From c7849c22f4804075c0c972e20f9cd701bdb6ab6f Mon Sep 17 00:00:00 2001 From: Mon P Wang Date: Sun, 16 Nov 2008 05:06:27 +0000 Subject: Improved shuffle normalization to avoid using extract/build when we can extract using different indexes for two vectors. Added a few tests for vector shuffles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59399 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/X86/vec_shuffle-27.ll | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) create mode 100644 test/CodeGen/X86/vec_shuffle-27.ll (limited to 'test/CodeGen/X86/vec_shuffle-27.ll') diff --git a/test/CodeGen/X86/vec_shuffle-27.ll b/test/CodeGen/X86/vec_shuffle-27.ll new file mode 100644 index 0000000..6baf47a --- /dev/null +++ b/test/CodeGen/X86/vec_shuffle-27.ll @@ -0,0 +1,17 @@ +; RUN: llvm-as < %s | llc -march=x86 -mattr=sse41 -o %t -f +; RUN: grep addps %t | count 2 +; RUN: grep mulps %t | count 2 +; RUN: grep subps %t | count 2 + +; ModuleID = 'vec_shuffle-27.bc' +target datalayout = "e-p:32:32:32-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:32:64-f32:32:32-f64:32:64-v64:64:64-v128:128:128-a0:0:64-f80:32:32" +target triple = "i686-apple-cl.1.0" + +define <8 x float> @my2filter4_1d(<4 x float> %a, <8 x float> %T0, <8 x float> %T1) nounwind readnone { +entry: + %tmp7 = shufflevector <4 x float> %a, <4 x float> undef, <8 x i32> < i32 0, i32 1, i32 2, i32 3, i32 0, i32 1, i32 2, i32 3 > ; <<8 x float>> [#uses=1] + %sub = sub <8 x float> %T1, %T0 ; <<8 x float>> [#uses=1] + %mul = mul <8 x float> %sub, %tmp7 ; <<8 x float>> [#uses=1] + %add = add <8 x float> %mul, %T0 ; <<8 x float>> [#uses=1] + ret <8 x float> %add +} -- cgit v1.1
