From e604ee39cff121fdb2c6946a230bc2374929b35b Mon Sep 17 00:00:00 2001 From: Vadim Yanitskiy Date: Mon, 1 May 2017 16:44:02 +0700 Subject: core/conv: strip unused memalign() call The alligned memory allocation is only required for SSE, which is currently unsupported. Moreover, it's better to use dedicated _mm_malloc() and _mm_free() from xmmintrin.h instead, which are introduced by Intel specifically for SIMD computations.
