* elf32-xtensa.c (extend_ebb_bounds_forward): Use renamed XTENSA_PROP_NO_TRANSFORM flag instead of XTENSA_PROP_INSN_NO_TRANSFORM. (extend_ebb_bounds_backward, compute_text_actions): Likewise. (compute_ebb_proposed_actions, coalesce_shared_literal): Likewise. (xtensa_get_property_predef_flags): Likewise. (compute_removed_literals): Pass new arguments to is_removable_literal. (is_removable_literal): Add sec, prop_table and ptblsize arguments. Do not remove literal if the NO_TRANSFORM property flag is set. gas/ * config/tc-xtensa.c (XTENSA_PROP_INSN_NO_TRANSFORM): Renamed to... (XTENSA_PROP_NO_TRANSFORM): ...this. (frag_flags_struct): Move is_no_transform out of the insn sub-struct. (xtensa_mark_frags_for_org): New. (xtensa_handle_align): Set RELAX_ORG frag subtype for rs_org. (xtensa_post_relax_hook): Call xtensa_mark_frags_for_org. (get_frag_property_flags): Adjust reference to is_no_transform flag. (xtensa_frag_flags_combinable): Likewise. (frag_flags_to_number): Likewise. Use XTENSA_PROP_NO_TRANSFORM. * config/tc-xtensa.h (xtensa_relax_statesE): Add RELAX_ORG. include/elf/ * xtensa.h (XTENSA_PROP_INSN_NO_TRANSFORM): Renamed to...
