re PR target/26018 (Assembler errors with -march=z900 compiling glibc)
PR target/26018
* config/s390/s390.c (struct machine_function): New flag
decomposed_literal_pool_addresses_ok_p.
(s390_reorg): Set it before final stage of literal pool transforms.
(s390_decompose_address): Only accept displacements of the form
(minus (label_ref ...) (label_ref ...)) if that flag is set.
