| * | regalloc: fix lifetime construction for nested loops | 2025-12-15 | 1 | -17/+34 | |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, given something like ``` 1 a = ... 2 loop { // outer 3 b = do something with a 4 loop { // inner 5 ... 6 if (b < 0) 7 break 'inner; 8 if (b == 0) 9 return; 10 ... 11 } 12 } ``` Regalloc thought outer goes from 2..6, because 6 is the last place where flow jumps directly back to 2. So `a` would have the lifetime [1,7). However if neither the break nor return are taken, the inner loop repeats and then control could flow back to 7 -> 3. But now the physical location for `a` might have been clobbered between 8..10, which is wrong. This fixes that by making sure the outer loop is considered to span 2..10. The way I went about it might not be the best way of doing it. I'm not 100% certain that it's fully correct and will always find the correct loopend, either. It's surprising it took this long to hit this edge case. | ||||

| * | regalloc: optimize a little edge case better | 2025-12-10 | 1 | -4/+6 | |
| | | | | | | | | | | | | | With two-address instructions one needs to make sure the dst doesn't get allocated to the same reg as the right-hand operand: %r = mul %x, %y ; %y cannot be %r Except, if the operands are the same %r = mul %x, %x ; if %x is dead after this instr, it's fine to allocate %r to the same reg | ||||
