--- Comment #7 from Georg-Johann Lay <gjl at gcc dot gnu.org> --- (In reply to Andreas Schwab from comment #6) > That's what -fno-tree-loop-distribute-patterns is for. So you know the GCC sources and can draw that conclusion. The documentation of -ftree-loop-distribute-patterns does not relate in any way to that. It's impossible to find this option from a problem description.
