[AArch64][SVE] Unable to widen vector store #54424
Description
add <vscale x 3 x i64> https://godbolt.org/z/cM9YMqEc4
define <vscale x 3 x i64> @add_i64_nxv3(<vscale x 3 x i64> %a0, <vscale x 3 x i64> %a1) #0 {
%1 = add nsw <vscale x 3 x i64> %a0, %a1
ret <vscale x 3 x i64> %1
}
Crashes with target triple = "aarch64-linux-gnu" -mattr=+sve2 -O3
The same occurs with sub and mul
