Since it is incorrect to convert bnd call *foo@GOTPCREL(%rip) to bnd nop call foo this patch removes the "-z prefix-nop" option from x86 linker. * emulparams/call_nop.sh: Remove -z prefix-nop. * ld.texinfo: Likewise. * testsuite/ld-i386/call3c.d: Check for linker error. * testsuite/ld-x86-64/call1c.d: Likewise.
