From af95a70a06d361fa068f1579e0b206f3a5e5de0f Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Thu, 21 Apr 2022 08:17:05 -0700 Subject: [PATCH] target/nios2: Handle EXCP_UNALIGN and EXCP_UNALIGND While some of the plumbing for misaligned data is present, in the form of nios2_cpu_do_unaligned_access, the hook will not be called because TARGET_ALIGNED_ONLY is not set in configs/targets/nios2-softmmu.mak.
