With Carlos's testcase at -O2, the initial insns in the function bug are:
ldi 0,%r20
ldo 1(%r26),%r26
ldo 1(%r20),%r20
ldd 23(%r26),%r21
This appears to be a bug in the PA GO_IF_LEGITIMATE_ADDRESS macro. It should
reject 14-bit offsets for DImode loads that aren't properly aligned as ldd
doesn't support them. ldd differs from ldb/ldh/ldw in this respect. It
needs both the base and displacement aligned.
