// Test that basic ELF static initializers work. The main function in this
// test returns the value of 'x', which is initially 1 in the data section,
// and reset to 0 if the _static_init function is run. If the static initializer
// does not run then main will return 1, causing the test to be treated as a
// failure.
//
// RUN: %clang -c -o %t %s
// RUN: %llvm_jitlink %t
