--- Comment #42 from Markus Trippelsdorf <trippels at gcc dot gnu.org> --- (In reply to Sven C. Dack from comment #40) > The results are the averages (and deviations) of 5 runs with each compiler: > > avg stdev % > default: 282.86s 0.56s, 0.20% 100.00% (base) > profiled: 255.76s 0.72s, 0.28% +10.60% > lto: 282.80s 0.16s, 0.06% +0.02% > lto-plugin: 285.41s 0.49s, 0.17% -0.89% Can you also try profiled+lto? This should in theory get you the fastes compiler.
