--- Comment #4 from Andreas Krebbel <krebbel at gcc dot gnu.org> --- The problem occurs starting with: commit 1e1e1edf88a7c40ae4ae0de9e6077179e13ccf6d Author: Richard Biener <rguent...@suse.de> Date: Thu Oct 29 08:48:15 2020 +0100 More BB vectorization tweaks This tweaks the op build from splats to allow loads marked as not vectorizable. It also amends some dump prints with the address of the SLP node or the instance to better be able to debug things. 2020-10-29 Richard Biener <rguent...@suse.de> * tree-vect-slp.c (vect_build_slp_tree_2): Allow splatting not vectorizable loads. (vect_build_slp_instance): Amend dumping with address. (vect_slp_convert_to_external): Likewise. * gcc.dg/vect/bb-slp-pr65935.c: Adjust.
