In the first example you gave, looking at the pattern (no match_dup,

Marcus,
The +& constraint on operand 0 of vec_unpack_trunc_<mode> seems wrong, since
the template does not use the operand as input.
This patch fixes that.
OK for trunk if aarch64 build & regtest succeeds ?
Your patch looks fine, operand 0 isn't used for input. OK assuming no
regression. Did you find this by inspection or is this the cause of
some bug?
Marcus,
I found this by inspection: https://gcc.gnu.org/ml/gcc/2014-07/msg00007.html .
Thanks,
