From 991b6a22b6592b56ae890f30c478f835480e7cf5 Mon Sep 17 00:00:00 2001 From: Michael Liao Date: Wed, 24 Oct 2012 04:09:32 +0000 Subject: Add custom conversion from v2u32 to v2f32 in 32-bit mode - As there's no 64-bit GPRs in 32-bit mode, a custom conversion from v2u32 to v2f32 is added to improve the efficiency of the code generated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166545 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/X86/cvtv2f32.ll | 11 +++++++++++ 1 file changed, 11 insertions(+) create mode 100644 test/CodeGen/X86/cvtv2f32.ll (limited to 'test') diff --git a/test/CodeGen/X86/cvtv2f32.ll b/test/CodeGen/X86/cvtv2f32.ll new file mode 100644 index 0000000000..5a27a48910 --- /dev/null +++ b/test/CodeGen/X86/cvtv2f32.ll @@ -0,0 +1,11 @@ +; RUN: llc < %s -mtriple=i686-linux-pc -mcpu=corei7 | FileCheck %s + +define <2 x float> @bar(<2 x i32> %in) { + %r = uitofp <2 x i32> %in to <2 x float> + ret <2 x float> %r +; CHECK: bar +; CHECK: or +; CHECK: subpd +; CHECK: cvtpd2ps +; CHECK: ret +} -- cgit v1.2.3
