// Older versions of LLVM had a bug where we would accidentally
// truncate the number of epilogue scopes to a uint8_t; make
// sure this doesn't happen.
//
// We expect the llvm-readobj invocation to fail because the
// xdata section is truncated (to reduce the size of the testcase).

// CHECK: EpilogueScopes: 256
