6 work for more complex things.
8 2002-10-11 Dietmar Maurer <dietmar@ximian.com>
10 * x86.brg (freg): use fprem instead of fprem1
12 2002-10-03 Dietmar Maurer <dietmar@ximian.com>
14 * jit.c (ves_array_element_address): added check for out of range index
15 (mono_analyze_stack): added fix for bug #31654
17 2002-10-01 Martin Baulig <martin@gnome.org>
19 * debug.c: Don't create an .il file for the dynamic symbol file.
21 2002-10-01 Martin Baulig <martin@gnome.org>

32 name of the managed file we're executing
34 2002-09-26 Martin Baulig <martin@gnome.org>
36 * trampoline.c (x86_magic_trampoline): Don't insert the breakpoint
37 trampoline into the vtable, also use it for non-virtual methods,
38 remove the breakpoint when done.
40 2002-09-26 Martin Baulig <martin@gnome.org>
42 * debug.c (debug_load_method_lines): Block SIGCHLD while running
45 2002-09-26 Martin Baulig <martin@gnome.org>
47 * debug.c: Reworked the whole debugging stuff. We have now one
48 single `mono_debug_handle' which keeps a hashtable of
49 `AssemblyDebugInfo's (which may have different debugging formats).
50 The AssemblyDebugInfo is now created when the assembly is loaded,
51 but never when adding a class/type.
53 * mono.c: Initialize debugging stuff after corlib and the assembly
56 2002-09-25 Martin Baulig <martin@gnome.org>

59 MonoDebugLineNumberEntry type in debug-mono-symfile.h which we're
61 (DebugMethodInfo): Removed `line_numbers'.
63 * debug.c: Reworked the line number generation; we're now using
64 the MonoDebugLineNumberEntry try for all debugging formats. This
65 type also includes the line number and IL offset, this allows the
66 JIT to produce better line number info: we only emit line number
67 information for source lines which actually have code.
69 2002-09-25 Martin Baulig <martin@gnome.org>
71 * debug.h: Removed external declaration of all functions which
72 should only be called from the Mono Debugger and also made them
73 static. Since the debugger gets their address from the
74 `MONO_DEBUGGER__debugger_info' vtable, there's no need to export
77 2002-09-25 Martin Baulig <martin@gnome.org>
79 Improved breakpoint support, we can now dynamically insert and
80 remove breakpoints at runtime and when called from withing the
81 Mono Debugger, we're using a special breakpoint trampoline.

84 whether to insert a breakpoint for a method.
85 (mono_insert_breakpoint): New method to insert a breakpoint.
86 (mono_insert_breakpoint_full): New method to insert a breakpoint,
87 takes a MonoMethodDesc.
88 (mono_remove_breakpoint): New method to remove a breakpoint.
90 * debug.c (mono_debugger_insert_breakpoint): New function for the
91 debugger. Should only be called from the debugger.
92 (mono_debugger_remove_breakpoint): Likewise.
94 * mono.c (main): Use mono_insert_breakpoint() to insert breakpoints.
96 * trampoline.c (get_breakpoint_trampoline): New static function to
97 create a special breakpoint trampoline for the debugger.
98 (x86_magic_trampoline): If we're running inside the Mono Debugger
99 and a breakpoint was requested for the method, generate a special
100 breakpoint trampoline.
102 * jit.c (mono_debug_methods): Removed, use mono_insert_breakpoint()
103 to insert a breakpoint.
104 (mono_debug_last_breakpoint_address): Removed.
105 (match_debug_method): Removed, use mono_method_has_breakpoint().
107 Wed Sep 25 12:04:08 CEST 2002 Paolo Molaro <lupus@ximian.com>
109 * jit.c: reorder mono_runtime_cleanup () call since it needs the
110 engine still fully working.
112 2002-09-24 Martin Baulig <martin@gnome.org>
114 * debug.c (mono_debug_open): When we're invoked from inside the
115 Mono Debugger, set mono_debugger_class_init_func (exported in
116 metadata/class.c) to mono_add_type().
117 (mono_add_type): Call mono_debug_symfile_add_type().
119 Tue Sep 24 11:34:02 CEST 2002 Paolo Molaro <lupus@ximian.com>
121 * jit.c: avoid including cil-coff.h (again). Optimize typeof (type).
122 Run finalize on domain cleanup.
123 * mono.c: call setlocale ().
124 * trampoline.c: clearer error message for invalid trampoline.
126 2002-09-21 Martin Baulig <martin@gnome.org>
128 * debug.c (MonoDebuggerSymbolFileTable): Use an actual typedef for this
129 instead of writing a byte blob.
130 (mono_debug_make_symbols): This doesn't touch the symbol tables anymore.
131 (mono_debug_add_method): Incrementally add the new method to the symbol
134 * exception.c (arch_handle_exception): If we have debugging support,
135 call mono_debugger_update_symbol_file_table () as well.
137 2002-09-20 Martin Baulig <martin@gnome.org>
139 * debug.c (mono_debug_add_method): The `MonoDebugVarInfo' now includes
140 the size of the variable.
142 2002-09-18 Dietmar Maurer <dietmar@ximian.com>
144 * linear-scan.c (mono_analyze_liveness): we can save 30% of needed
145 iterations if we visit blocks in reverse order.
147 2002-09-12 Dietmar Maurer <dietmar@ximian.com>
149 * jit.c (mono_analyze_stack): cleaup of the array code
151 * exception.c: added patch from Julio Merno to fix bug #30048

155 2002-09-09 Dietmar Maurer <dietmar@ximian.com>
157 * x86.brg (LDELEMA): use x86_lea
159 2002-09-06 Martin Baulig <martin@gnome.org>
161 * debug.c (debug_update_il_offsets): Fixed a memory corruption bug.
162 If you were getting random crashes when using the JIT with debugging
163 turned on, this fixes it.
165 2002-09-06 Dietmar Maurer <dietmar@ximian.com>
167 * emit-x86.c (arch_emit_epilogue): use pop instead of mov
169 2002-09-05 Martin Baulig <martin@gnome.org>
171 * debug.c (MONO_DEBUGGER__debugger_info): New global data symbol
172 which is read by the debugger.
174 Wed Sep 4 14:06:09 CEST 2002 Paolo Molaro <lupus@ximian.com>

188 * debug-private.h (DebugMethodInfo): Removed the `method_info' field.
189 (AssemblyDebugInfo): Removed the old `symfile' field and renamed
190 `mono_symfile' to `symfile'.
192 * debug.c (mono_debug_open): Replaced the assembly argument with a
193 file name argument; you can now call this before loading the assembly.
194 (debug_generate_method_lines): The MonoDebugILOffsetInfo struct is gone,
195 we now use MonoSymbolFileLineNumberEntry's and a separate address array
196 instead; splitted out all MonoSymbolFileLineNumberEntry code into
197 debug_generate_il_offsets() and debug_update_il_offsets().
198 (mono_debug_add_method): Don't create the MonoDebugMethodInfo here; it's
199 created when reading the symbol file or from debug_load_method_lines().
200 (debug_load_method_lines): Create the MonoDebugMethodInfo for all methods.
202 * exception.c (arch_handle_exception): Call mono_debug_make_symbols() before

228 2002-08-27 Martin Baulig <martin@gnome.org>
230 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need

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

623 2002-05-24 Dietmar Maurer <dietmar@ximian.com>
625 * x86.brg (stmt): use memmove to cope with overlapping
626 blocks. This is not required by the specs, so we can remove it
627 later if it turns out to be too slow (and use memcpy).

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

684 2002-05-22 Martin Baulig <martin@gnome.org>
686 * debug-dwarf2.c (dwarf2_write_section_end): Removed. This is not needed
687 and not supported by all assemblers.

691 * mono.c (--debug): Small fix in the argument parsing.
693 2002-05-22 Martin Baulig <martin@gnome.org>
695 * debug.c: Added "dont_assemble" and "dont_precompile" argument for dwarf-plus.
697 * mono.c: Applied patch from Miguel:

734 a `MonoAssembly *' argument instead of a `char *filename' one. Also added
735 `const char **args' argument.
737 * mono.c (mono_jit_assembly): Renamed to mono_jit_compile_image(), added
738 `int verbose' argument and made it public.
739 (mono_jit_compile_class): New public function, moved the code to compile
740 all methods in a class here from main().

776 2002-05-21 Martin Baulig <martin@gnome.org>
778 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
779 file for all assemblies. Currently, the JIT doesn't put all methods
780 from a single assembly into a continuous region of memory. We were
781 previously creating valid DWARF 2 files for this, but unfortunately
782 GDB's symbol tables get messed up when it reads more than one such file.
784 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',
785 `next_idx', `methods', `type_hash', `source_files' and `format'
786 into the MonoDebugHandle.

1225 Set `mono_debug_last_breakpoint_address' to the address of the last inserted
1228 * debug.h: Provide external declaration of `mono_debug_insert_breakpoint' and
1229 `mono_debug_last_breakpoint_address', also documented them here.

1252 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1253 numbers, we still need to generate the IL offsets here. Emit line numbers
1254 for `prologue_end_offset' (the first line of actual code) and
1255 `epilogue_begin_offset' (the line of the method's closing brace).
1256 Don't crash if cfg->bblocks [i].forest is NULL.
1257 (mono_debug_add_method): Don't crash if we don't have line numbers.
1258 Initialize the newly added fields.
1260 * debug-stabs.c: Record first and last line, emit filename info at the

1263 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1264 emit line number info for the first and last line.
1266 2002-03-28 Dietmar Maurer <dietmar@ximian.com>
1268 * invoke.c (arch_create_delegate_trampoline): impl.

1300 * debug-stabs.c (write_method_stabs): Don't generate method lines if
1301 we don't have line number information. Use `minfo->method_info.this_offset'
1302 instead of hardcoding 8.

1325 2002-03-24 Martin Baulig <martin@gnome.org>
1327 * debug.c (mono_debug_add_method): Include the `this' offset in
1328 the `minfo->method_info.param_offsets' array.
1330 2002-03-23 Martin Baulig <martin@gnome.org>
1332 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1333 to do it before the X86_CMP.
1334 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1335 (reg: CLT (lreg, lreg)): Likewise.

1412 * debug-dwarf2.c: Improved support for classes, added member functions.
1414 2002-03-16 Martin Baulig <martin@gnome.org>
1416 * debug.c (mono_debug_get_type): Recursively call this for all members and
1417 parent classes of a class type.
1419 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1420 since GDB doesn't like Java very much.
1422 2002-03-16 Martin Baulig <martin@gnome.org>
1424 * debug-dwarf2.c: Added support for enums.
1426 2002-03-15 Martin Baulig <martin@gnome.org>

1447 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1449 (mono_debug_open_file): Added MonoDebugFormat argument.
1450 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1451 this function from GDB. It's now safe to call this function multiple times;
1452 it'll always write a complete debugging file.
1454 * debug.c: Splitted this file into a general part which remains in this file
1455 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1456 All public functions now call a corresponding format specific function.
1458 * debug.c: The following changes are private to debug.c:
1459 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1460 (record_line_number, debug_generate_method_lines): New private functions.
1461 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1462 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1463 mono_debug_open_assembly_dwarf2).
1464 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1465 now safe to call this function multiple times.
1466 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1467 returns an unique index for this type. It's used to ensure that we only write
1468 each class once to the debugging file.
1469 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1470 data structure, but don't directly write to the debugging file. This is done
1471 later from mono_debug_write_assembly().
1473 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1474 debugging output. Call mono_debug_close() on cleanup if necessary.
1476 2002-03-14 Martin Baulig <martin@gnome.org>
1478 * debug-private.h: New private header file.
1480 * debug-stabs.c: Added the stabs type generation stuff which was
1481 previously in debug.c.
1483 * debug-dwarf.c: Started to implement type support. We're currently
1484 only writing this most basic types to the dwarf file, but this will
1487 2002-03-13 Martin Baulig <martin@gnome.org>
1489 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1490 debugging code. They're now in CVS, but not yet used anywhere.
1492 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1494 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1495 macros, included new delegate code from Daniel Stodden.
1498 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1500 * jit.c: verify that corlib and runtime are in sync.
1502 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1504 * emit-x86.c, jit.c: use the debug-helpers facilities to
1505 describe and match a method when debugging.
1507 2002-03-10 Martin Baulig <martin@gnome.org>
1509 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1510 output, put a nop instruction at the start of all functions so that
1511 the adresses won't change when using --debug.
1513 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1514 the bytecode area, stabs needs a line number in the .il file. Use the
1515 new info->moffsets to get the line number.
1516 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1517 `moffsets' is an array of `total_lines' fields (total number of lines
1518 in the .il file); for each line in the .il field, this array contains
1519 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1520 of a method and 0 otherwise.
1521 (debug_load_method_lines): Read the whole .il file and initialize the
1522 info->moffsets field.
1524 2002-03-09 Martin Baulig <martin@gnome.org>
1526 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1527 the unnecessary CDQ instruction.
1529 2002-03-07 Dietmar Maurer <dietmar@ximian.com>

1532 on the runtime stack.
1534 2002-03-07 Duncan Mak <duncan@ximian.com>
