Hi!

OK to push the attached "GCN: Enable effective-target 'vect_long_mult'"?
(Or is that not what you'd expect to see for GCN?  I haven't checked the
actual back end code...)


Grüße
 Thomas

Subject: [PATCH] GCN: Enable effective-target 'vect_long_mult'

... as made apparent by commit bfd6b36f08021f023e0e9223f5aea315b74a5c56
"testsuite/vect: Fix pr25413a.c expectations [PR109705]" causing:

     PASS: gcc.dg/vect/pr25413a.c (test for excess errors)
     PASS: gcc.dg/vect/pr25413a.c execution test
    -PASS: gcc.dg/vect/pr25413a.c scan-tree-dump-times vect "vectorized 2 loops" 1
    +FAIL: gcc.dg/vect/pr25413a.c scan-tree-dump-times vect "vectorized 1 loops" 1

..., which this commit resolves.
