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.

2017-01-30[sanitizer] Re-enable -fno-function-sections for powerpc64leKostya Kortchinsky
Summary: For a reason that hasn't been investigated for lack of powerpc knowledge and hardware, -fno-function-sections is required for the Sanitizers to work properly on powerpc64le. Without, the function-sections-are-bad test fails on that architecture (and that architecture only). This patch re-enables the flag in the powerpc64le cflags. I have to admit I am not entirely sure if my way is the proper way to do this, so if anyone has a better way, I'll be happy to oblige.

2017-01-26[sanitizer] Remove -fno-function-sections from SANITIZER_COMMON_CFLAGSKostya Kortchinsky
Summary: -fno-function-sections was added as a default Sanitizer common cflag with https://reviews.llvm.org/rL200683, the reasoning behind was that things would break if linked with --gc-sections. This appears to not be necessary anymore, as tests pass without, including function-sections-are-bad.cc. There is a large benefit to having function-sections when dealing with static libraries in terms of size and dependencies that go away with --gc-sections.
