In this bench we have the following chain of stmts: UMTmk: npart = 16 call driver(Size, Geom, npart, storePsi) driver: call init(Size, Geom, npart, storePsi, & next,omega,abdym,sigvol,qc, & TPSIC,PSIC,PSIB,PSIFP,CUREZ) and we did not see that value 16 for npart has been propagated (if so the innermost loops with npart upper bound will be completely unrolled). If we look at call graph for init we see that it does not have callee in graph: init_.constprop.2/72 (init_.constprop.2) @0x7f0874ee3b90 Type: function Visibility: used_from_other_partition public visibility_specified visibility:hidden References: Referring: Read from file: /tmp/ccGZySlu.ltrans2.o Clone of init_.2535/55 Function flags: analyzed local finalized Called by: ... I put into attachment the whole bench for investigation.
