Subject: [FFmpeg-devel] [PATCH] Replace br return with ret
Date: Thu, 27 Jul 2023 11:26:26 +0100
Message-ID: <667c0538-92d0-84d6-7459-ccb4194f2ea7@arm.com> (raw)
This patch changes the return instruction in the
tr_32x4 macro from br to ret.
On devices that support BTI a landing pad is
required when branching with br, or the instruction
can be replaced with a ret.
The change fixes fate-hevc-hdr-vivid-metadata when
on hardware with BTI support.
