[OptTable] Support grouped short options POSIX.1-2017 12.2 Utility Syntax Guidelines, Guideline 5 says: > One or more options without option-arguments, followed by at most one option that takes an option-argument, should be accepted when grouped behind one '-' delimiter. i.e. -abc represents -a -b -c. The grouped short options are very common. Many utilities extend the syntax by allowing (an option with an argument) following a sequence of short options. This patch adds the support to OptTable, similar to cl::Group for CommandLine (D58711). llvm-symbolizer will use the feature (D83530). CommandLine is exotic in some aspects. OptTable is preferred if the user wants to get rid of the behaviors. * `cl::opt<bool> i(...)` can be disabled via -i=false or -i=0, which is different from conventional --no-i. * Handling --foo & --no-foo requires a comparison of argument positions, which is a bit clumsy in user code. OptTable::parseOneArg (non-const reference InputArgList) is added along with ParseOneArg (const ArgList &). The duplicate does not look great at first glance. However, The implementation can be simpler if ArgList is mutable. (ParseOneArg is used by clang-cl (FlagsToInclude/FlagsToExclude) and lld COFF (case-insensitive). Adding grouped short options can make the function even more complex.) The implementation allows a long option following a group of short options. We probably should refine the code to disallow this in the future. Allowing this seems benign for now. Reviewed By: grimar, jhenderson Differential Revision: https://reviews.llvm.org/D83639

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.

Re-reland "[Option] Fix PR37006 prefix choice in findNearest" This was first reviewed in https://reviews.llvm.org/D46776 and landed in r332299, but got reverted because it broke the PS4 bots. https://reviews.llvm.org/D50410 fixed this, and then this change was re-reviewed at https://reviews.llvm.org/D50515 and relanded in r341329. It got reverted due to causing MSan issues. However, nobody wrote down the error message and the bot link is dead, so I'm relanding this to capture the MSan error. I'll then either fix it, or copy it somewhere and revert if fixing looks difficult. llvm-svn: 359580

[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.

Fix OptTable::findNearest() adding delimiter for free Prior to this, OptTable::findNearest() thought that the input `--foo` had an editing distance of 0 from an existing flag `--foo=`, which made it suggest flags with delimiters more often than flags without one. After this, it correctly assigns this case an editing distance of 1. Differential Revision: https://reviews.llvm.org/D61373 llvm-svn: 359685

Option spell checking: Penalize delimiter flags if input has no argument If the user passes a flag like `-version` to a program, it's more likely they mean `--version` than `-version:`, since there's no parameter passed. Hence, give delimited arguments a penalty of 1 if the user input doesn't contain the delimiter or no data after it. The motivation is that with this, lld-link can suggest "--version" instead of "-version:" for "-version" and "-nodefaultlib" instead of "-nodefaultlib:" for "-nodefaultlibs".

Port some floating point options to new option marshalling infrastructure This ports a number of OpenCL and fast-math flags for floating point over to the new marshalling infrastructure. As part of this, `Opt{In,Out}FFlag` were enhanced to allow other flags to imply them, via `DefaultAnyOf<>`. For example: ``` defm signed_zeros : OptOutFFlag<"signed-zeros", ..., "LangOpts->NoSignedZero", DefaultAnyOf<[cl_no_signed_zeros, menable_unsafe_fp_math]>>; ``` defines `-fsigned-zeros` (`false`) and `-fno-signed-zeros` (`true`) linked to the keypath `LangOpts->NoSignedZero`, defaulting to `false`, but set to `true` implicitly if one of `-cl-no-signed-zeros` or `-menable-unsafe-fp-math` is on. Note that the initial patch was written Daniel Grumberg. Differential Revision: https://reviews.llvm.org/D82756
