Julian Taylor <jtaylor.debian at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jtaylor.debian at gmail dot com --- Comment #1 from Julian Taylor <jtaylor.debian at gmail dot com> --- looks like expected behavior to me, please read: http://gcc.gnu.org/wiki/x87note you may be able to get consistent results by using -mfpmath=sse e.g. clang will always use amd64 mode even on 32 bit, thus probably the same result.
