libstdc++: Avoid MMX return types from __builtin_shufflevector
This resolves a regression on i686 that was introduced with
r15-429-gfb1649f8b4ad50.
Signed-off-by: Matthias Kretz <m.kretz@gsi.de>
libstdc++-v3/ChangeLog:
PR libstdc++/115247
* include/experimental/bits/simd.h (__as_vector): Don't use
vector_size(8) on __i386__.
(__vec_shuffle): Never return MMX vectors, widen to 16 bytes
instead.
(concat): Fix padding calculation to pick up widening logic from
__as_vector.
