Many warnings for dead-calls are emitted with patch on call to
operator new in libsupc++/eh_alloc.cc, which I am not sure are correct
or false positives, for instance:
/home/prathamesh.kulkarni/gcc-svn/trunk/libstdc++-v3/libsupc++/eh_alloc.cc:170:22:
warning: Call from void* {anonymous}::pool::allocate(std::size_t) to
void* operator new(std::size_t, void*) has no effect [-Wunused-value]
new (f) free_entry;
^
It appears to me new() is defined as follows in libsupc++/new:
// Default placement versions of operator new.
inline void* operator new(std::size_t, void* __p) _GLIBCXX_USE_NOEXCEPT
{ return __p; }
So could it be considered as a dead call since new() doesn't have side-effect
and it's return value is not assigned to any variable
or is the warning wrong for the above call ?
Thanks,
