36 | // The default sizes are x86-64-specific, and were found empirically. They have to cover the worst |
| 37 | // possible combination of registers leading to the largest possible encoding of each instruction in | |
| 38 | // the IC. | |
| 39 | // | |
| 40 | // FIXME: The ARM64 sizes are overestimates; if there is any branch compaction then we should be able | |
| 41 | // to get away with less. The branch compaction code currently validates the size of the IC before | |
| 42 | // doing any compaction, so we need to overestimate and give the uncompacted size. This would be | |
| 43 | // relatively easy to fix. | |
