* Let unaliased Args track which Alias they were created from, and use that in ↵Nico Weber2019-07-091-42/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Arg::getAsString() for diagnostics With this, `clang-cl /source-charset:utf-16 test.cc` now prints `invalid value 'utf-16' in '/source-charset:utf-16'` instead of `invalid value 'utf-16' in '-finput-charset=utf-16'` before, and several other clang-cl flags produce much less confusing output as well. Fixes PR29106. Since an arg and its alias can have different arg types (joined vs not) and different values (because of AliasArgs<>), I chose to give the Alias its own Arg object. For convenience, I just store the alias directly in the unaliased arg – there aren't many arg objects at runtime, so that seems ok. Finally, I changed Arg::getAsString() to use the alias's representation if it's present – that function was already documented as being the suitable function for diagnostics, and most callers already used it for diagnostics. Implementation-wise, Arg::accept() previously used to parse things as the unaliased option. The core of that switch is now extracted into a new function acceptInternal() which parses as the _aliased_ option, and the previously-intermingled unaliasing is now done as an explicit step afterwards. (This also changes one place in lld that didn't use getAsString() for diagnostics, so that that one place now also prints the flag as the user wrote it, not as it looks after it went through unaliasing.)

* Make joined instances of JoinedOrSeparate flags point to the unaliased args, ↵Nico Weber2019-07-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | like all other arg types do This fixes an 8-year-old regression. r105763 made it so that aliases always refer to the unaliased option – but it missed the "joined" branch of JoinedOrSeparate flags. (r162231 then made the Args classes non-virtual, and r169344 moved them from clang to llvm.) Back then, there was no JoinedOrSeparate flag that was an alias, so it wasn't observable. Now /U in CLCompatOptions is a JoinedOrSeparate alias in clang, and warn_slash_u_filename incorrectly used the aliased arg id (using the unaliased one isn't really a regression since that warning checks if the undefined macro contains slash or backslash and only then emits the warning – and no valid use will pass "-Ufoo/bar" or similar). Also, lld has many JoinedOrSeparate aliases, and due to this bug it had to explicitly call `getUnaliasedOption()` in a bunch of places, even though that shouldn't be necessary by design. After this fix in Option, these calls really don't have an effect any more, so remove them. No intended behavior change. (I accidentally fixed this bug while working on PR29106 but then wondered why the warn_slash_u_filename broke. When I figured it out, I thought it would make sense to land this in a separate commit.)

* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. 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
* IWYU for llvm-config.h in llvm, additions.Nico Weber2018-04-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | See r331124 for how I made a list of files missing the include. I then ran this Python script: for f in open('filelist.txt'): f = f.strip() fl = open(f).readlines() found = False for i in xrange(len(fl)): p = '#include "llvm/' if not fl[i].startswith(p): continue if fl[i][len(p):] > 'Config': fl.insert(i, '#include "llvm/Config/llvm-config.h"\n') found = True break if not found: print 'not found', f else: open(f, 'w').write(''.join(fl)) and then looked through everything with `svn diff | diffstat -l | xargs -n 1000 gvim -p` and tried to fix include ordering and whatnot. No intended behavior change. llvm-svn: 331184

* [dump] Remove NDEBUG from test to enable dump methods [NFC]Don Hinton2017-10-121-1/+1
| | | | | | | | | | | | | | | Summary: Add LLVM_FORCE_ENABLE_DUMP cmake option, and use it along with LLVM_ENABLE_ASSERTIONS to set LLVM_ENABLE_DUMP. Remove NDEBUG and only use LLVM_ENABLE_DUMP to enable dump methods. Move definition of LLVM_ENABLE_DUMP from config.h to llvm-config.h so it'll be picked up by public headers.

* Fix PR17239 by changing the semantics of the RemainingArgsClass Option kindReid Kleckner2014-08-221-4/+8
| | | | | | | | | | | | | | | | | | | | | | | This patch contains the LLVM side of the fix of PR17239. This bug that happens because the /link (clang-cl.exe argument) is marked as "consume all remaining arguments". However, when inside a response file, /link should only consume all remaining arguments inside the response file where it is located, not the entire command line after expansion. My patch will change the semantics of the RemainingArgsClass kind to always consume only until the end of the response file when the option originally came from a response file. There are only two options in this class: dash dash (--) and /link. Reviewed By: rnk Differential Revision: http://reviews.llvm.org/D4899 Patch by Rafael Auler! llvm-svn: 216280

* Options: Add new option kind that consumes remaining argumentsHans Wennborg2013-08-131-0/+11
| | | | | | | | | | | | | | | | 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: 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).
