<h5>Syntax:</h5>
|
||||
<pre>
|
||||
declare i32 @llvm.expect.i32(i32 <val>, i32 <expected_val>)
|
||||
declare i64 @llvm.expect.i64(i64 <val>, i64 <expected_val>)
|
||||
</pre>
|
||||
|
||||
<h5>Overview:</h5>
|
||||
<p>The <tt>llvm.expect</tt> intrinsic provides information about expected (the
|
||||
most probable) value of <tt>val</tt>, which can be used by optimizers.</p>
|
||||
|
||||
<h5>Arguments:</h5>
|
||||
<p>The <tt>llvm.expect</tt> intrinsic takes two arguments. The first
|
||||
argument is a value. The second argument is an expected value, this needs to
|
||||
be a constant value, variables are not allowed.</p>
|
||||
|
||||
<h5>Semantics:</h5>
|
||||
<p>This intrinsic is lowered to the <tt>val</tt>.</p>
