Title:
  gcc 4.8: Wrong code for vector doubleword extract

Status in gcc-defaults package in Ubuntu:
  New

Bug description:
  ---Problem Description---
  GCC 4.8 produces wrong code for powerpc64le-*-* when extracting the second doubleword of a V2DF or V2DI vector from memory.  This has been fixed upstream as revision r221696.  The revised test gcc/testsuite/gcc.dg/vmx/extract-vsx.c can be used to verify the problem on an unfixed compiler, and to verify the solution on a fixed one.
    
  Machine Type = POWER8 
   
  ---Steps to Reproduce---
   Compile and run the revised gcc/testsuite/gcc.dg/vmx/extract-vsx.c found in the patch, according to the steps in the test case.

  This bug occurs only in GCC 4.8, so if I understand correctly this
  only affects the 14.04 LTS release.  I would like to request that this
  patch be applied in the next point release for 14.04 LTS.
