/* In order to allow a single demangler executable to demangle strings
using various common values of CPLUS_MARKER, as well as any specific
one set at compile time, we maintain a string containing all the
commonly used ones, and check to see if the marker we are looking for
is in that string. CPLUS_MARKER is usually '$' on systems where the
assembler can deal with that. Where the assembler can't, it's usually
'.' (but on many systems '.' is used for other things). We put the
current defined CPLUS_MARKER first (which defaults to '$'), followed
by the next most common value, followed by an explicit '$' in case
the value of CPLUS_MARKER is not '$'.
We could avoid this if we could just get g++ to tell us what the actual
cplus marker character is as part of the debug information, perhaps by
ensuring that it is the character that terminates the gcc<n>_compiled
marker symbol (FIXME). */

LOCAL FUNCTION
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.
