Constructor & Destructor Documentation

SgAsmFloatValueExpression::SgAsmFloatValueExpression ( double  nativeValue,
SgAsmType  
)

Construct specified floating-point value.

Creates a new floating-point constant AST node having the specified native value and type. See also, the constructor that takes a bit vector as its first argument, which is useful in cases where the native representation of a floating point value does not match the target machine's representation.

On the other hand, the default constructor creates a new floating-point value of unspecified type initialized to positive zero. We recommend using a constructor that takes a SgAsmType argument instead.

SgAsmFloatValueExpression::SgAsmFloatValueExpression ( const Sawyer::Container::BitVector ,
SgAsmType  
)

Construct specified floating-point value.

Creates a new floating-point constant AST node having the specified value and type. See also, the constructor that takes a double argument for those cases when the native representation matches the target machine's representation.

virtual SgAsmFloatValueExpression::~SgAsmFloatValueExpression ( )
virtual

Destructor.

SgAsmFloatValueExpression::SgAsmFloatValueExpression ( )

Default constructor.

Member Function Documentation

void SgAsmFloatValueExpression::set_nativeValue ( double  )

Set AST node value to specified native value.

double SgAsmFloatValueExpression::get_nativeValue ( ) const

Get value in native format.

void SgAsmFloatValueExpression::updateBitVector ( )

Update bit vector from native representation.

Resets the bit vector using the cached native representation. The bit vector is considered to be the canonical value of this AST node.

void SgAsmFloatValueExpression::updateNativeValue ( ) const

Update cached native value from bit vector.

Resets the cached native value from the bit vector. The bit vector is considered to be the canonical value of this AST node, and the native format value is a cached representation that can be used in arithmetic.

void SgAsmFloatValueExpression::initializeProperties ( )
protected

Initialize all properties that have explicit initial values.

This function is mostly for use in user-defined constructors where the user desires to initialize all the properties but does not know the names of the data members that store the property values. This function initializes the properties that have explicit initializations within this class, but does not recursively initialize base classes.
