; The test case is buggy, it supposed to check that we reject memcpy with vector
|
|
; pointer arguments. Now we don't reject such memcpy and the test case would
|
|
; fail if it was correct. Because it used the wrong signature for memcpy (the
|
|
; last isVolatile argument was missing) it was rejected by the verifier and
|
|
; didn't fail. Fix the memcpy signature and mark it as an expected failure
|
|
; for now.
