2006-06-30 H.J. Lu <hongjiu.lu@intel.com> * elf32-i386.c (elf_i386_relocate_section): Use xchg %ax,%ax instead of 2 nops. * elf64-x86-64.c (elf64_x86_64_relocate_section): Likewise. (elf64_x86_64_plt0_entry): Use nopl 0(%rax) instead of 4 nops. ld/testsuite/ 2006-06-30 H.J. Lu <hongjiu.lu@intel.com> * ld-i386/tlsbindesc.dd: Updated to expect xchg %ax,%ax instead of 2 nops. * ld-i386/tlsdesc.dd: Likewise. * ld-i386/tlsgdesc.dd: Likewise. * ld-x86-64/tlsbindesc.dd: Likewise. * ld-x86-64/tlsdesc.dd: Likewise. * ld-x86-64/tlsdesc.pd: Likewise. * ld-x86-64/tlsgdesc.dd: Likewise.
