The above 13.2 results should be "AOSC system default gcc > 13.2" results. Under AOSC system I recompiled official gcc 13.2 source with > the same parameters except for "--with-tune=la664" (changed to > "--with-tune=la464" since gcc 13.2 does not support "LA664" architecture). > The test results from official gcc 13.2 are following: > > -g -Ofast -march=native : 6.54 (400s) > -g -Ofast -march=native -flto: 6.57 (399s) > -g -Ofast -march=la464 : 6.46 (405s) > -g -Ofast -march=la464 -flto : 6.57 (399s) The data of r13.2 I tested is similar to this. I am currently testing gcc with the AOSC patch.
