[llvm-dev] Interval analysis in LLVM (original) (raw)

Is there any interval-based analysis framework in LLVM? I am looking for iteratively collapsing sub-regions of a control-flow graph and use the summary of the collapsed region in its enclosing region; something akin to Allen and Cocke's, "A program data flow analysis procedure," (https://amturing.acm.org/p137-allen.pdf).

This is not same as the region pass since a region is defined only over a single entry single exit in LLVM.
