; Test section group of the function with linkonce_odr

; The instantiation of C++ function template will come with linkonce_odr,
; which indicates that the linker can remove the duplicated instantiation.
; However, to make this feature work, we have to group the section properly.
; .text, .ARM.extab, and .ARM.exidx should be grouped together.
