From 5e764233f398b6929b67701672a5e78fec20ce2e Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Sat, 26 Apr 2008 23:02:14 +0000 Subject: A few inline asm cleanups: - Make targetlowering.h fit in 80 cols. - Make LowerAsmOperandForConstraint const. - Make lowerXConstraint -> LowerXConstraint - Make LowerXConstraint return a const char* instead of taking a string byref. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50312 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/SelectionDAG/TargetLowering.cpp | 14 ++++++-------- 1 file changed, 6 insertions(+), 8 deletions(-) (limited to 'lib/CodeGen/SelectionDAG/TargetLowering.cpp') diff --git a/lib/CodeGen/SelectionDAG/TargetLowering.cpp b/lib/CodeGen/SelectionDAG/TargetLowering.cpp index f69f046..6c15ff9 100644 --- a/lib/CodeGen/SelectionDAG/TargetLowering.cpp +++ b/lib/CodeGen/SelectionDAG/TargetLowering.cpp @@ -1534,14 +1534,12 @@ TargetLowering::getConstraintType(const std::string &Constraint) const { /// LowerXConstraint - try to replace an X constraint, which matches anything, /// with another that has more specific requirements based on the type of the /// corresponding operand. -void TargetLowering::lowerXConstraint(MVT::ValueType ConstraintVT, - std::string& s) const { +const char *TargetLowering::LowerXConstraint(MVT::ValueType ConstraintVT) const{ if (MVT::isInteger(ConstraintVT)) - s = "r"; - else if (MVT::isFloatingPoint(ConstraintVT)) - s = "f"; // works for many targets - else - s = ""; + return "r"; + if (MVT::isFloatingPoint(ConstraintVT)) + return "f"; // works for many targets + return 0; } /// LowerAsmOperandForConstraint - Lower the specified operand into the Ops @@ -1549,7 +1547,7 @@ void TargetLowering::lowerXConstraint(MVT::ValueType ConstraintVT, void TargetLowering::LowerAsmOperandForConstraint(SDOperand Op, char ConstraintLetter, std::vector &Ops, - SelectionDAG &DAG) { + SelectionDAG &DAG) const { switch (ConstraintLetter) { default: break; case 'X': // Allows any operand; labels (basic block) use this. -- cgit v1.1
