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

827 * debug.c (debug_generate_method_lines): Don't return if we don't have line
828 numbers, we still need to generate the IL offsets here. Emit line numbers
829 for `prologue_end_offset' (the first line of actual code) and
830 `epilogue_begin_offset' (the line of the method's closing brace).
831 Don't crash if cfg->bblocks [i].forest is NULL.
832 (mono_debug_add_method): Don't crash if we don't have line numbers.
833 Initialize the newly added fields.
835 * debug-stabs.c: Record first and last line, emit filename info at the
836 beginning of the stab file, gdb ignores the types otherwise.
838 * debug-dwarf2.c: Use the new prologue_end_offset instead of guessing it;
839 emit line number info for the first and last line.
841 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

905 2002-03-23 Martin Baulig <martin@gnome.org>
907 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
908 to do it before the X86_CMP.
909 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
910 (reg: CLT (lreg, lreg)): Likewise.

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

1022 * debug.c (MonoDebugFormat): New public enums specifying which debugging
1024 (mono_debug_open_file): Added MonoDebugFormat argument.
1025 (mono_debug_make_symbols): Don't take an argument to make it easier to call
1026 this function from GDB. It's now safe to call this function multiple times;
1027 it'll always write a complete debugging file.
1029 * debug.c: Splitted this file into a general part which remains in this file
1030 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
1031 All public functions now call a corresponding format specific function.
1033 * debug.c: The following changes are private to debug.c:
1034 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1035 (record_line_number, debug_generate_method_lines): New private functions.
1036 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1037 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1038 mono_debug_open_assembly_dwarf2).
1039 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1040 now safe to call this function multiple times.
1041 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1042 returns an unique index for this type. It's used to ensure that we only write
1043 each class once to the debugging file.
1044 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1045 data structure, but don't directly write to the debugging file. This is done
1046 later from mono_debug_write_assembly().
1048 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1049 debugging output. Call mono_debug_close() on cleanup if necessary.

1053 * debug-private.h: New private header file.
1055 * debug-stabs.c: Added the stabs type generation stuff which was
1056 previously in debug.c.
1058 * debug-dwarf.c: Started to implement type support. We're currently
1059 only writing this most basic types to the dwarf file, but this will
1062 2002-03-13 Martin Baulig <martin@gnome.org>
1064 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1065 debugging code. They're now in CVS, but not yet used anywhere.
1067 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1069 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1070 macros, included new delegate code from Daniel Stodden.
1073 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1075 * jit.c: verify that corlib and runtime are in sync.
1077 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1079 * emit-x86.c, jit.c: use the debug-helpers facilities to
1080 describe and match a method when debugging.
1082 2002-03-10 Martin Baulig <martin@gnome.org>
1084 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1085 output, put a nop instruction at the start of all functions so that
1086 the adresses won't change when using --debug.
1088 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1089 the bytecode area, stabs needs a line number in the .il file. Use the
1090 new info->moffsets to get the line number.
1091 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1092 `moffsets' is an array of `total_lines' fields (total number of lines
1093 in the .il file); for each line in the .il field, this array contains
1094 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1095 of a method and 0 otherwise.
1096 (debug_load_method_lines): Read the whole .il file and initialize the
1097 info->moffsets field.
1099 2002-03-09 Martin Baulig <martin@gnome.org>
1101 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1102 the unnecessary CDQ instruction.
1104 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1106 * jit.c (mono_analyze_stack): only load addresses of value types
1107 on the runtime stack.
1109 2002-03-07 Duncan Mak <duncan@ximian.com>
1111 * Makefile.am: A small patch fixing errors in vpath-based builds
1112 (make clean failing to rerun monoburg due to BUILT_SOURCES usage),
1113 committed for Daniel Stodden <stodden@in.tum.de>.
1115 Thu Mar 7 17:22:52 CET 2002 Paolo Molaro <lupus@ximian.com>

1152 2002-02-28 Dietmar Maurer <dietmar@ximian.com>
1154 * emit-x86.c (arch_create_jit_trampoline): save/restore LMF before
1155 calling into unmanaged code (arch_compile_method).

1742 Tue Sep 18 13:19:16 CEST 2001 Paolo Molaro <lupus@ximian.com>
1744 * testjit.c: better/faster align code. Handle ldloc.s and stloc.s.
1746 2001-09-17 Miguel de Icaza <miguel@ximian.com>
1748 * testjit.c (mono_compile_method): Provide better error reporting.
1750 2001-09-17 Dietmar Maurer <dietmar@ximian.com>
1752 * testjit.c (tree_get_address): impl. to fix address bug
1753 (tree_get_address): make sure that we can only jump to the first
1754 instruction of a tree.
1756 * x86.brg: emit real code for calls
1758 * testjit.c (create_jit_trampoline): creates a function to trigger jit
1760 (mono_compile_method): reversed argument order
1762 2001-09-15 Dietmar Maurer <dietmar@ximian.com>
1764 * x86.brg (stmt): don't emit unnecessary register moves
1766 * testjit.c (tree_allocate_regs): free registers earlier
1768 2001-09-14 Dietmar Maurer <dietmar@ximian.com>
1770 * x86.brg: branch addresses are now resolved
1772 * testjit.c (compute_branches): compute address of branches
1774 * x86.brg: emit real x86 instructions
1776 * testjit.c: call objdump to disassemble the output
1778 2001-09-13 Dietmar Maurer <dietmar@ximian.com>
1780 * x86.brg: use the right offsets to access local variables
1783 * emit-x86.c: only save/restore callee saved registers if they are
1786 * testjit.c (tree_allocate_regs): use the new MonoRegSet to
1788 (mono_compile_method): changed the tree for mothod calls
1795 2001-09-10 Miguel de Icaza <miguel@ximian.com>
1797 * x86.brg: Use Unix assembly syntax.
1799 * emit-x86.c: support code, should be moved
1801 * testjit.c: Use GPtrArrays instead of GLists, as those are very
1802 inefficient at appends.
1804 * Renamed `create_new_leave' to `create_new_leaf'
