zbb created this revision. zbb added reviewers: imp, ian, andrew. zbb added a subscriber: freebsd-arm. REVISION SUMMARY This patch allows taking advantage of disabling alignment fault handling on ARM platforms. Although some CPU instructions are capable to operate on unaligned addresses they may still as a side effect report it. This option allows to avoid related performance overhead, but suppresses this notification.
