@ Check the combination of .section, .fnstart, and .fnend directives.

@ For the functions in .text section, the exception handling index (EXIDX)
@ should be generated in .ARM.exidx, and the exception handling table (EXTAB)
@ should be generated in .ARM.extab.

@ For the functions in custom section specified by .section directives,
@ the EXIDX should be generated in ".ARM.exidx[[SECTION_NAME]]", and the EXTAB
@ should be generated in ".ARM.extab[[SECTION_NAME]]".
