PNE::LowerAtomiPHINode() fails because TargetInstrInfo::copyRegToReg()
doesn't support the copy of this type of register.
Most registers of this hardware are f32. These two special register of type
i32 are provided to relative index the other f32 registers. The value of
these i32 registers can only be written by a...
