--- Comment #21 from Richard Biener <rguenth at gcc dot gnu.org> ---
(In reply to Uro=C5=A1 Bizjak from comment #20)
> Can we revert the Comment #13 kludge now?

When we revert it we get

17%)
   19M ( 16%)
 LRA non-specific                   :   0.39 ( 16%)   0.00 (  0%)   0.39 ( =

 6304k (  5%)
 LRA virtuals elimination           :   0.03 (  1%)   0.00 (  0%)   0.02 ( =

 LRA create live ranges             :   0.27 ( 11%)   0.00 (  0%)   0.28 ( =

 LRA hard reg assignment            :   0.72 ( 30%)   0.01 ( 10%)   0.74 ( =

    0  (  0%)
 TOTAL                              :   2.43          0.10          2.54=20=
=20=20=20=20=20=20
  123M

so the regression is back and also code size increases significantly.=
