Re: [FFmpeg-devel] [PATCH] Fix missing used attribute for inline assembly variables

It's needed for the same reason the used attribute was already added to the "static const" variables. For those, when building with just -O2, they could be removed by optimization since they had local (file) scope, and we couldn't see the uses in the inline assembly (without the used attribute).
