.. _DONT_CHAIN_GET_ELEM_PTR:

DONT_CHAIN_GET_ELEM_PTR
-------------

By default, LegUp assumes that get element pointer instructions take zero time 
in hardware and will therefore chain consecutive get element pointer 
instructions into a single cycle. This default behaviour can be disabled by 
setting the DONT_CHAIN_GET_ELEM_PTR constraint to zero. This will split 
dependent get element pointer instructions into seperate clock cycles.
