From 1b430aec4157b62b9add981b1849c8c23ca78f5a Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Thu, 11 Apr 2019 11:56:49 +0200 Subject: [PATCH] s390x/tcg: Implement VECTOR MULTIPLY AND ADD * Quite some variants to handle. At least handle some 32-bit element variants via gvec expansion (we could also handle 16/32-bit variants for ODD and EVEN easily via gvec expansion, but let's keep it simple for now).
