From a5134a0ea3ee9e12ae3ca7907b7998e0d7f4d441 Mon Sep 17 00:00:00 2001 From: Bruno Cardoso Lopes Date: Thu, 11 Aug 2011 02:49:41 +0000 Subject: Use the splat index to generate the desired shuffle. Otherwise we could only get undefs and the vector shuffle becomes an undef, generating wrong code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137295 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/X86/avx-splat.ll | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'test/CodeGen/X86/avx-splat.ll') diff --git a/test/CodeGen/X86/avx-splat.ll b/test/CodeGen/X86/avx-splat.ll index 36d469417f..243ab9ba31 100644 --- a/test/CodeGen/X86/avx-splat.ll +++ b/test/CodeGen/X86/avx-splat.ll @@ -77,3 +77,13 @@ __load_and_broadcast_32.exit1249: ; preds = %load.i1247, %for_ex ret void } +; CHECK: vpshufd $0 +; CHECK-NEXT: vinsertf128 $1 +define <8 x float> @funcF(i32* %ptr) nounwind { + %val = load i32* %ptr, align 4 + %ret6 = insertelement <8 x i32> undef, i32 %val, i32 6 + %ret7 = insertelement <8 x i32> %ret6, i32 %val, i32 7 + %tmp = bitcast <8 x i32> %ret7 to <8 x float> + ret <8 x float> %tmp +} + -- cgit v1.2.3
