From 4106f3714e8fc2d3561a3e64244d560b4cc41837 Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Wed, 18 Jul 2007 20:23:34 +0000 Subject: Implement initial memory alignment awareness for SSE instructions. Vector loads and stores that have a specified alignment of less than 16 bytes now use instructions that support misaligned memory references. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40015 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/X86/sse-align-2.ll | 14 ++++++++++++++ 1 file changed, 14 insertions(+) create mode 100644 test/CodeGen/X86/sse-align-2.ll (limited to 'test/CodeGen/X86/sse-align-2.ll') diff --git a/test/CodeGen/X86/sse-align-2.ll b/test/CodeGen/X86/sse-align-2.ll new file mode 100644 index 0000000..b5c0674 --- /dev/null +++ b/test/CodeGen/X86/sse-align-2.ll @@ -0,0 +1,14 @@ +; RUN: llvm-as < %s | llc -march=x86-64 | grep movup | wc -l | grep 2 + +define <4 x float> @foo(<4 x float>* %p, <4 x float> %x) +{ + %t = load <4 x float>* %p, align 4 + %z = mul <4 x float> %t, %x + ret <4 x float> %z +} +define <2 x double> @bar(<2 x double>* %p, <2 x double> %x) +{ + %t = load <2 x double>* %p, align 8 + %z = mul <2 x double> %t, %x + ret <2 x double> %z +} -- cgit v1.1
