Member Function Documentation

eval()

virtual Expected< APInt > llvm::ExpressionAST::eval ( ) const

pure virtual

Evaluates and.

Returns

the value of the expression represented by this AST or an error if evaluation fails.

Implemented in llvm::ExpressionLiteral, llvm::NumericVariableUse, and llvm::BinaryOperation.

Referenced by llvm::FileCheckPatternContext::defineCmdlineVariables().

getExpressionStr()

StringRef llvm::ExpressionAST::getExpressionStr ( ) const

inline

Definition at line 135 of file FileCheckImpl.h.

Referenced by llvm::NumericVariableUse::eval(), and llvm::BinaryOperation::getImplicitFormat().

getImplicitFormat()

virtual Expected< ExpressionFormat > llvm::ExpressionAST::getImplicitFormat ( const SourceMgr &  SM ) const

inlinevirtual

Returns

either the implicit format of this AST, a diagnostic against SM if implicit formats of the AST's components conflict, or NoFormat if the AST has no implicit format (e.g. AST is made up of a single literal).

Reimplemented in llvm::NumericVariableUse, and llvm::BinaryOperation.
