2017-04-07[builtins] Get the builtins tests passing on WindowsReid Kleckner
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. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@299780 91177308-0d34-0410-b5e6-96231b3b80d8

2017-01-11builtins: support building ARM builtins for a HF targetSaleem Abdulrasool
The `-target` impacts the CC for the builtins. HF targets (with either floating point ABI) always use AAPCS VFP for the builtins unless they are AEABI builtins, in which case they use AAPCS. Non-HF targets (with either floating point ABI) always use AAPCS for the builtins and AAPCS for the AEABI builtins. This introduces the thunks necessary to switch CC for the floating point operations. This is not currently enabled, and should be dependent on the target being used to build compiler-rt. However, as a stop-gap, a define can be added for ASFLAGS to get the thunks. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@291677 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@288099 91177308-0d34-0410-b5e6-96231b3b80d8

Provide a supplementary header to ensure that the necessary declarations are present for the build of the C unwinding personality. Note that this is NOT an ABI break. It merely is a compile time failure due to the constants not being present. The constants here are reproduced equivalently. This header should permit building with clang[<3.9] as well as gcc.

2016-10-26[ARM RT] Fix broken clear_cache debug build on ARMRenato Golin
clear_cache is using R7 for the SVC call and that's the frame pointer in GCC, which is only disabled on -O2/3, so Release builds finish, Debug don't. Fixes PR30797. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@285204 91177308-0d34-0410-b5e6-96231b3b80d8
2016-09-27builtins: use thumb-2 if possible on comparesf2Saleem Abdulrasool
This code can be built with thumb-2 like many of the other builtin routines. Enable that here as well. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@282530 91177308-0d34-0410-b5e6-96231b3b80d8
2016-09-07builtins: make sure that flags is setup properly for __clear_cacheSaleem Abdulrasool
On Linux ARM, the syscall will take 3 arguments (start, end, flags). Ensure that we do not pass garbage to the flags, which can cause the cacheflush call to fail, and therefore cause an abort at runtime. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@280877 91177308-0d34-0410-b5e6-96231b3b80d8
2016-09-01[CMake] Add option (defaulted off) to exclude atomic.cChris Bieneman
The atomic builtin source is problematic when cross-compiling builtins because it requires a variable and sometimes large set of system headers. This option allows users to optionally prevent it from being built. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@280416 91177308-0d34-0410-b5e6-96231b3b80d8
