225 `const char **args' argument.
227 * mono.c (mono_jit_assembly): Renamed to mono_jit_compile_image(), added
228 `int verbose' argument and made it public.

266 2002-05-21 Martin Baulig <martin@gnome.org>
268 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
269 file for all assemblies. Currently, the JIT doesn't put all methods
270 from a single assembly into a continuous region of memory. We were
271 previously creating valid DWARF 2 files for this, but unfortunately
272 GDB's symbol tables get messed up when it reads more than one such file.
274 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

586 * emit-x86.c, invoke.c: call profile callbacks if needed.
587 * jit.c, jit.h, mono.c: add --profile command line option.
589 2002-04-16 Gonzalo Paniagua Javier <gonzalo@ximian.com>

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

728 (mono_debug_open_assembly): When using MONO_DEBUG_FORMAT_DWARF2_PLUS, fall back
729 to MONO_DEBUG_FORMAT_DWARF2 if the symbol file does not exist, but the IL file
731 (debug_generate_method_lines): Generate correct IL offsets.
733 2002-03-28 Martin Baulig <martin@gnome.org>

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

765 * debug.h, debug.c: constify char* argument.
767 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

790 * debug-stabs.c (write_method_stabs): Don't generate method lines if
791 we don't have line number information. Use `minfo->method_info.this_offset'
792 instead of hardcoding 8.
794 * debug.c (debug_generate_method_lines): Don't crash if we don't have
795 line number information.

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

820 2002-03-23 Martin Baulig <martin@gnome.org>
822 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
823 to do it before the X86_CMP.
824 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
825 (reg: CLT (lreg, lreg)): Likewise.

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

897 * debug.c (mono_debug_get_type): Recursively call this for all function members
899 (mono_debug_add_method): Don't mangle function names, this must be done by the
900 debugger backend if the debugging format needs mangled names.
902 * debug-dwarf2.c: Improved support for classes, added member functions.
904 2002-03-16 Martin Baulig <martin@gnome.org>
906 * debug.c (mono_debug_get_type): Recursively call this for all members and
907 parent classes of a class type.
909 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
910 since GDB doesn't like Java very much.
912 2002-03-16 Martin Baulig <martin@gnome.org>
914 * debug-dwarf2.c: Added support for enums.
916 2002-03-15 Martin Baulig <martin@gnome.org>

937 * debug.c (MonoDebugFormat): New public enums specifying which debugging
939 (mono_debug_open_file): Added MonoDebugFormat argument.
940 (mono_debug_make_symbols): Don't take an argument to make it easier to call
941 this function from GDB. It's now safe to call this function multiple times;
942 it'll always write a complete debugging file.
944 * debug.c: Splitted this file into a general part which remains in this file
945 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
946 All public functions now call a corresponding format specific function.
948 * debug.c: The following changes are private to debug.c:
949 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
950 (record_line_number, debug_generate_method_lines): New private functions.
951 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
952 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
953 mono_debug_open_assembly_dwarf2).
954 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
955 now safe to call this function multiple times.
956 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
957 returns an unique index for this type. It's used to ensure that we only write
958 each class once to the debugging file.
959 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
960 data structure, but don't directly write to the debugging file. This is done
961 later from mono_debug_write_assembly().
963 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
964 debugging output. Call mono_debug_close() on cleanup if necessary.
966 2002-03-14 Martin Baulig <martin@gnome.org>
968 * debug-private.h: New private header file.
970 * debug-stabs.c: Added the stabs type generation stuff which was
971 previously in debug.c.

974 only writing this most basic types to the dwarf file, but this will
977 2002-03-13 Martin Baulig <martin@gnome.org>
979 * debug-stabs.c, debug-dwarf2.c: New files containing my new
980 debugging code. They're now in CVS, but not yet used anywhere.
982 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
984 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
985 macros, included new delegate code from Daniel Stodden.

990 * jit.c: verify that corlib and runtime are in sync.
992 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
994 * emit-x86.c, jit.c: use the debug-helpers facilities to
995 describe and match a method when debugging.
997 2002-03-10 Martin Baulig <martin@gnome.org>
999 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1000 output, put a nop instruction at the start of all functions so that
1001 the adresses won't change when using --debug.
1003 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1004 the bytecode area, stabs needs a line number in the .il file. Use the
1005 new info->moffsets to get the line number.
1006 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1007 `moffsets' is an array of `total_lines' fields (total number of lines
1008 in the .il file); for each line in the .il field, this array contains
1009 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1010 of a method and 0 otherwise.
1011 (debug_load_method_lines): Read the whole .il file and initialize the
1012 info->moffsets field.
1014 2002-03-09 Martin Baulig <martin@gnome.org>
1016 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1017 the unnecessary CDQ instruction.
1019 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1021 * jit.c (mono_analyze_stack): only load addresses of value types
1022 on the runtime stack.
1024 2002-03-07 Duncan Mak <duncan@ximian.com>
1026 * Makefile.am: A small patch fixing errors in vpath-based builds
1027 (make clean failing to rerun monoburg due to BUILT_SOURCES usage),
