             Bug #: 50629
           Summary: [4.7 Regression] FAIL:
                    gcc.c-torture/execute/vect-shuffle-2.c with ICE on ARM
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

+++ This bug was initially created as a clone of Bug #50607 +++

Recently added regression tests fail on arm:
FAIL: gcc.c-torture/execute/vect-shuffle-2.c compilation,  -O1  (internal
compiler error)

The tests vect-shuffle-2.c and vect-shuffle-5.c fail with ICE at all
optimization levels above -O0 on arm-eabi. Other vect-shuffle-*.c tests pass.
ICE is a segfault in expand_vec_shuffle_expr (optabs.c:6660), here are the
details:

$ arm-eabi-gcc vect-shuffle-2.c  -O1 -c 

vect-shuffle-2.c: In function 'main':
vect-shuffle-2.c:30:8: internal compiler error: Segmentation fault

Trunk revision r179558.
Configured with: --with-cpu=cortex-a9 --with-float=softfp --with-fpu=neon 
--target=arm-eabi

These tests are not in the repository anymore.  Please update your sources and
see if the bunch of tests gcc.c.torture/execute/vshuff-* bring any failures.

Thanks,
Artem.

These tests no longer exist in the repository and have been reworked. 

This is thus invalid.
