# This test checks whether presence of debugging information influences
# the optimizer or not. 
#
# If input.bc includes llvm.dbg intrinsics and llvm.dbg variables then
# first.bc and second.bc should match. Otherwise debugging information
# is influencing the optimizer.

# $ opt input.bc -strip-nondebug -strip-debug -std-compile-output -strip -o first.bc
# $ opt input.bc -strip-nondebug -std-compile-output -strip-debug -strip -o second.bc
