From a3747075ae478f27bf3e0643021a85fb6cdad0e3 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Tue, 12 May 2015 13:11:48 -0700 Subject: Allocate the first .plt entry space only if needed Commit dd7e64d45b317128f5fe813a8da0b13b4ad046ae may optimize out i386/x86-64 JUMP_SLOT relocation. If there is no JUMP_SLOT relocation left, we don't need to the first .plt entry. This patch allocates space for the first .plt entry only if we also reserve space for a PLT slot for JUMP_SLOT relocation. bfd/ * elf32-i386.c (elf_i386_allocate_dynrelocs): Allocate space for the first .plt entry only if needed. * elf64-x86-64.c (elf_x86_64_allocate_dynrelocs): Likewise. ld/testsuite/ * ld-i386/i386.exp: Run pltgot-1 for Linux targets. * ld-x86-64/x86-64.exp: Likewise. * ld-i386/pltgot-1.d: New file. * ld-i386/pltgot-1.s: Likewise. * ld-x86-64/pltgot-1.d: Likewise. * ld-x86-64/pltgot-1.s: Likewise. --- ld/testsuite/ld-x86-64/pltgot-1.s | 6 ++++++ 1 file changed, 6 insertions(+) create mode 100644 ld/testsuite/ld-x86-64/pltgot-1.s (limited to 'ld/testsuite/ld-x86-64/pltgot-1.s') diff --git a/ld/testsuite/ld-x86-64/pltgot-1.s b/ld/testsuite/ld-x86-64/pltgot-1.s new file mode 100644 index 0000000..2197c75 --- /dev/null +++ b/ld/testsuite/ld-x86-64/pltgot-1.s @@ -0,0 +1,6 @@ + .text + .globl plt + .type plt, @function +plt: + call *puts@GOTPCREL(%rip) + jmp puts@PLT -- cgit v1.1
