// clang-cl cannot generate S_CONSTANT records, but we need to test that we can
// handle them for compatibility with MSVC, which does emit them.  This test
// case was generated by compiling this file with MSVC and copying the bytes
// that they emit for S_CONSTANT records.  Then we compile the same code with
// clang to get a .s file, and replace all S_LDATA32 records with the bytes from
// the S_CONSTANT records.  This way we end up with a .s file that contains
// symbol records that clang-cl won't generate.
