From a04b68e1d4c4f0cd5cd7542697b1b230b84532f5 Mon Sep 17 00:00:00 2001 From: Richard Henderson <richard.henderson@linaro.org> Date: Thu, 14 May 2020 14:28:26 -0700 Subject: target/arm: Convert aes and sm4 to gvec helpers With this conversion, we will be able to use the same helpers with sve. In particular, pass 3 vector parameters for the 3-operand operations; for advsimd the destination register is also an input. This also fixes a bug in which we failed to clear the high bits of the SVE register after an AdvSIMD operation.
