## Check that the --debug-vars option works for simple register locations, when
## using DWARF4 debug info, with multiple functions in one section. Check that
## the live-range lines are rendered correctly when using the --no-show-raw-insn,
## --line-numbers and --source options. These do not affect the DWARF parsing
## used by --debug-vars, but do add extra lines or columns to the output, so we
## test to make sure the live ranges are still displayed correctly.
