I am not familiar enough with ARM toolchain to say one way or another.
In terms of what ELF libraries can contain, sure it should be possible.
The unwind info is in .eh_frame{,_hdr} sections on other platforms. But
I had understood from other ARM-related mails on this list that some other
(.debug_frame?) section was used on ARM instead. I don't know if that is
universal, or specific to one toolchain (IIRC that was uclibc).

Lassi
