...r option of trying to generate some fake set of heaps that accurately represent the conflicts in both is, well, difficult :) > _______________________________________________ JSC is able to make better use of the original TBAA design by encoding the access path within the type itself. Roughly: JSCType->Class->Field/Index This is what we're doing with C++ struct-path TBAA now, but simpler because only one access path is legal. JSC does need a hierarchical representation which makes TBAA a perfect fit. The only decision point to make now is whether to allow current TBAA to apply to ca...
