Agreed, and especially true for the more unusual demanglings like Lucid
or EDG.
On the gdb side perhaps we can get rid of "demangle-style" now. It
probably hasn't worked properly in years, and after this it would be
guaranteed not to.
So, here's the patch to tear out the old code, which passes the GCC
regression testsuite. I also tried building binutils/gdb with it, and
both will need to remove code that calls cplus_mangle_opname for dealing
with the old mangling scheme.

-
- demangle_signature -- demangle the signature part of a mangled name
-
-SYNOPSIS
-
- static int
- demangle_signature (struct work_stuff *work, const char **mangled,
- string *declp);
-
-DESCRIPTION
-
- Consume and demangle the signature portion of the mangled name.
-
- DECLP is the string where demangled output is being built. At
- entry it contains the demangled root name from the mangled name
- prefix. I.E. either a demangled operator name or the root function
- name. In some special cases, it may contain nothing.
-
- *MANGLED points to the current unconsumed location in the mangled
- name. As tokens are consumed and demangling is performed, the
- pointer is updated to continuously point at the next token to
- be consumed.
-
- Demangling GNU style mangled names is nasty because there is no
- explicit token that marks the start of the outermost function
- argument list. */

-LOCAL FUNCTION
-
- demangle_class -- demangle a mangled class sequence
-
-SYNOPSIS
-
- static int
- demangle_class (struct work_stuff *work, const char **mangled,
- strint *declp)
-
-DESCRIPTION
-
- DECLP points to the buffer into which demangling is being done.
-
- *MANGLED points to the current token to be demangled. On input,
- it points to a mangled class (I.E. "3foo", "13verylongclass", etc.)
- On exit, it points to the next token after the mangled class on
- success, or the first unconsumed token on failure.
-
- If the CONSTRUCTOR or DESTRUCTOR flags are set in WORK, then
- we are demangling a constructor or destructor. In this case
- we prepend "class::class" or "class::~class" to DECLP.
-
- Otherwise, we prepend "class::" to the current DECLP.
-
- Reset the constructor/destructor flags once they have been
- "consumed". This allows demangle_class to be called later during
- the same demangling, to do normal class demangling.
-
- Returns 1 if demangling is successful, 0 otherwise.

-SYNOPSIS
-
- static int

- string *declp);
-
-DESCRIPTION
-
- Consume and demangle the prefix of the mangled name.
- While processing the function name root, arrange to call
- demangle_signature if the root is ambiguous.
-
- DECLP points to the string buffer into which demangled output is
- placed. On entry, the buffer is empty. On exit it contains
- the root function name, the demangled operator name, or in some
- special cases either nothing or the completely demangled result.
-
- MANGLED points to the current pointer into the mangled name. As each
- token of the mangled name is consumed, it is updated. Upon entry
- the current mangled name pointer points to the first character of
- the mangled name. Upon exit, it should point to the first character
- of the signature if demangling was successful, or to the first
- unconsumed character if demangling of the prefix was unsuccessful.
-
- Returns 1 on success, 0 otherwise.

-LOCAL FUNCTION
-
- get_count -- convert an ascii count to integer, consuming tokens
-
-SYNOPSIS
-
- static int
- get_count (const char **type, int *count)
-
-DESCRIPTION
-
- Assume that *type points at a count in a mangled name; set
- *count to its value, and set *type to the next character after
- the count. There are some weird rules in effect here.
-
- If *type does not point at a string of digits, return zero.
-
- If *type points at a string of digits followed by an
- underscore, set *count to their value as an integer, advance
- *type to point *after the underscore, and return 1.
-
- If *type points at a string of digits not followed by an
- underscore, consume only the first digit. Set *count to its
- value as an integer, leave *type pointing after that digit,
- and return 1.
-
- The excuse for this odd behavior: in the ARM and HP demangling
- styles, a type can be followed by a repeat count of the form
- `Nxy', where:
-
- `x' is a single digit specifying how many additional copies
- of the type to append to the argument list, and
-
- `y' is one or more digits, specifying the zero-based index of
- the first repeated argument in the list. Yes, as you're
- unmangling the name you can figure this out yourself, but
- it's there anyway.

-/* Process the argument list part of the signature, after any class spec
- has been consumed, as well as the first 'F' character (if any). For
- example:
-
- "__als__3fooRT0" => process "RT0"
- "complexfunc5__FPFPc_PFl_i" => process "PFPc_PFl_i"
-
- DECLP must be already initialised, usually non-empty. It won't be freed
- on failure.
-
- Note that g++ differs significantly from ARM and lucid style mangling
- with regards to references to previously seen types. For example, given
- the source fragment:
-
- class foo {
- public:
- foo::foo (int, foo &ia, int, foo &ib, int, foo &ic);
- };
-
- foo::foo (int, foo &ia, int, foo &ib, int, foo &ic) { ia = ib = ic; }
- void foo (int, foo &ia, int, foo &ib, int, foo &ic) { ia = ib = ic; }
-
- g++ produces the names:
-
- __3fooiRT0iT2iT2
- foo__FiR3fooiT1iT1
-
- while lcc (and presumably other ARM style compilers as well) produces:
-
- foo__FiR3fooT1T2T1T2
- __ct__3fooFiR3fooT1T2T1T2
-
- Note that g++ bases its type numbers starting at zero and counts all
- previously seen types, while lucid/ARM bases its type numbers starting
- at one and only considers types after it has seen the 'F' character
- indicating the start of the function args. For lucid/ARM style, we
- account for this difference by discarding any previously seen types when
- we see the 'F' character, and subtracting one from the type number
- reference.

-# This is generated by an EDG compiler (kcc 4.0). To demangle it

-# starting with 41THandle.... However, lacking a spec for EDG
-# demangling, it's hard to implement this.

-# In the meantime, this symbol can be successfully demangled in GNU
