Hi Christophe,

indeed, but that's not enough: adding
/* { dg-additional-options "-fdump-tree-vect-details" } */
to both affected tests (gcc.dg/vect/bb-slp-over-widen-[12].c) yields
FAIL: gcc.dg/vect/bb-slp-over-widen-1.c -flto -ffat-lto-objects
scan-tree-dump-times vect "basic block vectorized" 2
FAIL: gcc.dg/vect/bb-slp-over-widen-2.c -flto -ffat-lto-objects
scan-tree-dump-times vect "basic block vectorized" 2
on both 32 and 64-bit x86, and the dump contains:
