This patch resolves the bootstrap failure on x86_64-pc-linux-gnu.

Is this sufficiently "obvious" in stage4, or should I wait for the bootstrap

and regression testing to complete?

gcc/ChangeLog

* config/i386/i386-expand.cc (ix86_expand_cmpxchg_loop): Restore

bootstrap.

 

Cheers,

Roger

Please just bootstrap the compiler.
