--- Comment #28 from Tamar Christina <tnfchris at gcc dot gnu.org> --- (In reply to pthaugen from comment #19) > I tried -fno-inline-functions-called-once and the patches on a Power9 > system. Following are the run times and spill counts (grep -c Spilling > exchange2.fppized.f90.298r.ira). Interesting that the spill counts increase > when -fno-inline-functions-called-once is added, but obviously that > additional spill is on cold paths since execution time improves. Compiler > options used are "-O3 -mcpu=power9 -fpeel-loops -funroll-loops -ffast-math". > > time(sec) Spill > base 473 3284 > > no-inline-functions-called-once 370 5410 > > patches 1 & 2 397 461 > > patches 1 & 2 > + no-inline-functions-called-once 299 870 Ah thanks for testing!, so at least we know that all architectures are suffering from the same underlying issue :)
