+ protocol (via serial debug stubs)
+ * doc/gdbinv-m.m4.in, doc/gdbinv-s.m4.in: new section discussing
+ use of serial debug stubs
+
+
+ A bunch of changes mostly to improve debugging of C++ programs.
+ Specifically, nested types are supported, and the calling
+ of inferiors methods is improved.
+
+ * expression.h, c-exp.y: STRUCTOP_PTR and STRUCTOP_STRUCT
+ expression types now take an extra parameter that is used
+ for an (optional) type qualifier, as in: EXP.TYPE::NAME.
+ If there is no qualifier (as in EXP.NAME), the TYPE is NULL.
+ (Before, there was a cute but not-quote-valid re-write to
+ EXP.*(&TYPE::NAME .)
+ * parse.c (length_of_subexp, prefixify_subexp), expprint.c
+ (print_subexp), eval.c (evaluate_subexp): Handle the extra
+ operand of STRUCTOP_STRUCT and STRUCTOP_PTR.
+
+ * value.h: New macros METHOD_PTR_IS_VIRTUAL,
+ METHOD_PTR_FROM_VOFFSET, METHOD_PTR_TO_VOFFSET to partially
+ hide the implementation details of pointer-to-method objects.
+ How to tell if the pointer points to a virtual method is
+ still very dependent on the particular compiler, but this
+ should make it easier to find the places to change.
+ * eval.c (evaluate_subexp [case OP_FUNCALL]), valprint.c
+ (val_print [case TYPE_CODE_PTR]): Use the new METHOD_PTR_*
+ macros, instead of a hard-wired-in code that incorrectly
+ assumed a no-longerused representation of pointer-to-method
+ values. And otherwise fix the relevant bit-rotted code.
+
+ * valprint.c (type_print_base [case TYPE_CODE_STRUCT]):
+ If there are both fields and methods, put a space between.
+
+ * gdbtypes.h: New macro TYPE_FIELD_NESTED.
+ * symtab.C, syntab.h: New function find_nested_type()
+ searches a class recursively for a nested type.
+ * c-exp.y: Support nested type syntax: TYPE1::TYPE2.
+ This required some nasty interactions between the lexer
+ and the parser (surprise, surprise), using the current_type
+ global variable (see comment above its declaration),
+ and the new function find_nested_type().
+ * expprint.c (print_subexp), valprint.c (val_print_fields,
+ type_print_base [case TYPE_CODE_STRUCT]): Support nested types.
+ * stabsread.c (read_struct_type): Recognize types fields
+ nested in classes.
+
+ * gdbtypes.c, symtab.h: New functions check_struct,
+ check_union, and check_enum (factored out from lookup_struct,
+ lookup_union, lookup_enum).
+ * c-exp.y: Support 'enum Foo::Bar' syntax as just the same
+ as 'Foo::Bar' followed by a call to check_enum. Similarly
+ for struct and union.
+
+ * stabsread.c (read_struct_type): Fix bug in handling of
+ GNU C++ anonymous type (indicated by CPLUS_MARKER followed
+ by '_'). (It used to prematurely exit the loop reading in
+ the fields, so it would think it should start reading
+ methods while still in the fields. This could crash gdb
+ given a gcc that can emit nested type information.)
+
+ * valops.c (search_struct_method): Pass 'this' value by
+ reference instead of by value. This provides a more
+ consistent interface through a recursive search where the
+ "bottom" functions may need to adjust offsets (due to multiple
+ inheritance).
+ * valops.c, value.h, values.c: Pass extra parameters to
+ value_fn_field and value_virtual_fn_field so we can
+ correctly adjust offset for multiple inheritance.
+ * eval.c (evaluate_subexp [case OP_FUNCALL]): Simplify
+ virtual function calls by using value_virtual_fn_field().
+ * values.c: New function baseclass_offset, derived from
+ baseclass_addr (which perhaps can be made obsolete?).
+ It returns an offset rather than an address. This is a
+ cleaner interface since it doesn't mess around allocating
+ new values.
+ * valops.c (search_struct_method): Use baseclass_offset
+ rather than baseclass_addr.
+
+ * symfile.h: Declaration of set_demangling_style() moved
+ here from demangle.h (which is now in ../include).
+ * i386-xdep.c: Update comment.
+ * utils.c (strcmp_iw): Add a hack to allow "FOO(ARGS)" to
+ match "FOO". This allows 'break Foo' to work when Foo is
+ a mangled C++ function. (See comment before function.)
+
+
+ * symtab.c (completion_list_add_symbol): restructured to optimize
+ for time. First clip names that cannot match. Then clip any
+ names we've already considered. Drop a redundant strncpy. Drop
+ a redundant malloc and associated free for demangled names.
+

+ value to keep braindamaged HP/Apollo compiler happy.
+
+
+ * utils.c (strcmp_iw): Add a hack to allow "FOO(ARGS)" to

+
+ * configure.in: Map unrecognized sun 68k's, sun sparcs, into

+ in production on Sun-4.

+ target definitions for embedded with and without underlines on
+ identifiers. FIXME -- this ought to be known by BFD instead.
+
+ * tm-sparc.h, tm-sun2.h, tm-sun3.h: Delete NAMES_HAVE_UNDERSCORE:
+ not a parameter of the CPU, but of the development environment.
+ * tm-es1800.h, tm-sunos.h, tm-vx68.h: Add NAMES_HAVE_UNDERSCORE.
+
+
+ * breakpoint.c (breakpoint_re_set): Avoid setting source symtab

+
+
+ * dwarfread.c (cu_language): New local variable to record
+ language for current compilation unit being processed.

+ * dwarfread.c (add_partial_symbol): Combine TAG_enumeration_type
+ case with class, struct, and union type cases, now that they are
+ the same. Remove tests for non-NULL name attributes, now done
+ by callers.
+ * gdbtypes.h (TYPE_CODE_CLASS): Add type for C++ classes, but
+ treat as alias for TYPE_CODE_STRUCT for now.
+
+
+ * Makefile.in: map "gdb" through program_transform_name when
+ installing.
+
+
+ * {i386-tdep.c, m68k-tdep.c, mips-tdep.c, sparc-tdep.c}
+ (supply_gregset, fill_gregset, supply_fpregset, fill_fpregset):
+ Use "regi" for local indexing through register numbers, reserving
+ "regno" for the name of a specific register passed as an input
+ parameter. Fix bug propagated through all versions that sometimes
+ used regno as an index when it should have been regi, thus using
+ -1 as an index in some cases.
+
+
+ * cplus-dem.c, demangle.h: Moved to ../libiberty and ../include,
+ respectively, so same demangler can be used by other programs.
+ * Makefile.in: Remove demangler stuff.
+ * Makefile.in (depend): Pass -I../readline (needed for main.c).

+ for callers.
+
+ * vx-share/README, nindy-share/README: New files describing
+ how these directories' code is shared, and with whom.

+ config/{altosgas.mh, i386v-g.mh, i386v32-g.mh}: Remove.
+
+
+ * cplus-dem.c: Reorder args to most local functions to make them
+ follow the consistent pattern of struct work_stuff pointer first,
+ followed by pointer into string being demangled, followed by
+ pointer to the string where the result is being stored, followed
+ by other args. Also generally replace most variables of name
+ "type" with "mangled" for consistency. They all pointed to the
+ same string but half were one name and half the other.

+ * cplus-dem.c (demangle_qualified): Rewrite to clean up and allow
+ use whenever a qualified name is being demangled.
