1# Testing configuration for Apple's system libc++abi.2#3# This configuration differs from a normal LLVM shared library configuration in4# that we must use DYLD_LIBRARY_PATH to run the tests against the just-built library,5# since Apple's libc++abi has an absolute install_name.6#7# Finally, we also link against an artificial shims library that provides8# the functionality necessary for the upstream libc++abi to be usable in place9# of a system-provided libc++abi. Without that, attempting to replace the system10# libc++abi with DYLD_LIBRARY_PATH would result in missing symbols and other similar11# issues since the upstream libc++abi does not contain all the symbols provided by12# the system library.13 14lit_config.load_config(config, '@CMAKE_CURRENT_BINARY_DIR@/cmake-bridge.cfg')15 16import os, site17site.addsitedir(os.path.join('@LIBCXXABI_LIBCXX_PATH@', 'utils'))18import libcxx.test.params, libcxx.test.config, libcxx.test.dsl19ADDITIONAL_PARAMETERS = [20 libcxx.test.dsl.Parameter(name='apple_system_shims', type=str,21 actions=lambda path: [libcxx.test.dsl.AddSubstitution('%{apple-system-shims}', path)],22 help="""23 Path to a pre-built object file or static archive that contains shims necessary to24 allow replacing the system libc++abi by the just-built one.25 """),26]27 28config.substitutions.append(('%{flags}',29 '-isysroot {}'.format('@CMAKE_OSX_SYSROOT@') if '@CMAKE_OSX_SYSROOT@' else ''30))31config.substitutions.append(('%{compile_flags}',32 '-nostdinc++ -I %{include} -I %{cxx-include} -I %{cxx-target-include} %{maybe-include-libunwind} -D_LIBCPP_ENABLE_CXX17_REMOVED_UNEXPECTED_FUNCTIONS ' +33 '-I %{libcxx}/test/support -I %{libcxx}/src'34))35config.substitutions.append(('%{link_flags}',36 '-nostdlib++ -L %{lib} -lc++ %{apple-system-shims}'37))38config.substitutions.append(('%{exec}',39 '%{executor} --execdir %{temp} --env DYLD_LIBRARY_PATH=%{lib} -- '40))41 42config.stdlib = 'apple-libc++'43 44libcxx.test.config.configure(45 libcxx.test.params.DEFAULT_PARAMETERS + ADDITIONAL_PARAMETERS,46 libcxx.test.features.DEFAULT_FEATURES,47 config,48 lit_config49)50
