I think ".ARM.extab.text" and ".ARM.exidx.text" is redundant, and I
suggest that
"*(.ARM.extab .ARM.extab.text.[0-9a-zA-Z_]*)"
"*(.ARM.exidx .ARM.exidx.text.[0-9a-zA-Z_]*)"
instead.
Mapping between the text sections and exidx sections in .o files
generated by the compilers:
".text" -> ".ARM.exidx"
".text.xx" -> ".ARM.exidx.text.xx"
".ARM.extab.text" and ".ARM.exidx.text" sections will never be
generated by the compilers.
