            Bug ID: 42185
           Summary: [docs]Add missing options/behaviour to llvm-dwarfdump
           Product: tools
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: llvm-dwarfdump
          Assignee: unassignedbugs at nondot.org

There are quite a few options visible in the llvm-dwarfdump help text that are
missing from the online documentation. It looks like it was mostly an oversight
with the DWARF 5 work, but not exclusively so. Here is the list that I found:

--help-list (--help is present, so --help-list probably should be too)

Additionally, there is no reference in the document to the ability to pass
options via response files (i.e. "llvm-dwarfdump @response.txt", where
response.txt contains a list of options to provide the tool).

The document also doesn't mention that a.out is used as a default input, nor
that '-' means read from stdin (or write to stdout for the --out-file option).
