Seems to be an issue with alignment calculation in
aarch64_classify_address.
for rtl of the form (lo_sum:DI (reg/f:DI 132)
(symbol_ref:DI ("*.LANCHOR4") [flags 0x182])) we are currently
calculating align of 8bits and due to this the following statement
returns false. This causes output_addr_const (in gcc/final.c) to fail.
return ((INTVAL (offs) & (ref_size - 1)) == 0
&& ((align / BITS_PER_UNIT) & (ref_size - 1)) == 0);
AFIK, align of 8bits is not correct here.
