> Hi,
> This patch changes the return type of __builtin_vsx_scalar_extract_sig
> from const signed long to const signed long long, so that it can be called
> with "-m32/-mpowerpc64" option. The bif needs TARGET_POWERPC64 instead of
> TARGET_64BIT. So the condition check in the expander is changed.

> Bootstrapped and tested on powerpc64-linux BE and LE with no regressions.
> Is this okay for trunk? Any recommendations? Thanks a lot.
