## Class IPAPassInlineFunctions

- java.lang.Object
- - org.apache.sysds.hops.ipa.IPAPass
  - - org.apache.sysds.hops.ipa.IPAPassInlineFunctions

-     public class IPAPassInlineFunctions
      extends IPAPass

  This rewrite inlines single statement block functions, which have fewer operations than an internal threshold. Function inlining happens during validate but after rewrites such as constant folding and branch removal there are additional opportunities.
