@ -1947,15 +1947,9 @@ following is the syntax for constant expressions:</p>
<i>really</i> dangerous!</dd>
<dt><b><tt>bitcast ( CST to TYPE )</tt></b></dt>
<dd>Convert a constant, CST, to another TYPE. The size of CST and TYPE must be
identical (same number of bits). The conversion is done as if the CST value
was stored to memory and read back as TYPE. In other words, no bits change
with this operator, just the type. This can be used for conversion of
aggregate types to any aggregate type, as long as they have the same bit
width. Vector types may also be casted to and from any other type as long as
they have the same bit width. For pointers it is only valid to cast to
another pointer type.

<dd>Convert a constant, CST, to another TYPE. The constraints of the operands
are the same as those for the <a href="#i_bitcast">bitcast
instruction</a>.</dd>
