From 99b99831e467ad97336103e48f22e9c7956a51ef Mon Sep 17 00:00:00 2001 From: Yunqing Wang Date: Wed, 14 Jan 2015 15:51:56 -0800 Subject: [PATCH] Align thread data in vp9_ethread On some platforms, such as 32bit Windows and 32bit Mac, the allocated memory isn't aligned automatically. The thread data is aligned to ensure the correct access in SIMD code.
