> The Debian-Ports "powerpcspe" architecture can't currently build the
> libffi package for a couple reasons:
>
>  (1) The package contains lots of FP assembly instructions even when
>      built on a soft-float target, resulting in compile errors on the
>      Debian powerpcspe architecture (totally different FPU ops).
>
>  (2) The existing soft-float support code has buggy handling of 128-bit
>      values and results in testsuite failures on soft-float and e500
>      (powerpcspe) platforms even when it can be made to compile.
>
> The attached patch resolves both issues.
