| // Garbage collector liveness bitmap generation. |
| |
| // The command line flag -live causes this code to print debug information. |
| // The levels are: |
| // |
| // -live (aka -live=1): print liveness lists as code warnings at safe points |
| // -live=2: print an assembly listing with liveness annotations |
| // -live=3: print information during each computation phase (much chattier) |
| // |
| // Each level includes the earlier output as well. |
