From 13954e788dc7e3a47cc00419c120a63756be4eb1 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Thu, 19 Jan 2017 12:23:32 +0000 Subject: crypto: arm/aes-neonbs - fix issue with v2.22 and older assembler 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.
