Module: libav Branch: release/0.8 Commit: e287201c77dc7a7a9759d56d8f48ae719b7e69a9
Author: Diego Biurrun <[email protected]> Committer: Diego Biurrun <[email protected]> Date: Sun Nov 11 22:41:46 2012 +0100 x86: Require an assembler able to cope with AVX instructions All modern assemblers have this capability. Older NASM versions that lack the capability produce code that crashes at runtime, so it's better to error out during the build process instead.
