<h5>Syntax:</h5>
|
||||
<p>This is an overloaded intrinsic. You can use <tt>llvm.floor</tt> on any
|
||||
floating point or vector of floating point type. Not all targets support all
|
||||
types however.</p>
|
||||
|
||||
<pre>
|
||||
declare float @llvm.floor.f32(float %Val)
|
||||
declare double @llvm.floor.f64(double %Val)
|
||||
declare x86_fp80 @llvm.floor.f80(x86_fp80 %Val)
|
||||
declare fp128 @llvm.floor.f128(fp128 %Val)
|
||||
declare ppc_fp128 @llvm.floor.ppcf128(ppc_fp128 %Val)
|
||||
</pre>
|
||||
|
||||
<h5>Overview:</h5>
|
||||
<p>The '<tt>llvm.floor.*</tt>' intrinsics return the floor of
|
||||
the operand.</p>
|
||||
|
||||
<h5>Arguments:</h5>
|
||||
<p>The argument and return value are floating point numbers of the same
|
||||
type.</p>
|
||||
|
||||
<h5>Semantics:</h5>
|
||||
<p>This function returns the same values as the libm <tt>floor</tt> functions
|
||||
would, and handles error conditions in the same way.</p>
