When I try compiling with -mstackrealign -mpreferred-stack-boundary=3D5 -mincoming-stack-boundary=3D5 instead of forcing unaligned moves I get "cc1= .exe: error: '-mpreferred-stack-boundary=3D5' is not between 3 and 4". Is that th= is bug in a different form, something that should be filed separately, or known and intended behavior?=
