WebSofter Coalescing • Chaitin’s scheme coalesces everything that it can • Coalescing i and j can create ij º > max(i º, j °) May make ij harder to color In some contexts, this is important • We can limit coalescing to conservative cases Only create ij if ij º < k In this scenario, ij is trivially colored • We can also bias the color selection WebMar 1, 1992 · In particular, Chaitin's algorithm often produces excessive spilling on such programs. This results in underuse of the register set; the extra loads and stores inserted into the program for spilling also slow execution. An allocator based on an optimistic coloring scheme naturally avoids this problem. Such allocators delay the decision to spill ... hen\\u0027s-foot ky
