Option parsing: allow aliases in groups Option aliases in option groups were previously disallowed by an assert. As far as I can tell, there was no technical reason for this, and I would like to be able to put cl.exe compatible options in their own group for Clang, so let's change the assert. llvm-svn: 186838

Option parsing: add support for alias arguments. This makes option aliases more powerful by enabling them to pass along arguments to the option they're aliasing. For example, if we have a joined option "-foo=", we can now specify a flag option "-bar" to be an alias of that, with the argument "baz". This is especially useful for the cl.exe compatible clang driver, where many options are aliases. For example, this patch enables us to alias "/Ox" to "-O3" (-O is a joined option), and "/WX" to "-Werror" (again, -W is a joined option).

Options: Add new option kind that consumes remaining arguments This adds KIND_REMAINING_ARGS, a class of options that consume all remaining arguments on the command line. This will be used to support /link in clang-cl, which is used to forward all remaining arguments to the linker. It also allows us to remove the hard-coded handling of "--", allowing clients (clang and lld) to implement that functionality themselves with this new option class.

Option parsing: properly handle flag aliases for joined options (PR23394) A joined option always needs to have an argument, even if it's an empty one. Clang would previously assert when trying to use --extra-warnings, which is a flag alias for -W, which is a joined option. llvm-svn: 236434

[Option] Add 'findNearest' method to catch typos Summary: Add a method `OptTable::findNearest`, which allows users of OptTable to check user input for misspelled options. In addition, have llvm-mt check for misspelled options. For example, if a user invokes `llvm-mt /oyt:foo`, the error message will indicate that while an option named `/oyt:` does not exist, `/out:` does. The method ports the functionality of the `LookupNearestOption` method from LLVM CommandLine to libLLVMOption. This allows tools like Clang and Swift, which do not use CommandLine, to use this functionality to suggest similarly spelled options. As room for future improvement, the new method as-is cannot yet properly suggest nearby "joined" options -- that is, for an option string "-FozBar", where "-Foo" is the correct option name and "Bar" is the value being passed along with the misspelled option, this method will calculate an edit distance of 4, by deleting "Bar" and changing "z" to "o". It should instead calculate an edit distance of just 1, by changing "z" to "o" and recognizing "Bar" as a value. This commit includes a disabled test that expresses this limitation.

[Option] For typo '-foo', suggest '--foo' Summary: https://reviews.llvm.org/rL321877 introduced the `OptTable::findNearest` method, to find the closest edit distance option for a given string. However, the implementation contained a bug: for a typo `-foo` with an edit distance of 1 away from a valid option `--foo`, `findNearest` would suggest a nearby option of `foo`. That is, the result would not include the `--` prefix, and so was not a valid option. Fix the bug by ensuring that the prefix string is initialized to one of the valid prefixes for the option.
