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

3171 void foo (int, foo &ia, int, foo &ib, int, foo &ic) { ia = ib = ic; }
3173 g++ produces the names:
3178 while lcc (and presumably other ARM style compilers as well) produces:
3180 foo__FiR3fooT1T2T1T2
3181 __ct__3fooFiR3fooT1T2T1T2
3183 Note that g++ bases its type numbers starting at zero and counts all
3184 previously seen types, while lucid/ARM bases its type numbers starting
3185 at one and only considers types after it has seen the 'F' character
3186 indicating the start of the function args. For lucid/ARM style, we
3187 account for this difference by discarding any previously seen types when
