# Test for warnings when placing yield instructions into IQ2000's
# branch delay slot. Written by Ben Elliston (bje@redhat.com)
# Run GAS and check that it emits the desired warning for the test case.
# Arguments:
# file -- name of the test case to assemble.
# testname -- a string describing the test.
# warnpattern -- a regular expression, suitable for use by the Tcl
# regexp command, to decide if the warning string was emitted by
# the assembler to stderr.
