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 | |
0897ed3b ST |
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. | |
