Digging in history reveals the testcases were added by
Jiangning Liu <jiangning....@arm.com>, not for any
particular bugreport but "The problem is originally from a real benchmark,
and the test case only tries to detect the GIMPLE level changes."
I'm not sure we can infer the testcase should be moved to
gcc.target/arm/ because of that, but it does seem plausible.
I read from your messages that the testcases pass on arm*-*-*?
