    IRBuilderBase& B,
    AttributeList const& Attrs);

Description

Emit a call to the unary function named 'Name' (e.g. 'floor'). This function is known to take a single of type matching 'Op' and returns one value with the same type. If 'Op' is a long double, 'l' is added as the suffix of name, if 'Op' is a float, we add a 'f' suffix.
