This patch adds support for ARM PLT entries that support a full 32-bit offset range.
Enabled via the use of a new linker command line option: --long-plt. * bfd-in.h: Add export of bfd_elf32_arm_use_long_plt. * bfd-in2.h: Regenerate. * elf32-arm.c (elf32_arm_plt_entry_long): New array. (elf32_arm_link_hash_table_create): Set plt_entry_size to 16 if using long PLT entries. (bfd_elf32_arm_use_long_plt): New function. (elf32_arm_populate_plt_entry): Add support for long PLT entries. * emultempl/armelf.em (OPTION_LONG_PLT): Define. (PARSE_AND_LIST_LONGOPTS): Add long-plt. (PARSE_AND_LIST_OPTIONS): Likewise. (PARSE_AND_LIST_ARGS_CASES): Handle long-plt. * ld.texinfo: Document --long-plt. * ld-arm/long-plt-format.s: New test case. * ld-arm/long-plt-format.d: Expected disassembly. * ld-arm/arm-elf.exp: Run the new test.
