<h5>Overview:</h5>
|
||||
<p>The packed structure type is used to represent a collection of data members
|
||||
together in memory. There is no padding between fields. Further, the alignment
|
||||
of a packed structure is 1 byte. The elements of a packed structure may
|
||||
be any type that has a size.</p>
|
||||
<p>Structures are accessed using '<tt><a href="#i_load">load</a></tt>
|
||||
and '<tt><a href="#i_store">store</a></tt>' by getting a pointer to a
|
||||
field with the '<tt><a href="#i_getelementptr">getelementptr</a></tt>'
|
||||
instruction.</p>

||||
