338 2002-05-21 Martin Baulig <martin@gnome.org>
340 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
341 file for all assemblies. Currently, the JIT doesn't put all methods
342 from a single assembly into a continuous region of memory. We were
343 previously creating valid DWARF 2 files for this, but unfortunately
344 GDB's symbol tables get messed up when it reads more than one such file.
346 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

728 we need to pass the MonoMethod pointer as first argument.

814 * debug.c (debug_generate_method_lines): Don't return if we don't have line
815 numbers, we still need to generate the IL offsets here. Emit line numbers
816 for `prologue_end_offset' (the first line of actual code) and
817 `epilogue_begin_offset' (the line of the method's closing brace).
818 Don't crash if cfg->bblocks [i].forest is NULL.
819 (mono_debug_add_method): Don't crash if we don't have line numbers.
820 Initialize the newly added fields.
822 * debug-stabs.c: Record first and last line, emit filename info at the
823 beginning of the stab file, gdb ignores the types otherwise.
825 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
826 emit line number info for the first and last line.
828 2002-03-28 Dietmar Maurer <dietmar@ximian.com>
830 * invoke.c (arch_create_delegate_trampoline): impl.
832 Thu Mar 28 11:58:53 CET 2002 Paolo Molaro <lupus@ximian.com>
834 * Makefile.am, mono.c, jit.h, jit.c: build the libmono library
835 with the jit runtime to easy embedding. main() is moved to mono.c, now.

839 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

863 we don't have line number information. Use `minfo->method_info.this_offset'
864 instead of hardcoding 8.
866 * debug.c (debug_generate_method_lines): Don't crash if we don't have
867 line number information.

881 * Makefile.am: link to libmonoutils.
883 2002-03-25 Martin Baulig <martin@gnome.org>
885 * debug.h (mono_debug_make_symbols): Documented this function.

889 * debug.c (mono_debug_add_method): Include the `this' offset in
890 the `minfo->method_info.param_offsets' array.
892 2002-03-23 Martin Baulig <martin@gnome.org>
894 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
895 to do it before the X86_CMP.
896 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
897 (reg: CLT (lreg, lreg)): Likewise.

922 * debug.h (MonoDebugFormat): Added MONO_DEBUG_FORMAT_DWARF2_PLUS.
924 * debug-dwarf2-plus.c: This debugging format reads a symbol file which has

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

969 * debug.c (mono_debug_get_type): Recursively call this for all function members
971 (mono_debug_add_method): Don't mangle function names, this must be done by the
972 debugger backend if the debugging format needs mangled names.
974 * debug-dwarf2.c: Improved support for classes, added member functions.
976 2002-03-16 Martin Baulig <martin@gnome.org>
978 * debug.c (mono_debug_get_type): Recursively call this for all members and
979 parent classes of a class type.

984 2002-03-16 Martin Baulig <martin@gnome.org>
986 * debug-dwarf2.c: Added support for enums.
988 2002-03-15 Martin Baulig <martin@gnome.org>

1009 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1011 (mono_debug_open_file): Added MonoDebugFormat argument.
1012 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1013 this function from GDB. It's now safe to call this function multiple times;
1014 it'll always write a complete debugging file.
1016 * debug.c: Splitted this file into a general part which remains in this file
1017 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1018 All public functions now call a corresponding format specific function.
1020 * debug.c: The following changes are private to debug.c:
1021 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1022 (record_line_number, debug_generate_method_lines): New private functions.
1023 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1024 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1025 mono_debug_open_assembly_dwarf2).
1026 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1027 now safe to call this function multiple times.
1028 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1029 returns an unique index for this type. It's used to ensure that we only write
1030 each class once to the debugging file.
1031 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1032 data structure, but don't directly write to the debugging file. This is done
1033 later from mono_debug_write_assembly().
1035 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1036 debugging output. Call mono_debug_close() on cleanup if necessary.
1038 2002-03-14 Martin Baulig <martin@gnome.org>
1040 * debug-private.h: New private header file.
1042 * debug-stabs.c: Added the stabs type generation stuff which was
1043 previously in debug.c.
1045 * debug-dwarf.c: Started to implement type support. We're currently
1046 only writing this most basic types to the dwarf file, but this will
1049 2002-03-13 Martin Baulig <martin@gnome.org>
1051 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1052 debugging code. They're now in CVS, but not yet used anywhere.
1054 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1056 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1057 macros, included new delegate code from Daniel Stodden.
1060 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1062 * jit.c: verify that corlib and runtime are in sync.
1064 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1066 * emit-x86.c, jit.c: use the debug-helpers facilities to
1067 describe and match a method when debugging.
1069 2002-03-10 Martin Baulig <martin@gnome.org>
1071 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1072 output, put a nop instruction at the start of all functions so that
1073 the adresses won't change when using --debug.
1075 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1076 the bytecode area, stabs needs a line number in the .il file. Use the
1077 new info->moffsets to get the line number.
1078 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1079 `moffsets' is an array of `total_lines' fields (total number of lines
1080 in the .il file); for each line in the .il field, this array contains
1081 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1082 of a method and 0 otherwise.
1083 (debug_load_method_lines): Read the whole .il file and initialize the
1084 info->moffsets field.
1086 2002-03-09 Martin Baulig <martin@gnome.org>
1088 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1089 the unnecessary CDQ instruction.
1091 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1093 * jit.c (mono_analyze_stack): only load addresses of value types
1094 on the runtime stack.
1096 2002-03-07 Duncan Mak <duncan@ximian.com>
1098 * Makefile.am: A small patch fixing errors in vpath-based builds
1099 (make clean failing to rerun monoburg due to BUILT_SOURCES usage),
1100 committed for Daniel Stodden <stodden@in.tum.de>.
1102 Thu Mar 7 17:22:52 CET 2002 Paolo Molaro <lupus@ximian.com>

1739 * testjit.c (tree_get_address): impl. to fix address bug
1740 (tree_get_address): make sure that we can only jump to the first
1741 instruction of a tree.
1743 * x86.brg: emit real code for calls
1745 * testjit.c (create_jit_trampoline): creates a function to trigger jit
1747 (mono_compile_method): reversed argument order
1749 2001-09-15 Dietmar Maurer <dietmar@ximian.com>
1751 * x86.brg (stmt): don't emit unnecessary register moves
1753 * testjit.c (tree_allocate_regs): free registers earlier
1755 2001-09-14 Dietmar Maurer <dietmar@ximian.com>
1757 * x86.brg: branch addresses are now resolved
1759 * testjit.c (compute_branches): compute address of branches
1761 * x86.brg: emit real x86 instructions
1763 * testjit.c: call objdump to disassemble the output
1765 2001-09-13 Dietmar Maurer <dietmar@ximian.com>
1767 * x86.brg: use the right offsets to access local variables
1770 * emit-x86.c: only save/restore callee saved registers if they are
1773 * testjit.c (tree_allocate_regs): use the new MonoRegSet to
1775 (mono_compile_method): changed the tree for mothod calls
1782 2001-09-10 Miguel de Icaza <miguel@ximian.com>
1784 * x86.brg: Use Unix assembly syntax.
1786 * emit-x86.c: support code, should be moved
1788 * testjit.c: Use GPtrArrays instead of GLists, as those are very
1789 inefficient at appends.
1791 * Renamed `create_new_leave' to `create_new_leaf'
