44 2002-09-24 Martin Baulig <martin@gnome.org>
46 * debug.c (mono_debug_open): When we're invoked from inside the
47 Mono Debugger, set mono_debugger_class_init_func (exported in

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

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

708 2002-05-21 Martin Baulig <martin@gnome.org>
710 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
711 file for all assemblies. Currently, the JIT doesn't put all methods
712 from a single assembly into a continuous region of memory. We were
713 previously creating valid DWARF 2 files for this, but unfortunately
714 GDB's symbol tables get messed up when it reads more than one such file.
716 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

1184 * debug.c (debug_generate_method_lines): Don't return if we don't have line
1185 numbers, we still need to generate the IL offsets here. Emit line numbers
1186 for `prologue_end_offset' (the first line of actual code) and
1187 `epilogue_begin_offset' (the line of the method's closing brace).
1188 Don't crash if cfg->bblocks [i].forest is NULL.
1189 (mono_debug_add_method): Don't crash if we don't have line numbers.
1190 Initialize the newly added fields.
1192 * debug-stabs.c: Record first and last line, emit filename info at the
1193 beginning of the stab file, gdb ignores the types otherwise.
1195 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
1196 emit line number info for the first and last line.

1262 2002-03-23 Martin Baulig <martin@gnome.org>
1264 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
1265 to do it before the X86_CMP.
1266 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
1267 (reg: CLT (lreg, lreg)): Likewise.

1379 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1381 (mono_debug_open_file): Added MonoDebugFormat argument.
1382 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1383 this function from GDB. It's now safe to call this function multiple times;
1384 it'll always write a complete debugging file.
1386 * debug.c: Splitted this file into a general part which remains in this file
1387 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1388 All public functions now call a corresponding format specific function.
1390 * debug.c: The following changes are private to debug.c:
1391 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1392 (record_line_number, debug_generate_method_lines): New private functions.
1393 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1394 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1395 mono_debug_open_assembly_dwarf2).
1396 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1397 now safe to call this function multiple times.
1398 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1399 returns an unique index for this type. It's used to ensure that we only write
1400 each class once to the debugging file.
1401 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1402 data structure, but don't directly write to the debugging file. This is done
1403 later from mono_debug_write_assembly().
1405 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1406 debugging output. Call mono_debug_close() on cleanup if necessary.
1408 2002-03-14 Martin Baulig <martin@gnome.org>
1410 * debug-private.h: New private header file.
1412 * debug-stabs.c: Added the stabs type generation stuff which was
1413 previously in debug.c.

1416 only writing this most basic types to the dwarf file, but this will
1419 2002-03-13 Martin Baulig <martin@gnome.org>
1421 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1422 debugging code. They're now in CVS, but not yet used anywhere.
1424 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1426 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*

1432 * jit.c: verify that corlib and runtime are in sync.
1434 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1436 * emit-x86.c, jit.c: use the debug-helpers facilities to
1437 describe and match a method when debugging.
1439 2002-03-10 Martin Baulig <martin@gnome.org>
1441 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1442 output, put a nop instruction at the start of all functions so that
1443 the adresses won't change when using --debug.
1445 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1446 the bytecode area, stabs needs a line number in the .il file. Use the
1447 new info->moffsets to get the line number.
1448 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1449 `moffsets' is an array of `total_lines' fields (total number of lines
1450 in the .il file); for each line in the .il field, this array contains
1451 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1452 of a method and 0 otherwise.
1453 (debug_load_method_lines): Read the whole .il file and initialize the
1454 info->moffsets field.
1456 2002-03-09 Martin Baulig <martin@gnome.org>
1458 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1459 the unnecessary CDQ instruction.
1461 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
