--- Comment #4 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
I can reproduce this on an normal arm-eabi cross compiler with

$build/gcc/xgcc -B$build/gcc/ $src/gcc/testsuite/gcc.dg/vect/pr65947-13.c
-mbig-endian -march=armv7-a+simd -fdiagnostics-plain-output -mfloat-abi=softfp
-ffast-math -ftree-vectorize -fno-tree-loop-distribute-patterns
-fno-vect-cost-model -fno-common -O2 -fdump-tree-vect-details --param
vect-epilogues-nomask=0 -S -isystem
$build/arm-eabi/thumb/v7-a/nofp/newlib/targ-include -isystem
$src/newlib/libc/include -o pr65947-13.s

The test expects "LOOP VECTORIZED" to appear twice in the dump file, but it
only appears once.
