+

+
+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.

+ __ct__3fooFiR3fooT1T2T1T2
+
+ Note that g++ bases it's type numbers starting at zero and counts all
+ previously seen types, while lucid/ARM bases it's 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
