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.

Summary: This change adds an arch-specific subdirectory in <ResourceDir>/lib/<OS> to the linker search path. This path also gets added as '-rpath' for native compilation if a runtime is linked in as a shared object. This allows arch-specific libraries to be installed alongside clang.

As is the case on platforms like Mips, X86 and SystemZ, the -fomit-frame-pointer should be enabled by default on PPC when optimizing at -O1 and above. This brings the behaviour of LLVM on PPC in line with GCC. Committing on behalf of Hiroshi Inoue. Differential Revision: https://reviews.llvm.org/D29750 llvm-svn: 296861

This patch moves helper functions that are CPU-specific out of Driver.cpp and to separate implementation files. The new files are named for the architecture, e.g. ARMArch.cpp. The next step after this will be to move OS-specific code, which I expect will include many of the tool implementations, to similarly separate files. Some CPU-specific functions are not being moved just yet. In cases where the only caller is the platform-specific tools, I plan to move them together. An example is Hexagon, where the only caller of the architecture-specific functions are the tools themselves. (I'm happy to revise this choice, it just seems like less churn to me.) This does mean that some functions which were previously static are now exposed through the library header Driver.h.
