void operator delete	(	void *	Ptr,
		llvm::MCContext &	C,
		size_t
	)		throw () [inline]

Placement delete companion to the new above.

This operator is just a companion to the new above. There is no way of invoking it directly; see the new operator for more details. This operator is called implicitly by the compiler if a placement new expression using the MCContext throws in the object constructor.

void operator delete[]	(	void *	Ptr,
		llvm::MCContext &	C
	)		throw () [inline]

Placement delete[] companion to the new[] above.

This operator is just a companion to the new[] above. There is no way of invoking it directly; see the new[] operator for more details. This operator is called implicitly by the compiler if a placement new[] expression using the MCContext throws in the object constructor.

void* operator new	(	size_t	Bytes,
		llvm::MCContext &	C,
		size_t	Alignment = 16
	)		throw () [inline]

Placement new for using the MCContext's allocator.

This placement form of operator new uses the MCContext's allocator for obtaining memory. It is a non-throwing new, which means that it returns null on error. (If that is what the allocator does. The current does, so if this ever changes, this operator will have to be changed, too.) Usage looks like this (assuming there's an MCContext 'Context' in scope):

 // Default alignment (16)
 IntegerLiteral *Ex = new (Context) IntegerLiteral(arguments);
 // Specific alignment
 IntegerLiteral *Ex2 = new (Context, 8) IntegerLiteral(arguments);

Please note that you cannot use delete on the pointer; it must be deallocated using an explicit destructor call followed by Context.Deallocate(Ptr).

Parameters:

Bytes	The number of bytes to allocate. Calculated by the compiler.
C	The MCContext that provides the allocator.
Alignment	The alignment of the allocated memory (if the underlying allocator supports it).

Returns:

The allocated memory. Could be NULL.

void* operator new[]	(	size_t	Bytes,
		llvm::MCContext &	C,
		size_t	Alignment = 16
	)		throw () [inline]

This placement form of operator new[] uses the MCContext's allocator for obtaining memory. It is a non-throwing new[], which means that it returns null on error. Usage looks like this (assuming there's an MCContext 'Context' in scope):

 // Default alignment (16)
 char *data = new (Context) char[10];
 // Specific alignment
 char *data = new (Context, 8) char[10];

Please note that you cannot use delete on the pointer; it must be deallocated using an explicit destructor call followed by Context.Deallocate(Ptr).

Parameters:

Bytes	The number of bytes to allocate. Calculated by the compiler.
C	The MCContext that provides the allocator.
Alignment	The alignment of the allocated memory (if the underlying allocator supports it).

Returns:

The allocated memory. Could be NULL.
