--- Comment #5 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- dg-options is absolutely fine in torture directories, as long as the options specified are not among the -O options that the test should be looping over. For example, it's fine for a torture test to specify a -std option, or -D_GNU_SOURCE, or -fsignaling-nans. I don't see any advantage to using dg-additional-options, except in the cases where you have a base set of dg-options and then some target-specific dg-additional-options.
