Methods

¶ConstraintInfo(llvm::StringRef ConstraintStr,
               llvm::StringRef Name)

Declared at: clang/include/clang/Basic/TargetInfo.h:1024

Parameters

llvm::StringRef ConstraintStr

llvm::StringRef Name

¶bool allowsMemory() const

Declared at: clang/include/clang/Basic/TargetInfo.h:1036

¶bool allowsRegister() const

Declared at: clang/include/clang/Basic/TargetInfo.h:1035

¶bool earlyClobber()

Declared at: clang/include/clang/Basic/TargetInfo.h:1034

¶const std::string& getConstraintStr() const

Declared at: clang/include/clang/Basic/TargetInfo.h:1031

¶const std::string& getName() const

Declared at: clang/include/clang/Basic/TargetInfo.h:1032

¶unsigned int getTiedOperand() const

Declared at: clang/include/clang/Basic/TargetInfo.h:1048

¶bool hasMatchingInput() const

Description

Return true if this output operand has a matching (tied) input operand.

Declared at: clang/include/clang/Basic/TargetInfo.h:1040

¶bool hasTiedOperand() const

Description

Return true if this input operand is a matching constraint that ties it to an output operand. If this returns true then getTiedOperand will indicate which output operand this is tied to.
