From 033e1fcd97babd6302fd7e983102966a2cafb95c Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Sun, 16 Jun 2019 13:37:44 +0100 Subject: [PATCH] target/ppc: introduce GEN_VSX_HELPER_X2_AB macro to fpu_helper.c Rather than perform the VSR register decoding within the helper itself, introduce a new GEN_VSX_HELPER_X2_AB macro which performs the decode based upon xA and xB at translation time.
