* Handle consecutive-double-quotes in Windows argument parsingSunil Srivastava2019-03-141-1/+8
| | | | | | | | | Windows command line argument processing treats consecutive double quotes as a single double-quote. This patch implements this functionality. Differential Revision: https://reviews.llvm.org/D58662 llvm-svn: 356193
* [CommandLine] Allow grouping options which can have values.Igor Kudrin2019-03-011-1/+172
| | | | | | | | | | | | | | | | This patch allows all forms of values for options to be used at the end of a group. With the fix, it is possible to follow the way GNU binutils tools handle grouping options better. For example, the -j option can be used with objdump in any of the following ways: $ objdump -d -j .text a.o $ objdump -d -j.text a.o $ objdump -dj .text a.o $ objdump -dj.text a.o Differential Revision: https://reviews.llvm.org/D58711 llvm-svn: 355185
* [CommandLine] Do not crash if an option has both ValueRequired and Grouping.Igor Kudrin2019-03-011-0/+22
| | | | | | | | | | | | If an option, which requires a value, has a `cl::Grouping` formatting modifier, it works well as far as it is used at the end of a group, or as a separate argument. However, if the option appears accidentally in the middle of a group, the program just crashes. This patch prints an error message instead.

The latter version then lists the allowed values after it. 2) Empty-named values with no help text in ValueOptional options are not listed in the permitted values. -some-option - some help text -some-option=<value> - some help text =v1 - description 1 =v2 - description 2 3) Otherwise empty-named options are printed as =<empty> rather than simply '='. 4) Option values without help text do not have the '-' separator printed. -some-option=<value> - some help text =v1 - description 1 =v2 =<empty> - description It also tweaks the llvm-symbolizer -functions help text to not print a trailing ':' as that looks bad combined with 1) above.

* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3

We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

* [CommandLine] Error message for incorrect PositionalEatArgs usageKeno Fischer2018-05-141-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: bugpoint has several options specified as `PositionalEatArgs` to pass options through to the underlying tool, e.g. `-tool-args`. The `-help` message suggests the usage is: `-tool-args=<string>`. However, this is misleading, because that's not how these arguments work. Rather than taking a value, the option consumes all positional arguments until the next recognized option (or all arguments if `--` is specified at some point). To make this slightly clearer, instead print the help as: ``` -tool-args <string>... - <tool arguments>... ``` Additionally, add an error if the user attempts to use a `PositionalEatArgs` argument with a value, instead of silently ignoring it. Example: ``` ./bin/bugpoint -tool-args=-mpcu=skylake-avx512 bugpoint: for the -tool-args option: This argument does not take a value. Instead, it consumes any positional arguments until the next recognized option. ``` Reviewed By: aprantl Differential Revision: https://reviews.llvm.org/D46787 llvm-svn: 332311

* Resubmit "Update llvm command line parser to support subcommands."Zachary Turner2016-06-291-3/+213
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes an issue where occurrence counts would be unexpectedly reset when parsing different parts of a command line multiple times. **ORIGINAL COMMIT MESSAGE** This allows command line tools to use syntaxes like the following: llvm-foo.exe command1 -o1 -o2 llvm-foo.exe command2 -p1 -p2 Where command1 and command2 contain completely different sets of valid options. This is backwards compatible with previous uses of llvm cl which did not support subcommands, as any option which specifies no optional subcommand (e.g. all existing code) goes into a special "top level" subcommand that expects dashed options to appear immediately after the program name. For example, code which is subcommand unaware would generate a command line such as the following, where no subcommand is specified: llvm-foo.exe -q1 -q2 The top level subcommand can co-exist with actual subcommands, as it is implemented as an actual subcommand which is searched if no explicit subcommand is specified. So llvm-foo.exe as specified above could be written so as to support all three aforementioned command lines simultaneously. There is one additional "special" subcommand called AllSubCommands, which can be used to inject an option into every subcommand. This is useful to support things like help, so that commands such as: llvm-foo.exe --help llvm-foo.exe command1 --help llvm-foo.exe command2 --help All work and display the help for the selected subcommand without having to explicitly go and write code to handle each one separately. This patch is submitted without an example of anything actually using subcommands, but a followup patch will convert the llvm-pdbdump tool to use subcommands. Reviewed By: beanz llvm-svn: 274171

* Use gcc's rules for parsing gcc-style response filesNico Weber2016-04-261-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | In gcc, \ escapes every character in response files. It is true that this makes it harder to mention Windows files in rsp files, but not doing this means clang disagrees with gcc, and also disagrees with the shell (on non-Windows) which rsp file quoting is supposed to match. clang isn't free to choose what to do here. In general, the idea for response files is to take bits of your command line and write them to a file unchanged, and have things work the same way. Since the command line would've been interpreted by the shell, things in the rsp file need to be subject to the same shell quoting rules. People who want to put Windows-style paths in their response files either need to do any of: * escape their backslashes * or use clang-cl which uses cl.exe/cmd.exe quoting rules * pass --rsp-quoting=windows to clang to tell it to use cl.exe/cmd.exe quoting rules for response files.

| | | | | | | | | | | | | | | | | | | | | Summary: The primary goal of this patch is to remove the need for MarkOptionsChanged(). That goal is accomplished by having addOption and removeOption properly sort the options. This patch puts the new add and remove functionality on a CommandLineParser class that is a placeholder. Some of the functionality in this class will need to be merged into the OptionRegistry, and other bits can hopefully be in a better abstraction. This patch also removes the RegisteredOptionList global, and the need for cl::Option objects to be linked list nodes. The changes in CommandLineTest.cpp are required because these changes shift when we validate that options are not duplicated. Before this change duplicate options were only found during certain cl API calls (like cl::ParseCommandLine). With this change duplicate options are found during option construction.
