// This test is copied from clang/test/CodeGen/dso-local-executable.c with
// unsupported targets, thread_local variables, and function checks removed.
// These are here so we find this test when grepping for missing features.
// cir::MissingFeatures::opGlobalThreadLocal()

// a difference from classic codege in the STATIC checks.

/// dso_local on most global objects.
