...sed) and a callgraph in the backend. So this might end up being more pass manager / infrastructure work than register allocation.

Hi, Here is a preliminary (monolithic) version you can comment on. This is still buggy, however, and I'll be testing for and fixing bugs over the next few days. I've used your version of the strong siv test. Thanks! -- Sanjoy Das. http://playingwithpointers.com -------------- next part -------------- A non-text attachment was scrubbed...

...efinition 2.10) are similarly incorrect. See http://www.elsevierdirect.com/companion.jsp?ISBN=9781558602861 particularly the replacement for page 46. I'm also confused about the math, but I'll keep working on it.

Hi all, Our use case for LLVM requires us to parse the .eh_frame sections emitted by MCJIT (for callee-saved-register spill slots, amongst other things). Does it make sense to have an in-tree parser for .eh_frame, given that it will make such tasks a lot easier? -- Sanjoy

...n and distance vectors whenever possible (strong SIV, basically). I think the current code is much clearer and would like your opinions on it. I have attached the patch and also pushed to the github repo I mentioned [1]. Thanks!
