The problem occurs in fwprop1 where instructions corresponding to the following assembly addis r2,r31,ha16(_A.1.1600-L1$pb) la r9,lo16(_A.1.1600-L1$pb)(r2) ld r2,0(r9) are combined to addis r2,r31,ha16(_A.1.1600-L1$pb) la r9,lo16(_A.1.1600-L1$pb)(r2) ld r2,lo16(_A.1.1600-L1$pb)(r2) ie. the offset is propagated into the memory load. This ought to give you an error at assembly or link time. If not, you have a bad assembler or linker.. movdi_low is the culprit, I think. It should require a suitably aligned offset (operand 2).
