Don't generate multi-byte NOPs for i686.
gas/ 2010-08-06 Quentin Neill <quentin.neill@amd.com> * config/tc-i386.c (arch_entry): Add negated bit to disambiguate flag names starting with "no". (cpu_arch): Add negated bit definitions. Add ".nop" CPU extension. (i386_align_code): Use new .cpunop bit to decide when to generate alignment using nops. (set_cpu_arch): Use negated bit instead to decide when to use cpu_flags or vs. cpu_flags_and_not. (md_parse_option): Likewise. gas/testsuite/ 2010-08-06 Quentin Neill <quentin.neill@amd.com> * gas/i386/arch-10-1.l: Add nopl instruction. * gas/i386/arch-10-2.l: Likewise. * gas/i386/arch-10-3.l: Likewise. * gas/i386/arch-10-4.l: Likewise. * gas/i386/arch-10.s: Likewise. * gas/i386/arch-10.d: Add nopl instruction, and +nopl extension flag to as flags. * gas/i386/nops-5-i686.d: Change alignment code generated for -mtune=i686. * gas/i386/nops-5.d: Change alignment code generated for .arch i686. * gas/i386/x86-64-nops-5-k8.d: Likewise. * gas/i386/x86-64-nops-5.d: Likewise. opcodes/ 2010-08-06 Quentin Neill <quentin.neill@amd.com> * i386-gen.c (cpu_flag_init): Define CpuNop extension flag, add to processor flags for PENTIUMPRO processors and later. * i386-opc.h (enum): Add CpuNop. (i386_cpu_flags): Add cpunop bit. * i386-opc.tbl: Change nop cpu_flags. * i386-init.h: Regenerated. * i386-tbl.h: Likewise.
