<h5>Syntax:</h5>
<p>This is an overloaded intrinsic. You can use <tt>llvm.bit.part_set</tt> on
any integer bit width.
<pre>
declare i17 @llvm.bit.part_set.i17.i17.i9 (i17 %val, i32 %bit, i9 %newbits)
declare i29 @llvm.bit.part_set.i29.i29.i13(i29 %val, i32 %bit, i13 %newbits)
</pre>
<h5>Overview:</h5>
<p>The '<tt>llvm.bit.part_set</tt>' family of intrinsic functions sets a range
of bits in a given value to a new value and returns the result.</p>
<h5>Arguments:</h5>
<p>The first argument and the result may be an integer type of any bit width but
they must have the same bit width. The second argument must be an <tt>i32</tt>.
The third argument may be any any bit width less than or equal to the bit width
of the first argument.</p>
<h5>Semantics:</h5>
<p>The '<tt>llvm.bit.part_set</tt>' intrinsic sets the value given by
<tt>%newbits</tt> into <tt>%val</tt> at the bit index given by <tt>%bit</tt>.
This is equivalent to the following sequence:</p>
<ol>
<li>The bits in <tt>%val</tt> starting at <tt>%bit</tt> and up to the width
of <tt>%newbits</tt> are cleared by ANDing them with a zero mask.</li>
<li>The bits in <tt>%newbits</tt> are shifted left by <tt>%bit</tt> bits.
<li>The shifted <tt>%newbits</tt> value is OR'd into <tt>%val</tt> to produce
the result.</li>
</ol>
