Hi Aaron!


I have seen on SVN a last version. Yes! It supports now ELF for X86,
perfect! But debug information ( .debug - sections) not implemented. I am
looking for a possibility to use a LLVM with a debugger GDB. And GDB works
with DWARF debug information. 

Will be continue a work with ELF-Writer for support of a debug? Or is there
any other ideas for debug? 

I will add an ELF-Writer to my project (xPEC - processor from chip NetX)!


Sank you!
