From 846c19dd7003d5de701a12ecdf31af8615bdfc1a Mon Sep 17 00:00:00 2001 From: Rafael Espindola Date: Fri, 19 Oct 2007 10:41:11 +0000 Subject: Add support for byval function whose argument is not 32 bit aligned. To do this it is necessary to add a "always inline" argument to the memcpy node. For completeness I have also added this node to memmove and memset. I have also added getMem* functions, because the extra argument makes it cumbersome to use getNode and because I get confused by it :-) llvm-svn: 43172 --- llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cpp | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) (limited to 'llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cpp') diff --git a/llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cpp b/llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cpp index e6ce2eb9951..09e8b579a0f 100644 --- a/llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cpp +++ b/llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cpp @@ -2269,6 +2269,30 @@ SDOperand SelectionDAG::getNode(unsigned Opcode, MVT::ValueType VT, return getNode(Opcode, VT, Ops, 5); } +SDOperand SelectionDAG::getMemcpy(SDOperand Chain, SDOperand Dest, + SDOperand Src, SDOperand Size, + SDOperand Align, + SDOperand AlwaysInline) { + SDOperand Ops[] = { Chain, Dest, Src, Size, Align, AlwaysInline }; + return getNode(ISD::MEMCPY, MVT::Other, Ops, 6); +} + +SDOperand SelectionDAG::getMemmove(SDOperand Chain, SDOperand Dest, + SDOperand Src, SDOperand Size, + SDOperand Align, + SDOperand AlwaysInline) { + SDOperand Ops[] = { Chain, Dest, Src, Size, Align, AlwaysInline }; + return getNode(ISD::MEMMOVE, MVT::Other, Ops, 6); +} + +SDOperand SelectionDAG::getMemset(SDOperand Chain, SDOperand Dest, + SDOperand Src, SDOperand Size, + SDOperand Align, + SDOperand AlwaysInline) { + SDOperand Ops[] = { Chain, Dest, Src, Size, Align, AlwaysInline }; + return getNode(ISD::MEMSET, MVT::Other, Ops, 6); +} + SDOperand SelectionDAG::getLoad(MVT::ValueType VT, SDOperand Chain, SDOperand Ptr, const Value *SV, int SVOffset, -- cgit v1.2.3
