When converting a DF to 32-bit conversions, we set dst stride to 2, to fulfill alignment restrictions because the upper Dword of every Qword will be written with undefined value. But in IVB/BYT, this is not necessary, as each DF conversion already writes 2, the first one the real value, and the second one a 0. That is, IVB/BYT already set stride = 2 implicitly, so we must set it to 1 explicitly to avoid ending up with stride = 4. v2: - Fix typo (Matt) v3: - Fix stride in the destination's brw_reg, don't modity IR (Curro) v4: - Remove 'is_dst' argument of brw_reg_from_fs_reg() (Curro) - Fix comment (Curro). - Relax hstride assert (Curro) Signed-off-by: Juan A.
