| the value of CPLUS_MARKER is not '$'. |

| 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. */ |

| 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. |

| DESCRIPTION |
| |
| Demangle a qualified name, such as "Q25Outer5Inner" which is |
| the mangled form of "Outer::Inner". The demangled output is |
| prepended or appended to the result string according to the |
| state of the append flag. |
| |
| If isfuncname is nonzero, then the qualified name we are building |
| is going to be used as a member function name, so if it is a |
| constructor or destructor function, append an appropriate |
| constructor or destructor name. I.E. for the above example, |
| the result for use as a constructor is "Outer::Inner::Inner" |
| and the result for use as a destructor is "Outer::Inner::~Inner". |
| |
| BUGS |
| |
| Numeric conversion is ASCII dependent (FIXME). |

| 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. |
| |
| So, for example, in `bar__3fooFPiN51', the first argument is a |
| pointer to an integer (`Pi'), and then the next five arguments |
| are the same (`N5'), and the first repeat is the function's |
| second argument (`1'). |

| |
| 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 |

| Symbols are composed of uppercase and lowercase letters, decimal |
| digits, dollar symbol, period (.), ampersand (&), pound sign(#) and |
| underscore (_). A symbol can begin with a letter, digit underscore or |
