<div>Hi,<br>
<br>
</div>
I am a graduate student in computer science.I have taken a
programming languages course this semester and I am having
great fun building interpreters.I am planning to build toy
compilers in the winter.I would love to participate in GSOC
2016 contributing to LLVM.Could anyone let me know desirable
skills should be developed to contribute to LLVM ? Also I
would like to know the open projects in LLVM for Google
Summer Of Code 2016.<br>

What skills you need for GSoC depends entirely upon what sort of
LLVM-based projects you want to do. Many LLVM-based projects
requiring knowing how to write LLVM passes and doing either analysis
or optimization on the LLVM IR. For such projects, I'd recommend
learning how to write an LLVM pass (which is well documented at
<a class="moz-txt-link-freetext" href="http://llvm.org/docs/WritingAnLLVMPass.html">http://llvm.org/docs/WritingAnLLVMPass.html</a>.<br>
<br>
However, some GSoC students work on Clang (and therefore need to
understand how to analyze and manipulate Clang's AST). Others may
work on the code generator portions of LLVM (which requires
understanding the MachineInstr IR or the MC layer).<br>
<br>
I recommend that you learn whatever interests you. When it comes
time to worry about GSoC, you can then suggest a project that
leverages what you've learned.<br>
<br>
As far as GSoC projects, I think it's too early to have a list of
those up yet. I think we'll have a more up-to-date list in the
spring. That said, if you're looking for projects, you can look at
the open projects page at <a class="moz-txt-link-freetext" href="http://llvm.org/OpenProjects.html">http://llvm.org/OpenProjects.html</a>. Fixing
open bugs in the LLVM and Clang bug database would also be a good
way to start learning about Clang and LLVM. You can also look at
LLVM sub-projects such as lldb, ldb, and Polly.<br>
<br>
As for myself, I tend to mentor projects that instrument programs in
some way (usually to improve their security, but I've also mentored
a performance-bug finding tool). You can read about my work (nearly
all of which uses LLVM) on my publications page at
<a class="moz-txt-link-freetext" href="http://www.cs.rochester.edu/u/criswell/pubs.html">http://www.cs.rochester.edu/u/criswell/pubs.html</a> to get a sense of
the sorts of things that interest me. In a nutshell, I like
security, and I like using compilers to change operating system
kernel code.<br>
