| 6 | @ The assembler should switch the section back to the corresponding section |
| 7 | @ after it have emitted the exception handling indices and tables. In this |
| 8 | @ test case, we are checking whether the section is correct when .section |
| 9 | @ directives is used. |
| 10 | |
| 11 | @ In this example, func1 and func2 should be defined in .TEST1 section. |
| 12 | @ It is incorrect if the func2 is in .text, .ARM.extab.TEST1, or |
| 13 | @ .ARM.exidx.TEST1 sections. |
