Read the original source →FEAT_CPA (Checked Pointer Arithmetic) adds pointer arithmetic instructions that, on overflow out of the address bits, force bit 54 to disagree with bit 55. This makes the result non-canonical so it faults when dereferenced. For readable decompilation these are lifted as if the instructions are supported but enforcement is disabled (i.e., as if the CPU suppo…
