RE: gdb supports dwarf2 which is generated by ADS compiler?

["Jang, Jaewoo" <jaewoo dot jang at aromasoft dot com>]

I am concerned for not reading my words because they are below replys.

I wrote as

 As Trace32 debugger can also read the elf file which is 
 generated by ADS,
 I think the elf file is not far from DWARF spec.
 
 But ADS debugger(adw) can not read gdb's elf file.
 I am curious that gdb can support DWARF spec correctly.

 Anyway, I just have one question.
 does gdb support this particular output from ADS?
 (I don't think DWARF generated by ADS is not correct.)
