|

|

To ensure global C++ constructors in linked libraries are run before global
|
||||
C++ constructors from the current module, there is additional symbol scanning
|

logic in collect2.
|
||||
|
||||
The global initialiser/finaliser functions are named __GLOBAL_AIXI_{libname}
|
||||
and __GLOBAL_AIXD_{libname} and are exported from each shared library.
|
||||
|
||||
collect2 will detect these symbols when they exist in shared libraries that
|
||||
the current program is being linked against. All such initiliser functions
|
||||
will be called prior to the constructors of the current program, and
|
||||
finaliser functions called after destructors.
|
||||
|
||||
Reference counting generated by collect2 will ensure that constructors are
|
||||
only invoked once in the case of multiple dependencies on a library.
|
||||
|
||||
-binitfini is still used in parallel to this solution.
|
||||
This handles the case where a library is loaded through dlopen(), and also
|
||||
handles the option -blazy.
