      7 // Get the list of ASan wrappers exported by the main module RTL:
      8 // RUN: dumpbin /EXPORTS %t | grep -o "__asan_wrap[^ ]*" | grep -v @ | sort | uniq > %t.exported_wrappers
      9 // FIXME: we should really check the other __asan exports too.
     10 // RUN: dumpbin /EXPORTS %t | grep -o "__sanitizer_[^ ]*" | grep -v @ | sort | uniq >> %t.exported_wrappers
     11 //
     12 // Get the list of ASan wrappers imported by the DLL RTL:
     13 // [BEWARE: be really careful with the sed commands, as this test can be run
     14 //  from different environemnts with different shells and seds]
     15 // RUN: grep INTERCEPT_LIBRARY_FUNCTION %p/../../../../lib/asan/asan_win_dll_thunk.cc | grep -v define | sed -e s/.*(/__asan_wrap_/ | sed -e s/).*// | sort | uniq > %t.dll_imports
