* Fix PR17239 by changing the semantics of the RemainingArgsClass Option kindReid Kleckner2014-08-221-3/+3
| | | | | | | | | | | | | | | | | | | | | | | 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
* Revert "[Support] Promote cl::StringSaver to a separate utility"Sean Silva2014-08-151-2/+9
| | | | | | | | | This reverts commit r215784 / 3f8a26f6fe16cc76c98ab21db2c600bd7defbbaa. LLD has 3 StringSaver's, one of which takes a lock when saving the string... Need to investigate more closely. llvm-svn: 215790
* [Support] Promote cl::StringSaver to a separate utilitySean Silva2014-08-151-9/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This class is generally useful. In breaking it out, the primary change is that it has been made non-virtual. It seems like being abstract led to there being 3 different (2 in llvm + 1 in clang) concrete implementations which disagreed about the ownership of the saved strings (see the manual call to free() in the unittest StrDupSaver; yes this is different from the CommandLine.cpp StrDupSaver which owns the stored strings; which is different from Clang's StringSetSaver which just holds a reference to a std::set<std::string> which owns the strings). I've identified 2 other places in the codebase that are open-coding this pattern: memcpy(Alloc.Allocate<char>(strlen(S)+1), S, strlen(S)+1) I'll be switching them over. They are * llvm::sys::Process::GetArgumentVector * The StringAllocator member of YAMLIO's Input class This also will allow simplifying Clang's driver.cpp quite a bit. Let me know if there are any other places that could benefit from StringSaver. I'm also thinking of adding a saveStringRef member for getting a stable StringRef. llvm-svn: 215784
* Support: Fix option handling when using cl::Required with aliasoptJustin Bogner2014-07-141-0/+19
| | | | | | | | | | | | | | | | Until now, attempting to create an alias of a required option would complain if the user supplied the alias, because the required option didn't have a value. Similarly, if you said the alias was required, then using the base option would complain that the alias wasn't supplied. Lastly, if you put required on both, *neither* option would work. By changning alias to overload addOccurrence and setting cl::Required on the original option, we can get this to behave in a more useful way. I've also added a test and updated a user that was getting this wrong. llvm-svn: 212986

* [Support] Beef up and expose the response file parsing in llvm::clReid Kleckner2013-07-181-0/+24
| | | | | | | | | | | | | | | | | | | The plan is to use it for clang and lld. Major behavior changes: - We can now parse UTF-16 files that have a byte order mark. - PR16209: Don't drop backslashes on the floor if they don't escape anything. The actual parsing loop was based on code from Clang's driver.cpp, although it's been rewritten to track its state with control flow rather than state variables.
