build: Add ModuleName per-subdir variable as a way to organize the different sets of functions/objects into high level groups. Currently we have "builtins" (the main compiler-rt code), "profile", and "asan". - Use this to define CommonFunctions and ArchFunctions to only reference the builtins functions. llvm-svn: 145674 2011-12-02 10:42:07 +08:00			`ModuleName := builtins`

MachO: add dummy armv6m architecture directory so clang_macho_embedded builds things. Without some mention of armv6m in a subdirectory of builtins, the make code doesn't even know that armv6m exists and is something it should be looking for in the platform-specific Makefiles. This means that none of the functions listed actually get built and we end up with an almost entirely empty libclang_rt.a for armv6m. Unfortunately, the assembly code in the usual arm directory has no hope of running on armv6m, which only supports Thumb-1 (not even ARM mode), so adding it there won't work. Realistically, we probably will want to put any optimised versions in a separate directory, so creating it now is harmless. rdar://problem/17613576 llvm-svn: 212696 2014-07-10 18:06:42 +08:00			`SubDirs += i386 ppc x86_64 arm armv6m`

AArch64: add support for ARM64 iOS versions of compiler-rt. Just a dummy directory and a few sane choices in the Darwin SDK. rdar://problem/18575597 llvm-svn: 219323 2014-10-09 01:28:37 +08:00			`# Add ARM64 dir.`
