      8 @ The assembler should switch the section back to the corresponding section
      9 @ after it have emitted the exception handling indices and tables.  In this
     10 @ test case, we are checking whether the section is correct when .section
     11 @ directives is used.

     13 @ In this example, func1 and func2 should be defined in .TEST1 section.
     14 @ It is incorrect if the func2 is in .text, .ARM.extab.TEST1, or
     15 @ .ARM.exidx.TEST1 sections.
