For each basic block, a line is printed after the last line of the |
|---|
| 35 |
basic block describing the branch or call that ends the basic block. |
|---|
| 36 |
There can be multiple branches and calls listed for a single source |
|---|
| 37 |
line if there are multiple basic blocks that end on that line. |
|---|
| 38 |
In this case, the branches and calls are each given a number. |
|---|
| 39 |
There is no simple way to map these branches and calls back to source |
|---|
| 40 |
constructs. |
|---|
| 41 |
In general, though, the lowest numbered branch or call will correspond |
|---|
| 42 |
to the leftmost construct on the source line. |
