When there are both PLT and GOT references to the same function symbol, linker combines GOTPLT and GOT slots into a single GOT slot and create an entry in .plt.got section for PLT access via the GOT slot. This patch adds unwind info for .plt.got section. bfd/ PR ld/20830 * elf32-i386.c (elf_i386_eh_frame_plt_got): New. (PLT_GOT_FDE_LENGTH): Likewise.
