Lynn Boger	fbbbdbdd6f	sha3: revert alignment optimization on ppc64 ... A previous fix to improve performance based on alignment to sha3 was made in both ppc64le and ppc64, when it should have only applied to ppc64le. This changes the build tags so it is only done for ppc64le. Fixes golang/go#15392 Change-Id: Idf32a0370f3c76fc2b54a2897a668acbae5d43c5 Reviewed-on: https://go-review.googlesource.com/22323 Reviewed-by: Brad Fitzpatrick <bradfitz@golang.org>	2016-04-20 21:40:36 +00:00
Lynn Boger	c197bcf24c	golang/x/crypto/sha3: use better alignment ... Change the build tags for xor.go and xor_unaligned.go to perform better on ppc64/ppc64le.
