Yes... and it's the kind of assembler we need to port Linux.

I've been using several versions of masm, tasm, as86, gas, and nasm.
So what?
No I'm not going to write an ELF loader in VHDL.
I'll write a linker in C :)

Nothing special. But it's a pretty big piece of work to build all the
ELF structures manually.
