[CMake] Support platform building builtins without a full toolchain Summary: This patch adds support for building lib/builtins without a fully functioning toolchain. It allows you to bootstrap a cross-compiler, which previously couldn't be done with CMake. This patch contains the following specific changes: * Split builtin-specific code out of config-ix.cmake into builtin-config-ix.cmake * Split some common CMake functionality needed by both builtins and sanitizers into base-config-ix.cmake * Made lib/builtins/CMakeLists.txt able to be a top-level CMake configuration I have tested this on Darwin targeting embedded Darwin, and on FreeBSD x86_64 targeting FreeBSD AArch64. This patch depends on http://reviews.llvm.org/D19692, and is the last part of http://reviews.llvm.org/D16653.

Add generic __bswap[ds]i2 implementations Summary: In FreeBSD we needed to add generic implementations for `__bswapdi2` and `__bswapsi2`, since gcc 6.x for mips is emitting calls to these. See: https://reviews.freebsd.org/D10838 and https://reviews.freebsd.org/rS318601 The actual mips code generated for these generic C versions is pretty OK, as can be seen in the (FreeBSD) review. I checked over gcc sources, and it seems that it can emit these calls on more architectures, so maybe it's best to simply always add them to the compiler-rt builtins library.

I added an explicit cast; it shouldn't affect other types. - we can't pass __fp16, so src_t and src_rep_t are the same. - the gnu_*_ieee symbols are simply duplicated definitions, as aliases are problematic on mach-o (where only weak aliases are supported; that's not what we want).

[builtins] Get the builtins tests passing on Windows Many things were broken: - We stopped building most builtins on Windows in r261432 for reasons that are not at all clear to me. This essentially reverts that patch. - Fix %librt to expand to clang_rt.builtins-$arch.lib on Windows instead of libclang_rt.builtins-$arch.a. - Fix memory protection tests (trampoline, enable executable, clear cache) on Windows. One issue was that the MSVC incremental linker generates ILT thunks for functions with external linkage, so memcpying the functions into the executable stack buffer wasn't working. You can't memcpy an RIP-relative jump without fixing up the offset. - Disable tests that rely on C99 complex library functions when using the MSVC CRT, which isn't compatible with clang's C99 _Complex. In theory, these could all be separate patches, but it would not green the tests, so let's try for it all at once. Hopefully this fixes the clang-x64-ninja-win7 bot. llvm-svn: 299780

[compiler-rt] Add AArch64 to CMake configuration and several missing builtins Summary: Currently CMake doesn't build builtins for AArch64 and if one does this anyway it's likely that at least `__multc3`, `__floatditf` and `__floatunditf` will be missing. There is actually more builtins to add, but these come from different libc implementations, thus providing them makes compiler-rt for AArch64 good enough at least for basic usage. Builtins implementation were originally taken from FreeBSD project: * [[ https://reviews.freebsd.org/D2173 | __multc3 ]] * [[ https://reviews.freebsd.org/D2174 | __floatditf and __floatunditf ]] Until they have been tested to find mistakes in `__float*` functions. `__floatditf` was based on `__floatsitf`, which had the same mistakes (fixed it in r243746). Version of the builtins in this patch are fixed and complemented with basic tests. Additionally they were tested via GCC's torture (this is what revealed these issues). P.S. Ed (author of FreeBSD patches) asked for feedback on the list some time ago (here [[ http://lists.cs.uiuc.edu/pipermail/llvmdev/2015-March/084064.html | here ]]) and got no response, but it seems to be worth adding these builtins as is and extracting common part later.

[compiler-rt] Add AArch64 to CMake configuration and several missing builtins Summary: Currently CMake doesn't build builtins for AArch64 and if one does this anyway it's likely that at least `__multc3`, `__floatditf` and `__floatunditf` will be missing. There is actually more builtins to add, but these come from different libc implementations, thus providing them makes compiler-rt for AArch64 good enough at least for basic usage. Builtins implementation were originally taken from FreeBSD project: * [[ https://reviews.freebsd.org/D2173 | __multc3 ]] * [[ https://reviews.freebsd.org/D2174 | __floatditf and __floatunditf ]] Until they have been tested to find mistakes in `__float*` functions. `__floatditf` was based on `__floatsitf`, which had the same mistakes (fixed it in r243746).

build: create two versions of ARM builtins This adds a new name for ARM32 (armhf). We now force that the default build for ARM32 (arm) to be soft-float ABI. This has a corresponding clang change to look for these names based on the floating point ABI. The functions are built identically (the functions are marked as AAPCS, so the calling convention does not change, as per the RTABI specification), however, the object file contains attributes indicating the build configuration which the linker will ensure are not mix and matched. We now built the appropriate named archive so that we can link properly. llvm-svn: 248648

builtins: switch to c11 from c99 This fixes an incorrect standard usage of GNU99 when the compiler check was for the ISO standard C99. Furthermore, bump the dependency up to C11. The motivation for this change is ARM EHABI compatibility with clang 3.8. We rely on a type definition redefinition which causes an error with -Werror builds. This is problematic for FreeBSD builds. Switching to C11 allows the compatibility without the unnecessary pedantic warning. The alternative would be to clutter the support header with a `pragma clang diagnostic ignore`. GCC 4.8+ and the supported clang revisions along with MSVC support enough of C11 to allow building the builtins in C11 mode. No functional change intended. llvm-svn: 288099

The runtime built for i686 will be identical to the one built for i386. 2. Supporting both -i386 and -i686 suffixes causes unnecessary confusion on the clang end which has to expect either of them. 3. The checks are based on wrong assumption that __i686__ is defined for all newer x86 CPUs. In fact, it is only declared when -march=i686 is explicitly used. It is not available when a more specific (or newer) -march is used. Curious enough, if CFLAGS contain -march=i686, the runtime will be built both for i386 and i686. For any other value, only i386 variant will be built. Differential Revision: https://reviews.llvm.org/D26764 llvm-svn: 311924

This would result in multiple definitions of those symbols. The linker is free to select either of the two. Most of the time, this shouldn't be too terrible as the forward iteration should catch the architecture version due to the ordering. Rather than relying on the linker and build infrastructure ordering things in a specific manner, only provide the architecture version when available. This reduces the size of compiler-rt, simplifies inspection of the library implementations, and guarantees that the desired version is selected at a slightly complex build system. llvm-svn: 214040

builtins: ensure that VISIBILITY_HIDDEN is defined properly The CMake build system had missed this macro as part of the build of the builtins. This would result in the builtins exporting symbols which are implemented in assembly with global visibility. Ensure that the assembly optimized routines are given the same visibility as the C routines. llvm-svn: 285477

[CMake] merge add_compiler_rt_runtime and add_compiler_rt_darwin_runtime into a single function Summary: This refactoring moves much of the Apple-specific behavior into a function in AddCompilerRT. The next cleanup patch will remove more of the if(APPLE) checks in the outlying CMakeLists. This patch adds a bunch of new functionality to add_compiler_rt_runtime so that the target names don't need to be reconstructed outside the call. It also updates some of the call sites to exercise the new functionality, but does not update all uses fully. Subsequent patches will further update call sites and move to using the new features.

builtins: avoid multiple definitions of symbols The architecture specific implementation of routines would be built and included along with the generic implementation. This would result in multiple definitions of those symbols. The linker is free to select either of the two. Most of the time, this shouldn't be too terrible as the forward iteration should catch the architecture version due to the ordering. Rather than relying on the linker and build infrastructure ordering things in a specific manner, only provide the architecture version when available.
