217 `int verbose' argument and made it public.

255 2002-05-21 Martin Baulig <martin@gnome.org>
257 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
258 file for all assemblies. Currently, the JIT doesn't put all methods
259 from a single assembly into a continuous region of memory. We were
260 previously creating valid DWARF 2 files for this, but unfortunately
261 GDB's symbol tables get messed up when it reads more than one such file.
263 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

575 * emit-x86.c, invoke.c: call profile callbacks if needed.
576 * jit.c, jit.h, mono.c: add --profile command line option.
578 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>

642 * jit.c (mono_jit_cleanup): added more statistics
644 * invoke.c (arch_create_native_wrapper): special case EndInvoke -
645 we need to pass the MonoMethod pointer as first argument.
647 * delegate.c (mono_async_invoke): notify all listeners, not only a
649 (arch_end_invoke): we now pass a MonoMethod as first parameter and
650 use arch_method_call_message_new() to access the stack.

717 (mono_debug_open_assembly): When using MONO_DEBUG_FORMAT_DWARF2_PLUS, fall back
718 to MONO_DEBUG_FORMAT_DWARF2 if the symbol file does not exist, but the IL file
720 (debug_generate_method_lines): Generate correct IL offsets.
722 2002-03-28 Martin Baulig <martin@gnome.org>

731 * debug.c (debug_generate_method_lines): Don't return if we don't have line
732 numbers, we still need to generate the IL offsets here. Emit line numbers
733 for `prologue_end_offset' (the first line of actual code) and
734 `epilogue_begin_offset' (the line of the method's closing brace).
735 Don't crash if cfg->bblocks [i].forest is NULL.
736 (mono_debug_add_method): Don't crash if we don't have line numbers.
737 Initialize the newly added fields.
739 * debug-stabs.c: Record first and last line, emit filename info at the
740 beginning of the stab file, gdb ignores the types otherwise.
742 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
743 emit line number info for the first and last line.
745 2002-03-28 Dietmar Maurer <dietmar@ximian.com>
747 * invoke.c (arch_create_delegate_trampoline): impl.
749 Thu Mar 28 11:58:53 CET 2002 Paolo Molaro <lupus@ximian.com>
751 * Makefile.am, mono.c, jit.h, jit.c: build the libmono library
752 with the jit runtime to easy embedding. main() is moved to mono.c, now.

754 * debug.h, debug.c: constify char* argument.
756 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

775 lines if we don't have line number information.
776 (write_method_dwarf2): Use `minfo->method_info.this_offset' instead
779 * debug-stabs.c (write_method_stabs): Don't generate method lines if
780 we don't have line number information. Use `minfo->method_info.this_offset'
781 instead of hardcoding 8.
783 * debug.c (debug_generate_method_lines): Don't crash if we don't have
784 line number information.
785 (mono_debug_open_assembly): Don't generate line numbers for
786 MONO_DEBUG_FORMAT_DWARF2_PLUS.
787 (mono_debug_add_method): Don't store the 'this' offset in `param_offsets',
788 but it in the new `this_offset' field.
790 Mon Mar 25 13:03:35 CET 2002 Paolo Molaro <lupus@ximian.com>
792 * debug.c (debug_generate_method_lines): Use correct addresses for

804 2002-03-24 Martin Baulig <martin@gnome.org>
806 * debug.c (mono_debug_add_method): Include the `this' offset in
807 the `minfo->method_info.param_offsets' array.
809 2002-03-23 Martin Baulig <martin@gnome.org>
811 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
812 to do it before the X86_CMP.
813 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
814 (reg: CLT (lreg, lreg)): Likewise.

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

886 * debug.c (mono_debug_get_type): Recursively call this for all function members
888 (mono_debug_add_method): Don't mangle function names, this must be done by the
889 debugger backend if the debugging format needs mangled names.
891 * debug-dwarf2.c: Improved support for classes, added member functions.
893 2002-03-16 Martin Baulig <martin@gnome.org>
895 * debug.c (mono_debug_get_type): Recursively call this for all members and
896 parent classes of a class type.
898 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
899 since GDB doesn't like Java very much.
901 2002-03-16 Martin Baulig <martin@gnome.org>
903 * debug-dwarf2.c: Added support for enums.
905 2002-03-15 Martin Baulig <martin@gnome.org>

926 * debug.c (MonoDebugFormat): New public enums specifying which debugging
928 (mono_debug_open_file): Added MonoDebugFormat argument.
929 (mono_debug_make_symbols): Don't take an argument to make it easier to call
930 this function from GDB. It's now safe to call this function multiple times;
931 it'll always write a complete debugging file.
933 * debug.c: Splitted this file into a general part which remains in this file
934 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
935 All public functions now call a corresponding format specific function.
937 * debug.c: The following changes are private to debug.c:
938 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
939 (record_line_number, debug_generate_method_lines): New private functions.
940 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
941 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
942 mono_debug_open_assembly_dwarf2).
943 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
944 now safe to call this function multiple times.
945 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
946 returns an unique index for this type. It's used to ensure that we only write
947 each class once to the debugging file.
948 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
949 data structure, but don't directly write to the debugging file. This is done
950 later from mono_debug_write_assembly().
952 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
953 debugging output. Call mono_debug_close() on cleanup if necessary.
955 2002-03-14 Martin Baulig <martin@gnome.org>
957 * debug-private.h: New private header file.
959 * debug-stabs.c: Added the stabs type generation stuff which was
960 previously in debug.c.

963 only writing this most basic types to the dwarf file, but this will
966 2002-03-13 Martin Baulig <martin@gnome.org>
968 * debug-stabs.c, debug-dwarf2.c: New files containing my new
969 debugging code. They're now in CVS, but not yet used anywhere.
971 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
973 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
974 macros, included new delegate code from Daniel Stodden.

979 * jit.c: verify that corlib and runtime are in sync.
981 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
983 * emit-x86.c, jit.c: use the debug-helpers facilities to
984 describe and match a method when debugging.
986 2002-03-10 Martin Baulig <martin@gnome.org>
988 * emit-x86.c (arch_compile_method): When emitting stabs debugging
989 output, put a nop instruction at the start of all functions so that
990 the adresses won't change when using --debug.
992 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
993 the bytecode area, stabs needs a line number in the .il file. Use the
994 new info->moffsets to get the line number.
995 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
996 `moffsets' is an array of `total_lines' fields (total number of lines
997 in the .il file); for each line in the .il field, this array contains
998 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
999 of a method and 0 otherwise.
1000 (debug_load_method_lines): Read the whole .il file and initialize the
1001 info->moffsets field.
1003 2002-03-09 Martin Baulig <martin@gnome.org>
1005 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1006 the unnecessary CDQ instruction.
1008 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1010 * jit.c (mono_analyze_stack): only load addresses of value types
1011 on the runtime stack.
1013 2002-03-07 Duncan Mak <duncan@ximian.com>
1015 * Makefile.am: A small patch fixing errors in vpath-based builds
1016 (make clean failing to rerun monoburg due to BUILT_SOURCES usage),
1017 committed for Daniel Stodden <stodden@in.tum.de>.
1019 Thu Mar 7 17:22:52 CET 2002 Paolo Molaro <lupus@ximian.com>

1084 Sun Feb 24 13:58:34 CET 2002 Paolo Molaro <lupus@ximian.com>
1086 * jit.h, jit.c, emit-x86.c: Added a few statistics counters
1087 and the --stats command line option to print them.
