Does anyone know if there are xlf options to selectively disable the optimizations of the XL Fortran compiler? I know that hidden options exist - "-qhslft" or "-qopt=3" - so I wonder if there are undocumented others that control optimizer actions. I want to inhibit the removal of dead code so that I can run my version of the Livermore Loops.
