I am trying to emit dwarf debug information for my target. By using
objdump or llvm-objdump
with `--dwarf=frames`, I can only see CIE (Common Information Entry)
but not FDE (Frame
Description Entry). Right now, my target LLVM backend only emit
assembly, and let binutils
do the rest. I don't know where the problem is, is there something
wrong in my target LLVM
backend or in the binutils?
Please point me where should I look into, I will be very
appreciated. Thanks.

What .cfi_* directives do you see in your assembly?
If gcc supports your target, how does its behavior compare?
