llvm dev - Aug 2018 - [GSoC] Command line replacements for GNU Binutils

Hi all !

During this GSoC, I've worked on improving the llvm binutils suite. I've
wrote a final [1]report for those of you who would be interested.

Regards,

Thanks for everything, Paul! I hope it was a great GSoC for you. All your
patches have been very useful :)

You mentioned FreeBSD switching to llvm-objdump at the end. I wonder if any
of the other tools are close enough to parity that they'd be willing to
dogfood those as well.

Yes, it was, as I say in my post, I really enjoyed my time contributing
to this project, and I'll for sure continue to help you guys on whatever
I can 🙂 !

That's really cool to hear it did help some people 🙂

Well, it really depends on what you call "close enough". I think one
of
the other major problem with llvm binutils is that the outout of some
tools are slightly different from their GNU equivalent, which could be a
problem for some users.

Though, I truly think that a normal user that wants to play with ELF
binaries (I can only say this to ELF, as I didn't really focus on other
formats) will be able to find the equivalent in the llvm binutils suite
(very often, the options are exactly the same, so that the transition is
very easy).

Thanks for sharing the write-up, looks like you made great progress on this.

Are there any tracking issues for missing llvm-objdump functionality
or options? It's a fairly trivial one but I note llvm-objdump doesn't
accept -march yet for instance.

Do you know of any efforts to make llvm-mc compatible with GNU as, or
to make an alternative driver that is?

Best,

Alex

There isn't one, but if you wanted to start one and cc me/Jordan that would
be awesome. And probably Paul as well if he wants to continue working.

There isn't one that I know of, but we could start one. For me that's
been
much lower priority since I don't think anyone should call the assembler
directly and just use the compiler. :)

Thanks!
