            Bug ID: 61542
           Summary: [4.8/4.9 Regression] vect-nop-move.c fails on
                    powerpc64le-unknown-linux-gnu
           Product: gcc
           Version: 4.8.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: wschmidt at gcc dot gnu.org

A test case (gcc.dg/vect/vect-nop-move.c) was added in 4.9 that exposes a bug
on PowerPC little endian for extracting an element from a V4SF value.  When
attempting to extract element N, element 3 - N is extracted instead when N <>
3.

--- Comment #1 from Bill Schmidt <wschmidt at gcc dot gnu.org> ---
The bug exists in 4.8 as well, but was not caught with existing tests (we do
have a test that performs vec_extract on V4SF, but unfortunately only tested
element 3).

Why is this a regression?  ppc64le is a new port in 4.8.

--- Comment #3 from Bill Schmidt <wschmidt at gcc dot gnu.org> ---
I suppose it's not.  It looked like a regression at first with the test failing
in 4.9 and not 4.8, but that was due to the test not existing in 4.8.  Fixed.
