# Note:
# Occasionally we run into PR28561 - "[gdb/testsuite] Error due to not
# reading \r\n at end of mi prompt".
# https://sourceware.org/bugzilla/show_bug.cgi?id=28561
# Not sure how to filter for that.

# TODO:
#
# We run into FAILs like this:
# FAIL: gdb.base/options.exp: test-print: \
#   tab complete "thread apply all print " (clearing input line) (timeout)
# FAIL: gdb.base/options.exp: test-print: \
#   cmd complete "thread apply all print "
# in various test-cases.  One instance is reported here (
# https://sourceware.org/bugzilla/show_bug.cgi?id=27813 ).
# We could do a generic kfail for "(clearing input line) (timeout)", but that
# doesn't filter out the following FAIL.  We need to update the testsuite to
# emit only one FAIL for this, or alternatively, add a possibility in this
# script to KFAIL one and all following FAILs in the same test-case.
