From 5c3261b0e834647cf9eb555320e20871b7854f98 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Mon, 16 Oct 2017 03:49:54 -0700 Subject: ELF: Call check_relocs after opening all inputs For all ELF targers, call check_relocs after opening all inputs and garbage collection. Since the symbol resolution is known, check_relocs can be simplified. Also garbage collection doesn't need to undo what check_relocs has done for symbols which have been garbage collected. Since ELF targets never see the removed sections, gc_sweep_hook can be removed from elf_backend_data and we can avoid GOT/PLT with garbage collection now. Set link_info.check_relocs_after_open_input to TRUE for all linker targets which use ELF linker and update garbage collection tests to remove unused GOT section. ldemul_after_check_relocs is added for powerpc to support --secure-plt, --bss-plt and --sdata-got. Tested natively without regressions on i686, x86-64 and x32. Tested cross binutils on x86-64 without regressions for aarch64-linux, alpha-linux, arm-linux, bfin-elf, cr16-elf, cris-elf, crx-elf, frv-linux, hppa64-linux, hppa-linux, ia64-linux, lm32-elf, m32r-elf, m68k-linux, mcore-elf, metag-elf, microblaze-linux, mips-linux, mmix, mn10300-elf, nds32le-linux, nios2-linux, or1k-elf, powerpc64-linux, powerpc-linux, riscv32-linux, riscv64-linux, s390-linux, s390x-linux, score-elf, sh3-linux, sparc64-linux, sparc-linux, tic6x-elf, tilegx-linux, tilepro-linux, vax-linux, x86_64-mingw32 and xtensa-linux. bfd/ * elf-bfd.h (elf_backend_data): Remove gc_sweep_hook. * elf32-arm.c (elf32_arm_gc_sweep_hook): Removed.
