   1 // Test that basic COFF static initializers work. The main function in this
   2 // test returns the expression a + b + c + 1. a is initialzed as -1 and c is
   3 // initialized as -2 by static initializers. b is initialized as 2 by constant
   4 // value. The test will succeeds only if static initializers are ran successfully.
