Re: [PATCH] Remove Prefer_SSE_for_memop on x64

Hello,
As I asked in
http://www.sourceware.org/ml/libc-alpha/2013-02/msg00203.html
nobody objected to keep non-sse memset on x64.

This patch removes that implementation and flag Prefer_SSE_for_memop
which is always set and only choose sse memset over nonsse one.

2013-02-14 OndÅej BÃlka <neleai@seznam.cz>

* sysdeps/x86_64/memset.S: Always define bcopy.

I suggest: Remove USE_MULTIARCH conditional for definining bcopy.

* sysdeps/x86_64/multiarch/Makefile: Update.

Which variable are you changing - and how?


	* sysdeps/x86_64/multiarch/ifunc-impl-list.c: Update.
	* sysdeps/x86_64/multiarch/init-arch.c: Remove Prefer_SSE_for_memop.

The two entries above miss the function changed. Replace Update with a proper description.


* sysdeps/x86_64/multiarch/init-arch.h: Likewise.

Mention every single define your remove.


	* sysdeps/x86_64/multiarch/bzero.S: Remove.
	* sysdeps/x86_64/multiarch/memset-x86-64.S: Likewise.
	* sysdeps/x86_64/multiarch/memset.S: Likewise.
	* sysdeps/x86_64/multiarch/memset_chk.S: Likewise.


The patch itself is fine, please send an updated changelog for review,


thanks,
Andreas
