// The goal of this program is to verify if identical code folding

// in safe mode correctly folds only ctors and dtors. kept_func_1 must

// not be folded into kept_func_2 other than for X86 (32 and 64 bit)

// which can use relocation types to determine if function pointers are

// taken.  kept_func_3 should never be folded as its pointer is taken.

// The ctor and dtor of class A must be folded.
