[PATCH 0/5] gdb/testsuite: stricter matching for gdb_test

[Andrew Burgess <aburgess@redhat.com>]

The goal of this series is to make the pattern matching in gdb_test
stricter with respect to end of line sequences.  This encourages us
all to be a little more precise when writting the output patterns for
use in gdb_test, but I think this is a good thing for GDB - our tests
will get a little stricter.

The final patch adds a new feature to gdb_test, a modified version of
the '^' anchor, which again, should (I hope) allow us to write
stricter output patterns, which I think is a good thing for GDB.

Thanks,
Andrew
