// 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.
