From 861285c146b267187af20a63c8541c4e5a4d871e Mon Sep 17 00:00:00 2001 From: Andre Kempe Date: Mon, 25 Apr 2022 08:33:40 +0000 Subject: [PATCH] arm64: Fix wrong BTI landing pad MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch fixes a wrong type of BTI landing pad when branching to functions instantiated via the fft*_neon macro. Although the previously employed paciasp instruction serves as a landing pad, for the ways that this function is invoked it is the wrong type, resulting in an unexpected termination of the running process.
