I'm going to take a break from working on these low-level tests and spend some time working top-down on the high-level structure of the...

Hi all, Sorry for having been quiet for so long, I have my university exams going on, and will be able to contribute only after the coming Friday. Thanks! -- Sanjoy Das http://playingwithpointers.com

One issue: don't use floating-point in LLVM. We want LLVM to behave the same on different computers, and practical...

Given a subscript pair, [c1 + a1*i + a2*j] and [c2], we can test for dependence using the RDIV test by rewriting as [c1 + a1*i] and [c2 - a2*j]. > I this look good, but, as you say below, we also need to work on the > top-level infrastructure.
