238 `int verbose' argument and made it public.

276 2002-05-21 Martin Baulig <martin@gnome.org>
278 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
279 file for all assemblies. Currently, the JIT doesn't put all methods
280 from a single assembly into a continuous region of memory. We were
281 previously creating valid DWARF 2 files for this, but unfortunately
282 GDB's symbol tables get messed up when it reads more than one such file.
284 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

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

596 * emit-x86.c, invoke.c: call profile callbacks if needed.
597 * jit.c, jit.h, mono.c: add --profile command line option.
599 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>

666 we need to pass the MonoMethod pointer as first argument.
668 * delegate.c (mono_async_invoke): notify all listeners, not only a
670 (arch_end_invoke): we now pass a MonoMethod as first parameter and
671 use arch_method_call_message_new() to access the stack.

738 (mono_debug_open_assembly): When using MONO_DEBUG_FORMAT_DWARF2_PLUS, fall back
739 to MONO_DEBUG_FORMAT_DWARF2 if the symbol file does not exist, but the IL file
741 (debug_generate_method_lines): Generate correct IL offsets.
743 2002-03-28 Martin Baulig <martin@gnome.org>

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

775 * debug.h, debug.c: constify char* argument.
777 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

796 lines if we don't have line number information.
797 (write_method_dwarf2): Use `minfo->method_info.this_offset' instead
800 * debug-stabs.c (write_method_stabs): Don't generate method lines if
801 we don't have line number information. Use `minfo->method_info.this_offset'
802 instead of hardcoding 8.
804 * debug.c (debug_generate_method_lines): Don't crash if we don't have
805 line number information.
806 (mono_debug_open_assembly): Don't generate line numbers for
807 MONO_DEBUG_FORMAT_DWARF2_PLUS.
808 (mono_debug_add_method): Don't store the 'this' offset in `param_offsets',
809 but it in the new `this_offset' field.
811 Mon Mar 25 13:03:35 CET 2002 Paolo Molaro <lupus@ximian.com>
813 * debug.c (debug_generate_method_lines): Use correct addresses for

825 2002-03-24 Martin Baulig <martin@gnome.org>
827 * debug.c (mono_debug_add_method): Include the `this' offset in
828 the `minfo->method_info.param_offsets' array.
830 2002-03-23 Martin Baulig <martin@gnome.org>
832 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
833 to do it before the X86_CMP.
834 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
835 (reg: CLT (lreg, lreg)): Likewise.

866 removed everything which is already in MonoDebugMethodInfo.
868 * debug.c (debug_generate_method_lines): Generate the MonoILOffsetInfo array.

907 * debug.c (mono_debug_get_type): Recursively call this for all function members
909 (mono_debug_add_method): Don't mangle function names, this must be done by the
910 debugger backend if the debugging format needs mangled names.
912 * debug-dwarf2.c: Improved support for classes, added member functions.
914 2002-03-16 Martin Baulig <martin@gnome.org>
916 * debug.c (mono_debug_get_type): Recursively call this for all members and
917 parent classes of a class type.
919 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
920 since GDB doesn't like Java very much.
922 2002-03-16 Martin Baulig <martin@gnome.org>
924 * debug-dwarf2.c: Added support for enums.
926 2002-03-15 Martin Baulig <martin@gnome.org>

947 * debug.c (MonoDebugFormat): New public enums specifying which debugging
949 (mono_debug_open_file): Added MonoDebugFormat argument.
950 (mono_debug_make_symbols): Don't take an argument to make it easier to call
951 this function from GDB. It's now safe to call this function multiple times;
952 it'll always write a complete debugging file.
954 * debug.c: Splitted this file into a general part which remains in this file
955 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
956 All public functions now call a corresponding format specific function.
958 * debug.c: The following changes are private to debug.c:
959 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
960 (record_line_number, debug_generate_method_lines): New private functions.
961 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
962 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
963 mono_debug_open_assembly_dwarf2).
964 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
965 now safe to call this function multiple times.
966 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
967 returns an unique index for this type. It's used to ensure that we only write
968 each class once to the debugging file.
969 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
970 data structure, but don't directly write to the debugging file. This is done
971 later from mono_debug_write_assembly().
973 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
974 debugging output. Call mono_debug_close() on cleanup if necessary.
976 2002-03-14 Martin Baulig <martin@gnome.org>
978 * debug-private.h: New private header file.
980 * debug-stabs.c: Added the stabs type generation stuff which was
981 previously in debug.c.
983 * debug-dwarf.c: Started to implement type support. We're currently
984 only writing this most basic types to the dwarf file, but this will
987 2002-03-13 Martin Baulig <martin@gnome.org>
989 * debug-stabs.c, debug-dwarf2.c: New files containing my new
990 debugging code. They're now in CVS, but not yet used anywhere.
992 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
994 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
995 macros, included new delegate code from Daniel Stodden.

1000 * jit.c: verify that corlib and runtime are in sync.
1002 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1004 * emit-x86.c, jit.c: use the debug-helpers facilities to
1005 describe and match a method when debugging.
1007 2002-03-10 Martin Baulig <martin@gnome.org>
1009 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1010 output, put a nop instruction at the start of all functions so that
1011 the adresses won't change when using --debug.
1013 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1014 the bytecode area, stabs needs a line number in the .il file. Use the
1015 new info->moffsets to get the line number.
1016 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1017 `moffsets' is an array of `total_lines' fields (total number of lines
1018 in the .il file); for each line in the .il field, this array contains
1019 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1020 of a method and 0 otherwise.
1021 (debug_load_method_lines): Read the whole .il file and initialize the
1022 info->moffsets field.
1024 2002-03-09 Martin Baulig <martin@gnome.org>
1026 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1027 the unnecessary CDQ instruction.
1029 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1031 * jit.c (mono_analyze_stack): only load addresses of value types
1032 on the runtime stack.
1034 2002-03-07 Duncan Mak <duncan@ximian.com>
1036 * Makefile.am: A small patch fixing errors in vpath-based builds
1037 (make clean failing to rerun monoburg due to BUILT_SOURCES usage),
1038 committed for Daniel Stodden <stodden@in.tum.de>.
1040 Thu Mar 7 17:22:52 CET 2002 Paolo Molaro <lupus@ximian.com>
