| 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. | |
