[PATCH] D15722: [WIP][Polly] SSA Codegen

[Michael Kruse via llvm-commits]

Meinersbur added a comment.

Backtracking sounds like a function to get the generated value on demand, and following the control flow upstream by calling itself. Sounds like a reasonable idea to avoid generating too many unused PHIs.

But I don't know whether it even could introduce a scaling problem and therefore worth the increased implementation complexity (or maybe it's even simpler?)

What do you think?
