--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
OK, so we're having memory_access_type == VMAT_GATHER_SCATTER, gs_info.ifn !=
IFN_LAST but STMT_VINFO_GATHER_SCATTER_P is false. It looks like vec_offset is
set elsewhere in that case. Likely here:
else if (memory_access_type == VMAT_GATHER_SCATTER)
{
aggr_type = elem_type;
vect_get_strided_load_store_ops (stmt_info, loop_vinfo, &gs_info,
&bump, &vec_offset);
}
so the fix is to re-instante the guard, doing
diff --git a/gcc/tree-vect-stmts.c b/gcc/tree-vect-stmts.c
index ab402b57fb4..cc6c091e41e 100644
--- a/gcc/tree-vect-stmts.c
+++ b/gcc/tree-vect-stmts.c
@@ -9492,7 +9492,8 @@ vectorizable_load (vec_info *vinfo,
if (memory_access_type == VMAT_GATHER_SCATTER
&& gs_info.ifn != IFN_LAST)

- vec_offset = vec_offsets[j];

will push this as obvious.

tree-optimization/101861 - fix gather use for non-gather refs
My previous change broke the usage of gather for strided loads.
The following fixes it.
