| ## 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. |
