319 2002-05-21 Martin Baulig <martin@gnome.org>
321 Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
322 file for all assemblies. Currently, the JIT doesn't put all methods
323 from a single assembly into a continuous region of memory. We were
324 previously creating valid DWARF 2 files for this, but unfortunately
325 GDB's symbol tables get messed up when it reads more than one such file.
327 * debug-private.h (AssemblyDebugInfo): Moved `f', `producer_name',

424 instruction, not to the instruction after the call. This fixes the

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

820 2002-03-28 Dietmar Maurer <dietmar@ximian.com>

843 * debug-stabs.c (write_method_stabs): Don't generate method lines if
844 we don't have line number information. Use `minfo->method_info.this_offset'
845 instead of hardcoding 8.

870 * debug.c (mono_debug_add_method): Include the `this' offset in
871 the `minfo->method_info.param_offsets' array.
873 2002-03-23 Martin Baulig <martin@gnome.org>
875 * x86.brg (lreg: CONV_I8 (reg)): X86_XOR modifies the flags, so we need
876 to do it before the X86_CMP.
877 (reg: CLT (lreg, lreg)): Use correct x86_branch8() targets.
878 (reg: CLT (lreg, lreg)): Likewise.

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

950 * debug.c (mono_debug_get_type): Recursively call this for all function members
952 (mono_debug_add_method): Don't mangle function names, this must be done by the
953 debugger backend if the debugging format needs mangled names.
955 * debug-dwarf2.c: Improved support for classes, added member functions.
957 2002-03-16 Martin Baulig <martin@gnome.org>

962 * debug-dwarf2.c: Added basic support for classes. Set source language to C++
963 since GDB doesn't like Java very much.
965 2002-03-16 Martin Baulig <martin@gnome.org>
967 * debug-dwarf2.c: Added support for enums.
969 2002-03-15 Martin Baulig <martin@gnome.org>

990 * debug.c (MonoDebugFormat): New public enums specifying which debugging
992 (mono_debug_open_file): Added MonoDebugFormat argument.
993 (mono_debug_make_symbols): Don't take an argument to make it easier to call
994 this function from GDB. It's now safe to call this function multiple times;
995 it'll always write a complete debugging file.
997 * debug.c: Splitted this file into a general part which remains in this file
998 and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.
999 All public functions now call a corresponding format specific function.
1001 * debug.c: The following changes are private to debug.c:
1002 (AssemblyDebugInfo, MonoDebugHandle): Moved declarations to debug-private.h.
1003 (record_line_number, debug_generate_method_lines): New private functions.
1004 (mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now
1005 calls a debugging-format-specific function (mono_debug_open_assembly_stabs or
1006 mono_debug_open_assembly_dwarf2).
1007 (mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
1008 now safe to call this function multiple times.
1009 (mono_debug_get_type): New public function. This takes a `MonoClass *' and
1010 returns an unique index for this type. It's used to ensure that we only write
1011 each class once to the debugging file.
1012 (mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
1013 data structure, but don't directly write to the debugging file. This is done
1014 later from mono_debug_write_assembly().
1016 * jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
1017 debugging output. Call mono_debug_close() on cleanup if necessary.
1019 2002-03-14 Martin Baulig <martin@gnome.org>
1021 * debug-private.h: New private header file.
1023 * debug-stabs.c: Added the stabs type generation stuff which was
1024 previously in debug.c.
1026 * debug-dwarf.c: Started to implement type support. We're currently
1027 only writing this most basic types to the dwarf file, but this will
1030 2002-03-13 Martin Baulig <martin@gnome.org>
1032 * debug-stabs.c, debug-dwarf2.c: New files containing my new
1033 debugging code. They're now in CVS, but not yet used anywhere.
1035 2002-03-11 Dietmar Maurer <dietmar@ximian.com>
1037 * emit-x86.c (mono_delegate_ctor): use C impl. instead of x86_*
1038 macros, included new delegate code from Daniel Stodden.
1041 Mon Mar 11 14:47:21 CET 2002 Paolo Molaro <lupus@ximian.com>
1043 * jit.c: verify that corlib and runtime are in sync.
1045 Mon Mar 11 11:30:56 CET 2002 Paolo Molaro <lupus@ximian.com>
1047 * emit-x86.c, jit.c: use the debug-helpers facilities to
1048 describe and match a method when debugging.
1050 2002-03-10 Martin Baulig <martin@gnome.org>
1052 * emit-x86.c (arch_compile_method): When emitting stabs debugging
1053 output, put a nop instruction at the start of all functions so that
1054 the adresses won't change when using --debug.
1056 * debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
1057 the bytecode area, stabs needs a line number in the .il file. Use the
1058 new info->moffsets to get the line number.
1059 (AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
1060 `moffsets' is an array of `total_lines' fields (total number of lines
1061 in the .il file); for each line in the .il field, this array contains
1062 the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
1063 of a method and 0 otherwise.
1064 (debug_load_method_lines): Read the whole .il file and initialize the
1065 info->moffsets field.
1067 2002-03-09 Martin Baulig <martin@gnome.org>
1069 * x86.brg (DIV_UN): Clear EDX before performing the division and remove
1070 the unnecessary CDQ instruction.
1072 2002-03-07 Dietmar Maurer <dietmar@ximian.com>
1074 * jit.c (mono_analyze_stack): only load addresses of value types
1075 on the runtime stack.
1077 2002-03-07 Duncan Mak <duncan@ximian.com>
1079 * Makefile.am: A small patch fixing errors in vpath-based builds
1080 (make clean failing to rerun monoburg due to BUILT_SOURCES usage),
1081 committed for Daniel Stodden <stodden@in.tum.de>.

1144 Tue Feb 26 11:56:03 CET 2002 Paolo Molaro <lupus@ximian.com>
1146 * x86.brg: optimize cmp reg,0 -> test reg.
1148 Sun Feb 24 13:58:34 CET 2002 Paolo Molaro <lupus@ximian.com>

1151 and the --stats command line option to print them.
1152 Fixed memory leak in arch_compile_method () when a method's code is

1748 * x86.brg: use the right offsets to access local variables

1765 * x86.brg: Use Unix assembly syntax.
1767 * emit-x86.c: support code, should be moved
1769 * testjit.c: Use GPtrArrays instead of GLists, as those are very
1770 inefficient at appends.
