[FFmpeg-devel] [PATCH 1/2] aarch64: Use ret x<n> instead of br x<n> where possible

[Jonathan Wright]

Hi,

This patch changes all AArch64 assembly code to use:
  ret     x<n>
instead of:
  br      x<n>

"ret x<n>" is already used in a lot of places so this patch makes it
consistent across the code base. This does not change behavior or
performance.

In addition, this change reduces the number of landing pads needed in
a subsequent patch to support the Armv8.5-A Branch Target
Identification (BTI) security feature.

Regression tested and no issues. Could someone take a look and
merge?

Thanks,
Jonathan
