37 // The MethodData object collects counts and other profile information | |
38 // during zeroth-tier (interpretive) and first-tier execution. | |
39 // The profile is used later by compilation heuristics. Some heuristics | |
40 // enable use of aggressive (or "heroic") optimizations. An aggressive | |
41 // optimization often has a down-side, a corner case that it handles | |
42 // poorly, but which is thought to be rare. The profile provides | |
43 // evidence of this rarity for a given method or even BCI. It allows | |
44 // the compiler to back out of the optimization at places where it | |
45 // has historically been a poor choice. Other heuristics try to use | |
46 // specific information gathered about types observed at a given site. | |
47 // | |
48 // All data in the profile is approximate. It is expected to be accurate | |
49 // on the whole, but the system expects occasional inaccuraces, due to | |
50 // counter overflow, multiprocessor races during data collection, space | |
51 // limitations, missing MDO blocks, etc. Bad or missing data will degrade | |
52 // optimization quality but will not affect correctness. Also, each MDO | |
53 // is marked with its birth-date ("creation_mileage") which can be used | |
54 // to assess the quality ("maturity") of its data. | |
55 // | |
56 // Short (<32-bit) counters are designed to overflow to a known "saturated" | |
57 // state. Also, certain recorded per-BCI events are given one-bit counters | |
58 // which overflow to a saturated state which applied to all counters at | |
59 // that BCI. In other words, there is a small lattice which approximates | |
60 // the ideal of an infinite-precision counter for each event at each BCI, | |
61 // and the lattice quickly "bottoms out" in a state where all counters | |
62 // are taken to be indefinitely large. | |
63 // | |
64 // The reader will find many data races in profile gathering code, starting | |
65 // with invocation counter incrementation. None of these races harm correct | |
66 // execution of the compiled code. | |
