Re: [PATCH, GDB] Expect prompt after no FPU warning


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

    * gdb.base/float.exp (info float): Expect GDB prompt for ARM

Remove " (info float)".

    targets without FPU.

The fix is right but it can be applied to all archs which may not have
FPU.  If you search "N floating.point info", you can find multiple hits.
$gdb_prompt is needed for all of them.

Err yes sorry, I didn't add it because I only tested on ARM. I'll update the
patch. Thanks!

Best regards,
