* [DebugInfo] Only print a single blank line after an empty line tableJames Henderson2019-12-171-2/+29
| | | | | | | | | | | | Commit 84a9756 added an extra blank line at the end of any line table. However, a blank line is also printed after the line table header, which meant that two blank lines in a row were being printed after a header, if there were no rows. This patch defers the post-header blank line printing until it has been determined that there are rows to print. Reviewed by: dblaikie Differential Revision: https://reviews.llvm.org/D71540

* [test][llvm-dwarfdump] Add missing testing for some --debug-* optionsJames Henderson2019-12-111-0/+144
A number of the --debug-* options in llvm-dwarfdump are not particularly well tested. In some cases, the option is only tested as part of testing another feature, or a specific part of the section that the options dump. This change adds four new tests to address some of these holes. It is not aiming to address every hole however. I kept the --debug-line switch test separate to X86/brief.s because the latter only considers the parts of the line table that are affected by verbose printing, thus missing out things like the header and different values for things like the Line, Column etc registers.
