; This test is to make sure that the necessary alignment for thread locals
; gets reflected in the TLS Directory of the generated executable on x86-64.
; aligned_thread_local specifies 'align 64' and so the generated
; exe should reflect that with a value of IMAGE_SCN_ALIGN_64BYTES
; in the Characteristics field of the IMAGE_TLS_DIRECTORY
