344 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
345 file for all assemblies. Currently, the JIT doesn't put all methods
346 from a single assembly into a continuous region of memory. We were

818 * debug.c (debug_generate_method_lines): Don't return if we don't have line
819 numbers, we still need to generate the IL offsets here. Emit line numbers
820 for `prologue_end_offset' (the first line of actual code) and
821 `epilogue_begin_offset' (the line of the method's closing brace).
822 Don't crash if cfg->bblocks [i].forest is NULL.
823 (mono_debug_add_method): Don't crash if we don't have line numbers.
824 Initialize the newly added fields.
826 * debug-stabs.c: Record first and last line, emit filename info at the
827 beginning of the stab file, gdb ignores the types otherwise.
829 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
830 emit line number info for the first and last line.
832 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

896 2002-03-23 Martin Baulig <martin@gnome.org>
898 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
899 to do it before the X86_CMP.
900 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
901 (reg: CLT (lreg, lreg)): Likewise.

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

1013 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1015 (mono_debug_open_file): Added MonoDebugFormat argument.
1016 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1017 this function from GDB. It's now safe to call this function multiple times;
1018 it'll always write a complete debugging file.
1020 * debug.c: Splitted this file into a general part which remains in this file
1021 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1022 All public functions now call a corresponding format specific function.
1024 * debug.c: The following changes are private to debug.c:
1025 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1026 (record_line_number, debug_generate_method_lines): New private functions.
1027 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1028 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1029 mono_debug_open_assembly_dwarf2).
1030 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1031 now safe to call this function multiple times.
1032 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1033 returns an unique index for this type. It's used to ensure that we only write
1034 each class once to the debugging file.
1035 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1036 data structure, but don't directly write to the debugging file. This is done
1037 later from mono_debug_write_assembly().
1039 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1040 debugging output. Call mono_debug_close() on cleanup if necessary.

1044 * debug-private.h: New private header file.
1046 * debug-stabs.c: Added the stabs type generation stuff which was
1047 previously in debug.c.

1050 only writing this most basic types to the dwarf file, but this will
1053 2002-03-13 Martin Baulig <martin@gnome.org>
1055 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1056 debugging code. They're now in CVS, but not yet used anywhere.
1058 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1060 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*

1066 * jit.c: verify that corlib and runtime are in sync.
1068 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1070 * emit-x86.c, jit.c: use the debug-helpers facilities to
1071 describe and match a method when debugging.
1073 2002-03-10 Martin Baulig <martin@gnome.org>
1075 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1076 output, put a nop instruction at the start of all functions so that
1077 the adresses won't change when using --debug.
1079 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1080 the bytecode area, stabs needs a line number in the .il file. Use the
1081 new info->moffsets to get the line number.
1082 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1083 `moffsets' is an array of `total_lines' fields (total number of lines
1084 in the .il file); for each line in the .il field, this array contains
1085 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1086 of a method and 0 otherwise.
1087 (debug_load_method_lines): Read the whole .il file and initialize the
1088 info->moffsets field.
1090 2002-03-09 Martin Baulig <martin@gnome.org>
1092 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1093 the unnecessary CDQ instruction.
1095 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1097 * jit.c (mono_analyze_stack): only load addresses of value types
1098 on the runtime stack.
1100 2002-03-07 Duncan Mak <duncan@ximian.com>
1102 * Makefile.am: A small patch fixing errors in vpath-based builds
1103 (make clean failing to rerun monoburg due to BUILT_SOURCES usage),
1104 committed for Daniel Stodden <stodden@in.tum.de>.

1741 2001-09-17 Dietmar Maurer <dietmar@ximian.com>
1743 * testjit.c (tree_get_address): impl. to fix address bug
1744 (tree_get_address): make sure that we can only jump to the first
1745 instruction of a tree.
1747 * x86.brg: emit real code for calls
1749 * testjit.c (create_jit_trampoline): creates a function to trigger jit
1751 (mono_compile_method): reversed argument order
1753 2001-09-15 Dietmar Maurer <dietmar@ximian.com>
1755 * x86.brg (stmt): don't emit unnecessary register moves
1757 * testjit.c (tree_allocate_regs): free registers earlier
1759 2001-09-14 Dietmar Maurer <dietmar@ximian.com>
1761 * x86.brg: branch addresses are now resolved
1763 * testjit.c (compute_branches): compute address of branches
1765 * x86.brg: emit real x86 instructions
1767 * testjit.c: call objdump to disassemble the output
1769 2001-09-13 Dietmar Maurer <dietmar@ximian.com>
1771 * x86.brg: use the right offsets to access local variables
1774 * emit-x86.c: only save/restore callee saved registers if they are
1777 * testjit.c (tree_allocate_regs): use the new MonoRegSet to
1779 (mono_compile_method): changed the tree for mothod calls
1786 2001-09-10 Miguel de Icaza <miguel@ximian.com>
1788 * x86.brg: Use Unix assembly syntax.
1790 * emit-x86.c: support code, should be moved
1792 * testjit.c: Use GPtrArrays instead of GLists, as those are very
1793 inefficient at appends.
1795 * Renamed `create_new_leave' to `create_new_leaf'
