285 2002-05-21 Martin Baulig <martin@gnome.org>
287 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
288 file for all assemblies. Currently, the JIT doesn't put all methods
289 from a single assembly into a continuous region of memory. We were
290 previously creating valid DWARF 2 files for this, but unfortunately
291 GDB's symbol tables get messed up when it reads more than one such file.
293 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

389 * exception.c (arch_handle_exception): EIP now points to the call
390 instruction, not to the instruction after the call. This fixes the

675 we need to pass the MonoMethod pointer as first argument.
677 * delegate.c (mono_async_invoke): notify all listeners, not only a

747 (mono_debug_open_assembly): When using MONO_DEBUG_FORMAT_DWARF2_PLUS, fall back
748 to MONO_DEBUG_FORMAT_DWARF2 if the symbol file does not exist, but the IL file
750 (debug_generate_method_lines): Generate correct IL offsets.
752 2002-03-28 Martin Baulig <martin@gnome.org>

761 * debug.c (debug_generate_method_lines): Don't return if we don't have line
762 numbers, we still need to generate the IL offsets here. Emit line numbers
763 for `prologue_end_offset' (the first line of actual code) and
764 `epilogue_begin_offset' (the line of the method's closing brace).
765 Don't crash if cfg->bblocks [i].forest is NULL.
766 (mono_debug_add_method): Don't crash if we don't have line numbers.
767 Initialize the newly added fields.
769 * debug-stabs.c: Record first and last line, emit filename info at the
770 beginning of the stab file, gdb ignores the types otherwise.
772 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
773 emit line number info for the first and last line.
775 2002-03-28 Dietmar Maurer <dietmar@ximian.com>
777 * invoke.c (arch_create_delegate_trampoline): impl.
779 Thu Mar 28 11:58:53 CET 2002 Paolo Molaro <lupus@ximian.com>
781 * Makefile.am, mono.c, jit.h, jit.c: build the libmono library
782 with the jit runtime to easy embedding. main() is moved to mono.c, now.

784 * debug.h, debug.c: constify char* argument.
786 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

805 lines if we don't have line number information.
806 (write_method_dwarf2): Use `minfo->method_info.this_offset' instead
809 * debug-stabs.c (write_method_stabs): Don't generate method lines if
810 we don't have line number information. Use `minfo->method_info.this_offset'
811 instead of hardcoding 8.
813 * debug.c (debug_generate_method_lines): Don't crash if we don't have
814 line number information.

816 MONO_DEBUG_FORMAT_DWARF2_PLUS.
817 (mono_debug_add_method): Don't store the 'this' offset in `param_offsets',
818 but it in the new `this_offset' field.
820 Mon Mar 25 13:03:35 CET 2002 Paolo Molaro <lupus@ximian.com>
822 * debug.c (debug_generate_method_lines): Use correct addresses for

834 2002-03-24 Martin Baulig <martin@gnome.org>
836 * debug.c (mono_debug_add_method): Include the `this' offset in
837 the `minfo->method_info.param_offsets' array.
839 2002-03-23 Martin Baulig <martin@gnome.org>
841 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
842 to do it before the X86_CMP.
843 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
844 (reg: CLT (lreg, lreg)): Likewise.

874 * debug-private.h (DebugMethodInfo): Added `MonoDebugMethodInfo method_info',
875 removed everything which is already in MonoDebugMethodInfo.
877 * debug.c (debug_generate_method_lines): Generate the MonoILOffsetInfo array.

916 * debug.c (mono_debug_get_type): Recursively call this for all function members
918 (mono_debug_add_method): Don't mangle function names, this must be done by the
919 debugger backend if the debugging format needs mangled names.
921 * debug-dwarf2.c: Improved support for classes, added member functions.
923 2002-03-16 Martin Baulig <martin@gnome.org>
925 * debug.c (mono_debug_get_type): Recursively call this for all members and
926 parent classes of a class type.
928 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
929 since GDB doesn't like Java very much.
931 2002-03-16 Martin Baulig <martin@gnome.org>
933 * debug-dwarf2.c: Added support for enums.
935 2002-03-15 Martin Baulig <martin@gnome.org>

956 * debug.c (MonoDebugFormat): New public enums specifying which debugging
958 (mono_debug_open_file): Added MonoDebugFormat argument.
959 (mono_debug_make_symbols): Don't take an argument to make it easier to call
960 this function from GDB. It's now safe to call this function multiple times;
961 it'll always write a complete debugging file.
963 * debug.c: Splitted this file into a general part which remains in this file
964 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
965 All public functions now call a corresponding format specific function.
967 * debug.c: The following changes are private to debug.c:
968 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
969 (record_line_number, debug_generate_method_lines): New private functions.
970 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
971 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
972 mono_debug_open_assembly_dwarf2).
973 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
974 now safe to call this function multiple times.
975 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
976 returns an unique index for this type. It's used to ensure that we only write
977 each class once to the debugging file.
978 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
979 data structure, but don't directly write to the debugging file. This is done
980 later from mono_debug_write_assembly().
982 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
983 debugging output. Call mono_debug_close() on cleanup if necessary.
985 2002-03-14 Martin Baulig <martin@gnome.org>
987 * debug-private.h: New private header file.
989 * debug-stabs.c: Added the stabs type generation stuff which was
990 previously in debug.c.

993 only writing this most basic types to the dwarf file, but this will
996 2002-03-13 Martin Baulig <martin@gnome.org>
998 * debug-stabs.c, debug-dwarf2.c: New files containing my new
999 debugging code. They're now in CVS, but not yet used anywhere.
1001 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1003 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1004 macros, included new delegate code from Daniel Stodden.

1009 * jit.c: verify that corlib and runtime are in sync.
1011 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1013 * emit-x86.c, jit.c: use the debug-helpers facilities to
1014 describe and match a method when debugging.
1016 2002-03-10 Martin Baulig <martin@gnome.org>
1018 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1019 output, put a nop instruction at the start of all functions so that
1020 the adresses won't change when using --debug.
1022 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1023 the bytecode area, stabs needs a line number in the .il file. Use the
1024 new info->moffsets to get the line number.
1025 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1026 `moffsets' is an array of `total_lines' fields (total number of lines
1027 in the .il file); for each line in the .il field, this array contains
1028 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1029 of a method and 0 otherwise.
1030 (debug_load_method_lines): Read the whole .il file and initialize the
1031 info->moffsets field.
1033 2002-03-09 Martin Baulig <martin@gnome.org>
1035 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1036 the unnecessary CDQ instruction.
1038 2002-03-07 Dietmar Maurer <dietmar@ximian.com>

1041 on the runtime stack.
1043 2002-03-07 Duncan Mak <duncan@ximian.com>

1110 Tue Feb 26 11:56:03 CET 2002 Paolo Molaro <lupus@ximian.com>
1112 * x86.brg: optimize cmp reg,0 -> test reg.

1116 * jit.h, jit.c, emit-x86.c: Added a few statistics counters
1117 and the --stats command line option to print them.
