# Test to check if machine function splitter still produces the right backtraces
|
|
# with lldb when a function is split into a hot and cold part and the cold part
|
|
# is executed. The cold part has the same function symbol name but with a
|
|
# ".cold" suffix and this test checks that the back trace is clear.
