* elf32-sh.c (elf_sh_plt0_entry_be, elf_sh_plt0_entry_le): Copy
contents of .got.plt[2] to tr0, not address of .got.plt. (sh_elf_finish_dynamic_symbol): Do not apply GOT_BIAS when patching absolute plt entry. For shmedia plt entry, set bottom bit of branch to plt0 as this is a branch to an shmedia instruction. * elf64-sh64.c (elf_sh64_plt0_entry_be, elf_sh64_plt0_entry_le): Copy contents of .got.plt[2] to tr0, not address of .got.plt. (elf_sh64_plt_entry_be, elf_sh64_plt_entry_le): Use ptrel to branch to plt0. (sh64_elf64_finish_dynamic_symbol): Do not apply GOT_BIAS when patching absolute plt entry. For shmedia plt entry, branch to plt0 is now ptrel, so use relative offset. Set bottom bit of branch target as it is a branch to an shmedia instruction.
