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

3452 If *type does not point at a string of digits, return zero.
3454 If *type points at a string of digits followed by an

3460 value as an integer, leave *type pointing after that digit,
3463 The excuse for this odd behavior: in the ARM and HP demangling
3464 styles, a type can be followed by a repeat count of the form
3467 `x' is a single digit specifying how many additional copies
3468 of the type to append to the argument list, and
3470 `y' is one or more digits, specifying the zero-based index of
3471 the first repeated argument in the list. Yes, as you're
3472 unmangling the name you can figure this out yourself, but
3475 So, for example, in `bar__3fooFPiN51', the first argument is a
3476 pointer to an integer (`Pi'), and then the next five arguments
