From 1ca69fa64da40e7286f5f9d8e577017cd64b782c Mon Sep 17 00:00:00 2001 From: Bill Schmidt Date: Fri, 31 Oct 2014 19:19:07 +0000 Subject: [PowerPC] Initial VSX intrinsic support, with min/max for vector double Now that we have initial support for VSX, we can begin adding intrinsics for programmer access to VSX instructions. This patch adds basic support for VSX intrinsics in general, and tests it by implementing intrinsics for minimum and maximum for the vector double data type. The LLVM portion of this is quite straightforward. There is a companion patch for Clang. llvm-svn: 220988 --- llvm/lib/Target/PowerPC/PPCInstrVSX.td | 24 ++++++++++++++++++------ 1 file changed, 18 insertions(+), 6 deletions(-) (limited to 'llvm/lib/Target') diff --git a/llvm/lib/Target/PowerPC/PPCInstrVSX.td b/llvm/lib/Target/PowerPC/PPCInstrVSX.td index a7c95fb5f84..3dfdf0806e3 100644 --- a/llvm/lib/Target/PowerPC/PPCInstrVSX.td +++ b/llvm/lib/Target/PowerPC/PPCInstrVSX.td @@ -643,24 +643,36 @@ let Uses = [RM] in { let isCommutable = 1 in { def XSMAXDP : XX3Form<60, 160, (outs vsfrc:$XT), (ins vsfrc:$XA, vsfrc:$XB), - "xsmaxdp $XT, $XA, $XB", IIC_VecFP, []>; + "xsmaxdp $XT, $XA, $XB", IIC_VecFP, + [(set vsfrc:$XT, + (int_ppc_vsx_xsmaxdp vsfrc:$XA, vsfrc:$XB))]>; def XSMINDP : XX3Form<60, 168, (outs vsfrc:$XT), (ins vsfrc:$XA, vsfrc:$XB), - "xsmindp $XT, $XA, $XB", IIC_VecFP, []>; + "xsmindp $XT, $XA, $XB", IIC_VecFP, + [(set vsfrc:$XT, + (int_ppc_vsx_xsmindp vsfrc:$XA, vsfrc:$XB))]>; def XVMAXDP : XX3Form<60, 224, (outs vsrc:$XT), (ins vsrc:$XA, vsrc:$XB), - "xvmaxdp $XT, $XA, $XB", IIC_VecFP, []>; + "xvmaxdp $XT, $XA, $XB", IIC_VecFP, + [(set vsrc:$XT, + (int_ppc_vsx_xvmaxdp vsrc:$XA, vsrc:$XB))]>; def XVMINDP : XX3Form<60, 232, (outs vsrc:$XT), (ins vsrc:$XA, vsrc:$XB), - "xvmindp $XT, $XA, $XB", IIC_VecFP, []>; + "xvmindp $XT, $XA, $XB", IIC_VecFP, + [(set vsrc:$XT, + (int_ppc_vsx_xvmindp vsrc:$XA, vsrc:$XB))]>; def XVMAXSP : XX3Form<60, 192, (outs vsrc:$XT), (ins vsrc:$XA, vsrc:$XB), - "xvmaxsp $XT, $XA, $XB", IIC_VecFP, []>; + "xvmaxsp $XT, $XA, $XB", IIC_VecFP, + [(set vsrc:$XT, + (int_ppc_vsx_xvmaxsp vsrc:$XA, vsrc:$XB))]>; def XVMINSP : XX3Form<60, 200, (outs vsrc:$XT), (ins vsrc:$XA, vsrc:$XB), - "xvminsp $XT, $XA, $XB", IIC_VecFP, []>; + "xvminsp $XT, $XA, $XB", IIC_VecFP, + [(set vsrc:$XT, + (int_ppc_vsx_xvminsp vsrc:$XA, vsrc:$XB))]>; } // isCommutable } // Uses = [RM] -- cgit v1.2.3
