From f2c29a169242d0c564afb46ecaf160422b28bfbb Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Thu, 11 May 2017 11:26:26 -0700 Subject: [PATCH] x86-64: Rename .plt.bnd to .plt.sec Rename .plt.bnd to .plt.sec to indicate that this is used as the second PLT section. There is no change in run-time behavior. We also scan the .plt.sec section to synthesize PLT symbols. bfd/ * elf64-x86-64.c (elf_x86_64_link_hash_entry): Rename plt_bnd to plt_second. (elf_x86_64_link_hash_table): Rename plt_bnd/plt_bnd_eh_frame to plt_second/plt_second_eh_frame. (elf_x86_64_link_hash_newfunc): Updated. (elf_x86_64_allocate_dynrelocs): Likewise.
