libstdc++: Use __builtin_shufflevector for simd split and concat
Signed-off-by: Matthias Kretz <m.kretz@gsi.de>
libstdc++-v3/ChangeLog:
PR libstdc++/114958
* include/experimental/bits/simd.h (__as_vector): Return scalar
simd as one-element vector. Return vector from single-vector
fixed_size simd.
(__vec_shuffle): New.
(__extract_part): Adjust return type signature.
(split): Use __extract_part for any split into non-fixed_size
simds.
(concat): If the return type stores a single vector, use
__vec_shuffle (which calls __builtin_shufflevector) to produce
the return value.
* include/experimental/bits/simd_builtin.h
(__shift_elements_right): Removed.
(__extract_part): Return single elements directly. Use
__vec_shuffle (which calls __builtin_shufflevector) to for all
non-trivial cases.
* include/experimental/bits/simd_fixed_size.h (__extract_part):
Return single elements directly.
* testsuite/experimental/simd/pr114958.cc: New test.
