| 21 | * The following lookup table is intended to be used when a literal string of | |
| 22 | * the number of bytes is required (for example if it needs to be stringified). | |
| 23 | * It can also be used for generic shortcuts of power-of-two sizes. | |
| 24 | * This table is generated using the AWK script below: | |
| 25 | * | |
| 26 | * BEGIN { | |
| 27 | * suffix="KMGTPE"; | |
| 28 | * for(i=10; i<64; i++) { | |
| 29 | * val=2**i; | |
| 30 | * s=substr(suffix, int(i/10), 1); | |
| 31 | * n=2**(i%10); | |
| 32 | * pad=21-int(log(n)/log(10)); | |
| 33 | * printf("#define S_%d%siB %*d\n", n, s, pad, val); | |
