x86: Generate PLT relocations for -z now
This patch partially reverses: commit25070364b0Author: H.J. Lu <hjl.tools@gmail.com> Date: Sat May 16 07:00:21 2015 -0700 Don't generate PLT relocations for now binding to support LD_AUDIT and LD_PROFILE with -z now. If there is an existing GOT relocation, it is still used to avoid PLT relocation against the same function symbol. bfd/ * elf32-i386.c (elf_i386_allocate_dynrelocs): Partially revert commit25070364b0. * elf64-x86-64.c (elf_x86_64_allocate_dynrelocs): Likewse. ld/ * testsuite/ld-i386/plt-pic2.dd: Updated. * testsuite/ld-i386/plt2.dd: Likewise. * testsuite/ld-i386/plt2.rd: Likewise. * testsuite/ld-i386/pr17689now.rd: Likewise. * testsuite/ld-ifunc/ifunc-16-i386-now.d: Likewise. * testsuite/ld-ifunc/ifunc-16-x86-64-now.d: Likewise. * testsuite/ld-ifunc/pr17154-i386-now.d: Likewise. * testsuite/ld-ifunc/pr17154-x86-64-now.d: Likewise. * testsuite/ld-x86-64/bnd-branch-1-now.d: Likewise. * testsuite/ld-x86-64/bnd-ifunc-2-now.d: Likewise. * testsuite/ld-x86-64/bnd-plt-1-now.d: Likewise. * testsuite/ld-x86-64/plt2.dd: Likewise. * testsuite/ld-x86-64/plt2.rd: Likewise. * testsuite/ld-x86-64/pr17689now.rd: Likewise. * testsuite/ld-x86-64/pr21038b-now.d: Likewise. * testsuite/ld-x86-64/pr21038c-now.d: Likewise.
