Hi, Many thanks for that. I switched on RTTI and did get some link once sections as shown in the object file. They were not quite named the way I expected though. For example I coded in a C++ file a simple class, MyClass, that consisted of just one constructor MyClass() defined inline. In the object file I got. _ZN7MyClassC1Ev which was shown as LINK_ONCE_DISCARD and also a .text._ZN7MyClassC1Ev section. I did not find any sections that used the prefix .gnu.linkonce.t., for example I would have expected to see a section named .gnu.linkonce.t._ZN7MyClassC1Ev I am using V4.1.1 of the GCC toolset if that is significant. Are these results as would be expected or should I have indeed got some .gnu.linkonce.t. prefixed sections?
