I found that some tests from vect.exp has status UNRESOLVED in cureent compiler version due to dissynchronization of compiler dumpers and tests check.

Example:
Test bb-slp-10.c awaits for name
bb-slp-10.c.124t.slp
but it gets this
bb-slp-10.c.124t.slp2

Open bb-slp-10.c

Change "slp" to "slp2" in
...
/* { dg-final { scan-tree-dump-times "unsupported alignment in basic block." 1 "slp" { xfail vect_element_align } } } */
/* { dg-final { scan-tree-dump-times "basic block vectorized using SLP" 1 "slp" { target vect_element_align } } } */

Test will pass or at least it won't have UNRESOLVED status.

Another UNRESOLVED example vect-105-big-array.c and generaly all tests with scan-tree-dump-times and -flto option. 

-flto makes gcc to create file with name
vect-105-big-array.exe.ltrans0.114t.vect

Which is obviosly not supported too.

Configuration:

Run tests:

make -k check RUNTESTFLAGS='vect.exp'
