Is there any specific reason why the clang_rt.builtins-${arch} library is disabled for windows builds?
if (NOT WIN32)
foreach(arch x86_64 i386 arm)
if(CAN_TARGET_${arch})
set_source_files_properties(${${arch}_SOURCES} PROPERTIES
LANGUAGE C)
add_compiler_rt_runtime(clang_rt.builtins-${arch} ${arch} STATIC
SOURCES ${${arch}_SOURCES}
CFLAGS “-std=c99”)
add_dependencies(builtins clang_rt.builtins-${arch})
endif()
endforeach()
endif()
