template<typename T >

void va_stack::alloc ( vec< T, va_stack, vl_ptr > &  v, unsigned  nelems, vec< T, va_stack, vl_embed > *  space  )

static

Allocate a vector V which uses alloca for the initial allocation.
   SPACE is space allocated using alloca.  NELEMS is the number of
   entries allocated.

template<typename T >

void va_stack::release ( vec< T, va_stack, vl_embed > *&  v )

static

Free a vector allocated on the stack.  Don't actually free it if we
   find it in the hash table.

template<typename T >

static void va_stack::reserve ( vec< T, va_stack, vl_embed > *&  , unsigned  , bool  CXX_MEM_STAT_INFO  )

static

template<typename T >

void va_stack::reserve	(	vec< T, va_stack, vl_embed > *&	v,
		unsigned	nelems,
		bool exact	MEM_STAT_DECL
	)

Reserve NELEMS slots for a vector initially allocated on the stack.
   When this happens, we switch back to heap allocation.  We remove
   the vector from stack_vecs, if it is there, since we no longer need
   to avoid freeing it.  If EXACT is true, grow exactly, otherwise
   grow exponentially.
