# ${tool}_check_unsupported_p -- Check the compiler(/assembler/linker) output
# for text indicating that the testcase should be marked as "unsupported"
#
# When dealing with a large number of tests, it's difficult to weed out the
# ones that are too big for a particular cpu (eg: 16 bit with a small amount
# of memory).  There are various ways to deal with this.  Here's one.
# Fortunately, all of the cases where this is likely to happen will be using
# gld so we can tell what the error text will look like.
