6@ In C++, the instantiation of the template will come with linkonce (or
7@ linkonce_odr) linkage, so that the linker can remove the duplicated
8@ instantiation.  When the exception handling is enabled on those function,
9@ we have to group the corresponding .ARM.extab and .ARM.exidx with the
10@ text section together.
11@
12@ This test case will check the content of .group section.  The section index
13@ of the grouped sections should be recorded in .group section.
