23// The goal of this program is to verify if identical code folding
24// in safe mode correctly folds only ctors and dtors. kept_func_1 must
25// not be folded into kept_func_2 other than for X86 (32 and 64 bit)
26// which can use relocation types to determine if function pointers are
27// taken.  kept_func_3 should never be folded as its pointer is taken.
28// The ctor and dtor of class A must be folded.
