That wouldn't be a solution, because gcc needs to deal with older assemblers
that won't have such a change.  I don't have a strong opinion on whether ne=
wer
versions of gas ought to enable all power7 instructions when given -mvsx, b=
ut I
can say that -mvsx followed the precedent of other similar options, eg.
-maltivec, -mlsp, where the option adds instructions for some function unit=
 to
the current cpu supported.=
