##===- TEST.optllcdbg.Makefile -----------------------------*- Makefile -*-===##
#
# This test checks whether presence of debug declarations influences
# the code generator or not.
#
# If input.bc includes llvm.dbg intrinsics and llvm.dbg variables then
# the code in first.s and second.s should match. Otherwise debugging information
# is influencing the code generator. The Dwarf info in first.s and second.s is
# normally quite different, so the data directives that appear in Dwarf are
# stripped out before comparison.
#
# This has only been used on Darwin; the data directives to strip and grep magic
# might be different elsewhere.
