--- Comment #11 from Martin Liška <marxin at gcc dot gnu.org> --- (In reply to 康 珊 from comment #10) > Hi Martin Liška, I tried to build it with "-O3 -fno-strict-aliasing > -falign-functions=32 -fno-math-errno -fno-semantic-interposition > -fno-trapping-math", but it still had the issue. Can "-fno-strict-aliasing" > work normally with "-O3"? Yes, it should normally work. So the build is done w/o LTO, right?
