+ * emultempl/armelf.em (..._parse_args): New function: Parse
+ command line option. Accept arm-elf specific command line option
+ '-p' or '--no-pipeline-knowledge'.
+ (..._list_options): New function: Describe the new command line
+ option.
+ (..._before_allocation): Pass the value of the new variable
+ no_pipeline_knowledge to bfd_elf32_arm_process_before_allocation.
+
+ * emultemp/armelf_oabi.em (..._before_allocation): Pass zero as
+ the third parameter to bfd_elf32_arm_process_before_allocation.
