.eh_frame

[Masao Uebayashi <uebayasi%gmail.com@localhost>]

Do I understand this correctly?

o .eh_frame is GNU extension debug info to unwind stack [1]
o .eh_frame is generated by GCC/LLVM [2]
o Some code under src/sys/ reference it, but not finished & hooked to any
  kernel functionality (ddb(4)?)
o .eh_frame in kernel is not used yet, and safely removed from /netbsd
