Confirmed. 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).
