+ * config/tc-i386.c (cpu_arch_tune_set): New.
+ (cpu_arch_isa): Likewise.
+ (i386_align_code): Use xchg %ax,%ax for 2 byte nop. Optimize
+ nops with short or long nop sequences based on -march=/.arch
+ and -mtune=.
+ (set_cpu_arch): Set cpu_arch_isa. If cpu_arch_tune_set is 0,
+ set cpu_arch_tune and cpu_arch_tune_flags.
+ (md_parse_option): For -march=, set cpu_arch_isa and set
+ cpu_arch_tune and cpu_arch_tune_flags if cpu_arch_tune_set is
+ 0. Set cpu_arch_tune_set to 1 for -mtune=.
+ (i386_target_format): Don't set cpu_arch_tune.
