(RELOC_SECTION, RELOC_SIZE, SWAP_RELOC_IN, SWAP_RELOC_OUT): New macros. (elf32_arm_vxworks_bed): Add forward declaration. (elf32_arm_howto_table_1): Fix the masks for R_ASM_ABS12. (elf32_arm_vxworks_exec_plt0_entry): New table. (elf32_arm_vxworks_exec_plt_entry): Likewise. (elf32_arm_vxworks_shared_plt_entry): Likewise. (elf32_arm_link_hash_table): Add vxworks_p and srelplt2 fields. (reloc_section_p): New function. (create_got_section): Use RELOC_SECTION. (elf32_arm_create_dynamic_sections): Likewise. Call elf_vxworks_create_dynamic_sections for VxWorks targets. Choose between the two possible values of plt_header_size and plt_entry_size. (elf32_arm_link_hash_table_create): Initialize vxworks_p and srelplt2. (elf32_arm_abs12_reloc): New function. (elf32_arm_final_link_relocate): Call it. Allow the creation of dynamic R_ARM_ABS12 relocs on VxWorks. Use reloc_section_p, RELOC_SIZE, SWAP_RELOC_OUT and RELOC_SECTION. Initialize the r_addend fields of relocs. On rela targets, skip any code that adjusts in-place addends. When using _bfd_link_final_relocate to perform a final relocation, pass rel->r_addend as the addend argument. (elf32_arm_merge_private_bfd_data): If one of the bfds is a VxWorks object, ignore flags that are not standard on VxWorks. (elf32_arm_check_relocs): Allow the creation of dynamic R_ARM_ABS12 relocs on VxWorks. Use reloc_section_p. (elf32_arm_adjust_dynamic_symbol): Use RELOC_SECTION and RELOC_SIZE. (allocate_dynrelocs): Use RELOC_SIZE. Account for the size of .rela.plt.unloaded relocs on VxWorks targets. (elf32_arm_size_dynamic_sections): Use RELOC_SIZE. Check for .rela.plt.unloaded as well as .rel(a).plt. Add DT_RELA* tags instead of DT_REL* tags on RELA targets. (elf32_arm_finish_dynamic_symbol): Use RELOC_SECTION, RELOC_SIZE and SWAP_RELOC_OUT. Initialize r_addend fields. Handle VxWorks PLT entries. Do not make _GLOBAL_OFFSET_TABLE_ absolute on VxWorks. (elf32_arm_finish_dynamic_sections): Use RELOC_SECTION, RELOC_SIZE and SWAP_RELOC_OUT. Initialize r_addend fields. Handle DT_RELASZ like DT_RELSZ. Handle the VxWorks form of initial PLT entry. Correct the .rela.plt.unreloaded symbol indexes. (elf32_arm_output_symbol_hook): Call the VxWorks version of this hook on VxWorks targets. (elf32_arm_vxworks_link_hash_table_create): Set vxworks_p to true. Minor formatting tweak.
