2017-09-01[cmake] Work around -Wunused-driver-argument warningsVedant Kumar
Fix the Darwin logic so that -msse3 is only used on macOS, and -fomit-frame-pointer is not used on armv7/armv7k/armv7s. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@312390 91177308-0d34-0410-b5e6-96231b3b80d8
2017-08-30[builtins] Prevent duplicate definitions for overridden functionsFrancis Ricci
Summary: Some architecture-specific function overrides (for example, i386/ashrdi3.S) duplicate generic functions (in that case, ashrdi3.c). Prevent duplicate definitions by filtering out the generic files before compiling.

2017-07-07[cmake] Cache results of find_darwin_sdk_dirKuba Mracek
This improves find_darwin_sdk_dir to cache the results of executing xcodebuild to find the SDK. Should significantly reduce the CMake re-configure time.

2017-07-06[cmake] Add an option to prefer public SDK in find_darwin_sdk_dirKuba Mracek
Adds a CMake option DARWIN_PREFER_PUBLIC_SDK, off by default. When on, this prefers to use the public SDK, even when an internal one is present. With this, it's easy to emulate a build that the public buildbots are doing.

2017-03-21[compiler-rt] respect CMAKE_EXE_LINKER_FLAGS in compiler and library testsBob Haarman
Summary: check_cxx_compiler_flag and check_library_exists could fail because they ignored CMAKE_EXE_LINKER_FLAGS and therefore would always fail to produce executables. Cmake policy CMP0056 fixes this, but was explicitly set to OLD in our CMakeLists because it caused problems with test_target_arch. This change sets the policy to NEW to fix the problem with the compiler and library tests, and temporarily clears CMAKE_EXE_LINKER_FLAGS inside test_target_arch to emulate the old behavior there. This allows, for example, LTO builds that require lld to succeed.

2017-01-10Make cmake link flag naming consistentFrancis Ricci
Summary: The build system was inconsistent in its naming conventions for link flags. This patch changes all uses of LINKFLAGS to LINK_FLAGS, for consistency with cmake's LINK_FLAGS property. This patch should make it easier to search the source code for uses of link flags, as well as providing the benefit of improved style and consistency.

2016-08-19[CMake] Support building on OS X without Xcode installationChris Bieneman
This should resolve PR23162. This patch has two parts. First we need to check the error code from xcodebuild when querying for SDKs, second if the OS X SDK is not discovered, we ensure that /usr/include exists and use / as the OS X sysroot. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@279336 91177308-0d34-0410-b5e6-96231b3b80d8

2016-05-03[CMake] NFC. Add support for testing the compiler without testing the linkerChris Bieneman
Summary: One of the big limitations we have in the compiler-rt build system today is that we cannot bootstrap building the builtins because you need a fully functional toolchain to pass CMake's tests. This change adds support for compile only tests. It is NFC because nothing is using the compile-only tests yet. I believe this is the last separable part of D16653.

For OS X builds of compiler-rt, we run `darwin_test_archs` to determine which architectures can the toolchain target.
