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

This fixes a long-standing TODO by implementing a compiler check for supporting the _Atomic keyword.

2016-07-25Revert "Enable cross-compilation across architectures on android"Chris Bieneman
This reverts commit r276333. As I commented in the review (https://reviews.llvm.org/D22415), this change isn't needed because CMAKE_C_FLAGS is implicitly added by CMake to the command line for all C source files. With this patch enabled CMAKE_C_FLAGS is duplicated on all C sources, and applied to ASM sources, which is not ideal. I sent an email about this to llvm-commits on the commit thread. I suspect the problem the patch author was actually seeing is that CMAKE_C_FLAGS isn't applied to ASM files, and the builtins library has quite a few of those. The correct solution there is to specify CMAKE_ASM_FLAGS with whatever flags need to be passed to the compiler when compiling ASM files. If there are other problems with flag propagation, please let me know. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@276683 91177308-0d34-0410-b5e6-96231b3b80d8

2016-06-22builtins: tag with noexecstackSaleem Abdulrasool
These routines do not require executable stacks. However, by default ELFish linkers may assume an executable stack on GNUish environments (and some non-GNU ones too!). The GNU extension to add a note to indicate a non-executable stack is honoured by these environments to mark the stack as non-executable (the compiler normally emits this directive on appropriate targets whenever possible). This allows normal builds from getting executable stacks due to linking to the compiler rt builtins. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@273500 91177308-0d34-0410-b5e6-96231b3b80d8

2016-05-09[CMake] Support platform building builtins without a full toolchainChris Bieneman
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.
