Author: arichardson Date: Fri Feb 23 07:19:48 2018 New Revision: 325914 URL: http://llvm.org/viewvc/llvm-project?rev=325914&view=rev Log: Allow passing additional compiler/linker flags for the tests
Summary: These flags can be specified using the CMake variables LIBCXX_TEST_LINKER_FLAGS and LIBCXX_TEST_COMPILER_FLAGS. When building the tests for CHERI I need to pass additional flags (such as -mabi=n64 or -mabi=purecap) to the compiler for our test configurations Reviewers: EricWF Reviewed By: EricWF Subscribers: christof, mgorny, cfe-commits Differential Revision: https://reviews.llvm.org/D42139 Modified: libcxx/trunk/test/CMakeLists.txt libcxx/trunk/test/lit.site.cfg.in libcxx/trunk/utils/libcxx/test/config.py Modified: libcxx/trunk/test/CMakeLists.txt URL: http://llvm.org/viewvc/llvm-project/libcxx/trunk/test/CMakeLists.txt?rev=325914&r1=325913&r2=325914&view=diff ============================================================================== --- libcxx/trunk/test/CMakeLists.txt (original) +++ libcxx/trunk/test/CMakeLists.txt Fri Feb 23 07:19:48 2018 @@ -9,6 +9,11 @@ endmacro() set(LIBCXX_LIT_VARIANT "libcxx" CACHE STRING "Configuration variant to use for LIT.") +set(LIBCXX_TEST_LINKER_FLAGS "" CACHE STRING + "Additonal linker flags to pass when compiling the tests") +set(LIBCXX_TEST_COMPILER_FLAGS "" CACHE STRING + "Additonal linker flags to pass when compiling the tests") + # The tests shouldn't link to any ABI library when it has been linked into # libc++ statically or via a linker script. if (LIBCXX_ENABLE_STATIC_ABI_LIBRARY OR LIBCXX_ENABLE_ABI_LINKER_SCRIPT) Modified: libcxx/trunk/test/lit.site.cfg.in URL: http://llvm.org/viewvc/llvm-project/libcxx/trunk/test/lit.site.cfg.in?rev=325914&r1=325913&r2=325914&view=diff ============================================================================== --- libcxx/trunk/test/lit.site.cfg.in (original) +++ libcxx/trunk/test/lit.site.cfg.in Fri Feb 23 07:19:48 2018 @@ -22,6 +22,9 @@ config.sysroot = "@LIBC config.gcc_toolchain = "@LIBCXX_GCC_TOOLCHAIN@" config.generate_coverage = "@LIBCXX_GENERATE_COVERAGE@" config.target_info = "@LIBCXX_TARGET_INFO@" +config.test_linker_flags = "@LIBCXX_TEST_LINKER_FLAGS@" +config.test_compiler_flags = "@LIBCXX_TEST_COMPILER_FLAGS@" + config.executor = "@LIBCXX_EXECUTOR@" config.llvm_unwinder = "@LIBCXXABI_USE_LLVM_UNWINDER@" config.compiler_rt = "@LIBCXX_USE_COMPILER_RT@" Modified: libcxx/trunk/utils/libcxx/test/config.py URL: http://llvm.org/viewvc/llvm-project/libcxx/trunk/utils/libcxx/test/config.py?rev=325914&r1=325913&r2=325914&view=diff ============================================================================== --- libcxx/trunk/utils/libcxx/test/config.py (original) +++ libcxx/trunk/utils/libcxx/test/config.py Fri Feb 23 07:19:48 2018 @@ -510,6 +510,9 @@ class Configuration(object): # and so that those tests don't have to be changed to tolerate # this insanity. self.cxx.compile_flags += ['-DNOMINMAX'] + additional_flags = self.get_lit_conf('test_compiler_flags') + if additional_flags: + self.cxx.compile_flags += shlex.split(additional_flags) def configure_default_compile_flags(self): # Try and get the std version from the command line.
