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