## Check that llvm-bolt generates a proper error message when ADR instruction
## cannot be relaxed.

# CHECK: BOLT-ERROR: cannot relax ADR in non-simple function _start
## The function contains unknown control flow and llvm-bolt fails to recover
## CFG. As BOLT has to preserve the function layout, the ADR instruction cannot
## be relaxed into ADRP+ADD.
