bfd/ * elf32-arm.c (struct elf32_arm_link_hash_table): Remove no_pipeline_knowledge (elf32_arm_link_hash_table_create): Ditto. (bfd_elf32_arm_process_before_allocation): Ditto. (elf32_arm_final_link_relocate): Ditto. Remove oabi relocation handling. * bfd-in.h (bfd_elf32_arm_process_before_allocation): Update prototype. * bfd-in2.h: Regenerate. ld/ * emultempl/armelf.em: Ignore -p and -no-pipeline-knowledge.
