Summary: [aarch64] ICE: in emit_move_insn, at expr.c:3609

Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target

Storing a single long double in a vector will cause GCC 4.9.2 and GCC 5.0.0 to

a sum(a first, a second) {
^
Please submit a full bug report,
with preprocessed source if appropriate.
On GCC 5.0.0 (F22) it reports expr.c:3601
Any other argument for vector_size seems to work just fine. Tested up to 2048.
