[llvm-dev] [GSoC 2016] Adding MachineModule pass to LLVM

Hello Ethan,

I have implemented one simple pass that counts the frequency of LLVM IR
instruction in a module. Other pass for very simple constant folding,
optimizing out unnecessary load operations and last one to obfuscate constant
0 with X ^ X where X is integer visible register.

     2. Could you give more details on your register allocation project?

I have pushed the code here
https://github.com/vivekvpandya/Research-Practice
Currently it generates Inference Graph using LiveIntervals, It can allocate
physical registers if no spill is required. I am currently working on
implementing simple spilling logic and applying cuckoo optimization to
minimize number of colors.
Some of the simple input are given in the test folder. I will add this
details to proposal.

 2. It would be good if you could include a resume/C.V. with your

I have added my Linked in Profile and it is fairly updated but I can upload
my resume to Google Docs and provide a link to that in my proposal.

 3. Has your GSoC 2014 work for Drupal been upstreamed into the
>     project's mainline code? (If yes, you should indicate this when you
>     talk about it in the proposal.)

My work during the GSoC 2014 is not related to upstream Drupal code but I
have developed an example iOS app that can communicate to Drupal via REST
APIs. Apart from this boiler plate code I have also reported few serious
issues with Drupal's REST APIs.

Sincerely,
Vivek
