Detailed Description

A representation of an float point type.

Use create() to create instances. Instances of this class have reference object semantics. This class is not meant to be subclassed.

Member Typedef Documentation

◆ SizeToFloatTypeMap

using retdec::llvmir2hll::FloatType::SizeToFloatTypeMap = std::map<unsigned, ShPtr<FloatType> >
private

Mapping of float point type sizes into FloatType instances.

Constructor & Destructor Documentation

◆ FloatType()

retdec::llvmir2hll::FloatType::FloatType ( unsigned  size)
private

Constructs a new float type.

See create() for more information.

Member Function Documentation

◆ accept()

void retdec::llvmir2hll::FloatType::accept ( Visitor v)
overridevirtual

Visitor pattern implementation.

Subclasses should implement this method as:

v->visit(ucast<T>(shared_from_this()));

where T is the name of the subclass, and shared_from_this() and ucast<> are from Decompiler/Support/SmartPtr.h.

Implements retdec::llvmir2hll::Visitable.

◆ clone()

ShPtr< Value > retdec::llvmir2hll::FloatType::clone ( )
overridevirtual

Returns a clone of the value.

A clone is (in most cases) an exact copy of the value. This member function provides the copy mechanism for reference objects.

The following parts of values are not cloned:

  • predecessors and successors of statements

The following subclasses of Value are not cloned, i.e. they are returned without any copying:

Statements in compound statements (i.e. statements where isCompound() returns true) are cloned without their successors; therefore, e.g., just the first statement of every if's clause is cloned.

Implements retdec::llvmir2hll::Value.

◆ create()

ShPtr< FloatType > retdec::llvmir2hll::FloatType::create ( unsigned  size)
static

Creates a new float type.

Parameters
[in]sizeNumber of bits.

◆ existsFloatType()

bool retdec::llvmir2hll::FloatType::existsFloatType ( ) const

Returns true if exists float type.

Returns
Returns true if exists float type, else false.

◆ existsFloatTypeWith()

bool retdec::llvmir2hll::FloatType::existsFloatTypeWith ( unsigned  size) const

Returns true if exists type with size defined in args.

Parameters
[in]sizeNumber of bits.
Returns
Returns true if exists type, else false.

◆ getSize()

unsigned retdec::llvmir2hll::FloatType::getSize ( ) const

Returns the number of bits.

◆ isEqualTo()

bool retdec::llvmir2hll::FloatType::isEqualTo ( ShPtr< Value otherValue) const
overridevirtual

Returns true if this value is equal to otherValue, false otherwise.

This member function brings the support of value object semantics into reference objects, namely equality based not only on identity.

This function doesn't consider observers, metadata, etc.

Implements retdec::llvmir2hll::Value.

Member Data Documentation

◆ createdTypes

std::map< unsigned, ShPtr< FloatType > > retdec::llvmir2hll::FloatType::createdTypes
staticprivate

Set of already created float point types of the given size.

◆ size

unsigned retdec::llvmir2hll::FloatType::size
private

Number of bits (size of the float point type).
