/*
|
||||
* TODO: Read this before upstreaming:
|
||||
*
|
||||
* As of Apr 2014 there is a bug regaring function type detection logic in
|
||||
* Free/Open/NetBSD implementations of __cxa_finalize().
|
||||
*
|
||||
* What it is about:
|
||||
* First of all there are two kind of atexit handlers:
|
||||
* 1) void handler(void) - this is the regular type
|
||||
* available for to user via atexit(.) function call.
|
||||
*
|
||||
* 2) void internal_handler(void*) - this is the type
|
||||
* __cxa_atexit() function expects. This handler is used
|
||||
* by C++ compiler to register static destructor calls.
|
||||
* Note that calling this function as the handler of type (1)
|
||||
* results in incorrect this pointer in static d-tors.
|
||||
*
|
||||
* What is wrong with BSD implementations:
|
||||
*
|
||||
* They use dso argument to identify the handler type. The problem
|
||||
* with it is dso is also used to identify the handlers associated
|
||||
* with particular dynamic library and allow __cxa_finalize to call correct
|
||||
* set of functions on dlclose(). And it cannot identify both.
|
||||
*
|
||||
* What is correct way to identify function type?
|
||||
*
|
||||
* Consider this:
|
||||
* 1. __cxa_finalize and __cxa_atexit are part of libc and do not have access to hidden
|
||||
* &__dso_handle.
|
||||
* 2. __cxa_atexit has only 3 arguments: function pointer, function argument, dso.
|
||||
* none of them can be reliably used to pass information about handler type.
|
||||
* 3. following http://www.codesourcery.com/cxx-abi/abi.html#dso-dtor (3.3.5.3 - B)
|
||||
* translation of user atexit -> __cxa_atexit(f, NULL, NULL) results in crashes
|
||||
* on exit() after dlclose() of a library with an atexit() call.
|
||||
*
|
||||
* One way to resolve this is to always call second form of handler, which will
|
||||
* result in storing unused argument in register/stack depending on architecture
|
||||
* and should not present any problems.
|
||||
*
|
||||
* Another way is to make them dso-local in one way or the other.
