Adjacent uses and multi-use addresses retain the area/cost ranking. -Rows are fixed test cohorts; columns are the compiler/allocator chapters. Each -cell is the sum of `_spillScaled`: retained split moves, including register -copies, weighted by loopDepth. Lower is better. **# tests counts -compilations** (program/CPU/ABI cases), including zero-spill cases, rather than -JUnit methods. The count and membership of each row stay fixed across columns. +Rows are fixed test cohorts; columns are compiler chapters. Each cell gives +**Ops / RA / X**: executed ARM+RISC-V instructions, the subset emitted for +allocator copies/rematerializations, and x86's loop-weighted split-move estimate. +**Cases D / X** counts measured dynamic program/target cases and x86 compilations; +membership and inputs stay fixed across columns. Native-library work is excluded. +Chapter 20 has no encoder, hence no dynamic counts. Lower is better within each +metric; see the [measurement details](../docs/regalloc-spills.md) for coverage. <!-- spill-matrix:start --> -| Test cohort | # tests | Ch 20 | Ch 21 | Ch 22 | Ch 23 | Ch 24 | Ch 25 | +| Test cohort | Cases D / X | Ch 20: Ops / RA / X | Ch 21: Ops / RA / X | Ch 22: Ops / RA / X | Ch 23: Ops / RA / X | Ch 24: Ops / RA / X | Ch 25: Ops / RA / X | |---|---:|---:|---:|---:|---:|---:|---:| -| Ch 20 | 39 | 360 | 576 | 430 | 442 | 441 | 491 | -| Ch 21 | 52 | | 1,072 | 960 | 961 | 948 | 1,077 | -| Ch 22 | 26 | | | 63 | 63 | 63 | 71 | -| Ch 23 | 24 | | | | 103 | 103 | 152 | -| Ch 24 | 58 | | | | | 1,387 | 1,503 | -| Ch 25 | 14 | | | | | | 1,862 | +| Ch 20 | 22 / 13 | — / — / 161 | 55,173 / 5,407 / 174 | 58,751 / 9,099 / 175 | 58,736 / 9,084 / 184 | 58,720 / 9,068 / 183 | 59,043 / 9,094 / 209 | +| Ch 21 | 20 / 18 | | 6,207 / 261 / 461 | 6,324 / 379 / 475 | 6,326 / 381 / 475 | 6,325 / 380 / 470 | 6,233 / 219 / 533 | +| Ch 22 | 14 / 8 | | | 198 / 60 / 7 | 194 / 56 / 7 | 194 / 56 / 7 | 332 / 136 / 11 | +| Ch 23 | 14 / 8 | | | | 630 / 160 / 36 | 630 / 160 / 36 | 1,106 / 442 / 36 | +| Ch 24 | 36 / 20 | | | | | 4,923 / 1,341 / 790 | 5,044 / 1,470 / 609 | +| Ch 25 | 2 / 12 | | | | | | 20 / 0 / 1,862 | <!-- spill-matrix:end --> |
