From 01dfc0ed7f2c5f8dbab65f31228a2888c7b85a07 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Sun, 2 Jan 2022 17:42:07 -0800 Subject: tcg/arm: Drop support for armv4 and armv5 hosts Support for unaligned accesses is difficult for pre-v6 hosts. While debian still builds for armv4, we cannot use a compile time test, so test the architecture at runtime and error out.
