Hmm, trunk has { xfail vect_load_lanes } there, but the GCC 10 branch also
misses that. Can you check if the GCC 10 branch also sees this FAIL and
if adding the XFAIL helps?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96075 --- Comment #15 from Christophe Lyon --- Yes, the test fails on gcc-10 too. I tried adding xfail vect_load_lanes in gcc-9, and it correctly makes the test XFAIL.
