--- Comment #1 from luoxhu at gcc dot gnu.org ---
Confirmed, I will fix it.
Actually I have pending patch not committed yet. [PATCH 2/4] which generate
VIEW_CONVERT_EXPR is not committed, but V2DF VIEW_CONVERT_EXPR will be convert
to IFN VEC_SET in gimple-isel now which caused the ICE.
VIEW_CONVERT_EXPR<double[2]>(t)[i_12] = x_6(D);
(https://gcc.gnu.org/pipermail/gcc-patches/2020-October/555906.html)
IFN VEC_SET is not expanded on Power8 yet, [PATCH 3/4] could fix this. Need
Segher's approval.

I cannot reproduce it w/ gcc-11.0.0-alpha20210131 snapshot
(g:98342bdd2b7085c9e7e4c9fbb07c3917a0013515). However, the issue is still
there.

It's fixed on master, can we close it now or do we need a backport to active
branches?

If someone filled in the known-to-work / known-to-fail fields we would know!
