An explicit check for address registers was not required so far since during register allocation the processing of address constraints was sufficient. However, address constraints themself do not check for REGNO_OK_FOR_{BASE,INDEX}_P. Thus, with the newly introduced late-combine pass in r15-1579-g792f97b44ffc5e we generate new insns with invalid address registers which aren't fixed up afterwards.Fixed by explicitly checking for address registers in s390_decompose_addrstyle_without_index such that those new insns are rejected. gcc/ChangeLog: target/PR115634 * config/s390/s390.cc (s390_decompose_addrstyle_without_index): Check for ADDR_REGS in s390_decompose_addrstyle_without_index.
Ok. Thanks! Andreas
