Detailed Description

Cast of LLVM instructions FPTrunc/Trunc.

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

Constructor & Destructor Documentation

◆ TruncCastExpr()

retdec::llvmir2hll::TruncCastExpr::TruncCastExpr ( ShPtr< Expression op,
ShPtr< Type dstType 
)
private

Constructs a cast operator of LLVM instructions FPTrunc/Trunc.

See create() for more information.

Member Function Documentation

◆ accept()

void retdec::llvmir2hll::TruncCastExpr::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::TruncCastExpr::clone ( )
overridevirtual

Clones the cast operator.

Implements retdec::llvmir2hll::Value.

◆ create()

ShPtr< TruncCastExpr > retdec::llvmir2hll::TruncCastExpr::create ( ShPtr< Expression op,
ShPtr< Type dstType 
)
static

Creates a new cast operator of LLVM instructions FPTrunc/Trunc.

Parameters
[in]opOperand.
[in]dstTypeDestination type.
Preconditions
  • operand is non-null

◆ isEqualTo()

bool retdec::llvmir2hll::TruncCastExpr::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.
