Detailed Description

template<class Size_T>
class llvm::SmallVectorBase< Size_T >

This is all the stuff common to all SmallVectors.

The template parameter specifies the type which should be used to hold the Size and Capacity of the SmallVector, so it can be adjusted. Using 32 bit size is desirable to shrink the size of the SmallVector. Using 64 bit size is desirable for cases like SmallVector<char>, where a 32 bit size would limit the vector to ~4GB. SmallVectors are used for buffering bitcode output - which can exceed 4GB.

void SmallVectorBase::grow_pod ( void * FirstEl, size_t MinSize, size_t TSize )

This is an implementation of the grow() method which only works on POD-like data types and is out of line to reduce code duplication.

This function will report a fatal error if it cannot increase capacity.

mallocForGrow()

template<class Size_T>

void * SmallVectorBase::mallocForGrow ( void * FirstEl, size_t MinSize, size_t TSize, size_t & NewCapacity )

protected

This is a helper for grow() that's out of line to reduce code duplication.

This function will report a fatal error if it can't grow at least to MinSize.

set_allocation_range()

template<class Size_T>

void llvm::SmallVectorBase< Size_T >::set_allocation_range ( void * Begin, size_t N )

Set the array data pointer to Begin and capacity to N.

This does not construct or destroy any elements in the vector.
