| 2 | // ms_print work as they should. A threshold of 10% is a good choice for |
| 3 | // this file, because in some parts of the tree it renders all children |
| 4 | // insignificant, and in others parts of the tree it renders only some |
| 5 | // children insignificant. |
| 6 | // |
| 7 | // Also, it's deliberate that the 'malloc(2000)' and 'my_malloc1(500)' calls |
| 8 | // are in 'main' -- at one point, ms_print was failing to connect some |
| 9 | // children arrows when a more significant child didn't have any children of |
| 10 | // its own, eg: |
| 11 | // |
| 12 | // | |
| 13 | // ->20.00% (2000B) 0x804846A: main (thresholds.c:43) |
| 14 | // |
| 15 | // ->13.00% (1300B) 0x80483A4: my_malloc2 (thresholds.c:16) |
