llvm dev - Mar 2018 - [cfe-dev] [GSOC 2018] Information gathering

Hi Eric,

As you are pointed to be the confirmed mentor for the "Command line 
replacements for GNU Binutils" GSOC 2018 subject, I permit myself to add 
you to this thread !


If you have a few minutes to answer my questions, that'd really great 🙂

I just replied with this in another thread:

"It's currently still available. The basic idea is that we'd be
working on
getting each of the llvm tools or libraries with a front end that is
command line compatible with the GNU binutils counterpart to serve as a
replacement. Whether or not we made them output compatible is something
else, but we'll probably want to have a couple different modes there from:

a) The compatible tool,
b) The tool we all want.

A and B could be the same, but then again, they might not. The low bar for
the SoC project is going to be A."

And in priority order I'd probably want to finish off objcopy support (see
the recent thread on llvm-dev) and objdump/readobj/readelf and then go from
there.

Thoughts?

I saw the thread you are talking about. So basically, the idea would be 
to do the correct calls for either COFF subset of functions of ELF ones 
wether we have a COFF or ELF file as an input.
Am I right ?

I am really interested in doing a proposal for this subject. What do you 
expect to be in it ? I was actually thinking of something like exposing 
the things I've done in LLVM/CLang, the schedule for the 3 months (but 
for this, I need to talk with you about the high priority tools, as I'm 
not sure it is possible to do all the frontend tools in such amount of 
time)..

Anyway, I am really happy that you answered my email. Hope to hear from 
you soon !
