      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.

     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.
