The GNU assembler for ARM version 2.22 or older fails to infer the element size from the vmov instructions, and aborts the build in the following way; .../aes-neonbs-core.S: Assembler messages: .../aes-neonbs-core.S:817: Error: bad type for scalar -- `vmov q1h[1],r10' .../aes-neonbs-core.S:817: Error: bad type for scalar -- `vmov q1h[0],r9' .../aes-neonbs-core.S:817: Error: bad type for scalar -- `vmov q1l[1],r8' .../aes-neonbs-core.S:817: Error: bad type for scalar -- `vmov q1l[0],r7' .../aes-neonbs-core.S:818: Error: bad type for scalar -- `vmov q2h[1],r10' .../aes-neonbs-core.S:818: Error: bad type for scalar -- `vmov q2h[0],r9' .../aes-neonbs-core.S:818: Error: bad type for scalar -- `vmov q2l[1],r8' .../aes-neonbs-core.S:818: Error: bad type for scalar -- `vmov q2l[0],r7' Fix this by setting the element size explicitly, by replacing vmov with vmov.32.
