--- Comment #6 from richard.sandiford at arm dot com --- Here's a proof of concept patch that fixes the testcase for -mstrict-align. The VECTOR_MODE_P part would need to be behind a new target hook, to avoid accidentally breaking someone's ABI. For default-align, we should probably make double[4] use V4DFmode via aarch64_array_mode.
