* Options: Use erase_if to remove Args from the list.Benjamin Kramer2014-05-181-8/+3
| | | | | | | While there make getOption return a const reference so we don't have to put it on the stack when calling methods on it. No functionality change. llvm-svn: 209088
* Protect the ArgList dtorDavid Blaikie2014-04-201-5/+0
| | | | | | | | | | | | | It could even be made non-virtual if it weren't for bad compiler warnings. This demonstrates that ArgList objects aren't destroyed polymorphically and possibly that they aren't even used polymorphically. If that's the case, it might be possible to refactor the two ArgList types more separately and simplify the Arg ownership model. *continues experimenting* llvm-svn: 206727
* Use unique_ptr to handle ownership of synthesized args in DerivedArgListDavid Blaikie2014-04-201-27/+26
| | | | | | | | This might be able to be simplified further by using Arg as a value type in a linked list (to maintain pointer validity), but here's something simple to start with. llvm-svn: 206724
* [C++11] More 'nullptr' conversion. In some cases just using a boolean check ↵Craig Topper2014-04-153-24/+24

* Fix another mistake in r190442.Eli Friedman2013-09-101-0/+29

* Option parsing: support case-insensitive option matching.Rui Ueyama2013-08-281-21/+41

* Option parsing: support case-insensitive option matching.Rui Ueyama2013-08-271-34/+48
| | | | | | | | | | | | | | Link.exe's command line options are case-insensitive. This patch adds a new attribute to OptTable to let the option parser to compare options, ignoring case. Command lines are generally case-insensitive on Windows. CL.exe is an exception. So this new attribute should be useful for other commands running on Windows.

* Options: explicit handling of --Hans Wennborg2013-08-131-16/+0
| | | | | | | | | | | Clients of the option parsing library should handle it explicitly using a KIND_REMAINING_ARGS option. Clang and lld have been updated in r188316 and r188318, respectively. Also fix -Wsign-compare warning in the option parsing test. llvm-svn: 188323
* Options: Add new option kind that consumes remaining argumentsHans Wennborg2013-08-132-0/+14
| | | | | | | | | | | | | | | | 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: recognize the special -- tokenHans Wennborg2013-08-021-1/+16
| | | | | | | | | | | | | | Everything that comes after -- should be treated as a filename. This enables passing in filenames that would otherwise be conflated with command-line options. This is especially important for clang-cl which supports options starting with /, which are easily conflatable with Unix-style path names. Differential Revision: http://llvm-reviews.chandlerc.com/D1274 llvm-svn: 187675
* Option parsing: add support for alias arguments.Hans Wennborg2013-07-311-2/+20
| | | | | | | | | | | | | | | | | | 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).

* Option parsing: allow aliases in groupsHans Wennborg2013-07-221-6/+4
| | | | | | | | | 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] Add inclusion and exclusion flags to option parsingReid Kleckner2013-07-191-6/+22
| | | | | | | | | | | | | | | | | | | Summary: This allows the clang driver to put MSVC compatible options in the same enumerator space as its normal options but exclude them from normal option parsing. Also changes the standard ParseArgs() method to consider unknown arguments with a leading slash as being inputs rather than flags.

* Revert "[Option] Store arg strings in a set backed by a BumpPtrAllocator"Reid Kleckner2013-07-151-11/+2
| | | | | | | | | This broke clang's crash-report.c test, and I haven't been able to figure it out yet. This reverts commit r186319. llvm-svn: 186329
* [Option] Store arg strings in a set backed by a BumpPtrAllocatorReid Kleckner2013-07-151-2/+11
| | | | | | | | | | | No functionality change. This is preparing to move response file parsing into lib/Option so it can be shared between clang and lld. This change isn't just a micro-optimization. Clang's driver uses a std::set<std::string> to unique arguments while parsing response files, so this matches that. llvm-svn: 186319
* Fix a crash bug in dumping options with groupsReid Kleckner2013-06-261-4/+6
| | | | | | | | Option groups don't have prefixes. Option dumping is basically dead code unless there is something wrong with the option table, so this isn't an important crasher. llvm-svn: 185031
* Merge changes to clang's Driver code into LLVM's Option libraryReid Kleckner2013-06-132-7/+29
| | | | | | | | | | | | This is in preparation for switching the clang driver over to using LLVM's Option library. Richard Smith introduced most of these changes to the clang driver in r167638.
