+
+ For stub methods, we need to defer correcting the name
+ until we are ready to unstub the method, because the current
+ name string is used by gdb_mangle_name. The only stub methods
+ of concern here are GNU v2 operators; other methods have their
+ names correct (see caveat below).
+
+ For non-stub methods, in GNU v3, we have a complete physname.
+ Therefore we can safely correct the name now. This primarily
+ affects constructors and destructors, whose name will be
+ __comp_ctor or __comp_dtor instead of Foo or ~Foo. Cast
+ operators will also have incorrect names; for instance,
+ "operator int" will be named "operator i" (i.e. the type is
+ mangled).
+
+ For non-stub methods in GNU v2, we have no easy way to
+ know if we have a complete physname or not. For most
+ methods the result depends on the platform (if CPLUS_MARKER
+ can be `$' or `.', it will use minimal debug information, or
+ otherwise the full physname will be included).
+
+ Rather than dealing with this, we take a different approach.
+ For v3 mangled names, we can use the full physname; for v2,
+ we use cplus_demangle_opname (which is actually v2 specific),
+ because the only interesting names are all operators - once again
+ barring the caveat below. Skip this process if any method in the
+ group is a stub, to prevent our fouling up the workings of
+ gdb_mangle_name.
+
+ The caveat: GCC 2.95.x (and earlier?) put constructors and
+ destructors in the same method group. We need to split this
+ into two groups, because they should have different names.
+ So for each method group we check whether it contains both
+ routines whose physname appears to be a destructor (the physnames
+ for and destructors are always provided, due to quirks in v2
+ mangling) and routines whose physname does not appear to be a
+ destructor. If so then we break up the list into two halves.
+ Even if the constructors and destructors aren't in the same group
+ the destructor will still lack the leading tilde, so that also
+ needs to be fixed.
+
+ So, to summarize what we expect and handle here:
+
+ Given Given Real Real Action
+ method name physname physname method name
+
+ __opi [none] __opi__3Foo operator int opname
+ [now or later]
+ Foo _._3Foo _._3Foo ~Foo separate and
+ rename
