--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
I don't remember seeing FAIL: gcc.dg/vect/pr97428.c in the precommit CI, this
one should get one SLP instance and seeing zero means it now fails to SLP on
RISC-V. With a cross and rv64gcv I don't see this failure (on top of trunk).
Ah, for me it's XFAILed because of ! vect_hw_misalign - do you use additional
flags? But even adding -mno-strict-align doesn't help.
Oh, the dejagnu harness uses check_effective_target_riscv_v_misalign_ok
which _runs_ a testcase ... which of course fails for my simple cc1 cross
(w/o binutils and w/o qemu set up). Is the precommit CI any better here?
