## Use llvm-dwarfdump to check the integrity of the inlined function "bar"
## DWARF range after llvm-bolt removes a 6-byte nop instruction.
##
## If the range is not properly updated, it will exceed the range of the
## containing function causing llvm-dwarfdump to issue an error.
# CHECK-NOT: error: DIE address ranges are not contained in its parent's ranges
# REQUIRES: system-linux
