3 * debug.c: The mono symbol file is installed together with the assembly
4 it belongs to and it's used on a per-image basis.
6 Tue Aug 27 19:44:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
8 * mono.c: don't use the cil-coff header outside of the loader.
10 2002-08-27 Martin Baulig <martin@gnome.org>
12 * debug.c (mono_debugger_internal_get_symbol_files): Removed, we need
13 to use global variables for this since they're stored in a core file.

28 2002-08-27 Martin Baulig <martin@gnome.org>
30 * debug.c (MonoDebugHandle): Moved the method hash into the
31 AssemblyDebugInfo struct since we need to use a separate hash for each
34 * debug.c: Added special undocumented command line argument to create a
35 symbol file for IL files on-the-fly. In this case, we also need to create
36 the IL files and parse them.

79 2002-08-19 Nick Drochak <ndrochak@gol.com>
81 * x86.brg (mono_llmult_ovf): Simplified the code greatly by refactoring
82 the algebraic form we are using. This also eliminated a silly overflow
83 of the intermediate result that was causing troubles.
85 2002-08-16 Nick Drochak <ndrochak@gol.com>
87 * x86.brg (mono_llmult_ovf): Flip ALL the bits, dummy. Now negative numbers
90 2002-08-15 Nick Drochak <ndrochak@gol.com>
92 * x86.brg (mono_llmult_ovf): Fix so it throws an overflow when result
93 will not fit in 64 bits. Fixes bug #27375.

108 2002-08-08 Dietmar Maurer <dietmar@ximian.com>

111 libpthread/kernel restore the context. This should work on recent
112 versions of linuxthreads.
114 * jit.c (mono_runtime_install_handlers): switch back to use
115 sigaction from libpthreads. As long as this does not make problems
116 we should use this instead of syscall.

138 than one page, it's necessary to allocate memory incrementally,
139 in page-size steps, performing stack-touch every time.
140 Also added LOCALLOC(CONST_I4) implementation.
142 2002-07-27 Dietmar Maurer <dietmar@ximian.com>

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

468 * debug-dwarf2.c (dwarf2_write_section_end): Removed. This is not needed
469 and not supported by all assemblers.

477 * debug.c: Added "dont_assemble" and "dont_precompile" argument for dwarf-plus.

516 a `MonoAssembly *' argument instead of a `char *filename' one. Also added
517 `const char **args' argument.
519 * mono.c (mono_jit_assembly): Renamed to mono_jit_compile_image(), added
520 `int verbose' argument and made it public.
521 (mono_jit_compile_class): New public function, moved the code to compile
522 all methods in a class here from main().
523 (--compile): The argument can now also be an image (in `@imagename' format).
524 Updated documentation for this command line argument.
525 (--precompile): New command line argument to precompile an image/class/method

534 * debug-dwarf2-plus.c (mono_debug_open_assembly_dwarf2_plus): Use the new

538 2002-05-21 Martin Baulig <martin@gnome.org>
540 * debug-dwarf2-plus.c: This is now working again :-)
542 * debug.c (mono_debug_open_file): When using MONO_DEBUG_FORMAT_DWARF2_PLUS,

558 2002-05-21 Martin Baulig <martin@gnome.org>
560 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
561 file for all assemblies. Currently, the JIT doesn't put all methods
562 from a single assembly into a continuous region of memory. We were
563 previously creating valid DWARF 2 files for this, but unfortunately
564 GDB's symbol tables get messed up when it reads more than one such file.
566 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

581 (mono_debug_open_assembly_stabs): Removed.
582 (mono_debug_close_assembly_stabs).
584 * debug-dwarf2-plus.c: This is currently broken. :-(
586 2002-05-20 Martin Baulig <martin@gnome.org>
588 * debug.h (mono_debug_format): New global variable.
589 (MonoDebugFormat): Added MONO_DEBUG_FORMAT_NONE.

1185 * debug-dwarf2.c: Added support for strings and arrays.
1187 2002-03-17 Martin Baulig <martin@gnome.org>
1189 * debug.c (mono_debug_get_type): Recursively call this for all function members
1191 (mono_debug_add_method): Don't mangle function names, this must be done by the
1192 debugger backend if the debugging format needs mangled names.
1194 * debug-dwarf2.c: Improved support for classes, added member functions.
1196 2002-03-16 Martin Baulig <martin@gnome.org>
1198 * debug.c (mono_debug_get_type): Recursively call this for all members and
1199 parent classes of a class type.
1201 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
1202 since GDB doesn't like Java very much.
1204 2002-03-16 Martin Baulig <martin@gnome.org>
1206 * debug-dwarf2.c: Added support for enums.
1208 2002-03-15 Martin Baulig <martin@gnome.org>

1229 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1231 (mono_debug_open_file): Added MonoDebugFormat argument.
1232 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1233 this function from GDB. It's now safe to call this function multiple times;
1234 it'll always write a complete debugging file.
1236 * debug.c: Splitted this file into a general part which remains in this file
1237 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1238 All public functions now call a corresponding format specific function.
1240 * debug.c: The following changes are private to debug.c:
1241 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1242 (record_line_number, debug_generate_method_lines): New private functions.
1243 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1244 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1245 mono_debug_open_assembly_dwarf2).
1246 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1247 now safe to call this function multiple times.
1248 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1249 returns an unique index for this type. It's used to ensure that we only write
1250 each class once to the debugging file.
1251 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1252 data structure, but don't directly write to the debugging file. This is done
1253 later from mono_debug_write_assembly().
1255 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1256 debugging output. Call mono_debug_close() on cleanup if necessary.
1258 2002-03-14 Martin Baulig <martin@gnome.org>
1260 * debug-private.h: New private header file.
1262 * debug-stabs.c: Added the stabs type generation stuff which was
1263 previously in debug.c.
1265 * debug-dwarf.c: Started to implement type support. We're currently
1266 only writing this most basic types to the dwarf file, but this will
1269 2002-03-13 Martin Baulig <martin@gnome.org>
1271 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1272 debugging code. They're now in CVS, but not yet used anywhere.
1274 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1276 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1277 macros, included new delegate code from Daniel Stodden.

1282 * jit.c: verify that corlib and runtime are in sync.
1284 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1286 * emit-x86.c, jit.c: use the debug-helpers facilities to
1287 describe and match a method when debugging.
1289 2002-03-10 Martin Baulig <martin@gnome.org>
1291 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1292 output, put a nop instruction at the start of all functions so that
1293 the adresses won't change when using --debug.
1295 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1296 the bytecode area, stabs needs a line number in the .il file. Use the
1297 new info->moffsets to get the line number.
1298 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1299 `moffsets' is an array of `total_lines' fields (total number of lines
1300 in the .il file); for each line in the .il field, this array contains
1301 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1302 of a method and 0 otherwise.
1303 (debug_load_method_lines): Read the whole .il file and initialize the
1304 info->moffsets field.
1306 2002-03-09 Martin Baulig <martin@gnome.org>
1308 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1309 the unnecessary CDQ instruction.
1311 2002-03-07 Dietmar Maurer <dietmar@ximian.com>

1314 on the runtime stack.
