--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
We have a sign mismatch here from vectorizing a POINTER_MINUS_EXPR.
(gdb) p debug ((slp_tree)0x39c2970)
pr83329.c:11:6: note: node 0x39c2970 (max_nunits=1, refcnt=1) vector(1) int
pr83329.c:11:6: note: op template: _2 = &g - &f;
pr83329.c:11:6: note: stmt 0 _2 = &g - &f;
pr83329.c:11:6: note: stmt 1 _3 = &e - &f;
pr83329.c:11:6: note: children 0x39c2a00 0x39c2a90
but
(gdb) p debug_gimple_stmt (0x7ffff6fc3dc0)
_24 = VIEW_CONVERT_EXPR<vector(1) unsigned int>(_23);
there's code to handle this but it's conditional on a special case. The fix
is to invoke it generally I think.

tree-optimization/109735 - conversion for vectorized pointer-diff
There's handling in vectorizable_operation for POINTER_DIFF_EXPR
requiring conversion of the result of the unsigned operation to
a signed type. But that's conditional on the "default" kind of
vectorization. In this PR it's shown the emulated vector path
needs it and I think the masked operation case will, too (though
we might eventually never mask an integral MINUS_EXPR). So the
following makes that handling unconditional.
PR tree-optimization/109735
* tree-vect-stmts.cc (vectorizable_operation): Perform
conversion for POINTER_DIFF_EXPR unconditionally.
