Class Arith

java.lang.Object
  avrora.core.isdl.ast.Expr
      avrora.core.isdl.ast.Arith

Direct Known Subclasses:

Arith.BinOp, Arith.UnOp

public abstract class Arith

extends Expr

The Arith class is a container for classes that represent integer arithmetic in the IR. For example, the class Arith.AddExpr represents an expression that is the addition of two integers. The result of all operations on integers are integers, therefore, every expression that is a subclass of Arith has a result type of integer.

Nested Class Summary

static class	Arith.AddExpr The AddExpr inner class represents the addition of two integer values that produces a new integer value.
static class	Arith.AndExpr The AndExpr class represents the bitwise and of two integer values that produces a single integer result.
static class	Arith.BinOp The BinOp inner class represents an operation on two integers with an infix binary operation.
static class	Arith.CompExpr The CompExpr class represents the bitwise complement of an integer value that produces a single integer result.
static class	Arith.DivExpr The DivExpr inner class represents a division operation on two integer values which produces a single integer result.
static class	Arith.MulExpr The MulExpr inner class represents the multiplication of two integer values which produces a single integer result.
static class	Arith.NegExpr The NegExpr class represents the negation (sign reversal) of an integer value that produces a single integer result.
static class	Arith.OrExpr The OrExpr class represents the bitwise inclusive or of two integer values that produces a single integer result.
static class	Arith.ShiftLeftExpr The ShiftLeftExpr class represents the shift left of an integer value that produces a single integer result.
static class	Arith.ShiftRightExpr The ShiftRightExpr class represents the shift left of an integer value that produces a single integer result.
static class	Arith.SubExpr The SubExpr inner class represents the subtraction of one integer value from another that results in a new integer value.
static class	Arith.UnOp The UnOp inner class represents an operation on a single integer value.
static class	Arith.XorExpr The XorExpr class represents the bitwise exclusive or of two integer values that produces a single integer result.
