Thanks for working on this!

Typo.

Don't suppose I could persuade you to give these names instead of
numbers?  ".cfi_sections .eh_frame" and a hypothetical
".cfi_sections .debug_frame,.ARM.extab"?

[The CFI directives are either sufficient, or very nearly so, for the
ARM unwind tables - as long as you don't try to do certain fancy
things with them.  At least one other toolchain uses the same
directives for the tables and for .debug_frame.]
