From fd7c3c3767c38dbbf2f5c993c6fd42a71846e7e0 Mon Sep 17 00:00:00 2001 From: Mark-PK Tsai Date: Thu, 19 Oct 2023 09:35:22 +0100 Subject: ARM: 9327/1: vfp: Add missing VFP instructions to neon_support_hook Add the missing "Unconditional Advanced SIMD and floating-point instructions" in [1] to the VFP undef hook. This commit addresses the issue reported in [2], where executing the vudot instruction on a platform with FEAT_DotProd support resulted in an undefined instruction error.
