I can't understand why the dominance information is not garbage collected. Why is it not GTY-ed? Has it been GTY-ed in the past? As you imagine, my preference is to GTY more data, not less. Because I feel it improves a lot (as the dominance information demonstrates) the maintainability & readability of the GCC compiler (which, in my personal opinion, is even more important than the CPU time spent in cc1, because the rare resources are GCC developers, not processors.).
