Subject: [PATCH] x86: Remove assembly versions of index_cpu_*/index_arch_*
Authentication-results: sourceware.org; auth=none
Reply-to: "H.J. Lu" <hjl dot tools at gmail dot com>

Since assembly versions of HAS_CPU_FEATURE and HAS_ARCH_FEATURE have
been removed,  assembly versions of index_cpu_* and index_arch_* can
also be removed.

Tested on i686 and x86-64 with and without --disable-multi-arch.

I am checking it in now.

	* sysdeps/x86/cpu-features.h [__ASSEMBLER__]
	(index_cpu_*, index_arch_*): Removed.
