Member Function Documentation

◆ eval()

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

Evaluates and.

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

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

◆ getExpressionStr()

StringRef llvm::ExpressionAST::getExpressionStr ( ) const

◆ getImplicitFormat()

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