--- Comment #8 from Martin Liška <marxin at gcc dot gnu.org> --- (In reply to Eric Botcazou from comment #7) > Not a regression since #pragma GCC unroll is new. Note that https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85964#c2 provides test-case that does not use GCC unroll. I see following starting revision with following timeouts: 5s: r250338 10s: r250338 20s: r254379 That said I would classify that as regression.
