Expect prompt after no FPU warning
Commit Message
Hi,
The expected output for info float when the target has no FPU does
not include the GDB prompt. This occasionally cause a test failure in
the following "finish" test when the prompt happens after the test has been
marked as PASSed, since it does not match the expected output.
This patch adds the GDB prompt to the expected output of the no FPU
regular expression.
ChangeLog entry is as follows:
*** gdb/testsuite/ChangeLog ***
2017-04-27 Thomas Preud'homme <thomas.preudhomme@arm.com>
* gdb.base/float.exp: Expect GDB prompt for targets without FPU.
Testing: test PASSes with that patch on arm-none-eabi target.
Is this ok for master branch and GDB 8 (after a 1 week period)?
Best regards,
Thomas

Patch is good to me, one comment below.
GDB 8 will be released soon, so it is good to have this patch in 8.0.
This patch is about test case, so it should be safe to merge it to 8.0
branch now.

This change is not needed, because $gdb_prompt is appended in the
pattern inside of gdb_test.
