.org>
61 * debug.c: Don't create an .il file for the dynamic symbol file.
63 2002-10-01 Martin Baulig <martin@gnome.org>

67 2002-09-27 Martin Baulig <martin@gnome.org>
69 * debug.c (debug_load_method_lines): Don't use sigaction() on win32.
71 2002-09-27 Dick Porter <dick@ximian.com>
73 * mono.c: Tell glib what the program name is, by passing it the
74 name of the managed file we're executing
76 2002-09-26 Martin Baulig <martin@gnome.org>
78 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
79 trampoline into the vtable, also use it for non-virtual methods,
80 remove the breakpoint when done.
82 2002-09-26 Martin Baulig <martin@gnome.org>
84 * debug.c (debug_load_method_lines): Block SIGCHLD while running
87 2002-09-26 Martin Baulig <martin@gnome.org>
89 * debug.c: Reworked the whole debugging stuff. We have now one
90 single `mono_debug_handle' which keeps a hashtable of
91 `AssemblyDebugInfo's (which may have different debugging formats).
92 The AssemblyDebugInfo is now created when the assembly is loaded,
93 but never when adding a class/type.
95 * mono.c: Initialize debugging stuff after corlib and the assembly
98 2002-09-25 Martin Baulig <martin@gnome.org>
100 * debug-private.h (DebugLineNumberInfo): Removed. There's now a
101 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
103 (DebugMethodInfo): Removed `line_numbers'.
105 * debug.c: Reworked the line number generation; we're now using
106 the MonoDebugLineNumberEntry try for all debugging formats. This
107 type also includes the line number and IL offset, this allows the
108 JIT to produce better line number info: we only emit line number
109 information for source lines which actually have code.
111 2002-09-25 Martin Baulig <martin@gnome.org>
113 * debug.h: Removed external declaration of all functions which
114 should only be called from the Mono Debugger and also made them
115 static. Since the debugger gets their address from the
116 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
119 2002-09-25 Martin Baulig <martin@gnome.org>
121 Improved breakpoint support, we can now dynamically insert and
122 remove breakpoints at runtime and when called from withing the
123 Mono Debugger, we're using a special breakpoint trampoline.

126 whether to insert a breakpoint for a method.
127 (mono_insert_breakpoint): New method to insert a breakpoint.
128 (mono_insert_breakpoint_full): New method to insert a breakpoint,
129 takes a MonoMethodDesc.
130 (mono_remove_breakpoint): New method to remove a breakpoint.
132 * debug.c (mono_debugger_insert_breakpoint): New function for the
133 debugger. Should only be called from the debugger.
134 (mono_debugger_remove_breakpoint): Likewise.
136 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
138 * trampoline.c (get_breakpoint_trampoline): New static function to
139 create a special breakpoint trampoline for the debugger.
140 (x86_magic_trampoline): If we're running inside the Mono Debugger
141 and a breakpoint was requested for the method, generate a special
142 breakpoint trampoline.
144 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
145 to insert a breakpoint.
146 (mono_debug_last_breakpoint_address): Removed.
147 (match_debug_method): Removed, use mono_method_has_breakpoint().
149 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
151 * jit.c: reorder mono_runtime_cleanup () call since it needs the
152 engine still fully working.
154 2002-09-24 Martin Baulig <martin@gnome.org>
156 * debug.c (mono_debug_open): When we're invoked from inside the
157 Mono Debugger, set mono_debugger_class_init_func (exported in
158 metadata/class.c) to mono_add_type().
159 (mono_add_type): Call mono_debug_symfile_add_type().
161 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
163 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
164 Run finalize on domain cleanup.
165 * mono.c: call setlocale ().
166 * trampoline.c: clearer error message for invalid trampoline.
168 2002-09-21 Martin Baulig <martin@gnome.org>
170 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
171 instead of writing a byte blob.
172 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
173 (mono_debug_add_method): Incrementally add the new method to the symbol
176 * exception.c (arch_handle_exception): If we have debugging support,
177 call mono_debugger_update_symbol_file_table () as well.
179 2002-09-20 Martin Baulig <martin@gnome.org>
181 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
182 the size of the variable.
184 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
186 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
187 iterations if we visit blocks in reverse order.
189 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
191 * jit.c (mono_analyze_stack): cleaup of the array code
193 * exception.c: added patch from Julio Merno to fix bug #30048

197 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
199 * x86.brg (LDELEMA): use x86_lea
201 2002-09-06 Martin Baulig <martin@gnome.org>
203 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
204 If you were getting random crashes when using the JIT with debugging
205 turned on, this fixes it.
207 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
209 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
211 2002-09-05 Martin Baulig <martin@gnome.org>
213 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
214 which is read by the debugger.
216 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>

228 * debug-dwarf2-plus.c: Removed.
230 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
231 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
232 `mono_symfile' to `symfile'.
234 * debug.c (mono_debug_open): Replaced the assembly argument with a
235 file name argument; you can now call this before loading the assembly.
236 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
237 we now use MonoSymbolFileLineNumberEntry's and a separate address array
238 instead; splitted out all MonoSymbolFileLineNumberEntry code into
239 debug_generate_il_offsets() and debug_update_il_offsets().
240 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
241 created when reading the symbol file or from debug_load_method_lines().
242 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
244 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before

268 * mono.c: don't use the cil-coff header outside of the loader.
270 2002-08-27 Martin Baulig <martin@gnome.org>
272 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need

282 (arch_create_jit_trampoline): Use the new global variable to store the
283 generic trampoline code instead of using a static one. This allows the
284 debugger to access this variable to check whether a method is a trampoline.
286 * debug.h (mono_generic_trampoline_code): Added external declaration.
288 2002-08-27 Martin Baulig <martin@gnome.org>
290 * debug.c (MonoDebugHandle): Moved the method hash into the
291 AssemblyDebugInfo struct since we need to use a separate hash for each
294 * debug.c: Added special undocumented command line argument to create a
295 symbol file for IL files on-the-fly. In this case, we also need to create
296 the IL files and parse them.

398 than one page, it's necessary to allocate memory incrementally,
399 in page-size steps, performing stack-touch every time.

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

818 2002-05-21 Martin Baulig <martin@gnome.org>
820 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
821 file for all assemblies. Currently, the JIT doesn't put all methods
822 from a single assembly into a continuous region of memory. We were
823 previously creating valid DWARF 2 files for this, but unfortunately
824 GDB's symbol tables get messed up when it reads more than one such file.
826 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

1208 we need to pass the MonoMethod pointer as first argument.
1210 * delegate.c (mono_async_invoke): notify all listeners, not only a
1212 (arch_end_invoke): we now pass a MonoMethod as first parameter and
1213 use arch_method_call_message_new() to access the stack.
1214 (arch_end_invoke): wait until we really finished processing
1215 (async_invoke_abort): notify all listeners, not only a
1218 2002-04-06 Dietmar Maurer <dietmar@ximian.com>

1294 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1295 numbers, we still need to generate the IL offsets here. Emit line numbers
1296 for `prologue_end_offset' (the first line of actual code) and
1297 `epilogue_begin_offset' (the line of the method's closing brace).
1298 Don't crash if cfg->bblocks [i].forest is NULL.
1299 (mono_debug_add_method): Don't crash if we don't have line numbers.
1300 Initialize the newly added fields.
1302 * debug-stabs.c: Record first and last line, emit filename info at the
1303 beginning of the stab file, gdb ignores the types otherwise.
1305 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1306 emit line number info for the first and last line.
1308 2002-03-28 Dietmar Maurer <dietmar@ximian.com>
1310 * invoke.c (arch_create_delegate_trampoline): impl.

1317 * debug.h, debug.c: constify char* argument.
1319 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

1339 (write_method_dwarf2): Use `minfo->method_info.this_offset' instead
1342 * debug-stabs.c (write_method_stabs): Don't generate method lines if
1343 we don't have line number information. Use `minfo->method_info.this_offset'
1344 instead of hardcoding 8.
1346 * debug.c (debug_generate_method_lines): Don't crash if we don't have
1347 line number information.

1363 2002-03-25 Martin Baulig <martin@gnome.org>
1365 * debug.h (mono_debug_make_symbols): Documented this function.
1367 2002-03-24 Martin Baulig <martin@gnome.org>
1369 * debug.c (mono_debug_add_method): Include the `this' offset in
1370 the `minfo->method_info.param_offsets' array.
1372 2002-03-23 Martin Baulig <martin@gnome.org>
1374 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1375 to do it before the X86_CMP.
1376 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1377 (reg: CLT (lreg, lreg)): Likewise.

1449 * debug.c (mono_debug_get_type): Recursively call this for all function members
1451 (mono_debug_add_method): Don't mangle function names, this must be done by the
1452 debugger backend if the debugging format needs mangled names.
1454 * debug-dwarf2.c: Improved support for classes, added member functions.
1456 2002-03-16 Martin Baulig <martin@gnome.org>
1458 * debug.c (mono_debug_get_type): Recursively call this for all members and
1459 parent classes of a class type.
1461 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1462 since GDB doesn't like Java very much.
1464 2002-03-16 Martin Baulig <martin@gnome.org>
1466 * debug-dwarf2.c: Added support for enums.
1468 2002-03-15 Martin Baulig <martin@gnome.org>

1489 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1491 (mono_debug_open_file): Added MonoDebugFormat argument.
1492 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1493 this function from GDB. It's now safe to call this function multiple times;
1494 it'll always write a complete debugging file.
1496 * debug.c: Splitted this file into a general part which remains in this file
1497 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1498 All public functions now call a corresponding format specific function.
1500 * debug.c: The following changes are private to debug.c:
1501 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1502 (record_line_number, debug_generate_method_lines): New private functions.
1503 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1504 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1505 mono_debug_open_assembly_dwarf2).
1506 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1507 now safe to call this function multiple times.
1508 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1509 returns an unique index for this type. It's used to ensure that we only write
1510 each class once to the debugging file.
1511 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1512 data structure, but don't directly write to the debugging file. This is done
1513 later from mono_debug_write_assembly().
1515 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1516 debugging output. Call mono_debug_close() on cleanup if necessary.
1518 2002-03-14 Martin Baulig <martin@gnome.org>
1520 * debug-private.h: New private header file.
1522 * debug-stabs.c: Added the stabs type generation stuff which was
1523 previously in debug.c.
1525 * debug-dwarf.c: Started to implement type support. We're currently
1526 only writing this most basic types to the dwarf file, but this will
1529 2002-03-13 Martin Baulig <martin@gnome.org>
1531 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1532 debugging code. They're now in CVS, but not yet used anywhere.
1534 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1536 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1537 macros, included new delegate code from Daniel Stodden.
1540 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1542 * jit.c: verify that corlib and runtime are in sync.
1544 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1546 * emit-x86.c, jit.c: use the debug-helpers facilities to
1547 describe and match a method when debugging.
1549 2002-03-10 Martin Baulig <martin@gnome.org>
1551 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1552 output, put a nop instruction at the start of all functions so that
1553 the adresses won't change when using --debug.
1555 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1556 the bytecode area, stabs needs a line number in the .il file. Use the
1557 new info->moffsets to get the line number.
1558 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1559 `moffsets' is an array of `total_lines' fields (total number of lines
1560 in the .il file); for each line in the .il field, this array contains
1561 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1562 of a method and 0 otherwise.
1563 (debug_load_method_lines): Read the whole .il file and initialize the
1564 info->moffsets field.
1566 2002-03-09 Martin Baulig <martin@gnome.org>
1568 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1569 the unnecessary CDQ instruction.
1571 2002-03-07 Dietmar Maurer <dietmar@ximian.com>

1574 on the runtime stack.
1576 2002-03-07 Duncan Mak <duncan@ximian.com>
