Hi
Current AArch64 backend can generate rtl expressions like
(vec_duplicate:DI (const_int 0 [0])), which causes ICE in
simplify_const_unary_operation because vec_duplicate should generate
vector mode only.
As suggested by Andrew in the bug entry, I split the original insn
patterns to avoid scalar mode vec_duplicate expression.
The documentation does say that vec_concat can work on scalars, so it
seems ok to me at a glance (but I can't approve it myself).
Would be nice to have an addition to the testsuite though...
Kyrill
Passed regression tests on qemu without failure.
OK for trunk and 4.9 branch?
thanks
