Re: aarch64 gdb failures in testsuite

Following up to my own mail at
ttps://sourceware.org/ml/gdb/2017-07/msg00037.html

It looks like the problem is with the GCC compiler.  If I use
GCC 4.8.4 to run the gdb.base/store.c test case it works,
if I use GCC 5.4.0 it does not.  I actually get around 50 or
more gdb failures when I use GCC 5.4.0 rather than GCC 4.8.0.
I believe that this may be due to aarch64 changing over from
reload to lra during this timeframe.

I have also found that the test case works if I remove the
register keywords from the test.  Apparently the register
keyword is ignored when optimizing but not at -O0.
