Subject: [kvm-unit-tests PATCH v2 1/4] riscv: Drop mstrict-align
Date: Wed,  4 Sep 2024 12:50:22 +0200	[thread overview]
Message-ID: <20240904105020.1179006-7-andrew.jones@linux.dev> (raw)
In-Reply-To: <20240904105020.1179006-6-andrew.jones@linux.dev>

The spec says unaligned accesses are supported, so this isn't required
and clang doesn't support it. A platform might have slow unaligned
accesses, but kvm-unit-tests isn't about speed anyway.
