@ Check whether the section is switched back properly.

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

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