* [Clang] Migrate llvm::make_unique to std::make_uniqueJonas Devlieghere2019-08-141-2/+2
| | | | | | | | | | Now that we've moved to C++14, we no longer need the llvm::make_unique implementation from STLExtras.h. This patch is a mechanical replacement of (hopefully) all the llvm::make_unique instances across the monorepo. Differential revision: https://reviews.llvm.org/D66259 llvm-svn: 368942

* 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
* Lift VFS from clang to llvm (NFC)Jonas Devlieghere2018-10-101-1/+1
| | | | | | | | | | | | | | | | | | | This patch moves the virtual file system form clang to llvm so it can be used by more projects. Concretely the patch: - Moves VirtualFileSystem.{h|cpp} from clang/Basic to llvm/Support. - Moves the corresponding unit test from clang to llvm. - Moves the vfs namespace from clang::vfs to llvm::vfs. - Formats the lines affected by this change, mostly this is the result of the added llvm namespace.

* [mips] Explicitly specify the linker emulation for MIPS on FreeBSD.John Baldwin2018-06-271-6/+29
| | | | | | | | | | | | | | FreeBSD's mips64 builds O32 binaries for /usr/lib32 by default and thus needs to be able to link O32 binaries which requires an explicit linker emulation. Go ahead and list all the linker emulation variants for MIPS so that any supported MIPS ABI binary can be linked by any linker supporting MIPS.

| | | | | | | | | | | | | | | | | | | Summary: This change fixes http://llvm.org/PR36985 to define a single place in CommonArgs.{h,cpp} where XRay runtime flags and link-time dependencies are processed for all toolchains that support XRay instrumentation. This is a refactoring of the same functionality spread across multiple toolchain definitions.

* Introduce -nostdlib++ flag to disable linking the C++ standard library.Nico Weber2017-07-251-1/+2
| | | | | | | | | | | | | | | Projects that want to statically link their own C++ standard library currently need to pass -nostdlib or -nodefaultlibs, which also disables linking of the builtins library, -lm, and so on. Alternatively, they could use `clang` instead of `clang++`, but that already disables implicit addition of -lm on some toolchains. Add a dedicated flag -nostdlib++ that disables just linking of libc++ / libstdc++. This is analogous to -nostdinc++. https://reviews.llvm.org/D35780 llvm-svn: 308997
* [Driver] Consolidate tools and toolchains by target platform. (NFC)David L. Jones2017-03-081-0/+395
Summary: (This is a move-only refactoring patch. There are no functionality changes.) This patch splits apart the Clang driver's tool and toolchain implementation files. Each target platform toolchain is moved to its own file, along with the closest-related tools. Each target platform toolchain has separate headers and implementation files, so the hierarchy of classes is unchanged. There are some remaining shared free functions, mostly from Tools.cpp. Several of these move to their own architecture-specific files, similar to r296056. Some of them are only used by a single target platform; since the tools and toolchains are now together, some helpers now live in a platform-specific file. The balance are helpers related to manipulating argument lists, so they are now in a new file pair, CommonArgs.h and .cpp. I've tried to cluster the code logically, which is fairly straightforward for most of the target platforms and shared architectures. I think I've made reasonable choices for these, as well as the various shared helpers; but of course, I'm happy to hear feedback in the review. There are some particular things I don't like about this patch, but haven't been able to find a better overall solution. The first is the proliferation of files: there are several files that are tiny because the toolchain is not very different from its base (usually the Gnu tools/toolchain). I think this is mostly a reflection of the true complexity, though, so it may not be "fixable" in any reasonable sense. The second thing I don't like are the includes like "../Something.h". I've avoided this largely by clustering into the current file structure. However, a few of these includes remain, and in those cases it doesn't make sense to me to sink an existing file any deeper.
