Elena Demikhovsky 52981c4b60 I optimized the following patterns: ... sext <4 x i1> to <4 x i64> sext <4 x i8> to <4 x i64> sext <4 x i16> to <4 x i64> I'm running Combine on SIGN_EXTEND_IN_REG and revert SEXT patterns: (sext_in_reg (v4i64 anyext (v4i32 x )), ExtraVT) -> (v4i64 sext (v4i32 sext_in_reg (v4i32 x , ExtraVT))) The sext_in_reg (v4i32 x) may be lowered to shl+sar operations. The "sar" does not exist on 64-bit operation, so lowering sext_in_reg (v4i64 x) has no vector solution. I also added a cost of this operations to the AVX costs table. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175619 91177308-0d34-0410-b5e6-96231b3b80d8		2013-02-20 12:42:54 +00:00
