Subject: [FFmpeg-devel] [PATCH 18/21] aarch64: hevc: Produce plain neon versions of qpel_hv
Date: Mon, 25 Mar 2024 17:02:40 +0200
Message-ID: <20240325150243.59058-19-martin@martin.st> (raw)
In-Reply-To: <20240325150243.59058-1-martin@martin.st>
As the plain neon qpel_h functions process two rows at a time,
we need to allocate storage for h+8 rows instead of h+7.
By allocating storage for h+8 rows, incrementing the stack
pointer won't end up at the right spot in the end. Store the
intended final stack pointer value in a register x14 which we
store on the stack.
