Hi Siddharth, this is documented at http://llvmweekly.org/reviewcorner
which is linked to in each issue. Pasting the guidance here for

For inclusion, the following should be true:
* Your patch has gone at least two weeks without substantial review
feedback OR this is your first patch to an LLVM project
* You have updated the patch based on any review comments received so far
* The patch has been compile tested against the current HEAD of the
appropriate LLVM project, and rebased if necessary
* You are willing to write a short two-sentence summary that explains
1) what the patch does, and 2) why people might interested.
