The following is part of the profiling output of bottles.b.
Profiling output consist of three parts.
The first part is each instruction's count.
Instructions profile:
0: +: 1
1: +: 1
...
The second part is a list of simple loop in descending order. Position: Loop info : Loop body count
Simple loops:
463: [-]: 11371
1043: [-]: 11371
2231: [-]: 11371
1795: [-]: 5202
1799: [-]: 5202
29: [-]: 5145
...
The third part is a list of non-simple loop in descending order.
Non-simple loops:
95: [<+>-]: 23100
1861: [<+>-]: 22650
38: [>+>+<<-]: 4950
49: [<<+>>-]: 4950
1804: [>+>+<<-]: 4851
1815: [<<+>>-]: 4851
...
We can compile bf into native x86-64 assembly code with option -c. With the use of exec.sh, we can compile source bf file into
assembly file and generate an executable.
