327 2002-05-21 Martin Baulig <martin@gnome.org>
329 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
330 file for all assemblies. Currently, the JIT doesn't put all methods
331 from a single assembly into a continuous region of memory. We were
332 previously creating valid DWARF 2 files for this, but unfortunately
333 GDB's symbol tables get messed up when it reads more than one such file.
335 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

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

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

803 * debug.c (debug_generate_method_lines): Don't return if we don't have line
804 numbers, we still need to generate the IL offsets here. Emit line numbers
805 for `prologue_end_offset' (the first line of actual code) and
806 `epilogue_begin_offset' (the line of the method's closing brace).
807 Don't crash if cfg->bblocks [i].forest is NULL.
808 (mono_debug_add_method): Don't crash if we don't have line numbers.
809 Initialize the newly added fields.
811 * debug-stabs.c: Record first and last line, emit filename info at the
812 beginning of the stab file, gdb ignores the types otherwise.
814 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
815 emit line number info for the first and last line.
817 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

828 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

879 the `minfo->method_info.param_offsets' array.
881 2002-03-23 Martin Baulig <martin@gnome.org>
883 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
884 to do it before the X86_CMP.
885 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
886 (reg: CLT (lreg, lreg)): Likewise.

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

958 * debug.c (mono_debug_get_type): Recursively call this for all function members
960 (mono_debug_add_method): Don't mangle function names, this must be done by the
961 debugger backend if the debugging format needs mangled names.
963 * debug-dwarf2.c: Improved support for classes, added member functions.
965 2002-03-16 Martin Baulig <martin@gnome.org>

973 2002-03-16 Martin Baulig <martin@gnome.org>
975 * debug-dwarf2.c: Added support for enums.
977 2002-03-15 Martin Baulig <martin@gnome.org>

998 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1000 (mono_debug_open_file): Added MonoDebugFormat argument.
1001 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1002 this function from GDB. It's now safe to call this function multiple times;
1003 it'll always write a complete debugging file.
1005 * debug.c: Splitted this file into a general part which remains in this file
1006 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1007 All public functions now call a corresponding format specific function.
1009 * debug.c: The following changes are private to debug.c:
1010 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1011 (record_line_number, debug_generate_method_lines): New private functions.
1012 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1013 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1014 mono_debug_open_assembly_dwarf2).
1015 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1016 now safe to call this function multiple times.
1017 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1018 returns an unique index for this type. It's used to ensure that we only write
1019 each class once to the debugging file.
1020 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1021 data structure, but don't directly write to the debugging file. This is done
1022 later from mono_debug_write_assembly().
1024 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1025 debugging output. Call mono_debug_close() on cleanup if necessary.
1027 2002-03-14 Martin Baulig <martin@gnome.org>
1029 * debug-private.h: New private header file.
1031 * debug-stabs.c: Added the stabs type generation stuff which was
1032 previously in debug.c.
1034 * debug-dwarf.c: Started to implement type support. We're currently
1035 only writing this most basic types to the dwarf file, but this will
1038 2002-03-13 Martin Baulig <martin@gnome.org>
1040 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1041 debugging code. They're now in CVS, but not yet used anywhere.
1043 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1045 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1046 macros, included new delegate code from Daniel Stodden.

1051 * jit.c: verify that corlib and runtime are in sync.
1053 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1055 * emit-x86.c, jit.c: use the debug-helpers facilities to
1056 describe and match a method when debugging.
1058 2002-03-10 Martin Baulig <martin@gnome.org>
1060 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1061 output, put a nop instruction at the start of all functions so that
1062 the adresses won't change when using --debug.
1064 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1065 the bytecode area, stabs needs a line number in the .il file. Use the
1066 new info->moffsets to get the line number.
1067 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1068 `moffsets' is an array of `total_lines' fields (total number of lines
1069 in the .il file); for each line in the .il field, this array contains
1070 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1071 of a method and 0 otherwise.
1072 (debug_load_method_lines): Read the whole .il file and initialize the
1073 info->moffsets field.
1075 2002-03-09 Martin Baulig <martin@gnome.org>
1077 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1078 the unnecessary CDQ instruction.
1080 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1082 * jit.c (mono_analyze_stack): only load addresses of value types
1083 on the runtime stack.
1085 2002-03-07 Duncan Mak <duncan@ximian.com>
1087 * Makefile.am: A small patch fixing errors in vpath-based builds
1088 (make clean failing to rerun monoburg due to BUILT_SOURCES usage),
1089 committed for Daniel Stodden <stodden@in.tum.de>.

1149 (mono_compute_branches): patch real jump address (instead of
1150 emitting code twice)
1152 Tue Feb 26 11:56:03 CET 2002 Paolo Molaro <lupus@ximian.com>

1736 (mono_compile_method): reversed argument order
1738 2001-09-15 Dietmar Maurer <dietmar@ximian.com>
1740 * x86.brg (stmt): don't emit unnecessary register moves
1742 * testjit.c (tree_allocate_regs): free registers earlier
1744 2001-09-14 Dietmar Maurer <dietmar@ximian.com>
1746 * x86.brg: branch addresses are now resolved
1748 * testjit.c (compute_branches): compute address of branches
1750 * x86.brg: emit real x86 instructions
1752 * testjit.c: call objdump to disassemble the output
1754 2001-09-13 Dietmar Maurer <dietmar@ximian.com>
1756 * x86.brg: use the right offsets to access local variables
1759 * emit-x86.c: only save/restore callee saved registers if they are
1762 * testjit.c (tree_allocate_regs): use the new MonoRegSet to
1764 (mono_compile_method): changed the tree for mothod calls
1771 2001-09-10 Miguel de Icaza <miguel@ximian.com>
1773 * x86.brg: Use Unix assembly syntax.
1775 * emit-x86.c: support code, should be moved
1777 * testjit.c: Use GPtrArrays instead of GLists, as those are very
1778 inefficient at appends.
1780 * Renamed `create_new_leave' to `create_new_leaf'
