Ah, I misunderstood. For MSYS2, /usr/bin/gcc : without Kai's patch /mingw64/bin/gcc : -mno-align-vector-insn is enabled by default /mingw32/bin/gcc : -mno-align-vector-insn is enabled by default For current cygwin, /usr/bin/gcc (12.4.0-3) : -mno-align-vector-insn is disabled by default /usr/bin/x86_64-w64-mingw32-gcc : without Kai's patch (yet?) /usr/bin/i686-w64-mingw32-gcc : without Kai's patch (yet?) -- Takashi Yano <takashi.y...@nifty.ne.jp> -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
