@ Check the .group section for the function in comdat section.
@ In C++, the instantiation of the template will come with linkonce (or
@ linkonce_odr) linkage, so that the linker can remove the duplicated
@ instantiation. When the exception handling is enabled on those function,
@ we have to group the corresponding .ARM.extab and .ARM.exidx with the
@ text section together.
@
@ This test case will check the content of .group section. The section index
@ of the grouped sections should be recorded in .group section.
