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

817 * debug.c (debug_generate_method_lines): Don't return if we don't have line
818 numbers, we still need to generate the IL offsets here. Emit line numbers
819 for `prologue_end_offset' (the first line of actual code) and
820 `epilogue_begin_offset' (the line of the method's closing brace).
821 Don't crash if cfg->bblocks [i].forest is NULL.
822 (mono_debug_add_method): Don't crash if we don't have line numbers.
823 Initialize the newly added fields.
825 * debug-stabs.c: Record first and last line, emit filename info at the
826 beginning of the stab file, gdb ignores the types otherwise.
828 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
829 emit line number info for the first and last line.
831 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

895 2002-03-23 Martin Baulig <martin@gnome.org>
897 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
898 to do it before the X86_CMP.
899 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
900 (reg: CLT (lreg, lreg)): Likewise.

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

1014 (mono_debug_open_file): Added MonoDebugFormat argument.
1015 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1016 this function from GDB. It's now safe to call this function multiple times;
1017 it'll always write a complete debugging file.
1019 * debug.c: Splitted this file into a general part which remains in this file
1020 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1021 All public functions now call a corresponding format specific function.
1023 * debug.c: The following changes are private to debug.c:
1024 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1025 (record_line_number, debug_generate_method_lines): New private functions.
1026 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1027 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1028 mono_debug_open_assembly_dwarf2).
1029 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1030 now safe to call this function multiple times.
1031 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1032 returns an unique index for this type. It's used to ensure that we only write
1033 each class once to the debugging file.
1034 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1035 data structure, but don't directly write to the debugging file. This is done
1036 later from mono_debug_write_assembly().
1038 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1039 debugging output. Call mono_debug_close() on cleanup if necessary.

1043 * debug-private.h: New private header file.
1045 * debug-stabs.c: Added the stabs type generation stuff which was
1046 previously in debug.c.
1048 * debug-dwarf.c: Started to implement type support. We're currently
1049 only writing this most basic types to the dwarf file, but this will
1052 2002-03-13 Martin Baulig <martin@gnome.org>
1054 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1055 debugging code. They're now in CVS, but not yet used anywhere.
1057 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1059 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*

1065 * jit.c: verify that corlib and runtime are in sync.
1067 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1069 * emit-x86.c, jit.c: use the debug-helpers facilities to
1070 describe and match a method when debugging.
1072 2002-03-10 Martin Baulig <martin@gnome.org>
1074 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1075 output, put a nop instruction at the start of all functions so that
1076 the adresses won't change when using --debug.
1078 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1079 the bytecode area, stabs needs a line number in the .il file. Use the
1080 new info->moffsets to get the line number.
1081 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1082 `moffsets' is an array of `total_lines' fields (total number of lines
1083 in the .il file); for each line in the .il field, this array contains
1084 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1085 of a method and 0 otherwise.
1086 (debug_load_method_lines): Read the whole .il file and initialize the
1087 info->moffsets field.
1089 2002-03-09 Martin Baulig <martin@gnome.org>
1091 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1092 the unnecessary CDQ instruction.
1094 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1096 * jit.c (mono_analyze_stack): only load addresses of value types
1097 on the runtime stack.
1099 2002-03-07 Duncan Mak <duncan@ximian.com>
1101 * Makefile.am: A small patch fixing errors in vpath-based builds
1102 (make clean failing to rerun monoburg due to BUILT_SOURCES usage),
1103 committed for Daniel Stodden <stodden@in.tum.de>.

1742 * testjit.c (tree_get_address): impl. to fix address bug
1743 (tree_get_address): make sure that we can only jump to the first
1744 instruction of a tree.
1746 * x86.brg: emit real code for calls
1748 * testjit.c (create_jit_trampoline): creates a function to trigger jit
1750 (mono_compile_method): reversed argument order
1752 2001-09-15 Dietmar Maurer <dietmar@ximian.com>
1754 * x86.brg (stmt): don't emit unnecessary register moves
1756 * testjit.c (tree_allocate_regs): free registers earlier
1758 2001-09-14 Dietmar Maurer <dietmar@ximian.com>
1760 * x86.brg: branch addresses are now resolved
1762 * testjit.c (compute_branches): compute address of branches
1764 * x86.brg: emit real x86 instructions
1766 * testjit.c: call objdump to disassemble the output
1768 2001-09-13 Dietmar Maurer <dietmar@ximian.com>
1770 * x86.brg: use the right offsets to access local variables
1773 * emit-x86.c: only save/restore callee saved registers if they are
1776 * testjit.c (tree_allocate_regs): use the new MonoRegSet to
1778 (mono_compile_method): changed the tree for mothod calls
1785 2001-09-10 Miguel de Icaza <miguel@ximian.com>
1787 * x86.brg: Use Unix assembly syntax.
1789 * emit-x86.c: support code, should be moved
1791 * testjit.c: Use GPtrArrays instead of GLists, as those are very
1792 inefficient at appends.
1794 * Renamed `create_new_leave' to `create_new_leaf'
