--- Comment #7 from Daniel Kolesa <gcc at octaforge dot org> --- I just tested this on big-endian ppc64 targeting power4/ppc970; I was able to successfully bootstrap the compiler. It seems this is really specific to LE after all (which makes sense I suppose, considering the affected code appears to be related to VSX?)
