From 0534863c477240e47f1d85616b59c31fad453ea2 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Samuel=20Iglesias=20Gons=C3=A1lvez?= Date: Thu, 7 Jul 2016 13:55:32 +0200 Subject: [PATCH] i965/eu: set DF imm value to the source of DIM MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit According to HSW's PRM, vol02b, the DIM instruction has the following restriction: "Restriction : src0 must be immediate. src0 must specify the :f (F, Float) type encoding but is an immediate 64-bit DF (Double Float) value. dst must have type DF." This commit allows to upload the immediate 64-bit DF value to the source of a DIM instruction even when it is of float type encoding.
