Alex Brachet 60c81354b1 [tools] [llvm-nm] Default to reading from stdin not a.out
Summary: This moves away from defaulting to a.out and uses stdin only if stdin has a file redirected to it. This has been discussed on the llvm-dev mailing list [[ https://lists.llvm.org/pipermail/llvm-dev/2019-July/133642.html | here ]].

James Henderson 90c57e0001 [docs][llvm-readelf] Expand llvm-readelf documentation
Previously, the llvm-readelf documentation was essentially just a list
of differences to llvm-readobj. Since llvm-readelf is the more likely
goto tool for many people migrating to the LLVM toolchain, it seems like
it would be helpful to document all the switches in the llvm-readelf
document too. This change expands the options listed accordingly.
Additionally, they are unlikely to care what the differences are to
llvm-readobj, since they won't be familiar with the latter as there is
no GNU equivalent, so this change moves the "differences" section to
llvm-readobj's documentation.

James Henderson a056684c33 [docs][tools] Add missing "program" tags to rst files
Sphinx allows for definitions of command-line options using
`.. option <name>` and references to those options via `:option:<name>`.
However, it looks like there is no scoping of these options by default,
meaning that links can end up pointing to incorrect documents. See for
example the llvm-mca document, which contains references to -o that,
prior to this patch, pointed to a different document. What's worse is
that these links appear to be non-deterministic in which one is picked
(on my machine, some references end up pointing to opt, whereas on the
live docs, they point to llvm-dwarfdump, for example).

The fix is to add the .. program <name> tag. This essentially namespaces
the options (definitions and references) to the named program, ensuring
that the links are kept correct.

them by:

 1. Adding [addresses...] to the synopsis, and matching the formatting
    of other tools.
 2. Rewriting the description to fix grammar issues and mention other
    usage options.
 3. Rewriting the examples to be easier to read.
 4. Re-ordering the options into alphabetical order.
 5. Improving the text of some of the option descriptions, and adding
    some examples to individual options.
 6. Splitting the Mach-O options into a separate section of the
    document.
 7. Standardizing on double dashes for long options throughout the file.
 8. Adding a reference to the llvm-addr2line document.

James Henderson b96d9d8bda [docs][llvm-readobj] Improve llvm-readobj documentation
There were a number of issues with the llvm-readobj documentation. The
following points were raised in https://bugs.llvm.org/show_bug.cgi?id=42255,
and have been fixed in this patch:

 1. The description section claimed "The tool and its output is
    primarily designed for use in FileCheck-based tests" which is not
    really the case any more.
 2. The documentation used single-dash long options for option names,
    but references in the help text to other options exclusively used
    double-dashes. Fixed by standardising on double-dashes for all
    long-form options.
 3. The majority of options available and in the help text were not
    present in the documentation. This patch adds them.
 4. Several aliases, both long and short, were missing, e.g. --relocs.

Additionally, this patch improves the documentation by:

 1. Splitting the options into categories based on the file format they
    are specific to.
 2. Updating the Exit Status section to correctly mention that errors
    lead to a non-zero exit code.
 3. Adding a See Also section referencing other similar LLVM tools.
 4. Improving/correcting some of the descriptions of options that did
    not quite match up with what llvm-readobj does.
